Description of the Invention: [Technical Field] [0001] The present invention relates to a touch panel placed on a display panel, and more particularly to a touch panel having high light transmittance and high response speed And there are no faults due to noise and environmental impact, and low cost, high yields, low probability of defective products and no Murray effect. [Prior Art 3

[0002] Generally, a touch panel is an input device attached to a display panel such as an LCD, a PDP, an OLED, an AMOLED, and a position sensor corresponding to a touch point by a finger or a pen. The touch panel is widely used for an individual. Devices, industrial devices, and DIDs (digital information devices are usurped. _ - The familiar touch panel is classified as a resistor, a type of light, etc.! Figure 1 shows a resistive touch panel. In Figure 1 The first substrate 3 and the second substrate 5 facing each other on the touch panel display device 1 apply transparent conductive layers 7 and 9 such as ITO (indium tin oxide) to the upper surface of the first substrate and the second substrate 5, respectively. The lower surface, the plurality of dummy materials are supplied to the upper surface of the first substrate 3, and the "not shown ^§# point is provided on the lower surface of the second surface of the second substrate. If the pen 17 contacts the second substrate 5', the second The substrate 5 is bent 'and the conductive layer 9 of the second substrate 5 contacts the conductive layer 7 of the first substrate 3, and then the voltage applied to the conductive layers 7, 9 is decreased by the resistance value of the corresponding resistance point 11' and the detected voltage The value is converted to a digital value by the AD converter 13 'this value is sent to the CPU 15 and the coordinate value of the touch point is obtained. The resistive touch panel is widely used because of its simple manufacture and low cost. However, the resistive touch panel has a disadvantage that the light transmittance is relatively low, because the conductive layers 7, 9 are applied to the first substrate 3 And the second substrate 5 ' 098137414 Form No. A0101 Page 3 of 32 0993044619-0 201027404 枭 Change the display device 1 which is inferior in quality due to low transmittance, and the detection of analog signal due to ''door delay' Converting the analog signal to a digital signal results in 'γ' and can't ignore the cost of a reliable AD converter. In addition, the key problem of the ## starting point panel is that it needs to be corrected to fix the array f' and if the correction is inaccurate, it will increase the detection. Measuring position error. is cz V shape

If the resistive touch panel is contacted by the pen 17, the second substrate 5 should be bent M, so the second substrate 5 is made of a high elastic film or it is made of frosted or frosted glass having a thickness of 2 mm. 3 mm. . If a film is used as the first substrate 5, since the transmittance of the film is lower than the transmittance of the glass, the transmission 令人 is unsatisfactory, and the film is easily damaged, which results in a low-quality claw device. · Second base of bismuth glass If glass is used as the second substrate 5, the method of manufacturing a uniformity of 0·2~〇. 3 mm glass sheet is difficult and the slab 5 is easily broken. If the size of the resistive touch panel is increased, maintaining the uniformity of ΙΤ0 becomes difficult. .1 ^ | g I , it is difficult, so it is difficult to achieve the resistance value of the 4 sides of the resistor. The resistive touch panel is almost impossible to use. The large-size optical per y fiber-optic touch panel includes the optical fiber of the form of the camera at the edge of the display device 1 and the contact position based on the image captured by the camera or the input signal from the infrared sensor. The touch panel is quite high in response speed and its size is not limited, so it is widely used in large-size display panels, but this type of touch panel is costly and accurately mounted to obtain accurate camera. Contact position values are very difficult, and they also require difficult zero adjustments, so accurate position detection is not easy. The infrared type touch panel includes a photoemitter and a photoreceiver on the display 098137414 Form No. A0101 Page 4 of 32 0993044619-0 201027404 The opposite side of the panel, and the break point due to contact is detected. However, under the ray of light, infrared rays from the sun can cause malfunctions and dust at the detection points can cause malfunctions.

[Advantages] According to the present invention, since a plurality of signal lines are formed longitudinally or laterally on the first substrate 40 or the second substrate 60, and a pair of conductive pads are branched from the signal line 098137414, Form No. A0101, Page 8 of 32 Forming a touch chamber, and obtaining a position signal by detecting contact of the conductive pads, the coated area of the transparent conductive layer such as IT〇 on the first substrate 40 or the second substrate 60 can be significantly reduced, so the light transmittance can be highly increased.

