Position detection signal. Touch panels are widely used in personal devices, industrial devices, and DIDs (digitally known touch panels # are classified as resistive types, etc., but resistive touch panels are used because of simple process and low cost. Figure l A resistive touch panel is provided.

Type touch panels are widely used because of their simple process and low cost. * However, resistors The type of touch panel has some disadvantages, and the change of the second substrate 5 is unavoidable by using the second 098140545 form number A0101 page 3/48 page 〇993l 201022769 substrate 5 to detect contact. If the second substrate 5 is made of a film, the substrate may be scratched. The second substrate 5 is made of glass, and the glass substrate should be ground or etched to 0.2 to 0.3 mm to have sufficient elasticity. It will cause the structure to weaken, and it may crack before it becomes longer. And because the contact pressing of the curved substrate is rather weak, if the amount of bending is small, the contact cannot be recognized, and the contact signal is sometimes lost. Because it uses two Application of the substrates 3, 5 and the conductive layers 7, 9 of, for example, ΙΤ0

For example, in the case of an LCD panel, the single touch panel of the present invention can be assembled on a liquid crystal panel in which a TFT substrate and a color filter are combined, and then a polarizing plate is placed thereon, and the combined panel can be installed in the BLU chamber. . FIG. 3 is a schematic view showing a touch panel according to an embodiment of the present invention. A plurality of first signal lines 32 and second signal lines 34 are placed on one surface of the substrate 30. The first signal line 32 is to transmit the position detection signal, and the second signal line 34 is to receive the position detection signal. In the third figure, the signal 098140545 is shown. Form No. A0101 Page 11 / Total 48 Page 0993055115-0 201022769 Line 32, 34 They cross each other, but they can be arranged in parallel or they can be placed obliquely. The three-way switching device lion is connected between the first signal line 32 and the second signal line 34, and the gate terminal of the three-way switching device 40 is connected to the conductive pad 5 to form the touch chamber 6G. Preferably, the three-way switching device 4 (WFT. As shown, the input end of the m 4 连接 is connected to the first money line 32 and the two signal lines 34. Therefore, if the output end of the TFT 40 is connected to When the Off voltage is applied to the gate terminal, the first signal line 32 and the second signal line 34 are not connected to each other. If the voltage is applied to the intermediate terminal, the first signal line 32 and the second signal line 34 are connected to each other. Therefore, the position detection signal can be transmitted from the first signal line 32 to the second signal path 34. The conductive 塾5 is formed by, for example, selecting the top of the substrate 3. The guide can be placed. The area is covered, but 'preferably, it can be placed on a portion of the touch chamber 6, for example, the width of the finger end of the substrate 30 is about several millimeters, if the width of the touch chamber 6 is smaller than the end of the finger Width,; blue only: part of the touch room 60 'the room can still be cold hand _, preferably, guide; pad 50 is placed to align with the signal line. If the conductive 塾 50 only Covering a portion of the touch chamber 60 or placing it to align with the signal lines 32, 34, the touch panel The light rate can be greatly increased. The touch chamber 60 is formed by the active area of the split panel, where the actual contact is made, and the touch chamber 6G is arranged in a matrix format similar to the pixel array of the LcD panel. In order to have a resolution that is smaller than the display device, the integer ratio is reduced, because the size of the conductive pad 5 is preferably larger than the pixel size of the display device 20 to ensure reliable contact with the 俨098140545. However, the touch room The resolution of 60 can be the same as or larger than the form number of the display device 2A, the page number A0101, the page 12/48 page 0993055115-0 201022769. If the resolution of the touch chamber 60 and the display device 2 The resolution of the 〇 is the same or the integer ratio is reduced. The line pattern of the first signal line 32 and the second signal line 34 of the touch panel can be aligned with the line pattern of the gate line and the data line of the display device. The transmittance of the touch panel and the quality of the display device 20 are enhanced, and the Murray effect of the waveform is prevented from being disturbed by the interference between the signal lines. Fig. 4 shows another method for preventing the Murray effect. The method diffusion sheet 90 is additionally placed under the substrate 3〇, and the Murray phenomenon can be prevented even if the line pattern of the touch panel is not aligned with the line of the display panel 20.

