Problems solved by technology

Due to the structural design of the above-mentioned in-cell touch screen, it is necessary to add a new film layer (used as a transparent conductive layer for touch electrodes) on the existing TFT array substrate, resulting in the need to add a new process when manufacturing the TFT array substrate. Increase production cost, which is not conducive to improving production efficiency

Embodiment Construction

[0030] In order to make the technical problems, technical solutions and advantages to be solved by the present invention clearer, the following will describe in detail with reference to the drawings and specific embodiments.

[0031] The solution of the present invention provides a brand-new touch display panel with a built-in touch screen structure. The cathode used as a common electrode is multiplexed as a touch electrode to achieve the purpose of simplifying the structure, thereby reducing the manufacturing process of the touch display panel. and reduce manufacturing costs.

[0032] Wherein, the array substrate mentioned in the embodiment of the present invention includes: an array substrate (that is, the first substrate) and a color filter substrate (that is, the second substrate) that are oppositely arranged, such as figure 1 As shown, the array substrate specifically includes:

[0033] Substrate substrate ( figure 1 not shown);

[0034] An anode 4 formed on the base s...

Abstract

The invention provides a touch control display panel, a touch control display device and a production method and belongs to the touch control display field. The touch control display panel comprises a first base plate and a second base plate; the first substrate comprises a substrate as well as an anode, an organic light-emitting layer and a cathode formed on the substrate, wherein the cathode is composed of a plurality of first sub electrodes, wherein each first sub electrode is adopted as a touch control electrode to upload touch control scanning signals in a touch control scanning stage, and is adopted a common electrode to upload common electrode signals at a display stage; and the first base plate further comprises a driving electrode layer arranged between the anode and the substrate, wherein the driving electrode layer uploads touch control scanning signals in a touch control scanning stage. With the above technical schemes of the invention adopted, the cathode in the touch control display panel can be multiplexed as a touch control electrode in the touch control scanning stage, and at the same time, influences of the anode on the electric potential of the cathode in the touch control scanning stage can be offset.

Description

technical field [0001] The invention relates to the field of touch display, in particular to a touch display panel, a touch display device and a manufacturing method. Background technique [0002] With the rapid development of display technology, touch screen panels (Touch Screen Panels) have gradually spread in people's lives. Currently, touch panels can be classified into: Add on Mode Touch Panel, On Cell Touch Panel, and In Cell Touch Panel according to their composition and structure. Among them, the plug-in touch screen is produced separately from the touch screen and Liquid Crystal Display (LCD), and then bonded together to form a liquid crystal display with touch function. The plug-in touch screen has high production costs and low light transmittance. Low, thick modules and other shortcomings. The embedded touch screen embeds the touch electrodes of the touch screen inside the liquid crystal display, which can reduce the overall thickness of the module and greatly r...
