In other embodiments, it is possible to dispersion effect according to actual needs adjusts the diameter of PS microsphere. The thickness of the PDMS layer 12 of the present embodiment is 3 ��m, in other embodiments, it is also possible to select the preferential scope of 2 ��m to 4 ��m.
The present invention adopts cathode electrode unit 24 and anode unit 22 to be staggered in organic luminous layer both sides, organic luminous layer is made to go out light from the gap between anode unit 22, and the gap injection between cathode electrode unit 24, realize double-side, anode unit 22 and cathode electrode unit 24 partly overlap in position, it is ensured that can complete corresponding luminescence process.
The shape of substrate 21 can be plane, it is also possible to be curved surface. Substrate 21 can by insulant, as glass, quartz, pottery or plastics formed. In some embodiments, substrate 21 may further include the cushion formed on substrate, for preventing the diffusion of foreign ion, preventing the infiltration of dampness and extraneous air and ensure that substrate 21 surface is smooth.
Substrate 21 can include multiple pixels of matrix form arrangement, and each pixel includes luminous zone and non-light-emitting area. That is, substrate 21 can include multiple luminous zone and multiple non-light-emitting area, and luminous zone and non-light-emitting area can be alternately arranged. Wherein, each luminous zone can be form organic luminous layer and send the region of light from organic luminous layer, and each non-light-emitting area can be the region forming the thin film transistor (TFT) for driving organic luminous layer.

Organic luminous layer 23 can be arranged on anode unit 22. Organic luminous layer 23 can send the light of varying strength according to the size of current flow through. Concrete, it is provided that hole and electronics to organic luminous layer 23 can be combined together to form exciton, and when the energy level of exciton becomes ground state from excited state, organic luminous layer 23 can send the light corresponding with energy level knots modification. Organic luminous layer 23 in each pixel can send the light of a kind of color. According to the organic material forming organic luminous layer 23, organic luminous layer 23 can send HONGGUANG, green glow or blue light.

Organic luminous layer 23 is provided with first refractive layer 31, cathode electrode unit 24 is provided with the second refracting layer 32. Wherein, first refractive layer 31 can absorb external impact, it is prevented that external impact is transferred to the thin film transistor (TFT) on substrate 21 and on organic luminous layer 23. Additionally, first refractive layer 31 can by absorb and cool down from organic luminous layer 23 produce heat suppress interior-heat.
Owing to first refractive layer 31 is arranged on organic luminous layer 23, therefore the area of first refractive layer 31 is substantially equal to the area of each luminous zone. Second refracting layer 32 is arranged on cathode electrode unit 24, and therefore, first refractive layer 31 and the second refracting layer 32 are planar alternately arranged. First refractive layer 31 is arranged in the second refracting layer 32 with matrix pattern. Owing to the second refracting layer 32 is arranged on cathode electrode unit 24, not overlapping with organic luminous layer 23, it is not the directapath that light to pass through.

Second refracting layer 32 includes the refractive index low-index material less than 1.6. Low-index material can be distributed in the whole surface of the second refracting layer 32, to reduce total refractive index of the second refracting layer 32. Or, it is possible to it is distributed in the boundary of first refractive layer 31, to reduce by second refracting layer 32 refractive index at boundary.
The height that high-index material can be poly-diaromatic siloxane, MTMS or tetramethoxy-silicane reflects curable polysilicon. Low-index material can be the low refraction ultraviolet-curing acrylate copolymer of acrylic acid ethyl ethyl ester, acrylic acid five fluorine propyl ester, PEG dimethylacrylate or ethylene glycol dimethacrylate.
When light moves to low refractive medium from high refractive medium, it is possible to refract to low refractive medium or reflect paramount refractive medium. Therefore, the light of the second refracting layer 32 entering low-refraction from the first refractive layer 31 of high index of refraction can refract to the second refracting layer 32 or reflex to first refractive layer 31.The angle of incidence that the path of light can be incided in the boundary face between first refractive layer 31 and the second refracting layer 32 by light is determined.
Said structure enables refracting layer to be gathered in by light in the first refractive layer 31 that each luminous zone is corresponding, therefore, first refractive layer 31 can improve luminous efficiency, in addition, said structure can make light minimize to the diffusion of the second refracting layer 32, it is possible to substantially prevents the color mixture between pixel.
In sum, electroluminescent display provided by the invention, compared to prior art, have the advantages that
1, by increasing PDMS layer in the bottom of substrate and embedding the monolayer PS microsphere layer of PDMS layer, can effectively reduce and the total reflection at substrate exiting surface occurs, improve beam projecting rate.
