Abstract
This invention provides an organic luminous panel with a hydrophobic layer including a transparent base plate, at least an organic luminous element, a protection layer and a hydrophobic layer. The organic luminous element includes a first electrode, at least one organic luminous layer and a second electrode orderly set on the transparent base plate, the protection layer is set on the base plate or the second electrode forming a closed system with the base plate, the first electrode, organic luminous layer and the second electrode are set in the closed system, the hydrophobic layer is formed on the protection layer or outer surface of the closed system for preventing water from entering into the element.
Description
Technical field
The present invention is a kind of organic luminous panel with hydrophobic layer, especially in regard to a kind of utilize silicon fluoride alcoholic compound or class diamond film for main composition as hydrophobic layer material, use and avoid water oxygen to enter in the organic illuminating element.
Background technology
Organic luminous panel (Organic Electroluminescent Panel) with its self-luminous, no visual angle, power saving, advantage such as processing procedure is easy, cost is low, high answer speed and full-colorization, make organic luminous panel have great application potential, be expected to become the illumination of follow-on flat-panel screens and planar light source, comprise special light sources and general lighting.
Generally speaking, organic luminous panel comprises a substrate, at least one organic illuminating element (Organic electroluminescent Device).Wherein, this organic illuminating element comprises one first electrode, an organic luminous layer and one second electrode.Wherein, the substrate and first electrode are light-transmitting materials, and first electrode and second electrode are respectively as anode and negative electrode; The electricity hole is injected by first electrode when imposing an electric current in organic illuminating element, electronics is injected by second electrode simultaneously, at this moment, because the potential difference that extra electric field caused, make carrier in organic luminous layer, move, meet and produce combination again, can excite light emitting molecule in the organic luminous layer and combine the exciton (exciton) that is produced with electric hole by electronics, the light emitting molecule of excitation state gives off energy with the form of light then.
From the above, the normal dedining mechanism that takes place is the not generation of light-emitting zone (dark area) in organic illuminating element, this is because the organic functional material in the organic luminous element structure and easy and airborne moisture and oxygen reaction (especially moisture) as second electrode of negative electrode cause the not generation of light-emitting zone.Therefore to promote the durability (durability) of organic illuminating element, just be how to reduce the not generation of light-emitting zone.So, generally when making organic illuminating element, can under vacuum state, carry out plated film usually, and the mode to encapsulate, organic illuminating element is sealed.
Yet in manufacture process, residual trace water, metal electrode forms the moisture content that diffusion is entered in each interface, back and the organic layer in the contained moisture content of the water of substrate surface, organic material, the vacuum evaporation cavity, and the back diffusion of the component package moisture content of entering or the like, even make to be the not element of water content of bone dry when just finishing, after through subsequent treatment and use a period of time, just can cause the breakage of collapsing of the organic luminous layer in the organic illuminating element and second electrode from, organic material, and the oxidation of electrode etc.Improve the not generation chance of light-emitting zone again, also reduced the luminosity of element and luminous uniformity.Component life is produced great influence; Therefore, how continuing isolated component and water oxygen and take place with the problem of avoiding deterioration, is considerable problem.
As mentioned above, in order to prevent the not generation of light-emitting zone, and then promoting the life-span and the stability of organic illuminating element, primarily is to avoid airborne moisture in follow-up use, enters organic illuminating element inside successively.Please refer to shown in Figure 1ly, organic luminous panel 1 comprises a substrate 11 and an organic illuminating element 12.Organic illuminating element 12 is arranged on the substrate 11, and this organic illuminating element 12 comprises one first electrode 121, an organic luminous layer 122 and one second electrode 123.Existing encapsulation technology is to utilize the UV adhesive material to be used as binder (adhesives), with point gum machine with adhesive material coat desire the involution element around, then with a cover plate 14 and substrate 11 pressings, at last again via UV-irradiation, make the sclerosis of UV adhesive material, form an adhesive layer 13 between cover plate and substrate.
For the further barriering effect of strengthening water oxygen, prior art once utilized the glue that increases with substrate bonding place wide, or the sealing that many again cloth one enclose in the periphery of original sealing.But above-mentioned way can increase the size of adhesive area and the consumption of adhesive material, goes up the number that can reduce element output on the substrate relatively, makes production cost improve.
Except improving the penetrability of sealing to water oxygen, on the other hand, the inorganic material that existing technology is used the quality densification mostly (for example: SiO
2, Si
3N
4, MgO, Al
2O
3And MgF
2Deng) be deposited on above the organic illuminating element, form passivating film (passivation film) and come protection component.When making passivating film, if the thickness of passivating film is too thin, then just relatively poor to the barrier performance of moisture and oxygen, and the flatness on surface is also relatively poor; If under vacuum state, passivating film is deposited (deposit) on element, and increase passivation film thickness, this kind practice no doubt can be improved above-mentioned problem, but thicker passivating film then needs long sedimentation time, so can improve production cost.Except that this, when the thickness of passivating film increases, make the contraction or expansion of organic illuminating element be restricted, thereby have the generation of stress, when serious even can produce the phenomenon of demoulding, and can't reach the effect of protection component.
Therefore, in order to solve above-mentioned problem, how to provide a kind of processing procedure simple organic illuminating element, and has the surface that to avoid water oxygen and pollutant to attach, effectively reducing water oxygen enters in the organic illuminating element, and then avoid the quality badness of organic luminous layer and electrode, this is one of important topic of current opto-electronics.
Summary of the invention
At the problems referred to above, purpose of the present invention provides a kind of organic luminous panel with hydrophobic layer, and hydrophobic layer can reduce water oxygen and pollutant is built-up in organic illuminating element, and reduces the chance of the organic illuminating element that water oxygen enters.
Edge is, for reaching above-mentioned purpose, the invention provides a kind of organic luminous panel with hydrophobic layer, comprises a transparency carrier, at least one organic illuminating element, at least one protective layer and at least one hydrophobic layer.In the present invention, organic illuminating element is arranged on the transparency carrier, and organic illuminating element comprises one first electrode, at least one organic luminous layer and one second electrode in regular turn; Protective layer is located on the transparency carrier or is formed a closed system on second electrode and with substrate, and first electrode, organic luminous layer and second electrode are arranged in closed system; Hydrophobic layer is formed on the protective layer or the outer surface of closed system, enters organic illuminating element to prevent water oxygen.
