Description

  The present invention relates to a flat panel display having a thin and flat panel such as a liquid crystal panel or a plasma panel, and more particularly to the arrangement of operation buttons, a remote control light receiving unit, a brightness sensor, an LED (light emitting diode), and the like.

  Recently, a television receiver that receives a television broadcast program has generally used a thin and flat panel (that is, a flat panel) using liquid crystal or plasma for a display screen.

  In such a television receiver, the flat panel is provided with a remote control receiver for receiving infrared light accompanying the operation from a remote controller (hereinafter referred to as a remote controller), and various controls and adjustments in the receiver are performed in accordance with the operation of the remote controller. At the same time, this flat panel display device is also equipped with a power button, channel switching, volume control, screen brightness control, and other control buttons. Various controls and adjustments can be performed by operating the operation buttons.

  Conventionally, the remote control light receiving unit and various operation buttons have been provided at different locations on the panel (see, for example, Patent Document 1), but a technique in which these are arranged together has also been proposed.

  As an example of this, the power button is made of a transparent resin, and the power switch is switched by pushing the power button, but the remote control light receiving unit receives infrared rays from the remote control through the transparent power button. A technique that can be used has also been proposed (see, for example, Patent Document 2).

  As another example, an operation button for channel switching or image quality adjustment is installed in a recess of the cabinet, a door is provided in the recess, and the operation button can be operated by opening this door. A technique has also been proposed in which the operation button is hidden by closing the door so that it cannot be seen (see, for example, Patent Document 3).

  Furthermore, as another example, operation units such as a power button and a volume adjustment button are provided so as to be movable on the television set, and can be used by pulling this operation unit forward from the television set. There has also been proposed a technique of pushing into a holder provided in a television set (see, for example, Patent Document 4).
