Abstract: A method for adjusting a backlight and a device for adjusting a backlight are provided. A parameter may be set as one of detectable physical quantities of the backlight. The physical quantity, for example, may be a current through a light emitting device, brightness of the light emitting device, or the like. An average value of the parameter is obtained according to values of the parameter which are detected in real time. When the average value is beyond a preset parameter range, a value of the voltage which is input to the light emitting device is adjusted, so that the current through the light emitting device is adjusted, and brightness of the backlight is adjusted. Thereby, brightness of the backlight can be adjusted in different ways, so that brightness of the backlight can be stable in different environments.
