    • A display apparatus includes a display panel including nxm array of pixels and which sequentially drives the pixels from pixels in a first row to pixels in an n-th row, a panel driving circuit which sequentially applies first, second, third or fourth image data to the display panel, a backlight unit including a first light source disposed adjacent to the pixels in the first row and a second light source disposed adjacent to the pixels in the n-th row, and a backlight control circuit which divides each of first and second time periods into first, second, third and fourth blinking time periods, and applies a control signal to the backlight unit, where the first time period corresponds to two frames during which the first and second image data are applied, and the second time period corresponds to two frames during which the third and fourth image data are applied.
    • 显示装置包括:显示面板,其包括n×m个像素阵列,并且将第一行中的像素顺序地驱动到第n行中的像素;面板驱动电路,顺序地将第一,第二,第三或第四图像数据应用于 所述显示面板,包括邻近所述第一行中的像素布置的第一光源和与所述第n行中的像素相邻设置的第二光源的背光单元以及将第一和第二行中的每一个分隔开的背光控制电路 时间段转换为第一,第二,第三和第四闪烁时间段,并且将控制信号施加到背光单元,其中第一时间段对应于施加第一和第二图像数据的两个帧,并且第二时间段对应于 到其中应用第三和第四图像数据的两个帧。
