Problems solved by technology
That is, the touch function and the display function need to set up corresponding circuits separately, which means that the thickness of the LCD screen needs to be increased
Secondly, in the process of using in-cell technology to manufacture liquid crystal displays, it is relatively complicated to form a semiconductor manufacturing process that requires separate circuits for the touch function and display function, which will affect the product yield; in addition, setting the drive circuit for the touch circuit It will also lead to a decrease in the light transmittance of the LCD screen, which will lead to a deterioration in the quality of the display screen in severe cases.

The invention relates to an array substrate, a display device and a touch sensing method. The array substrate comprises an underlayer. Multiple rows of scanning lines, multiple columns of first data lines and multiple pixel circuits are arranged on the underlayer. Each pixel circuit is connected with one row of scanning lines and one column of first data lines. Multiple columns of second data lines are further arranged on the underlayer. Multiple touch sensing parts for generating touch sensing signals are arranged in overlapped regions of the columns of second data lines and at least two rows of scanning lines. Working circuits of the array substrate can be reduced, and the product narrow-border tendency can be achieved. The production process can be simplified, and the yield of products can be increased.
Description
technical field [0001] The invention relates to the field of liquid crystal display, in particular to an array substrate, a display device and a touch sensing method. Background technique [0002] In the prior art, the in-cell technology is used to embed the touch panel on the liquid crystal panel, and the positioning function is integrated on the array substrate, so as to realize thinning and lightening of the liquid crystal display. First of all, the touch panel needs to be provided with driving lines and sensing lines, and the liquid crystal panel needs to be provided with scanning lines and data lines. That is, the touch function and the display function need to set corresponding circuits separately, which means that the thickness of the liquid crystal display screen needs to be increased. Secondly, in the process of using in-cell technology to manufacture liquid crystal displays, it is relatively complicated to form a semiconductor manufacturing process that requires s...
