TOUCH SCREEN, THE MANUFACTURING METHOD OF THE TOUCH SCREEN AND DISPLAY DEVICE

摘要

The embodiment of the present invention discloses a touch screen, its manufacturing method and a display device. The method comprise the following steps: first, forming patterns of shielding layer on a substrate; then forming patterns of bridging layer and peripheral traces on the shielding layer by a single patterning process; thereafter, forming patterns of insulating layer on the peripheral traces; and finally, forming patterns of touch control electrode layer. In the present invention, the patterning of the bridging layer and peripheral traces can be achieved by a single patterning process using a mask plate, which reduces the number of patterning processes in the manufacturing process and improves the manufacturing efficiency of the touch screen thereby reducing the cost of production.

主权项

1. A method for manufacturing a touch screen, comprising:
forming patterns of a bridging layer and peripheral traces on a substrate by a single patterning process; forming a pattern of an insulating layer on the peripheral traces; forming a pattern of a touch control electrode layer on the insulating layer, wherein the touch control electrode layer comprises touch control sensing electrodes and touch control driving electrodes which are interleaved and insulated to each other; and the bridging layer bridges the adjacent touch control driving electrodes or the adjacent touch control sensing electrodes.
