Backlight module structure

Abstract

The invention discloses a backlight module structure comprising a backboard, wherein the backboard comprises a body, a side wall is respectively arranged at each of the four edge portions of the body,the body and the four side walls form an accommodating cavity for accommodating a light guide plate, one of the four side walls is formed as a light incident side wall, the other three side walls areformed as light shielding side walls, wherein the light incident side wall corresponds to a light incident side of the light guide plate, silica gel strips are arranged on the inner sides of the three light shielding side walls, and a plastic frame clamped on the light guide plate is not arranged in the backboard. In the backlight module structure disclosed by the invention, the conventionally used plastic frame is eliminated, the silica gel strips are directly arranged on the three light shielding side walls, and the existing plastic frame is replaced with the silica gel strips, thereby reducing the product cost, improving the assembly efficiency, and reducing the size matching influence of the plastic frame and backboard under the premise of ensuring normal functions of the backlight module structure.

Description

technical field [0001] The invention relates to a backlight module structure. Background technique [0002] After decades of development, the shape of the backlight module has been constantly evolving, the thickness is getting thinner and the frame is getting narrower and narrower. However, the overall frame in the LCD liquid crystal display is still composed of several major components such as the back plate, plastic frame, light guide plate, reflector, light bar, and diaphragm. The plastic frame material that supports the LCD panel has been continuously optimized and improved on the raw material particles, injection process, and structure. It has always been one of the core components of the backlight module and cannot be replaced. The plastic frame needs to be formed by injection molding. Taking the mainstream size of notebook computers (11.6-15.6 inches) as an example, a set of plastic frame molds needs more than 200,000 RMB, which is expensive; Such key control items ...

Problems solved by technology

The plastic frame material that supports the LCD panel has been continuously optimized and improved on the raw material particles, injection process and structure. It has always been one of the core components of the backlight module and cannot be replaced.

The plastic frame needs to be formed by injection molding. Taking the mainstream size of notebook computers (11.6-15.6 inches) as an example, a set of plastic frame molds needs more than 200,000 RMB, which is expensive; Such key control items are prone to defects, which affect the efficiency and yield of backlight assembly; the size of the plastic frame buckle is difficult to control, and it is easy to have problems such as difficult jamming and jumping out when it is engaged with the backplane. It is necessary to continuously modify the mold for adjustment, which also affects production. Efficiency and Project Schedule
