Embodiment Construction

[0026] The present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the present invention, but not to limit the present invention. In addition, it should be noted that, for the convenience of description, only some structures related to the present invention are shown in the drawings but not all structures.

[0027] figure 1 It is a structural schematic diagram of a backlight module in the prior art. The curved surface backlight module includes a backplane 11 and a lamp board 12 attached to the backboard 11, and a plurality of light sources 121 on the lamp board 12. Because the existing curved surface backlight module is formed by a curvature mold, or is bent into a curved surface through a flat back panel, the flexible light panel 12 is formed by bonding the flat light panel and the curved back panel to form a curved ...

Abstract

The invention discloses a curved surface backlight module and a display device. The curved surface backlight module comprises a curved surface back plate and a curved surface lamp panel; the curved surface back plate comprises a first curved surface and a second curved surface which are opposite to each other; the first curved surface is arranged close to the light emitting side of the curved surface backlight module; the curved surface lamp panel is formed by bending an initial lamp panel; a plurality of light sources arranged on the curved surface lamp panel in an array mode are fixed to thefront surface of the curved surface lamp panel through bonding pads; the back surface of the curved surface lamp panel is arranged close to the first curved surface of the curved surface back plate;at least one groove is formed in the front surface of the curved surface lamp panel; and the grooves are arranged in a lamp panel gap area between the adjacent light sources. According to the curved surface backlight module and the display device, the problems that the bonding pads easily fall off and the light sources are easily damaged due to the fact that the lamp panel of an existing curved surface backlight module is bent can be solved.

Description

technical field [0001] The invention relates to the field of display technology, in particular to a curved surface backlight module and a display device. Background technique [0002] With the development of science and technology, display devices are widely used in daily life and work. Currently, display panels in display devices are mostly liquid crystal display panels. As the demand for curved screens becomes more and more strong, the backlight module of the full screen can be a curved backlight module, which is convenient to present a wider viewing angle and obtain better display effects. The above-mentioned curved screen is especially suitable for vehicle-mounted display devices, which facilitates the installation of large-size display screens and can be installed in instrument panels, car roofs, and seat backs. [0003] The backlight module includes the backplane and the lamp board attached to the backplane. The backplane of the curved surface backlight module is form...
