Patent ID: 8581940

Claim:
A display device comprising: a display panel having a plurality of pixels; a drive circuit supplying a drive voltage to the plurality of pixels; a display control device supplying display data to the drive circuit; a temperature detecting sensor; and a display bit reduction circuit, wherein a high-temperature operation mode is set by the temperature detecting sensor in the case where a temperature equal to or more than a predetermined temperature is detected, the display bit reduction circuit configured to supply only the highest-order bit of display data as a control signal to the drive circuit in the high-temperature operation mode to reduce power consumption of the display device to suppress a rise in temperature of the display device in the high-temperature operation mode, the drive circuit includes an amplifier circuit which outputs a gray scale voltage based on display data, and an output inverter which sets one power supply voltage to a maximum gray scale voltage and sets another power supply voltage to minimum gray scale voltage, and a control signal line electrically connected between the display bit reduction circuit and the drive circuit to transmit the control signal to the drive circuit to stop operation of the amplifier circuit and to connect the output inverter to an output of the drive circuit when the display device is in the high-temperature operation mode.
