Fig. 2 is the schematic diagram of OLED display provided by the utility model.

Embodiment

The utility model is described in detail with reference to the accompanying drawings and examples.

Embodiment one

As shown in figure 1, a kind of ito substrate, including underlay substrate 1 and it is successively set on inclined on the underlay substrate 1 Photosphere 2 and ITO layer 4.

The ito substrate is integrated with polarizing layer 2 between underlay substrate 1 and ITO layer 4, and it has the function that polaroid, is making Without pasting polaroid in addition when making OLED display, the production cost of OLED display can be reduced, improve color saturation, increased Add angular field of view, and targetedly regulation is carried out to the thickness of the polarizing layer 2 set for the structure of different OLEDs Meter；In addition, the polarizing layer 2 can be fabricated to multiple color according to demand, the screen of OLED display is set to be in when not showing Reveal multiple color, enrich the outward appearance diversity and practicality of OLED display.

The polarizing layer 2 is color layer, the polarizing layer 2 is made using the polarizing materials of different colours, so that OLED shows Show that the screen of device when not showing, shows multiple color；The color layer is any in red, orange, yellow, green, blue, blue, purple Kind or multiple combinations.

The polarizing layer 2 is made using the material such as polyvinyl alcohol or light polarizing dye or polarized ink, and preparation method includes But it is not limited to physical vapour deposition (PVD) or chemical vapor deposition or spin-coating method etc..

Separation layer 3 is provided between the polaroid and ITO layer 4, for the polarizing layer 2 and ITO layer 4 to be isolated, Prevent from interfering the normal work of OLED；The separation layer 3 must use the material that property is stable and translucency is good, than Such as silica or alundum (Al2O3), preparation method preferably use physical vapour deposition (PVD).

The underlay substrate 1 is glass substrate or sapphire substrate or plastic base etc..

The making step of the ito substrate；The polaroid first is made on the underlay substrate 1, then makes the isolation Layer 3, finally makes the ITO layer 4, you can complete the making of the ito substrate；, only need to be by described in when making OLED display ITO layer 4 is carried out being lithographically formed anode pattern, and OLED work(is formed as the anode layer of OLED display, and carrying out plated film successively Ergosphere and cathode layer, finally encapsulate and bind driving IC, complete the making of whole OLED display.

Embodiment two

As shown in Fig. 2 a kind of OLED display, including above-mentioned ito substrate, the ITO layer 4, which makes, anode pattern, The underlay substrate 1 makees exiting surface；Also include bonnet substrate 7, pass through fluid sealant 8 between the underlay substrate 1 and bonnet substrate 7 Sealing is fixed, and the polarizing layer 2 and ITO layer 4 are set gradually in the one side close to the bonnet substrate 7, the ITO layer 4 There are OLED functional layers 5 and cathode layer 6.

Touch-screen is provided with the exiting surface of the underlay substrate 1（It is not shown）.

The cathode layer 6 is metal material；The bonnet substrate 7 is glass substrate or sapphire substrate or plastics base Plate.

Embodiment described above only expresses embodiment of the present utility model, and its description is more specific and detailed, but simultaneously Therefore the limitation to the utility model patent scope can not be interpreted as, as long as using equivalent substitution or the form of equivalent transformation institute The technical scheme of acquisition, it all should fall within the scope of protection of the utility model.
