Claim 0:
1. A display device, wherein the display device is a wearable display device, and comprises: a controller, a display module, a temperature sensor disposed in the display module, and a data interface; wherein
the controller is connected to the display module and the temperature sensor;
the temperature sensor is configured to detect a temperature of the display module;
the data interface is configured to receive a display signal from a mobile terminal, and send the display signal to the controller; and
the controller is configured to:
adjust a gamma parameter of the display module to a target gamma parameter corresponding to the temperature of the display module;
determine a target drive voltage required by the display module with the target gamma parameter; and
drive, based on the display signal and the target drive voltage, the display module to display an image; wherein
the display module has a preset initial gamma parameter, wherein a luminance of the display module corresponding to the initial gamma parameter is a first luminance, and a luminance of the display module corresponding to the target gamma parameter is a second luminance, a difference between the first luminance and the second luminance is less than a luminance threshold;
the controller is further configured to: send a temperature detect instruction to the temperature sensor once at an interval, wherein the interval is pre-stored in the controller; and again adjust the target gamma parameter corresponding to the temperature of the display module in the case that the temperature of the display module is decreased and a temperature range which a temperature acquired by the controller at a current time is within is lower than a temperature range which a temperature acquired by the controller at a previous time is within, wherein a corresponding relationship of the temperature range and the gamma parameter is stored in the controller; and
the temperature sensor is further configured to detect the temperature of the display module once at the interval in response to the temperature detect instruction.
