A touch display panel, its manufacturing method, driving method and display device

Abstract

A touch control display panel and a manufacturing method thereof, a driving method, and a display device are disclosed. The touch control display panel includes a plurality of pixel units configured on the array substrate in an array; the array substrate further includes a plurality of self capacitance touch control electrodes, which are arranged in an array, and each of which includes a plurality of electrode blocks, which have a one-to-one correspondence relationship with the plurality of pixel units; the array substrate further includes a plurality of touch control lead wires, which have a one-to-one correspondence relationship with the plurality of self capacitance touch control electrodes, the touch control lead wires are provided in gaps between adjacent columns of pixel units, which are corresponding to the plurality of self capacitance electrodes for touch control, and the plurality of self capacitance electrodes for touch control are connected with a touch control chip through the corresponding touch control lead wires.

Description

technical field [0001] The invention relates to the field of display technology, in particular to a touch display panel, a manufacturing method, a driving method and a display device. Background technique [0002] At present, with the development of display technology, display technology is widely used in TV, mobile phone and display of public information. Screen Panel) has gradually pervaded people's lives. Today, in the pursuit of excellent experience functions, touch performance has always been a major defect of large-size display panels, either limited by technology or limited by cost. [0003] At present, there are mainly three types of embedded touch panels: resistive touch panels, capacitive touch panels, and optical touch panels. The corresponding embedded touch technology has been initially applied to small-size displays. Excellent touch performance has become the direction of future touch design, and therefore, it also provides a direction for efforts to realize t...

AI Technical Summary

Problems solved by technology

And in the small size touch screen, such as figure 1 As shown, in the touch stage, the common electrodes are multiplexed as touch self-capacitance electrodes 001, and each touch self-capacitance electrode 001 is connected to the touch chip through the touch lead 002. The overlapping area between the lines and the data lines is large, resulting in a large coupling capacitance, causing interference of the touch signal to the display signal, and limiting the touch driving frequency
