Abstract

The embodiment of the invention discloses a touch display panel and a touch display module. The touch display panel comprises a substrate, a plurality of first electrodes and a plurality of second electrodes both arranged on the substrate, the plurality of first electrodes are alternated to form a plurality of first grids; the second electrodes and the first electrodes are arranged on the same layer in a crossed mode, the second electrodes are disconnected at the crossed positions of the second electrodes and the first electrodes, the touch display panel also comprises a plurality of conducting layers arranged in first grids and at least covering a part of the second electrodes located in the first grids, and at least part of the conductive layers in the adjacent first grids are connected.The touch display panel also comprises an insulating layer at least covering projection areas of connection areas of the adjacent conductive layers on the first electrodes. Compared with the priorart adopting conductive connection wires or conductive connection grids, the touch display panel is higher in induction precision, and the reliability of the touch display panel is improved.

Description

technical field [0001] The present invention relates to the technical field of touch control, in particular to a touch display panel and a touch display module. Background technique [0002] At present, touch technology has been widely applied to various electronic devices, such as mobile phones, computers, and vehicle display screens. According to different sensing principles, touch screens are divided into: resistive, capacitive, optical, acoustic, and electromagnetic. Because the capacitive touch screen has the advantages of fast response speed, high sensitivity, good reliability and high durability, the capacitive touch screen is more widely used in various products. [0003] Traditional capacitive touch screens mostly use indium tin oxide as electrodes. Although indium tin oxide has high light transmittance, indium tin oxide has relatively high resistance. If indium tin oxide is used to manufacture the electrode type of a large-scale capacitive touch screen, the high ...
