Claim Text:
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; wherein the bridging layer comprises a portion formed in a touch control area of the touch screen and a portion formed in a non-touch control area of the touch screen, and the peripheral traces are arranged on the portion of the bridging layer formed in the non-touch control area of the touch screen; forming a pattern of an insulating layer on the peripheral traces and on the portion of the bridging layer formed in the touch control area of the touch screen; forming a pattern of a touch control electrode layer on the insulating layer, wherein the touch control electrode layer comprises a portion formed in the touch control area of the touch screen and a portion formed in the non-touch control area of the touch screen, the touch control electrode layer comprises touch control sensing electrodes and touch control driving electrodes that are interleaved and insulated to each other; and the bridging layer bridges adjacent touch control driving electrodes or adjacent touch control sensing electrodes.
