Embodiment Construction

[0031] Please refer to image 3 , image 3 It is a schematic diagram of the touch display device 200 of the present invention. Such as image 3 As shown, the touch display device 200 of the present invention includes a controller 210 , a display panel module 220 , and a touch panel module 230 . The touch panel module 230 is used to receive a user's touch input to generate a touch signal. After the control chip 232 of the touch panel module 230 reads the touch signal, the control chip 232 of the touch panel module 230 converts the touch signal into a position signal, and transmits the position signal to the controller 210 . The controller 210 is used to generate corresponding instructions according to the position signal, control the operation of the touch display device 200 according to the instructions, and transmit the operation screen data of the touch display device 200 to the display panel module 220 . The display panel module 220 is used to display the operation scre...

Abstract

The invention discloses a touch control signal reading method for a touch control display device. The method comprises the steps that the touch control display device is provided, wherein the touch control display device comprises a display panel module and a touch control panel module; a plurality of scanning lines for sequentially starting the display panel module are provided; within a certain preset time span after each scanning line is started, the electric potential of a plurality of data lines of the display panel module is controlled to be ground potential, and the touch control panel module is controlled to read touch control signals. According to the touch control signal reading method for the touch control display device, the touch control panel module is prevented from being interfered by signals of the display panel module when reading the touch control signals.

Description

technical field [0001] The present invention relates to a touch signal reading method of a touch display device, in particular to a touch signal reading method of a touch display device which can avoid signal interference. Background technique [0002] Please also refer to figure 1 and figure 2 . figure 1 It is a schematic diagram of a display panel module in the prior art. figure 2 for figure 1 A schematic diagram showing the relevant signals of the panel module. As shown in the figure, the display panel module 100 includes a plurality of pixels P, a plurality of scan lines G1-Gn, and a plurality of data lines S1-Sn. The display panel module 100 turns on each scan line G1-Gn sequentially from top to bottom. The scan lines are used to electrically connect the pixels P coupled to the scan lines to the data lines S1-Sn when turned on, so as to write display data on the pixels P coupled to the scan lines via the data lines S1-Sn. Pixel P. The common voltage signal Vco...
