Abstract
The utility model discloses a kind of keyboard back light module, the light guide plate comprising backlight, one piece of folding substrate and be sandwiched in substrate, the substrate portion above described light guide plate is diffusion sheet, and the substrate portion below described light guide plate is reflector plate.Diffusion sheet and reflector plate are made of one by the utility model, make production process simplify, have the advantages that production efficiency is high, manufacturing cost is low.
Description
Technical field
The utility model relates to backlight module, specifically, relates to a kind of keyboard back light module.
Background technology
At present, the design of backlight module scheme used in keyboard is more, but is substantially made up of four parts, and be backlight, reflector plate, light guide plate and diffusion sheet from bottom to up, after being manufactured respectively by this different materials, then stack assembly gets up to form backlight module.Adopt and produce backlight module in this way, the operation of process is many and complicated, and need multidisciplinary, many manpowers to produce, affect formation efficiency, manufacturing cost is higher.
Summary of the invention
For the deficiencies in the prior art, the purpose of this utility model is to provide the keyboard back light module that a kind of production process is few, production efficiency is high, manufacturing cost is low.
For achieving the above object, the utility model is achieved through the following technical solutions: a kind of keyboard back light module, the light guide plate comprising backlight, one piece of folding substrate and be sandwiched in substrate, substrate portion above described light guide plate is diffusion sheet, and the substrate portion below described light guide plate is reflector plate.
Further illustrate, described diffusion sheet laminating light guide plate one side is printed with whitewash layer, and a hollowed printing away from light guide plate has blacking layer.
Further illustrate, described reflector plate laminating light guide plate one side is printed with reflective coating layer.
Compared with prior art, the utility model has following beneficial effect: diffusion sheet and reflector plate are bent by one piece of substrate and form, again light guide plate bag is clipped in the middle and carries out pressing, decrease diffusion sheet and reflector plate separately makes and assembles stacking operation, thus production efficiency is improved, manufacturing cost reduces.
Accompanying drawing explanation
Fig. 1 is for illustration of the schematic diagram of the utility model embodiment.
Fig. 2 is Fig. 1 top view.
Parts title and sequence number in figure: 6-blacking region, 1-expanding sheet 2-light guide plate 3-backlight 4-reflector plate 5-non-black coatings area
Detailed description of the invention
Below in conjunction with the drawings and specific embodiments, the utility model is described in further detail, but does not limit protection domain of the present utility model and range of application:
As shown in Figure 1, a kind of keyboard back light module, the light guide plate 2 comprising backlight 3, one piece of folding substrate and be sandwiched in substrate, the substrate portion above described light guide plate 2 is diffusion sheet 1, and the substrate portion below described light guide plate 2 is reflector plate 4.Diffusion sheet 1 and reflector plate 4 form by one piece of substrate is folding, then are clipped in the middle by light guide plate 2 bag and carry out pressing, decrease diffusion sheet 1 and reflector plate 4 separately makes and assembles stacking operation, thus production efficiency is improved, manufacturing cost reduction.Described substrate can be made up of PET, PC or PMMA material.
The keyboard back light module of the present embodiment, please refer to Fig. 1, Fig. 2, and the basis of previous technique scheme can be specifically, described diffusion sheet 1 fit light guide plate 2 one side be printed with whitewash layer, a hollowed printing away from light guide plate 2 has blacking layer.Described whitewash layer is made primarily of transparent resin mixed light diffusion material, for by the in addition evenly diffusion can allow light refraction angle of the light from light guide plate 2.Blacking layer is mainly opaque, is for avoiding backlight module light leak.
The keyboard back light module of the present embodiment, please refer to Fig. 1, the basis of previous technique scheme can be specifically, described reflector plate 4 fit light guide plate 2 one side be printed with reflective coating layer, such as make coating with highly reflective material TiO2, for the light that reflection light plate 2 penetrates.
The manufacturing process of the utility model keyboard back light module is: first with non-black coatings area 5 and the blacking region 6 of the large transparency carrier printing diffusion sheet opened, republish the white portion of diffusion sheet 1 and the reflective coating region of reflector plate 4, surrounding and the region print viscose glue that will bend, substrate is bent, the light guide plate 2 cut out is clipped in pressing in the middle of substrate, namely completes.Also after pressing completes, diffusion sheet 1 and reflector plate 4 connection substrate part can be cropped.
More than that the utility model keyboard back light module is set forth; the utility model is understood for helping; but embodiment of the present utility model is not restricted to the described embodiments; any do not deviate from the utility model principle under do change, modification, substitute, combination, simplify; all should be the substitute mode of equivalence, be included within protection domain of the present utility model.
