The shapes and sizes of the various elements in the drawings are not to scale and are merely intended to illustrate the invention.
Specifically, an embodiment of the present invention provides a display panel, as shown in fig. 1, including: the display device comprises a substrate base plate 1 and a plurality of sub-pixels 2 arranged in an array on the substrate base plate 1;
the light condensing structures 4 are positioned on one side of the light emitting surface of the sub-pixels 2 and are arranged in one-to-one correspondence with the sub-pixels 2;
the orthographic projection of the light-gathering structure 4 on the substrate 1 covers the orthographic projection of the sub-pixels 2 on the substrate 1.
Specifically, in the display panel provided in the embodiment of the present invention, the display panel includes: the substrate base plate is positioned on the plurality of sub-pixels which are arranged in an array manner; the light condensation structures are positioned on one side of the light emitting surface of the sub-pixels and are arranged in one-to-one correspondence with the sub-pixels; the orthographic projection of the light-gathering structure on the substrate covers the orthographic projection of the sub-pixels on the substrate. The light condensing structures corresponding to the sub-pixels one to one are arranged on one side of the light outlet of the display panel, and each light condensing structure covers all the area of the pixel, so that the light emitted by the whole sub-pixel is converged, and the light of each sub-pixel is emitted after being converged, so that the light intensity emitted by each sub-pixel is increased, and the display effect of the display panel is improved.
In the display panel according to the embodiment of the present invention, fig. 1 is a schematic view showing the display panel as an electroluminescent display panel, and the display panel includes an anode layer 21, a light-emitting layer 22, a cathode layer 23, and an encapsulation layer 3. However, the present invention is not limited to the application in the electroluminescent display panel, and may also be applied in the liquid crystal display panel, which is selected according to the practical application, and is not limited in particular.
When the light condensing structure is an axisymmetric pattern, the sub-pixel may also be set to be an axisymmetric structure having the same symmetry axis as the light condensing structure, and when the light condensing structure is a centrosymmetric pattern, the sub-pixel may also be set to be a centrosymmetric pattern having the same symmetry center as the light condensing structure. If the orthographic projection of the light-gathering structure on the substrate base plate is a circle, the sub-pixels can be arranged into a square positioned in the circle. The arrangement can increase the light condensation effect of the light condensation structure on light emitted by the sub-pixels.
As shown in fig. 2, when the light-gathering structures 4 are manufactured, due to the limitation of the etching process precision, a certain gap region exists between the light-gathering structures 4 (when the size of the sub-pixel is 3 μm by 4.5 μm, the pitch between adjacent sub-pixels is generally about 0.3 μm), so that light emitted by each sub-pixel 2 is emitted in the gap region, and a specific light path is shown by an arrow in fig. 2, so that a crosstalk phenomenon occurs between the sub-pixels 2. Fig. 3 is an angle-luminance correspondence diagram of the structural simulation in fig. 1, in which, as shown in a curve a, after light emitted from a sub-pixel is converged by a light-converging structure, luminance at a position of a front view angle is the largest, and in the process of 0 to 20 °, the luminance is sequentially decreased, and if no crosstalk occurs, the luminance is also decreased beyond 20 °, but after the crosstalk occurs, as shown in a curve b, an increase in light intensity also occurs between 20 ° and 80 °, and a peak is reached at 50 °, where the curve b only shows a change in luminance values at different angles on the right side, and the left side and the right side are symmetrically arranged (the left side is not specifically shown in the diagram), so that a curve corresponding to the angle and luminance in the curve a is obtained.
In order to avoid the problem of crosstalk between adjacent sub-pixels, optionally, in the display panel provided in the embodiment of the present invention, as shown in fig. 4, the display panel further includes: the shading structure 5 is positioned between the adjacent light-gathering structures 4;
the light-shielding structures 5 are configured to absorb the outgoing light at the gaps of the adjacent light-shielding structures 5.
Specifically, in the display panel provided in the embodiment of the present invention, as shown in fig. 4, light emitted from each sub-pixel 2 is irradiated to a gap region between adjacent light-condensing structures 4, and a certain amount of emergent light is emitted from the gap at the edge of the light-condensing structure 4. By providing the light shielding structure 5 having a light absorbing function in the gap, light emitted to the gap region can be absorbed, and the influence of light emitted from the gap region on the adjacent sub-pixels 2, that is, the crosstalk phenomenon of light emitted from the adjacent sub-pixels 2, can be avoided.
Optionally, in the display panel provided in the embodiment of the present invention, the light shielding structure is made of an organic light absorbing resin or a light absorbing metal.
Specifically, in the display panel provided in the embodiment of the present invention, the material of the light shielding structure may be an organic light absorbing material, such as a light absorbing resin; the light-absorbing material may be an inorganic light-absorbing material, such as light-absorbing metal titanium (Ti), and may be other light-absorbing materials, which may be selected according to actual needs, and is not particularly limited herein.
Optionally, in the display panel provided in the embodiment of the present invention, in order to avoid the problem of crosstalk existing before the adjacent sub-pixels, as shown in fig. 5, the display panel may further include: a light reflecting structure 6, the light reflecting structure 6 being located between adjacent light concentrating structures 4;
the light reflecting structure 6 is configured to reflect outgoing light at the gap between adjacent light concentrating structures 4.
