Abstract

The present invention discloses a color filter which is provided with a transparent baseplate; a shading zone is formed on the baseplate and a plurality of pixels are also distributed on the baseplate, wherein, each pixel is provided with a first color zone, a second zone and a third zone, in particular the first color zone, the second color zone and the third color zone of each pixel are centrosymmetric hexagons, and with an arbitrary first color zone as the center on the transparent baseplate, six mutually spaced second color zones and third color zones are faveolately in scarf joint around. The color filter with the structure has good color display effect and can weaken sawtooth in the margin of image when the image is displayed obliquely.

Description

A kind of colored filter

Technical field

The present invention relates to a kind of colorized optical filtering chip technology, especially relate to a kind of structure of colored filter.

Background technology

LCD (liquid crystal display, be LCD) be present main flow display, colored filter part wherein provides colored demonstration for LCD, and the display device of forming with the collocation of thin film transistor (TFT) (thin filmtransistor) array can reach the purpose that shows the different color image.

Consult Fig. 1, be a kind of floor map of prior art colored filter.This colored filter is made up of the pixel of a plurality of orderly arrangements, and each pixel is made up of R (red), G (green), three sub-pixels of B (indigo plant).This arrangement mode is simple in structure, be easy to make, but shortcoming is: as suppose a rectangular area, its length is identical with the length and the width of a width and a pixel, then each sub-pixel all concentrates in this rectangular area in each pixel of the colored filter of this structure, therefore, cause the colour mixture inequality easily, colored display effect is bad.

No. 5144288 patent of United States Patent (USP) provides a sub pixel triangularity structure arranged, in each pixel of the colored filter of this structure, have at least a sub-pixel not divide fully to be comprised and be trapped among in the rectangular area that epimere supposes, same in other words sub-pixel can be comprised in simultaneously at least two suppose in the zone that so the colour mixture effect is arranged and will be got well with respect to linear pattern shown in Figure 1.

Consult Fig. 2, No. 5216414 patent of United States Patent (USP) provides a sub pixel to become the structure of mosaic arrangement, though in each pixel of the colored filter of this structure each sub-pixel still all concentrate on one suppose in the zone, but sub-pixel has formed dislocation between its neighbor, has therefore also strengthened the colour mixture effect.

In addition, in the middle of above-mentioned given example, also exist a problem: promptly because the pixel of its colored filter and sub-pixel thereof are the arrangements of rectangular node shape, therefore when LCD need show oblique image, the sawtooth of image border can be apparent in view, when especially the image border contrast is stronger.

Summary of the invention

In view of above-mentioned deficiency, fundamental purpose of the present invention is to provide a kind of colored display effect good, during simultaneously oblique display image, and the colored filter of the sawtooth of the image border of can weakening.

The objective of the invention is to be achieved through the following technical solutions:

The invention provides a kind of colored filter, be provided with a transparency carrier, on this substrate, be formed with shading region, also be distributed with plurality of pixels simultaneously, wherein each pixel is equipped with first color zones, second color zones, the 3rd color zones, especially described each first color zones, second color zones, the 3rd color zones all are a centrosymmetric hexagon, on this transparency carrier, be the center simultaneously, be honeybee around it and put down second color zones, the 3rd color zones that shape ground is rabbeted six spaces with any one first color zones.

On the said structure basis, wherein:

The grid that hexagonal each limit of described each first color zones, second color zones, the 3rd color zones is formed forms described shading region.

Described shading region is to be formed by chromium or black photosensitive resin.

Described transparency carrier is meant glass substrate or transparent polymer material substrate.

Described first color zones, second color zones, the 3rd color zones are respectively successively corresponding to the color zones of red, green, blue three sub pixels.

Described each first color zones, second color zones, the 3rd color zones all are a regular hexagon.

Compared to prior art, the invention has the advantages that: at first, the color zones among the present invention (being sub-pixel) be regularly arranged, in specific implementation process, have operability; Secondly, each sub-pixel all adopts centrosymmetric hexagon, put down the interlocking of shape ground to be honeybee between each sub-pixel simultaneously, not only realized seamless spliced, and the sub-pixel that is under the jurisdiction of different pixels is embedded into as much as possible mutually in other pixels, promptly each sub-pixel week the embedded different subpixel that is connected to six spaces, therefore, compare prior art neutron pixel distribution and more disperse, have better colour mixture effect; Moreover, because each sub-color zones has adopted centrosymmetric hexagonal design, improved the analog form when showing, therefore when showing oblique image, needed lines can be better simulated at centrosymmetric hexagonal edge, weaken the sawtooth of easy appearance with respect to the rectangle sub-pixel, can improve its visual effect.

Description of drawings

In order to be easy to explanation, the present invention is done to describe in detail by following preferred embodiment and accompanying drawing.

Fig. 1 is the planar structure synoptic diagram that each sub-pixel (or color zones) distributes on the colored filter that liquid crystal indicator is used in the prior art.

Fig. 2 is the planar structure synoptic diagram that each sub-pixel (or color zones) distributes on the colored filter that liquid crystal indicator is used in the another kind of prior art.

Fig. 3 is the planar structure synoptic diagram of each hue distinguishes cloth on a kind of colored filter of the present invention.

Embodiment

See also Fig. 3, a kind of colored filter of the present invention is provided with a transparency carrier 1, and this transparency carrier 1 can adopt glass substrate, also can adopt the transparent polymer material substrate; 1 is formed with the shading region 2 that is formed by chromium or black photosensitive resin on this substrate, also be distributed with plurality of pixels simultaneously, wherein each pixel is equipped with first color zones 3, second color zones 4, the 3rd color zones 5, promptly respectively successively corresponding to the color zones of red (R), green (G), blue (B) three sub pixels; Wherein each first color zones 3, second color zones 4, the 3rd color zones 5 all are a centrosymmetric hexagon (wherein with regular hexagon structure the best, present embodiment is that to connect shapes with positive six be example), on this transparency carrier 1, be the center simultaneously, be honeybee around it and put down second color zones 4, the 3rd color zones 5 that shape ground is rabbeted six spaces with any one first color zones 3.

The grid that above-mentioned shading region 2 is made up of each first color zones 3, second color zones 4, orthohexagonal each limit of the 3rd color zones 5 forms.
