Display devices and methods for controlling display devices

Abstract

The invention relates to a display device and a method for controlling a display device. The display device consists of a display unit, a light sensor, a cooling fan, and a controller. The light sensor is configured to detect ambient light and generate a luminance value indicating the luminance of the ambient light. The cooling fan is configured to create fluid flow within the display unit. The controller is configured to monitor the luminance value over each time interval and control the cooling fan's rotation speed based on the luminance value.
