Description
Technical field
It the utility model is related to a kind of technical field of large size panel, more particularly to a kind of large scale curvature panel.
Background technology
As the fast development of Display Technique is, it is necessary to which panel vendor constantly improves the display performance and product of machine product
Matter, such as LCD technology, LED technology, laser display technology and OLED technology, the application situation of diversification is presented, display is nowhere
Do not exist.For example, Transparence Display has gradually come into daily life from science fiction sheet.It can be as the end of public information display
End, there is provided wide application space, be particularly widely used in digital signage application field, as display window,
Refrigerator doors, vending machine etc..Numerous manufacturers using Samsung as representative release Transparence Display product one after another, are such as used for bullion
Display case, material object is perfectly combined with video content, allows video effect to have more impulsive force, constantly bring induce one into
The image quality experience of victory.Meanwhile with reference to projecting type capacitor touch technology, can also meet can Transparence Display and human-computer interaction intelligence
Change functional requirement.Through this " intelligentized updating " product, passenger is while glass rear is seen, moreover it is possible to is shown on screen
Various images, text information, product interest and convenience are added, brings strong visual impact.
For Transparence Display touch-control product, mainly include three parts, respectively cover-plate glass, touch screen and display screen.
Wherein, cover-plate glass is typically by the rigid glass material of tempering processing, and transmitance is more than 90%；Touch screen is touched with projection-type
Control screen is main flow, and its substrate is generally the plastic material of soft flexible, and in the conduction electricity for making x directions and y directions thereon
Pole, transmitance is more than 80%；And display screen is generally common rigid alkali-free glass substrate, it is made up of two glass gluings,
Its transmitance is more than 30%.
For display screen technology, LCD technology needs external light source or to backlight, the design of panel, but its transmitance is low,
It is difficult to play penetrating display effect；And shadow casting technique uses the glass of half-reflection and half-transmission, but large scale projecting apparatus limits application
Scene；Integrated comparative, OLED technology can provide optimal Transparence Display effect, and attention.Transparent OLED is saturating with other
Substantially show and compare, for its transmitance more than 40%, brightness reaches 150nits, and colour gamut belongs to OLED and show skill more than 100%NTSC
A kind of brand-new application of art, there are many difficult needs to overcome in the cruel application environment of track traffic.This gives track traffic
How application proposes huge challenge for glass manufacturer.
It is still the fitting side that touch screen is shown with reference to small-medium size in the industry at present in addition, for large scale attaching process
Method, such as using OCA the or OCR materials technique that fitting or frame paste entirely, but the full attaching process of large scale has air blister defect, micronic dust
Defect etc., yield is relatively low, and frame patch technique reduces the display effect of display screen because touch screen and display screen have space.
On large scale attaching process, it is only capable of in the industry realizing that plane is bonded at present, for having curvature, hyperbolicity and the fitting of three dimensional curvature
It is helpless.

Second organic glue-line 13 of layer 11 is adhered to glass cover-plate 10, and the touch-control that substrate material is PET is avoided thus by said structure
Adhesiveness between the organic 11 and second organic glue-line 13 of glue-line of panel 12 and first is bad, and then improves contact panel 12 and glass
The fitting adhesiveness of cover plate 10, in other words, on the binding face of contact panel 12 do not have to set OCA colloids to fit in glass yet
On cover plate 10.Distance between glass cover-plate 10 and contact panel 12 is more than 0.1mm, and it is mainly adjusted by first organic glue-line 11
Thickness and adjust, so the thickness of first organic glue-line 11 is more than 0.1mm.
Distance between OLED display panel 14 and contact panel 12 is more than 0.1mm, and it is mainly adjusted by the second organic gel
Layer 13 thickness and adjust, so the thickness of second organic glue-line 13 is more than 0.1mm.The area of 3rd organic glue-line 15 is more than the
The area of two organic glue-lines 13, also illustrate that the area of the 3rd organic glue-line 15 also greater than the area of first organic glue-line 11, exceedes
The part of 3rd organic glue-line 15 of second organic glue-line 13 is attached at the first organic glue-line 11 and glass cover-plate 10, with fixation
OLED display panel 14 is in glass cover-plate 10.In addition the large size panel 1 with glass cover-plate 10 of present embodiment further includes
Protective layer 16, protective layer 16 are attached at the 3rd organic glue-line 15, the transmitance of raising large size panel 1, wherein protective layer 16
Material is plastic cement or glass, plastic cement such as PET.
The preparation method of the large size panel 1 with glass cover-plate 10 of present embodiment is first with isopropanol or anhydrous
Alcohol washes glass cover-plate 10；The organic glue-line 11 of now first, 12 and second organic glue-line 13 of contact panel, OLED display panel
14 and protective layer 15 be sequentially attached at glass cover-plate 10；Again by the glass cover-plate 10 attached, first organic glue-line 11, touch surface
Plate 12, second organic glue-line 13, OLED display panel 14 and protective layer 15 are sent into autoclave and are bonded, to autoclave before fitting
Cold to vacuumize, cold to find time more than 2 hours, vacuum is between -0.05MPa and -0.1MPa.When the glass cover-plate attached
10th, first organic glue-line 11, contact panel 12, second organic glue-line 13, OLED display panel 14 and protective layer 15 are in autoclave
When being inside bonded, the pressure of autoclave is maintained between 0KPa and 800KPa, and its binding temperature is Celsius with 90 between 50 degrees Celsius
Between degree, after pressure and the binding temperature of autoclave are constant, kept for the time of constant binding temperature small with 12 between 0.5 hour
Time.