The period of each pulse is τ. If the physical contact occurs in the right lower touch chamber of Fig. 3, the On electric waste due to the static electricity of the body is applied to the TFT 40 in the corresponding touch chamber 6, and the TFT 40 will be electrically connected. Accordingly, when the position detecting signal is applied to the first signal line 32, the position detecting signal can be obtained from the corresponding second signal line 34 of the touch chamber 6A. Referring to FIG. 6, the position preparation signal S3 is obtained through the rightmost second signal line 34 at time t3~t4, the obtained touch signal is transmitted to the signal processor 73, and the touch position detector 70 is obtained. Touch signals corresponding to coordinate values D3, S3. That is, if the pulse signal D 3 is generated and the signal S 3 is obtained, the surface sequence contact occurs, and the coordinates D3 and S3 〇. ' However, during the splicing and processing, the touch β position detector may be "Busy" and the position detection signal cannot be captured, then the lost signal cannot be recovered and the reliability of the touch panel is reduced. To avoid this, the touch position detector 70 has a memory 74' with a number of bits of the emergency room 60. As shown in Figure 7, the ®5" has an absolute address that corresponds to the coordinate value of the touch room 60. In this 趟_, the memory 74 has a capacity of at least 9 bits, and the location signal received by the touch position detector 70 can be stored at the address "η3". The stored signal data can be called and used by the signal processor 73. For example, each time the touch position detector 70 scans all of the position detection signals applied to the first signal line 32, it reads the memory 74 to check for the presence of the missing signal. If the resolution of the touch chamber 60 is 1366*768, then the capacity of the body 74 needs to be at least 1049088 bits, so about 132 kilobytes are to be scanned. 098140545 © ❹ Form No. 1010101 Page 14 of 48 0993055115-0 201022769 According to the present invention, a three-way switching device such as TFT 40 is mounted in each of the touch chambers 60, and the TFT 40 has many advantages in the LCD or The AMOLED field is an established and certified device.

