Embodiment Construction

[0019] The technical solutions of the present invention will be further described below in conjunction with the accompanying drawings and embodiments. The specific embodiments described here are only used to explain the present invention, but not to limit the present invention.

[0020] An embodiment of the present invention provides a backlight module, such as Figure 1-3 As shown, it includes: a housing 1 , a light guide column 2 and a light emitting component 3 .

[0021] see Figure 1-3 A plurality of light guide columns 2 are evenly spaced inside the housing 1. The light guide columns 2 are hollow semi-cylindrical bodies, and the openings at both ends of the cavity are light inlets, and the outer walls of the light guide columns 2 are light output surfaces. The housing 1 The two ends of the hollow cavity of the light guide column 2 are provided with a light-emitting component 3, and the light emitted by the light-emitting component 3 is transmitted from one end of the h...

Abstract

The invention discloses a backlight module which comprises a shell, light guide columns and light emitting parts. The light guide columns are evenly arranged in the shell at intervals and are hollow semi-cylinders. Openings in the two ends of a hollow cavity of each light guide column are light inlets, the outer walls of the light guide columns are light emitting faces, and the light emitting parts are arranged on the two ends of the hollow cavities of the light guide columns in the shell. Light emitted by the light emitting parts is transmitted to the other end from one end of the hollow cavity of each light guide column and then evenly scattered on a liquid crystal display screen by means of the semi-cylindrical light emitting faces, point light sources are converted into a plane light source, the number of LEDs in use is reduced, and development cost of the backlight module is effectively reduced.

Description

technical field [0001] The invention relates to the field of display technology, in particular to a backlight module. Background technique [0002] In recent years, display technology has developed rapidly, and liquid crystal displays have become the main display devices. The backlight module is one of the key components of the liquid crystal display, which is used to supply sufficient brightness and uniformly distributed light source so that it can display images normally. The luminous effect of the backlight module will directly affect the visual effect of the liquid crystal display. At present, according to the position of the light source distribution, the backlight module is mainly divided into two types: direct type and side type. Among them, in the direct-type backlight module, the light emitted by the LED light source is directly dispersed upward through the diffusion plate, and then emitted in the direction of the liquid crystal screen. The thickness of the direct...
