Description

201040808 VI. Description of the Invention: [Technical Field] [0001] The present invention relates to a touch panel, and more particularly to a new junction-structure touch panel that compositely senses bending of a substrate The pressure touch and the touch of the human body and the non-contact due to the bending of the substrate are used to generate the touch signal, and thus the multi-touch point can be recognized. [0002] 先前 [Prior Art] Generally, a touch panel is an input device attached to a display device such as an LCD (Liquid Crystal Display), a pdp (plasma display panel), an OLED (Organic Light Emitting Diode), and AM〇LEI> (active matrix organic light-emitting diode), and when the object such as a finger or a pen touches the touch panel, a signal corresponding to the touch point is generated. The touch panel is widely used in portable devices, industrial devices, DIDs, and the like. 〇 Traditional touch panels are implemented in various types, such as electrochamber, optical, and electrostatic. Between them, the resistive touch panel is simple to manufacture and inexpensive to manufacture, and is most widely used. 099107997 Figure 1 shows an example of a resistive touch panel. In Fig. 1, the touch panel includes a first substrate 3 and a second substrate 5 which face each other on the display device 1. A transparent conductive material such as ITO (Indium Tin Oxide) is applied on the upper surface of the first substrate 3 and the lower surface of the second substrate 5, respectively, to thereby form the transparent conductive layers 7 and 9. A plurality of resistance points 11 are provided on the upper surface of the first substrate 3 and a plurality of resistance points are also provided on the lower surface of the second substrate 5, although not shown. Form No. A0101 « _ Page 5 / Total 1 page 0993254534-0 201040808 As shown in Fig. 1 'If an object (such as stylus 17) contacts the surface of the second substrate 5, the second substrate 5 is bent, and the conductive layer 9 formed at the lower portion of the second substrate 5 contacts the conductive layer 7 formed on the upper surface of the first substrate 3. Then, the voltage applied between the conductive layers 7 and 9 is dropped by a resistance value obtained at the corresponding resistance point 11, and the detected voltage due to the change in the resistance value is analogized to digital. (Ad) The converter 13 converts into a digital signal. The digital signal is then transmitted to a central processing unit (CPU) 15, which then obtains the coordinate value of the touch point. This resistive touch panel is widely used because its manufacturing process is simple and manufacturing cost is low. However, the resistive touch panel should be configured to satisfy the conductive layer 7 and 9 having a uniform surface resistance value to detect the voltage difference based on the position of the touch point on the touch panel. It is very difficult to meet this condition. Further, during the application of the transparent conductive material, the thickness of the coated transparent conductive material should be strictly controlled. For this reason, there is a problem that causes the cost of the process to rise. Further, when the resistive touch panel is used for a long time, there is a problem of low durability, which is caused by a gradual change in the characteristics of the conductive layer 9 of the second substrate 5. As a result, damage to the conductive layer 9 is caused, thus causing an error in position interpretation. Another problem with the resistive touch panel is that two substrates 3 and 5 are used, and a transparent conductive material such as ΙΤ0 is applied over all areas of each of the substrates 3 or 5. If the two substrates 3 and 5 are used and the transparent conductive material such as (10) is applied to the plurality of layers, the transparency of the touch panel is lowered, thereby causing low quality of the display device 1. In addition, the conventional resistive touch panel has some flaws because it cannot recognize the multi-touch operation in which multiple touch points occur simultaneously on the touch panel. 0993254534 - Form No. A0101 Page 6 of 1 201040808 For example, if a person writes on an electronic blackboard, the side of the person's hand is stuck on the electronic blackboard, or if many people write on the electronic blackboard at the same time, the multi-touch operation may occur. In this case, the conventional resistive touch panel cannot recognize the multi-touch operation, or it may operate incorrectly. In addition, when the conventional resistive touch panel detects the touch control by the analog signal, an expensive analog to digital (AD) converter 13 is required to convert the analog signal into a digital signal. This type of signal-to-digital conversion has caused a delay in time. In addition, the resistive touch panel needs to be calibrated, for example, with respect to the zero point adjustment of the resistance point. There are also various problems, and the conventional resistive touch panel is difficult to use for each case of the large-sized display panel 1. Among the different types of conventional touch panels, there is disclosed an electrostatic capacitive touch panel that senses the touch of a finger or an electrical conductor to generate a touch signal. Figure 2 shows a conventional electrostatic capacitive touch panel. In the example of the electrostatically charged touch panel described in FIG. 2, transparent conductive layers are respectively formed on the upper and lower surfaces of the transparent substrate 10, which is composed of a film, a plastic or a glass. And the metal terminal 12 for applying a voltage is divided into E9 corners of the transparent substrate 10. The transparent conductive layer is formed of a transparent metal of 1T0 (indium tin oxide) or ΑΤ0 (indium oxide). The metal terminals 12 respectively formed at the four corners of the transparent substrate 10 are formed by printing a low-resistivity conductive metal such as silver (Ag). Resistor networks are formed around the metal terminals 12, respectively. The resistor network is formed in a linearization pattern to uniformly transmit control signals over the entire surface of the transparent conductive layer. Protection 099107997 Form No. A0101 Page 7 of 100 201040808 The film is applied to the upper portion of the transparent conductive layer containing the metal terminal 12 if a high frequency alternating current (AC) voltage is applied to the capacitive touch panel The metal terminal 12 is dispersed on the entire surface of the transparent substrate 10. Here, if the transparent conductive layer formed on the upper surface of the transparent substrate 1 is gently touched by the finger 16 or the conductive object, a specific amount of current is absorbed into the human body, and then the current change is controlled. The current sensor in the device 14 is sensed. The controller 14 then calculates the amount of current at the four metal terminals 12, respectively, to thereby identify the touch points. . . . ': ..::. ... Since the capacitive touch panel uses the touch mode, its life span is longer. Since the electrostatic capacitive touch panel uses a single transparent substrate, the transparency of light is high. Since a special metal is applied to the surface of the electrostatic capacitive touch panel, its strength is strong. In particular, since the width of the inactive area is limited to the edge portion of the touch panel, there is an advantage in that when the touch panel is combined with the display device, the overall structure is slim. However, the electrostatic capacitive touch panel has a drawback in that it is impossible to perform a touch operation with a non-conductor (e.g., a nail, a glove, and a poem). The capacitive touch panel has a problem of causing erroneous operation due to noise (e.g., external static electricity). In addition, due to the capacitive touch panel (4) micro-current detection mode, it requires a highly responsive detector. In addition, as in the case of a resistive touch panel, the capacitive touch panel has problems that require calibration (e.g., difficulty with respect to the zero point of the resistance point), and problems with multiple identities.

