It should be noted that, in other embodiments of the invention, light scattering rete also can be arranged at the outer surface of encapsulation cover plate, or is arranged on outer surface and the inner surface of encapsulation cover plate simultaneously.
The size of micro-structural 201 is positioned at visible wavelength range, or be positioned near visible wavelength range, thereby the visible light ray that micro-structural 201 can be sent Organic Light Emitting Diode 10 carries out scattering, make described light after micro-structural 201, disperse to propagate, reach the effect that can see from different perspectives described light.Because a plurality of micro-structurals 201 are orderly matrix, be arranged in encapsulation cover plate 2 inner surfaces, so the scattering process of 201 pairs of light of each micro-structural is identical, thereby the light that light scattering rete 20 can be produced Organic Light Emitting Diode 10 carries out scattering equably.Organic Light Emitting Diode 10 can be divided into a plurality of dot structures, the corresponding light of each dot structure through light scattering rete 20 by scattering equably, thereby make display frame there will not be colour cast problem.
In the present embodiment, described organic LED display panel has active electrode portion 101, and active electrode portion 101 comprises the active Drive Structure such as thin-film transistor that matrix is arranged, therefore described organic LED display panel is active matrix type organic light emitting diode display floater.Simultaneously, in described organic LED display panel, organic luminous layer 104 is positioned at reflection electrode layer 103 surfaces, transparent electrode layer 105 is positioned at organic luminous layer 104 surfaces, and the light that light produces from organic luminous layer 104 spreads out of from transparent electrode layer 105, and therefore described organic LED display panel is top emission type organic LED display panel.It should be noted that, in other embodiments of the invention, described organic LED display panel can be only also a kind of in active matrix type organic light emitting diode display floater and top emission type organic LED display panel, or can also be end emission type Organic Light Emitting Diode.

Please refer to Fig. 2, Fig. 2 is the schematic perspective view of encapsulation cover plate 2 in organic LED display panel shown in Fig. 1.
As can see from Figure 2, light scattering rete 20 is formed on encapsulation cover plate 2 inner surfaces (now encapsulation cover plate 2 inner surfaces upward), the micro-structural 201 that forms light scattering rete 20 is matrix and is arranged on encapsulation cover plate 2 inner surfaces, and each micro-structural 201 is tetrapyamid shape.
Please refer to Fig. 3, Fig. 3 is the tangent plane schematic diagram of the encapsulation cover plate broad ways of organic LED display panel shown in Fig. 2, that is the profile that obtains along A-A dotted line cutting of encapsulation cover plate 2.
For guaranteeing that light scattering rete 20 has good scattering process, the thickness H that light scattering rete 20 is set is greater than or equal to 0.05 μ m, but simultaneously, in order to prevent that light scattering rete 20 is too thick and other structure is impacted, and in order to save process time and cost of manufacture, the thickness H that light scattering rete 20 is set is less than or equal to 2 μ m, and therefore, the scope of the thickness H of described light scattering rete 20 can comprise 0.05 μ m～2 μ m.
Because micro-structural 201 is tetrapyamid shape, therefore in the profile shown in Fig. 3, micro-structural 201 is triangle zigzag, and for making micro-structural 201 can both carry out preferably geometry scattering to all visible rays, it is 0.1 μ m～1 μ m that micro-structural 201 width L scopes are set.Same, the length range that micro-structural 201 is set is also 0.1 μ m～1 μ m.
It should be noted that, in other embodiments of the invention, micro-structural can be also other pyramid-shaped, such as Rhizoma Sparganii taper, pentagonal pyramid shape or hexagonal pyramid shape etc.In addition, micro-structural can also be coniform or prism-frustum-shaped.
