Abstract

The invention relates to an in-cell touch display panel including a thin film transistor array substrate, a color filter substrate, a liquid crystal molecule layer, sensing driving electrodes and touch control sensing electrodes. The liquid crystal molecule layer is disposed between the thin film transistor substrate and the color filter substrate. The sensing driving electrodes are arranged in a first direction and disposed on the thin film transistor array substrate. The touch control sensing electrodes are arranged in a second direction and disposed on a surface of the color filter substrate farther away from the thin film transistor array. The data lines of a pixel array on the thin film transistor array are used as the sensing driving electrodes to cooperate with the touch control sensing electrodes to perform a touch sensing operation.

Description

technical field [0001] The present invention relates to a touch display panel and a touch method, and in particular to an in-cell touch display panel and a touch method. Background technique [0002] In recent years, with the advancement of thinner display technology, various thinner display devices have become the first choice for consumers when purchasing monitors or TVs due to their small size, light weight, low radiation, and low power consumption. Among the display panels of various thinner display devices, the liquid crystal display panel has gradually become the most attention-grabbing thinner display panel due to the improvement of pass rate and display quality. On the other hand, since the current intuitive touch human-machine interface technology is gradually emerging in the market, the industry is investing in the development of touch display panels that integrate touch functions and display functions. [0003] Among all kinds of touch display panels, the in-cell...
