Abstract
The embodiment of the invention discloses a display screen which comprises a display plate and a glass plate. The glass plate is arranged on the outer side of the front surface of the display plate and used for protecting the display plate. The display screen also comprises an optical film which is arranged between the display plate and the glass plate, autoclaved and connected with the display plate and the glass plate in a sealing way. Due to the technical means that the optical film is laminated between the display plate and the glass plate and autoclave, the display plate and the glass plate can be fully adhered and sealed to bear the tension of more than MPa/cm<2>. The display screen has the characteristics of fogging and dust prevention, high optical performance and impact resistance.
Description
Technical field
The present invention relates to envelope screen technical field, relate in particular to a kind of display screen and processing technology thereof.
Background technology
Envelope screen technology adopts injection method filling liquid UV glue between glass protection screen and liquid crystal display more at present, then with UV light, it is carried out to photocuring, but in actual process, has following problem:
1, UV glue very easily produces bubble, when envelope screen, cannot cause scrappage higher removal of bubbles, when when the larger specification of processing (as 10 cun) is above, cannot process at all;
2, because UV glue itself has shrinkage factor, when in the larger specification of processing, limit portion can produce contracting glue phenomenon, causes product processing without non-defective unit.
Thereby prior art can not meet need of production and the quality requirements of the especially large specification display screens product of display products.
Summary of the invention
Embodiment of the present invention technical matters to be solved is, a kind of display screen and processing technology thereof that meets need of production and the quality requirements of the especially large specification display screens product of display products is provided.
In order to solve the problems of the technologies described above; the embodiment of the present invention has proposed a kind of display screen; described display screen comprises display board and is located at display board front outside with the glass plate of protection display board, and described display screen also comprises and being arranged between display board and glass plate and through hot-pressing processing and the optical film of be tightly connected display board and glass plate.
Further, optical film thickness is 0.1mm～1.5mm.
Further, display screen also comprises the housing of accommodating fixing described display board, between housing and display board, is provided with backlight.
Further, backlight consists of a plurality of LED luminescence units.
Further, display board is LCD panel.
Correspondingly, the embodiment of the present invention also provides a kind of display screen processing technology, and described processing technology comprises: superimposed step: display board, optical film and glass plate are stacked gradually into compoboard; Heat-press step: compoboard is carried out under predetermined temperature and predetermined pressure to hot-pressing processing.
Further, after described heat-press step, also comprise: cooling step: to the cooling schedule time of the compoboard after hot-pressing processing.
Further, described predetermined temperature is 50 ℃～120 ℃.
Further, described predetermined pressure is 49N～98N.
Further, the described schedule time is 2h～5h.
The display screen of the embodiment of the present invention and the beneficial effect of processing technology thereof are: by adopting between display board and glass plate stacked setting and carrying out the technological means of hot-pressing processing optical film, thereby make complete gluing, sealing between display board and glass plate, and can bearing tension reach 0.8 MPa/more than square centimeter, display screen have do not haze, prevent dust, optical property is higher, the characteristic such as shock-resistant.
Accompanying drawing explanation
Fig. 1 is the structural representation of the display screen of the embodiment of the present invention.
Embodiment
Please refer to Fig. 1, the embodiment of the present invention provides a kind of display screen and processing technology thereof, and display screen comprises housing 10, backlight 20, display board 30, optical film 40 and glass plate 50.Wherein, glass plate 50 is located at the positive outside of display board 30 with protection display board 30, and optical film 40 is arranged between display board 30 and glass plate 50 and through hot-pressing processing and be tightly connected display board 30 and glass plate 50.
Housing 10 is plastic casing or betal can, is specially the shells corresponding to electronic product such as mobile phone, GPS, computer monitor or televisor.
Backlight 20 is located on the circuit board in housing 10, and backlight 20 consists of a plurality of LED luminescence units.
Display board 30 is accommodating to be fixed in housing 10, and in present embodiment, display board 30 is LCD panel 30.
The side that display board 30 deviates from backlight 20 has stacked gradually optical film 40 and glass plate 50.Optical film 40 is the stacked optical film 40 by hot-pressing processing, and optical film 40 thickness are 0.1mm～1.5mm, such as thickness, are 0.5mm, 1mm, 1.2mm or 1.3mm etc.
The processing technology of the embodiment of the present invention comprises:
Superimposed step: display board 30, optical film 40 and glass plate 50 are stacked gradually into compoboard;
Heat-press step: compoboard is carried out under predetermined temperature and predetermined pressure to hot-pressing processing, wherein, described predetermined temperature is 50 ℃～120 ℃, is preferably 80 ℃, and described predetermined pressure is 49N～98N, is preferably 78.4N.
Cooling step: to the cooling schedule time of the compoboard after hot-pressing processing, wherein, the described schedule time is 2h～5h.Particularly, after compoboard hot-pressing processing, cooling 2h～5h is down to normal temperature, is preferably 3h.
Thereby, the process of heat-press step is, at the temperature of 50 ℃～120 ℃, solid state optics film 40 melts completely, under the pressure of 49N～98N, make can not produce bubble in solid state optics film 40 melting processes simultaneously, after cooling step, between display board 30 and glass plate 50, form a kind of solid gum with high bonding force, high transmission rate again.
In sum, by above processing technology, between display board 30 and glass, with optical film 40, fill, make to bond closely between display board 30 and glass plate 50, seamless, thereby make display products possess following functions:
1, effectively prevent the generation at display screen inner absorption dust and steam (aerosol);
2, optical film 40 thickness are between 0.1mm～1.5mm, have reduced the gap between face glass and display screen, thereby can effectively reduce the integral thickness of display;
3, optical film 40 has higher transmittance, and transmittance reaches more than 98%;
4, the refractive index of optical film 40 is between 1.5-1.6, basically identical with the refractive index of glass, display screen is had high visual;
5, strong shock resistance, through the finished display screen of envelope screen, when being subject to falling ball impact test and accidental impact, glass and optical film 40 form one-piece construction, have greatly improved the elasticity of display screen, thereby have made the more difficult breakage of display screen or cracked, more firm;
6, to have bonding strength high for optical film 40, and shrinkage factor, hardness are lower, are not prone to the phenomenons such as contraction, tomography and variable color.
The above is the specific embodiment of the present invention; it should be pointed out that for those skilled in the art, under the premise without departing from the principles of the invention; can also make some improvements and modifications, these improvements and modifications are also considered as protection scope of the present invention.
