Abstract

The present invention discloses a color filter structure which is provided with a transparent baseplate; a plurality of pixels are formed on the baseplate, wherein, each pixel is provided with a first color zone, a second color zone and a third color zone, in particular each pixel is an isosceles trapezoid; each two pixels are spliced to a regular hexagon; three identical regular triangles are in rabbet joint inside each isosceles trapezoid; three regular triangles respectively correspond to the first color zone, the second color zone and the third color zone, and after each two pixels are spliced to the regular hexagon on the transparent baseplate, with an arbitrary regular hexagon as the center, six regular hexagons spliced by other pixels in two 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 colorful filter structure

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 colorful filter structure 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 colorful filter structure, be provided with a transparency carrier, on this substrate, be formed with plurality of pixels, wherein each pixel is equipped with first color zones, second color zones, the 3rd color zones, especially it is trapezoidal that each pixel is isosceles, and be a regular hexagon after per two pixels splicing, at terraced embedded three equilateral triangles that size is identical that are connected to of each described isosceles, these three equilateral triangle districts correspond to this first color zones respectively, second color zones, the 3rd color zones, simultaneously on this transparency carrier, after described pixel two two is spliced into regular hexagon, with any regular hexagon is the center, around it be honeybee put down the interlocking of shape ground have six by the back formed regular hexagon of other pixel two two splicings.

On the said structure basis, wherein:

The grid that each limit of the equilateral triangle 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 fine, green, blue three sub pixels.

Compared to prior art, the invention has the advantages that: at first, be regularly arranged after being a regular hexagon after per two pixels splicing among the present invention, in specific implementation process, have operability; Secondly, each color zones (being sub-pixel) all adopts equilateral triangle, 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 in other pixels as much as possible mutually, therefore, compare prior art neutron pixel distribution and more disperse, have better colour mixture effect; Moreover, because each sub-color zones has adopted the equilateral triangle design, be a regular hexagon after simultaneously per two pixels splicing, therefore improved the analog form when showing, therefore when showing oblique image, the present invention can better simulate needed lines, compared to rectangle sub-pixel of the prior art, weakened the sawtooth of easy appearance greatly, so 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 colorful filter structure of the present invention.

Embodiment

See also Fig. 3, a kind of colorful filter structure 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; It is trapezoidal that wherein each pixel is isosceles, and be a regular hexagon after per two pixels splicing, at terraced embedded three equilateral triangles that area is all identical that are connected to of each described isosceles, these three equilateral triangle districts correspond to this first color zones 3, second color zones 4, the 3rd color zones 5 respectively, simultaneously on this transparency carrier 1, after described pixel two two is spliced into regular hexagon, and be the center with any one regular hexagon that is spliced to form, around it be honeybee put down the interlocking of shape ground have six by the back formed regular hexagon of other pixel two two splicings.

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