Patent ID: 11004374

Abstract:
A low-power display device in which an operation method is optimized in accordance with the resolution and the frame frequency of a content is provided.The display device includes a display unit and an image receiving apparatus. In the case where the resolution of a content is lower than the resolution that can be displayed by the display device, a source driver and a gate driver included in the display unit output signals to a plurality of source lines and gate lines, and the source driver and the gate driver are operated at lower operation frequencies. Furthermore, the power supply voltages of the logic circuit portions included in the source driver and the gate driver are lowered. In the case where the frame frequency of the content is lower than the frame frequency that can be displayed by the display device, the source driver and the gate driver included in the display unit are operated at lower operation frequencies, and power supply voltages of the logic circuit portions included in the source driver and the gate driver are lowered. The image receiving apparatus detects the resolution and the frame frequency of the content.