[Embodiment] [0004] 098137414 [Best Mode] Hereinafter, a preferred embodiment of the present invention will be described. First, the present invention relates to a touch panel 5 on a surface of a display panel such as an LCD, a PDP, an OLED, or an AMOLED. The position of the touch point corresponding to the contact point touched by the human or the pen, although the touch panel of the present invention is separated from the display panel, the example of the touch panel is a component of the touch panel; for example, the signal line, the driving 1C system and the display device For example, the gate line of the LCD or AMOLED, the data line, and the drive 1C are formed in the same or similar manner. Although their appearance may be _ ΐ i ® ® 4 similar to each other, their actual function. 1^, _ . . . ..:::. i.'-'·'i£fViii 5-="' Week 2 is the control surface according to the present invention ^ as shown, the first substrate 40 and The two substrates 6o are placed in display, and the first substrate 40 and the second substrate 60 are both made of transparent glass or film or other light transmissive material. Preferably, the first substrate 40 is made of glass, and the signal line is formed on the upper surface of the first substrate 40. Similar to the general display panel, the transmission driving signal 1C 71 for transmitting the position signal and the receiving driving 1C for receiving the position signal are COF. (Cladding film) or COG (glass flip chip) is mounted on the edge of the first substrate 40. In general, many components are mounted on the display panel and form number A0101 on the display panel. Page 10 of 32 〇ί 201027404 allows the space to be very narrow, but the touch panel according to the present invention is sufficient as long as it can be transmitted The drive 1C 71 applies the position signal and receives the position 彳g number via the receive drive 1C 72. Therefore, the drive ics 71, 72 can be integrated into one wafer. And the transmission drive 1C 接收 and the reception drive 1C 72 can be mounted on the second substrate 60, and the signal line can also be formed on the second substrate 6 0 0 reference 3, the first substrate 40 and the second substrate 6 By multiple intervals

The objects 25 are separated from each other, and the spacers 25 are made of an insulating material, and may be spherical spacers 25a that roll and contact between the first substrate 40 and the second substrate 60, or they may be loops f4 , one end is patterned and

A substrate is fixed to one substrate and the other and two types of spacers are as shown in FIG. 3, and the first signal line 44 is formed on the first substrate 40 by a different layer, and the first signal line 42 is The metal layer is insulated from the metal layer of the second signal line 44 by the insulating layer 33, and the transparent conductive layer 62 is formed on the second substrate 6〇4π|^|β€ΐΐΐαΙ

Fig. 4 shows that the flat first signal line 42 of the first substrate 40 is performed laterally and the first 彳 线 line is stepped on and over the first signal line 42. However, this is only a preferred example, and these signal lines 42, 44 do not necessarily have to cross each other. The first signal line 42 is coupled to the transmit drive 1C 71 and the transmit position signal, and the second signal line 44 is coupled to the receive drive 1C 72 and the receive position signal. The first conductive pad 46 is connected to the first signal line 42 and the second conductive pad 48 is connected to the second signal line 44. The conductive pads 46, 48 are formed by coating the ITO layer on the first substrate 4, the two The conductive pads are separated from each other, and the pair of pads comprise a touch chamber 5, as shown in FIG. As shown in Fig. 3, the insulating layers 35, 37 are formed of insulating layers 098137414 Form No. A0101 Page 11 / Total 32 pages 0993044619-0 201027404 Electrical layers 46, 48 and signal lines 42, 44 metal layers. A conductive pad may be applied to cover all areas of the touch chamber 50, but is preferably applied only to a portion of the touch chamber 50. For example, the size of the contact end of the stylus is about 〇. 7 mm, and if the width of the touch chamber is smaller than the size of the contact end of the stylus, the touch of the human finger or the pen can be detected even if the conductive pad covers the portion of the touch room 50. Area. And if the conductive pad overlaps the first signal line 42 and the second signal line 44, if the transparent conductive layer 62 is divided as described below, the conductive pad area can be minimized and the transmittance of the touch panel can be increased. Preferably, the coated area of the conductive pad should be minimized to achieve cost reduction and high transmittance of the touch panel. According to the structure described above, if the human body member contacts the second substrate 6 , the second substrate 60 is bent. And contacting the first image, if the contact with the dotted line is generated in the second substrate and the second conductive pad 48 is electrically connected to each other by the transparent conductive layer 62 of the lower surface of the second substrate 6. Therefore, the position signal generated by the transmission medium 1C 71 and applied to the first signal line 42 can be transmitted to the second signal line 44 via the phase connection _ turtle connection conductive pad, and the drive 1C 72 is also received. Thus, the coordinates of the touch point can be obtained. As shown in FIGS. 3 and 4, the circuit pattern of the signal line on the first substrate 40 and the insulation of the metal layer of the signal line are almost the same as those of the TFT of the LCD or AMOLED. The pattern and insulation are the same. Therefore, in order to manufacture the touch panel of the present invention, it is possible to use a proven TFT manufacturing method to achieve reliable mass production with stable quality and low cost. Preferably, the touch panel 50 can be designed to have the same resolution as the pixels of the display panel 2'. For example, if the touch panel of the present invention is applied to a 12"LCD panel, the touch chamber 50 can be clarified with the LCD pixels. The same degree 丨 366 * 768 or 098137414 Form No. A0101 Page 12 / Total 32 pages 〇 993 201027404 1920 * 1080 solution lizard. The 1366*768 resolution table provides 1366 touch chambers and 768 touch chambers vertically. However, the touch chamber can have a reduced resolution in an integer ratio to the resolution of the display panel. If the touch chamber resolution is the same as the resolution of the display panel or the integer ratio is reduced, the line pattern of the first signal line 42 and the first signal line 44 of the touch panel can be connected to the gate line and the solid line of the display panel. The alignment of the circuit pattern increases the transmittance of the touch panel 20 and the quality of the display panel, and prevents the Murray effect of the waveform from being displayed due to interference between the signal lines. ❿ Figure 5 shows another method of preventing the Murray effect, in which the diffusion sheet 9 is additionally provided between the display panel 20 and the touch panel, which prevents the Murray phenomenon although the touch panel of the touch panel The line pattern is aligned. The fourth line shows only the example touch with $兴度

