Abstract
A liquid crystal display and the driving method thereof. The LCD includes a timing controller, a plurality of driver chips and a display panel. The driver chips are cascaded together for driving the display panel to display frames. A driver chip includes a differential receiver, a single-ended receiver, a shift register, a differential transmitter, a single-ended transmitter and a pixel driver. The driver chip receives a pixel signal and drives the display panel according to the pixel signal, and outputs the pixel signal to the next driver chip.
Claims4
A method for transmitting data in a first driver chip and a second driver chip on a liquid crystal display (LCD), comprising:
- providing a first pixel signal, wherein the first pixel signal has one of a first signal-type and a second signal-type, and the second signal-type is different from the first signal-type;
- determining a receiving mode of the first pixel signal;
- receiving and converting the first pixel signal according to the receiving mode of the first pixel signal into a first internal signal and temporarily storing the first internal signal in the first driver chip, wherein when the first pixel signal has the first signal-type, the first internal signal converted from the first pixel signal has the second signal-type;
- and
- converting the first internal signal into a second pixel signal and providing the second pixel signal to the second driver chip according to an output mode of the second pixel signal.
