Problems solved by technology

[0004] In view of the shortcomings of the existing methods, this application proposes a touch module and its preparation method, a touch display screen, and a touch display device to solve the problem of effective interaction between the two metal layers of the touch module in the prior art. The capacitance Cm is easily interfered by the capacitance Cp between the metal layer and the cathode of the pixel, which affects the technical problem of the touch effect

Abstract

The embodiment of the invention provides a touch module and a preparation method thereof, a touch display screen and a touch display device. The touch module comprises a substrate layer, a first metallayer, an insulating layer, a second metal layer and a protective layer which are laminated. The second metal layer comprises a plurality of touch units arranged in an array, and each touch unit comprises a sending signal line and a receiving signal line. In the second metal layer, the positions of the transmitting signal lines and the positions of the receiving signal lines are separated and correspond to each other. The first metal layer comprises a plurality of bridging sections, the sending signal line or the receiving signal line in one touch unit extends and penetrates through the insulating layer to be electrically connected with one bridging section, and the sending signal line or the receiving signal line in the other touch unit extends and penetrates through the insulating layerto be electrically connected with the same bridging section. The first metal layer is located on the side, away from the cathode layer in the pixel layer, of the substrate layer. According to the embodiment of the invention, the interference on the effective mutual capacitance value Cm in the touch module is reduced, and the touch effect is ensured.

Description

technical field [0001] The present application relates to the technical field of touch display, and in particular, the present application relates to a touch module, a touch display screen, a touch display device and a method for preparing the touch module. Background technique [0002] At present, most touch screens adopt an On cell structure, that is, the touch module is embedded between the color filter substrate and the polarizer of the screen. [0003] The touch module generally includes an inorganic base film, a first metal layer, an insulating layer, a second metal layer, and a protective layer. The first metal layer and the second metal layer are respectively patterned Tx lines (referring to the transmission signal lines of the touch sensor) and The Rx line (referring to the receiving signal line of the touch sensor), the Tx line and the Rx line intersect to form a cross S1. Since the first metal layer is relatively close to the cathode layer of the pixel in the dis...
