Description

technical field

[0001] The invention relates to a touch panel structure and a touch display device, in particular to a touch electrode designed as a triangle, which can effectively reduce the routing area, increase the sensing sensitivity, increase the resolution of the touch panel, and reduce the load on the driving integrated circuit. 1. A capacitive touch panel structure and a touch display device capable of enlarging the operating area. Background technique

[0002] see figure 1 A structural schematic diagram of an existing capacitive touch panel is shown. In the capacitive touch panel 10, a plurality of X-axis electrodes 11 and a plurality of Y-axis electrodes 12 are alternately arranged on the same surface of a substrate 15, and the plurality of X-axis electrodes 11 are arranged in multiple rows horizontally, and multiple Y-axis electrodes 12 are arranged in multiple columns vertically, and the shapes of X-axis electrodes 11 and Y-axis electrodes 12 are arranged in a ...