And including the transfer of the ic 71, the 'signal processor 73, the time controller 7.2 and the memory T& f ϋ 谓 8 8 〇 〇 位置 位置 位置 位置 位置 位置 位置 位置 位置 位置 位置 位置 位置 位置 位置 位置 位置 位置 位置 位置 位置 位置 位置 位置 位置 位置 位置 位置 位置 位置 位置 位置 位置 位置 位置 位置 位置 位置 位置 位置 位置 位置 位置The numbering processor 73 applies the time-division position signal to the first signal line 42 via the transmission drive 1C for a period of "T". If the touch action occurs in the right and lower touch chambers 50' position signal in the fourth figure, the signal can be in time. T3~t4 are obtained via the rightmost _th signal 44. The detected signal can be transferred to the touchmeter detector 8〇, which will generate a coordinate value corresponding to the touch position. 098137414 0993044619-0 Form No. A0101 Page 13 of 32 201027404 However, during data processing, the touch position detector 80 can be "busy" and unable to capture position signals, then the lost signal cannot be recovered and the reliability of the touch panel is reduced. To avoid this, the position signal transceiver 70 has a memory 75, and the memory 75 has an absolute address corresponding to the coordinate value of the touch chamber 50 as shown in Fig. 8. In this embodiment, the memory 75 has at least 9 bits. Yuan capacity, and receiving and receiving by location signal Position of the received signal 70 may coordinate values " D3, S3 "is stored in the position " m9 ". The stored signal data can be called and used by the touch position detector 80. For example, each touch position detector 80 scans for a transmitted signal that reads the memory to determine if the missing signal is present. If the resolution of the touch chamber 50 is 1366*768, the capacity of the memory 75 needs at least 1049088 bits, so there should be about 132 K bits. Figures 9 to 11 show a transparent conductive layer 62, which is coated. The cloth is formed on the lower surface of the second substrate 60. As shown in FIG. 3, a transparent conductive layer 62 may be formed to cover the entire second substrate 40. In this case, the formation method of the transparent conductive layer 62 may be simple, but the transmittance may be lowered. In order to avoid a decrease in the transmittance, the transparent conductive layer may be divided into regions corresponding to the touch chamber 50, as shown in Figs. 10 and 11. Fig. 10 shows a specific embodiment in which a transparent conductive layer 62 is formed in a laterally divided touch chamber group. 11 shows a specific embodiment in which transparent conductive layers 62 are formed in each of the touch chambers 50, respectively. If the area of the transparent conductive layer 62 is minimized as long as it can contact the conductive pads 46, 48, it can increase the light transmittance of the touch panel and the quality of the display panel. At the same time, the more the transparent conductive layer 62 is divided, the manufacturing method of the second substrate 60 is more complicated, and thus, the optimal touch panel method can be selected according to the use and requirements of the display panel. 12 to 14 show various spacer examples, preferably, as described above, 098137414, Form No. A0101, Page 14 / Total 32, 201027404. The first substrate 40 is made of glass because by using the display panel 2 The conventional manufacturing method forms a signal line pattern and a connection guide, and the signal line is simple. If all of the signal lines are formed and the ICs are mounted on the first substrate 4A, the second substrate 6A can be mounted with a driver, so that the second substrate 60 is manufactured by 臈. If the first soil portion is made of a film, it is elastic, more spherical spacers 25 to 2, a substrate 40 and a second film 60, and to maintain a gap. The enemy is placed in the first plurality of pattern spacers 25b. If a film is used for the second j/collar outer panel 60, the elasticity of the crucible is high, and the first substrate 40 and the second substrate are in safe contact with each other. However, when the film substrate is weak against the pen or other sharp objects, it will cause a decrease in the _, and if the second substrate is made of glass,

