Problems solved by technology

According to this constitution, if the user determines the desired brightness that the user feels is most suitable for viewing when the display is not in the automatic brightness adjustment mode, the user must go through complicated OSD operations including a plurality of steps to change the desired brightness to Low brightness with high power-saving effect, thus causing considerable inconvenience to users
[0011] Also, if the display is set to a low enough brightness for high power savings when the display is not in auto-brightness mode, it may be desirable to increase the determined The user of the brightness also has to go through the OSD operation, which causes inconvenience to the user

Abstract

To improve the convenience of users and facilitate a change into a luminance control mode high in power save effect, the display device includes a luminance control unit for controlling a luminance of the display unit in a luminance control mode selected from a first luminance control mode in which the luminance of the display unit is changed according to the ambient luminance detected by the sensor, a second luminance control mode in which the luminance is maintained at a predetermined luminance previously determined and a third luminance control mode in which the luminance is maintained at a minimum luminance; a first operating unit being operated to change the luminance control mode; and a change controlling unit for changing the luminance control mode, in which the luminance control unit currently controls the luminance of the display unit, responsive to operating the first operating unit.

Description

technical field [0001] The present invention relates to a technique of adjusting the brightness of a display such as an LCD (Liquid Crystal Display) incorporated in a display device. Background technique [0002] In a conventional display device including a display such as a liquid crystal display, the user who intends to change the brightness of the display to a preferred brightness that the user feels comfortable to look at needs to refer to the OSD (On-Screen Display) for many devices mounted on the display device. Operate the operation buttons to adjust the brightness. [0003] Recently, some liquid crystal display devices and liquid crystal televisions incorporate a brightness sensor and have a function of automatically adjusting (the brightness of) the display to an appropriate brightness according to the ambient brightness detected (measured) by this sensor. [0004] However, the conventional liquid crystal display device or the like requires an OSD operation to canc...
