Abstract

The invention discloses a perpendicular-aligning LCD with a step width greater than or equal to 2.5 mm. The LCD comprises ITO layers overspread on upper glass and lower glass inside a box body, and ITO layers overspread on an upper step or a lower step, or the upper step and the lower step outside the box body, wherein after exposing and acid embossing, the ITO layers on the step adopt the structure of regular hollow at intervals; ITO filling blocks are arranged on the step at the hollow parts; each ITO filling block is divided into two parts by clearance in the width direction of the step; the width of the rectilinear or broken-line clearance is 0.075-0.10 mm; distance is kept between each the ITO filling block and the adjacent ITO layer, and the minimum interval is 0.05 mm; the width of the step is greater than or equal to 2.5 mm. The LCD avoids friction directional stripes caused by the fact that an electrode on the step is parallel to the friction direction, and is simple to manufacture and good in friction stripe prevention effect.

Description

Step width is more than or equal to the vertical orientation type LCD liquid crystal display of 2.5mm

(1) technical field:

The present invention relates to display device, be specially the vertical orientation type LCD liquid crystal display that a kind of step width is more than or equal to 2.5 (mm).

(2) background technology:

Vertical orientation type (VA) liquid crystal display is applied more and more extensive in LCD display in recent years.

Because liquid crystal molecule when its work is similar to vertical orientated, require frictional direction parallel with positive view directions, be positioned at the upper of positive apparent direction for those steps thus or get out of a predicament or an embarrassing situation or the display of up/down steps, because the ITO layer on conventional step has more regular interval hollow out, there is the situation of uneven, after the orientation that rubs, easily cause box body interior orientation Memorability striped.

How to avoid generation friction striped just to become the problem that VA product design and development personnel wait to solve from structural design or process aspect.

(3) summary of the invention:

For the deficiencies in the prior art, the invention provides the vertical orientation type LCD liquid crystal display that a kind of step width is more than or equal to 2.5 (mm), mainly solve due to the directed box body interior orientation Memorability stripes problem causing of friction.

The step width that can address the above problem is more than or equal to the vertical orientation type LCD liquid crystal display of 2.5 (mm), its technical scheme comprises the ITO layer being covered with on upper glass in box body, lower-glass, box body top bar outward or get out of a predicament or an embarrassing situation or up/down steps on the ITO layer that is covered with, through exposure and harsh after, ITO layer on described step is more regular interval hollow out, difference is that the step of described hollow part is provided with ITO filling block, and described ITO filling block is divided into two parts by the gap of step width direction.

In a kind of situation, described gap is made as folding shape shape (being commonly called as zigzag or kitchen knife form), and gap width is chosen between 0.075mm～0.10mm, and this scheme is that override is considered to use, but is not suitable for the situation that connected mode is zebra bar.

In another kind of situation, described gap is made as linear, and gap width is chosen between 0.075mm～0.10mm, and this design only limits to the situation that connected mode is zebra bar.

For avoiding adjacent two ITO layer (electrode) short circuits, described ITO filling block and adjacent ITO layer keep spacing, and the minimum value of described spacing is 0.05mm.

When length≤the 5.0mm of outermost end ITO filling block, because static content is little, ITO filling block can be cut apart without gap.

Technique scheme is applicable to the liquid crystal display that step width is more than or equal to 2.5mm.

Beneficial effect of the present invention:

Step width of the present invention is more than or equal to the vertical orientation type LCD liquid crystal display of 2.5 (mm) can continue to use existing LCD production technology, easy to make, be easy to realize, production cost is low, the problem that can avoid directional memory striped to produce is a kind of high-quality VA liquid crystal display screen products that can meet consumers' demand.

(5) embodiment:

Below in conjunction with accompanying drawing illustrated embodiment, technical scheme of the present invention is described further.

Step width of the present invention is more than or equal in the box body of vertical orientation type LCD liquid crystal display of 2.5 (mm), on upper glass and lower-glass, be covered with ITO layer as far as possible, box body top bar outward 1 or get out of a predicament or an embarrassing situation 1 or up/down steps 1 on be covered with equally as far as possible ITO layer 2, through exposure and harsh after, ITO layer 2 on described step 1 is more regular interval hollow out, step 1 hollow part that there is no ITO layer is filled to ITO filling block 3, along step 1 length direction, described ITO filling block 3 is spaced apart, in the end positions of the ITO filling block 3 of outermost end in step 1, each ITO filling block 3 is 0.05mm with the minimum value of the spacing 5 of adjacent ITO layer 2, as shown in Figure 1.

Described ITO filling block 3 is divided into two equal portions along the gap 4 of step 1 Width, and the span in described gap 4 is between 0.075mm～0.10mm, as shown in Figure 2 and Figure 3.

In a kind of situation, described gap 4 adopts linear, as shown in Figure 2.

In another kind of situation, described gap 4 adopts folding shape shape (also claiming zigzag or kitchen knife form), as shown in Figure 3.

For the ITO filling block 3 of outermost end, can monoblock when its length (along step 1 length direction)≤5.0mm retain and without cutting apart in gap 4, this ITO filling block 3 is 0.05mm with spacing 5 minimum value of inner side ITO layer 2; As outermost end ITO filling block 3 length >5.0mm, for avoiding the static content of monolithic filling excessive, should adopt linear gap 4 or folding shape shape gap 4 to divide equally is two equal portions, and this ITO filling block 3 is 0.05mm with spacing 5 minimum value of inner side ITO layer 2, as shown in Figure 2 and Figure 3.

Technique scheme is applicable to the liquid crystal display of step width >=2.5mm.

Described embodiment is the most preferred embodiment of explanation technical solution of the present invention; not concrete restriction; do not departing under the prerequisite of technical solution of the present invention principle, the present invention also has various changes and modifications, and described changes and improvements all will fall into the claimed scope of the claims in the present invention.
