Problems solved by technology

Therefore, when the light hits the glue inlet point 134 of the light guide plate, because there is no glue frame here to block the light, part of the light is lost from the recess 134, resulting in the inability to use the light effectively, and when the liquid crystal display is in operation, this shadows everywhere
This shadow will cause uneven brightness and poor picture quality of the LCD display

Abstract

The invention discloses a negative phototropic module structure. It comprises a shaped body glue frame and light leading plate, a light leading plate glue inlet point on one side of the glue frame, an anti-dazzle film, and a reflecting plate. The negative phototropic module uses the extension of the anti-dazzle film or the reflecting plate to cover the light leading plate glue inlet point so that the light can not be leaked by the light leading plate glue inlet point to generate the dark field.

Description

technical field [0001] The invention relates to a backlight module, in particular to a backlight module which solves the problem of light leakage from an integrally formed plastic frame and a light guide plate. Background technique [0002] With the vigorous development of the optoelectronic industry, liquid crystal display modules (liquid crystal display; LCD) have been widely used in various notebook computers (notebooks), personal digital assistants (personal digital assistants; PDAs) and mobile phones (cell phones), etc. in the electronic device. However, the liquid crystal display is a non-self-illuminating flat panel display, which needs to be illuminated by an external backlight or side light. Therefore, a backlight module is always used as a light source in a liquid crystal display, and the high-brightness and high-uniformity illumination of the backlight module enables the liquid crystal display to efficiently display high-quality pictures. [0003] refer to Figu...
