To provide a directional backlit display device which allows an observer to view the entire image at various positions.SOLUTION: A directional backlit display device includes a light source module 1, a reflective narrow-angle diffuser 2, a backlit type display panel 3, an eye tracking device 5 and a controller 6. The diffuser 2 includes a shaft 22 and is utilized to reflect and uniformly diffuse the light to provide a uniform directional light beam. The backlit type display device panel 3 is included on a projecting optical path of the uniform directional light beam. The uniform directional light beam illuminates an image displayed on the backlit type display device panel 3 and projects to a projection area. The controller 6 receives eye position information from the eye tracking device 5 and calculates a coordinate. The controller 6 calculates a corrective projection area when the coordinate deviates from the projection area, and the drive module 4 rotates the reflective narrow-angle diffuser 2 around an axis of the shaft 22 according to the corrective projection area, so the image projection area moves with the eye.SELECTED DRAWING: Figure 6

    【課題】観察者が様々な位置で画像全体が見える指向性バックライトディスプレイ装置を提供する。【解決手段】指向性バックライトディスプレイ装置は、光源モジュール1、反射性狭角拡散体2、バックライト型ディスプレイパネル3、視線追跡装置5、およびコントローラ6を備え、拡散体2はシャフト22を含み、光を反射して均一に拡散して均一な指向性光ビームを提供し、バックライト型ディスプレイ装置パネル3は均一な指向性光ビームの投影光路上にあり、均一な指向性光ビームはバックライト型ディスプレイ装置パネル3に表示される画像を照射して投影領域に投影し、コントローラ6は視線追跡装置5から目の位置情報を受け取って座標を算出し、コントローラ6は座標が投影領域からずれると補正投影領域を算出し、駆動モジュール4は補正投影領域に応じて反射性狭角拡散体2をシャフト22の軸周りに回転させ、それによって画像投影領域は目と一緒に動く。【選択図】図6
