Driving backplane, display panel and method for manufacturing the same

Abstract

A driving backplane includes a base, and a pixel driving circuit, a first electrode and a first piezoelectric block that are disposed in the sub-pixel region. The pixel driving circuit is disposed on the base. The first electrode is disposed at a side of the pixel driving circuit away from the base. The first electrode includes a first sub-electrode pattern and a second sub-electrode pattern that are in a same layer and are spaced apart to be insulated from each other, and the first sub-electrode pattern is electrically connected to the pixel driving circuit. The first piezoelectric block is disposed between the pixel driving circuit and the first electrode, and the first sub-electrode pattern and the second sub-electrode pattern are in contact with the first piezoelectric block.
