Abstract: A display device includes an image receiving unit, a power-saving control device, a display control unit, and a backlight module control unit. The power-saving control device judges whether or not received frames are still for a predetermined time. If the power-saving control device judges that the received frames are still for the predetermined time, the power-saving control device outputs a first control signal to the display control unit for controlling the display panel to perform power saving to reduce its power consumption while continuing displaying frames, and the backlight module control unit controls the backlight module to continue providing the backlight; while if the received frames are not still or are still for a time shorter than the predetermined time, the power-saving control device does not output the first control signal to the display control unit for controlling the display panel to perform power saving to reduce its power consumption.

Abstract translation: 显示装置包括图像接收单元，省电控制装置，显示控制单元和背光模块控制单元。 节电控制装置判断接收帧是否仍然在预定时间。 如果节电控制装置判定接收帧仍然在预定时间内，则省电控制装置向显示控制单元输出第一控制信号，以控制显示面板进行功率节省以降低其功耗，同时 继续显示帧，并且背光模块控制单元控制背光模块以继续提供背光; 而如果接收到的帧不是静止时间还是比预定时间短的时间，则省电控制装置不向显示控制单元输出第一控制信号，以控制显示面板进行省电以减少其 能量消耗。
