Abstract
Provided are a driver chip, a display screen and a display device. The driver chip is configured to drive a silicon-based display screen, and the driver chip is composed of a bridge chip and a screen driver chip. A signal interface circuit of a first signal processing circuit in the bridge chip receives video signals of each frame of picture. A drive controller controls video signals of P pixels among the video signals of one frame of picture to be output at a first preset transmission speed to a second signal processing circuit of the screen driver chip each time. A signal processor of the second signal processing circuit in the screen driver chip converts the video signals of all of the P pixels into data drive signals and outputs at a second preset transmission speed data drive signals of Q pixels in one frame of picture to a data processing circuit each time. The data processing circuit is configured to convert the data drive signals into display driving signals, sequentially output the display driving signals to pixels in each row, and control each pixel.
