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 invention discloses a back frame for mounting a backlight, the backlight and a display device. The back frame comprises a frame body and a light source base; the frame body comprises a containing space for bearing a light guide plate; the light source base is detachably connected with the frame body, and a light source is placed on the light source base. The backlight comprises the back frame. The display device comprises the backlight. Since the light source base is detachably connected with the frame body, the light source placed on the light source base can be dismounted from the back frame, consequently, the light source can be replaced under the premise that a display panel is not dismounted, the internal environment of the backlight cannot be destroyed, the internal material of the backlight cannot be injured or damaged, as a result, the replacement cost is reduced, and resource waste is prevented.

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)....
