Touch Panel and Preparation Method Therefor

Abstract

A touch panel and a preparation method therefor, which relate to the technical field of electronic device preparation. The method for preparing a touch panel comprises: firstly, preparing a BM frame layer (1), and then sequentially preparing an ITO1 layer (2), an OC1 layer (3) and an ITO2 layer (4a, 4b) in the BM frame layer (1); then, preparing a window frame layer (5) outside the BM frame layer (1) by means of a printing process; and finally, preparing a designated metal wiring layer (6a, 6b) and an OC2 layer (7). The touch panel and the preparation method therefor solve the problem that a white window frame in the current industry is yellowed easily. Compared with a yellow light lithography for preparing the window frame, the printing process for preparing the window frame is simpler in production process, higher in defect-free rate and lower in corresponding cost, and can reduce pollution from discharge of wastewater and waste gas generated by the chemical solution to the environment.
