For making those skilled in the art be more fully understood that technical scheme, below in conjunction with the accompanying drawings and be embodied as
A kind of color membrane substrates provided by the present invention and preparation method thereof, display floater and display device are made to retouch the most in detail by mode
State.
Embodiment 1:
The present embodiment provides a kind of color membrane substrates, as shown in Figures 2 and 3, including substrate 1 and setting coloured silk on substrate 1
Film layer 2, color membrane substrates 5 includes multiple region 3, and multiple regions 3 phase is spliced；Along the stitching direction in region 3, regional 3 all wraps
Include the splicing regions 31 at corresponding piece 4 and away from the central area 32 at piece 4；Correspondence is centrally located the color film in region 32
Layer 2 at least local thickness is distributed in the thickness of the color film layer 2 of splicing regions 31 more than correspondence, and its thickness difference D1 is less than or equal to using
In with the metallic diaphragm 61 of corresponding splicing regions 31 on the color membrane substrates 5 array base palte 6 to box and the gold of corresponding central area 32
Belong to the thickness difference D2 of film layer 61.
In the present embodiment, region 3 be shaped as bar shaped.It should be noted that the shape in region 3 can also be other shape
Shape, as regular in circle or polygon etc. or irregular shape.
Wherein, metallic diaphragm 61 thickness of corresponding splicing regions 31 and the metal of corresponding central area 32 on array base palte 6
Film layer 61 thickness refers both to the final superposition thickness of all metallic diaphragms 61 on the array base palte 6 of corresponding each zones of different, i.e. makes
The gross thickness of the metallic diaphragm 61 of corresponding splicing regions 31 or central area 32 on array base palte 6 after Bei.
It is distributed in splicing regions more than correspondence by the color film layer 2 at least local thickness making correspondence be centrally located region 32
The thickness of the color film layer 2 of 31, and its thickness difference D1 is less than or equal to for spelling corresponding with on the color membrane substrates 5 array base palte 6 to box
Meet the metallic diaphragm 61 in region 31 and the thickness difference D2 of the metallic diaphragm 61 of corresponding central area 32, it is possible to relatively reduced to box after
Splicing regions 31 and its corresponding metallic diaphragm 61 between the first gap H1 and central area 32 at least local and its
The corresponding difference between the second gap H2 between metallic diaphragm 61, thus relatively reduce the aobvious of corresponding splicing regions 31
Show the light penetration deviation when display between the viewing area of region and corresponding central area 32, then reduce corresponding spelling
Connect the aberration when display between the viewing area in region 31 and the viewing area of corresponding central area 32, and then improve color film
The image quality bad phenomenon that box gap inequality after box is caused by substrate 5 and array base palte 6.
In the present embodiment, color film layer 2 includes red color film 21, green tint film 22 and blue color film 23, during correspondence is distributed in
The red color film 21 in heart region 32 and the thickness of green tint film 22 are more than the thickness of blue color film 23, and correspondence is centrally located district
The red color film 21 in territory 32 and the thickness of green tint film 22 are all higher than the thickness that correspondence is distributed in the color film layer 2 of splicing regions 31.
Corresponding in central area 32, due to the light through red color film 21 and green tint film 22 along with the increase in box gap transmitance
Increase, and transmitance reduces along with the increase in box gap through the light of blue color film 23；It is therefore corresponding in central area 32,
Light penetration through blue color film 23 reduces, and is increased by the light penetration of red color film 21 and green tint film 22；
This is easily caused the picture color jaundice of corresponding central area 32, by correspondence is centrally located the red color film 21 in region 32
With the thickness that the thickness of green tint film 22 is set greater than blue color film 23, correspondence can be made to be centrally located the red color in region 32
The color blocking of film 21 and green tint film 22 increases, and color blocking increases can make the light penetration of red color film 21 and green tint film 22 subtract
Little, so that the light penetration difference of the red color film 21 of central area 32 and green tint film 22 and blue color film 23 reduces,
And then reduce central area 32 and differ greatly due to the trichroism light transmission rate of caused red, green and blue bigger to box back box gap
And the problem of central area 32 yellowish brought, there is color offset phenomenon in the display that central area 32 has been reduced or avoided.
