Abstract: There is provided a display device which includes a display panel, a backlight that has a plurality of light sources and applies light to the display panel, a human body detector configured to detect a human body located around the display panel, a human body information acquisition unit configured to acquire information on the human body, and a control that controls an operation of a user recognition unit when the human body is detected in a standby mode, performs user recognition based on the acquired human body information, controls an operation of the display panel such that notification information of the user is displayed in a portion of the display panel, and turns some light sources out of the plurality of light sources on. According to the invention, for the user who views the display device, the local dimming is performed on the backlight which provides content information desired by the user utilizing only a portion of the display device. Therefore, it is possible to increase dynamic contrast and reduce power consumption more than in global dimming. Accordingly, the user may enter a personalized mode of a TV, and content information is provided to the user in the standby mode.

Abstract translation: 提供了一种显示装置，其包括显示面板，具有多个光源并向显示面板施加光的背光源，构造成检测位于显示面板周围的人体的人体检测器，人体信息采集 被配置为获取关于人体的信息的单元，以及当在待机模式中检测到人体时控制用户识别单元的操作的控制，基于获取的人体信息执行用户识别，控制显示器的操作 面板，使得用户的通知信息被显示在显示面板的一部分中，并且从多个光源中的一些光源开始转动。 根据本发明，对于观看显示设备的用户，在背光源上执行局部调光，该背光源仅提供用户仅使用显示设备的一部分所期望的内容信息。 因此，与全局调光相比，可以增加动态对比度并降低功耗。 因此，用户可以进入电视的个性化模式，并且在待机模式中向用户提供内容信息。
