Problems solved by technology

However, in the traditional backlight module manufacturing process, stamping is usually used to manufacture the backplane and the strengthening structure on it; and for the stamping process of large-sized metal plate parts, compared with the stamping of small-sized metal plate parts, it has more advantages. Higher difficulty and higher cost

Embodiment Construction

[0030] see Figure 1A and Figure 1B , respectively are an assembly schematic diagram and an exploded schematic diagram of the backlight module of an edge-lit liquid crystal display according to the first preferred embodiment of the present invention. The backlight module 1 of an edge-lit liquid crystal display includes a light source 11 , an edge-lit optical film set 12 , a frame 13 and a back plate 14 . For example, the edge-lit optical film set 12 can be composed of a light guide plate 121 and an optical film 122 . The frame 13 is combined with the backboard 14 . The material of the back plate 14 can be metal (such as aluminum) or plastic.

[0031] In this embodiment, the frame 13 is mainly assembled by a plurality of side bars 131 and a plurality of connecting parts 132 . The side strips 131 are arranged around the edge-lit optical film set 12, and the light source 11 is arranged on at least one of the side strips 131. In this preferred embodiment, the light source 11 i...

Abstract

The invention provides a liquid crystal display and a side light type liquid crystal display backlight module. The side light type liquid crystal display backlight module comprises a light source, a side light type optical membrane set, a frame and a back plate, wherein the frame is combined with the back plate and comprises a plurality of side strips and a plurality of combining members; the light source is arranged on at least one of the side strips; and the side strips are integrally connected with the combining members to form a first accommodating space to accommodate the side light type optical membrane set.

Description

technical field [0001] The invention relates to a liquid crystal display backlight module and a liquid crystal display, in particular to a side light liquid crystal display backlight module and a liquid crystal display. Background technique [0002] The backlight module is a key module of the liquid crystal display, which provides sufficient and uniform light so that the liquid crystal display can display images normally. The backlight module mainly includes optical films such as a light source and a reflective film, and can be roughly divided into two types: "direct type backlight module" and "side light type backlight module" according to the arrangement of the light source. [0003] Traditional direct-lit backlight modules are mostly used in large-sized LCD TVs or LCD monitors, because the light source is arranged on the back of the LCD monitor. The light is directly incident on the display panel, or the light is reflected to the front of the display panel through the re...
