Abstract
Official abstract text for this publication.
A touch screen and a manufacturing method thereof, and a color filter substrate and a manufacturing method thereof are provided in the invention. The touch screen comprises a substrate, a plurality of touch regions defined by a plurality of first signal lines and a plurality of second signal lines are provided on the substrate. In each touch region, the first signal line is connected with a first piezoelectric switch, the second signal line is connected with a second piezoelectric switch, when the touch region is touched by a force the first piezoelectric switch and the second piezoelectric switch are turned on and transfer voltage signals respectively via the first signal line and the second signal line to determine the coordinate of the touched touch region.
