Abstract
A timing controller includes a receiver and a processor. The receiver is configured to receive image signals of image frames to be displayed. The processor is configured to determine refresh rates of the image frames to be displayed according to the image signals of the image frames to be displayed, and output different control signals according to different refresh rates of the image frames to be displayed.
Claims15
A timing controller, comprising:
- a receiver configured to receive image signals of image frames to be displayed;
- and
- a processor configured to determine refresh rates of the image frames to be displayed according to the image signals of the image frames to be displayed, and output different control signals according to different refresh rates of the image frames to be displayed,
- wherein in a process of determining the refresh rates of the image frames to be displayed according to the image signals of the image frames to be displayed, the processor is configured to:
- resolve the image signals of the image frames to be displayed to obtain data signals and timing control signals;
- and
- determine the refresh rates of the image frames to be displayed according to the timing control signals,
- wherein in a process of determining the refresh rates of the image frames to be displayed according to the timing control signals, the processor is configured to:
- determine the refresh rates of the image frames to be displayed according to time lengths each between any two adjacent active levels in a respective one of the timing control signals.
A method for driving a display device, wherein the display device includes a time controller, a reference gray scale voltage generator;
- the driving method comprises:
- receiving, by a time controller, image signals of image frames to be displayed;
- determining, by the time controller, refresh rates of the image frames to be displayed, according to the image signals of the image frames to be displayed;
- transmitting, by the time controller, different control signals to a reference gray scale voltage generator, according to the different refresh rates of the image frames to be displayed;
- and
- outputting, by the reference gray scale voltage generator, a group of reference gray scale voltages corresponding to each control signal, according to a respective one of the different control signals,
- wherein the determining the refresh rates of the image frames to be displayed according to the image signals of the image frames to be displayed includes:
- resolving the image signals of the image frames to be displayed to obtain data signals and timing control signals;
- and
- determining the refresh rates of the image frames to be displayed according to the timing control signals;
- wherein the determining the refresh rates of the image frames to be displayed according to the timing control signals includes:
- determining the refresh rates of the image frames to be displayed according to time lengths each between any two adjacent active levels in a respective one of the timing control signals.
