Description
Technical field
The present invention relates to a kind of liquid crystal display production method more particularly to a kind of full view TN liquid crystal display producers
Method.
Background technique
Existing common TN liquid crystal display production technology is: upper and lower level glass substrate ITO photoetching COM and SEG figure are used,
COM and SEG figure be whole blocks, surface printing PI liquid insulating layer, with 260 degree of high temperature bakings 90 minutes, again to solidification after
PI liquid insulating layer is rubbed, is fitted to together by upper lower glass substrate ITO, and sylphon is made, pours into liquid crystal wherein, COM
It is Chong Die up and down with SEG figure, so that liquid crystal ion is distorted by electric current, forms liquid crystal display and come out.
The shortcomings that prior art, is: COM and SEG figure be whole blocks, surface PI liquid insulating layer printing solidification after rub
So that liquid crystal is all carried out proper alignment according to frictional direction, cause opposite direction visual angle occur 15-20 degree without display effect phenomenon,
Or be displayed without and, there is display blind area.
In order to eliminate anti-visual angle blind zone, also has and attempt to develop TN full view technology.Existing TN full view technology is: including
The COM electrode of photoetching strip on the inside of the upper ITO layer of top glass substrate, photoetching is long on the inside of the lower ITO layer of lower glass substrate
The SEG electrode of bar shaped, and be equipped in the COM electrode several the first engraved structures (parallel hollow out, line width line-spacing be 50u ×
15u), several the second engraved structures are equipped in SEG electrode (parallel hollow out, line width line-spacing are 50u × 15u)；Under COM electrode
PI insulating layer on surface printing, the PI insulating layer under the printing of SEG electrode top；Top glass substrate and lower glass substrate are passed through
Frame glue and gap powder be fixed to constitute glass liquid crystal cell, the COM electrode and SEG electrode is orthogonal overlaps, and in COM electrode
The second engraved structure in first engraved structure and SEG electrode is in parallel spaced-apart away from arrangement.
Although this TN full view technology eliminates anti-visual angle blind zone to a certain degree, the display effect of full view is realized with this
Fruit, still, however it remains two problems: 1, (flat due to being equipped with several first, second engraved structures in COM, SEG electrode
Row hollow out, line width line-spacing are 50u × 15u), the first, second engraved structure is overlapped cannot differ beyond 5um up and down, in this way, making
Make in technique to top and bottom fitting precision prescribed it is high, yields is low in actual production, yield be 70% or so；In addition, it is desirable to make
Production can be realized with import equipment, and cost of equipment is up to 800,000 yuans, high production cost；2, it is set in COM, SEG electrode
There are several the first, second engraved structures, parallel hollow out keeps the opposite variation of the orientation consistency of liquid crystal ion guide very much, with
The contrast that this product for reaching full view is integrally shown can decline 30%, and market prospects are bad.So existing TN full view skill
Art is unable to business application substantially.
How can just find one kind and can eliminate anti-visual angle blind zone, realize that full view is shown, production cost and low TN liquid
Crystal display screen production method is those skilled in the art's technical problem in the urgent need to address.
Summary of the invention
It is an object of the invention in view of the above-mentioned problems of the prior art, providing one kind, can to eliminate anti-visual angle blind
Area realizes that full view is shown, production cost and low TN liquid crystal display production method.
To achieve the goals above, full view TN liquid crystal display production method of the invention includes the following steps:
(1) engraved structure is set in SEG electrode, on the glass substrate ITO of photoetching to SEG electrode surface, the printing of SEG electrode surface
High-intensitive barrier layer；
(2) SEG electrode surface substrate is bonded with COM electrode surface substrate.
The engraved structure, according to display view angle direction and the parallel hollow out of opposite direction, line width is 50 μm, and line-spacing is 15 μm.
After the engraved structure and high-intensitive barrier layer are set, toasts 60 minutes and solidify through 300 DEG C, light penetration is extremely
97%。
Using method of the invention, engraved structure, the glass substrate ITO of photoetching to SEG electrode surface are set in SEG electrode
On, and high-intensitive barrier layer is printed in SEG electrode surface, in this way, anti-visual angle blind zone can be eliminated, realize that full view is shown, gram
Take the defect of the common TN liquid crystal display of the prior art；Meanwhile and overcoming lacking for existing TN full view technology bilayer engraved structure
It falls into, is able to achieve full view and shows, production requirement is simple, and yields is high, and production yield can reach 92% or so, and be not required to
The special process equipment of import is wanted, production cost is low.
Applicant has found when researching and developing technology of the invention by test repeatedly, and hollow out knot is only arranged in SEG electrode
In structure photoetching to the glass substrate ITO of SEG electrode surface, anti-visual angle blind zone can be eliminated to a certain extent, and still, effect is not enough
Ideal, it is more less better than existing TN full view technology bilayer engraved structure；But it is while again high-strength in the printing of SEG electrode surface
It spends after barrier layer, just can solve these problems completely, change liquid crystal ion regularity distortion dispersed arrangement, eliminate anti-
The visual angle blind zone of visual angle 15-20 degree forms full view LCD screen, by printing high-intensitive barrier layer (TOP), reinforces light transmission
Rate and flatness improve product and display contrast, and display effect is good, fully achieve the purpose of the present invention.
Detailed description of the invention
Fig. 1 is liquid-crystal displaying screen structure schematic diagram of the present invention.
Specific embodiment
Illustrate technical solution of the present invention With reference to embodiment.
TN liquid crystal display production method of the invention includes the following steps:
(1) engraved structure 2 is set in SEG electrode, on the glass substrate ITO of photoetching to SEG electrode surface, SEG electrode surface print
Brush high-intensitive barrier layer 1；
(2) SEG electrode surface substrate is bonded with COM electrode surface substrate.
Engraved structure, according to display view angle direction and the parallel hollow out of opposite direction, line width is 50 μm, and line-spacing is 15 μm.This is
Preferred plan.
After engraved structure and high-intensitive barrier layer are set, toasts 60 minutes and solidify through 300 DEG C, light penetration to 97%.
This is preferred plan.
SEG electrode surface prints high-intensitive barrier layer, then prints PI insulating layer 3, then be bonded.
Other steps are all the prior arts.
