Abstract
A method for manufacturing a high-duty cycle vertical orientation liquid crystal display device comprises a preceding step of forming patterns on glass substrates, a middle step of coating the substrates with an orientation liquid and carrying out orientated friction, and a final step of manufacturing a glass box, injecting liquid crystals, and manufacturing a liquid crystal display screen, wherein in the middle step, the glass substrate is coated with the orientation liquid; the glass substrate coated with the orientation liquid is baked and cured in a low-temperature environment of 60-120 DEG C; and orientated friction is performed on one of a pair of glass substrates for forming the glass box. The vertical orientation liquid crystal display device manufactured using the method of the invention may achieve high-channel number digital driving, namely, the duty cycle of the liquid crystal display may be 1-1/128 duty. The method for manufacturing the high-duty cycle vertical orientation liquid crystal display device has the advantages of high contrast ratio, full-visual angle without dead zone, high response speed, high definition, and the like.
Description
Technical field
The present invention relates to liquid crystal display manufacturing technology, particularly to orientation from high duty ratio vertical row to liquid crystal display
Friction process manufacturing technology.
Background technology
Vertical row has the features such as contrast height, visual angle width to liquid crystal display (va-lcd), only in field of liquid crystal display
Set a flag.Products application scope is wide, the such as application such as vehicle-mounted product, household appliances, intelligence wearing.Existing at present (va-lcd) produces
Product are low duty ratio (1/8duty and following) liquid crystal displays, drive way relatively low.In low duty ratio, as 1/2,1/4duty
Using just embodying that contrast is high, visual angle width the features such as, therefore more applicable fields type liquid crystal displays at present.Existing vertical
Arrange and be only applicable to the low display driving under the conditions of way to liquid crystal display (va-lcd) manufacturing technology, e.g., dutycycle is 1/2,
1/4 or 1/8duti etc., it is only able to display short in size numeral (8 word), purposes is limited.When requiring display content more, such as dutycycle exists
, to liquid crystal display, the product that prior art is made is it may appear that contrast reduces, intersects effect for 1/16duti and above vertical row
Substantially should diminish with angular field of view, have the defects such as blind area during display, liquid crystal display can not normally show figure.
Content of the invention
The present invention provides a kind of high accounting vertical row to the manufacture method of liquid crystal display screen, using the new process of rubbing, carries
The contrast of high display, solves angular field of view in prior art and diminishes, have the technical problem of blind area during display.
The new technology that the present invention provides for solving above-mentioned technical problem comprises the following steps: a. makes on the glass substrate
Make the front operation of image；B. coat the middle operation of oriented liquid and rubbing on the glass substrate；C. make glass cartridge,
Perfusion liquid crystal and the rear operation making LCDs；Described in step b, middle operation comprises the following steps: b1. is in glass
Oriented liquid is coated on substrate；B2. it is coated with the glass substrate of oriented liquid baking-curing under 60～120 DEG C of low temperature environment；
B3. a piece of glass substrate making in a pair of glass substrate of glass cartridge is selected to be oriented friction.
The vertical row that the present invention makes can be realized high way number to liquid crystal display and drive, i.e. the duty of liquid crystal display
Ratio can accomplish 1-1/128duty.It has the advantages that than spend high, full visual angle non-blind area, response speed faster, high definition.
Under 1/96duti drive condition, vertical row can be accomplished to the technical parameter of liquid crystal display: 160 ° of angular field of view: ＞；During response
Between: ton:120ms；toff:20ms；Contrast: 800.
Specific embodiment
The specific embodiment of the present invention is presented herein below.
This high duty ratio vertical row comprises the following steps to the manufacture method of liquid crystal display: a. is on the glass substrate
Make the front operation of image；B. coat the middle operation of oriented liquid and rubbing on the glass substrate；C. make glass case
Body, irrigate liquid crystal and the rear operation making LCDs；And described middle operation comprises the following steps in stepb: b1.
Coat oriented liquid on the glass substrate；B2. the glass substrate being coated with oriented liquid dries under 60～120 DEG C of low temperature environment
Roasting solidification；B3. a piece of glass substrate making in a pair of glass substrate of glass cartridge is selected to be oriented friction.
In step b2 of the present invention, the preferred version of solidification temperature is at 80～110 DEG C, and preferred solidification temperature is 90
～100 DEG C.
Above content is to further describe it is impossible to assert with reference to specific preferred implementation is made for the present invention
Being embodied as of the present invention is confined to these explanations.For general technical staff of the technical field of the invention,
On the premise of present inventive concept, some simple deduction or replace can also be made, all should be considered as belonging to the present invention's
Protection domain.
