Abstract: A display driving apparatus and a multi-line inversion driving method thereof are provided. The apparatus includes a gate driver, a source driver, a gate enabling unit and a line polarity signal unit. Every time after a plurality of scan lines is turned on, the source driver inverts the polarity of the sub pixel driving signal according to a line polarity signal output by the line polarity signal unit. Thereby, the polarity inversion operating frequency of the sub pixel driving signal is lowered to reduce the power consumption of the source driver.

The structure of adjusting voltage with speed has a logic speed monitoring unit, an internal logic voltage generator, a substrate voltage generator, a substrate leakage-current monitoring unit, and a power management control unit. In this manner, by monitoring the logic operation speed of an internal logic circuit in the source driver, in accordance with the change of the operation frequency, the power is dynamically adjusted, so as to optimize a condition between the power consumption and the operation speed. And, in the standby mode, the power consumption is further reduced by adjusting the substrate voltage.

Abstract: A wireless system broadcasts data in frames, each frame having F slots. Output from a matched filter is used to combine K slots to generate profile data, where K is less than F. N peak values respectively from n peak positions are selected from the profile data, where n is greater than one. A correlator is employed, together with the n peak positions and S slots subsequent the K slots, to generate n×S correlation values. Respective combination values for the n peak positions are generated by coherently combining the correlation values, and combining the coherent combination results with the non-coherent n peak values. The combination values are respectively used to generate SNR values for each of the n peak positions. The peak position having the best respective SNR value is then selected as a slot synchronization position.

Abstract: A source driver and an internal data transmission method are provided. The present invention employs specially designed switch units and creates specially designed data paths in a source driver, which matches with the driving method for dot invesion and the specially designed pixel array. When the dot inversion driving method is used on a pixel array of a specific design, each output buffer and digital-to-analog converter inside the source driver continuously output voltages of positive polarity and voltages of negative polarity, instead of switching between positive and negative polarities. Consequently, the swing voltages that the source driver outputs can be lowered, the power consumption can also be reduced accordingly, a smaller area is occupied, and the costs are reduced.
