摘要： It is an object of the present invention to provide a display panel driver with which power consumption can be reduced. The display panel driver includes a pixel data pulse generation circuit which generates pixel data pulses by connecting the column electrodes and a power source line in accordance with the pixel data to apply the pixel data pulses to the column electrodes, and a resonance pulse power circuit which generates a resonance pulse power source voltage to apply the resonance pulse power source voltage to the power source line, the resonance pulse power circuit changing the resonance amplitude of the resonance pulse power source voltage while keeping a maximum voltage of the resonance pulse power source voltage in accordance with a pattern of a pulse sequence of the pixel data pulses. A predicted power consumption of the resonance pulse power circuit is determined based on the pixel data for one field, and the pixel data pulse generation circuit is controlled so as to adjust the power consumption of the resonance pulse power circuit in accordance with the predicted power consumption.

摘要： Prepared is brightness frequency data that indicates the number of pixels, having the same brightnesses in a brightness distribution for each of the fields represented by an input image signal. Based on the brightness frequency data, the number of subfields for emission at each brightness in a brightness region is adjusted for each of at least two brightness regions. As a result, the greater the frequency indicating the total number of pixels at each of the same brightnesses in a brightness region, the larger the number of subfields allocated to that brightness region. Therefore, satisfactory grayscale representation suitable to human visual characteristics is achieved.

摘要： A video signal processing apparatus which performs a frame-rate conversion of a progressive line-scan video signal based on a film source of M film frames per second (wherein M is a natural number) into a video signal in which a same film frame is repeated N times for each 1/M second, and mixes, frame by frame, a video signal of a preceding frame and a video signal of a following frame of the converted progressive line-scan video signal. Thus, the display quality of telecine-converted images can be improved.
