Embodiment Construction

[0039] see figure 1 , which shows a schematic diagram of an equivalent circuit of a flat panel display with a touch function proposed by an embodiment of the present invention. In this embodiment, the flat panel display 100 is, for example, a liquid crystal display, including a substrate 110 , another substrate (not shown) corresponding to the substrate, and a liquid crystal layer (not shown) between the two substrates. The flat panel display 100 includes a plurality of gate lines, such as G(n-1), G(n) and G(n+1), and a plurality of data lines, such as D(n-1), D(n) and D(n+1). These gate lines and these data lines are intersected to divide the flat panel display 100 into a plurality of pixel areas, for example, gate lines G(n-1), G(n) and G(n+1) and data lines D( n−1), D(n), and D(n+1) intersect each other to form four pixel regions. The flat panel display 100 is respectively provided with a pixel transistor 111 and a pixel electrode 112 in each pixel area, wherein the pixe...

Abstract

The invention discloses a substrate with touch control function, a touch control device is arranged on the substrate and comprises a power line, a photodetector and a read line, wherein the photodetector is electrically coupled to the power line and two specifically gate lines in gate lines, and produces different output signals according to different illumination extents; the read line is electrically coupled to the photodetector to output the output signals; the photodetector comprises a read switch and a photosensitive switch, wherein the read switch is electrically coupled to one of the two specifically gate lines so as to determine whether switch-on according to signals transmitted, the photosensitive switch is electrically coupled to the other one of the two specifically gate lines and the power line, and produces different leakage current according to different illumination extents, and the signals on the other one of the two specifically gate lines and the power line are coordinated to control whether the photosensitive switch is operated under close state. The invention also discloses a liquid crystal display with touch control function and an operation method for drivingthe substrate with touch control function.

Description

technical field [0001] The invention relates to the field of touch detection, and in particular to a substrate with touch function, a display with touch function and an operation method for driving the substrate with touch function. Background technique [0002] With the development of technology, flat-panel displays (such as liquid crystal displays) are widely used in mobile phones, notebook computers, and desktop display devices due to their advantages of high image quality, small size, light weight, and wide application range. Various consumer electronic products such as TVs and TVs have gradually replaced traditional cathode ray tube display devices and become the mainstream of display devices. [0003] The touch device provides a new human-computer interaction interface, which is more intuitive and more humane in use. It is a trend in the development of the flat-panel display to integrate the touch-control device with the flat-panel display so that the flat-panel displ...
