Problems solved by technology

[0002] There are generally two schemes for the backlight source in the display device, one is the side-type backlight structure ( figure 1 ) is applied to small-sized and thin products (about 10mm). (>65inch), all adopt the direct backlight structure ( figure 2 ), the backlight includes a backplane, a light source 3 arranged in the backplane, and a diffusion plate 4 arranged above the light source 3, and the thickness of a large-sized display device product is generally greater than 25mm due to the use of a direct-type backlight. It is not convenient for the thinning development of large-size display devices

Embodiment Construction

[0040] In order to facilitate the thinning development of large-size display devices, an embodiment of the present invention provides a backlight source and a display device. In the technical solution of the embodiment of the present invention, a backlight source and a display device are provided. The reflection sheet enables the backlight source of a large-size display device to adopt a side-entry type, thereby reducing the thickness of the backlight source and further reducing the thickness of the display device. In order to facilitate the understanding of the technical solution of the present invention, the technical solution of the present invention will be described in detail below in conjunction with the drawings and specific embodiments.

[0041] Such as image 3 as shown, image 3 A schematic structural view of the backlight provided by the embodiment of the present invention is shown.

Abstract

The invention relates to the technical field of display devices, and discloses a backlight and a display device. The backlight comprises a back plate, a reflector plate arranged in the back plate, a light source arranged on one side in the back plate, a reflector, and a diffuser plate. The light source is arranged on one side of a reflecting face of the reflector plate. The reflector is arranged on the side, opposite to the light source, in the back plate. The reflector is used for reflecting the light ray, irradiating on the reflector, of the light source to the reflector plate. The diffuser plate covers the light source and the reflector. According to the technical scheme, after the light ray irradiating through the light source irradiates on the reflector, the light ray is reflected to the reflector plate through the reflector and then reflected to the diffuser plate through the reflector plate, and then the purpose of light emitting is achieved. In the embodiment, the light source is arranged on one side of the back plate through cooperation of the reflector and the reflector plate, the thickness of the backlight is reduced accordingly, and then thinning development of the display device is facilitated.

Description

technical field [0001] The present invention relates to the technical field of display devices, in particular to a backlight source and a display device. Background technique [0002] There are generally two schemes for the backlight source in the display device, one is the side-type backlight structure ( figure 1 ) is applied to small-sized and thin products (about 10mm). (>65inch), all adopt the direct backlight structure ( figure 2 ), the backlight includes a backplane, a light source 3 arranged in the backplane, and a diffusion plate 4 arranged above the light source 3, and the thickness of a large-sized display device product is generally greater than 25mm due to the use of a direct-type backlight. It is not convenient for the thinning development of large-sized display devices. Contents of the invention [0003] The invention provides a backlight source and a display device, which are used to reduce the thickness of the backlight source, thereby facilitating the ...