Meanwhile, from the point of view of whole color membrane substrates 5, due to the increase meeting to box gap of the relative splicing regions 31 in central area 32
The light penetration directly resulting in the relative splicing regions 31 in central area 32 increases, by making correspondence be centrally located region 32
The thickness of red color film 21 and green tint film 22 is distributed in the thickness of the color film layer 2 of splicing regions 31, i.e. center more than correspondence
The red color film 21 in territory 32 and the thickness of green tint film 22 more than the thickness of the color film layer 2 of splicing regions 31, red color film 21 and green
The increase of color film 22 thickness can correspondingly increase its color blocking, thus reduces its light penetration, therefore, by increasing center
The red color film 21 in region 32 and the thickness of green tint film 22, it is possible between corresponding compensation central area 32 and splicing regions 31
Light penetration difference, and then it is bad to improve color membrane substrates 5 and array base palte 6 image quality that caused uneven to the box gap after box
Phenomenon.
In the present embodiment, the thickness that correspondence is centrally located the red color film 21 in region 32 and green tint film 22 is equal.By
Essentially identical to effect tendency and the degree of its light penetration in the color blocking of red color film 21 and green tint film 22, it is advantageous to
The red color film 21 of central area 32 and the thickness of green tint film 22 are set to equal.
In the present embodiment, correspondence is centrally located the blue color film 23 in region 32 and the corresponding coloured silk being distributed in splicing regions 31
The thickness of film layer 2 is equal.Wherein, correspondence is distributed in the color film layer 2 of splicing regions 31 and also includes red color film 21, green tint film 22
With blue color film 23, and the thickness of red color film 21, green tint film 22 and blue color film 23 is equal.I.e. in the present embodiment, corresponding
It is centrally located the red color film 21 in region 32 and the thickness of green tint film 22 is distributed in the color film of splicing regions 31 more than correspondence
The thickness of layer 2, by increasing central area 32 red color film 21 and the thickness of green tint film 22, it is possible to increase central area 32
Color blocking, thus reduce the light penetration of central area 32, the reduction amount of this light penetration can compensate for central area 32
The amount of the increase of the light penetration caused due to the increase to box gap, and then make central area 32 and splicing regions 31
Light penetration reaches unanimity, and finally reduces viewing area and the viewing area of corresponding central area 32 of corresponding splicing regions 31
Aberration when display between territory, improves color membrane substrates 5 and array base palte 6 to the box gap image quality that caused of inequality after box
Bad phenomenon.
In the present embodiment, the thickness of the metallic diaphragm 61 of the corresponding central area 32 of array base palte 6 is less than corresponding splicing regions
The thickness of the metallic diaphragm 61 of 31；Along the stitching direction in region 3, central area 32 and the width accounting of splicing regions 31 and array
The width accounting of the metallic diaphragm 61 that on substrate 6, thickness is different is equal.It is arranged such, district can be centrally located by adjusting correspondence
The thickness of the color film layer 2 in territory 32 realizes the reasonable compensation to box gap difference to corresponding central area 32 with splicing regions 31,
It is thus possible to more accurately reduce between the viewing area of corresponding splicing regions 31 and the viewing area of corresponding central area 32
Aberration during display, improves the image quality bad phenomenon that the box gap inequality after box is caused by color membrane substrates 5 and array base palte 6.
In the present embodiment, color membrane substrates 5 also includes that black matrix 7, black matrix 7 are arranged on the one of the close substrate 1 of color film layer 2
Side, and the interval region that black matrix 7 is between red color film 21, green tint film 22 and blue color film 23.Black matrix 7 can be right

In the present embodiment, color membrane substrates 5 also include chock insulator matter 8, chock insulator matter 8 be arranged on black matrix 7 back to the one of substrate 1
Side, and chock insulator matter 8 correspondence be distributed in black matrix 7 distribution region.Chock insulator matter 8 can be to the color membrane substrates 5 arranging box and array
Substrate 6 is formed and supports, so that keeping certain box gap between color membrane substrates 5 and array base palte 6, in order to fill out in box gap
Fill the liquid crystal that light is transmitted, and ensure that liquid crystal has enough arrangement spaces in box gap.
Said structure based on color membrane substrates, the present embodiment also provides for the preparation method of this color membrane substrates a kind of, including: adopt
On substrate, form the figure including color film layer with patterning processes, be correspondingly formed at least local of color film layer in central area

Wherein, the first duration is less than the second duration.It should be noted that this method is directed to use positivity coloured silk film glue
Color film layer, i.e. for positivity coloured silk film glue, through exposure light irradiate photoresist be removed after development, unexposed light
The photoresist irradiated is retained after development.In red color film pattern and the region of green tint film pattern of corresponding central area,
The irradiation time controlling exposure light is shorter, so that the red color film pattern of corresponding central area and the district of green tint film pattern
The red color film film layer of territory removal after development and the thinner thickness of green tint film film layer；And in the redness of corresponding splicing regions
Color film pattern and the region of green tint film pattern, the irradiation time controlling exposure light is longer, so that corresponding splicing regions
