Abstract
(EN) Disclosed in some implementations of the present application are a display device and a projection assembly correction method. The method comprises: when determining, according to image information of a projected image area and information of a reference area, that the projected image area is not an orthogonal projection state, calculating a projection area adjustment parameter according to a deviation value of the projected image area and the reference area, wherein the image information is information of an image of the image area projected by a projection assembly onto a screen and monitored by a monitoring assembly, when the projected image area is the orthogonal projection state, the projected image area coincides with the reference area, and the deviation value comprises a vertical deviation value and an angle deviation value; and adjusting a light exit angle of the projection assembly according to the projection area adjustment parameter, so that the projected image area coincides with the reference area.
(FR) Un dispositif d'affichage et un procédé de correction d'ensemble de projection sont divulgués dans certains modes de réalisation de la présente invention. Le procédé consiste à : lorsqu'il est déterminé, selon des informations d'image d'une zone d'image projetée et des informations d'une zone de référence, que la zone d'image projetée ne constitue pas un état de projection orthogonale, calculer un paramètre de réglage de zone de projection selon une valeur d'écart de la zone d'image projetée et de la zone de référence, les informations d'image étant des informations d'une image de la zone d'image projetée par un ensemble de projection sur un écran et surveillée par un ensemble de surveillance, lorsque la zone d'image projetée constitue l'état de projection orthogonale, que la zone d'image projetée coïncide avec la zone de référence, et que la valeur d'écart comprend une valeur d'écart vertical et une valeur d'écart d'angle ; et régler un angle de sortie de lumière de l'ensemble de projection selon le paramètre de réglage de zone de projection, de telle sorte que la zone d'image projetée coïncide avec la zone de référence.