This discharge can be performed during the short wait time of the next cycle read. * 098140545 Figure 10 shows a specific embodiment in which the state of the TFT 40 is changed by using the body conductivity. Because the body is electrically conductive, if the body contacts two conductive pads with different voltage levels, the conductive pads can be electrically connected. Because the form number A0101, page 17 / page 48 0993055115-0 201022769 », the impedance of the body is high, it is difficult to electrically connect the two conductive pads when the signal interval is large, but if the signal interval is about several microseconds, then The conductive pads can be electrically connected by body contact. Referring to FIG. 10, in addition to the basic structure of FIG. 3, a plurality of interrogation signal lines 36 are placed on the substrate 30, and the conductive 塾5〇 of the touch includes a first conductive connected to the gate terminal of the TFT40. The pad 5 〇 & and the second conductive pad 5 〇 b separated from the first conductive pad 50 a and connected to the gate signal line 36 . The touch position detector 7 sequentially applies the selection pulse to each of the gate signal lines 36, and the position detection signal applied to the first signal line 32 is a fixed Hi pulse 'or it may be a gate signal 〇11 of which _ ◎ is On when the On state is maintained in the On state, :..:·, ν〇 Figure 11 is a 10th figure concrete > ride ^ ^ map, display touch to 60 Formed on the substrate 3Q, the first signal line is placed longitudinally in the 3| series, and the second signal line 34 is placed laterally with the gate signal line 36. The first conductive pad 50a and the second conductive pad 50b are in the form of teeth having alternating recesses 51 and protruding turns, and the recesses are engaged with each other in such a manner as to occupy the gap. According to this structure, the second conductive pad 5〇b of the second 〇1〇1 maintains a very small gap, even if the body is connected; the two conductive pads 50a, 50b can be electrically connected by touching any part of the touch chamber 6〇. . And any other conductive object such as a pen can be electrically connected to the conductive pads 5a, 50b. As shown in Fig. 11, the gate terminal 56 of the TFT 40 is connected to the first conductive pad 50a, the source terminal 57 of the TFT 40 is connected to the first signal line 32, and the 汲 terminal 52 is connected to the second signal line 34. The signal line includes an insulated gate metal and a source metal disposed on the substrate 30, and the terminals of the TFT 40 comprise a plurality of layers of insulated gate metal, source metal, and amorphous germanium. To connect the conductive pad 50 and the TFT 40 to the signal line, a contact 5 formed by the method of IT0 098140545 Form No. A0101 Page 18/48 page 0993055115-0 201022769 is used. : Body contact with any touch room 6. 'The conductive 塾', (10) pairs will be connected to each other, and when the gate signal is applied via the gate signal line 36, the TFT4G will be electrically connected. Then, the touch position detector receives the position from the second signal line 34. If you use the L number G3 and the receiving number & 33, the touch position detector ^ can get the coordinate values D3, S3. See Figures 12 to 18 for a specific embodiment. The state of the tf paste is based on the use of electricity money generated between the conductive crucible 50 and the body according to the contact or proximity of the body relative to the conductive crucible. Referring to the fourth (4), the hand is close to the conduction at intervals d. As shown in the road map, the capacitor C can exist in the finger 2 fine material f. 'Switch to virtual ground. For example, when the body touches the guide 塾 and the stomach secret '5 table virtual ground electricity is 10 20pF, and The electrostatic capacitance is about 2~5PF when the body is in contact with the conductive layer without contact. The present invention utilizes the capacitive characteristics between the conductive 塾5〇 and the body to obtain a contact or non-contact type touch panel. Non-connected |^_ control signal, this method has many advantages. The above mentioned 4 is a sharp sense The structure of the soft contact, so the conductive pad 50 should be placed outside the substrate 3, but the conductive pad 5 should be coated with a transparent substance (such as TNO) to prevent the conductive pad 5 from being damaged, which will increase the process cost. In this embodiment, the touch chamber 60 including the conductive pad 50 may be coated with a transparent insulating layer such as a film, a plastic, an organic insulating layer, and a transmissive adhesive, or a conductive pad 5 may be placed behind the substrate 30. Any coating is applied to the touch chamber 6〇. Thereby, the high cost of the process for protecting the conductive pad 50 can be avoided, and the conductive pad 50 can be placed more stably to increase the durability of the display panel. 098140545 Form No. A0101 Page 19 / Total 48 pages 0993055115-0 201022769 Referring to FIG. 13 'In addition to the basic structure of FIG. 3, a plurality of sub-signal lines 37 are further placed on the substrate 30, and the touch chamber 60 includes the TFT 40 and the conductive pad 50.

The conductive pad 50 is connected to the gate terminal of the TFT 40. The detector 70 sequentially applies a scan pulse to the sub-signal line 37 to obtain a touch signal by electrical connection of the TFT 40. In this embodiment, the signal applied to the first signal line 32 should cause the TFT 40 to be at a high impedance. For example, driving The IC 71 outputs the necessary signal to the first signal line 32, and then maintains the first signal line 32 at a high impedance state. ❹ Figure 14 shows a specific implementation of chewing the two switching devices 42, 44 to maintain the contact position.

