Before the present invention is described in detail, it should be noted that in the following description, similar elements are denoted by the same reference numerals.

The foregoing and other technical aspects, features, and advantages of the present invention will be apparent from the Detailed Description of the <RTIgt;

First embodiment

Referring to Figures 1 and 2, a first embodiment of the novel light-emitting display device 1 is shown. As an application of an organic light emitting display, the light emitting display device 1 A light emitting component 2 and a package component 3 are included.

The light-emitting component 2 is configured to provide image light of the light-emitting display device 1 , and includes a substrate 21 , a light-emitting structure 22 disposed on the substrate 21 , and a sealing structure 23 disposed on the substrate 21 and surrounding the light-emitting structure 22 . The space defined by the substrate 21 and the sealing structure 23 has an upper opening 24. The light-emitting structure 22 uses an organic light-emitting diode (OLED) as a display light source, and has a lower electrode layer 221, a light-emitting layer 222, and an upper electrode layer 223 which are sequentially disposed from bottom to top. The light-emitting layer 222 is the main light-emitting layer of the light-emitting structure 22, and is formed by stacking a plurality of organic materials (not shown in the drawing). The lower electrode layer 221 and the upper electrode layer 223 are electrode structures that provide power required for the light emitting structure 22, and both may be made of a transparent conductive material such as Indium Tin Oxide (ITO) or silver nanowire. ), carbon nanotubes, conductive polymers (PEDOT/PSS), metal mesh, graphene (Graphene) and other materials, but the lower electrode layer 221 has a high reflectivity (such as metal Material) is better made.

The package assembly 3 at least partially covers the upper opening 24 of the light-emitting assembly 2 and includes a brightness-increasing anti-reflection structure 31 and a cover plate 32.

The brightening anti-reflection structure 31 is used for mitigating the reflection phenomenon caused by external light, and can improve the image light use efficiency of the light-emitting structure 22, and has a linear polarizing layer 311, a reflective polarizing layer 312, and a quarter-wave plate 313.

The line polarizing layer 311 is disposed away from the light emitting component 2 for polarizing a line having a first linear polarization direction (a horizontal arrow extending in the x-axis direction in FIG. 2) and blocking a second line. Polarization direction (Figure 2 The line of the oblique arrow extending in the y-axis direction passes through the polarized light, and the second linear polarization direction is perpendicular to the first linear polarization direction.

The quarter-wave plate 313 is disposed adjacent to the light-emitting assembly 2, and polarizes the linearly polarized light polarized in the first linear polarization direction and the circularly polarized light polarized in a first circular polarization direction (the circular arrow in the clockwise direction in FIG. 2). Converting, or converting linearly polarized light polarized along the second linear polarization direction and circularly polarized light polarized in a second circular polarization direction (cyclic arrow in the counterclockwise direction in FIG. 2), the second circular polarization direction and The first circular polarization directions are opposite to each other.

The reflective polarizing layer 312 is disposed between the linear polarizing layer 311 and the quarter-wave plate 313 for transmitting a linearly polarized light having a first linear polarization direction and reflecting a linearly polarized light having a second linear polarization direction.

The cover plate 32 is provided on the other side of the linear polarizing layer 311 opposite to the reflective polarizing layer 312 to provide protection.

Referring to FIG. 2, according to the structure of the brightness enhancement anti-reflection structure 31, it is assumed that the light L41 of the external environment has a first linear polarization direction and a second linear polarization direction, and after the light-emitting display device 1 is irradiated through the linear polarization layer 311, the line The polarizing layer 311 blocks the portion of the second linear polarization direction to convert the light into the linear polarized light L42 of the first linear polarization direction. Subsequently, the linearly polarized light L42 can pass through the reflective polarizing layer 312 and be converted to the circularly polarized light L43 having the first circular polarization direction at the quarter-wave plate 313. Then, the circularly polarized light L43 is reflected by the light emitting structure 22 (mainly at the lower electrode layer 221) to form a circularly polarized light L51 of a second circular polarization direction, and the circularly polarized light L51 is converted into a second linear polarization direction by the quarter wave plate 313. The line polarized light L52 is reflected by the reflective polarizing layer 312 and faces the quarter-wave plate 313, and is converted by the quarter-wave plate 313 into Circularly polarized light in the second linear polarization direction (not shown). The circularly polarized light is reflected by the light-emitting structure 22 to form a circularly polarized light of a first circular polarization direction, and the circularly polarized light can smoothly pass through the quarter-wave plate 313, the reflective polarizing layer 312, and the linear polarizing layer 311, respectively, to form a first The linear polarization direction of the line is polarized, but at this time, the light intensity is much smaller than the light L41 originally incident in the external environment, so that the brightening anti-reflection structure 31 can slow the reflection of the surface of the screen.

