Abstract
The present disclosure provides a head-mounted display device including a first OLED display, a first temperature sensor, and a controller. The first OLED display is configured to display image data. The first temperature sensor is disposed within the head-mounted display device and is configured to sense the first device temperature of the first OLED display. The controller is electrically connected to the first OLED display and the first temperature sensor. The controller outputs the image data and a first display driving voltage to the first OLED display. The controller adjusts the first display driving voltage to control the brightness performance of the first OLED display according to the change of the first device temperature.

A head-mounted display device, comprising:
- a first OLED display, configured to display image data;
- a first temperature sensor, disposed within the head-mounted display device, and configured to sense a first device temperature of the first OLED display;
- and
- a controller, electrically connected to the first OLED display and the first temperature sensor, outputting the image data and a first display driving voltage to the first OLED display, and adjusting the first display driving voltage according to the change of the first device temperature to control a brightness performance of the first OLED display;
- wherein when the first device temperature is equal to a predetermined temperature, the first display driving voltage is a preset voltage;
- when the first device temperature is higher than the predetermined temperature, the controller decreases the first display driving voltage;
- and when the first device temperature is lower than the predetermined temperature, the controller increases the first display driving voltage.
A brightness control method for a head-mounted display device which comprises a first OLED display, a first temperature sensor and a controller, the method comprising:
- outputting image data to the first OLED display by the controller to display the image data;
- sensing the first device temperature of the first OLED display by the first temperature sensor;
- outputting a first display driving voltage to the first OLED display by the controller, and adjusting the first display driving voltage according to the change of the first device temperature to control the brightness performance of the first OLED display;
- wherein the head-mounted display device further comprises a second OLED display and a second temperature sensor, the method further comprising:
- outputting the image data to the second OLED display by the controller to display the image data;
- sensing the second device temperature of the second OLED display by the second temperature sensor;
- outputting the second display driving voltage to the second OLED display by the controller, and adjusting the second display driving voltage according to the change of the second device temperature to control the brightness performance of the second OLED display so that the brightness performance of the first and second OLED displays is consistent.
