Problems solved by technology

Since the existence of the gap will cause problems such as dust ingress, which will affect the use of the entire product, and the thickness of the gap is very thin, only about 0.4mm, if you want to make some bosses on the plastic front frame to make up for the gap, Such a small size, plastic mold forming is difficult

Abstract

The invention provides a sidelight type backlight module which comprises a back plate, a light guide plate, at least one LED (light-emitting diode) bead and at least one LED reflector. The back plate comprises a bottom plate, a first side plate and a second side plate, wherein the first side plate is connected with the bottom plate, and the second side plate is opposite to the bottom plate and connected with the side plate. The light guide plate is arranged in the back plate, the at least one LED bead is arranged on the side edge of the light guide plate, and the at least one LED reflector is arranged on the upper side of the light guide plate and connected with the second side plate. Each LED reflector comprises an adhesive-providing area and a non-adhesive area, and edges of two ends of each adhesive-providing area are longitudinally bent inwards along the corresponding LED reflector to form flanging portions. After the whole module is covered by a front frame, components of the modules are closer in combination, the ash accumulation problem can be reduced, and the product service life is guaranteed to a great extent. Furthermore, the initial position for adhesion of each LED reflector can be controlled through the flanging portions of the corresponding LED reflector to meet the requirements on adhesion positions.

Description

technical field [0001] The invention relates to the field of LED lighting, in particular to an edge-light backlight module. Background technique [0002] A liquid crystal display (LCD, Liquid Crystal Display) has many advantages such as a thin body, power saving, and no radiation, and has been widely used. Most of the liquid crystal display devices currently on the market are backlight liquid crystal display devices, which include a liquid crystal panel and a backlight module. The backlight module is one of the key components of the liquid crystal display. The backlight module is divided into side-type backlight modules and direct-type backlight modules according to the incident position of the light source. Since the edge-lit backlight module sets the light source generator on the side of the display panel, it can reduce the size and manufacturing cost of the liquid crystal display, so it is widely used in small electrical products, such as digital cameras and digital pers...
