Abstract
The utility model discloses a kind of gauge without light source backlight liquid crystal mould groups, including light guide plate, the light guide plate is connected in backlight glue frame, the glutinous viscous double faced adhesive tape of the horizontal edge of light guide plate is for gluing mucus crystalline substance LED, the notch side plane of the backlight glue frame is equipped with light trough, several LED light are fixedly mounted in light trough, several LED light are linearly electrically connected flexible circuit board；Using the backlight packaging technology structure of the utility model, the light for reducing cost and mould group shows the uniformity, and the service life extends one year cyclic vibration；The light of different colours, especially solves the technical issues of LED light cannot issue white light under the capable of emitting spectrum different from ultraviolet to infrared of LED light；The difficulty of processing and the difficult virtue of assembling of backlight are also reduced, is greatly improved production capacity and efficiency, while also avoiding LED light and showing dark yellow phenomenon.
Description
Technical field
The utility model relates to electronic product liquid crystal display technical fields, more particularly to a kind of gauge without light source backlight liquid crystal
Mould group.
Background technique
Backlight is to provide the light source of LCD panel, is mainly made of light source, light guide plate, optical film piece, plastic plate etc..
Liquid crystal display is passive light-emitting component, and display screen itself does not shine, but is illuminated by back light system below
, backlight and liquid crystal display are combined and constitute LCD MODULE.
Due to CCFL(cold-cathode fluorescence lamp on traditional LCD display device) certain inadequate natural endowments of backlight technology and product,
Such as colour gamut is narrow, energy utilization rate is low, and power consumption is higher and the service life is short and small etc..Thus in field, technical staff exists always
Its solution is found, and in this process, on the backlight combination LCD integrated LED lamp of no LED light, liquid is solved with this
The light of brilliant mould group shows the uniformity and the service life extends.
Utility model content
The purpose of this utility model is to provide a kind of gauge without light source backlight liquid crystal mould group for existing issue.
The utility model is achieved through the following technical solutions: a kind of gauge without light source backlight liquid crystal mould group, including light guide plate,
The light guide plate is connected in backlight glue frame, and the glutinous viscous double faced adhesive tape of the horizontal edge of light guide plate is for gluing mucus crystalline substance LED, the back
The notch side plane of optical cement frame is equipped with light trough, several LED light is fixedly mounted in light trough, several LED light are linearly electrically connected flexibility
Wiring board.
As further improvement of these options, the LED light is electrically connected flexible wires by the way of electric welding
Turning circuit on the plate of road.
As further improvement of these options, the flexible circuit board is equipped with for assembling LCD liquid crystal display
Reflexed region.
As further improvement of these options, several LED light are electrically connected at using parallel way
Power supply.
As further improvement of these options, double faced adhesive tape carries out opposite face shading using black double-sided adhesive tape.
The utility model has the advantage that the backlight packaging technology structure using the utility model compared with prior art,
The light for reducing cost and mould group shows the uniformity, and the service life extends one year cyclic vibration；Under the capable of emitting spectrum different from ultraviolet to infrared of LED light
The light of different colours especially solves the technical issues of LED light cannot issue white light；Also reduce the difficulty of processing of backlight
And the difficult virtue of assembling, it is greatly improved production capacity and efficiency, while also avoiding LED light and showing dark yellow phenomenon.
Detailed description of the invention
Fig. 1 is the structural schematic diagram of the utility model.
Fig. 2 is enlarged structure schematic diagram at LED light in Fig. 1.
Fig. 3 is the electric connection circuit diagram of LED light.
Specific embodiment
The present invention will be further described with reference to the accompanying drawing.
As illustrated in fig. 1-3, a kind of gauge without light source backlight liquid crystal mould group, including light guide plate 2, the light guide plate 2 are connected in back
In optical cement frame 1, the glutinous viscous double faced adhesive tape 3 of the horizontal edge of light guide plate 2 is for gluing mucus crystalline substance LED, the notch side of the backlight glue frame 1
Plane is equipped with light trough 4, and several LED light 5 are fixedly mounted in light trough 4, and several LED light 5 are linearly electrically connected flexible circuit board 6.
As further improvement of these options, the LED light 5 is being electrically connected flexible wires by the way of welding
The turning circuit that welding section 7 connects several LED light is set on road plate 6.
As further improvement of these options, the flexible circuit board 6 is equipped with for assembling LCD liquid crystal display
Reflexed region 8.
As further improvement of these options, several LED light 8 are electrically connected at using parallel way
Power supply.
As further improvement of these options, double faced adhesive tape carries out opposite face shading using black double-sided adhesive tape
The above is only the preferred embodiment of the utility model only, is not intended to limit the utility model, all at this
Made any modifications, equivalent replacements, and improvements etc., should be included in the utility model within the spirit and principle of utility model
Protection scope within.
