Description

The configuration structure of the colour cell of colored filter

Technical field

The present invention relates to a kind of colored filter (color filter) technology, particularly the configuration structure of a kind of colour cell of colored filter (color element) can be kept high aperture under the design of high-res.

Background technology

Along with the progress of science and technology with information, in order to obtain abundant colors information, (colorfilter CF) is used on colour liquid crystal display device (Liquid Crystal Display), charge coupled cell (Charge Coupled Device) and the scanner video products such as (Scanner) colored filter widely.Frivolous for having, power saving, and LCD that can full-colorization characteristic, comprise STN type (Super Twisted Nematic), TFT type (Thin Film Transistor), the color monitor of mim type (MentalInsulator Metal) must use and contain red (R), green (G), blue (B) trichromatic colored filter, it is red to show that its arbitrary pixel with the monochromatic display matrix of script is divided into three sub-pixels, green, primary colors, be in harmonious proportion by trichromatic ratio again and create various colors, thus colored filter that LCD is presented is beautiful, true to nature, bright-coloured picture also can improve its surcharge.

The primary structure of LCD includes electric crystal array film substrate, colored filter substrate and liquid crystal layer, wherein the manufacture method of colored filter substrate is to scribble to lead meagre R, G, B pigment on glass substrate, and the position of R, G, B pigment must with the accurate contraposition of each pixel on the tft array substrate.Consider based on cost of manufacture and quality, R, G, B color layer production method commonly used include: four kinds of pigment dispersing method, decoration method, print process and electricity work methods etc., because the colored filter of pigment dispersing method manufacturing has high precision and preferred photostability and thermotolerance, and becomes the manufacturing main flow of present TFT type colored filter.In addition, in the colored filter substrate manufacture process in early days, black matrix" (blackmatrix) layer is made in meeting in the gap of the colour cell of colored filter, mainly be intended for lightproof area, in order to covering the TFT element on the tft array substrate, and prevent to produce between the adjacent pixel region light leakage phenomena.In order to reduce the processing procedure cost, the colored filter substrate processing procedure of follow-up developments is no longer made black-matrix layer at present, only makes colored filter on glass substrate, and the overlapping region of colour cell that utilizes colored filter is as lightproof area.

See also Figure 1A, 1B and 1C, it shows the configuration pattern of the redness (R) of known colored filter, green (G) and blue three kinds of colour cells such as (B), include triangle (delta) form shown in mosaic (mosaic) form shown in the strip shown in Figure 1A (strip) form, Figure 1B and Fig. 1 C, wherein the triangular form shown in Fig. 1 C can provide easy driving and best colour mixture effect, therefore is widely used at present in the colored filter design of AV video and audio product.

See also Fig. 2 A and 2B, Fig. 2 A shows the top view of the colour cell of known bar form, and Fig. 2 B is the diagrammatic cross-section along the tangent line 1-1 display color unit of Fig. 2 A.Colored filter 10 includes the colour cell 12 of a plurality of bar form configuration structures, and it is arranged in regular turn by green cell 12G, red units 12R and blue cell 12B institute and forms, and the width of these three colour cell 12G, 12R, 12B is identical.Under the restriction of creating conditions, the periphery of two adjacent colour cells can be overlapping, and become the raised areas 14 that dichromatism pigment piles up, this can make and produce uneven pigment thickness distribution situation on the glass substrate, and have influence on the consistance that electric field intensity and liquid crystal molecule in each pixel region turn to, and then cause problems such as light leak, contrast reduction, colour purity are not good, colour mixture.In addition, consider the influence of bit errors, the scope of raised areas 14 can increase and sacrifice aperture opening ratio (aper ture ratio), and the problem of this low aperture opening ratio can be more remarkable in the LCD of high-res.

Summary of the invention

In view of this, purpose of the present invention just is to provide a kind of configuration structure of colour cell of colored filter, is the width design of adjustment member colour cell, can keep high aperture under the design of high-res.

For reaching above-mentioned purpose, the invention provides a kind of configuration structure of colour cell of colored filter, include a plurality of continuously arranged colour cell groups, wherein each colour cell group is to be arranged in regular turn by first colour cell, second colour cell, the 3rd colour cell and the 4th colour cell institute to form, and this first colour cell, this second colour cell and the 3rd colour cell are three kinds of different colour cells; This second colour cell and the 4th colour cell are with a kind of colour cell and have identical size; And the effective width W of this first colour cell 1, this second colour cell effective width W 2And the effective width W of the 3rd colour cell 3Meet following relationship formula: W 1=AxW 2, A=1.7~2.3 wherein; W 3=BxW 2, B=1.7~2.3 wherein.

For achieving the above object, the invention provides the configuration structure of the colour cell of another kind of colored filter, include a plurality of continuously arranged colour cell groups, wherein each colour cell group is to be formed by first colour cell, second colour cell, the 3rd colour cell, the 4th colour cell and the arrangement in regular turn of multicolored color element institute; This first colour cell, this second colour cell and the 3rd colour cell are three kinds of different colour cells; This second colour cell and the 4th colour cell are with a kind of colour cell and have identical size that the 3rd colour cell and this multicolored color element are with a kind of colour cell and have identical size; The effective width W of this first colour cell 1, this second colour cell effective width W 2And the effective width W of the 3rd colour cell 3Meet following relationship formula: W 1=AxW 2, A=1.7~2.3 wherein; W 1=BxW 3, B=1.7~2.3 wherein.