One of the two types of touch cells is a capacitive touch cell having a three-terminal switching element and a touch pad, the touch pad is connected to a gate terminal of the switching element, and the two types of touch The other type of control cell is 099107997 with two conductive turns. Form No. A0101 Page 20 of 100 0993254534-0 201040808 Pressure touch cells, the conductive pads are configured at a distance from each other. The capacitive touch cell is formed in the separation region. The separation region is formed by dividing the effective region in the touch panel into a plurality of regions. In the touch panel, the actual touch is effective. Conducted on the district. A three-terminal capacitive switching element and a touch pad connected to the gate terminal of the capacitive switching element are disposed in each of the separation regions to thereby constitute a unitary capacitive touch cell. The gate terminal, the source terminal (hereinafter may be referred to as "input terminal"), and the drain terminal (hereinafter may be referred to as "output terminal") of the capacitive switching element are respectively connected to the first capacitive signal line, Two capacitive signal lines and a third capacitive signal line. In addition, if the state of the capacitive switching element is changed by a virtual electrostatic capacity, the virtual electrostatic capacitance is generated when a finger or a touch unit having a conductive characteristic similar to the finger gently contacts or approaches the touch pad. The touch panel detects the state of the capacitive switching element to obtain a touch signal. The pressure touch cell is also formed in the separation area, and the separation area is formed by dividing the effective area in the touch panel into a plurality of areas. In the touch panel, the actual touch is Executed on this active area. The first conductive pad and the second conductive pad, which are disposed in pairs and spaced apart from each other, are disposed in each of the separation regions to thereby constitute a unit pressure type touch cell. The first conductive pad and the second conductive pad are respectively connected to the first pressure signal line and the second pressure signal line. In addition, when the two substrates constituting the touch panel are in contact with each other by a touch unit (for example, a stylus pen), the first conductive pad and the second conductive pad are electrically short-circuited to thereby obtain a touch signal. According to the present invention, two different types of touch cells respectively have the basic structure described above as 099107997 Form No. A0101 Page 21 / Total 100 Page 0993254534-0 201040808. More detailed structures of touch cells in accordance with various embodiments of the present invention will be described in more detail below with reference to the accompanying drawings. Meanwhile, in the example of the specific embodiment to be described below, the switching element may be replaced by a thin film transistor (TFT). Therefore, the switching elements and the TFTs are indicated by equal component symbols. Fig. 3 is an exploded perspective view showing the external structure of the touch panel according to the present invention. Referring to Fig. 3, a touch panel according to the present invention is mounted on an upper surface of a display device 2A, wherein the first substrate 3A and the second substrate 60 face each other. The first substrate 30 and the second substrate 60 are composed of a material that transmits light, such as a transparent glass filled, a film, and a plastic. The drive integrated circuit (1C) 81 is mounted in the edge portion of the first substrate 3A or the second substrate 6A in the form of C〇F (film over-cladding) or C0G (silver-coated). Alternatively, the driver 1C 81 can be mounted in a panel in a polycrystalline germanium (P-Si) structure using a low temperature polycrystalline process. The driving 1 (: 81 is an integrated circuit for applying a detection signal and a gate signal to a signal line to be described later or obtaining a position detection signal and a gate signal from the signal line. Further, according to the present invention A preferred embodiment, diffusion, is further disposed between the display device 20 and the first substrate 30, which will be described later. Meanwhile, the specific embodiment of FIG. 3 has described The substrate 30 and the first substrate 60 are mounted on the upper surface of the display device 20, but the two substrates may be mounted in the display device 20. For example, in the example of the LCD, the first substrate 30 and The second substrate 60 forms a sheet on the liquid crystal panel, in which the TFT substrate and the color filter substrate are combined and then mounted in a BLU (backlight module) housing. In this example, according to the invention The touch panel can be embedded in the display device 20 in the form of 099107997 Form No. A0101, page 22 / page 100, 0993254534-0 201040808. Fig. 4 is a schematic diagram of the basic structure of the touch panel according to the present invention. 4 pictures The capacitive touch cell 31 and the pressure touch cell 70 are respectively arranged in a matrix form in the active area 100 of the touch panel. On the touch panel, the actual touch is performed. In the example, the capacitive touch cell 31 is configured with 2*2 resolution, and the pressure touch cell 70 is configured with 4*4 resolution, but this is only an example to help understand the invention. In fact, the respective touch cells are configured with a larger resolution. The capacitive touch cells 31 and the pressure touch cells 70 can be formed in regions that are isolated from each other within the active region. Therefore, if the two touch cells 31 and 70 are formed in isolation from each other, when the touch cell is formed, the pad can be mounted in a larger area, and the pad is connected to the signal line. The program becomes simple. In this example, only the touch input selected from both the pressure touch input and the tap input has to be detected at a suitable predetermined point on the active area 100. However, the capacitance is The touch cell 31 and the pressure touch cell 70 are formed in Examples of areas in the active area that are isolated from each other are very useful in dividing the use of the touch input area. According to another embodiment of the present invention, as shown in FIG. 4, the capacitive touch cell 31 And the pressure touch cell 70 is repeatedly formed in at least a portion of the active area. The capacitive touch cell 31 is formed in an area covering the four pressure touch cells 70 in FIG. Therefore, if the two touch cells 31 and 70 are formed in the overlap region, the two touch inputs can be effectively detected at any point on the active region 100. Of course, the fourth figure is A specific embodiment of the present invention. 099107997 Form No. A0101 Page 23 / Total 100 Page 0993254534-0 201040808 As shown in the example of the specific embodiment of the 24th embodiment, which will be described later, 'some capacitive touch cells 31 or some The pressure touch cell 70 can be independently mounted on the active area 1〇〇. First, referring to Fig. 4, the basic structure of the capacitive touch cell 31 will be described. A plurality of first capacitive signal lines 32, second capacitive signal lines 34, and third capacitive signal lines for transmitting and receiving position detection signals are disposed on the first substrate 30 or the second substrate 60. 36. In the depicted embodiment, the first capacitive signal line 32 is mounted with wires in a lateral direction, and the second capacitive signal line 34 and the third capacitive signal line 36 are longitudinally mounted with wires, but this It is only a specific embodiment of the invention. The respective signal lines can be mounted on the substrate regardless of the direction in which the wires are mounted, such as the longitudinal, lateral, and diagonal directions. The basic structure of the capacitive touch cell 31 is shown in Fig. 4. Each of the capacitive touch cells 31 includes at least a three-terminal capacitive switching element 40 and a touch pad 50. The capacitive switching capacitor 40 is desirably formed by a TFT. The gate terminal of the capacitive TFT 40 of each capacitive touch cell 31 is connected to the first capacitive signal line 32, and as depicted, The input terminal and the output terminal are respectively connected to the second capacitive signal line 34 and the third capacitive signal line 36. A touch pad 50 composed of an electrical conductor is connected to the gate terminal of the capacitive TFT 40. The gate terminal opens/closes the switching element by a virtual electrostatic capacity generated by contact or proximity of a human body or a touch unit. The touch unit has a conduction characteristic similar to that of a human body. More specifically, the touch position detector 80 applies a position detection signal to the first capacitive signal line 32 and the second capacitive signal line 34, and when the power is 24 pages/total 1 page 099107997 Form nickname A0101 201040808

The capacitive TFT 40 receives the position detection signal from the third capacitive signal line 36 when the virtual electrostatic capacitance generated in the touch pad 5 is turned on to detect the touch position. However, such a signal input/output mode is merely a specific embodiment of the invention. In other words, the position detection signal can be transmitted and received via one of the three capacitive signal lines 32, 34, and 36, and the gate signal can pass through the three capacitive signal lines 32, 34, and 36. Another capacitive signal line is applied to the gate terminal of the capacitive TFT 40, and an impedance signal can be applied to the capacitor via the remaining capacitive signal lines of the three capacitive signal lines 32, 34, and 36. The input terminal or output terminal of the TFT 40. FIG. 5 is a schematic view showing that a virtual electrostatic capacitance is formed in the touch pad 50 of the capacitive touch cell 31. Referring to FIG. 5, it is assumed that the distance between the finger 26 and the touchpad 50 is "d". When a finger 26 of a person is brought close to the touchpad 5, as shown in the right hand side of the Chinese figure 5 As can be seen from the equivalent circuit, a static capacitance C exists between the finger 26 and the 'touch pad 50'. This is because the Earth has picked up the role of virtual grounding.

