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.

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 apparatus for overdrive computation and method therefor. The overdrive computation apparatus is used for generating a desired overdrive gray-level value and includes first and second addition/subtraction devices, a priority encoder, and a computation device. The first addition/subtraction device outputs a difference value indicating difference between a first overdrive gray-level value OD1 and a second overdrive gray-level value OD2. The priority encoder determines a decision signal according to the difference value. The computation device receives first gray-level data, determines a first computation according to the decision signal, and performs the first computation on the first gray-level data to output operated gray-level data. The first gray-level data indicates a value lying between the ith first gray-level index value X(i) and the (i+1)th first gray-level index value X(i+1). The second addition/subtraction device receives the operated gray-level data and the first overdrive gray-level value OD1 to produce the desired overdrive gray-level value.
