Description
Technical field
The utility model is related to display screen technology fields, and in particular to a kind of backlight module of glass back plate leaded light imaging.
Background technology
Backlight module is one of the key part and component of panel of LCD, and function is well-off brightness and divides
The uniform light source of cloth, enables liquid crystal display normally to show image.Conventional backlight module is mainly by light source, light guide plate, reflection
The compositions such as piece, optical diaphragm, backlight module can be divided into side entering type, straight-down negative, hollow type light-source structure, due to downward back optical mode
Group needs more LED light source, increases cost of manufacture, therefore gradually eliminated；Currently, most commonly seen structure is side entering type
Backlight module is emitted to the light guiding points of light guide plate by LED point light source, and light guiding points dissipate incident light, to convert point light source
For area source.The mode of printing or laser dotting is usually used and makes site in guide-lighting back, and the making of light guide plate
Cost is higher and frangible, and fragmentation after image simple glass equally generates wedge angle, is easy to scrape in process and hurt sb.'s feelings.Therefore, there is an urgent need for one
Kind back light module unit structure, can replace light guide plate, security performance is higher, i.e., does not influence light guide effect, can also reduce cost.
Utility model content
In view of the above problems, the utility model provides a kind of backlight module of glass back plate leaded light imaging, the backlight module
Ultra-clear glasses plate is used instead of light guide plate, security performance is higher, and production cost is relatively low.
To achieve the above object, the utility model solves by the following technical programs：
A kind of backlight module of glass back plate leaded light imaging, including glass back plate, surpassing on the upside of the glass back plate
White glass plate, the diffusion sheet on the upside of the ultra-clear glasses plate, the brightening piece on the upside of the diffusion sheet and be located at institute
The light source of ultra-clear glasses plate side is stated, the surface that the glass back plate is close to ultra-clear glasses plate side is equipped with reflective ink
Layer, the reflective ink layer upper surface are equipped with several sites.
Specifically, the side of the ultra-clear glasses plate far from the light source is additionally provided with heat dissipation aluminum strip.
Specifically, the glass back plate is tempered glass.
Specifically, the ultra-clear glasses plate is optical grade ultra-clear glasses.
Specifically, the reflective ink layer is white reflection ink.
Specifically, the face that the diffusion sheet is close to ultra-clear glasses plate side is frosting.
The utility model has the beneficial effects that：
First, the guide-lighting mode in traditional back light module unit structure is by the way of printing or laser dotting in leaded light
Back makes site, is radiated on site by side entering type light source, to guide-lighting.This structure is using ultra-clear glasses plate instead of leading
Tabula rasa, and white reflection ink first is printed in the upper surface of glass back plate, then in white reflection ink layer upper surface printing net
Point is similar to light guide plate leaded light principle and carries out leaded light, avoids using light guide plate, reduce production cost；
Second, optical grade ultra-clear glasses and glass back plate are the material of tempered glass, and tempered glass is safety glass, if
Accident fragmentation when processing, fragment can be broken into uniform little particle and without the wedge angles of universal glass knife-like, improve safety；
Third, diffusion sheet are glass diffuser plate, are frosting on the inside of diffuser plate, the light after the transmitting of ultra-clear glasses plate reaches
Frosting, frosting adjustable light, the refraction for making light generation different directions, reflection and scattering, to change the traveling of light
Route realizes that incident light fully dissipates the effect that color generates optics diffusion with this；
4th, one side of the ultra-clear glasses plate far from light source is additionally provided with heat dissipation aluminum strip, enhances the thermal diffusivity of backlight module
Energy.
Description of the drawings
Fig. 1 is the structural schematic diagram for the backlight module that a kind of glass back plate leaded light of the utility model is imaged.
Reference numeral is：Glass back plate 1, reflective ink layer 11, site 12, ultra-clear glasses plate 2, diffusion sheet 3, brightening piece 4,
Light source 5, heat dissipation aluminum strip 6.
Specific implementation mode
The utility model is described in further detail with reference to embodiment and attached drawing, but the implementation of the utility model
Mode is without being limited thereto.
As shown in Figure 1：
A kind of backlight module of glass back plate leaded light imaging, including glass back plate 1, the ultrawhite positioned at 1 upside of glass back plate
Glass plate 2, the diffusion sheet 3 positioned at the upside of ultra-clear glasses plate 2, the brightening piece 4 positioned at 3 upside of diffusion sheet and it is located at ultrawhite glass
The light source 5 of 2 side of glass plate, the surface that glass back plate 1 is close to 2 side of ultra-clear glasses plate are equipped with reflective ink layer 11, reflective ink
11 upper surface of layer are equipped with several sites 12.
Preferably, side of the ultra-clear glasses plate 2 far from light source 5 is additionally provided with heat dissipation aluminum strip 6, enhances the heat dissipation of backlight module
Performance.
Preferably, glass back plate 1 is tempered glass, and tempered glass is safety glass, if accident fragmentation when processing, fragment meeting
It is broken into uniform little particle and without the wedge angle of universal glass knife-like, improves safety.