When the human body is generally in contact with an electrical conductor, the static capacitance of tens of pFs is present in the case where the earth plays the role of a virtual ground. In the case where the human body approaches the electric conductor in a non-contact state, depending on the permittivity "e" of the object between the human body and the electric conductor, there may be a static capacitance of about several pFs. Therefore, the human body can be used. The capacitive TFT 40 is turned on/off by the electrostatic capacitance feature. As shown in FIG. 4, an example has been provided in which the first capacitive signal line 32 becomes high impedance to thereby increase the discharge constant to detect a voltage formed across the dummy capacitor, which is shaped by a The touch pad 50 is used as a specific embodiment for detecting a light touch by the capacitive TFT 40. However, '099107997 Form No. A0101 Page 25/Total 1 Page 0993254534-0 201040808 More preferably, two or more capacitive TFTs are mounted in each of the capacitive touch cells 31 to provide The method of not performing the first capacitive signal line 32 to a high impedance and performing signal processing more stably, which will be described later. In the following, referring to Fig. 4, the basic structure of the pressure touch cell 70 will be described. A plurality of first pressure signal lines 42 and a plurality of second pressure signal lines 44 are disposed on the first substrate 30 or the second substrate 60 for transmitting and receiving position detection signals. In the depicted embodiment, the first pressure signal line 42 is mounted laterally/wired 5 and the second pressure signal line 44 is longitudinally mounted with wires, but this is only a specific embodiment of the present invention. Just like the capacitive signal line as described above. The respective signal lines can be wired to the substrate regardless of the direction in which the wires are mounted, such as longitudinal, lateral, and diagonal directions. Each of the pressure touch cells 70 includes a pair of first conductive pads 46 and second conductive pads 48, unlike the capacitive touch cells 31, and the first conductive pads 46 and the second conductive pads 48 Configured at a distance from each other. The first conductive pad 46 is coupled to the first pressure signal line 42 and the second conductive pad 48 is coupled to the second pressure signal line 44. When the second substrate 60 is pressed by a pressure touch (for example, a stylus) of the touch unit, in the example of the pressure touch cell 70, the two conductive pads 46 and 48 that become a pair generate electricity. Short circuit to get the touch signal. For example, when the two conductive pads 46 and 48 in the pressure touch cell 70 are short-circuited with each other, the position detection signals respectively generated from the driving 1C 81 of the touch position detector 80 are It is applied to the first pressure signal line 42 and is forwarded to the second pressure signal line 44. The 099107997 Form No. A0101 Page 26 / Total 100 Page 0993254534-0 201040808 The touch position detector 80 reads the signal that has been received by the second pressure signal line 4 4 and obtains the corresponding pressure touch cell. The coordinate value of 70. This signal input/output method is merely a specific embodiment of the invention. In other words, the position detection signal can be transmitted and received to one of the pressure signal lines of the two pressure signal lines 42 and 44, or can be transmitted from one of the two pressure signal lines 42 and 44. And receiving, and the impedance signal can be applied via another pressure signal line. The touch panel according to the invention comprises the capacitive touch cell 31 and the pressure touch cell 70, the input modes of which are different from each other. However, in the two different input mode examples, the touch signal can be detected in the same way as the high and low states of the position detection signal. This means that the equivalent control integrated circuit can be used, unlike the conventional example where different signal detection processes are used in the two input modes and different types of controllers are used. That is, in the present invention, as shown in FIG. 4, the position detection signal is transmitted and received to and from the capacitive touch cell 31 and the capacitive touch cell 70. The touch cell 31 and the pressure touch cell 70 transmit and receive the position detection signal. The drive 1C 81 can be incorporated into a single 1C. In more detail, as shown in FIG. 4, the touch position detector 80 includes a driving 1C 81 for transmitting and receiving a position detecting signal, a timing controller 82 for generating a time-sharing signal, and signal processing. And a memory unit 85, the signal processor 83 provides a time-division position detecting signal to the driving 1C 81 according to a clock supplied from the timing controller 82, and processes the signal received from the driving 1C 81 to grasp Taking the touch position, the memory unit 85 has an address corresponding to the coordinate value of the capacitive touch cell 31 and the pressure touch cell 70. Although not shown in the figure, the electric power supply is 099107997 Form No. Α0101 Page 27/100 pages 0993254534-0 201040808 Benefits can be included in the touch position detector 8 。. The operation of the touch position detector 80 will be described later with reference to the waveform diagram. 6 is a plan view showing an example in which a touch cell is disposed in a first substrate, and FIG. 7 is a cross-sectional view showing a touch panel according to an embodiment of the present invention, in which the touch cells 31 and 7 are displayed. The structure of each layer in the raft. Referring to FIG. 6, as in FIG. 4, the capacitive touch cell 31 is configured with a resolution of 2*2, and the pressure touch cell 7 is configured with a resolution of 4*4. As shown in Fig. 6, the two touch cells 31 and 7 can be formed on the first substrate 30. The two touch cells 3 and 7 are formed on the first substrate 30 for charging the two conductive pads 46 and 48 of the pressure control cell 7 A charging unit is mounted on the second substrate 60. Alternatively, although this will be described later, a transparent conductive layer 62 or a charge spacer 25c is formed on the second substrate 6A to thereby enable the two conductive pads 46 and 48 to be short-circuited with each other. The capacitive touch cell 31 and the pressure touch cell 7 are formed to cover the repeated dust domain in the embodiment of the present invention in FIG. 6, but as depicted, the capacitive touch cell The touch pad 5 of 31 and the two conductive pads 46 and 48 of the pressure touch cell 70 are formed such that they do not overlap each other and are insulated. In more detail, referring to FIG. 6, the predetermined area is cut in the touch pad 5A of the capacitive touch cell 31, and the two conductive pads 46 and 48 of the pressure touch cell 70 are A distance is formed in the cut region from the touch pad 5A. Of course, one of the two conductive pads 46 and 48 of the pressure touch cell 70 can be formed in each of the cut regions, and the other one can be formed on the opposite substrate. According to this configuration, the capacitive touch cell 31 and the pressure touch cell 7 can be formed on the first substrate 3's repeating form number A0101 099107997, page 28/100 pages 201040808 area. . Therefore, the two touch inputs can be independently measured in equal areas. Since the capacitive touch cell 31 and the pressure touch cell 70 cover the repeating region, it can be predicted that the two touch cells 31 and 70 are both in the case where the human body or the conductive material is pressurized. reaction. Therefore, in the case where two touch signals have been sensed, the two touch signals need to be processed. In this case, for example, in the example where the two touch signals are sensed at the appropriate positions of the touch panel, the touch signals of the high resolution in the pressure touch cell 70 can be Recognized as a valid touch input. That is, if the signal sensed in the pressure touch cell 70 is processed on a priority basis, the two touch inputs can be processed and the signal sensed in the capacitive touch cell 31 It is then processed. Meanwhile, in order to effectively achieve the touch input of the electrostatic capacitance mode, the touch pad 50 of the capacitive touch cell 31 should have a width of several millimeters (mra) or more. Therefore, it is difficult to recognize a high-resolution touch input having a font or a picture in the capacitive touch input mode. However, the pressure touch cell 70 can recognize the touch input of a stylus or a non-conductor such as a glove or a nail. In addition, the pressure touch cell 70 can be mounted at a pitch of several hundred micrometers (em) to enable high resolution touch input. The size of the 0. 8mm*0. 8ππη is formed by forming the capacitive touch cell 31 to a size of 8 mm*8 mm. Therefore, one hundred (100) pressure type touch cells 70 are contained in one (1) capacitive touch cell 31. That is to say, again, the illustration of Fig. 6 is merely an illustration to help understand the invention. In fact, the pressure touch cell 70 can be configured one hundred (100) times or higher than the higher resolution of the capacitive touch cell 31. 099107997 Form No. A0101 Page 29/Total 100 Page 0993254534-0 201040808 Referring to the cross-sectional view of FIG. 7, the first substrate 30 and the second substrate 60 are disposed with a plurality of spacers 25 spaced apart by a distance. The spacer 25 includes a spherical spacer 25a and a pattern spacer 25b. The spherical spacer 25a is composed of an insulator, and rolling contact occurs between the first substrate 30 and the second substrate 60. The pattern spacer 25b is also The insulator is constructed and one end is patterned and fixed on the substrate, and the other end thereof contacts or connects the facing substrate. When the bending occurs in the second substrate 60, the spherical spacer 25a is compressed and deformed, and is supported around the point where the substrate is bent. The pattern spacer 25b is fixed between the two substrates 30 and 60 and is disposed at a boundary portion of the touch cells 31 and 70. As depicted, the two spacers 25a and 25b can be used together. In the specific embodiment depicted in FIG. 7, as in the example of FIG. 6, the capacitive touch cell 31 and the pressure touch cell 70 are formed on the upper surface of the first substrate 30. on. An example of forming the capacitive touch cell 31 is shown on the left hand side of Figure 7, and an example of forming the pressure touch cell 70 is shown on its right hand side. In the example in which the two touch cells 31 and 70 are formed on the substrate as described above, a charging unit is required in the facing substrate to charge the two conductive pads of the pressure touch cell 70. 46 and 48. In the example depicted in Figure 7, the charging unit is formed as a transparent conductive layer 62 on the lower surface of the second substrate 30. As another embodiment different from the specific embodiment of Fig. 7, the two touch cells 31 and 70 may be formed on separate substrates. In this example, the touchpad 50 of the capacitive touch cell 31 can function as a charging unit that charges the two conductive pads 46 and 48 of the pressure touch cell 70. Further, the two conductive pads 46 and 48 may be formed on different substrates on 099107997 Form No. A0101, page 30/100 pages, 0993254534-0 201040808, respectively, and thus charged by mutual contact. For example, two conductive pads 46 and 48 may be formed on the respective facing substrates and divided and formed in each of the pressure touch cells 7A. In this example, it is very important to straighten the conductive pads 46 and 48 such that the two conductive pads 46 and 48 are in stable contact with each other. As an alternative example, a conductive pad can be divided and formed in each of the pressure touch cells 7 and another conductive pad can be formed on the entire surface facing the substrate (similar to the formation in FIG. 7). An example of the transparent conductive layer). In this example, stable contact between the conductive pads is contemplated without the need to align the conductive pads at the respective locations. Although the touch panel has been conceptually depicted in FIG. 4, the touch control 50, the first conductive pad 46, and the second conductive pad 48 are preferably formed to overlap with respective signal lines on the first substrate 30. . By doing so, the area of the touch pad 50 and the two conductive pads 46 and 48 can be formed as large as possible, and transparency can be improved. Referring to FIGS. 6 and 7, the gate terminal 56 of the capacitive switching element 40 is coupled to the first capacitive signal line 32, and the source terminal 57 is coupled to the second capacitive signal line 34, and the drain terminal 58 is connected to the third capacitive §fl line 3 6 . In addition, the capacitive switching element 4 〇 includes an active layer 28 that overlaps the gate terminal 56 and forms a channel between the source terminal 57 and the drain terminal 58. The active layer 28 is formed such that the source terminal 57 and the drain terminal 58 overlap each other. An ohmic contact layer 29 for ohmic contact between the source terminal 57 and the drain terminal 58 is further formed on the active layer 28. The active layer 28 is formed of amorphous germanium (A-Si) or polycrystalline spine (P-Si). Here, a gate insulating layer 45 is formed on the gate terminal 56, and absolutely 099107997 Form No. A0I01 Page 31 / Total 100 Page 0993254534-0 201040808 Edge layer 4 7 is formed at the source terminal 5 7 and the drain Extreme 5 8 on. The touch pad 50 and the two conductive pads 46 and 48 are formed using ΙΤ0 or ΑΤ0 or ΙΖ0 (indium zinc oxide), CNT (carbon nanotube) or the like. A connection point 39 using a contact process of IT0, metal, or the like is used to connect the touch pad 50 and the two conductive pads 46 and 48, respectively, using the signal line. Meanwhile, the component symbol 51 refers to a flattening layer 51 on which an insulating material is applied for planarization of the first substrate 30, which may not be used as needed. Although not shown in the drawings, a light intercepting layer may be mounted on the capacitive TFT 40. The light intercepting layer can be formed using a source metal or a gate metal. The reason why the light blocking layer is formed on the upper surface of the capacitive TFT 40 is to prevent the capacitive TFT 40 from reacting with light and malfunction. A plurality of TFTs and the like are additionally used in a specific embodiment to be described later, wherein a light intercepting layer may be formed in all of the plurality of TFTs and the like, and the like, FIGS. 4 to 7 depict a touch panel according to the present invention. The basic composition. The operation of the touch panel based on this basic composition will be described below with reference to Figs. 4 to 7. In the example of the touch panel of the present invention, the two touch cells 31 and 70 have different input methods and different reaction mechanisms respectively, and the reaction mechanism inputs the touch input to each of the touch cells 31 or 70. Respond to identify the coordinates. Therefore, the capacitive touch cell 31 and the pressure touch cell 70 respectively perform individual actions, but the drive 1C 81 of the touch position detector 80 integrates their signals and controls the two touch cells. Touch input of elements 31 and 70. Although the signal lines of the capacitive touch cell 31 and the pressure touch cell 70 are separately arranged, the position detection signal is 099107997. Form number A0101 page 32/100 page 201040808 via the single driver IC 81 Transfer to their respective signal lines and receive them from their respective signal lines. Although the capacitive touch cell 3 and the signal line of the pressure touch cell 70 act individually as if they were asynchronous signals, they preferably operate like a synchronized signal. The touch position detector 80 provides a continuous scan pulse to the first capacitive signal line 32 and the first pressure signal line 42 via the drive ic 81, respectively. If the supply scan pulse is spread over the entire area of the touch panel, another scan pulse is continuously supplied after a short pause period.

To all of this signal line. As with the specific embodiment of the present invention, the time taken to supply all of the signal lines for one cycle of scanning pulses will take from tens to hundreds of milliseconds (ms). Therefore, the position detection signal is obtained in each unit touch cell 31 or 70 in a very short period. ❹ First, when the high voltage of the position detecting signal is applied via the first capacitive signal line 32 in each of the capacitive touch cells 31, the capacitive Tft 40 is turned on. Then, when the position detecting signal is low and cut off, the capacitive TFT 40 is turned off. Incidentally, if the touch input is generated by the finger approaching the touch pad 5 产生 in the capacitive touch cell 31, the 'formed on the finger is friendly' The virtual capacitor between 5 被 is charged. Thereafter, the position detecting signal is cut off at the gate terminal of the capacitor STFT 40. Then, if the position detecting signal becomes a high impedance state, a discharging action occurs in the dummy capacitor, and the off time of the capacitive TFT 40 is delayed. Therefore, the touch position detector 80 measures the delay time of the signal output to the third capacitive signal line 36, and obtains the touch signal in the corresponding touch cell. If the second substrate 60 is pressed by a touch unit (such as a stylus or a nail), the second substrate 60 is bent or bent downward, and is located on the second substrate 099107997 Form No. A0101 Page 33 of 1 The transparent conductive layer 62 on the lower surface of the page 0993254534-0 201040808 60 charges the two conductive pads 46 and 48 of the pressure touch cell 70. Here, the position detection signal applied via the first pressure signal line 42 is transferred to the second conductive pad 48 via the first conductive pad 46 and extends to the second pressure connected to the second conductive pad 48. The analog signal line 44 is input to the drive 1C 81. Therefore, the touch position detector 80 reads the signal output to the second pressure signal line 44 to thereby obtain the touch signal in the relevant touch cell.

