Abstract

The invention relates to a backlight, a production method thereof, a backlight bottom frame and a production method thereof in the technical field of display. The backlight comprises an optical film, a light guide plate, a light source and the bottom frame, wherein the optical film is fixed on the top surface of the light guide plate, the light source is fixed on the side or bottom of the light guide plate, the bottom surface of the light guide plate is fixed on the bottom frame, the bottom frame comprises a reflective layer and a metal layer, and the reflective layer is in contact with the light guide plate. The production method of the backlight includes the following steps: composite materials, which are a reflective material and a metal material, are provided, and the reflective material and the metal material are stacked together; the composite materials are formed into the bottom frame, which comprises the reflective layer and the metal layer; the light guide plate is provided, and the bottom surface of the light guide plate is fixed on the reflective layer; the optical film is provided, and is placed on the top surface of the light guide plate; and the light source is provided, and is arranged on the side or bottom of the light guide plate. The frame of the backlight can be narrow, the production steps are simplified, and the production cost is reduced.

Description

technical field [0001] The invention relates to the field of display technology, in particular to a backlight source and a manufacturing method thereof, a backlight source bottom frame and a manufacturing method thereof. Background technique [0002] With the development of liquid crystal displays, liquid crystal displays are becoming more and more popular among consumers and widely used in various fields due to their advantages of thin thickness, small volume and small space occupation. Among them, in order to further save space, liquid crystal displays are increasingly required to have narrower borders. The liquid crystal display mainly includes: a backlight source and a liquid crystal display panel located on the backlight source. One of the determining factors of the frame width of the liquid crystal display is the distance between the edge of the liquid crystal display panel and the edge of the backlight source, that is, the frame width of the backlight source. [000...
