For the bistable display device, it has an inherent bistable characteristic, that is, when an image is written, it is not necessary to input an additional power source, and the image is always retained. The resistive touch panel can be combined with an electronic paper display device because of its thin thickness, small size, and low power consumption to construct a touch-sensitive electronic paper display device. The touch-sensitive electronic paper display device allows the user to directly input on the display screen, which greatly improves the user's operation convenience. However, the conventional resistive touch panel uses a type of analog converter (A/D Converter) to convert the detected differential voltage into a digital signal, and then a microprocessor directly processes the digital signal output from the analog digital converter. In order to calculate the coordinate value of the touch position; therefore, the conventional resistive touch panel can only perform the operation of the single point coordinate value at one time. When the multi-touch is used, the multi-point coordinate value cannot be correctly operated.

The first electrode 11, 11 and the second electrode line 12 are disposed to intersect each other (e.g., substantially orthogonal), and are electrically insulated from each other by an insulating layer 21 interposed therebetween. a plurality of thin film transistors 23 (only one of which is shown in FIG. 2) is disposed adjacent to the intersection of the first electrode line and the second electrode line 12 and is electrically secreted to the first electrode line second electrode line 12; Specifically, the gate g of each of the thin film transistors 23 is coupled to the adjacent first electrode line u, and the secret D is reduced to - the adjacent 5 201015396 second electrode line 12, the source S system Connected to a corresponding halogen electrode (not shown). The third electrode line 13 is located above the first electrode line 11 and the second electrode line 12 and is electrically insulated from each other by an insulating layer 2 2 located between the second electrode line 12 and the second electrode line 12; here, the second electrode line The 12 series is located between the first electrode line 11 and the third electrode line 13, and the first electrode line 11 is usually coupled to the gate driving circuit. The third electrode line 13 is disposed opposite the second electrode line 12, and a display bistable display layer 15 can be disposed above the third electrode line 13. The bistable display layer 15 can be an electronic paper display layer, which can include an electrophoretic layer and a transparent electrode layer on the side of the electrophoretic layer facing away from the third electrode line 13. It can be understood that the electrophoretic layer can also be changed to a more twisted spherical layer or a cholesteric liquid crystal layer. The extending direction of the second electrode line 13 is substantially parallel to the extending direction of the first electrode line 11, and substantially orthogonal to the extending direction of the second electrode line 12. A hollow structure 133 is formed between each of the third electrode lines 13 and the second electrode lines 12 (ie, a position where the third electrode lines I are overlapped with one of the second electrode lines 12), and an external force is applied to the second electrode lines. When 13 is above, it can flex downwardly to make electrical contact with the second electrode line I]. In this embodiment, the corresponding hollow structure of the third electrode line 13 is formed with a downwardly extending bump 131 at a position. Further, those skilled in the art can also appropriately change the structure of the third electrode wire 13 so that it can be bent downward for the purpose of applying force thereto. The embodiment of the present invention utilizes the inherent bistable characteristic of the bistable display device. When the electronic image is to be written, the second electrode line I2 is switched to the source to the source by the switch module 16 The circuit m is such that the touch bi-stable display device 1G is in the image display state to perform the _ function two times: the plurality of first electrodes, the line ii and the plurality of second electrode lines 12 are respectively used as the 6 201015396 gate line and source Line use. When the electronic switch module 丨6 turns a plurality of second electrodes, the switch is switched to the next electronic shadow to write the person, and the H1G secret touch is turned (four) to measure the state of the straight-electrode-negative injury. For the debt measurement function, at this time, the majority of the strips = electrode lines 12 (four) are used as one line, and the line 13 is used as another line.怿First-electrode biting A circuit 描述 ΨΜ β β β β β ^ ^ ^ ^ ^ ^ β β β β β β β β β β β β β β β β β , , , , , , , , , , , , , , , , , , 183, - = digital device m, - memory module 185 and an output interface 186. The 'two input/output module 181 includes a plurality of three-state gates (five) - her ate) for respectively as a signal input unit and a signal output unit, and each three-state gate has a logical "〇,,, logic "i, , and high impedance three output states. The plurality of first electrode lines 12 are connected to the two-state gate input/output module of the touch detection system 18 through the switch module 16. The plurality of third electrode lines 13 are also coupled to the touch detection. The three-state gate input/output module 181 of the system 18. The timing control module 182 is configured to generate a timing signal to control the input/output operation of the tri-state gate input/output module (8); the detection voltage source 183 is configured to pass the three-state gate input/output module ΐ8 to a plurality of second The electrode line 12 or the plurality of third electrode lines 13 provide a detection voltage in a progressive scan mode; the analog digital converter 184 is used to combine the plurality of second electrode lines π and the plurality of third electrode lines 13 The other one is converted into a digital signal by the detection telecommunication signal input through the three-state gate input/output module 181; the memory module 185 is consumed by the timing control module ι82 and the analog digital converter 184 for receiving and storing The timing signal and the digital signal are used to collect the touch position coordinates; the output interface 18 6 is used to output the timing signal and the digital signal stored in the memory module 丨85. 7 201015396 The detection process of the touch detection system 18 is roughly as follows: the timing control mode generates a timing signal to control the input rotation of the tristate gate input/output module 181, which can make the debt measurement voltage source and the 183 sweep the cat by line. Towards more; this time sequence is sent to the slave (4) module (8) to reserve storage to indicate that the second electrode line currently provided with the detection voltage is provided at each of the first electrode lines 12 During the voltage period, the third electrode and the line 13 sequentially input the debt measurement signal through the three-state gate input/output module 181 184 184, and the analog digital converter 184 converts the detected electrical signal into a recorded ship. The memory material 18 is stored to indicate the position of the third electrode line 13 currently being detected. Thereby, the single or (four) pressed multiple touch position coordinates are measured and stored in the memory phantom = 185. The value of the electrical parameter such as the current or the electric resistance is indicated by the side. Of course, it can be understood by those skilled in the art that the side power 183 can also provide a side voltage to the plurality of third electrode lines 13 in a progressive sweep mode. The plurality of second electrodes and the lines 12 are sequentially transmitted through. The three-state gate input/output mode (8) inputs the detection of the telecommunication signal to the analog-to-digital converter 184, which is far from the purpose of the invention. The timing signal and the digital signal stored in the memory module 185 can be input through the output interface 186 to one of the output interfaces 186, and the micro processing device 19 can be internally (four) generated. - Control signal to control the display of the dual-state display layer 15. > The analog-to-digital converter 184 of the embodiment of the present invention can also be changed to other digital condition generating circuits, such as the specific voltage level circuit shown in FIG.
