Description

technical field [0001] The invention relates to the field of liquid crystal display, in particular to a thin film transistor array substrate and a liquid crystal display panel. Background technique [0002] A liquid crystal display panel (Liquid Crystal Display, LCD) is a common electronic device, and is favored by users because of its low power consumption, small size, and light weight. The integration of touch display is also known as a hotspot along the display panel research, and low temperature polysilicon (LowTemperaturePoly-silicon, LTPS) incell technology is regarded as a high-end technology in this field. The so-called incell technology refers to embedding the touch panel function into the liquid crystal pixel (Pixel). In the traditional pixel design process, there is a relatively large overlapping area between the sensing traces, gate lines, and data lines of the sensing electrodes and the common electrode layer. Therefore, the sensing electrodes of the sensing el...

AI Technical Summary

Problems solved by technology

At the same time, since there is resistance among the sensing lines, gate lines, data lines and the common electrode layer of the sensing electrodes, the resistance-capacitance (RC) load of the pixel is relatively large, thereby affecting the display of the entire liquid crystal display panel. Effect

To sum up, in the prior art, the RC load of the pixel is relatively large, and the display effect of the entire liquid crystal display panel is not good.
