Abstract
The utility model provides a positive-display type VA (vertical alignment) liquid crystal screen, and relates to an electronic display screen, in particular to an electronic liquid crystal display screen. The positive-display type VA liquid crystal screen comprises a front ITO (indium tin oxide) glass substrate (1), a rear ITO glass substrate (1), border adhesives (5) and UV (ultraviolet) adhesives (8), wherein the border adhesives (5) is used for sealing the periphery. Front and rear ITO patterns (2) and front and rear PI (polyimide) directional layers (4) are respectively arranged between the front and rear ITO glass substrates (1) from the outside to the inside. Liquid crystals (7) are arranged between the front and rear PI directional layers (4). Plastic balls (6) are arranged in the liquid crystals (7), and a polarizer (3) is arranged on the surface of one of the front and rear ITO glass substrates (1). The PI directional layers (4) are made of VA PI materials. The liquid crystals (7) are made of dyestuff type negative liquid crystal materials. The front and rear ITO glass substrates (1) can be made of conductive PET (polyethylene glycol terephthalate) films. The liquid crystals (7) can be dyestuff liquid crystals (7) different in colors. By the aid of the single polarizer, material and labor cost is reduced. Meanwhile, the positive-display type VA liquid crystal screen has the advantages of high contrast and wide visual angle and the like in display.
Description
Technical field
The utility model relates to electronic display screen, especially liquid crystal electron display screen.
Background technology
[0002] when existing VA type LCDs positivity shows, contrast is very poor, only can under negativity show state, just can reach higher contrast.And LCDs is all used upper and lower two-layer polaroid normally to show, therefore material cost and cost of labor are higher.
Summary of the invention
The purpose of this utility model is to provide a kind of display comparison degree high, has the positive phenotype LCDs of VA of extremely wide angle of visibility.
It comprises frame adhesive (5) and the UV glue (8) that forward and backward ito glass substrate (1) and surrounding sealing are used; Between forward and backward ito glass substrate (1), ecto-entad arranges respectively forward and backward ITO pattern (2) and forward and backward PI oriented layer (4); Liquid crystal (7) is set between forward and backward PI oriented layer (4); Plastic ball (6) is set in liquid crystal (7); Before or after one of them surface of ito glass substrate (1) polaroid (3) is set.
PI oriented layer (4) adopts vertical orientated PI material.
Liquid crystal (7) adopts dye-type negative liquid crystal material.
Forward and backward ito glass substrate (1) can adopt the conducting PET film.
Liquid crystal (7) can adopt the dye liquid crystal (7) of different colours.
Its advantage of the utility model is: use monolayer polarizing sheet, reduce material and cost of labor, display comparison degree is high simultaneously, has extremely wide angle of visibility.
Brief description of the drawings:
Accompanying drawing 1 is right pseudosection of the present utility model.
Embodiment:
It comprises frame adhesive (5) and the UV glue (8) that forward and backward ito glass substrate (1) and surrounding sealing are used; Between forward and backward ito glass substrate (1), ecto-entad arranges respectively forward and backward ITO pattern (2) and forward and backward PI oriented layer (4); Liquid crystal (7) is set between forward and backward PI oriented layer (4); Plastic ball (6) is set in liquid crystal (7); Before or after one of them surface of ito glass substrate (1) polaroid (3) is set.PI oriented layer (4) adopts vertical orientated PI material.Liquid crystal (7) adopts dye-type negative liquid crystal material.Forward and backward ito glass substrate (1) can adopt the conducting PET film.Liquid crystal (7) can adopt the dye liquid crystal (7) of different colours as required.
Box technological process processed:
1. by ito glass substrate (1) development etching, form ITO pattern (2);
2. be coated with vertical orientated PI oriented layer (4) at upper and lower ito glass substrate (1);
3. after solidifying, friction is directed;
5. printing frame adhesive (5), the middle liner plastic ball (6) that sprays, laminating hot pressing, makes stable box thick.
Irrigation crystal is selected: after cutting, fill with liquid crystal (7), with UV glue (8) sealing.Liquid crystal (7) is chosen dye-type negative liquid crystal (7).
Polaroid collocation: the one side of front or rear ito glass substrate (1) is sticked polaroid (3).
By using dye-type negative liquid crystal (7), only needing monolayer polarizing sheet to make VA LCDs realize positivity demonstration, can reach high-contrast effect simultaneously.
