Abstract

The invention discloses a capacitive touch screen sensor. The capacitive touch screen sensor comprises a drive electrode layer and a sensing electrode layer, wherein the drive electrode layer comprises a first substrate and a first conducting film layer arranged on the first substrate; the sensing electrode layer comprises a second substrate and a second conducting film layer arranged on the second substrate; the same surface of the first substrate is provided with a compensation drive electrode and a compensation sensing electrode; any one electrode led out from the first conducting film layer is connected with one compensation drive electrode, and one compensation drive electrode and one compensation sensing electrode form a compensation capacitor, and an output end is led out from the compensation sensing electrode. The capacitive touch screen sensor and the capacitive touch screen provided by the invention compensate capacitance for a base capacitor through the compensation capacitor, so as to reduce the probability of occurrence of lineation and drifting.

Description
