Problems solved by technology

However, in the display area (Area AA) of the touch display device, due to the interval distribution of a plurality of pixel units, the common electrode layer in the touch display device will be cut and lack part of the common voltage signal, so that the common electrode and The capacitance values ​​of the capacitors between the data lines and between the common electrode and the gate line are different, which makes the display uneven at the boundary of the pixel unit, resulting in horizontal stripes on the screen
[0006] Therefore, it is necessary to provide a touch display device to solve the problem of horizontal stripes on the screen in the above-mentioned prior art problems

Abstract

The invention discloses a touch display device. The touch display device comprises a plurality of pixel units, a driving chip and a plurality of touch wires, the touch display device further comprisesa compensation device, and the compensation device is located at the block dividing positions of the pixel units, electrically connected with the protection circuit located on the periphery of the display area and used for receiving compensation signals provided by the protection circuit so as to balance capacitance values of multiple capacitors in the touch display device. According to the invention, the problem of screen transverse lines generated when pixels on the panel of the touch display device are lightened can be effectively solved, and the delivery quality yield of products can be improved.

Description

technical field [0001] The present invention relates to the field of touch technology, in particular to a touch display device. Background technique [0002] With the increasing development of technology, digital tools such as mobile phones, personal digital assistants (PDAs), and notebook computers are all developing in the direction of convenience, multi-function and beauty. Among them, the display screen is an indispensable human-machine communication in these devices. Interface, at present, the mainstream display screen adopts liquid crystal display device. [0003] In recent years, with the rapid development and application of information technology, wireless mobile communications and information home appliances, in order to achieve more convenient, lighter and more humanized purposes, many information products have been input from traditional keyboards or mice and other devices. A touch panel (TP for short) is used as an input device, and a touch-sensitive liquid crys...
