    • The present invention relates to a method and a device for controlling a display device for power saving thereof. According to one embodiment of the present invention, the method for controlling a display device is to control luminance of a display unit to save power of the display device including the display unit for displaying a screen. The method for controlling a display device comprises the steps of: calculating first luminance which is current luminance in the display unit and second luminance which is to be changed in the display unit considering the constant K determined according to the Weber′s law; and changing the luminance to the second luminance in the display unit. According to one embodiment of the present invention, the screen brightness can be controlled based on a minimum brightness difference that a user can identify, thereby reducing power consumption of the display device while preventing the user from recognizing the brightness change in the display unit.
    • 本发明涉及一种用于控制用于省电的显示装置的方法和装置。 根据本发明的一个实施例,用于控制显示装置的方法是控制显示单元的亮度以节省包括用于显示屏幕的显示单元的显示装置的功率。 用于控制显示装置的方法包括以下步骤:考虑以韦伯定律确定的常数K,计算作为显示单元中的当前亮度的第一亮度和将在显示单元中改变的第二亮度; 以及在显示单元中将亮度改变为第二亮度。 根据本发明的一个实施例,可以基于用户可以识别的最小亮度差来控制屏幕亮度,从而降低显示设备的功耗,同时防止用户识别显示单元中的亮度变化。
