Problems solved by technology

[0006] Existing embedded self-capacitance touch display panels usually require a set of touch circuits (including touch scanning lines, touch receiving lines, and touch self-capacitance) and a driving control part to realize the touch function. The process is difficult, and the driving cost of the panel is relatively high

Abstract

The invention provides a built-in self-capacitance touch display panel and a manufacturing method thereof. The built-in self-capacitance touch display panel comprises an array substrate, a CF substrate and a liquid crystal layer arranged between the array substrate and the CF substrate, and light enters through one side of the CF substrate and comes out through one side of the array substrate. The array substrate comprises a plurality of grid electrode scanning lines (11) arranged in the horizontal direction at intervals, a plurality of data lines (41) arranged in the vertical directions at intervals, and a plurality of pixel electrodes (50) arranged into a matrix, wherein the grid electrode scanning lines (11) also serve as touch control scanning lines, the data lines (41) also serve as touch control receiving lines, and the pixel electrodes (50) also serve as touch control self-capacitors; in this way, on the premise that the number of existing array substrate technological processes is not increased, built-in self-capacitance touch control can be achieved, and panel driving cost can be reduced. By the adoption of the manufacturing method of the built-in self-capacitance touch display panel, the number of existing array substrate technological processes is not increased, and panel driving cost is reduced.

Description

technical field [0001] The invention relates to the field of display technology, in particular to an embedded self-capacitance touch display panel and a manufacturing method thereof. Background technique [0002] With the rapid development of display technology, touch display panels have been widely accepted and used by people, for example, smart phones, tablet computers, etc. all use touch display panels. The touch display panel integrates the touch panel and the liquid crystal display panel, so that the liquid crystal display panel has the functions of displaying and sensing touch input at the same time. [0003] A liquid crystal display panel is usually composed of a color filter substrate (ColorFilter, CF), a thin film transistor array substrate (ThinFilmTransistorArraySubstrate, TFTArraySubstrate), and a liquid crystal layer (LiquidCrystalLayer) arranged between the two substrates. A driving voltage is applied to the glass substrate to control the rotation of the liqui...
