Abstract
Exemplary backlight driving method and display device are provided. The display device includes a light source array. The light source array includes a first group of light-emitting rows and a second group of light-emitting rows. The backlight driving method includes the steps of: firstly, receiving a gate driving frequency of the display device; subsequently, generating a backlight driving frequency according to the gate driving frequency; and afterwards, 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. 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.
