Similar improvement is done in the case where violating intension of the present invention, therefore the present invention is not limited to the specific embodiments disclosed below.
For big visual angle colour cast problem, mainstream solution has in mostly at present, wherein MVA (Multi-domain
Vertical Alignment, more quadrant vertical orientations) type display panel mainstream is by the way of voltage, by each picture
Clear zone and dark space are divided into plain light transmission, optically show as the mixing of two kinds of V-T characteristics, to inhibit to ask in big visual angle colour cast
Topic, but which then will lead to the complexity of gamma electric voltage adjustment.
For above-mentioned big visual angle colour cast problem, the embodiment of the invention provides a kind of color membrane substrates, referring to Figure 1 and Fig. 2,
The color membrane substrates include underlay substrate 100, black matrix 200 and color blocking layer 300.
The black matrix 200 is arranged on 100 surface of underlay substrate, and limits on the underlay substrate 100 more
A transmission region, wherein the first transmission region, the second transmission region and third transmission region are distributed in the dark space of pixel region, the 4th
Transmission region, the 5th transmission region and the 6th transmission region are distributed in the clear zone of pixel region.
The color blocking layer 300 includes the first color blocking 310, the second color blocking 320, third color blocking 330 and the 4th color blocking 340,
In, first transmission region is provided with first color blocking 310, and second transmission region is provided with second color blocking
320, the third transmission region is provided with the third color blocking 330, and the 4th transmission region is provided with first color blocking
310 and the 4th color blocking 340, the 5th transmission region be provided with second color blocking 320 and the 4th color blocking 340,
6th transmission region is provided with third color blocking 330 and the 4th color blocking 340, first color blocking 310, second color
Resistance 320, the third color blocking 330 and 340 same layer of the 4th color blocking setting, and the light transmission rate of the 4th color blocking 340 is big
In the light transmission rate of other color blockings.
It is appreciated that the present embodiment is by being arranged the first color blocking 310 and the 4th color blocking 340 in the 4th transmission region, the
Third color blocking 330 and the 4th color blocking is arranged in the 6th transmission region in five transmission region the second color blockings 320 and the 4th color blocking 340
340, using different color blocking structures, the light transmittance of changing section transmission region improves the brightness of the partially transparent area, by picture
Clear zone and dark space are divided into plain light transmission, the problem of to improve big visual angle colour cast in liquid crystal display, the ash in compacting at big visual angle
Rank whiting.
First color blocking 310 is red color resistance in one of the embodiments, and second color blocking 320 is green color
Resistance, the third color blocking 330 are blue color blocking, and the 4th color blocking 340 is white color blocking, in the 4th transmission region, institute
It states in the 5th transmission region and the 6th transmission region, the face of the area of the red green blue color blocking and the white color blocking
Long-pending ratio is 1.5~2.3.
In the present embodiment, it is provided with red color resistance in first transmission region, is provided with green in the second transmission region
Color blocking is provided with blue color blocking in the third transmission region, is provided with red color resistance and white in the 4th transmission region
Color blocking is provided with green color blocking and white color blocking in the 5th transmission region, is provided with blue in the 6th transmission region
Color blocking and white color blocking.Wherein, white due to being added in the 4th transmission region, the 5th transmission region and the 6th transmission region
Color color blocking, and the light transmittance of white color blocking is greater than the light transmittance of other color blockings, therefore, the 4th transmission region, the 5th transmission region
There is higher light transmittance with the 6th transmission region, to form clear zone, that is, passes through the color blocking structure of changing section transmission region
Pixel transmittance is divided into clear zone and dark space.
It is appreciated that since pixel has been divided into dark space (corresponding to the area A in Fig. 2) and clear zone (corresponding in Fig. 2
The area B), the coloration of pixel is codetermined by the clear zone coloration and the dark space coloration, therefore the coloration of pixel region will be according to reality
Border is calculated.For example, the coloration of pixel region is S (x, y) in the present embodiment, wherein xmix=axRA+bxRB, ymix=a '
yRA+b′yRB, a, b, a ' and b ' are chromaticity coefficent, xRAAnd xRBRespectively dark space and clear zone is in RxOn coloration, yRAAnd yRBRespectively
It is dark space and clear zone in RyOn coloration.The luminous flux of pixel region is Ymix=a " YRA+b″YRB, wherein YRAAnd YRBIt is respectively dark
The luminous flux in area and clear zone, a " and b " are respectively the luminous flux coefficient of dark space and clear zone.According to calculating simulation, by it is described it is red green/
The Ratio control of the area of blue color blocking and the area of white color blocking can be effectively improved big visual angle colour cast and ask in 1.5~2.3
Topic will not also influence the coloration of picture because white light is excessive, and then influence bright-coloured degree.
In one of the embodiments, the color blocking layer 300 with a thickness of 2~4 μm.In the present embodiment, by color blocking layer 300
Thickness control in 2~4 μ ms, both can guarantee the transmitance of light, it is darker not will cause picture brightness, and can be because of color blocking
300 too thin influence picture vividness of layer.
Fig. 3 is referred in one of the embodiments, and the color membrane substrates further include planarization layer 400, the planarization
The color blocking layer 300 is arranged in backwards to the side of the underlay substrate 100 in layer 400, and covers the color blocking layer 300.It can manage
Solution, during making color blocking layer 300, light leakage, color blocking layer 300 and black matrix 200 are overlapped in order to prevent, therefore formation height
Difference.In addition, the red color resistance of same film thickness, green color blocking and blue color blocking, have difference to the penetrance of light, in order to compensate for three
Color blocking material is planted to the difference of the light transmittance of light, red color resistance, green color blocking and blue color blocking can generally take different film thickness,
In actual process, the film thickness of red color resistance and green color blocking is almost the same, and blue color blocking uses and compares red color resistance and green
The slightly thick film thickness of color blocking, therefore also will form certain difference in height between each color blocking, to influence the flatness of color membrane substrates.By
It can all be carried out on this basis in the techniques such as subsequent orientation film production and friction orientation, so the flatness of color membrane substrates can be right
Display causes very big influence, and color membrane substrates flatness is poor, forms various types of uneven display areas.This implementation
