Problems solved by technology

Therefore, the disadvantage of the existing InCell type touch display panel structure is that: when applied to a touch display panel with high touch precision (that is, smaller pads) and a larger size, the touch drive electrodes 10 If the number is large, the number of corresponding touch driving signal traces 301 will also be large, which will occupy a wider panel frame area, which is not conducive to the design of a narrow frame

Abstract

The invention provides a narrow-bordered In Cell-type touch display panel structure. By setting m control signal lines (TL(1) to TL(N / m)) and N / m touch drive signal lines (CL(1) to CL(m)), and by respectively setting m TFT (T1 to Tm) corresponding to each touch drive signal line, touch drive signals can be provided for N touch drive electrodes (1); compared with the prior art, N touch drive signal lines with the same number as the N touch drive electrodes are set, so that the number of the signal lines in border areas on the two sides of the panel can be reduced, the widths of the border areas can be reduced, and thus a narrow-bordered design can be conveniently achieved.

Description

technical field [0001] The present invention relates to the field of display technology, in particular to a narrow frame InCell type touch display panel structure. Background technique [0002] Liquid Crystal Display (LCD) has many advantages such as thin body, power saving, and no radiation, and has been widely used, such as: mobile phone, personal digital assistant (PDA), digital camera, computer screen or notebook computer screen, etc. [0003] With the development and progress of liquid crystal display technology, people have put forward higher requirements for the display quality, appearance design, and human-machine interface of liquid crystal displays. hotspot. [0004] Touch technology has developed rapidly in recent years, and a variety of touch technologies have been put into mass production. For the existing touch display panel, according to the different setting positions of the touch sensor (TouchSensor), it can be divided into the type where the touch sensor ...
