Abstract: A data access method for a timing controller of a flat panel display includes forming a line buffer including a plurality of memory cells in the timing controller, dividing the plurality of memory cells into a first section and a second section, wherein the number of memory cells in the first section is greater than the number of memory cells in the second section, writing a first number of pixel data into the first section, wherein the first number of pixel data is included in a plurality of pixel data corresponding to a row of a frame, writing a second number of pixel data into the second section, wherein the second number of pixel data is included in the plurality of pixel data, and the first number is equal to the second number, and reading the plurality of pixel data from the plurality of memory cells according to an order.

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.

Abstract: A display device capable of saving memory storage used for an overdriving function includes a compression unit, a frame buffer, a decompression unit and a look-up table (LUT) unit. The compression unit includes a decimation filter and is used for compressing data of a received frame and reducing a size of the received frame, to generate a compression frame. The frame buffer is coupled to the compression unit and used for storing the compression frame. The decompression unit includes an interpolation filter and is used for decompressing data of the compression frame outputted by the frame buffer and reducing a size of the compression frame, to generate a decompression frame. The LUT unit is coupled to the decompression unit and used for comparing the decompression frame with a next received frame of the received frame to determine an overdriving voltage.
