Description

Liquid crystal display module of leak protection light

Technical Field

The utility model relates to a liquid crystal display technical field especially relates to a liquid crystal display module assembly of leak protection light.

Background

For the liquid crystal display module with the narrow frame, the position of the hole position such as the IR hole is closer to the liquid crystal display module, and the liquid crystal display module leaks light between the backlight rubber frame and the shading rubber due to the structure, so that the light leakage at the position of the IR hole is seen from the front side of the whole machine after the whole machine is assembled, and the attractiveness of the whole machine is influenced. There are two common solutions to solve this problem, one is to set up a light-shielding glue 300 on the liquid crystal display module 100 corresponding to the IR hole 200, and the other is to stick a light-shielding glue 300 on the liquid crystal display module as shown in fig. 1 to fig. 3.

Accordingly, the prior art is deficient and needs improvement.

SUMMERY OF THE UTILITY MODEL

The utility model aims at overcoming the not enough of prior art, provide a LCD module of leak protection light.

The technical scheme of the utility model as follows: the utility model provides a liquid crystal display module of leak protection light, include: cover plate glass, LCD module and backlight unit, cover plate glass, LCD module and backlight unit are from last to stacking up the setting down, cover plate glass is equipped with the IR hole, backlight unit is including locating the shading at backlight unit top is glued, corresponds IR hole position department the shading is glued and is outwards extended and form an extension, the extension is buckled attached backlight unit's side.

Further, the distance from the two end edges of the extension part to the two end edges of the corresponding IR hole is 2 mm to 3 mm.

Further, the extension is rectangular.

Further, backlight unit still includes glued chase, reflectance coating, light guide plate, diffusion barrier, lower membrane, last membrane and the LED subassembly that adds lustre to, the extension is attached in glued chase's lateral wall.

Or the extension part is bent and attached to the side surface and the bottom of the backlight module.

Further, backlight unit still includes glued chase, reflectance coating, light guide plate, diffusion barrier, lower membrane, goes up membrane and the LED subassembly that adds lustre to, the extension is attached in glued chase's lateral wall and bottom.

According to the above technical scheme, the utility model discloses on being applied to the liquid crystal display module of narrow frame, glue the extension through the shading that corresponds the backlight unit department of position department with the IR pore and attach in the backlight unit side, can prevent that IR pore department from appearing the problem of light leak, simultaneously for prior art, need not to purchase a shading glue more and attach the process together, be favorable to reduce cost and lifting efficiency.

Detailed Description

The present invention will be described in detail below with reference to the accompanying drawings and specific embodiments.

Referring to fig. 4 to 7, in the present embodiment, the present invention provides a liquid crystal display module with light leakage prevention, including: cover plate glass 1, LCD module (not mark) and backlight unit 2, cover plate glass 1, LCD module and backlight unit 2 are from last to stacking up the setting down, cover plate glass 1 is equipped with IR hole 11, backlight unit 2 is including locating the shading at 2 tops of backlight unit glues 21, corresponds IR hole 11 position department shading is glued 21 and is outwards extended and form an extension, the extension is the rectangle, the extension is buckled attached in backlight unit 2's side, specifically, backlight unit 2 still includes gluey iron frame 22, reflectance coating, light guide plate, diffusion barrier, the membrane that adds lustre to down, goes up the membrane that adds lustre to and LED subassembly, the extension attached in gluey iron frame 22's lateral wall. The distance L from the edges of the two ends of the extension part to the corresponding edges of the two ends of the IR hole 11 is 2 mm to 3 mm, so that the light leakage problem can be effectively prevented.

This scheme can also have other some embodiments, for example in some embodiments of this scheme, compare with above-mentioned embodiment, liquid crystal display module structure difference lies in that the extension that the shading glued is buckled and is attached on outer wall and bottom on the gluey chase, can obtain better effect of pasting, and all the other structures are the same, do not describe herein repeatedly.

To sum up, this scheme is applied to the liquid crystal display module assembly of narrow frame, glues the extension through the shading with the backlight unit department that IR hole corresponds position department and attaches in the backlight unit side, can prevent that IR hole department from appearing the problem of light leak, simultaneously for prior art, need not to purchase a shading glue more and attach the process together more, is favorable to reduce cost and raises the efficiency.

The above description is only exemplary of the present invention and should not be construed as limiting the present invention, and any modifications, equivalents and improvements made within the spirit and principles of the present invention are intended to be included within the scope of the present invention.
