Problems solved by technology

In order to improve the outdoor readability of liquid crystal displays, people have proposed transflective technology, which improves the use effect of liquid crystal displays in sunlight to a certain extent. However, due to its own structure, transflective liquid crystal The design requires two liquid crystal cells with different thicknesses in one sub-pixel, which makes it very difficult in optical design and manufacturing process, especially in the rubbing process, there will be many dead angles that cannot be aligned. At the same time, the liquid crystal cell design mode used for the transflective type basically does not have wide viewing angle characteristics
[0006] At present, it is pr

Embodiment 1

[0033] Such as figure 1 As shown, a color filter of the present invention includes a base substrate 1, a color filter layer and a black matrix 3, the black matrix 3 has a plurality of openings for setting the color filter layer, and the black matrix 3 is close to the substrate A first transparent conductive layer 2 is provided on one side of the base substrate 1 , a second transparent conductive layer 4 is provided on a side of the black matrix away from the base substrate 1 , and the black matrix 3 is made of an electrochromic material.

[0034] The base substrate 1 can be made of glass, quartz, transparent resin or the like.

[0035] Electrochromic materials can undergo stable and reversible color changes under the action of an external electric field. When the first transparent conductive layer 2 and the second transparent conductive layer 4 are energized, the black matrix made of electrochromic material appears black, which is suitable for indoor use; when the first trans...

Embodiment 2

[0041] The present invention also provides a display device, which includes the color filter described in the first embodiment above. The display device may be any product or component with a display function, such as a liquid crystal panel, a mobile phone, a tablet computer, a television set, a monitor, a notebook computer, a digital photo frame, a navigator, and the like. It includes the color filter and the switch element array substrate described in the first embodiment. The black matrix of the color filter of the display device is made of electrochromic material, and a first transparent conductive layer and a second transparent conductive layer are arranged on both sides of the black matrix, and by adjusting the first and second transparent conductive layers The voltage between them controls the transmittance of the black matrix in the color filter, so that the transmittance of the black matrix can be adjusted, thereby changing the transmittance of the color filter, so th...

Embodiment 3

[0043] The present invention also provides a method for manufacturing the color filter of Embodiment 1, which includes the following steps:

[0044] S1, forming a first transparent conductive layer 2 on the base substrate 1;

[0045]Specifically, a transparent conductive film layer can be formed on the base substrate by means of sputtering, spraying, coating or evaporation;

[0046] It should be noted that when the first transparent conductive layer covers the entire base substrate, the above-mentioned transparent conductive film layer is the first transparent conductive layer; when the first transparent conductive layer only covers the area where the black matrix is ​​located, the transparent conductive film is formed After layering, the designed pattern needs to be formed through a patterning process; wherein, the patterning process usually includes processes such as photoresist coating, exposure, development, etching, and photoresist stripping.

[0047] S2, forming a black...

Abstract

The invention relates to crystal displaying technology, and discloses a color filter. The color filter comprises a base substrate, a color filter layer and a black matrix. A first transparent conducting layer is arranged at one side, near the base substrate, of the black matrix, a second transparent conducting layer is arranged at one side, away from the base substrate, of the black matrix, and the black matrix is made of electrochromic materials. The invention further discloses a displaying device including the color filter and a manufacturing method of the color filter. The black matrix of the color filter is made of the electrochromic materials, the first transparent conducting layer and the second transparent conducting layer are respectively arranged at two sides of the black matrix, the transmittance of the black matrix in the color filter is controlled by adjusting the voltage between the first transparent conducting layer and the second transparent conducting layer to enable the transmittance of the black matrix to be adjustable, and therefore the light transmittance of the color filter is changed, and the displaying device is good in readability outdoors, and good in displaying effect indoors at the same time.

Description

technical field [0001] The invention relates to the technical field of liquid crystal display, in particular to a color filter, a manufacturing method of the color filter and a display device. Background technique [0002] At present, with the development of science and technology and the progress of society, liquid crystal displays have been more and more widely used by people, and play a vital role in industrial production and people's lives. [0003] ADS (ADvanced Super Dimension Switch, advanced ultra-dimensional field switching technology) forms a multi-dimensional electric field through the electric field generated by the edge of the slit electrode in the same plane and the electric field generated between the slit electrode layer and the plate electrode layer, so that the slit in the liquid crystal cell All oriented liquid crystal molecules between the electrodes and directly above the electrodes can be rotated, thereby improving the working efficiency of the liquid c...
