Description
Technical field
The utility model is related to field of backlights, more particularly to a kind of backlight and liquid crystal display module.
Background technology
As shown in figure 1, the narrow frame or Rimlessization of existing backlight are general by removing backlight left and right ends
Glue frame, and the mode for only retaining glue frame bar in upper and lower ends realizes do not have due to eliminating the optical film 3 ' on glue frame, light guide plate 2 '
There is a position limiting structure, and the width very little of the lightproof area of LCD 1 ', must be with leading which results in the edge of optical film 3 '
The justified margin of tabula rasa 2 ', otherwise, the position that light is easily not covered with optical film 3 ' from light guide plate 2 ' are spilt, this part light
Line so brightness can be than larger, thus generate the edge of backlight viewing area and gone out due to not by the processing of optical film 3 '
The problem of existing bright line, and the size of optical film 3 ' and light guide plate 2 ' due to making tolerance the problem of, both edges are nothing certainly
Method is perfectly aligned.
Utility model content
In order to solve above-mentioned the deficiencies in the prior art, the utility model provides a kind of backlight and liquid crystal display module.Should
Extend sideways out limiting platform of the glue frame bar of backlight upper and lower ends along the metal frame, for the optics on the light guide plate
The position limiting structure of film, the optical film is extended on the limiting platform, and the optical film completely covers the light guide plate
Exiting surface, the vision area bright line of narrow frame backlight can be solved the problems, such as.
Technical problem to be solved in the utility model is achieved by the following technical programs：
A kind of backlight, including metal frame, be arranged in the metal frame light guide plate, be arranged on the light guide plate and enter light
The first glue frame bar between face and the metal frame side, it is arranged on one side and the metal of the light guide plate away from incidence surface
The second glue frame bar between frame side, the light emitting source for being arranged on the light guide plate incidence surface, the first glue frame bar and the second glue
The two ends of frame bar are along the metal frame two the extend sideways out limiting platforms adjacent with the light emitting source；The light guide plate
An at least optical film is provided with exiting surface, the optical film is extended on the limiting platform.
Further, the top surface of the limiting platform is flushed with the exiting surface of the light guide plate.
Further, on the direction at the two ends adjacent with the light emitting source, the optical film and metal frame side
The distance between be less than or equal to the half of the distance between the light guide plate and the metal frame side.
Further, the width of the limiting platform is more than 0.2mm.
Further, the length of the limiting platform is more than 0.6mm.
