Abstract
The utility model discloses a kind of light guide plates.The technical solution of the utility model is：Including light conducting plate body,It is lentiform connector that the surrounding of the light conducting plate body, which is provided with shape,,The side of the light guide is provided with the LED light source that light-emitting surface height is 0.45mm,The thickness of the light conducting plate body is less than 0.4mm,The utility model has the following advantages compared with the prior art,The embodiment of the utility model its can effectively reduce the light leakage phenomena of backlight module,Due to the minimum 0.45mm of light-emitting surface height of the LED light source of the prior art,Therefore,If the thickness of light guide plate is smaller than light-emitting surface height,It thus will appear more apparent light leakage phenomena,It is lentiform connector by being provided with shape in the surrounding of light conducting plate body,Light enters light guide plate after will being assembled by connector in this way,Effectively prevent the generation of light leakage phenomena,Wherein the thickness of light conducting plate body is less than 0.4mm,Setting connector in this way is just significant.
Description
Technical field
The utility model is related to back light model setting technology field, more particularly to a kind of light guide plate.
Background technology
Existing backlight module the phenomenon that there are light leakages, when especially light guide plate is very thin, the especially hair of LED light source
Light leakage phenomena is just than more serious when smooth surface height is compared with hour, therefore, the ratio in the prior art usually designing the shape of light guide plate
More complex to improve into light rate, which adds design cost and processing costs.
Utility model content
In view of the deficienciess of the prior art, the main purpose of the utility model is to provide one kind capable of effectively reducing the back of the body
The light guide plate of the light leakage phenomena of optical mode group.
To achieve the above object, the utility model provides following technical solution：A kind of light guide plate, including light guide plate sheet
Body, it is lentiform connector that the surrounding of the light conducting plate body, which is provided with shape, and the side of the light guide is provided with light extraction
Face height is the LED light source of 0.45mm, and the thickness of the light conducting plate body is less than 0.4mm.
Preferably, the light conducting plate body and connector are integrally formed setting.
Preferably, the height of the connector is more than the height of LED light-emitting surfaces.
The utility model has the following advantages compared with the prior art, and a kind of light guide plate of the utility model can have
Effect reduces the light leakage phenomena of backlight module, due to the light-emitting surface minimum 0.45mm of height of the LED light source of the prior art,
If the thickness of light guide plate is smaller than light-emitting surface height, it thus will appear more apparent light leakage phenomena, the scheme of the application is logical
The surrounding crossed in light conducting plate body is provided with shape for lentiform connector, after such light will be assembled by connector
Into light guide plate, the generation of light leakage phenomena is effectively prevented, the wherein thickness of light conducting plate body is less than 0.4mm, and setting in this way connects
Junctor is just significant.
Description of the drawings
Fig. 1 is a kind of structural schematic diagram of light guide plate of the utility model.
In figure：1, light conducting plate body；2, light-emitting surface；3, connector.
Specific implementation mode
The utility model is described in further detail below in conjunction with the accompanying drawings.
As shown in Figure 1, a kind of light guide plate, including light conducting plate body 1, the surrounding of the light conducting plate body 1 are provided with shape
For lentiform connector 3, the side of the light guide is provided with the LED light source that 2 height of light-emitting surface is 0.45mm, described to lead
The thickness of tabula rasa ontology 1 is less than 0.4mm.
A kind of light guide plate of the utility model can effectively reduce the light leakage phenomena of backlight module, due to the prior art
LED light source the minimum 0.45mm of height of light-emitting surface 2, therefore, if the thickness of light guide plate is smaller than 2 height of light-emitting surface, in this way
It just will appear more apparent light leakage phenomena, the scheme of the application is by being provided with shape in the surrounding of light conducting plate body 1
Specular connector 3, such light enter light guide plate after will being assembled by connector 3, effectively prevent light leakage phenomena
Occur, wherein the thickness of light conducting plate body 1 is less than 0.4mm, and it is just significant that connector 3 is arranged in this way.
Preferably, the light conducting plate body 1 and connector 3 are integrally formed setting.
The purpose being arranged in this way is to improve machining accuracy and reduce production cost, and light conducting plate body 1 is used with connector 3
Dedicated mold integrated molding is made, also than stronger in the structural strength of itself.
Preferably, the height of the connector 3 is more than the height of LED light-emitting surfaces 2.It can ensure light almost all in this way
Light guide is entered by connector 3, further reduced the generation of light leakage phenomena.
The above is only the preferred embodiment of the utility model, and the scope of protection of the utility model is not limited merely to
Above-described embodiment, technical solution belonging to the idea of the present invention belong to the scope of protection of the utility model.It should refer to
Go out, for those skilled in the art, it is without departing from the principle of the utility model it is several improvement and
Retouching, these improvements and modifications also should be regarded as the scope of protection of the utility model.
