前記スタンバイ状態のときは、前記開状態のときより前記光量を低減するように、前記制御手段により前記照明手段を制御することを特徴とする表示装置。 A display device that irradiates light from an illuminating unit onto a panel unit, projects light modulated by the panel unit onto a display unit by a projection lens, and displays an image.
A lens cover capable of moving the front surface of the projection lens;
Means for identifying a standby state in which the lens cover covers a part of the front surface of the projection lens and an open state in which the lens cover is open without covering the front surface of the projection lens;
Control means for controlling the amount of light from the illumination means,
In the standby state, the illumination unit is controlled by the control unit so as to reduce the amount of light compared to the open state .
前記投射レンズが開状態、待機状態及び閉状態となるように前記投射レンズの前面に移動可能に設けられ、前記閉状態において前記投射レンズからの光を遮光する機能を有するレンズカバーと、A lens cover that is provided movably on the front surface of the projection lens so that the projection lens is in an open state, a standby state, and a closed state, and that has a function of blocking light from the projection lens in the closed state;
前記表示装置の待機状態と前記表示装置の画像表示時における開状態とを識別する識別手段と、Identification means for identifying a standby state of the display device and an open state at the time of image display of the display device;
前記光源から出射する光量を制御する制御手段とを備え、Control means for controlling the amount of light emitted from the light source,
前記待機状態時の前記光源から出射する光量を、前記画像表示時における開状態時よりも低減するように制御することを特徴とする表示装置。A display device, wherein the amount of light emitted from the light source in the standby state is controlled to be smaller than that in the open state during the image display.
前記投射レンズをほぼ完全に覆う閉状態と前記投射レンズの前面を覆わずに開放している開状態との間を移動可能に設けられ、前記閉状態において前記投射レンズからの光を遮光する機能を有するレンズカバーと、A function that is movable between a closed state that almost completely covers the projection lens and an open state that is open without covering the front surface of the projection lens, and that blocks light from the projection lens in the closed state A lens cover having
前記レンズカバーに移動位置により、前記レンズカバーが前記投射レンズの一部を覆う一時休止状態と前記レンズカバーが前記投射レンズの前面を覆わずに開放している前記開状態とを識別する識別手段と、Identification means for discriminating between a temporarily resting state in which the lens cover covers a part of the projection lens and an open state in which the lens cover is opened without covering the front surface of the projection lens, depending on a movement position of the lens cover When,
前記光源を冷却するために風を送風するファンと、A fan that blows air to cool the light source;
前記投射レンズから投射する光量及び前記ファンの回転数を制御する制御手段とを備え、Control means for controlling the amount of light projected from the projection lens and the rotational speed of the fan,
前記一時休止状態時の前記投射レンズから投射する光量及び前記ファンの回転数を、前記開状態時よりもそれぞれ低減するように制御することを特徴とする表示装置。A display device, wherein the amount of light projected from the projection lens in the pause state and the rotational speed of the fan are controlled so as to be smaller than in the open state.
