Distance between the incidence surface 101 of plate 10 is maximum, enables the air blanketing formed by the second dimming section 1022 to further enhance
The refraction effect of light, to expand the light range of exposures of light source 20, that improves light source 20 goes out light, light mixing effect, and then reduces
Luminous dark space between light source 20, owing to can strengthen the refraction effect of light by the second dimming section 1022, moreover it is possible to reduces and leads
Distance between tabula rasa 10 and the light source 20 and light utilization efficiency of light source 20 can be improved, and then facilitate implementation the narrow frame of display device
Design.
In a kind of specific embodiment, as shown in Fig. 3, Fig. 4 and Fig. 5 structure, light guide plate 10 deviates from light at groove 102
The side in source 20 is provided with the quantum dot filling slot 103 arranging parallel with groove 102 and connecting, and fills in quantum dot filling slot 103
Have quantum dot 1031, quantum dot 1031 can under the exciting that light source 20 launches light generation complementary color light to launch with light source 20
Light is mixed to form full-color light.
The light guide plate 10 of above-mentioned backlight module is provided with quantum dot filling slot 103 parallel arrangement of with groove 102, and at quantum
Point filling slot 103 is filled with quantum dot 1031, owing to quantum dot 1031 can generation under the exciting that light source 20 launches light
Complementary color light, and the light launched with light source 20 of complementary color light mixes and can form full-color light, therefore, it is possible to reduce in backlight module
The kind of different colored light sources 20, and the colour gamut of light source 20 can be improved；Simultaneously as the second dimming section 1022 can make light towards
The middle part refraction in gap between light source 20, light L1, light L2, light L4 and the light L5 launched such as light source in Fig. 3, and
And the light of refraction can excite the quantum dot 1031 of corresponding position to produce complementary color light, and then form full-color light, therefore, by setting
Quantum dot 1031 in light guide plate 10 can also increase light source 20 and launch the region that light reaches, and reduces backlight module further
Luminous dark space.
Specifically, light source 20 can be the light source 20 launching blue light.
When the light source 20 of above-mentioned backlight module launches blue light, quantum dot filling slot 103 is filled with by blue light excitation energy
Enough produce HONGGUANG and the quantum dot 1031 of green glow, the blue light that the HONGGUANG of quantum dot 1031 generation and green glow are launched with light source 20
Full-color light can be produced, and then entrance display floater shows.
Light source 20 can also be to launch HONGGUANG or the light source 20 of green glow, corresponding, quantum dot filling slot 103 is filled with and is subject to
HONGGUANG excites the quantum dot 1031 that can produce blue light and green glow, or is filled with by green glow excitation energy in quantum dot filling slot 103
Enough producing blue light and the quantum dot 1031 of HONGGUANG, the light making light source 20 send by quantum dot 1031 forms full-color light, with full
The foot display floater requirement to backlight.
Therefore, when using the light guide plate 10 with quantum dot 1031, backlight module can use solid color light source 20 i.e.
The requirement of display floater can be met such that it is able to reduce the demand to shades of colour light source 20 in backlight module, and light can be improved
The colour gamut in source 20, moreover it is possible to reduce the luminous dark space of backlight module.
It addition, light source 20 can be LED light source 20, as launched the LED light source 20 of blue light.
Owing to LED light source 20 has that volume is little, voltage is low, brightness is high and low in calories, therefore, LED light source is used
The backlight module of 20 has that volume is little, brightness is high and heat dispersion requires low feature.
Further, the centrage O2 of the second dimming section 1022 is arc.
In order to improve the second dimming section 1022 further, light source 20 is launched the refraction effect of light, and then reduces backlight mould
The luminous dark space of group, in actual production process, the centrage O2 of the second dimming section 1022 can be arc, meanwhile, as Fig. 3 ties
Shown in structure, the centrage O2 of the second dimming section 1022 can also be V-type, and the angle a of the V-type of centrage O2 is more than or equal to
140 ° and less than 180 °, such as, the angle a of V-type be specifically as follows 140 °, 143 °, 145 °, 148 °, 150 °, 154 °, 158 °,
160°、163°、166°、170°、172°、175°、178°、179°；When the centrage O2 of the second dimming section 1022 is V-type, also
Be conducive to the manufacturing of the second dimming section 1022, therefore, it is possible to simplify manufacturing process, improve production efficiency and the accuracy of manufacture.
It addition, the angle a of the V-type of the centrage O2 of the second dimming section 1022 can also be according between adjacent light source 20
Away from regulating accordingly, light source 20 is launched the refraction effect of light optimizing the second dimming section 1022, and then reduce backlight mould
The luminous dark space of group.
Further, when the angle a of V-type is 163 °, in above-mentioned light guide plate 10, the second dimming section 1022 of groove 102 is to light source
20 refraction effects launching light reach best, make the luminous dark space of the incidence surface 101 of light guide plate 10 and light guide plate 10 and light
Distance minimization between source 20, and then make the frame of display device minimize.
On the basis of above-mentioned various backlight modules, as shown in Fig. 3 structure, the incidence surface 101 and second of light guide plate 10 is adjusted
Relative position, light portion 1022 is provided with catoptric arrangement 30.
By being arranged on the catoptric arrangement at the position of the incidence surface 101 of the light guide plate 10 relative with the second dimming section 1022
30, light guide plate 10 can be made to be internally reflected to the light back of catoptric arrangement 30 in light guide plate 10, in preventing light guide plate 10
Light shines outside light guide plate 10 by the incidence surface 101 of light guide plate 10, it is simple to the light of the gap location between raising light source 20
The brightness of the gap location between line density, and then raising light source 20, reduces the luminous dark space between light source 20 further, improves light
The light utilization efficiency in source 20.Further, the catoptric arrangement 30 of the above-mentioned incidence surface 101 being arranged at light guide plate 10 can be to be attached at leaded light

Reflecting layer.
As shown in Fig. 3 structure, the light L3 that light source 20 is launched and light L6 occurs when being irradiated to the second dimming section 1022
Total reflection, makes light carry out multiple reflections in the luminous dark space of the incidence surface 101 of light guide plate 10, and then improves in luminous dark space
Light luminance, in order to improve the total reflection in luminous dark space of the light source 20 light emitted line further, light source 20 can be set
The light penetrated is when the angle that the incidence surface 101 with light guide plate 10 is formed is in 35 °～40 °, and light can be totally reflected,
Such as the light L3 in Fig. 3 and light L6, and, the light that light source 20 is launched is formed at the incidence surface 101 with light guide plate 10
Angle is specifically as follows 35 °, 36 ° 36.6 °, 37 °, 37.2 °, 37.5 °, 37.8 °, 38.5 °, 39.4 °, 40 °.
It addition, an embodiment of the present invention additionally provides display device, this display device includes display floater and above-mentioned reality
Execute any one backlight module that example provides.
After display device uses any one backlight module provided in above-described embodiment, by the groove in light guide plate 10
