However, when the above-mentioned high-contrast display device is turned off (no image display state), the display screen is very close to black.
Therefore, the display device in the non-image display state occupies the user's field of vision as a large black object against a bright wall surface, giving the user a sense of oppression.

Embodiment Construction

[0018] Embodiments of the present invention will be described in detail below with reference to the accompanying drawings.

[0019] (1) The overall structure of the TV set

[0020] figure 1 Shown is a television device as a display device to which the present invention is applied, which is composed of a tuning unit 3 , a display circuit 4 , a display unit 5 , and a processing unit 6 connected to a control unit 2 that collectively controls the television device 1 .

[0021] Part of the circuits in the control unit 2 work normally even when the television set 1 is turned off. According to the power-on operation input by the processing unit 6 or the remote controller 7, power is supplied to each part of the television set 1, and the television set 1 is turned on. 1 Switch (start) to the working state.

Abstract

The display device is provided with: an image display means; a dimmer means which is mounted on the display surface side of the image display means and selects either a concealment state to conceal the image display means or a transmissive state to transmit image light emitted from the image display means; and a dimmer control means to control the dimmer means to be in the transmissive state when the image display means is in the image display state and to control the dimmer means to be in the concealment state when the image display means is in the image display halting state. Thereby the feeling of pressure given to the user is reduced by concealing the image display means which is in the nearly black image display halting state with the dimmer means.

Description

technical field [0001] The present invention relates to a display device and a dimming device, which are suitable for, for example, television devices. Background technique [0002] In recent years, screens of display devices such as television devices tend to be larger in size. In addition, in display devices, in order to make dark images such as night scenes look more beautiful, the display contrast of the screen has been continuously improved (for example, refer to Patent Document 1: Japanese Unexamined Patent Publication No. 2003-234186). [0003] Here, when a display device having a large screen as described above is placed in a living room, it gives a sense of oppression to a user due to its large size. Generally, the walls of the living room are mostly bright colors such as white or beige. However, when the above-mentioned high-contrast display device is turned off (no image display state), the display screen is very close to black. Therefore, the display device in...
