Abstract
A display apparatus and a method for transmitting control signals are disclosed. The display apparatus comprises comparatively a fewer number of control signal lines between the timing controller and the gate driver and/or between the timing controller and the source driver to transmit control signals. Thus, problems due to system complexity, noise and electromagnetic interference may be reduced, and the overall fabrication cost may be effectively reduced.
Claims27
A display apparatus, comprising:
- a timing controller, for outputting an image data, a clock signal, a mode signal and at least one command signal according to a timing sequence, wherein the timing controller encodes a plurality of control signals and adds in the command signal according to the timing of the clock signal and the mode signal;
- a driver unit, coupled to the timing controller, for receiving the image data and decoding the command signal to recover the control signals according to the timing of the clock signal and the mode signal;
- and
- a display panel, coupled to the driver unit, for displaying pictures when driven by the driver.
A method for transmitting control signals, comprising:
- providing a plurality of control signals;
- encoding and adding the control signals in at least one command signal, wherein a command mode period is defined using a mode signal, a plurality of command code periods is defined in the command mode period by referring to a timing of a clock signal, wherein each of the command code periods represents one of the control signals, and a logic value of the command signal in the command code periods is determined according to a state of the corresponding control signal;
- transmitting the clock signal, the mode signal and the command signal to a next stage circuit;
- and
- decoding the command signal through the next stage circuit according to the timing of the clock signal and the mode signal to recover the control signals.
