Problems solved by technology

[0005] The technical problem to be solved by the present invention is that the light source on the existing display device is packaged together with the light guide plate and the optical film in the plastic frame under the display panel, and the replacement of the light source requires dismantling the display panel and the backlight unit, which is easy to install. If the display panel is damaged, it is easier to cause damage to the optical film and light guide plate in the backlight unit, thereby destroying the original display effect of the display device or wasting resources

Abstract

The embodiments of the present invention provide a back frame for installing back light source, a back light source and a display device. The back frame comprises a frame body having an accommodation space for holding a light guide plate; a light source seat detachably connected to said frame body for placing a light source. In the embodiments of the present invention, the light source seat and the frame body are connected detachably so that the light source disposed on the light source seat can be detached from the back frame, which realizes that the light source can be replaced without the need of detaching the display panel, the environment inside the back light source is not destroyed, the material inside the back light source is not harmed or destroyed, thus the replacement cost is reduced and the waste of resources is avoided.

Description

technical field [0001] The invention relates to the display field, in particular to a back frame for installing a backlight source, a backlight source and a display device. Background technique [0002] Liquid Crystal Display (LCD) does not emit light by itself. In order to clearly see the content displayed on the LCD display, it needs the support of a backlight source to obtain color rendering. The side-type backlight module is generally composed of necessary optical components such as a light source, a film, a reflector, a light guide plate, and a back plate. [0003] The backlight unit is an important part of the liquid crystal display device, including the backlight and the components for installing the backlight. Its structure, assembly, cost, and weight are all important technical indicators. The existing backlight has always played an important role in the entire backlight unit as the backplane and plastic frame that carry the backlight and the panel (display panel)....
