Patent ID: 8581829

Claim:
A backlight driving method adapted to a display device, the display device comprising a light source array constituted by a plurality of light-emitting diodes arranged in an array, the light source array comprising a first group of light-emitting rows and a second group of light-emitting rows, each of the light-emitting rows being constituted by a plurality of light-emitting diodes in a row; the backlight driving method comprising steps of: receiving a gate driving frequency of the display device; generating a backlight driving frequency, according to the gate driving frequency; and sequentially providing a first row driving voltage to the first group of light-emitting rows in a first time period and sequentially providing a second row driving voltage to the second group of light-emitting rows in a second time period, according to the backlight driving frequency; wherein the first time period and the second time period have different phases from each other, and the gate driving frequency is different from the backlight driving frequency.