Fig. 8 is a waveform diagram showing an example of recognizing a touch signal in the specific embodiment of Fig. 4, and Fig. 9 is a conceptual block diagram showing an example of a memory unit according to an embodiment of the present invention.

Referring to the waveform diagram of FIG. 8, the driving 1C 81 applies the time division position detecting signals of DC 1 and DC 2 to the first capacitive signal line 32, and also divides the DP 1 , DP 2 , DP 3 and DP 4 The time position detection signal is applied to the first pressure signal line 42. The pulse period applied to the first pressure type signal line 42 is "T1". The pulse period applied to the first capacitive signal line 32 is "T2", which includes the observation time at the high interval of the pulse and the interval after the interval of the pulse. In the block diagram of Fig. 9, the address in the memory unit 85 corresponds to the position of each of the touch cells 31 and 70 in the embodiment of Fig. 4. The capacitive touch cell 31 located on the top left hand side of FIG. 4 corresponds to the M1 address in the block diagram of FIG. 9 and the pressure touch cell 70 corresponding to the top of the left hand side. The M3 address in the block diagram of Figure 9. In this way, the M1, M2, Mil, and M12 addresses in the block diagram of FIG. 9 are the addresses corresponding to the respective positions of the capacitive touch cells 31 in the specific embodiment of FIG. 4, and M3 is The M10 and M13 to M20 addresses are addresses corresponding to respective positions of the pressure touch cells 70. 099107997 Form number A0101 Page 34 of 100 0993254534-0 201040808

If the human body or the conductive object is close, and thus the tap input occurs in the capacitive touch cell 31 located on the top left hand side of FIG. 4, that is, the capacitance at the position corresponding to the M1 address The timing of the touch TFT 31 when the position detecting signal ends in the associated capacitive touch cell 31, that is, at the time point of t3, the closing operation of the capacitive TFT 40 is performed. The charge that is accumulated by the electrostatic capacitance is delayed, and the gate voltage is in an open state during the observation time. When the signal input to the third capacitive signal line 36 connected to the associated capacitive touch cell 31 is delayed, the touch position detector 80 obtains the touch signal corresponding to the M1 point of the appropriate position. The touch signal is forwarded to a central processing unit (CPU) not shown. The obtained touch signal is stored in the M1 address of the memory unit 85. If the pressure touch input is touched by a touch unit, such as a stylus (or includes a part of the human body), it occurs at the lower end of the right hand side in Fig. 4 .:: ;: ...

In the pressure touch cell 70, that is, the position i corresponds to the position of the M20 address in the pressure touch cell 70; when the DP4 signal is applied to the first pressure signal line 42 The position detection signal SP4 is input through the second pressure type signal line 44 at the time t5 to t6. The touch position detector 80 determines the timing of the signal input to the second pressure signal line 44. The second pressure signal line 44 is connected to the associated pressure touch cell 70, thereby obtaining corresponding The touch signal of the M20 point in the proper position. Then, the touch position detector 8 transfers the touch signal to the CD 11 ' and stores the obtained touch signal in the M20 address of the memory unit 85. At the same time, the tap input through the capacitive touch cell 31 and the pressure touch input via the pressure touch cell 70 as described above are in the phase 099107997 form bat number A0101 page 35 / total 100 pages In the example where 0993254534-0 201040808 occurs together, the pressure touch input is selected as a valid signal. However, as in this example, the touch inputs via the capacitive touch cells 31 of the two different types of touch inputs of different types that have been detected in the equal regions can be processed based on the priority basis. Of course, different types of the two touch wheel inputs can be processed as valid signals. The reason why the obtained touch signal is stored in the memory unit 85 is because the image obtained by the touch position detector 80 or the CPU in the "busy" state during the processing of a plurality of signals is obtained. Touch signals are often not recognized and lost. In order to prevent this, as shown in Fig. 9, the memory unit 85 has an absolute address corresponding to the respective coordinate values of the capacitive touch cell 31 and the pressure touch cell 70. The touch position detector 80 forwards the obtained touch signal to the CPU and simultaneously stores it in the designated address of the cipher unit 85. Regarding the entire active area 100, the touch position detector 8 scans the position detection signal once, and then reads the memory unit 85 - the pause time to judge whether there is a lost signal. If there is a lost communication, the touch position detector 8 〇 re-storing the lost signal. The basic composition and operation of this invention have been described in the specific embodiments of the invention described above. Incidentally, with the basic composition, the signal line is wired in the active area 100, the capacitive touch cell 31 and the pressure touch cell 70 are respectively arranged in a matrix form, and the TFT It is installed in the touch cell, and the touch cell has a structure similar to that of the display device 2 (for example, LCD or AMOLED). Therefore, the touch panel according to the present invention can be fabricated using a TFT substrate process of a display device, and product reliability and mass productivity of the display device are confirmed. Incidentally,

099107997 Form No. A0101 Page 36 / Total 100 Page 0993254534-0 201040808 'In the example of the touch panel mounted on the upper surface of the display device, the overlay effect of the exposed waveform pattern can be obtained by the touch The panel signal line and the interference between the display device 2 and the signal line occur. This invention provides some solutions to prevent this moiré. The capacitive touch cell 31 and the pressure touch cell 70 are arranged in a matrix form in the same manner as the unit pixels are arranged in a matrix form in the display device 20 such as an LCD. Therefore, if the size of the capacitive touch cell 31 and the pressure touch cell 7 以 correspond to the unit pixel of the display device 20 in an integer ratio, and if the signal line of the touch panel is like a virtual vertical The line is located on the same line with respect to the signal line (for example, the gate line and the data line of the display device 20), and the signal interference between the touch panel and the signal line of the display device can be greatly reduced. - Although the unit pixel of the display device 20 is designed with a very high resolution, since the capacitive touch cell 31 should obtain a region of several millimeters (•·mm) for the touch detection, the capacitive touch The cell 31 has to be configured with a resolution lower than the unit pixel. Therefore, the capacitive touch cell 31 is configured with an integer ratio reduced in resolution compared to the unit 0 pixel of the display device 2, and the capacitive signal line is compared to the signal line of the display device 20. 32, 34, and 36 are attached to the wires to an extent that extends in an integer ratio. At the same time, since the pressure touch cells 70 can be configured with a very high resolution, they are arranged equal to the unit pixels of the display device 20, and the pressure signal lines 42 and 44 are connected to the signal line of the display device 20. The degree of configuration in the same way. Of course, as in the example of the capacitive touch cell 31, the pressure touch cell 70 is configured in an integer ratio reduced resolution compared to the unit pixel of the display device 20, and compared to the display device. 20 signal line 'The pressure signal lines 42 and 44 are attached to the wire by the degree of extension 099107997 Form No. A0101 Page 37 / Total 100 Page 0993254534-0 201040808. For example, if the touch panel of the present invention is applied to a 22-inch type LCD display device in which the unit pixel has a resolution of 1 366*768, the capacitive touch cell 31 is configured to have a resolution of 1 36*76. And the pressure touch cell 70 is configured at a resolution of 1366*768. In addition, if the signal line of the touch panel and the signal line of the display device are wired with the same rule, the touch panel and the display device are configured such that the touch panel and the signal line of the display device are both Positioned on an equal vertical line, the phenomenon of moiré caused by interference between the signal lines in the same direction of the display device and the touch panel can be prevented as another example of preventing the phenomenon of rubbing, like the third As shown in the drawing, the diffusion plate 90 is further disposed between the second substrate 60 and the display device 20. If the diffusion board 90 is disposed on the lower portion of the second substrate 60, the dimming phenomenon can be performed by using the signal line of the touch panel and the signal line of the display device on the equal line. The diffusing effect of the diffusing plate 90 is prevented. As another example of preventing the phenomenon of moiré, although not shown, the first capacitive signal line 32, the second capacitive signal line 34, the third capacitive signal line 36, the first pressure type Both the signal line 42 and the second pressure signal line 44 are arranged in a diagonal direction and are fitted with wires. The signal line, for example, the gate line and the data line of the display device 20 are conventionally arranged in all directions, that is, vertically and horizontally. Therefore, if the signal line of the touch panel is arranged in a diagonal direction, the touch panel and the signal lines of the display device traverse each other, thereby greatly reducing signal interference, thereby preventing the moiré phenomenon. Various modifications and variations of the composite input mode touch panel according to the present invention 099107997 Form No. A0101 Page 38 of 100 0993254534-0 The description will be as follows. Referring to Fig. 7, as a charging unit for charging the two conductive electrodes 46 and 48 of the pressure touch cell 70, the transparent conductive layer 62 is formed on the lower surface of the first substrate 60. Incidentally, if the transparent conductive layer 62 is formed on the entire lower surface of the second substrate 6'' as not shown in Fig. 7, the transparency of the touch panel may be lowered. Therefore, in order to improve the transparency of the touch panel, the transparent conductive layer 62 is preferably formed to cover at least the pressure touch cell 7. In this example, the transparent conductive layer 62 is only sufficient with a minimum local area. The ground is coated to charge the two conductive pads 46 and 48 corresponding to the pressure touch cell 70. However, if the transparent conductive layer β2 is formed too locally, the process of the touch panel may be more complicated. Accordingly, the present invention provides a method of simplifying the touch panel process and forming the pressure touch cell 70 and the transparent conductive layer 62. Figures 10 through 12 show examples in which the transparent conductive layer is divided and formed in the present invention. The capacitive touch cell 31 is configured in a 4*4 solution, and in each capacitive touch cell 31, the pressure touch cell 7 is configured in a 2*2 resolution. Figures 10 through 12 show the structure of the pressure-triggering cell 70 in this invention, respectively. Here, the structure of the capacitive touch cell 31 is not shown by green' and only the area of the capacitive touch cell 31 has been indicated in the lattice pattern. In addition, the pressure touch cell 7 is conceptually renewed, wherein two conductive pads 46 and 48 are depicted, and a transparent conductive layer 62 is formed over the two conductive turns 46 and 48. Referring to Fig. 10, the two conductive pads 46 of the pressure touch cell 7A and 48 are arranged in an equal oblique direction. The transparent conductive layer 62 is formed in a diagonal direction intersecting the two conductive pads 46 and 48. Therefore, if Form No. A0101 Page 39/Total Page 201040808 is reduced as described above. Therefore, the pressure touch cell 70 and the transparent conductive layer 62 are reliably protected, and the area on which the transparent conductive layer 62 is formed may be large, although the transparent conductive layer 62 is not accurately verified. The conductive pads 46 and 48 are configured by the transparent conductive layer 62&|, and the pressure signal lines can be arranged obliquely and can prevent the phenomenon of moiré. Referring to Fig. 11, it can be seen that the respective oblique lines of the transparent conductive layer 62 which are divided and formed in a diagonal direction are partially interrupted. The transparent conductive layer 62 in the form of a diagonal line can be completed in a simple procedure in which the pressure touch cell 70 can be divided in each area.

