Embodiment
Below in conjunction with drawings and Examples, the present invention is described in detail.
Aforementioned and other technology contents, feature and effect for the present invention, in the detailed description of following cooperation with reference to graphic seven preferred embodiments, can clearly present.
first embodiment
Consulting Fig. 1 and Fig. 2, is the first preferred embodiment of luminous display unit 1 of the present invention.As the application of organic light emitting display, luminous display unit 1 comprises luminescence component 2 and a package assembling 3.
Luminescence component 2 is for providing the image light of luminous display unit 1, it comprises a substrate 21, and is located at ray structure on substrate 21 22 and and is located on substrate 21 and by ray structure 22 around interior hermetically-sealed construction 23, this substrate 21 coordinates with hermetically-sealed construction 23 space defined to have a upper shed 24.Ray structure 22 adopts Organic Light Emitting Diode (OLED) as display light source, and it has lower electrode layer 221, luminescent layer 222 and the upper electrode layer 223 from bottom to top sequentially arranged.Luminescent layer 222 is the main luminescent layer of ray structure 22, is formed (not drawing in figure) by multilayer organic material storehouse.Lower electrode layer 221 and upper electrode layer 223 are for providing the electrode structure of ray structure 22 required electric power, both can adopt transparent conductive material, as tin indium oxide (Indium TinOxide, referred to as ITO), the material such as silver-colored Nanowire (silvernanowire), carbon nanotube (Carbon nanotube), conducting polymer (PEDOT/PSS), metal grill (metalmesh), Graphene (Graphene) makes, but lower electrode layer 221 is made as good to have high reflectance (as metal material).
Package assembling 3 covers this upper shed 24 of luminescence component 2 at least partly, and comprises blast anti-reflection structure 31 and a cover plate 32.
The reflective phenomenon that blast anti-reflection structure 31 causes for slowing down extraneous light, and the image light service efficiency that can promote ray structure 22, it has line polarizing layer 311, reflective polarizer 312 and a quarter-wave plate 313.
Line polarizing layer 311 is located at away from this luminescence component 2 place, line polarisation in order to have a First Line polarization direction (lateral arrows extended along the x-axis direction in Fig. 2) by one passes through, and intercept a line polarisation with one second linear polarization (the oblique arrow extended along the y-axis direction in Fig. 2) and pass through, this second linear polarization is mutually vertical with this First Line polarization direction.
Contiguous luminescence component 2 place is located at by quarter-wave plate 313, by the line polarisation along First Line polarization direction polarization and mutually change along the rotatory polarization of one first circular polarization (in Fig. 2 clockwise ring-type arrow) polarization, or by the line polarisation along this second linear polarization polarization and mutually change along the rotatory polarization of one second circular polarization (in Fig. 2 anticlockwise ring-type arrow) polarization, this second circular polarization and this first circular polarization mutually reverse.
Reflective polarizer 312 is located between line polarizing layer 311 and quarter-wave plate 313, passes through in order to the line polarisation by with First Line polarization direction, and reflects the line polarisation that has the second linear polarization.
The opposite side of line polarizing layer 311 in contrast to reflective polarizer 312 be located at by cover plate 32, in providing protective effect.
Consult Fig. 2, according to the structure of above-mentioned blast anti-reflection structure 31, suppose that the light L41 of external environment has First Line polarization direction and the second linear polarization, it to irradiate and by after line polarizing layer 311 toward luminous display unit 1, line polarizing layer 311 can intercept the part of the second linear polarization, makes light transfer the line polarisation L42 of First Line polarization direction to.Subsequently, line polarisation L42 can pass reflective polarizer 312, and is converted to the rotatory polarization L43 with the first circular polarization in quarter-wave plate 313 place.Then, rotatory polarization L43 reflects to form the rotatory polarization L51 of the second circular polarization at ray structure 22 (mainly lower electrode layer 221 place), rotatory polarization L51 is by being converted to the line polarisation L52 of the second linear polarization after quarter-wave plate 313, towards quarter-wave plate 313 after this line polarisation L52 is reflected by reflective polarizer 312, and be converted to the rotatory polarization (non-icon) of the second linear polarization by quarter-wave plate 313.This rotatory polarization reflects the rotatory polarization of rear formation first circular polarization by ray structure 22, this rotatory polarization can successfully sequentially through after quarter-wave plate 313, reflective polarizer 312, line polarizing layer 311, form the line polarisation of First Line polarization direction, but now its luminous intensity is much smaller than the initial incident light L41 of external environment, and therefore blast anti-reflection structure 31 can slow down the reflective phenomenon of screen surface.
