    • 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.
    • 提供了示例性背光驱动方法和显示装置。 显示装置包括光源阵列。 光源阵列包括第一组发光行和第二组发光行。 背光驱动方法包括以下步骤:首先,接收显示装置的栅极驱动频率; 随后根据门驱动频率产生背光驱动频率; 之后,在第一时间段内顺序地向第一组发光行提供第一行驱动电压,并且在第二时间段内依次向第二组发光行提供第二行驱动电压,根据 背光驱动频率。 第一时间段和第二时间段具有彼此不同的相位,并且栅极驱动频率与背光驱动频率不同。
