Description
Technical field
The present invention relates to display technology field, more particularly, to a kind of side shading glue and frame-free displaying device.
Background technology
With the development of Display Technique, the plane such as liquid crystal display (Liquid Crystal Display, LCD) display dress
Put because having the advantages that high image quality, power saving, fuselage be thin and applied range, and be widely used in mobile phone, TV, individual number
The various consumption electronic products such as word assistant, digital camera, notebook computer, desk computer, become the master in display device
Stream.
Liquid crystal indicator on existing market is most of to be backlight liquid crystal display, it include display panels and
Backlight module (backlight module).The operation principle of display panels is to put in the middle of the parallel glass substrate of two panels
Put liquid crystal molecule, have many tiny electric wires vertically and horizontally in the middle of two panels glass substrate, to control liquid crystal by whether being energized
Molecular changes direction, the light of backlight module is reflected generation picture.
Generally display panels are by color film (CF, Color Filter) substrate, thin film transistor (TFT) (TFT, Thin Film
Transistor) substrate, the liquid crystal (LC, Liquid Crystal) being sandwiched between color membrane substrates and thin film transistor base plate and close
Sealing frame (Sealant) forms.
As the outstanding person of flat faced display, Thin Film Transistor-LCD (TFT-LCD) due to have low power consumption,
The performance such as excellent picture quality and higher production yield, has already taken up the leading position of display field at present, and,
Continuous innovation with Display Technique and the continuous improvement of display associated materials, Ge great panel factory be also constantly push away old go out
Newly, constantly there is new display miscellaneous to appear on the market, meet consumer from display effect, outward appearance etc. various aspects and regarding
Feel, the demand of the every aspect such as when participating in the cintest experience and outward appearance impression, such as nearly 5 years curved face products hot greatly and fine appearing for nearly 3 years
The Rimless product at angle, all greatly improves the appearance of display, and certain behind thing followed is bigger market
Profit.
So, so-called Rimless (also known as Bezel-less) display, it is different from traditional TFT-LCD display, but
It is not Rimless truly, but will go in the frame of display side in traditional TFT-LCD display module frame
Fall, and by the width of the frame adhesive in constriction face and black matrix" (BM), display area is done greatly further, to sight
For the person's of seeing angle, display has bigger display area and no module frame blocks, so give people a kind of purely, more
The display impression of big viewing area.This slight movement, greatly improves the appearance of display, at present in the industry such
Product is mainly firmly occupied leading by Korea S's Samsung and happy King Company.
The display effect behind of new display must have new Display Technique or material to be supported, and Rimless
Display is no exception, and after removing module frame, because the side of display does not block, thus backlight readily penetrates through
Under produce light leak it is therefore necessary to be solved at the side of (glass) substrate and gap therebetween.Commonly used in the trade at present
Way is that coating one circle has certain adhesive force, resistance to steam, certain light at the side of upper and lower base plate and gap therebetween
The shading glue (side-seal) of density (OD) value, to stop the light leakage phenomena brought because of backlight through glass sides and gap.Should
Class shading glue material is usually ultraviolet light (UV) curing type shading glue material, and main component is acryl resin, light trigger, dye
Material and additive etc., because on processing procedure, such shading glue material needs to meet the requirement of quick-hardening and shaded effect requires,
Therefore light trigger seems most important with the selection of dyestuff.
