Abstract:
A display includes a plurality of data lines, a plurality of scan lines, a plurality of pixel circuits, a source driver, a gate driver, a timing controller and a gray scale circuit. The source driver includes a data line driving circuit for generating driving current corresponding to an image to be displayed by a pixel circuit, a current source for pre-charging the pixel circuit and a switch for electrically connecting the current source to the pixel circuit or electrically isolating the current source from the pixel circuit. The timing controller controls the source driver and the gate driver. The gray scale circuit controls the switch of the source driver based on gray scales of images to be displayed by the pixel circuits of a scan line.
