[0042] figure 1 A schematic structural diagram of a liquid crystal display device with a curved backlight module provided by the first embodiment of the present application is shown.

[0043] like figure 1 As shown, the first embodiment of the present application provides a liquid crystal display device, including a liquid crystal display panel 2 and a backlight module 1 arranged on the side of the backlight surface of the liquid crystal display panel 2, and the backlight module 1 is used to illuminate the liquid crystal display panel. 2 provide a light source.

[0044] The liquid crystal display panel 2 can be a single display panel, or a double display panel stacked in the thickness direction. When the liquid crystal display panel 2 is a dual display panel, the display panel located at the bottom layer is used for light control, and the display panel located at the top layer is used for displaying. Such setting can improve the contrast ratio of the liquid crystal display d...

Abstract

The invention relates to a backlight module and a liquid crystal display device. The backlight module comprises a backlight plate, a light-emitting assembly and an optical assembly, the light-emitting assembly is located on the backlight plate and comprises a lamp panel and a plurality of light-emitting elements arranged on the lamp panel, the optical assembly is located on the side, away from the backlight plate, of the light-emitting assembly, the backlight plate and the optical assembly are both curved-surface pieces, and the curved-surface backlight module further comprises a curved-surface supporting piece. The curved surface supporting piece is arranged between the backlight plate and the lamp plate and connected with the lamp plate and the backlight plate so that the curvature radius of the lamp plate can be kept consistent with the curvature radius of the backlight plate. According to the backlight module, the curved surface supporting piece is arranged between the backlight plate and the lamp panel of the light-emitting assembly to ensure the curvature consistency of the lamp panel and the backlight plate, so that the light mixing distances between all the light-emitting elements and the liquid crystal display panel are the same, and the problem that the liquid crystal display panel is uneven in display is solved.

Description

technical field [0001] The present application relates to the field of display technology, in particular to a backlight module and a liquid crystal display device. Background technique [0002] With the development of display technology, curved liquid crystal display devices emerge 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] A curved liquid crystal display device generally includes a curved liquid crystal display panel (LCD for short) and a curved backlight module. The curved backlight module is used to provide a light source for the curved LCD so that the curved LCD displays images. The curved backlight module includes a backlight panel and a light panel attached to the backlight panel. The backlight panel is formed by a curved surface mold an...
