Description of the Invention: [Technical Field] The present invention relates to a display device and a driving method thereof for a display panel, and in particular to a sensor having a relatively uniform sensitivity A display device and a driving method thereof. [Prior Art] In various input panel products, the input panel of the external sensing film generally reduces the penetration by about 20% in addition to the additional cost. The diffused input panel utilizes the characteristics of Amorphous-Si to design a sensing circuit capable of sensing touch and integrate the sensing circuit into the thin film transistor array process of the liquid crystal display. In contrast, embedded input panels have low cost and better optical characteristics, and thus gradually replace the input panel with an additional sensing film. Figure 1A is a circuit diagram of a conventional display device with an embedded input panel. The conventional display device includes a rear display panel 110, a gate driver 120, and a signal processing circuit 13A, and the embedded display panel no includes the drain wires GLu GL GLin and the signal reading line RL. ~ RL1M's plurality of sensing circuits, such as sensing circuits 111 to 113, and each sensing circuit is coupled to a gate line and a signal reading line. 〃 Figure 1B shows the driving of the conventional display device 1〇〇 Waveform timing diagram, where VR is the inductive signal on the sense signal read line, and sg is the gate signal generated by the gate driver 120. Please also refer to Fig. = 5 26418twf.doc/n 200941433 iTwU / I yj and Figure IB The gate driver 120 sequentially outputs the gate pulses PUn~PU1N in a meander period. The sensing circuit in the embedded display panel no is sequentially activated according to the gate pulses PUu~PU1N to sense the desired The touch point of the display panel 110 generates a corresponding sensing signal. For example, when the embedded display panel 110 is normally pressed, the sensing signal VR will exhibit waveforms as indicated by reference numerals 141 and 142. Signal processing The circuit 130 will determine whether the touch control point of the embedded display panel has been touched according to the sensing signal. It is worth noting that the embedded display panel 110 may not be received for a short time between two adjacent face periods. For any gate pulse, this short time is the blanking time TB. During the blank period TB, 'because the gate signals SGU~SG1N are low, the level of the sensing signal VR will drop' and the next one will be At the beginning of the face, it is gradually pulled up to the normal level. However, if the embedded display panel 11 is pressed again during the period when the inductive signal VR is pulled up to the normal level, the inductive signal VR will appear as the reference numeral 143 and The waveform shown in 144. At this time, the signal processing circuit 130 cannot correctly determine the level of the sensing signal VR, thereby reducing the recognition degree of the uppermost portion of the enter-in display panel 110. To solve the above problem, FIG. 1C and FIG. 1D is a timing diagram showing another driving waveform of the conventional display skirt 100. In FIG. 1C, the driving method is to divide the gate pulse PU1N across the gap between two adjacent pupil periods. During the period τΒ, the 'sensing signal VR will remain at the normal level during the blank period Tb. However, this driving method can improve the sensitivity of the input panel, but with the width of the gate pulse Ρϋ1Ν Change 26184twf.doc/n 200941433 Λ &V f V/ > Large, the circuit architecture of the device 100 will be more complicated. On the other hand, in Figure 1C, this driving method is in the embedded display panel 110. A gate line is configured to transmit the gate signal SGi(n+i). Therefore, the embedded display panel Π0 will receive the gate during the blank period TB.

