Problems solved by technology

However, in the process of integrating the touch function into the display, due to the design of the sensor and the lead-out, additional materials are required to realize it, which will increase the production process of the display equipped with In-Cell touch, thus making the display equipped with In-Cell touch The cost of an In-Cell touch display is higher than that of a general display, and it also leads to the problem of poor production efficiency due to the long production time

Embodiment Construction

[0014] see figure 1 , figure 1 It is a structural schematic diagram of an embodiment of the touch display panel of the present invention. Such as figure 1 As shown, the touch display panel of this embodiment includes: scan lines 11 , data lines 12 , touch leads 13 , pixel units 14 , thin film transistors (TFTs) 15 , contact holes 16 and pixel unit groups 17 .

[0015] One data line 12 is electrically connected to a column of pixel units 14 through TFTs 15 , and the number of scan lines 11 is the same as the number of rows of pixel units 14 , and is also electrically connected through TFTs 15 .

[0016] Wherein, the touch wires 13 and the data wires 12 are in the same layer, and the data wires 12 corresponding to the odd-numbered pixel units 14 and the data lines 12 corresponding to the even-numbered pixel units 14 are located on both sides of the touch wires 12 . Specifically, such as figure 1 As shown, the data lines 12 corresponding to the pixel units 14 in odd columns i...

Abstract

The invention discloses a touch display panel. The touch display panel comprises a plurality of pixel units arranged in an array, a plurality of data lines, a plurality of touch leads and a plurality of scanning lines, wherein any data line is electrically connected with a column of pixel units; the touch leads are located on the same layer as the data lines; the data line of an odd column of the pixel units and the data line of an even column of the data units are located on two sides of each touch lead; the distance between the data line of the odd column of the pixel units and the data line of the even column of the pixel units between the two touch leads is smaller than the distance between the data line of the odd / even column of the pixel units and the touch lead; and the row number of the scanning lines are the same as that of the pixel units. In the way, a manufacturing program can be simplified, the production efficiency can be improved, and the thickness of the touch display panel is reduced.

Description

technical field [0001] The present invention relates to the field of liquid crystal technology, in particular to a touch display panel. Background technique [0002] With the increasing development of science and technology, digital tools such as mobile phones, personal digital assistants, and notebook computers have been widely used, and the display screen is an indispensable human-machine communication interface in these tools. In order to achieve more convenient, lighter and more user-friendly purposes, many information products have changed from traditional keyboards or mice to using touch panels (Touch Panel) as their input devices. [0003] According to different touch sensing principles, touch panels can be divided into resistive, capacitive, optical, acoustic, and electromagnetic types. Among them, capacitive touch panels have fast response, high sensitivity, and reliability. It has the advantages of good quality and high durability, and has been widely used at pres...
