Description
Technical field
The utility model is related to VA display technologies fields, and in particular to the VA displays of black hollow out.
Background technology
There are many type of liquid crystal display, wherein, twisted nematic liquid crystal display（That is Twist Nematic Liquid
Crystal Display, abbreviation TN-LCD）Mainly display is realized using the rotation effect of liquid crystal molecule, due to TN-LCD's
The steepness of electroluminescent distortion curve is not high, therefore is difficult to apply to the display of high contrast.With the improvement of living standards and science
The development of technology, consumer are higher and higher to the liquid crystal display requirement of the products such as electronic product or home appliance.Such as to liquid crystal
The requirement of display screen indication range is more and more wider.Therefore, VA liquid crystal displays obtain consumer since its visible angle is big
Favor.In the prior art, when display screen strabismus is seen, contrast is not high.
Utility model content
For the defects in the prior art, the utility model provides a kind of VA displays of black hollow out, can solution by no means
The problem of displaying block strabismus more blackens when seeing.
A kind of VA displays of black hollow out provided by the utility model, including set gradually upper strata polaroid, upper strata
Substrate, liquid crystal layer, upper strata circuit layer, black light-blocking film, lower circuit layer, underlying substrate and lower floor's polaroid, black light-blocking film
It is arranged on the upper epidermis of lower circuit layer；Black light-blocking film is engraved structure.
Further, black light-blocking film includes hollow-out part and entity part, and hollow-out part is display area, entity part
For non-display area, the content word shape that hollow out shape and the display screen of hollow-out part are shown is consistent.
Further, liquid crystal layer is VA negative liquid crystal layers.
Further, upper strata polaroid and lower floor's polaroid are VA polaroids.
Further, it is fixed between top substrate layer outer and underlying substrate outer surrounding by black fluid sealant adhesion, structure
Into a seal cavity, the outer edge of black fluid sealant and top substrate layer contact surface there are gap, the black fluid sealant with
There are gap, the gaps to be completely covered by by edge black film for the outer edge of underlying substrate contact surface.
Further, the side of underlying substrate is provided with circuit electrode.
As shown from the above technical solution, the beneficial effects of the utility model：
The utility model provides a kind of VA displays of black hollow out, including upper strata polaroid, the upper strata base set gradually
Plate, liquid crystal layer, upper strata circuit layer, black light-blocking film, lower circuit layer, underlying substrate and lower floor's polaroid；Black light-blocking film is set
Put the upper epidermis in lower circuit layer.Black light-blocking film is engraved structure.Black light-blocking film includes hollow-out part and entity part,
Hollow-out part is display area, and entity part is non-display area, the content that hollow out shape and the display screen of hollow-out part are shown
Word shape is consistent.Display area is brighter, and non-display area is more impermeable, improves the contrast of display screen.
Description of the drawings
It, below will be right in order to illustrate more clearly of specific embodiment of the present invention or technical solution of the prior art
Specific embodiment or attached drawing needed to be used in the description of the prior art are briefly described.In all the appended drawings, it is similar
Element or part are generally identified by similar reference numeral.In attached drawing, each element or part might not be according to practical ratios
It draws.
Fig. 1 is a kind of sectional view of the VA displays of black hollow out of the utility model.
Fig. 2 is the structure diagram of black light-blocking film in a kind of VA displays of black hollow out of the utility model.
Specific embodiment
The embodiment of technical solutions of the utility model is described in detail below in conjunction with attached drawing.Following embodiment is only
For clearly illustrating the technical solution of the utility model, therefore example is only used as, and cannot this practicality be limited with this
Novel protection domain.
It should be noted that unless otherwise indicated, technical term or scientific terminology used in this application should be this reality
The ordinary meaning understood with novel one of ordinary skill in the art.
It please refers to Fig.1 to Fig. 2, a kind of VA displays of black hollow out provided in this embodiment are upper including what is set gradually
Layer polaroid 1, top substrate layer 2, liquid crystal layer 3, upper strata circuit layer 4, black light-blocking film 5, lower circuit layer 6, underlying substrate 7 and under
Layer polaroid 8；Black light-blocking film 4 is arranged on the upper epidermis of lower circuit layer 6, and black light-blocking film 5 is engraved structure.Black shading
Film 5 includes hollow-out part 51 and entity part 51, and hollow-out part 51 is display area, and entity part 52 is non-display area, is engraved
The hollow out shape of empty part 51 is consistent with the content word shape that display screen is shown.According to display by not identical text to be shown
Word, the shape of hollow-out part are different.Display area is brighter, and non-display area is more impermeable, improves the contrast of display screen.
Liquid crystal layer 3 is VA negative liquid crystal layers.Upper strata polaroid 1 and lower floor's polaroid 8 are VA polaroids.
It is fixed between 7 outer surrounding of 2 outer of top substrate layer and underlying substrate by 9 adhesion of black fluid sealant, forms one
There are gap, black fluid sealant 9 and underlying substrates for the outer edge of seal cavity, black fluid sealant 9 and top substrate layer contact surface
There are gap, gaps to be completely covered by by edge black film 10 for the outer edge of contact surface.It can solve under the prior art because of silk-screen
The insurmountable edge strabismus leakage problem of black ink.Further improve the contrast of display screen.
