Referring to fig. 1, an exemplary structural block diagram of an organic light emitting display panel according to an embodiment of the present application is shown. An organic light emitting display panel including a substrate, a thin film transistor layer, and a planarization layer 11, the organic light emitting display panel having a non-display D1 region and a display region D2, further comprising:
the pixel defining layer is positioned on the flat layer 11, the pixel defining layer is provided with a first recess which is recessed in the thickness direction of the pixel defining layer, a concave curved first electrode layer 21 and a concave curved light-emitting layer 22 are stacked in the first recess, the first electrode layer 21 is adjacent to the pixel defining layer, and a second electrode layer 23 is arranged on the pixel defining layer;
the packaging layer 15 is positioned on the second electrode layer 23, the packaging layer 15 is provided with a second recess which is recessed in the thickness direction of the packaging layer, and a convex lens 31 is arranged in the second recess;
the anti-interference layer is positioned on the packaging layer 15 and is provided with a light hole 19; the light emitted from the curved light emitting layer 22 is condensed by the convex lens 31 and emitted to the outside through the light transmitting hole 19.
The convex lens is a microlens, and one sub-pixel has one microlens. Thereby forming a microlens array throughout the display panel. The microlens array is an array composed of lenses with micron-sized clear aperture and relief depth, not only has basic functions of focusing, imaging and the like of the traditional lens, but also has the characteristics of small unit size and high integration level, so that the functions which cannot be completed by the traditional optical element can be completed, and a plurality of novel optical systems can be formed.
The convex lens arranged on each sub-pixel forms a micro-lens array, and focuses light emitted by the curved light-emitting layer on a focal plane. And a light-transmitting hole 19 is provided at each focusing point so that light of the focusing point is transmitted therethrough, as shown in fig. 1.
In order to focus light emitted from the light emitting layer in the light transmitting hole, the light emitting layer is provided as a concave curved surface which is easily focused by the convex lens.
The curved surface luminescent layer combines together with spotlight convex lens, makes display screen self light propagation avoid the light path of most external environment light, and the light of focus jets out through the light trap on jam-proof layer, and the external natural light is absorbed through the most external light on jam-proof layer. The purpose of reducing the reflection of the display screen to the external environment light and simultaneously ensuring the transmittance of the display screen is achieved.
In order to make the structures among the first electrode layer, the light emitting layer 22 and the second electrode layer 23 compact and facilitate the focusing of light, the portions of the first electrode layer 21, the second electrode layer 23 and the light emitting layer 22, i.e. the display areas of the three film layers, adopt a curved surface structure.
It should be noted that, in the side view in the figure, the light emitting layer is arc-shaped, and is a concave curved surface in the stereoscopic effect, and the curvature of the curved surface is set according to the structure of the convex lens, which is not described herein again.
In some embodiments, the pixel defining layer includes a first pixel defining layer 13 and a second pixel defining layer 14;
the flat layer 11 is provided with a first pixel defining layer 13, and a display area D2 of the first pixel defining layer 13 is provided with a first recess;
the second pixel defining layer 14 is positioned on the first pixel defining layer 13 and is positioned in the non-display region D1.
In order to distinguish regions corresponding to the display region D2 and the non-display region D1 in each layer, the regions are divided by dotted lines in fig. 1. The area of the packaging layer adjacent to the convex lens is also a curved surface structure. The pixel defining layer is divided into a first pixel defining layer and a second pixel defining layer, wherein the second pixel defining layer positioned in the non-display area adopts a black light absorption material, and is beneficial to absorbing external natural light.
In some embodiments, the convex lens is a hemispherical lens. With a hemispherical lens, the spherical portion is adjacent the encapsulant layer 15 and the planar portion is adjacent the tamper-proof layer. The convex lens may be a biconvex lens, a plano-convex lens. The plano-convex lens may further be a hemispherical lens. In material, the convex lens can be made of BK7 glass or resin material, and when the BK7 glass hemispherical lens is adopted, the selectable refractive index is about 1.517.
In some embodiments, the tamper-proof layer comprises honeycomb structures 17, the lateral edges of the hexagonal prisms of the honeycomb structures 17 being parallel to the planar layer. This is explained below with reference to fig. 2 to 5. Wherein fig. 2 illustrates an exemplary perspective view of a honeycomb structure according to an embodiment of the present application; FIG. 3 illustrates an exemplary side view of a honeycomb structure according to an embodiment of the present application; FIG. 4 illustrates an exemplary front view of a honeycomb structure according to an embodiment of the present application; fig. 5 illustrates an exemplary optical path schematic of a honeycomb structure according to an embodiment of the present application.
As shown in fig. 2 to 4, the side edges 171 of the regular hexagonal prism of the honeycomb structure are parallel to the flat layer. The honeycomb structure adopts the nanotechnology, and the structure has the advantages that the adhesion degree is good, the thickness of the honeycomb structure, namely the number of layers of the hexagonal prisms, can be adjusted according to requirements, and the interference of ambient light is effectively controlled.
As shown in fig. 5, when ambient light enters the honeycomb structure, the light enters the honeycomb after being refracted on the surface, and is reflected and transmitted repeatedly inside, so that the optical path of the light is increased, most of light energy is consumed, part of light is emitted from the port of the hexagonal prism, and only a small part of light is transmitted to the lower layer, so that the purpose of absorbing external light is achieved. The honeycomb structure may be made of a transparent material or a light-absorbing material.
When the interference prevention layer includes only the honeycomb structure, the honeycomb structure 17 is provided on the sealing layer 15, and the light transmission holes 19 are formed in the honeycomb structure and located at the collection points of the light emitting layer 22 formed by the convex lenses 31.
In some embodiments, the tamper-proof layer includes a black light absorbing layer 16. It should be noted that when the interference preventing layer only includes the black light absorbing layer, the black light absorbing layer is disposed on the encapsulation layer 15, and a light transmitting hole is formed on the black light absorbing layer 16, and the light transmitting hole is located at a focus point formed by the convex lens of the light emitting layer.
In some embodiments, the tamper-proof layer includes a black light absorbing layer 16 and a honeycomb structure 17, which are disposed on the encapsulation layer in this order. At this time, a small portion of the light transmitted through the honeycomb structure is absorbed by the black light absorbing layer. The interference of the ambient light is reduced.
It should be noted that the order of the black light absorbing layer 16 and the honeycomb structure 17 on the encapsulation layer can be interchanged, that is, the honeycomb structure and the black light absorbing layer are sequentially disposed on the encapsulation layer. At this time, part of the light passing through the black light absorbing layer is consumed by the honeycomb structure, and the interference of the ambient light is further reduced.
Further, the anti-reflection film layer 18 is arranged close to the anti-interference layer, and the anti-reflection film 18 is a multilayer anti-reflection film.
The antireflection film can increase the incidence of ambient light into the display screen and reduce the reflection of the ambient light. The natural light has seven colors and a certain bandwidth, and a single-layer antireflection film only has complete antireflection effect on monochromatic light with a certain wavelength, so that the multilayer antireflection film of the antireflection film with multiple colors in the natural light is correspondingly increased, the light transmittance of the natural light can be improved, and the light of the ambient light entering the display screen is increased.
