摘要： An exemplary liquid crystal display includes a plurality of pixel units each including a pixel electrode for receiving data voltages and a common electrode for receiving a common voltage having a constant value. The data voltages applied to each pixel electrodes are equal a sum of a main data voltage having a square waveform and an auxiliary voltage that is periodically changed at intervals each formed by four continuous frames. An absolute value of the auxiliary voltage is less than a voltage difference between the main data voltage and the common voltage. A sum of the auxiliary voltage is zero in a minimum period.

摘要： A backlight adjusting system and method is adapted for adjusting a backlight brightness of a light emitting element for a display panel based on an ambient light around the display panel. The backlight adjusting system includes a first calculator, a processor and a driver. The first calculator calculates a target display brightness value of the display panel based on an actual ambient brightness value of the ambient light, a predetermined optimal ambient brightness value of the ambient light, and a predetermined optimal display brightness value of the display panel determined according to the predetermined optimal ambient brightness value. The processor obtains a target pulse duty value based on the target display brightness value. The driver generates a driving signal based on the target pulse duty value utilizing pulse width modulation techniques for driving the light emitting element so as to adjust the backlight brightness of the light emitting element.

摘要： An exemplary liquid crystal display (LCD) provides data lines, gate lines, and pixel units arranged as a matrix array. A method for driving the LCD includes a step of analyzing and determining polarities of one column of the pixel units as determining pixels, thereby defining a first polarity group and a second polarity group, and a step of sequentially applying corresponding data signals to a part of the whole pixel units that are arranged at same rows with the first polarity group in a part of a period of a frame. Corresponding data signals are sequentially applied to the other part of the whole pixel units that are arranged at same rows with the second polarity group in another part of a period of a frame.
