In view of this, the embodiment of the present invention provides a kind of display panel, for eliminating Moire fringe, as shown in Figure 1, this hair
The display panel that bright embodiment provides, comprising: the first display module 100 and positioned at the of 100 light emission side of the first display module
Two display modules 200；Wherein, the second display module 200 is liquid crystal display die set, and the first display module 100 is used for entering directive
The light of second display module 200 is modulated.
As shown in Figure 1, the first display module 100 includes: multiple first pixel units 11 being arranged in array；Second display
Mould group 200 includes: multiple second pixel units 21 being arranged in array；Display panel further include: be located at the first pixel unit 11

Penetrating light is blue light, and quantum dot layer may include red quantum dot material and green quanta point material, then swashing in blue light
Red quantum dot material transmitting red light is given, green quanta point material emits green light, thus later can by quantum dot layer
To generate the colour mixture light of red light, green light and blue light, realizes and provide white backlight to the second display module.Also, it measures
There is no the exit directions determined for son point material stimulated light emission, therefore light is by after quantum dot layer, having certain dissipate
The effect of penetrating, destroys the figure that the periodic formed by the first pixel unit and the second pixel unit generates, therefore can be with
Eliminate Moire fringe.In addition, dispersing scattering particles 303 in quantum dot layer, the light that can be emitted the first pixel unit is into one
Step scattering, increases the light for being incident to quanta point material, to improve the launching efficiency of quanta point material.In practical applications,
Above-mentioned residuite 301 can be that transparent colloid can be by colloid after having dispersed quanta point material 302 and scattering particles 303

Light penetrates, and the red light of quantum dot layer stimulated emission and green light are reflected to light emission side, thus improves light efficiency.
Wavelength selective layers 40 can use the multiple film layer of light, and using film interference principle to can be set pairs of blue light anti-reflection,
And red light and green light are increased anti-.And anti-for the increasing of light or anti-reflection effect depends on the incidence angle that light is incident on film layer
Degree, the refractive index of film layer and the thickness of film layer, therefore can be made in the specific implementation of the material that refractive index is suitble to
Above-mentioned wavelength selective layers 40.The wavelength selective layers may include multiple sub- film layers, be directed to blue light, red light and green respectively
The wave-length coverage of light is made of the material and thickness of different refractivity.Multiple sub- film layers can be used for one group, it is more
The mode of film layer lamination setting is organized to improve the anti-reflection effect to blue light and the increasing reaction to red light and green light.By
This makes the blue light being emitted by the first pixel unit be transmitted to quantum dot layer as much as possible, to excite quanta point material, improves
The transformation efficiency of quanta point material；And the red light and green light for making quanta point material stimulated emission are as much as possible to the first picture
The direction of plain unit is reflected, to improve the utilization rate of red light and green light, thus improves light efficiency.
In the specific implementation, as shown in Figure 1, the first pixel unit 11 is at least covered in the orthographic projection of the second display module 200
One the second pixel unit 21 of lid.For example, with corresponding second pixel unit 21 of first pixel unit 11；It can also be as
Shown in Fig. 1, three the second pixel units 21 are corresponded to first pixel unit 11, or right with first pixel unit 11
Answer more second pixel units.So as to allow the first pixel unit 11 to corresponding second pixel in display
Unit 21 carries out local dimming, promotes display effect.And the quantity of corresponding second pixel unit 21 of the first pixel unit 11 is got over
It is few, then it is finer to illustrate that subregion divides, then the local dimming of higher precision may be implemented, it in practical applications, can basis
Use demand is configured, it is not limited here.
In above-mentioned display panel provided in an embodiment of the present invention, the second display module 200 is liquid crystal display die set, and first is aobvious
Show that mould group 100 can be liquid crystal display die set, can also be emissive type display module.When the first display module 100 uses liquid crystal
When showing mould group, then need that backlight module is arranged in the incident side of the first display module 100, to provide the first display module and the
The backlight of two display modules.
In a kind of enforceable mode, as shown in figure 4, the first display module 100 can be liquid crystal display die set；At this point,
First display module 100 further include: the first down polaroid 12, first set gradually along the light exit direction of the first display module
Substrate 13, the second substrate 14 and the first upper polaroid 15；First pixel unit 11 is located at first substrate 13 and the second substrate 14

In the specific implementation, above-mentioned first down polaroid 12 can be absorption-type polaroid or reflective polaroid, on first
Polaroid 15 can be reflective polaroid.When the first down polaroid 12 and the first upper polaroid 15 are using absorption-type polaroid,
There is better contrast when the first display module can be made to carry out local dimming.When the first down polaroid 12 uses reflection-type polarisation
When piece, backlight module meets the half light of 12 polarization direction of the first down polaroid to the natural light that the first down polaroid 12 is emitted
It can transmit, and the perpendicular light in the polarization direction of the other half polarization direction and the first down polaroid 12 is then reflected back toward backlight
Mould group, the polarization direction of this some light will generate variation after the reflex of backlight module reflecting plate, again to
When one down polaroid 12 is incident, then the polarization direction for some light again meets the polarization direction of the first down polaroid 12,
Thus pass through multiple reflex, the light utilization efficiency of backlight module can be improved.And when the first upper polaroid 13 is using reflection
When type polaroid, since the light of 30 stimulated emission of quantum dot layer is not polarised light, incident to the first upper polaroid 13
Excited radiation light can then be reflected back by the first upper polaroid 13 to the direction away from the second substrate side to a certain extent, because