And on the other hand, the image light L61 produced by ray structure 22 is by after quarter-wave plate 313, it partially passes through the line polarisation L62 that reflective polarizer 312 forms First Line polarization direction, and this line polarisation L62 can pass through line polarizing layer 311 and appear outside display screen; And pass through the rear rotatory polarization L64 forming the second circular polarization of quarter-wave plate 313 by the line polarisation L63 of the second linear polarization of reflective polarizer 312 reflection, this rotatory polarization forms the rotatory polarization L71 of the first circular polarization after ray structure 22 (mainly lower electrode layer 221 place) reflection, this rotatory polarization L71 is by being converted to the line polarisation L72 of First Line polarization direction after quarter-wave plate 313, this line polarisation L72 can pass through reflective polarizer 312, line polarizing layer 311 and appearing outside display screen.Therefore, the final major part of image light L61 that ray structure 22 produces can penetrate outside blast anti-reflection structure 31, and therefore blast anti-reflection structure 31 of the present invention effectively can promote the image light service efficiency of ray structure 22.
In the present embodiment, the Polarizer that line polarizing layer 311 can use the materials such as macromolecule iodine based polymer to make or use dichroic dye (dichroicdye) arrange in pairs or groups liquid crystal molecule make absorption polarizing layer.
The Polarizer that macromolecule iodine based polymer is made is the thin-film material made by stretching mode, such as can by polyvinyl alcohol (polyvinylalcohol, referred to as PVC) film to stretch formation, and can impose Surface hardening treatment (hardcoating) further to increase its intensity in Biodine.If the line polarizing layer 311 of luminous display unit 1 uses this kind through the macromolecule iodine based polymer Polarizer of Surface hardening treatment, then its surface can not arrange cover plate 32 (as Fig. 3), that is luminous display unit 1 can not arrange cover plate 32 in the case, but add man-hour in manufacture, need to be binded by adhesion layer between the Polarizer that macromolecule iodine based polymer is made and other layer.
On the other hand, the Polarizer that the macromolecule iodine based polymer being different from film shape is made, the absorption polarizing layer made by dichroic dye collocation liquid crystal molecule belongs to the cloth of coating-type line polarizing layer made by coating process.Dichroic dye possesses special absorption characteristic for polarised light, for disk Like dyestuff dichroic molecules, it only allows to pass through perpendicular to the light component of molecular orientation, and absorbs the light component being parallel to planes of molecules, therefore controls the light polar biased direction that its molecular orientation can set polarizing layer.In addition, because dichroic dye molecules does not possess the characteristic of liquid crystal, therefore it can be mixed with nematic liquid crystal molecules, with Host-guest (guest-host, referred to as GH) material behavior of mixed mode is applied, it has different absorption characteristics to horizontal polarization light component from vertical polarization light component, therefore can be applicable to the making of polarizing layer.In manufacture process, dichroic dye and liquid crystal molecule can directly be coated on various base material and form polarizing layer, the Polarizer that its thickness higher molecular iodine based polymer is made is thin, and does not need to be combined with substrate by adhesion layer, therefore contributes to integrally-built slimming.
The board-like material that quarter-wave plate 313 can use the polymeric membranes such as polyimides (polyimide, referred to as PI) to make, maybe can use the optical layers that reactive liquid crystals molecule is made.Similar with line polarizing layer 311, if the board-like material that quarter-wave plate 313 uses polymeric membrane to make, then need to be binded by adhesion layer between itself and other layer.If use the quarter-wave plate 313 that liquid crystal molecule is made, the thickness of itself is thinner than polymeric membrane, and does not need to be binded by adhesion layer and other layer, therefore can reduce the thickness between each layer.
In addition, the reflective polarizer 312 of the present embodiment uses multi-layer birefringence formula brightness enhancement film (dualbrightnessenhancementfilm, referred to as DBEF), it is the board-like material of hard, is made up of (not drawing in figure) the blooming of sandwich construction.In certain embodiments, reflective polarizer 312 needs to be binded by adhesion layer and other layer.
What illustrate is, in aforementioned description, this First Line polarization direction, second linear polarization, first circular polarization, second circular polarization and solid axes x, y, corresponding relation between z is only for the example explanation of the present embodiment, but should with this content constraints practical range of the present invention, such as First Line polarization direction, second linear polarization also can correspond respectively to y-axis direction, x-axis direction, and the first circular polarization, second circular polarization also can be counterclockwise respectively, clockwise direction, this knows the technology contents that the knowledgeable can be adjusted according to aforementioned explanation usually for this area has.
