Problems solved by technology

However, in a capacitive touch module using a metal grid, the connection lines in the driving electrodes and the sensing electrodes partially overlap across layers, and the parallel plate capacitance formed at the overlap will affect the sensitivity of touch detection. As a result, capacitive touch modules using metal grids are less effective in applications based on fingerprint detection

Abstract

According to the touch module and the display screen provided by the embodiment of the invention, by increasing the line width of the first grid and the second grid in the metal grid layer or increasing the number of winding turns of the first grid and the second grid, the area ratio of the first grid and the second grid can be increased; therefore, the capacitance between the first grid and the second grid is improved, the sensing detection precision of the touch module can be improved, and the touch module can achieve fingerprint recognition through the metal grid.

Description

technical field [0001] The present application relates to the field of display device manufacturing, and in particular, to a touch module and a display panel. Background technique [0002] With the continuous development of display equipment manufacturing technology, the manufacture and use of flexible screens, folding screens and other products are becoming more and more mature. These display modules usually use thinner on-screen cover and film, which reduces the capacitance penetration distance, making it possible to realize touch detection and fingerprint recognition through on-screen capacitive detection. [0003] Metal mesh technology is used in some on-screen capacitive touch modules. Metal mesh technology is to arrange metal wires with low resistance into a mesh as driving electrodes or sensing electrodes, thereby improving touch detection. At the same time, the light emitted by the display module can penetrate through the mesh of the metal grid to ensure the display...