However, because of the line impedance of the second signal line and the parasitic capacitor, as shown in the figure, the obtained signal has a curve having a rising interval to the Hi level and a falling interval to the Low level. As shown in the 16th 圊 098140545 Form No. A0101 page 22 / 48 pages 0993055115-0 201022769, it is assumed that T1 is the gate from the first TFT 42 from the time when G1 is turned off and the monitoring time starts to the gate of the second TFT 4 4 . The pole voltage drops rapidly and the time at which the resulting signal sn falls to the full Low level, but ignores the time delay produced by the output signal Sn. If the body is close to the touch chamber 6 at the lower right of Fig. 14 at any time, a capacitor can be formed between the conductive pad 5 and the body finger 25 in the corresponding touch chamber 60. As shown in Fig. 16, if the touch is generated at the interval when G3 is Hi level, 'once the finger 25 is close to each other, the dummy capacitor is formed,

If the signal G3 When the monitoring time mode is off, &, the charged voltage in the dummy capacitor is broken, and the gate voltage of the second TF Τ 44 is slowly lowered' and the output waveform of the second TFT 44 is displayed as shown by the S3 waveform.

In this embodiment, when S3 is obtained after the gate signal G3 is turned off, the touch signal is the coordinate value 'D3, S3'. Figure 16 shows an example of getting a touch signal, but other methods are also available! Get the touch signal. For example, all of the gate signals Gn can be turned on at the same time to induce charging of the dummy capacitor between the body and the conductive pad 5?, then the sequence signal is applied to the sub-signal line 37, and the output waveform is monitored. Figure 14 is a specific embodiment in which the touch signal is obtained by a body close to the capacitor generated by the body 098140545 Form 煸珑A0101 Page 23/48 Page 0993055115-0 • 1 201022769. The assumed body finger 25 is in contact with the conductive pad bean. In this case, a capacitor of several pF is generated, and the touch signal can be obtained by ', but if the actual capacitor is connected to the conductive pad 5〇, the virtual body formed by the body approach is formed. The capacitor will perform charge sharing, so the voltage level of the gate of the second TFT 44 will be lowered, or the charging time will be lengthened, so that a more reliable touch signal can be obtained by physical contact. Figures 17 and 18 show a specific embodiment in which a more reliable touch signal can be obtained in the case of physical contact, but in the case where the body is not in contact, some embodiments can also obtain a reliable touch signal. Referring to Fig. 17, in addition to the structure of the embodiment of Fig. 14, the capacitor 54 is additionally connected between the output of the first TFT 42 and the sub-line 37. In this embodiment, the touch position detector is also scanned to each of the gate signal lines 36, or the same signal is applied to all of the gate signal lines 36. In this embodiment, the drain signal Gn and the sub-signal Auxn for monitoring are not necessarily accompanied by each other and they can be applied independently. However, if the capacitor 54 is free to discharge at the capacitor 54, it may be vaporized. The sub-signal is preferably used in the capacitor 54 by Gn | Ma §§ & © For example, the Gn On voltage is 15 volts. When Gn is applied, Dn is also applied and charged to the capacitor 54 of the gate terminal of the second TFT 44. The Dn Hi level voltage will turn on the second TFT 44, which is preferably 1 volt in consideration of Gn. Dn is supplied with a charging capacitor 54 for a sufficient period of time. The voltage at the gate terminal of the second TFT 44 is 3 volts or more higher than the voltage at the input terminal Auxn, so that the second TFT 44 is always in an on state. If the body simultaneously contacts the lower right touch chamber 60 while the sub-signal Auxn is being applied, the charge stored in the capacitor 54 is discharged and moved to the virtual 098140545 formed by the body. Form No. A0101 Page 24 of 48 0993055115 -0 201022769 Capacitor 54 until the voltage levels of the two capacitors become equal to each other. If the charging capacity of the capacitor 54 is sufficiently smaller than the charging capacity of the virtual electric grid formed by the body, the above-described charge sharing occurs, and the voltage applied to the gate terminal of the second TFT 44 may not turn on the second TFT 44 or be related to the sub-TFT. The output signal Sn of the signal Auxn can be lowered, and it can be detected and the touch signal can be obtained. The touch signals obtained in this embodiment are coordinate values D3, S3. e
