Description
Technical field
The invention belongs to display technology field, and in particular to a kind of black matrix structure, mask plate, color membrane substrates and display dress
Put.
Background technology
At present, liquid crystal display (Liquid Crystal Display：Abbreviation LCD) with its excellent performance and maturation
Technology becomes the main product on market.Along with the development of Display Technique, high permeability, large scale low-power consumption, low cost are
Become the developing direction in future display field.
In the preparation process of the color membrane substrates of the liquid crystal display of existing oversize, because substrate size it is larger, it is impossible to
Realize that single exposure forms whole fundamental figure, the exposure technology of whole substrate is realized so as to have to using connecting method.
Under traditional splicing Exposure mode, as the splicing process on splice region both sides is not once to complete, splice region is necessarily caused
Pattern is had differences with the figure of non-splice region.With reference to Fig. 1 and Fig. 2, especially by the black matrix that splicing Exposure mode is formed
Figure, also just say black matrix structure by the pixel unit array that constitutes of splicing of sub- black matrix 100, wherein, each pixel list
Unit 10 includes pixel openings area 11 and surrounds the black matrix pattern area 12 in pixel openings area 11, and two sub- black matrix 100 are spliced to form
Splicing line 20 be located at two row pixel cells 10 pixel openings area 11 between black matrix pattern area 12 at it is in alignment, such as
Shown in Fig. 1；Or be located at through certain string pixel openings area 11, it is in alignment, as shown in Fig. 2 due to sub- black matrix 100
Stitching position certainly exists inevitable error, so that the width in the black matrix pattern area 12 of 20 region of splicing line
The width a in the black matrix pattern area 12 between B and the pixel openings area 11 of two adjacent column pixel cells is different, or is spliced
Pixel openings area 11 width d it is different from the width c in the pixel openings area 11 for not having to splice, and stitching position concentrates on one
On straight line, therefore produce bad position and concentrate point-blank, and then cause to show bad, serious impact picture quality.

So this two row pixel cell produce it is bad draw a straight line a little on, thus will have a strong impact in display aobvious
Show quality.And the splicing line of the square wave, be dispersed between three adjacent row pixel cells, wherein two adjacent column pixel cells it
Between due to splicing produce it is bad be equivalent to a point, the stitching position of this three row pixel cell produces the point of bad formation
Link together as a curve, while these bad points are not concentrated on a line yet, but it is scattered, therefore aobvious
Large effect will not be caused to the quality for showing when showing.Even if in the same manner when the part in splicing line is located at pixel openings area,
Be also what is be dispersed due to splicing the bad of bad student, therefore be also large effect will not to be caused to display quality.
Preferably, the splicing line is located at the black matrix pattern area.
It may further be preferable that the splicing line includes the multiple bending units for linking together, each described bending is single

Height of the maximum height more than the black matrix pattern area 12 described in two adjacent lines between pixel openings area 11.
The splicing line 20 that two sub- black matrix 100 in the black matrix structure of the present embodiment are spliced to form is curve, therefore can be with
Prior art is avoided to concentrate the display for point-blank, causing bad due to splicing line 20.Specifically, with splicing line 20 as position
In the square wave in black matrix pattern area 12, and the width on the line direction of the bending unit of the square wave is the width of pixel cell 10
Degree, the height of column direction be two row pixel cells 10 height as a example by illustrate, in prior art, splicing line 20 is positioned at black
During the straight line in matrix pattern area 12, due to the error of the splicing of sub- black matrix 100, it will have influence on located at adjacent with the splicing line 20
The size of the pixel cells 10 of two row, in other words, the adjacent pixel cell 10 of each two in this two row pixel cell 10 is being spelled
20 position of wiring cause it is bad be equivalent to a point, so this two row pixel cell 10 produce bad be linked to be a little one
On bar straight line, thus display quality will be had a strong impact on when showing.And the splicing line 20 of the square wave, it is dispersed in adjacent three
Between row pixel cell 10, wherein bad being equivalent to one due to what splicing was produced between two adjacent column pixel cells 10
Point, the stitching position of this three row pixel cell 10 produce the point of bad formation and link together as a curve, while these are not
Good point is not concentrated on a line yet, but scattered, therefore will not cause larger to the quality for showing when showing
Affect.Even if in the same manner when the part in splicing line 20 is located at pixel openings area 11, being also to be divided due to splicing the bad of bad student
Scatter, therefore be also large effect will not to be caused to display quality.

The height sum of unit 10, if regarding a point as bad with the display of two adjacent pixel cells 10 of stitching position, now
Multiple points are distributed to the stitching position in three row pixel cells 10, and positioned between points more sparse of same row, because
This will not be impacted to display quality.In the same manner, as shown in figure 4, splicing line 20 is located at the black matrix figure of four row pixel cells 10
As area, i.e. each bending unit Breadth Maximum in the row direction are equal to the width of 2 pixel cells 10, in row side
Height upwards be equal to 3 pixel cells 10 height sum, if with two adjacent pixel cells 10 of stitching position
Display it is bad regard a point as, be now not only located at same row between points more sparse, and point in the row direction
It is also more sparse between point, therefore equally will not be to impacting to display quality.
As another kind of optimal way of the present embodiment, the splicing that the sub- black matrix 100 of the black matrix structure is spliced to form
Line 20 is positioned at pixel openings area 11.The splicing principle of this kind of connecting method is to be located at black matrix pattern area 12 with splicing line 20
Identical, is not described here in detail.
Preferably, the bending unit in the present embodiment can be with square wave, sawtooth waveforms, sine wave, due to the figure of these three
It is more regular and regular, therefore be stitched together and be relatively easy to, other figures are also feasible certainly.
