Abstract
The present application discloses a pixel unit and a signal processing method for a pixel unit. The pixel unit includes at least one pixel, and the pixel includes: an N-type main pixel, a P-type main pixel, and a sub-pixel; and the sub-pixel is located between the N-type main pixel and the P-type main pixel; or the pixel includes at least a first pixel and a second pixel that are adjacent to each other; the first pixel includes an N-type main pixel, and the second pixel includes a P-type main pixel; the first pixel and the second pixel share one sub-pixel; the sub-pixel is configured to generate and output a signal difference between the N-type main pixel and the P-type main pixel according to the current. By adding a sub-pixel between two main pixels, the sub-pixel generates and outputs the signal difference between the N-type main pixel and the P-type main pixel according to the current sent by the two main pixels, so that the received signal can be efficiently processed directly to reduce the amount of output data. Since there is no need to increase a circuit, the pixel area will not increase due to a complicated circuit.
