Abstract:
(EN) A display device comprises: a display unit including a plurality of transparent display elements; a transmission color control unit provided on the rear side of the display unit and including a plurality of transmission color controlling elements that correspond to pixels; and a driver circuit that writes video signals into the display element and writes control signals corresponding to the video signals into the transmission color controlling elements. The transmission color controlling elements control the color of light transmitted by each pixel in accordance with the control signals. The transmission color controlling elements may include: a red absorbing layer which changes the transmittance of red light in accordance with a red control signal; a green absorbing layer which changes the transmittance of green light in accordance with a green control signal; and a blue absorbing layer which changes the transmittance of blue light in accordance with a blue control signal. Each absorbing layer may employ guest-host liquid-crystal elements that have dye molecules as guest molecules. Thereby, the present invention provides a see-through display that facilitates recognizing a displayed image even when the image is presented with a bright background.
(FR) Le dispositif d'affichage selon l'invention comprend : une unité d'affichage comprenant une pluralité d'éléments d'affichage transparents ; une unité de commande de couleur de transmission, qui se situe sur le côté arrière de l'unité d'affichage et comprend une pluralité d'éléments de commande de couleur de transmission correspondant à des pixels ; et un circuit d'attaque, qui écrit des signaux vidéo dans l'élément d'affichage et écrit des signaux de commande correspondant aux signaux vidéo dans les éléments de commande de couleur de transmission. Les éléments de commande de couleur de transmission commandent la couleur de la lumière transmise par chaque pixel en fonction des signaux de commande. Les éléments de commande de couleur de transmission peuvent comprendre : une couche absorbant le rouge, qui fait varier le facteur de transmission de la lumière rouge conformément à un signal de commande du rouge ; une couche absorbant le vert, qui fait varier le facteur de transmission de la lumière verte conformément à un signal de commande du vert ; et une couche absorbant le bleu, qui fait varier le facteur de transmission de la lumière bleue conformément à un signal de commande du bleu. Chaque couche absorbante peut employer des éléments cristaux liquides de type invité-hôte qui comportent des molécules de colorant en tant que molécules invitées. La présente invention concerne ainsi un affichage transparent qui facilite la reconnaissance d'une image affichée, même lorsque l'image est présentée avec un arrière-plan clair.
(JA) 表示装置は、複数の透明な表示素子を含む表示部と、画素に対応する複数の透過色制御素子を含み、表示部の背面側に設けられた透過色制御部と、表示素子に映像信号を書き込み、透過色制御素子に映像信号に応じた制御信号を書き込む駆動回路とを備える。透過色制御素子は、制御信号に応じて画素ごとに光の透過色を制御する。透過色制御素子は、赤色制御信号に応じて赤色光の透過率が変化する赤吸収層と、緑色制御信号に応じて緑色光の透過率が変化する緑吸収層と、青色制御信号に応じて青色光の透過率が変化する青吸収層を有していてもよい。各吸収層には、ゲスト分子として色素分子を有するゲストホスト液晶素子を用いてもよい。これにより、表示画面の後方が明るいときでも表示画像を認識しやすいシースルーディスプレイを提供する。
