摘要： A driving method for reducing the color shift suitable for driving a display panel is disclosed. The display panel includes at least one scan line, at least one data line, and at least one pixel unit electrically connected to the scan line and the data line. The driving method includes the following steps. First, turn on the pixel unit by the scan line during a frame period. Transmit a frame signal to the pixel unit by the data line during the frame period as the pixel unit is turned on. Turn on the pixel unit by the scan line between the present frame period and the next frame period. Transmit a revising signal to the pixel unit by the data line between the present frame period and the next frame period as the pixel unit is turned on, so as to reduce the color shift of the pixel unit.

摘要： A backlight controller, a display device using the same and a method for controlling a backlight module are provided. The backlight controller includes a temporal weighting module and a dimming controlling module. The temporal weighting module calculates a weight sum of a first backlight luminance provided in a current frame and a target backlight luminance to serve as an adjusted backlight luminance. The target backlight luminance is obtained according to an image content of the current frame. The dimming controlling module increases or decreases the adjusted backlight luminance by a step value according to the target backlight luminance and generates a second backlight luminance provided in a next frame. Therefore, a backlight luminance of the backlight module not only can be smoothly adjusted to the target backlight luminance at high speed for avoiding backlight flicker, but also can be adaptive to image content for saving electric power consumption.

摘要： A timing controller including a memory and a memory controller is provided. The memory includes an odd-field block and an even-field block. The memory controller is coupled to the memory and controls the memory. When two of a first, a second and a third gate output enable signals output by the timing controller are active, the memory is controlled to output the data of the (I−1)th scan line stored in the odd-field block. When one of the first, the second and the third gate output enable signals output by the timing controller is active, and the other two signals are inactive, the memory is controlled to output the data of Jth scan line stored in the even-field block and write an odd-field field data of the (J+1)th scan line to the odd-field block and write an even-field field data of the (J+1)th scan line to the even-field block.
