Patent ID: 8878764

Claim:
A driving method for reducing power consumption of a liquid crystal display (LCD), the method comprising: sequentially receiving first data, third data, second data and fourth data; determining whether the second data is the same as the first data and whether the third data is the same as the fourth data; generating a control signal without a first horizontal start signal (STH) and a second horizontal start signal for a data-line driving circuit, when the second data is the same as the first data and the fourth data is the same as the third data; generating a driving signal without driving data, when the second data is the same as the first data and the fourth data is the same as the third data; and controlling the data-line driving circuit to selectively read in the driving data according to the control signal and the driving signal; wherein the first data and the second data are image data of a first source driver of the data-line driving circuit corresponding to two adjacent scan-lines, the third data and the fourth data are image data of a second source driver of the data-line driving circuit corresponding to the two adjacent scan-lines, the first horizontal start signal corresponds to the first source driver, and the second horizontal start signal corresponds to the second source driver.
