Detailed description of the invention
Embodiments provide a kind of display base plate, its manufacture method, display panels and display device, in order to
Promote the transmitance of display floater further.
In order to make the object, technical solutions and advantages of the present invention clearer, below in conjunction with accompanying drawing the present invention made into
One step ground describes in detail, it is clear that described embodiment is only a part of embodiment of the present invention rather than whole enforcement
Example.Based on the embodiment in the present invention, those of ordinary skill in the art are obtained under not making creative work premise
All other embodiments, broadly fall into the scope of protection of the invention.
The display base plate of specific embodiment of the invention offer, its manufacture method, display surface are provided below in conjunction with the accompanying drawings
Plate and display device.
As in figure 2 it is shown, the display base plate that the embodiment of the present invention provides, including: underlay substrate 21, it is arranged on underlay substrate
Sub-pix color blocking 22 in array distribution and be arranged on underlay substrate 21 light shield layer for separating each sub-pix color blocking 22
23；Wherein, sub-pix color blocking 22 comprises blue color blocking B and non-blue color blocking (R and G in such as Fig. 2)；The thickness of blue color blocking B
Degree is more than the thickness of non-blue color blocking (R and G).
In the specific implementation, the material of blue color blocking has character as shown in Figure 3, and the abscissa in Fig. 3 represents wavelength model
Enclosing, vertical coordinate represents transmitance.When generally using the material of high colour gamut to make blue color blocking in the prior art, its transmitance
Curve is as shown in the curve a in Fig. 3, and now the thickness of blue color blocking can be 2.1 μm.The peak value of the longitudinal axis is the biggest, represents transmitance
The highest.The width of transverse axis can represent colourity in a sense, and the representability of the narrowest then color of width of crest is the best, then colour gamut
The highest.When the material using low colour gamut makes blue color blocking with same thickness, its transmittance curve such as the curve in Fig. 3
Shown in b, curve a and curve b contrast, when the material using low colour gamut makes the blue color blocking of same thickness, its
Transmitance is higher, but the width of crest is the biggest simultaneously, and colour gamut is relatively low.Now, this kind low colour gamut material is used to make thickness
When being the blue color blocking of 2.8 μm, its transmittance curve is as shown in the c in Fig. 3, and its transmitance and colour gamut can reach raw material institute
Degree to which.Therefore, in the above-mentioned display base plate that the embodiment of the present invention provides, blue color blocking uses the resinous wood of low colour gamut
Material is made.
Owing to, for commaterial, increasing its thickness when making and can reach the effect improving colour gamut.Therefore, blue
The thickness of color color blocking, more than the thickness of non-blue color blocking, in the case of other parameter is the most immovable, uses relatively raw material colour gamut
Relatively low material makes blue color blocking, and increases the thickness of blue color blocking, i.e. can reach the colour gamut that raw material can reach,
Its transmitance remains in that higher level simultaneously.In region corresponding to color blocking blue in 380-780nm wave-length coverage
Liquid crystal cell thickness is the least, then the transmitance in this region is the highest, and in region corresponding to other color color blocking (non-blue color blocking)
The biggest transmitance of liquid crystal cell thickness is the highest.Therefore, the thickness of blue color blocking, more than the thickness of non-blue color blocking, can make display surface
During plate, reach to reduce the liquid crystal cell in region corresponding to blue color blocking thick simultaneously, increase in region corresponding to non-blue color blocking
Liquid crystal cell is thick, thus the transmitance of each color can be made to improve simultaneously, while the colour temperature of display floater can be kept constant, improves
The transmitance of display floater.
In the specific implementation, as in figure 2 it is shown, above-mentioned sub-pix color blocking may also include that red color resistance R and green color blocking G；
Light shield layer 23 can use black matrix.When the above-mentioned display base plate using the embodiment of the present invention to provide, can by except blue color blocking B with
The thickness of outer non-blue color blocking (such as, red color resistance R and green color blocking G) keeps consistent, or keeps former level, to reduce system
Complexity during work, makes the transmitance of the display base plate being made promote simultaneously.It should be noted that in reality
When border makes each colored color blocking, the thickness of colored color blocking fluctuates in a less scope and is all considered as made colored color blocking thickness
Spend equal.Such as, when the thickness of red color resistance R with green color blocking G is set to 2.2 μm, red color resistance R or green when making
As long as within the thickness of color color blocking G is maintained at 2.18-2.23 μ m, all can be considered meet making standard, i.e. red color resistance R with
The undulating value that the thickness of green color blocking G is maintained in 0.05 μ m on the basis of 2.2 μm all meets making standard.
Further, it is considered to present stage each color color blocking material, the liquid crystal cell thickness of display floater and display floater are overall
The requirement of thickness and restriction, blue color blocking is positively retained within the scope of 0.4 μm-0.8 μm with the thickness difference of non-blue color blocking.And
Arranging the situation outside the blue color blocking thickness difference with non-blue color blocking exceeds range above according to actual needs, the present invention is real
Execute example not limit at this.
The above-mentioned display base plate that the embodiment of the present invention provides can be color membrane substrates or array base palte (example when reality is applied
As: COA array base palte).By increasing the thickness of blue color blocking, while keeping the colour temperature of each color color blocking, improve display surface
The transmitance of plate.
