Abstract: Disclosed are a capacitive touch screen and a single layer wiring electrode array. The single layer wiring electrode array includes capacitive regions and wiring regions located on one plane. Wires in the wiring regions are zigzag-shaped or wave-shaped. The capacitive touch screen includes a substrate; a single layer wiring electrode array disposed over the substrate, wherein the single layer wiring electrode array includes capacitive regions and wiring regions located on one plane and wires in the wiring region are zigzag-shaped or wave-shaped; and control ports for connecting to one or more integrated circuits, wherein the wires in the wiring regions are connected to the control ports respectively. The single layer wiring electrode array and the capacitive touch screen lower the fabrication cost and improve the display effects.

Abstract: A fingerprint information detection circuit comprises an amplification unit, a source follower unit, a reset unit, and a feedback unit. The amplification unit is coupled to the source follower unit. The reset unit is coupled to both the feedback unit and the amplification unit. The feedback unit and the amplification unit are coupled. The reset unit includes a first transistor and a reset transistor, wherein source and drain electrodes of the first transistor are coupled, wherein one of source and drain electrodes of the reset transistor is coupled to the source and drain electrodes of the first transistor.
