Embodiment Construction

[0024] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only some, not all, embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without making creative efforts belong to the protection scope of the present invention.

[0025] Embodiments of the present invention provide a light source assembly, such as Figure 2(a) with 2(b) As shown, the light guide plate 10 and the LED light bar 20 are included. The light guide plate 10 is a curved light guide plate, the LED light bar 20 is an arc light bar, and the curvature of the arc light bar matches the curvature of the curved light guide plate. Wherein, the curved light guide plate has a group of straight sides 101 parallel to each...

Abstract

An embodiment of the invention provides a light source assembly, a backlight module and a curved surface display device which belong to the technical field of display and are capable of enhancing light entering rate of a light guide plate in the curved surface display device and improving the uniformity of screen brightness. The light source assembly comprises a light guide plate and an LED (light-emitting diode) light bar; the light guide plate is a light guide plate with a curved surface; the LED light bar is an arc light bar; curvature of the arc light bar matches with that of the light guide plate with the curved surface; the light guide plate with the curved surface is provided with a group of mutually parallel straight edges and a group of curved edges with the same curvature; the arc light bar is arranged on one side of the curved edges of the light guide plate with the curved surface. The light source assembly, the backlight module and the curved surface display device are suitable for the manufacturing of display devices.

Description

technical field [0001] The invention relates to the field of display technology, in particular to a light source assembly, a backlight module and a curved display device. Background technique [0002] Traditional LCD (Liquid Crystal Display, liquid crystal display device) has always been unsatisfactory in displaying images at the edge of the screen. With the development of display technology, curved liquid crystal display devices have emerged as the times require. The entire screen of the curved liquid crystal display device is designed in a curved shape, which can provide a wide panoramic image effect, whether it is the center or the edge of the screen, it can provide users with the same visual enjoyment. [0003] At present, the curved liquid crystal display device mainly adopts two structures of a direct type backlight module and an edge type backlight module. Since the direct-type backlight module is not conducive to realizing thinner and lighter display devices, most c...
