Abstract
The utility model discloses a kind of light guide plate containing fluorescent powder printed pattern, the ink logo containing yellow fluorescent powder on four sides of light guide plate positive and negative and the printing of left and right sides side, the shape of the pattern can be circular, square and diamond shape, the blue light source for using light source to be sent for LED blue chips, the pattern of the fluorescent powder of the utility model solves the problems, such as that blue light is leaked on four side of side entering type quantum dot backlight, improves the efficiency that overall picture effect improves the production of quantum dot backlight.
Description
Technical field
Flat panel TV technical field is the utility model is related to, it is more particularly to a kind of fluorescent powder printed for containing for flat panel TV
The light guide plate of pattern.
Background technology
LCD backlight is divided into traditional white light LEDs backlight and new quantum dot backlight（Quantum dot film+blue-ray LED）, amount
Son point backlight is using blue led as light source, will be put into using the optical material of quantum dot between backlight and liquid crystal panel, so that
Gay colours can be obtained by possessing the red, green, blue of sharp peaks, colour gamut meets or exceeds OLED levels, quantum dot
Backlight and traditional white light LEDs backlight photo are as follows than advantage：
1 full gamut shows advantage.
2. narrow-band continuous spectrum, color purity is high.
3.95% close to natural light, and color restoration capability is strong, and colour rendering is remarkable.
4. inorganic material.Stability is strong, long lifespan, non-aging.
5. accurate Color control.
6. efficient, energy saving is strong
By taking current side entering type quantum dot backlight as an example, assembling sequence from bottom to up is followed successively by reflector plate, light guide plate, quantum
Point film, prismatic lens and diffusion sheet.Wherein reflector plate has again passes through diffuser plate by the reflection of unemployed light source, it is possible to increase
The utilization ratio of light, is used as leakage design.Light guide plate is used to break up luminous flux, allows light to be uniformly distributed, above light guide plate
Quantum dot film have the function that incident blue light changing into white light, prismatic lens has an optically focused light enhancing effect, upper expansion it is main
Effect is the optical haze for projecting prismatic lens, and light is uniformly appeared.
Side entering type quantum dot backlight is to be shone to act on light extraction by light guide plate by blue-ray LED side entering type, due to four side quantum
Point film can not accomplish that closed covering causes surrounding leakage blue light phenomena impair occur to overall picture effect.
The content of the invention
In order to overcome drawbacks described above, the utility model provides a kind of light guide plate containing fluorescent powder printed pattern, in leaded light
The four of plate dot surface while print the printed patterns containing fluorescent powder by its four while blue light before light guide plate is gone out just with fluorescent powder effect turn
Become white light, four sides naturally not occur leaking blue light phenomenon without blue light.
The utility model in order to solve its technical problem used by technical solution be：It is a kind of containing fluorescent powder printed pattern
Light guide plate, the ink logo containing yellow fluorescent powder on four sides of light guide plate positive and negative and the printing of left and right sides side, the pattern
Shape can be circular, square and diamond shape, the blue light source for using light source to be sent for LED blue chips.
As further improvement of the utility model, the four side circular pattern of light guide plate from outside to inside diameter order
To be descending, circular maximum gauge is 5mm, be 7 ~ 10mm with spacing between any two in row, spacing between rows and rows is 3 ~
5mm；
As further improvement of the utility model, four side of light guide plate is square, and the length of side is grown from outside to inside with argyle design
Short order is from long to short, the length of side up to 5mm, is 7 ~ 10mm with the spacing in row between any two, spacing between rows and rows 3
~5mm
As further improvement of the utility model, the pattern width of light guide plate light emission side printing fluorescent powder for 35 ~
50mm, the pattern width of other three sides printing fluorescent powder is 8 ~ 10mm.
The beneficial effects of the utility model are：The pattern of the fluorescent powder of the utility model solves side entering type quantum dot backlight
The problem of blue light, is leaked on four sides, improves the efficiency that overall picture effect improves the production of quantum dot backlight.

Embodiment
In order to deepen the understanding to the utility model, the utility model is made below in conjunction with embodiment and attached drawing further
It is described in detail, which is only used for explaining the utility model, does not form the restriction to scope of protection of the utility model.
Fig. 1 shows a kind of a kind of embodiment of the light guide plate containing fluorescent powder printed pattern of the utility model, in leaded light
The ink logo 2 of four sides of 1 positive and negative of plate and the printing of left and right sides side containing yellow fluorescent powder, the shape of the pattern 2 can be with
It is circular, square and diamond shape, the blue light source for using light source to be sent for LED blue chips.
Diameter order is descending to the 1 four side circular pattern 2 of light guide plate from outside to inside, and circular maximum gauge is
5mm, is 7 ~ 10mm with the spacing in row between any two, spacing between rows and rows is 3 ~ 5mm；
1 four side of light guide plate is square, and length of side length order is that the length of side is most long from long to short from outside to inside with argyle design 2
It is 7 ~ 10mm with the spacing in row between any two, spacing between rows and rows is 3 ~ 5mm for 5mm.
Four side light emission sides of 1 positive and negative of light guide plate（Such as a sides in Fig. 1）The pattern width for printing fluorescent powder is 35
~ 50mm, other three sides（Such as tri- sides of bcd in Fig. 1）The pattern width for printing fluorescent powder is 8 ~ 10mm.