Further, referring to the embodiment of the humiliation shown in Fig. 12, it can be seen that the transparent conductive layer 62 has been divided and formed in each unit of the touch cell. If the transparent conductive layer 62 is divided and formed in each unit of touch cells as described above, the process can be even more complicated, but the transparency of the touch panel can be greatly improved. First, it is possible to obtain an effect of better insulating the force touch cell 70 with each other. Because of this, the touch wheel in each of the pressure touch cells 70 can be independently: 瑝, to thereby enable the multi-touch input.

Meanwhile, as described above, when the two conductive pads 46 and 48 of the pressure touch cell 7 are formed on respectively different substrates, and the bending occurs on the substrate, the two conductive pads 46 and 48 They are configured to contact each other to be then charged. In this embodiment, only one conductive pad is formed in each of the pressure touch cells 7 of the first substrate 3, and the other conductive pads and the transparent conduction of the first to the 12th views are shown. Layer 62 is formed on the 5 second substrate. According to a preferred embodiment of the present invention, the first substrate 30 is composed of a glass substrate. This is because the signal line is mounted on the wire, and the capacitor is mounted. 099107997 0993254534-0 Form No. Α0101 Page 40/Total 1〇〇 Page 201040808

The switching element 40, the touchpad 50, and the two conductive pads 46 and 48, and the program for connecting the signal lines to the respective ports are simply executed in the same manner as the display device 2 〇 process. If all of the components are disposed on the first substrate 30, as in the example of the specific embodiment, only the transparent conductive layer 62 may be formed on the second substrate 60. Therefore, the relative burden of the mounting component on the second substrate disappears, so that the second substrate can be fabricated using a film material of excellent flexibility. However, there is a problem that the film substrate is mild in view of surface strength, and is easily scratched by a sharp object such as a pen. Meanwhile, if the second substrate 60 is formed of a glass substrate, it is difficult to prove flexibility. If the glass substrate is made too thin, although the bendability is improved, there is a problem that the glass substrate is weak in impact. 〒: The specific embodiment of Fig. 13 shows an example of solving the above problem. That is, in the example in which the glass substrate is selected as the second substrate 60, the specific embodiment of FIG. 13 provides a method of stably charging the two conductive pads 46 and 48 of the pressure touch cell 7? At the same time, the glass substrate is not made too thin.

...: 丨::'' Referring to the cross-sectional view of Fig. 13, no transparent conductive layer is formed on the lower surface of the second substrate 60, but other elements are the same as those of the cross-sectional view of Fig. 7. A plurality of charging spacers 25c are provided on the lower surface of the second substrate 60 instead of the transparent conductive layer. The charging spacers 25c are patterned as shown, so that one end of each of the charging spacers 25c can be fixed on the lower surface of the second substrate 60. ITO or the like is coated on the other end of the respective charging spacers 25c to thereby form the conductive layer 65' and the conductive layer 65 is disposed to be in the each of the pressure touch cells 70 and the two conductive pads 46. And 48 apart. More preferably, the plurality of charging spacers 25c are mounted 099107997 Form No. A0101 Page 41/100 pages 0993254534-0 201040808 is set to correspond to the unit pressure type touch cell 70. Fig. 14 shows an example in which the pressure touch input takes place on the second substrate in the embodiment of Fig. 13. Referring to Fig. 14, as illustrated, when the second substrate 6 is depressed by the finger 26, the bending occurs on the second substrate 60. In this example, the conductive layer surrounding the end of the spacer 25c. 65 the two conductive pads 46 and 48 are charged. Therefore, even if the second substrate 60 is gently bent, the two conductive pads 46 and 48 of the pressure touch cell 70 can be stably charged. This means that when the second substrate 60 is composed of a glass substrate, the glass substrate does not need to be extruded or etched too thin" when the charging spacer 25c is used to charge the two conductions of the pressure touch cell 70. At the time of the pads 46 and 48, the position at which the charging stand 25c is installed becomes a very important factor. However, the specific embodiment of Fig. 15 shows that the two conductive pads 46 and 48 are more stably charged, even when the specific embodiment of Fig. 13 is applied, the charging spacer 25C is not accurately Positioning. In the embodiment of Fig. 15, the first conductive pad 46 and the second conductive pad 48 are formed in a non-uniform shape, wherein the concave portion 52 and the convex portion 54 are respectively connected: readably formed. The first conductive guide 46 and the second conductive pad 48 are configured to be in mesh with each other while the concave portion 52 and the convex portion 54 maintain a predetermined interval at each of the pressure touch cells 70 t. Therefore, as illustrated, even if the charging spacer 25c is disposed in the upper portion of the two conductive pads 46 and 48, the two conductive pads 46 and 48 can be stably charged. The charging mechanism for charging the two conductive pads 46 and 48 of the pressure touch cell 70 has been described in the previous embodiments. That is, 099107997 forms the transparent conductive layer 62 on the entire surface of the lower surface of the second substrate 60 on the entire surface of the A0101, and the two conductive pads 46 and 48 thus charged. The example has been described with reference to the cross-sectional view of Fig. 7. In addition, the transparent conductive layer 62 is divided and opposed to the example formed by the pressure touch cell 70, and the two conductive pads 46 and 48 and the transparent conductive layer 62 are traversed with each other and arranged in a diagonal direction. Examples have been described with reference to Figures 10 to 12. Further, an example of charging the two conductive pads 46 and 48 using the charging spacer 25c instead of forming the transparent conductive layer on the second substrate 60 has been described with reference to Figs. These specific embodiments are only specific embodiments of the invention. In the example of the touch panel according to the invention, the two conductive pads 46 and 48 of the pressure touch cell 70 can be charged differently than described above. For example, although not shown in the drawings, the capacitive touch cell 31 can be mounted on the first substrate 30, and the pressure touch cell 70 can be mounted on the second substrate 60. on. If the touch pad 50 of the capacitive touch cell 31 is disposed to charge the two conductive pads 46 and 48 of the pressure touch cell 70, the two touch cells 31 are The touch pads 50 of the capacitive touch cells 31 can be charged with respect to the pressure touch input without using the transparent conductive layer 62 and the charging spacers 25c. As another example, the first pressure signal line 42 and the first conductive pad 46 are formed on the first substrate 30, and the second pressure signal line 44 and the second conductive pad 48 are formed on the first substrate 30. On the second substrate 60. In addition, the first conductive pad 46 and the second conductive pad 48 are in contact with each other when a pressure touch input occurs. As described above, the two conductive pads 46 and 48 of the pressure touch cell 70 can be charged with respect to the pressure touch input by various charging mechanisms. 099107997 Form No. A0101 Page 43 of 100 0993254534-0 201040808 In the following, a specific embodiment for recognizing a multi-touch operation will be described using a touch panel according to the present invention. The touch panel according to the present invention includes the capacitive touch cell 31 and the pressure touch cell 70 having different input modes, respectively. Here, since the capacitive switching element 40 is mounted in the capacitive touch cell 31, the input/output from each touch cell and the signal output to each touch cell can be switched using the capacitive switch. The component 40 is intercepted, and the capacitive switching element 40 enables the capacitive touch cell 31 to recognize the multi-touch input. However, the basic structure of the pressure touch cell 70 makes it difficult to recognize multi-touch operations. For example, in the example in which the transparent conductive layer 62 is formed on the entire lower surface of the second substrate 60, if the touch input occurs at several points in the pressure touch cell 70, a plurality of pressures The touch cell 70 is electrically connected by the transparent conductive layer 62, and thus an error occurs when the touch signal is obtained. An example of dividing and forming the transparent conductive layer 62 in each unit pressure touch cell 70, and an example of charging the pressure touch cell 70 using the charging spacer 25c in the above specific embodiment, enables The multi-touch recognition is as described above without causing any errors. However, in this case, for example, an example in which the touch panel is applied to a small-sized display device such as a mobile phone LCD screen, it is difficult to divide and form the transparent conductive layer 62 in each of the pressure touch cells 70, Or the charging spacer 25c is installed. Accordingly, the present invention provides a method of more stably recognizing a multi-touch operation in the pressure touch cell 70. Referring to Fig. 16, each of the pressure touch cells 70 further includes a pressure switching element 41 disposed between the second pressure signal line 44 and the second conductive pad 48, as compared to the schematic view of Fig. 4. The pressure switching element 41 performs connection of the pressure signal line and any of the pressure touch cells 70. 099107997 Form No. A0101 Page 44/100 page 0993254534-0 201040808 Switching operation of the conductive pad. Unlike the specific embodiment of Fig. 16, the pressure switching element 41 can be disposed between the first pressure signal line 42 and the first conductive pad 46 in each of the pressure touch cells 70. In addition, a plurality of pressure type switching elements 41 may be disposed between the first pressure type signal line 42 and the first conductive pad 46 as the pressure type first switching element 41a, and the pressure type second switching element 4 lb An example is provided between the second pressure type signal line 44 and the second conductive pad 48. Various switching elements can be used as the pressure switching element 41. For example, the pressure switching element can be configured to prevent position detection signal recirculation by using a diode. More preferably, however, the pressure switching element 41 is a three terminal switching element such as a TFT. The three-terminal switching element can be turned on/off with a pulse applied to its gate terminal to prevent signal backflow and stably intercept the signal. Furthermore, it is advantageous that the TFT is an element that has been verified in the process of the display device 20 (e.g., LCD or AMOLED). In the specific embodiment of FIG. 16, the input terminal of the pressure TFT through 1 is connected to the second conductive pad 48 in each of the pressure touch cells 70, and the output terminal thereof is connected to the second pressure signal. Line 44. A plurality of pressure-type auxiliary signal lines 49 are further disposed on the first substrate 30, and a gate terminal of the pressure type TFT 41 is connected to the pressure-type auxiliary signal line 49. The pressure auxiliary signal line 49 is connected to the drive 1C 81 and is controlled by the drive 1C 81. The drive 1C 81 continuously applies scan pulses to the pressure auxiliary signal line 49, respectively. According to this composition, when the gate signal applied to the pressure auxiliary signal line 49 is a turn-off signal, even if the first conductive pad 46 and the second conductive pad 48 are mutually mutually in the pressure touch cell 70 Charging, position detection 099107997 Form No. A0101 Page 45 / Total 100 Page 0993254534-0 201040808 The signal is not output via the second pressure signal line 44. That is, as long as the gate signal applied via the pressure auxiliary signal line 49 is an open signal, the pressure touch input can be effectively recognized. Therefore, the opening/closing operation of the pressure type TFT 41 is controlled in each of the pressure touch cells 70 to thereby enable the identification of the multi-touch input.

