Abstract:
(EN) Therefore, it is an aspect of the present disclosure to provide a back light apparatus realizing a two-dimensional (2D) image and a three-dimensional (3D) image with no glasses by using one light guide plate, a display apparatus including the same, and a method of controlling the display apparatus. Additional aspects of the disclosure will be set forth in part in the description which follows and, in part, will be obvious from the description, or may be learned by practice of the disclosure. In accordance with one aspect of the present disclosure, a back light apparatus comprising: a plurality of light sources configured to generate light; and a light guide part configured to change a path of the generated light and emit the light; wherein the light guide part comprises: a light guide plate configured to change the path of the generated light and emit the light; a first pattern part disposed on one surface of the light guide plate and configured to emit the light in a first direction; and a second pattern part disposed on one surface of the light guide plate and configured to emit the emitted light in a second direction.
(FR) Par conséquent, la présente invention concerne un appareil de rétroéclairage qui réalise une image bidimensionnelle (2D) et une image tridimensionnelle (3D) image sans lunettes au moyen d'une plaque guide de lumière, un appareil d'affichage comprenant celle-ci, et un procédé de commande de l'appareil d'affichage. Des aspects supplémentaires de la divulgation seront exposés en partie dans la description qui suit et, en partie, seront évidents à partir de la description, ou peuvent être appris par la mise en pratique de la description. Selon un aspect de la présente invention, un appareil de rétroéclairage comprend : une pluralité de sources de lumière configurées pour générer de la lumière; et une partie de guidage de lumière configurée pour modifier un trajet de la lumière générée et émettre la lumière; la partie de guidage de lumière comprenant : une plaque guide de lumière configurée pour modifier le trajet de la lumière générée et émettre la lumière; une première partie de motif disposée sur une surface de la plaque guide de lumière et configurée pour émettre la lumière dans une première direction; et une seconde partie de motif disposée sur une surface de la plaque guide de lumière et configurée pour émettre la lumière émise dans une seconde direction.
