Problems solved by technology

The error caused by replacing the mask will affect the relative position of the touch electrode and the black matrix
In addition, steps such as photoresist coating, soft baking, hard baking, exposure, development, etching, and removal of photoresist are required in the photomask manufacturing process, which takes a lot of process time and reduces the production efficiency of the touch panel. , which increases the production cost of the touch panel

Embodiment Construction

[0031] The implementation of the present invention will be described in detail below in conjunction with the accompanying drawings and examples, so as to fully understand and implement the process of how to apply technical means to solve technical problems and achieve technical effects in the present invention. It should be noted that, as long as there is no conflict, each embodiment and each feature in each embodiment of the present invention can be combined with each other, and the formed technical solutions are all within the protection scope of the present invention.

[0032] In flat panel display devices such as Thin Film Transistor Liquid Crystal Display (TFT-LCD for short), the touch panel can be designed as an embedded structure, so that the touch panel can be integrated with the display panel. Such a structure can reduce the thickness of the entire display device to a certain extent and simplify the production process.

[0033] For a TFT-LCD, it generally includes a T...

Abstract

The invention disclose a touch control panel and a fabrication method thereof, which belong to the technical field of display and can be used for improving the production efficiency of the touch control panel and reducing the production cost of the control panel. The touch control panel comprises a substrate and also comprises a touch control electrode and a black matrix, wherein the touch control electrode is arranged on the substrate, and the black matrix is arranged on the touch control electrode, has same patterns with the touch control electrode, and is completely coincided with the touch control electrode. The touch control panel can be applicable for display devices with the touch control panel, such as a liquid crystal display television, a liquid crystal displayer, a mobile phone and a tablet computer.

Description

technical field [0001] The present invention relates to the field of display technology, in particular to a touch panel and a preparation method thereof. Background technique [0002] As a human-computer interaction input device, a touch panel (Touch Panel, TP for short) is widely used in mobile phones, handheld computers (Personal Digital Assistant, PDA for short), multimedia, public information inquiry systems, and the like. The user can touch the touch panel with a finger or a special stylus to recognize and select characters, symbols, menus, etc. displayed on the display panel behind the touch panel, so as to realize the input function. [0003] At present, the widely used touch panel is a capacitive touch panel. In the prior art, the capacitive touch panel generally realizes the preparation of the touch electrodes by forming a transparent conductive layer on the base substrate, and then exposing and etching the transparent conductive layer using a corresponding photoma...
