Abstract

A method for driving a display device comprises processing a plurality of sequent frame data by a graphics controller. The graphics controller is capable of optimizing a frame rate and outputting a first plurality of display signals at the frame rate. And then, a timing controller is used to convert the first plurality of display signals into a second plurality of signals at a predetermined refresh rate.

Description

technical field [0001] The present invention relates to a display device, in particular to a driving method of a display device (for example, a liquid crystal display (LCD)). Background technique [0002] Conserving power is a fundamental goal of electronics designers. For electronic equipment, such as notebook computers, its power consumption is the basic factor of its performance. A laptop's display and graphics card consume close to half of the energy consumed by the entire device. The development of energy-efficient display devices is an ongoing area of ​​interest for manufacturers of portable personal computers, such as the active pixel transistors included in thin-film transistor liquid crystal displays (TFT-LCDs), which communicate with the display The charge is stored at a switching frequency proportional to the refresh rate. Additionally, in the prior art, the graphics controller displays interface signals at a frequency proportional to the refresh rate of the dis...