Fig. 17 depicts a specific embodiment of the reinforcing structure of the capacitive touch cell 31 in the embodiment of Fig. 16. In FIG. 16 , since the capacitive touch cell 31 is connected to the common first capacitive signal line 32 , the touch pad 50 in the lateral direction is also connected to the common first capacitive signal line 32 . . When the touch input occurs in any of the capacitive touch cells 31 in the structure, the touch input can affect another capacitive touch cell 31 connected to the common first capacitive signal line 32. This phenomenon can be solved by individually mounting the first capacitive signal lines in each of the capacitive unit touch cells 31. However, this method may result in a problem of reducing the transparency of the substrate due to the large number of capacitive first signal lines. Therefore, a more reliable solution is to electrically isolate the touch pad 50 of the capacitive touch cell 31 from the common first capacitive signal line 32, and FIG. 17 shows this embodiment. Referring to Fig. 17, in addition to the embodiment of Fig. 16, a capacitive auxiliary switching element 40a is connected between the first capacitive signal line 32 and the gate terminal of the capacitive TFT 40. When the TFT is used as the capacitive auxiliary switching element 40a, since the TFT typically has an RDS (on) resistance of about 1 ohm, the signal is intercepted between the touch pads 50. In addition, when a tap occurs, the RDS (on) resistor plays a role in determining the discharge constant of the voltage formed in the dummy capacitor between the touch pad 50 and the human body. The capacitive auxiliary switching element 40a can be configured by various switching elements as in the example of the pressure switching element 41, 099107997, Form No. A0101, page 46/100 pages 0993254534-0. Preferably, the capacitive auxiliary switching element 40a is formed by a three terminal switching element (e.g., tft). Further, an input terminal of the electric valley auxiliary TFT 40 is connected to the first capacitive signal line 32 in each of the capacitive touch cells 31, and an output terminal thereof is connected to a gate terminal of the capacitive TFT 40. A plurality of capacitive auxiliary signal lines 37 are further disposed on the first substrate 3A, and a gate terminal of the capacitive auxiliary TFT 40a is connected to the added capacitive auxiliary signal line 37. The capacitive auxiliary signal line 37 is also coupled to the drive ic 81 and is controlled by the drive 1C 81. The driver 1C 81 can continuously apply a scan pulse or a general turn-on voltage to the capacitive auxiliary signal line 37 » v : as a preferred embodiment of the composition 'when applied to the capacitive auxiliary signal line 37 When the gate signal is the off signal, the capacitive auxiliary tft 40a is turned off 'to detect the pressure touch signal at this point in time. When the gate signal applied to the pressure auxiliary signal line 49 is a turn-off signal, the pressure switching element 41 is turned off to thereby detect the capacitive touch signal at this point in time. Therefore, since the price measurement time of the capacitive touch cell 31 is different from the detection time of the pressure touch cell 70, the capacitive touch cell 31 and the pressure touch cell can be stably prevented. Yuan 7〇 influence each other. Fig. 18 is a waveform diagram showing an example of recognizing a touch signal in the specific embodiment of Fig. 17. Referring to Figure 18, the operation of the specific embodiment will be described as follows. In the section depicted in the lower part of Figure 18, "area 丨" is the detection pressure.

Whether the touch cell 70 is touched or not, the "area 2" is the area of the detection form number A0101 page 47/total 1〇〇I 201040808 whether the capacitive touch cell 31 is touched, and "Area 3" and "Area 4" are the overlapping sections of the "Area 1" and the "Area 2", respectively. The signals depicted in the waveform diagram of Fig. 18 will be described as follows. The signal applied to the first capacitive signal line 32 is DCn, the signal applied to the second capacitive signal line 34 is AUXn, and the signal input to the third capacitive signal line 36 is SCn, applied to the capacitive type. The gate signal of the auxiliary signal line 37 is GCn, the signal applied to the first pressure signal line 42 is DPn, the signal input to the second pressure signal line 44 is SPn, and is applied to the pressure auxiliary signal line. The gate signal of 49 is GPn. In Fig. 18, it is desirable that the signal of "Region 1" of the touch-sensitive touch input is not generated when the signal of "Region 2" of the capacitive touch input is detected to continue. That is, it is desirable that the signal DPn applied to the first pressure signal line 42 is a high impedance signal or a floating signal in the "area 2" and the "area 4". In Fig. 18, in the "Zone 2" and "Zone 4", the signal applied to the first pressure signal line 42 is traced as if it were a low signal and it is in a high-rent or floating section. . This is because the pressure touch input occurs in an example where 5 §fl is said to be continuously applied in the "area 2", and therefore it is difficult to be in the touch due to the electric field formed by the debt measurement voltage. A static capacitance is formed between the pad 50 and the human body, and the detection voltage corresponds to the pressure touch input and is applied to the transparent conductive layer of the second substrate 6 . Similarly, it is desirable that the touch pad 5 of the capacitive touch cell 31 is in a high impedance or floating section in the "area 1", and the "area i" is a pressure touch input detection. Measurement section. This is because the detection voltage is applied to the transparent conductive layer 62 of the second substrate 6 by the pressure touch input in the "area 1", but if the capacitive touch cell 31 functions, the 099107997 form The number is deleted. Page 48/100 pages 201040808 The transparent conductive layer 62 of the capacitive touch cell 31 and the touch pad 5 are in contact with each other to thereby generate an overcurrent due to an electrical short. That is to say, the signal input/output from the side capacitive touch cell 31 and the output to the capacitive touch cell 31 are intercepted in the "area". Therefore, even if the transparent conductive layer 62 of the first substrate 60 and the touch pad 5 are in contact with each other, current consumption is not generated. In addition, the noise of the DPn is reduced, the noise of the DPn is the detection voltage of the pressure touch input, and the Dpn can act like a stable signal. As depicted, if the signal used as the gate voltage of the capacitive auxiliary TFT 40a is turned off in the "region 1", the touch pad 5Q of the capacitive touch cell 31 is determined. In the state of the return impedance, there is no state of applying the signal to the _ capacitive signal line 32 2 signal DCn and the state of the signal AUXn applied to the second electric signal line 34 in the r region ^. According to FIG. 18, the touch position detector 80 provides the pressure auxiliary signal line 49 in the area L and the area 3 and the continuous scan pulse of the first pressure type signal 42 respectively. And "Zone 3" is the Russian test section of the 力 I force touch input. As shown, in the example where the gate signals in any of the plurality of gate signals GPn are turned on, the remaining 4 gate numbers remain off. If the signal is turned on, the other gate signals GP1, GP2, and Gp4 are turned off. In the example in which the signal (10) is turned on, the TFT turn-on voltage is supplied to the gate terminal of the mystery STFT 41 connected to the third pressure type auxiliary signal line 49. In this example, the TFTs are respectively supplied to the gate terminals of the Mi-type TFT 41 connected to the other pressure-type auxiliary signal lines 49. As an example, the TFT turn-on voltage of GPn is 12V to 18v, and (4) the pull-off voltage is _5V to -1 ον. Applied to the first pressure type signal line 42 for the pressure-type beautiful form number Α0101, page 49/total 1 page 〇9! 201040808 TFT 41 stable switching action DPn use ratio corresponds to the pressure type TFT 41 gate signal (jpn is lower than a TFT threshold voltage or more voltage. As an example, 5V is used as DPn. See Fig. 18, the touch position detector 80 provides "Zone 2" and The "area 4" capacitive auxiliary signal line 37 and the first capacitive signal line 32 continuously scan pulses, and the "area 2" and the "area 4" are detection sections of the capacitive touch input. The gate signal GCn can be simultaneously applied to the plurality of capacitive auxiliary signal lines 37. However, when a DCn is applied to the capacitive auxiliary signal line 37, in order to prevent mutual interference of the SCn, the SCn is from the capacitor. The signal output by the touch cell 31, the other DCn remains off regardless of the gate signal GCn. For example, when DC1- is applied to the capacitive auxiliary signal line 37, even if GC2 is applied to the capacitive Auxiliary signal line 37 'DC2 maintained Therefore, the capacitive TFT 40 connected to DC2 becomes in a closed state. As an example, the TFT turn-on voltage of GCn is 12V to 18V, and the TFT turn-off voltage of GCn is -5V to -10V. The DCn uses a TFT network voltage or more lower than the GCn corresponding to the gate signal of the capacitive TFT, and the DCn is an input signal of the capacitive auxiliary TFT 40a. As an example, 12V is used. In addition, it is desirable that AUXn uses a TFT threshold voltage or more lower than DCn, and the AUXn is applied to the second capacitive signal line as an input signal of the capacitive TFT 40. 34. The DCn is the gate signal of the capacitive TFT 40. As an example, 5V is used as the AUXn. As depicted, the turn-on voltage applied as the GCn applied to the capacitive touch cell 31 is applied. After detecting the capacitive touch input, sufficient observation time is provided between the continuous signals. This is used to measure the signal emitted from the virtual 099107997 form number A0101 page 50 / total 1 page 099 201040808 capacitor Adequate (four), near ' Virtual Capacitor HΑ# The connection of the human body is intended to be generated by the finger 26 and the touch. For the stabilization of the signal, and the prevention of the signal: there is a pause period between the signals. The process of obtaining the touch signal by the capacitive control cell 31 will be described as follows. As for the output waveform core in the female capacitive touch cell 31, the signal is in the signal because of the wire resistance and the parasitic capacitance. The third capacitive signal line 36 to which the input is applied is curved in a section where the waveform rises from a high level to a low level and a section where the waveform falls from a low level to a high level. In the example where the touch does not occur between the human body and the touch panel 5 'signal transmission is terminated by GCn' and the capacitive m lion gate voltage drops sharply shortly after changing to the observation phase, assuming SCn drops The time taken to the level of 5〇% is "η". However, compared to the peach signal GCn and the input signals DCn and Αυχη, the time delay occurs at the output of the simple SCn, and the secret map + has been ignored in the