Based on same inventive concept, the embodiment of the present invention additionally provides a kind of display panels, including any of the above-described aobvious
Show substrate, may also include opposite substrate that is relative with this display base plate and that put.Such as, as shown in Figure 4, display base plate is color film base
Plate 21, the substrate put in contrast is array base palte 24, and each pixel region in color membrane substrates 21 includes three sub-pictures
Plain color hinders 22 red color resistance R, green color blocking G and blue color blocking B.As seen from Figure 4, the thickness in blue color blocking B is big
When the thickness of non-blue color blocking (R, G), the liquid crystal cell thickness in region corresponding to blue color blocking B is less than non-blue color blocking (R, G)
Liquid crystal cell in corresponding region is thick.
Use the liquid crystal cell in region corresponding to each color color blocking that above-mentioned set-up mode is because in display floater thick
With transmitance, there is relation (transverse axis represents that wavelength, the longitudinal axis represent transmitance) as shown in Figure 5: for red color resistance R and green
For color blocking G, increasing the liquid crystal cell in region corresponding to red color resistance R thick, the transmitance in this region improves the most therewith；Increase
Liquid crystal cell in region corresponding to green color blocking G is thick, and the transmitance in this region improves the most therewith, 480nm-780nm ripple in Fig. 5
Section belongs to the wave band of green glow and HONGGUANG, and as seen from Figure 5, along with thick being continuously increased of liquid crystal cell, (liquid crystal cell is thick to be increased by 2.7 μm
Add to 3.9 μm), the transmitance of corresponding 480nm-780nm wave band increases therewith.And for blue color blocking B, reduce blue color
Liquid crystal cell in region corresponding to resistance B is thick, and the transmitance in this region improves therewith, and the 380nm-480nm wave band in Fig. 5 belongs to
Blue wave band is as seen from Figure 5, along with thick constantly the reducing (liquid crystal cell thickness is decreased to 2.7 μm by 3.9) of liquid crystal cell, corresponding
The transmitance of 380nm-480nm increases therewith.
Thus, suitably the distance between color membrane substrates 21 and array base palte 24 can be increased when making above-mentioned display floater
Greatly, increase the thickness of blue color blocking B so that the liquid crystal cell thickness in region corresponding to blue color blocking B reduces simultaneously, rather than blue color
Liquid crystal cell thickness in region corresponding to resistance (R, G) increases, to increase the transmitance in region corresponding to each color color blocking, due to respectively
The transmitance of color color blocking has promoted, and the transmitance of the light of the most each color increases simultaneously, and each color of light is in white light
Shared energy proportion does not change, thus keeps colour temperature constant and improve the transmitance of display floater.
In the specific implementation, for simplifying processing technology, the thickness of the non-blue color blocking in addition to blue B can be kept one
Cause, thus after to box, the liquid crystal cell thickness in region corresponding to non-blue color blocking (R, G) is the most equal.According to above-mentioned to each coloured silk
The explanation of the thickness calibration of color color blocking, in the one-tenth-value thickness 1/10 of each color color blocking smaller range before and after reference value (such as,
0.05 μm) fluctuation time, the value that corresponding liquid crystal cell is thick also can fluctuate within the range, and liquid crystal cell within the range is thick
It is accordingly to be regarded as box thickness value equal.Generally, the liquid crystal cell thickness in region corresponding to blue color blocking B may be provided at 2.5 μm-4.0 μ m
Within, and the liquid crystal cell thickness in region corresponding to non-blue color blocking (R, G) in addition to a blue may be provided at 3.0 μm-4.5 μm models
Within enclosing, and keep the liquid crystal cell thickness in region corresponding to blue color blocking B less than the liquid in non-blue color blocking (R, G) corresponding region
Brilliant box is thick.
By above-mentioned in region corresponding to red color resistance, green color blocking and the thickness of blue color blocking and each color color blocking
The relation that liquid crystal cell is thick understands.According to the present invention, for red color resistance and green color blocking, the material system of high colour gamut can be used
Make, in manufacturing process, reduce red color resistance and/or the thickness of green color blocking simultaneously, to increase red color resistance and/or green color
Liquid crystal cell in the corresponding region of resistance is thick, improves the transmitance in this region.
As follows in case of only changing blue color blocking thickness with display panels comparative illustration of the prior art

Two parameters thick with the liquid crystal cell in the thickness changing color blocking and corresponding region of the display panels in the embodiment of the present invention
The comparison diagram of the transmittance curve of rear corresponding region.In prior art, the thickness of red color resistance, green color blocking and blue color blocking is all
Being 2.1 μm, the liquid crystal cell thickness in region corresponding to each color color blocking is 3.0 μm.Wherein, the transmitance that red color resistance is corresponding is bent
Line is r1, and transmittance curve corresponding to green color blocking is g1, and transmittance curve corresponding to blue color blocking is b1.Now by blueness color blocking
Thickness increase to 2.8 μm, the distance of each color color blocking substrate on the other side is increased, so that red color resistance and green color
Liquid crystal cell thickness in the corresponding region of resistance increases to 3.4 μm, and the liquid crystal cell thickness in region corresponding to blue color blocking is reduced to 2.7
μm；Wherein, transmittance curve corresponding to red color resistance is r2, and transmittance curve corresponding to green color blocking is g2, blue color blocking pair
The transmittance curve answered is b2.By the comparison diagram shown in Fig. 6 a it can be seen that in the wave band of 380nm-780nm, to whole liquid
For LCD panel, the box thickness of display panels increases, and red color resistance and green transmitance corresponding to color blocking substantially carry
Height, and blue transmitance corresponding to color blocking has and declines more by a small margin, and use change parameter after display panels whole
Body transmitance is as shown in the curve B in Fig. 6 b, compared with the transmittance curve A of display panels of the prior art, and liquid crystal
