Abstract
The utility model relates to LCD module technical field, refers in particular to a kind of light guide plate; The utility model comprises main body, and the bottom of main body has multiple hemispherical site of evenly distributed smooth bumps; When the utility model uses after mounting, the light of light source is derived from light guide plate, produces multiple reflections, refraction via the hemispherical site of smooth bumps, and can ensure to export uniform light, overall brightness promotes 20%, the quality of improving product.
Description
Technical field
The utility model relates to LCD module technical field, refers in particular to a kind of light guide plate.
Background technology
Existing LCD module, the light guide plate that it uses is all generally block structure, the front end of light guide plate coordinates with light source, light conduction through light guide plate front end, then is gone out by light guide plate by light, and overall light guide plate is bright state, because light source is pointolite substantially, so light conducts through light guide plate, there will be light and export uneven situation, what light guide plate presented has dark space and clear zone, this will affect the quality of product, causes quality problem.
Therefore, based on the defect of above-mentioned existing light guide plate, need to improve existing light guide plate.
Utility model content
The purpose of this utility model is to provide a kind of light guide plate for the deficiencies in the prior art, and this kind of light guide plate solves existing for existing light guide plate: light exports inequality, affects the defects such as product quality.
For achieving the above object, the utility model is achieved through the following technical solutions:
A kind of light guide plate, comprise main body, the bottom of main body has multiple hemispherical site of evenly distributed smooth bumps.
The hemispherical site of smooth bumps has the smooth sphere to main body evagination.
The front end of main body is formed with multiple evenly distributed sawtooth.
The cross section of sawtooth is triangular in shape.
The front portion of main body has protruding dip plane.
Sawtooth is positioned at dip plane foremost.
The beneficial effects of the utility model are: form multiple hemispherical site of evenly distributed smooth bumps in the bottom of main body, when light is derived from light guide plate, multiple reflections, refraction is produced via the hemispherical site of smooth bumps, can ensure to export uniform light, overall brightness is consistent, output brightness can promote 20%, the quality of improving product.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
Fig. 2 is another angle schematic diagram of Fig. 1.
Fig. 3 is schematic side view of the present utility model.
Embodiment
Below in conjunction with accompanying drawing, the utility model is further described.
See Fig. 1, Fig. 2, a kind of light guide plate of the utility model comprises: main body 1, the light of light source exports through the bottom of main body 1, the bottom of main body 1 has the hemispherical site 4 of multiple evenly distributed smooth bumps, the hemispherical site 4 of smooth bumps has the smooth sphere to main body 1 evagination, the effect of the hemispherical site 4 of smooth bumps is the light guiding light source to send, when light is exported from light guide plate, light is through the hemispherical site 4 of smooth bumps, by the multi-angle remission of the hemispherical site 4 of smooth bumps, light is exported more even, the light effect that light guide plate entirety presents is better.
Further, the front end of main body 1 is formed with sawtooth 2, and the effect of sawtooth 2 is the light guiding light source to send, make light when sawtooth 2, multidirectional reflection, refraction can be produced, make light more even, also very even when light enters light guide plate, the light effect that light guide plate entirety presents is better; Wherein, sawtooth 2 has multiple, along the center line symmetric offset spread of main body 1.
More specifically, the cross section of sawtooth 2 is triangular in shape.
See Fig. 3, the front portion of main body 1 has protruding dip plane 3, and this dip plane 3 makes the front portion of main body 1 higher relative to other parts, and the height of sawtooth 2 is increased, and the light of light source more conveniently can enter light guide plate, increases the result of use of product.
Light guide plate of the present utility model is by mechanical impact processing mold, and make mould to be formed evenly distributed pit, the light guide plate mesh point after injection mo(u)lding is even, fine and closely woven, surperficial unusual light, and the light guide plate that overall brightness can be more traditional promotes more than 20%.
The utility model structure is simple, easy to assembly, and light guide effect is good.
Certainly, the embodiment of the above, just preferred embodiments of the present utility model, and unrestricted the utility model practical range, therefore all equivalences done according to structure, feature and the principle described in the utility model claim change or modify, and all should be included in the utility model claim.
Claims (5)