Specifically, in the display panel provided in the embodiment of the present invention, as shown in fig. 4, the light shielding structure 5 is disposed between adjacent light collecting structures 4, so as to prevent the crosstalk phenomenon from occurring between adjacent sub-pixels 2 by absorbing light incident into the gap region. But the light absorbed by the light-shielding structure 5 is not utilized in the display. Based on this, as shown in fig. 5, the reflective structure 6 may be disposed at the gap of the light-collecting structure 4, and the light irradiated in the gap region may be reflected to the region where the corresponding sub-pixel 2 is located by the reflective structure 6, so that the light incident to the gap region may be utilized, and not only the crosstalk phenomenon between the adjacent sub-pixels 2 may be reduced, but also the luminance of the corresponding sub-pixel 2 may be further increased.
As shown in fig. 6, a top view of the display panel is provided with a light shielding structure 5 or a reflective structure 6 around the region where each sub-pixel 2 is located, and the light shielding structure 5 or the reflective structure 6 can be patterned by a single patterning process.
Optionally, in the display panel provided in the embodiment of the present invention, the material of the light reflecting structure includes a reflective metal.
The reflective metal may be specifically silver (Ag), aluminum (Al), molybdenum (Mo), or other reflective metals, which may be selected according to specific implementation and is not limited in this respect.
Wherein, the curve c in fig. 7 is a brightness curve corresponding to each angle when no light shielding structure or reflection structure is provided; the d1, d2, and d3 curves are luminance curves corresponding to respective angles when the reflective structure is Ag, Al, and Mo, respectively. As can be seen from fig. 7, when no light shielding structure or reflection structure is provided, there is crosstalk of large luminance in the viewing angle between 20 ° and 90 °, as shown by a curve c; when the reflection structure is arranged, only weak crosstalk exists between 50 degrees and 85 degrees, and compared with the crosstalk brightness value when the light shielding structure or the reflection structure is not arranged, the crosstalk brightness value can be ignored.
Optionally, in the display panel provided in the embodiment of the present invention, as shown in fig. 4 and 5, the display panel further includes: the packaging structure 3, the packaging structure 3 is located between the sub-pixel 2 and the light-gathering structure 4;
the thickness of the packaging structure 3 is 10% -60% of the focal length value of the light-gathering structure 4.
Specifically, in the display panel provided in the embodiment of the present invention, the light-condensing structure focuses light emitted by each sub-pixel to improve the brightness value of the corresponding sub-pixel, and the light-condensing structure has a focal length value, and when the distance between the light-emitting surface of the sub-pixel and the light-condensing structure is equal to the focal length value, the light-condensing effect of the light-condensing structure is the best, but a thicker film layer needs to be disposed between the light-emitting surface of the sub-pixel and the light-condensing structure, and the disposition of the thicker film layer not only increases the thickness of the display panel, but also increases the loss of light emitted by each sub-pixel, so that, when the distance between the light-emitting surface of the sub-pixel and the light-condensing structure is 10% to 60% of the focal length value, the display brightness of the display panel is better. The encapsulation structure between the sub-pixel and the light-condensing structure may be set to 10% to 60% of the focal value.
The specific thickness of the package structure may be selected according to the actual use condition, and is not limited herein.
Optionally, in the display panel provided in the embodiment of the present invention, the light-gathering structure may be a microlens structure having a light-gathering function. The microlens structure can have a light-condensing function by designing the radius of curvature and the crown of the microlens.
Optionally, in the display panel provided in the embodiment of the present invention, the sub-pixel may include: the electroluminescent device can emit light with the color corresponding to each sub-pixel, and can also be an electroluminescent device emitting white light.
The electroluminescence device has the advantages of self-luminescence, light weight and the like, can meet the requirement of easy carrying of an AR display device, focuses the brightness of the electroluminescence device through the arrangement of the light condensation structure, can also obviously improve the display brightness, makes up the light loss generated in the optical waveguide technology, and further meets the display brightness requirement of the display device.
Specifically, when the electroluminescent device is a white light emitting electroluminescent device, the display panel may further include a color film layer between the electroluminescent device and the light condensing structure to implement color display. Of course, a planarization layer is further included on the color film layer to facilitate formation of the light-focusing structure.

as shown in fig. 8a, a substrate 1 is provided, and an anode layer 21, a light emitting layer 22 and a cathode layer 23 are sequentially formed on the substrate 1, that is, a plurality of sub-pixels 2 are arranged in an array on the substrate 1;
in the display panel provided in the embodiment of the present invention, the structure of each sub-pixel is described by taking the anode layer as a bulk electrode and the cathode layer as a planar electrode as an example. The anode layer may be a planar electrode, and the cathode layer may be a bulk electrode, which may be selected according to actual needs, and is not particularly limited herein.
As shown in fig. 8b, the encapsulation structure 3 is formed on the side of the cathode layer 23 facing away from the substrate 1;
as shown in fig. 8c, a pattern of the reflective structure 6 is formed on the encapsulation structure 3;