098137414 is less, but the elasticity of the glass scale substrate is affected by the situation, and it is difficult for the case to be low and to obtain stable touch sensitivity. If the substrate is made thin and smart, it is difficult to manufacture the method and the manufacturing method is unsatisfactory. :...nitelsecfucil machine selection nights 12th to 14th shows another use of the second substrate, which has a suitable thickness ^^ for a stable contact between the fortune 40 and the second and second. Referring to FIG. 12, a plurality of conductive barriers 6^ are patterned on the lower surface of the second substrate 60, and the conductive layer 64 is coated with the surface of the C-based spacer 25c and the conductive layer 64 is connected to the transparent conductive layer. Preferably, the conductive layer 25c has one end fixed to the lower surface 2 of the second substrate 60. It is spaced from the conductive pad at the other end. At least one of the conductive spacers 25 is over the conductive pads 46 and the second conductive pads 48. In addition to the structure described above, if the second substrate 60 is bent downward by the hand phase 22, the two substrates 60, and the conductive spacers 25c will be interesting. [Form No. A0101 Page 15 / Total 32 pages 201027404, 48, then The electrical connection is achieved between the first conductive pad 46 and the second conductive pad 48 via the conductive layer 64 of the conductive spacer 25c, that is, the small curvature of the second substrate is sufficient to achieve a sufficient electrical connection between the conductive pads. Fig. 14 shows another embodiment of the present invention in which the first conductive pad 46 and the second conductive pad 48 alternately have a recess 52 and a projection 54, and the recess 52 and the projection 54 are engaged and spaced from each other. According to this configuration, the conductive pads can be in close contact with each other although the spacers are placed at any position.

According to the invention as described above, the signal line is formed longitudinally and laterally on the first substrate 40, and the touch chamber 5A includes a pair of conductive pads 46, 48, and a transparent conductive layer 62. The second substrate 6 is the present invention. An important feature is that the touch panel can be manufactured by using a display panel such as LC, which is manufactured by the company, to achieve mass production, cost reduction, and reliability. Another feature of the present invention is that the line 4 pattern of the touch surface slope number ^ line can be displayed

The circuit pattern of the signal line of the display panel 20 is aligned, so that the manufacturing method of the TFT substrate can be almost used, and the waveform generated by the interference between the display device signal and the touch panel signal can be prevented; the Murray: the response* and the placement For display

The panel between the panel 2 and the touch panel is a j-system: 0_ life prevents the Murray effect. And, if the second substrate 6 is made of glass, the electrical spacer 25c can compensate for the poor flexibility of the relatively thick glass substrate, so that it is not necessary to grind the green glass to a complicated method of 2 to 0.3 mm. And problems such as weak glass and easy scratching can be avoided. However, the present invention is not limited to various modifications and the intention of the present invention. The present invention has been described with reference to the preferred embodiments, the above specific embodiments, and those skilled in the art, without departing from the scope of the application of the invention.

Since the touch system is detected by digital signals, the response speed is high and noise and environment are prevented. The impact of dysfunctionality and mass production and low cost is achievable.
