On the 4th lateral surface of the light guide plate, the optical film material component includes successively being attached to the light guide plate upper surface
Diffusion sheet, lower brightening piece and upper brightening piece, the glue frame middle part form a step, and the optical film material component is crushed on the glue
Under the step of frame, the optical film material component and light guide plate are wrapped between the glue frame and reflector plate, the light guide plate
Be 2.1 millimeters, the diffusion sheet, lower brightening piece and upper brightening piece with a thickness of 0.2 millimeter.
Further, the distance of surface to corresponding LCD surface of adding lustre on described is greater than 0.05 millimeter and less than 3 millimeters.
Further, the distance of the upper brightening piece surface to corresponding LCD surface is 0.94 millimeter.
Further, the lower iron frame is totally enclosed type.
Further, the glue frame step convexes to form " T " font structure.
Further, the LED component further includes the connecting wire connecting with the LED light bar and covers in the connection
Protection pipe sleeve on conducting wire, the outgoing line position of the connecting wire are located on the short side of the backlight module.
Further, described connecting wire one end is connect with the LED light bar, the other end directly with use the backlight mould
The mainboard connection of the equipment of group.
Using the above scheme, the utility model provides a kind of display module of high reliability for industrial control equipment, has
High reliablity and advantage at low cost.
Detailed description of the invention
Fig. 1 is the structural schematic diagram of the utility model.
Fig. 2 is the enlarged drawing in Fig. 1 at A.
Fig. 3 is the side view of the utility model.
Fig. 4 is connecting wire schematic diagram.
Specific embodiment
Below in conjunction with the drawings and specific embodiments, the utility model is described in detail.
The utility model provides a kind of display module of high reliability referring to FIG. 1 to FIG. 4, and the display module is used for
Industrial control equipment, comprising: FOG8 and backlight module, the FOG8 include polaroid and LCD, and the backlight module includes: lower iron frame
1, light guide plate 4, reflector plate 3, LED component, optical film material component and glue frame 2,2 color of glue frame are black, the LED component
Including LED light bar and several LED being welded in the LED light bar, three sides of the reflector plate 3 are pre- cut edge, described anti-
It penetrates piece and is attached at the bottom surface of light guide plate and three lateral surfaces, can prevent 2 extinction of the glue frame of black from causing the backlight
Mould group brightness reduce, the LED light bar be set to the 4th lateral surface of the light guide plate 4 on, the optical film material component include according to
Secondary diffusion sheet 5, lower brightening piece 6 and the upper brightening piece 7 for being attached to 4 upper surface of light guide plate forms one in the middle part of the glue frame 2
Rank, 2 step of glue frame convex to form " T " font structure, and the optical film material component is crushed under the step of the glue frame 2,
The optical film material component and light guide plate 4 are wrapped between the glue frame 2 and reflector plate 3, then group loads iron frame so as to save
The common shading glue of backlight module, advantageously reduces cost, and glue frame is designed as black, due to black can absorb optical film material with
The light of glue frame contact edge, so also can solve bright border problem when facing；The light guide plate 4 is with a thickness of 2.1 millimeters, the diffusion
The thickness of piece 5, lower brightening piece 6 and upper brightening piece 7 is 0.2 millimeter, due to the light guide plate 4 and optical film material component thickness compared with
Thickness is conducive to save the cost and promotes reliability to the tolerance performance of temperature also with raising.The LED can also select ratio