On the other hand, after the image light L61 generated by the light emitting structure 22 passes through the quarter wave plate 313, a portion thereof passes through the reflective polarizing layer 312 to form a linear polarized light L62 of a first linear polarization direction, and the linear polarized light L62 can be smoothly worn. The linear polarizing layer 311 passes through the display screen; and the linear polarized light L63 of the second linear polarization direction reflected by the reflective polarizing layer 312 passes through the quarter-wave plate 313 to form a circular polarized light L64 of the second circular polarization direction. The circularly polarized light is reflected by the light emitting structure 22 (mainly at the lower electrode layer 221) to form a circularly polarized light L71 of a first circular polarization direction, and the circularly polarized light L71 is converted into a first linear polarization direction by the quarter wave plate 313. The line polarized light L72 can smoothly pass through the reflective polarizing layer 312 and the linear polarizing layer 311 to pass out of the display screen. Therefore, most of the image light L61 generated by the light-emitting structure 22 can penetrate outside the brightness-increasing anti-reflection structure 31. Therefore, the brightness-increasing anti-reflection structure 31 of the present invention can effectively improve the image light use efficiency of the light-emitting structure 22.

In the present embodiment, the linear polarizing layer 311 may be a polarizing plate made of a material such as a polymer iodine polymer or an absorbing polarizing layer made of a liquid crystal molecule using a dichroic dye.

A polarizing plate made of a polymer iodine polymer is a film material produced by stretching, for example, polyvinyl alcohol (polyvinyl alcohol) A film called PVC) is formed by stretching in an iodine-containing solution, and may be further subjected to hard coating to increase its strength. If the linearly polarized polymer iodine-based polymer polarizing plate is used for the linearly polarizing layer 311 of the light-emitting display device 1, the surface of the light-emitting layer 311 does not need to be provided with a cover 32 (see FIG. 3), that is, in this case. The display device 1 may not be provided with the cover 32, but it is required to be bonded by an adhesive layer between the polarizing plate made of a polymer iodine-based polymer and other layers during the manufacturing process.

On the other hand, unlike the polarizing plate made of the polymer type iodine-based polymer of the film type, the absorbing polarizing layer made of the dichroic dye and the liquid crystal molecules is a coated linear polarizing layer produced by a coating process. The dichroic dye has a special absorption property for polarized light. Taking a disc-shaped dye dichroic molecule as an example, it only allows the light component perpendicular to the molecular direction to pass, and absorbs the light component parallel to the molecular plane, thus controlling it. The molecular direction can set the polarization direction of the polarizing layer. In addition, since the dichroic dye molecules do not have the characteristics of liquid crystals, they can be mixed with nematic liquid crystal molecules and applied in a material-guest-host (GH) mixed mode material property, which is The polarized light component and the vertically polarized light component have different absorption characteristics, and thus can be applied to the fabrication of the polarizing layer. In the manufacturing process, the dichroic dye and the liquid crystal molecules can be directly coated on various substrates to form a polarizing layer, and the polarizing plate made of a relatively high molecular iodine polymer is thin and does not need to be adhered. The layer is bonded to the substrate, thus contributing to the thinning of the overall structure.

The quarter-wave plate 313 may be a plate-like material made of a polymer film such as polyimide (PI), or a reaction type liquid may be used. An optical layer made of crystalline molecules. Similar to the linear polarizing layer 311, if the quarter-wave plate 313 is made of a polymer material, the adhesive layer is required to be bonded to the other layers. If a quarter-wave plate 313 made of liquid crystal molecules is used, its thickness is thinner than that of the polymer film, and it is not necessary to bond the other layers by the adhesive layer, so that the thickness between the layers can be reduced.

In addition, the reflective polarizing layer 312 of the present embodiment uses a multi-level double brightness enhancement film (DBEF), which is a hard plate material and is composed of a multilayer film optical film (not drawn in the figure). ). In some embodiments, the reflective polarizing layer 312 needs to be bonded to other layers by an adhesive layer.

It should be particularly noted that, in the foregoing description, the correspondence between the first linear polarization direction, the second linear polarization direction, the first circular polarization direction, the second circular polarization direction, and the spatial coordinate axes x, y, and z It is only used for the description of the embodiment, but the scope of implementation of the present invention should not be limited by this content. For example, the first linear polarization direction and the second linear polarization direction may also correspond to the y-axis direction and the x-axis direction, respectively. The circular polarization direction and the second circular polarization direction may also be counterclockwise and clockwise, respectively, which is a technical content that can be adjusted according to the above description by those skilled in the art.

On the other hand, in the above description, the light-emitting display device 1 of the present embodiment will be described with an embodiment in which the cover 32 is provided. However, in the case where the linear polarizing layer 311 of the light-emitting display device 1 is a surface-treated (hardened) hard plate material (for example, a polarizing plate made of the above-described polymer iodine-based polymer), the light-emitting display device 1 may not be provided. The cover plate 32, that is, the light-emitting display device 1 is a surface directly facing the surface-treated linear polarizing layer 311 as a display screen.

Referring to Fig. 7, a variation of the second embodiment of the novel light-emitting display device 1 is shown. Since the cover layer 32 is not provided in the embodiment, the first touch electrode layer 331 is not suitable to be directly disposed on the surface of the linear polarizing layer 311. The first touch electrode layer 331 needs to be disposed between the linear polarizing layer 311 and the reflective polarizing layer 312, between the reflective polarizing layer 312 and the quarter-wave plate 313, or on the quarter-wave plate. 313 and the light-emitting component 2 (as shown in Figure 7) to achieve the efficacy of the present invention.
