Abstract: A source driver including a data register, a level shifter, a gamma correction unit, a digital-to-analog converter and a buffer is provided. The data register stores a digital data signal. The level shifter pulls up the level of the digital data signal. The gamma correction unit provides a gamma curve. The digital-to-analog converter transforms the level-pulled-up digital data signal into an analog data signal with reference to the gamma curve. The buffer outputs the analog data signal to drive a corresponding data line. The level shifter, the gamma correction unit, the digital-to-analog converter and the buffer are all figured to receive a first set of reference voltages or a second set of reference voltages.

Abstract: A method and an apparatus for mirroring a frame are provided. The method is suitable for a display device having a first storage unit and a second storage unit. In the present method, pixel values of a pixel row of the frame are read from the first storage unit and written into the second storage unit. Then, the pixel values of the pixel row of the frame are read from the second storage unit and written back to the first storage unit. When performing one of foregoing reading and writing steps, the pixel values of the pixel row are read or written in a reverse direction to mirror the pixel row. Finally, foregoing steps are repeated to mirror each pixel row of the frame, so as to mirror the entire frame.

Abstract: An output buffer for providing an output voltage signal includes an operational amplifier, a controller and a power circuit. The operational amplifier provides the output voltage signal according to an input voltage signal. The controller judges whether a reference signal corresponding to the input voltage signal satisfies an energy-saving condition, and triggers an energy-saving operation event if yes, or triggers a normal operation event if not. The power circuit provides an energy-saving power signal to drive the operational amplifier in response to the energy-saving operation event and provides a normal power signal to drive the operational amplifier in response to the normal operation event, such that the operational amplifier provides the output voltage signal according to the input voltage signal. A voltage level of the normal power signal is higher than a voltage level of the energy-saving power signal.

Abstract: The present invention is to provide a method for converting a touch pad into a touch mode or a number-key and/or hot-key input mode, which is applicable to a touch pad including a main control unit and at least one mode conversion key. The main control unit automatically turns on the touch pad and brings the touch pad into the touch mode.

The plural sets of absolute coordinates correspond respectively to a plurality of arrayed number and/or function blocks each having a unique key code value, thus allowing the touch pad to be used as a keyboard for inputting numbers and/or providing hot-key functions.
