The pattern of random colour stop block 011 meets: the monochromatic light projected by it with the visual angle within the scope of predetermined angle of view
Chromaticity coordinates and with predetermined reference visual angle project monochromatic chromaticity coordinates between deviation be not more than predetermined threshold.
Wherein, the explanation of the visual angle colour cast of display panel:
Multiple color blocking blocks 011 in color membrane module have the function of different (colors), and the color blocking of different function (color)
The light that luminescence component 021 issues can be filtered into the monochromatic light of corresponding color by block 011, and (i.e. wavelength is concentrated mainly on a relatively narrow model
Enclose interior light), it may include: red color resistance block 011R, green color for example, with reference to multiple color blocking blocks 011 in Fig. 4 display panel

Light, green light) be mixed into, if therefore the monochromatic color (such as chromaticity coordinates) of passing through assorted stop block 011 shift, can draw
It plays colour cast and influences colour gamut.
For example, the color in the 1931 xyZ color space of CIE that chromaticity coordinates can propose for International Commission on Illumination (CIE) is sat

Gap), therefore part black matrix 013 has protruding portion, which serves as spacer material use, the material and light shielding part of the spacer material
Material it is identical, color is also identical as light shielding part, and light shielding part and dottle pin portion are that (under normal conditions, spacer material is black
Bright), i.e., light shielding part and spacer material are structure as a whole (integrated molding), therefore, have both strengthened black matrix 013 to color blocking block 011
Between light completely cut off effect, and play the role of maintaining the spacer material of color membrane module box thickness, while it is without being prepared separately, therefore simple
The technique for forming spacer material is changed.

In enclosing, thus, the problem of improving the visual angle colour cast of display panel.
Optionally, it is formed before color membrane module in a step 11, further includes: the pattern of setting color blocking block 011；
Referring to Fig. 5, the pattern for setting color blocking block 011 includes:
10a, preparation include the test panel of luminescence component 021 and test color stop block 001, and luminescence component is made to shine；Wherein,
Test color stop block 001 includes test reference part and multiple part of detecting, and test reference part is for projecting test reference visual angle
Under monochromatic light；Any part of detecting is used to project the monochromatic light at the corresponding test visual angle within the scope of predetermined angle of view.
In the step, test panel is an easy structure (only including a part of display panel), as long as can project
Monochromatic light comprising luminescence component 021 and color membrane module, the coloured silk membrane module is by a transparent substrates (such as glass substrate) and sets
The test color stop block 001 of multiple and different colors in the transparent substrates is set, these test color stop blocks 001 can use spin coating work
Skill is arranged in the transparent substrates.It can be seen that the formation process of the test panel in the step is fairly simple, thus, the display panel
Preparation method it is also fairly simple.
Wherein, its pattern of test color stop block 001 may refer to Fig. 1 and Fig. 2, i.e., the incident side of test color stop block 001 and
Size (thickness) between light emission side in the vertical direction is d0.
Meanwhile test reference part is used to project the monochromatic light of predetermined angular, which is usually main viewing angle
Degree, for example, 0 ° of viewing angle (face display panel).Preferably, as before, chromaticity coordinates and coloration that test reference part is projected
The chromaticity coordinates of three primary colours in specification sRGB does not have deviation (or deviation is in error range).Meanwhile predetermined angle of view range can
Think 0 ° to 60 °.
10b, determine what the monochromatic test reference chromaticity coordinates of test reference part injection and each part of detecting projected
Monochromatic chromaticity coordinates.
In the step, the monochromatic light of predetermined reference part injection can be calculated separately using the equation of chromaticity coordinates (x, y)
Reference chromaticity coordinates, and, with each part of detecting project monochromatic chromaticity coordinates.
Wherein, the selection (i.e. the selection of part of detecting) for testing visual angle, can be within the scope of predetermined angle of view, every 15 °
Take a visual angle for test visual angle, for example, test visual angle includes -60 °, -45 °, -30 ° ... 15 °, 30 ° ... 60 °.Certainly,
For the problem of enabling the pattern for the color blocking block 011 to be formed preferably to improve visual angle deviation, two tests of adjacent degree are regarded

Further 1 ° of each adjacent two degree interval.
10c, deviation between monochromatic chromaticity coordinates and test reference chromaticity coordinates that each part of detecting projects is judged respectively
Whether predetermined threshold is greater than.
If 10d, being not more than, the thickness for setting part corresponding with the part of detecting on color blocking block 011 is equal to the test
Partial thickness.
Wherein, the thickness for setting part corresponding with the part of detecting on color blocking block 011 is equal to the thickness of the part of detecting,
It can be, for example, the monochromatic chromaticity coordinates at 0 ° to the 45 ° visual angle that the part of detecting of test color stop block 001 projects and test are joined
The deviation between chromaticity coordinates is examined no more than predetermined threshold, then for the monochromatic of 0 ° to 45 ° visual angle of injection on color blocking block 011
Partial pattern is identical for projecting the pattern of monochromatic part at 0 ° to 45 ° visual angle as on test color stop block 001.
10e, if more than the target color coordinates of part corresponding with the part of detecting on color blocking block 011 then being set, according to this

