Abstract
A high-contrast black film liquid crystal display relates to an electronic display screen, in particular to a liquid crystal electronic display screen. The liquid crystal electronic display screen comprises a front ITO glass substrate and a rear ITO glass substrate which are arranged in a front polaroid and a rear polaroid, as well as frame glue and UV glue which are used for sealing the circumference, wherein a front ITO pattern, a rear ITO pattern, a front PI oriented layer and a rear PI oriented layer are respectively arranged between the front ITO glass substrate and the rear ITO glass substrate from outside to inside; a plastic ball is arranged between the front oriented layer and the rear oriented layer; liquid crystal is arranged between the front oriented layer and the rear PI oriented layer; and black film printing ink is arranged between the front ITO pattern and the front PI oriented layer. The utility model has the advantages that the luminousness of the display part is close to the black film, the color is black, the whole display screen is black when not in display, the problem of bad contrast can be well solved, and the contrast is good.
Description
Technical field:
The utility model relates to the electronic display curtain, especially the liquid crystal electron display screen.
Background technology:
Common black film LCDs d* Δ n is about 1.0, is the second minimum display mode, and the transmittance of display part is apparently higher than the black film part, and background color is generally green or blueness, and is bigger with the color distinction of black film itself, causes when showing the contrast end poor.This part causes the effect of similar ghost owing to the printing opacity problem when normally showing, do not reach comparatively ideal effect.
Summary of the invention:
The purpose of this utility model is to provide a kind of high-contrast black film LCDs.
It comprises frame adhesive and the UV glue that forward and backward ito glass substrate in the forward and backward polaroid and sealing are all around used; Ecto-entad is provided with forward and backward ITO pattern and forward and backward PI oriented layer respectively between the forward and backward ito glass substrate; Between the forward and backward PI oriented layer plastic cement ball is set; Between the forward and backward PI oriented layer liquid crystal is set; Black film printing ink is set in the middle of preceding ITO pattern and the preceding PI oriented layer.
The development etching on ito glass substrate of ITO pattern forms.
Plastic cement bulb diameter in the liquid crystal is 9um.
It is 0.25 liquid crystal that liquid crystal is chosen refractive index n.
Its advantage of the utility model is: display part transmittance and black film are approaching, and color is a black, and entire display screen is a black when not showing, the problem of the fine solution poor contrast of energy has good contrast.
Description of drawings:
Accompanying drawing 1 is a right pseudosection of the present utility model.
Embodiment:
Frame adhesive (5) and UV glue (8) that forward and backward ito glass substrate (1) in the forward and backward polaroid (9) and sealing are all around used; Ecto-entad is provided with forward and backward ITO pattern (2) and forward and backward PI oriented layer (4) respectively between the forward and backward ito glass substrate (1); Plastic cement ball (6) is set between the forward and backward PI oriented layer (4); Liquid crystal (7) is set between the forward and backward PI oriented layer (4); Preceding ITO pattern (2) and the middle black film printing ink (3) that is provided with of preceding PI oriented layer (4).ITO pattern (2) is gone up the development etching at ito glass substrate (1) and is formed.Plastic cement ball (6) diameter in the liquid crystal (7) is 9um.It is 0.25 liquid crystal (7) that liquid crystal (7) is chosen refractive index n.
System box technological process:
1. with ito glass substrate (1) development etching, form ITO pattern (2);
2. coat black film printing ink (3);
3. be coated with PI oriented layer (4) on the sheet glass up and down;
4. it is directed to solidify the back friction;
5. print frame adhesive (5), the middle 9um liner plastic cement ball (6) that sprays, applying hot pressing,
The box of making stable 9um thick (d).
Irritating brilliant selects: liquid crystal (7) is irritated in the cutting back, seals with UV glue (8).It is 0.25 liquid crystal that liquid crystal is chosen refractive index (Δ n), makes d* Δ n value be 2.2-2.3 like this, forms the 3rd minimum liquid crystal display pattern.
The polaroid collocation: polaroid (9) is sticked in front and back.For reaching the lower effect of transmittance, select high degree of polarization frosting polaroid (9) for use before and after the LCD, make the whole blackness of no black film part reach the background color approaching, thereby promoted the contrast of whole LCD with the black film blackness.
By liquid crystal (7), box is thick and polaroid collocation reaches the black effect when display part is not lighted, and has increased the contrast of black film product.
Claims (4)
1, a kind of high-contrast black film LCDs, it comprises frame adhesive and the UV glue that forward and backward ito glass substrate in the forward and backward polaroid and sealing are all around used, and it is characterized in that: ecto-entad is provided with forward and backward ITO pattern and forward and backward PI oriented layer respectively between the forward and backward ito glass substrate; Between the forward and backward PI oriented layer plastic cement ball is set; Between the forward and backward PI oriented layer liquid crystal is set; Black film printing ink is set in the middle of preceding ITO pattern and the preceding PI oriented layer.
2, high-contrast black film LCDs as claimed in claim 1 is characterized in that: the development etching on ito glass substrate of ITO pattern forms.
3, high-contrast black film LCDs as claimed in claim 1, it is characterized in that: the plastic cement bulb diameter in the liquid crystal is 9um.
4, as claim 1 or 3 described high-contrast black film LCDs, it is characterized in that: it is 0.25 liquid crystal that liquid crystal is chosen refractive index △ n.