The transient response characteristic at the time point when the touch between the human body and the touchpad p occurs. If the touch input occurs due to the proximity of the capacitive touch cell 31 at the upper end of the left hand side of FIG. 17 at a specific point in time, the electrostatic capacitance is formed on the finger 26 of the human body and the capacitive touch. Corresponding points between the touch pads 50 of the cells 31 are appropriate. As seen in the waveform diagram of Figure 18, if the touch has occurred at the time of "Zone 2", the voltage charged by the electrostatic capacitor will be discharged at the observation time mode of "Area 2", that is, when DC1 becomes Low level of time. Therefore, the gate voltage of the capacitive TFT 40 is slowly lowered, and the input of the capacitive type tft 40 is 099107997 Form No. A0101 Page 51 of 1 Page 0993254534-0 201040808

The waveform shows the inherent waveform, as seen from the waveform of SC1, TFT

The gate voltage characteristics are reflected on the inherent waveform. Here, it is assumed that the time taken for the SCI waveform to fall to the 50% level is "T2", and T2 is much larger than T1. Therefore, the touch position detector 80 detects the time when the SCn waveform drops to a predetermined level or the voltage that has decreased at a predetermined time point, and the SCn waveform is input through the third capacitive signal line 36 at the observation time. Signal. A timer can be used to measure the fall time T2 delayed by the static capacitance formed between the finger of the human body and the touch pad 5?. The reference voltage can be used to determine the amount of voltage that has dropped at a predetermined point in time. The reference voltage can be generated by a rate provider (not shown) mounted in the touch position detector 80. Further, when the capacitive touch input does not occur, the fall time of the rise of the inherent output waveform SCn and the rise time of the fall of the inherent output waveform SCn can be used as the reference time of the timer. However, the reference time of the timer can be changed by the wire of the resistor of the line 4 or the parasitic capacitor, and the reference time of the timer is between the touch panel and the display device 20 The variable time that changes in combination with the state. In other words, the reference time of the timer may depend on the state in which the touch panel is manufactured. This means that it takes a lot of time and effort to accurately measure the reference time, and such reference time may sometimes be measured by discs. Fig. 19 shows a specific embodiment of a touch panel that solves the above problems. Fig. 19 shows a frame ho of a hand-held device (e.g., a mobile phone) in which a touch panel according to the present invention is mounted at a lower portion of the frame 11''. As depicted, a plurality of reference time measurement cells 120 can be formed in conjunction with 099107997 Form Number A0101 page 52/100 pages 0993254534-0 201040808 in the touch panel of the lower portion of the frame 110 of the handheld device . Fig. 19 shows a state in which a plurality of reference time measuring cells 120 formed in the touch panel are projected to the frame 110. It is desirable that the reference time measuring cell 120 can be formed in the inactive area of the first substrate 30 or the second substrate, but they can be formed in the active area of the first substrate 3 or the second substrate 6 . At the same time, the reference time measuring cell 12〇 has the same structure as the capacitive touch cell 31, but the touch pad 5〇 is not separately installed from the reference time measuring cell 120, so that the touch is not reversed. wide. The image time measuring cell 120 finds the waveform characteristic by the wire resistance in the capacitive touch cell 31 and the difference in the presence and size of the parasitic capacitance punch. That is to say, the reference time measuring cell 12 finds a waveform characteristic in which the touch pad 50 does not involve the state of signal detection in the capacitive touch cell 31. In other words, the touchpad 50 is ignored from the reference time measuring cell 120, respectively. This reference time measuring cell 120 is used as follows. The reference time measuring cell 120 has the same structure as the capacitive touch cell 31 except for the touch pad. The signal is applied to the reference time measuring cell 12〇, and then determined in the same manner as the touch signal is obtained in the capacitive touch cell 31. In the touch panel manufacturing step, the cell is measured from the reference time. Yuan 120 output of the message. T1, which is not in the waveform diagram of Fig. 18, is measured from the signal output from the reference time measuring cell 120. The measured τ 1 is used to detect the touch input in the capacitive touch cell 31, respectively. Referring to the example of Fig. 19, the reference time measuring cells 120 are respectively disposed in the lower regions of the touch panel at appropriate points of PI, P2, and P3 of the frame 110 of the handheld device. The reference time at the appropriate point of P1 measured in the reference time measuring cell 120 is used as the obtaining bit in "Zone 099107997 Form No. A0101 Page 53 / Total 1 Page 0993254534-0 201040808 Domain A" The reference time of the touch signal of the capacitive touch cell 31. Similarly, the reference time measuring cell 120 of the appropriate points of P2 and P3 respectively provides a reference time for obtaining the touch signal of the capacitive touch cell 31 located in "area B and C". The reference time measured at the appropriate PI, P2, and P3 points, respectively, may vary due to the wire resistance or the difference in the parasitic capacitor. Therefore, the detection sensitivity of the capacitive touch input can be improved by measuring the plurality of reference time cells 120. Since there are many reference time measurements for the cell 120, the sensitivity of the capacitive touch input can be further improved. At the same time, it is possible to obtain respective touch signals from the capacitive touch cells 31 in a different manner than the method described with reference to the waveform diagram of Fig. 18. For example, in a state where the signal DPn applied to the pressure touch cell 70 is turned off at a specific time point, that is, in a state in which all operations of the pressure touch cell 70 are turned off, all capacitive types are The gate signal GCn of the TFT 40 is simultaneously turned on. Then, charging of the dummy capacitor formed between the human body and the touchpad 50 is induced, and thereafter the signals are continuously transmitted to the second capacitive signal line 34, respectively, so as to observe the respective outputs to the third The waveform output of the capacitive signal line 36. In addition, those skilled in the art can use the technical spirit and concept of the invention to detect capacitive touch inputs in various ways. Compared to the specific embodiment of Fig. 17, Fig. 20 shows an example in which the pressure touch cells 70 are configured differently. This embodiment of Fig. 20 shows that the pressure TFTs 41 are respectively disposed between the first pressure type signal line 42 and the first conductive pad 46 in the pressure touch cell 70. The gate terminal of the pressure TFT 41 is connected to the pressure auxiliary signal line 49, and the input terminal and the output terminal of the pressure TFT 41 are respectively connected to the first voltage 099107997 Form No. A0101 Page 54 / Total 100 Page 0993254534- 0 Force sfl line 42 and the first conductive pad 46. Therefore, if the pressure type TFT 41 respectively performs an opening operation to connect the first pressure signal line 42 and the first conductive pad 46, the signal applied to a first pressure type signal line 42 due to static electricity or external disturbance can be prevented. The other first pressure signal line 42 is affected. However, in the example of the specific embodiment of Fig. 20, each of the pressure sensitive cells 70 performs a selection operation to connect the first pressure signal line 42. The position detecting signal of the second substrate can be applied to the climbing conductor 48 of any one of the pressure touch cells 7 via the transparent conductive layer 62 at the time when the pressure touch cell 70 is charged. The specific embodiment of Fig. 21 shows that τ enables a stable embodiment of multi-touch recognition by more completely isolating the pressure-sensitive touch cell 7 regardless of the presence of the transparent conductive layer 62. Referring to Fig. 21, each of the pressure type control cells 70 includes two pressure type switching elements 41a and 41b. The pressure type first switching element 41 a is disposed between the first pressure type signal line 42 and the first conductive pad 46 , and the pressure type second switching element 41 b is disposed on the second pressure type signal line 44 . And between the second conductive pads 48. Preferably, the pressure type first switching element 41a and the pressure type second switching element 41b are each formed of a TFT, and the gate terminals of the two TFTs are commonly connected to the pressure auxiliary signal line 49, respectively. With this configuration, in the example where the gate signal applied to the pressure auxiliary signal line 49 is turned off, the pressure touch cell 70 on the associated line completely separates the two conductive pads 46 and 48 from The signal line is isolated. Therefore, the signal can be completely prevented from flowing back through the two conductive pads 46 and 48 contacting the transparent conductive layer 62. In addition, failures occurring in the first pressure signal line 42 due to static electricity or external disturbances can be prevented. However, Form No. A0101, page 55/100 pages 201040808 In the specific embodiment of Fig. 21, it results in a burden of mounting two TFTs in each of the pressure touch cells 70. Fig. 22 shows an example of a capacitive touch cell 31 configured to have a different shape from that of Fig. 17. Referring to Fig. 22, in addition to the specific embodiment of Fig. 17, a plurality of capacitive first auxiliary signal lines 37a and a plurality of capacitive second auxiliary signal lines 37b are disposed on the first substrate 30. A capacitive auxiliary switching element 40a is provided in each of the capacitive touch cells 31, and the capacitive auxiliary switching element 40a is formed of a TFT in the same manner as the embodiment of Fig. 17. An input terminal of the capacitive auxiliary TFT 40a is connected to the first capacitive signal line 32, an output terminal thereof is connected to a gate terminal of the capacitive TFT 40, and a gate terminal thereof is connected to the capacitive first auxiliary signal line 3 7a. In addition to this composition, the embodiment of Fig. 22 further includes a capacitor 55 in each of the capacitive touch cells 31. As depicted, a capacitor 55 is coupled between the gate terminal of the capacitive switching element 40 and the capacitive second auxiliary signal line 37b in each of the capacitive touch cells 31. Fig. 23 is a waveform diagram showing an example of recognizing a touch signal in the specific