Description
Technical field
The present invention relates to a kind of plate lighting ultra-thin light guide board, belong to display technology field.
Background technology
Light guide plate printing ink is the important materials of the backlight module of light guide plate, is printed to ink instead by screen printing technique
Luminous point, area source is changed into by original spot light, is reached the consistent effect of the luminous uniform, brightness of whole light guide plate, extensively should
In terms of television display, mobile telephone display, notebook are shown, with high technology content and application value.It is existing
Have light guide plate printing ink generally use UV and IR in slow curing curable ink, slow drying speed, briliancy is low, uniformity of luminance is poor, attached
Put forth effort small, increase production manufacturing process time, low production efficiency, it is impossible to the requirement for meet energy-conservation, efficiently producing, and dry
The roasting plant used when dry is the long IR stove of 8-12m, near-infrared Segmented heating, and temperature hardly possible is controlled and difference is big, when equipment hair
When raw abnormal, then the product in stove net is all scrapped, and wastes resource, increases the production cost of enterprise, and the equipment is held
It is also easy to produce baking uneven, causes black and white shadow phenomenon, printing effect is poor.Existing illumination light guide plate is mainly printed using ink
Mode make, it is low to there is light utilization efficiency, the shortcomings of pollution environment.
The content of the invention
The technical problem to be solved in the present invention is：There is provided a kind of lifting of emitting brightness uniformity, making for diffuser plate is reduced
Plate lighting ultra-thin light guide board, solves the illumination that the mode printed using ink made and light profit is there is with light guide plate
With rate it is low, pollution environment the problem of.
In order to solve the above-mentioned technical problem, the technical scheme is that there is provided a kind of ultra-thin leaded light of plate lighting
Plate, it is characterised in that including light guide plate, the exiting surface of light guide plate is provided with the prism knot that can compress emergent light to vertical direction
Structure, the bottom surface of light guide plate is provided with the lattice point structure made using thermoforming process, and lattice point structure is made up of multiple light directing sites.
Preferably, the periphery of described light directing site is formed with an annular groove, and there is a circular projection centre.
Preferably, the diameter of each described light directing site is between 50~100um.
Preferably, light directing site of the bottom surface of described light guide plate provided with random arrangement or array arrangement.
Preferably, the dutycycle of multiple described light directing sites is more than the base area of 50% light guide plate.
The material of the light guide plate of the present invention can reduce 1mm than present light guide plate, and emitting brightness uniformity is lifted,
Reduce the use of diffuser plate.Suitable for the LED flat plate illuminator with side entering type, the backlight module using this kind of light guide plate has light
Line use ratio is high, the beneficial effect of uniform in light emission, it is to avoid the pollution environment produced using ink.

Embodiment
To become apparent the present invention, hereby with preferred embodiment, and accompanying drawing is coordinated to be described in detail below.
The present invention is a kind of plate lighting ultra-thin light guide board, it is adaptable to the LED flat plate illuminator with side entering type, is used
The backlight module of this kind of light guide plate has light utilization height, the beneficial effect of uniform in light emission.As Figure 1-Figure 4, it includes leading
Tabula rasa 2, the exiting surface of light guide plate 2 is provided with prism structure 1, can compress emergent light to vertical direction；The bottom surface of light guide plate 2 is set
There is lattice point structure, lattice point structure is made using thermoforming process.Lattice point structure is due to multiple random arrangements or array arrangement
Light directing site 3 is constituted, and the periphery of light directing site 3 is formed with an annular groove, and there are a circular projection, each leaded light net in centre
The diameter of point 3 is between 50~100um.The dutycycle of multiple light directing sites 3 is more than the base area of 50% light guide plate 2, tool
There is atomized surface effect, it is possible to reduce the use of diffusion barrier.The light directing site 3 of the present invention is lenticule site.The plurality of light directing site 3
Closeer from incidence surface (i.e. the surrounding side of light guide plate 2) more remote distribution, the density of light directing site 3 is bigger.
Lattice point structure is made using thermoforming process, i.e., processed based on volume to volume hot-rolling compression polymer film surface micro-structural
Method, its process comprises the following steps：
(1) blowing
Sheet material to be imprinted is put into feeding belt, and film surface electrostatic is removed by electrostatic eliminating brush, by feeding belt by plate
Material is transported to press roll；
(2) preheat
Sheet material to be imprinted is preheated by heat-transfer equipment, and the temperature of sheet material to be imprinted is controlled at it by Temperature-controlled appliance
Below glass transformation temperature；
(3) hot-rolling pressure
Local heating is carried out to roller by localized heating device, pressure roller coordinates roller by the fine structure pattern in roller
It is impressed on sheet material to be imprinted；
(4) cool down
Cool down tuyere air-cooled to sheet material progress, and after sheet material leaves pressure roller, the sheet material after hot pressing is quickly cooled to glass
Below glass transition temperature, resilience is reduced, forming accuracy is improved；
(5) rewinding
The sheet material that impressing has surface fine structure pattern is passed through into receiving mechanism rewinding.
