Embodiment
Below in conjunction with accompanying drawing embodiment of the present utility model is described further.
Fig. 1 shows the cross section structure synoptic diagram of described lightening high color saturation OLED with polaroid; described polaroid supremely comprises from top to bottom successively from last: diaphragm 5 outside a stripping film 1, first inner protection film 2, polyvinyl alcohol (PVA) (PVA) film 3, second inner protection film 4 and, more than each layer structure by the sticker bonding connection
Described polyvinyl alcohol (PVA) (PVA) film 3 needs dichroic substance such as absorption iodine, dichroic dye, then so that crosslinked, stretch and dry.Described polyvinyl alcohol film 3 adopts water to clean, and so not only can remove the dirt on striping surface or wash detackifier off, can also make polyvinyl alcohol film 3 expansions to prevent as the phenomenon such as inhomogeneous that dyes.Very fragile after described polyvinyl alcohol film 3 stretches, in order to protect polyvinyl alcohol film 3, need to be respectively first inner protection film 2 and second inner protection film 4 at its two sides composite protection film; Described the one the second inner protection films 2 and 4 material; the diaphragm that need possess excellent specific properties such as the transparency, physical strength, thermal stability, moisture barrier, isotropy; as cellulosic resins such as Triafol Ts, polynorbornene class, polycarbonate-based, polystyrene type, cyclenes hydro carbons, acrylic compounds etc.
Described second inner protection film 4 is preferably three cellulose acetate membrane (TAC film); be preferably especially with alkali etc. the TAC film that saponification is handled has been carried out on its surface; described TAC film and PVA film are by the water soluble glue bonding connection, and described water soluble glue is preferably poly-ethanol glue.
In addition; produce reflection or glare phenomenon in order to solve the OLED display surface; second inner protection film 4 can adopt through the antireflection three cellulose acetate membrane (AR-TAC film) after the surface treatment; or anti-dazzle three cellulose acetate membrane (AG-TAC film); in order to increase the anti-scratch function; can also adopt sclerosis three cellulose acetate membrane (HC-TAC film), the concrete application according to the OLED display is selected according to qualifications.
Described first inner protection film 2 possesses with the identical characteristic of second diaphragm 4 except need; also need to have the phase compensation function; described first inner protection film 2 is for having the three cellulose acetate membrane (TAC film) or the cyclo-olefin-polymer films (COP film) of wide wave zone phase compensation film; with present technology, preferred TAC.To sum up, described first inner protection film 2 has had wide wave zone phase compensation function and the double-deck function of protecting polyvinyl alcohol film concurrently.Described wide wave zone phase compensation function is embodied in, and can provide phase difference value in the uniform face in 400nm～780nm wavelength coverage, has zero wavelength dispersibility.Described first inner protection film 2 is bonding agent with polyvinyl alcohol film 3 with optical cement (OCA) or optic-solidified adhesive.
