Display apparatus

Abstract

A display apparatus may include a display device including a display panel and a back cover on a rear surface of the display panel, and a curvature variation device at the back cover to vary a curvature of the display device, the curvature variation device may include an arc member at a rear region of the display device parallel to a first direction, a supporting plate at the rear region of the display device, a rotation driver on the supporting plate, a linear gear on the supporting plate to perform a rectilinear motion, a rotation link part coupled to a center portion of the arc member on the supporting plate to rotate the center portion of the arc member based on a rectilinear motion of the linear gear, and a holder part rotatably supporting the center portion of the arc member on the supporting plate.

[0001] Cross References to Related Applications [0002] This application claims the benefit and priority of Korean Patent Application No. 10-2020-0086902 filed on July 14, 2020, the entire contents of which are incorporated herein by reference. technical field [0003] The present disclosure relates to display devices, and more particularly, to a curved display device. Background technique [0004] As the information society advances, various demands on display devices for displaying images are also increasing. Recently, as the display screen of each display device is enlarged into a flat type, there is a problem that the deviation between the viewing distance to the central area of ​​the screen and the viewing distance to each of the areas on both sides of the screen increases. [0005] In order to reduce viewing distance deviation and maximize user's immersion in viewing images, a curved display device has been proposed in which a flat display panel is curved with a cert...

Problems solved by technology

[0006] Also, in the related art curved display device, since the sound output from the sound device for outputting the sound associated with the image propagates in the forward direction or the downward direction with respect to the display panel, the sound quality may be due to the degraded by interference between sounds reflected from the ground, so it may be difficult to deliver sound accurately and may reduce immersion for the viewer

[0007] Therefore, in the curved display device of the related art, the user's immersion in viewing images can be maximized through the screen curved with a specific curvature, but it may be difficult to accurately transmit sound, resulting in a decrease in the user's acoustic immersion.
