摘要: An overdrive device for driving a display panel includes a comparison circuit, a multiplexer, and an overdrive module. The comparison circuit receives pixel values of display cells of the display panel in a previous frame carried on a first decompressed data signal and in a current frame carried on a second decompressed data signal, and determines whether the brightness/color of each target display cell is static to assert or de-assert a selection signal. The multiplexer outputs an output signal to output at least a reference pixel value for the overdrive module according to the selection signal. The overdrive module receives the reference pixel value, and overdrives the target display cell according to an overdrive value corresponding to a combination of the received current and reference pixel values stored in a look-up table of the overdrive module.

摘要: An energy-based oriented switching mode power supply includes a bi-directional converter having an energy input and a load output, and an energy based pulsed generator connected between the energy input and the load output for outputting a gate voltage signal controlling how much energy is supplied from the energy input. The energy based pulsed generator receives a clock signal and outputs the gate voltage signal according to the load output of the bi-directional converter when the clock signal is at a high level. Accordingly, the switching mode power supply achieves a hybrid of PWM and PFM, depending on the energy demand of the load output, for a fast transient response and a small voltage ripple whilst improving power efficiency over a wide load range.