Since the width of each gate pulse is the same, and the present invention does not need to configure an additional gate line, the present invention can effectively reduce the circuit complexity of the display device and the area of the cloth φ. To make the above features of the present invention The advantages and advantages of the display device are described in detail below with reference to the accompanying drawings. FIG. 2 is a circuit diagram of a display device according to an embodiment of the invention. Referring to FIG. 2, the display device 200 includes a display panel 210, a gate driver 220, a signal processing circuit 230, and a source driver 240. In addition, the display panel 210 includes N gate lines GL^GLn and multiple numbers. The sensing circuit and the plurality of signal reading lines RL are widely RLM, wherein the sensing circuits are, for example, the sensing circuits 211 to 213 in FIG. 2, and N is a positive integer. 2, the signal reading line RLh-RLm is alternately arranged with the gate line GLpGLn. The sensing circuit in the display panel 210 is disposed at the intersection of the gate lines GL!~GLN and the signal reading lines RLi~RLM, and Electrically connected to the corresponding gate line and the signal reading line. For example, the sensing circuit 211 is disposed at the intersection of the gate line GLi and the signal reading line RLM, 200941433 η.υ/υ/υ 26418twf.doc /n is electrically connected to its corresponding gate line GLi and signal reading line RLM. Further, the gate driver 220 is coupled to the gate line GLpGLn. The signal processing circuit 230 is coupled to the signal reading line RLHRLm. The source driver 240 is coupled to the display panel 210. It is worth mentioning that the configuration of the sensing circuit can be arranged according to the arrangement of the pixels (not shown) in the display panel 210. Therefore, in this embodiment, each element can be combined with an inductive circuit. However, those skilled in the art can also adjust the correspondence between the pixel and the sensing circuit according to the resolution of the display panel. In addition, in the embodiment, the display panel 21 is a desired input panel, and the sensing circuit can be implemented by using a charge sensing circuit or a current sensing circuit. 3 is a timing diagram of driving waveforms of a display device according to an embodiment of the invention, wherein VR3 is an inductive signal on an inductive signal reading line, and SG wide SGN is a gate signal generated by the gate driver 220. Referring to FIG. 2 and FIG. 3 simultaneously, the gate driver 220 sequentially turns off the gate pulse PUHPUn in one frame period and transmits it to the display panel 210 through the gate lines GLi to GLn. Here, the 'gate line (3⁄4 is used to transmit the gate pulse pUi, the gate line GL2 is used to transmit the gate pulse PR' and so on, and the ith closed line GLi is used to transmit the ith gate pulse , 丨 is a positive integer and i笈· SN. On the other hand, the source driver 240 transmits a data signal to the display panel 210 according to the timing control of the gate driver 22〇. Thus, the pixels in the display panel 210 will be In addition, the sensing circuit in the display panel 210 is also activated according to the gate pulse pUn~pu 26418twf.doc/n 200941433 d. 1.W / V/ / v. A plurality of sensing signals are generated by sensing the touch points of the display panel 210. Thereafter, the signal processing circuit 230 determines whether the touch points of the display panel 210 have been touched according to the sensing signals. The pole driver 220 sequentially generates the gate pulse pu wide PUn at a specific interval time Ti in one picture period, and is separated by a gate interval pun pun with a gate interval pun pun, and then generates a next 昼 plane period. The gate pulse rol~PUN. Among them, between the screens The ratio of the time Tj to the specific interval time Ti is between 0.7 and 1.3, and the width w of the gate pulse PI^-PUn is the same and can be between 6.7 microseconds and 71.4 microseconds. When the sensor 210 has not been touched in a kneading period, the sensing signal VR3 will be maintained at a certain level. Relatively when the display panel 21 is touched in a picture period, the sensing signal VR3 will be presented as a label. Waveforms shown in 341 and 342. In addition, since the ratio of the screen interval time to the specific interval time may be between 〇.7 and 13, when the display panel 210 has not been touched between two adjacent ®面® periods The inductive signal VR3 can still be maintained at a certain level. In contrast, when the display panel 210 is touched at the beginning of each kneading period, the inductive signal VR3 exhibits waveforms as indicated by reference numerals 343 and 344. Therefore, it can be seen that since the sensing signal VR3 is maintained at a relatively stable specific level, the identification accuracy of the first few gate lines is not affected. Thus, the uppermost portion of the display panel 210. Inductive sensitivity will not drop The sensitivity of the panel as a whole is more uniform, and the additional gate line is not required, and the width W of each gate pulse is also the same, so the display can be effectively reduced.

Therefore, when the display panel has not been touched, the sensing signal transmitted by the signal reading line will be maintained at a certain level. In contrast, the sensing sensitivity of the uppermost portion of the display panel does not decrease, thereby increasing the sensing sensitivity of the display panel. In addition, since the width of each gate pulse is the same, and the present invention does not require an additional gate line, the present invention can effectively reduce the circuit complexity and layout area of the display device. Although the present invention has been disclosed in the above preferred embodiments, it is not intended to limit the invention, and any one of ordinary skill in the art can make some modifications and refinements without departing from the spirit and scope of the invention. Therefore, the scope of the invention is defined by the scope of the appended claims.
