Abstract: A power saving method includes enabling an input signal detection unit of the display controller for detecting a first presence of at least one input signal of the display controller, entering the display controller to a power-off mode temporarily for decreasing an operation power from a first power to a second power within a second time period when the at least one input signal is not received by the input signal detection unit within a first time period, detecting a second presence of the at least one input signal continuously by the input signal detection unit after the second time period elapses, and adjusting an operation mode of the display controller according to the second presence of the at least one input signal. The second power is smaller than the first power. The second power corresponds to a power of the display controller under the power-off mode.

Abstract: A display chip protection device for a display receiving an image signal and a power signal comprises a display chip and a protection unit. The display chip receives the power signal and the image signal from the protection unit. The protection unit is coupled to the display chip for receiving the power signal and the image signal. When receiving the power signal, the protection unit transmits the image signal to the display chip so that the display chip receives the power signal earlier than the image signal.

Abstract: An apparatus for measuring a full frame size from a digital display signal by a data enable signal and a method therefor. The apparatus includes a timing control device and a multiplexing device. The timing control device has multiple input terminals and a control signal output terminal. Each of the input terminals is capable of being coupled to a display bit of a primary color signal. The timing control device outputs a control signal through the control signal output terminal. When the timing control device is to perform display adjustment, the timing control device outputs the data enable signal to the multiplexing device and the multiplexing device applies the data enable signal to the timing control device. According to the data enable signal, the full frame size and position can be obtained.
