Abstract

The invention provides a backlight module.The backlight module comprises a frame, an arc-shaped light guide plate and backlight lamp strips.Each backlight lamp strip comprises a substrate and a plurality of lamp sources.The surfaces of the substrates are arc-shaped surfaces.The light guide plate is provided with two opposite curved edges.The curvature of the arc-shaped surfaces is identical to that of the curved edges.The lamp sources are arranged on the arc-shaped surfaces.The arc-shaped light guide plate and the backlight lamp strips are contained in the frame.Each backlight lamp strip is located on one side of the corresponding curved edge of the light guide plate.The light-out sides of the lamp sources face the light guide plate.The invention further provides a display device.

Description

technical field [0001] The invention relates to the technical field of liquid crystal display, in particular to a backlight module and a display device. Background technique [0002] With the development of technology, the user's requirements for the appearance and performance of the display device can no longer be satisfied with the traditional flat structure. Currently, a curved structure appears on the market to meet the ergonomic design requirements and improve the user's visual and tactile comfort. The composition structure of the display device with a flat structure is the same, and the display device with a curved surface includes a display panel, a backplane, a front frame, a plastic frame, and a backlight, and the curved surface backlight adopts a side-emitting LED (Light emitting diode). Such as figure 1 , where the display panel (not shown), the back panel 1, the light guide plate 2 and the optical film 3 groups are all curved structures with the same curvature, ...