The spectrum for trying reference section, calculates the monochromatic test reference chromaticity coordinates at the test visual angle.
In above scheme, test color stop block 001 is using the identical color blocking block of thickness everywhere, each survey of test color stop block 001
The thickness for trying part is identical as the thickness of its test reference part, therefore simplifies the monochromatic test reference color at each test visual angle
The calculating process of coordinate only needs the spectrum of collecting test reference section, i.e., calculates and appoint using the spectrum of the test reference part
The monochromatic test reference chromaticity coordinates at meaning test visual angle.

Mark calculates the target optical spectrum of part corresponding with part of detecting on color blocking block 011.
It illustrating, the equation of the chromaticity coordinates (x, y) in 1931 xyZ chrominance space of CIE is formula (1) and (2),
So when only consider color, do not consider brightness, therefore chromaticity coordinates only takes x, the value of y:
X, Y, Z are tristimulus function in above-mentioned formula (1) and (2), wherein the equation of X is formula (3):
Wherein, the equation of Y is formula (4):
Wherein, the equation of Y is formula (5):
In formula, k is coefficient,The luminance function of the predetermined color blocking block formed；
λ is the wavelength of light,Indicate the summation to the wave-length coverage (visible wavelength) in 380nm to 780nm；
P (λ) is spectral function of the light in visual angle of luminescence component transmitting；
R (λ) is the transmittance spectrum function of color blocking block；
It is Color Matching Functions.
As it can be seen that the transmittance spectrum function of chromaticity coordinates and color blocking block 011 has certain corresponding relationship, therefore, in this step
Its target optical spectrum can be calculated according to the target color coordinates of part corresponding with part of detecting on color blocking block.
Step 10e2, according to target optical spectrum, the target for calculating part corresponding with part of detecting on color blocking block 011 is penetrated
Rate.
It illustrates, transmittance spectrum function R (λ) is by spectrum-transmitance coordinate representation, then the spectrum-transmitance coordinate
Abscissa is spectra length, and ordinate is the transmitance of color blocking block 011, that is to say, that the transmittance spectrum function R of color blocking block 011
(λ) is related with the transmitance of color blocking block 011, therefore, in this step can be according to corresponding with part of detecting on color blocking block 011
Partial target optical spectrum calculates its target transmitance.
Step 10e3, according to target transmitance, the thickness of the part corresponding with part of detecting of color blocking block 011 is calculated.
It illustrates, color blocking block 011 includes predetermined reference part and multiple first parts, and predetermined reference part is for projecting
The monochromatic light at predetermined reference visual angle, any first part are used to project the monochromatic light within the scope of predetermined angle of view, first part
Transmitance, the transmitance of thickness and predetermined reference part, thickness meet formula (6):
D0/d1=LnT1/LnT0 (6)
In formula, d0 is the thickness with reference to part of detecting；
T0 is the transmitance with reference to part of detecting；
T1 is the target transmitance of first part；
D1 is the thickness of first part.
Wherein, the test of the transmitance T0 of the predetermined reference part of color blocking block 011 and thickness d 0 and test color stop block 001 is joined
Transmitance and the thickness difference for examining part are identical, therefore, in the target transmitance that first part is calculated, and collect test
In the case where the transmitance and thickness of the test reference part of color blocking block 001, first part can be calculated according to formula (6)
Thickness d 1, i.e., the thickness of part corresponding with part of detecting on color blocking block 011.
In the program, part of detecting be the monochromatic chromaticity coordinates that is projected on test color stop block 001 with reference to chromaticity coordinates
Deviation be greater than predetermined threshold part of detecting.
Certainly, in the chromaticity coordinates for the single light for being judged as projecting through it in step 10c and with reference to inclined between chromaticity coordinates
Difference can also determine its thickness d 1 using above-mentioned steps 10e1 to step 10e4 no more than the part of detecting of predetermined threshold.

Step 11b, planarization layer 012 is formed in the first substrate 01；
Step 11c, multiple grooves are formed on planarization layer 012, groove corresponds to the position of preboarding quality stop block 011,
And the pattern of groove is identical as the predetermined pattern of color blocking block 011 formed；
Step 11d, color blocking block 011 is formed in each groove respectively.
In above scheme, is formed before color blocking block 011 in the first substrate 01, nano impression or halftoning can be passed through
(half-tone) technique forms planarization layer 012 in the first substrate 01, and the pattern according to the color blocking block 011 of predetermined formation is true
