Problems solved by technology

[0005] However, the existing method has the following disadvantages: due to the high reflectivity of the metal material, there is a problem of reflection when viewing the panel, which is visible to the user and is difficult for the user to accept; moreover, the metal mesh structure is easy to Oxidation corrosion requires a protection layer or blackening treatment, which will inevitably increase production costs and reduce production efficiency

Abstract

The invention provides a capacitive touch display panel. The capacitive touch display panel comprises a thin film transistor substrate, and a liquid crystal layer, a color filter substrate, a sensing electrode layer and a polarizer which are sequentially formed on the thin film transistor substrate. The sensing electrode layer comprises transparent electrodes close to the polarizer, metal electrodes close to the color filter substrate, and an insulating layer arranged between the transparent electrodes and the metal electrodes in a clamped mode. The capacitive touch display panel comprises the sensing electrode layer, the structure that the transparent electrodes and the metal electrodes are combined is adopted for the sensing electrode layer, and therefore compared with existing double layers of metal electrodes, light reflection of the capacitive touch display panel can be effectively reduced, and the visual perception is more comfortable. In addition, the sensing electrode layer does not need to be provided with a protection layer or be darkened, and therefore procedures are saved, the production cost is reduced, and the production efficiency is improved.

Description

technical field [0001] The invention relates to the field of liquid crystal display technology, in particular to a capacitive touch display panel. Background technique [0002] Currently, touch technology has been widely applied to various electronic products with display panels, such as mobile phones, computers, personal digital assistants (PDAs), and flat-screen TVs. [0003] Touch display panels (referred to as touch display panels) can be divided into resistive, capacitive, optical, acoustic, and electromagnetic types according to different sensing principles. Due to the fast response speed of capacitive touch display panels, High sensitivity, good reliability, and high durability are recognized by the industry and are more widely used. [0004] The sensing electrodes of capacitive touch display panels usually use transparent electrode materials such as indium tin oxide (ITO), indium zinc oxide (IZO), etc. As the size of capacitive touch panel touch display panels becom...