embodiment of Fig. 22. The waveform diagram of Fig. 23 is similar to the waveform diagram of Fig. 18. The operation of obtaining the touch signal in the pressure touch cell 70 and the waveform correspond to the operation and waveform of Fig. 18. Therefore, a basic explanation about the operation of the pressure type touch cell 70 will be omitted in the waveform diagram of Fig. 23. As a specific embodiment for obtaining the capacitive touch signal, the turn-on voltage of the GCn is 18V, and the high level potential of the DCn is suitably about 12V as the turn-on voltage for turning on the capacitive TFT 40. According to a particular embodiment of the invention, the second capacitive auxiliary signal line AUX2-n connected to the other end of the capacitor 55 can be made to have a zero (0) potential as a view to observe 099107997 Form Number Α0101 Page 56 / A total of 100 pages 0993254534-0 201040808 signal line. In the example of the specific embodiment of Fig. 22, an additional capacitor 55 is further provided in each of the capacitive touch cells 31 as compared with the specific embodiment of Fig. 17. This additional capacitor 55 combines with a dummy capacitor formed between the body and the touchpad 50 and acts to delay the time it takes for the SCn signal to fall. As can be seen by the SCI signal in "Area 4", if no capacitive touch input occurs, the waveform of the signal output to the third capacitive signal line 36 decreases with a falling time of T1. If the finger 26 (as shown in Fig. 14) is adjacent to any of the capacitive touch cells 31, the dummy capacitor is formed on the human body and the touchpad 50. The dummy capacitor and the additional capacitor 55 are like the SCI in the "Zone 2" to thereby extend the fall time to T2. Therefore, the touch position detector 80 detects the time difference between T1 and T2 to thereby obtain the touch signal. In the meantime, the specific embodiment of Fig. 22 can obtain the touch signal from the capacitive touch cell 31 in various different manners. For example, by a method, charging of the capacitor 55 can be done before the touch input occurs. Therefore, if the tap input occurs after the charging of the capacitor 55 has been completed, the charge charged in the capacitor 55 is shared with the dummy capacitor, that is, the capacitor 55 performs a charge sharing operation. Therefore, it can be seen that the falling time of the discharge signal output from the capacitor 55 has a T4 which is shorter than T1 as seen from the SC2 signal in the "Area 4". That is, in the example of the method of charging the capacitor 55 in advance and then detecting the touch input, the time taken for the output waveform SCn to fall by the sharing of the charge between the capacitor 55 and the dummy capacitor becomes It is shorter than the reference time. Therefore, the touch position 099107997 Form number A0101 Page 57/100 pages 0993254534-0 201040808 The detector 80 detects the time difference between T1 and T4 to obtain the touch signal. Therefore, according to the embodiment of Fig. 22, the electrostatic capacitance of the added capacitor 55 can be controlled in various aspects to thereby control the voltage applied to the gate of the capacitive TFT 40. Therefore, the capacitance of the capacitor 55 can be appropriately selected to thereby select the falling slope of the SCn signal when touch is achieved. Therefore, the capacitive touch can be stably detected. Fig. 24 shows an example in which some of the capacitive touch cells 31 are individually mounted. Referring to Fig. 24, three capacitive touch cells 31 located at the lower portion of Fig. 24 are formed without being overlapped with the pressure touch cells 70, respectively, but formed in separate regions. Therefore, in the example in which the capacitive touch cells 31 are separately formed, the second substrate 60 can be removed from the associated position. This is because the capacitive touch cell 31 detects a light touch input, such as a body contact or proximity, and further, all of the components of the capacitive touch cell 31 are mounted in a single substrate. Therefore, if the second substrate 60 is removed from the area where only the capacitive touch cell 31 has been formed, the interval "d" between the finger 26 and the touch pad 50 becomes small, thereby providing an increased capacitance. The effect of touch signal sensitivity. However, even in this example, the capacitive touch cell 31 needs to be protected by applying a transparent insulating material to the surface of each of the capacitive touch cells 31. However, if the capacitive touch cell 31 is mounted in the second substrate 60, as shown in FIG. 24, the first substrate 30 does not need to be in the region from which the capacitive touch cell 31 is formed. The removal, and further, since the capacitive touch cell 31 is formed in the lower surface of the second substrate 60, the transparent insulating material needs to be coated on the capacitive touch cell 31. However, the interval "d" between the finger 26 and the touchpad 50 is shortened to 099107997 Form No. A0101 Page 58 / Total 100 Page 0993254534-0 201040808 Therefore, the effect of increasing the sensitivity of the capacitive touch signal is provided. Meanwhile, unlike the specific embodiment of Fig. 24, only the pressure type touch cell 70 can be mounted in some areas of the touch panel. Therefore, in the case where only the area where the pressure touch cell 70 has been mounted as described above, the association with the touch pad 50 may be disregarded in the process of forming the two conductive pads 46 and 48. Therefore, the pressure touch cell 70 can be integrated with high resolution. That is to say, the touch panel according to the invention can be designed with various modifications, that is, in the example of increasing the touch sensitivity of the capacitive touch cell 31, or in some areas of the touch panel. In some examples where high-resolution touch input is required, only the capacitive touch cell 31 or only the pressure touch cell 70 is formed in some areas of the touch panel. Figures 25 through 28 show a specific embodiment of forming a pressure touch cell 70 in a different form. These embodiments show various methods of detecting touch input in the pressure touch cell 70 by a change in state of the pressure switching element 41. These specific embodiments differ somewhat from the previously described embodiments in terms of circuit composition and operational mechanism compared to the elements of the above-described pressure-sensitive touch cell 70. Referring to Fig. 25, a plurality of pressure type auxiliary signal lines 49 are further disposed on the first substrate 30. The respective pressure touch cells 70 have a three-terminal pressure switching element 41 having input and output terminals connected to a first pressure signal line 42 and a second pressure signal line 44, respectively. One of the two conductive pads 46 and 48 is connected to the gate terminal of the pressure switching element 41 in each of the pressure touch cells 70, and the other conductive pad is connected to the pressure auxiliary signal line 49. In the depicted example, the 099107997 Form No. A0101, page 59/100 pages, 0993254534-0 201040808, a conductive whole 46 is connected to the gate terminal of the dust-type switching element 41, and the second conductive pad 48 is connected. To the pressure auxiliary signal line 49. In this embodiment, the pressure switching element 41 is preferably a TFT. The pressure auxiliary signal line 49 is a scanning signal line for turning on/off the pressure type TFT 41, respectively. The turn-on voltage is applied to the signal line for detecting the touch signal, and the turn-off voltage is applied to the other signal line. Here, as an example, the general off state voltage applied to the pressure auxiliary signal line 49 is -5V to -10V, and the turn-on voltage is 12V to 18V. According to this configuration, if the touch input occurs in a specific pressure type touch cell 70 in a state where all of the pressure type TFTs 41 have been turned off, when a scan pulse is applied to the corresponding pressure touch cell 70 At the time point, the associated pressure TFT 41 is turned on. In addition, the position detecting signal applied by the first pressure type signal line 42 is output to the second pressure type signal line 44 by the pressure type TFT 41. The touch position detector 80 detects the position detection signal and obtains the touch signal. Figs. 26 to 28 show the composition of the further signal intercepting switching element 41c in addition to the specific embodiment of Fig. 25. To better understand the present invention, only the circuit composition of a single pressure touch cell 70 has been depicted in this figure. The signal intercepting switching element 41c can be configured by a diode such as a switching element to prevent signal reflow and to intercept the signal, but is preferably formed by a TFT. As depicted, in each of the pressure touch cells 70, the signal intercepting switching element 41c is mounted in any one of the three terminals of the pressure TFT 41. Further, a plurality of signal intercepting gate signal lines 49c are further configured to turn on/off the signal intercepting switching element 41c in the first substrate 30. 099107997 Form No. A0101 Page 60 of 100 0993254534-0 201040808 In the embodiment of Fig. 26, the signal intercepting TFT 41c is mounted to the gate terminal of the pressure type TFT 41. Here, the gate terminal of the signal intercepting TFT 41c is connected to the signal intercepting gate signal line 49c, and the input and the wheel terminal of the signal intercepting TFT 41c are respectively connected to the second conductive pad 48 and the pressure TFT 41. Gate terminal. In the embodiment of Fig. 27, the signal intercepting TFT 41c is mounted to the wheel of the pressure type TFT 41; Here, the gate terminal of the signal intercepting TFT 41c is connected to the signal intercepting gate signal line 49c, and the input and output terminals of the signal blocking TFT 41c are respectively connected to the first pressure type signal line 52 and the pressure type Input terminal of the TFT 41. In the specific embodiment of Fig. 28, the signal intercepting TFT 41c is mounted to the output terminal of the pressure type TFT 41. Here, the gate terminal of the signal intercepting TFT 41c is connected to the signal intercepting gate signal line 49c, and the input and output terminals of the signal intercepting TFT 41c are respectively connected to the output terminal of the pressure TFT 41 and the second pressure type. Signal line 44. In the specific embodiment of Figures 26 to 28, the added signal intercepting TFT > 41c intercepts the signal reflow 'and prevents the interference of the signal in each of the pressure touch cells 70' only at the desired time. The pressure touch cell 70 is charged at a point. Therefore, it is possible to perform stable multi-touch input in the pressure touch cell 70. The invention has been described in terms of preferred embodiments. However, the present invention is not limited by the specific embodiments described above, and various modifications and variations may be made by those skilled in the art without departing from the spirit of the invention as defined by the appended claims.
