Abstract
(EN) A display device is disclosed. The display device of the present invention comprises: a display panel; a frame positioned at the back of the display panel; a main optical assembly positioned on the frame between the display panel and the frame; and a side optical assembly positioned on the frame between the display panel and the frame, and positioned adjacent to the main optical assembly, wherein the frame comprises: a bottom forming a bottom surface; and a side support extending from the bottom toward one side of the display panel, wherein: the side support is closer to the display panel than the bottom; the main optical assembly is positioned on the bottom; and the side optical assembly can be positioned on the side support.
(FR) La présente invention concerne un dispositif d'affichage. Le dispositif d'affichage de la présente invention comprend : un panneau d'affichage ; un cadre positionné à l'arrière du panneau d'affichage ; un ensemble optique principal positionné sur le cadre entre le panneau d'affichage et le cadre ; et un ensemble optique latéral positionné sur le cadre entre le panneau d'affichage et le cadre, et positionné de manière adjacente à l'ensemble optique principal, le cadre comprenant : un fond formant une surface inférieure ; et un support latéral s'étendant depuis le fond vers un côté du panneau d'affichage : le support latéral est plus proche du panneau d'affichage que le fond ; l'ensemble optique principal est positionné sur le fond ; et l'ensemble optique latéral peut être positionné sur le support latéral.
