Problems solved by technology

However, the technology at this stage still adopts the structure of concentrating the traces in a single soldering area. The problem with this approach is that the traces must have two or more turning structures, and the turning structures will cause certain risks in the process. , such as wire breakage; in other words, the more turning structures, the lower the reliability of the product
Furthermore, the above-mentioned method will also cause part of the traces to be extended from the front to the back of the display, and then extended back to the front again to concentrate on the soldering area, and such a long trace length will lead to signal attenuation, different lengths Problems such as uneven impedance of traces

Abstract

A touch display includes a display and a touch panel. The touch panel has a flexible substrate and an electrode module arranged on the flexible substrate, wherein the electrode module has a touch electrode, a first connecting electrode electrically connected to the touch electrode and a second connecting electrode electrically connected to the touch electrode; at least one side of the flexible substrate is bent along the display surface; and the first connecting electrode and the second connecting electrode are respectively arranged on the display surface and the back surface of the display.

Description

technical field [0001] The invention relates to a touch display. Background technique [0002] In the structure of the existing touch screen, the traces of the conductive film layer used to sense the user's touch on the screen form leads from the left and right edges of the screen, and then concentrate on the welding area to connect with the flexible circuit board. Therefore, the left and right sides of the screen The wiring area on the side becomes an invalid touch area, and the wiring area is usually covered with an ink layer. The existence of the ink layer reduces the display range of the mobile phone screen. Therefore, in terms of visual experience and touch function, All have a certain impact on users. [0003] Among the technologies for solving the above-mentioned ink layer, a flexible touch-sensing conductive film layer is being developed. However, the technology at this stage still adopts the structure of concentrating the traces in a single soldering area. The pro...
