The double-sided organic electroluminescent OLED lighting source is characterized in that each lighting unit is constructed by the cathode (4), the organic luminescent layer (3), the ITO anode (2) and the upper glass (1); and each lighting unit outputs through two lead wires and is arrayed on the packaging glass substrate (7), so that the double-sided organic electroluminescent OLED lighting source is constructed. A lead wire (5) and a lead wire (6) are respectively connected with the anode and the cathode of a power supply. The cathode of the lighting unit on the substrate glass is a transparent cathode, and besides, lighting units are arrayed on the same glass substrate. The lighting source can be luminescent at the two sides, so that the lighting area is enlarged, and the packaging is also simplified. The lighting source is rich in color, adjustable in color, diverse in pattern, good in uniformity and is convenient to use, and is a planar organic electroluminescent lighting source.
Description
[technical field]
Invention relates to a kind of lighting source, is specifically related to a kind of two-side organic electroluminescence OLED lighting source.
[background technology]
The back lighting mode of conventional ads board is fluorescent lamp, but the cost of its unit's of keeping illumination is very high.At present, led module commonly used replaces fluorescent lamp, and it is nearly 1/3 that its advantage is that power consumption can reduce, and the life-span reaches 60000h, and this will reduce the overall cost of equipment operation; The shortcoming of LED-backlit illumination is that the pitch between a plurality of LED has caused uneven illumination even.At present, Alpha-One company has developed a kind of white light LEDs module for billboard backlight and indirect lighting.This module has solved the even problem of uneven illumination of LED.
Compare with conventional light source, the advantage of OLED aspect energy-conserving and environment-protective is very obvious, and energy consumption is little, operating voltage is low, and is environment friendly and pollution-free, and have light, thin, luminous efficiency is high, power consumption is little, color is enriched the characteristics such as adjustable, anti-seismic performance excellence.The OLED life-span also rose to more than 10,000 hours, and luminous efficiency will significantly surpass fluorescent lamp.Along with the characteristics such as the brightness of OLED and life-span are able to the level used as illumination and the progressively reduction of OLED production cost gradually.
Compare with the led module light source, the substrate of OLED can be flexible material, and applying flexible is changeable, can be made into larger size.LED is point-source of light, in application process, need to consider the even problem of its uneven illumination, and OLED belongs to area source, does not have the even problem of uneven illumination.OLED can also be used to comparision of production Extraordinary opaque products.At present, also have many problems to exist for large-area OLED product, such as shortcomings such as large tracts of land film forming lack of homogeneitys.Therefore, with the OLED blocking and be packaged on the same substrate, and use transparent cathode OLED luminescence unit, so that encapsulation oversimplifies, and enlarged the field of illumination.
[summary of the invention]
Goal of the invention is, provides a kind of rich color and color adjustable, and figure is various, good uniformity, the complanation organic electroluminescent OLED lighting source of double-side.
The technical solution used in the present invention is: a kind of two-side organic electroluminescence OLED lighting source, comprise ito glass, organic luminous layer, transparent negative electrode and transparent substrate, it is characterized in that: comprise that from bottom to top packaged glass substrate, negative electrode, organic luminous layer, ito anode and upper glass consist of lighting unit, this lighting unit is by two wire outputs, and array consists of a kind of two-side organic electroluminescence OLED lighting source on transparent packaged glass substrate.
Described several OLED lighting units orthogonal array structure capable of being combined.
Described lighting unit is the OLED device of two-side transparent.
The manufacturing process of this lighting source is mainly several steps:
1) ito thin film on the ito glass (1) is carried out photoetching.2) ito glass good to etching (1) cleans.3) ito glass substrate is carried out plasma treatment.4) the vacuum chamber internal gas pressure when the vacuum coating machine reaches 10
-4During Pa, the organic function layer of evaporation OLED.5) transparent cathode of evaporation OLED in vacuum chamber.
By the transmission bar device is passed to punching high-purity N is arranged
2Glove box in encapsulate.Each OLED is packaged on the same substrate.
OLED be a kind of complanation display device, have easy to use.Uniformity of luminance is good, power saving, the characteristics such as manufacture craft is simple.But the OLED screen for large-area displays.Also have some performance of devices parameters not reach requirement, for example the life-span short, the shortcoming such as the large tracts of land film forming is inhomogeneous.Here we make undersized lighting unit with OLED screen, and make and be packaged on the same transparent substrate, and the uniformity of OLED film forming can improve like this, and quality improves, and it is easy that encapsulation also becomes.Adopt transparent cathode so that the illumination light-emitting zone enlarges, illuminating effect is better.
[description of drawings]
Fig. 1 is lighting unit side-looking structural representation of the present invention;
[embodiment]
1 couple of the present invention is described in further detail below in conjunction with accompanying drawing.
Referring to shown in Figure 1, this has two-side organic electroluminescence OLED lighting source, comprises packaged glass substrate 7, negative electrode 4, organic luminous layer 3, ito anode 2 and upper glass 1.Negative electrode 4, organic luminous layer 3, ito anode 2 consist of lighting unit with upper glass 1, and this lighting unit is by two wire outputs, and array consists of a kind of two-side organic electroluminescence OLED lighting source on packaged glass substrate 7.Wire 5 and wire 6 are connected respectively positive pole and the negative pole of power supply.The negative electrode of lighting unit is transparent cathode on the base plate glass, in addition on these cell arrays and the same packaged glass substrate.
The present invention is a kind of lighting source of double-side, and the negative electrode of its lighting unit is that transparent material is made, and light-emitting zone is larger.They are packaged on the same substrate, make and oversimplify.Provide a kind of rich color and color adjustable, figure is various, the lighting source of good uniformity.
