Thus, the present application is not intended to be limited to the embodiments shown, but is to be accorded the widest scope consistent with the principles and features disclosed herein.

In the related art, light emitted by a light emitting device of a display device based on the Mini-LED technology is easy to escape and consume, so that the light utilization rate is low, and the problems of high power consumption, low energy efficiency and poor power saving performance are caused when required display brightness is realized.

As shown in fig. 1, the present embodiment provides a display structure 1, where the display structure 1 includes a substrate 10, a plurality of barriers 20, a light emitting device 40, and a reflective layer 50, and can reduce power consumption in use, and improve energy efficiency ratio and power saving performance.

Here, the type of the substrate 10 may be determined according to actual needs, and a type such as a glass substrate, a flexible substrate, and the like may be used, which is not limited in this embodiment. The retaining walls 20 are respectively disposed on the substrate 10, and the light emitting holes 30 are formed between adjacent retaining walls 20. Here, the dam 20 may be formed on the substrate 10 by a manufacturing method such as deposition etching, additive manufacturing, inkjet printing, and the like, using an organic material.

The light emitting device 40 is disposed on the substrate 10, and the light emitting device 40 is located in the light exit hole 30. Thus, the light emitted from the light emitting device 40 can be emitted through the light exit hole 30. Here, the light emitting device 40 and the peripheral wall of the light exit hole 30 have a gap therebetween in a gap-fitting relationship. The type of the light emitting device 40 may be determined according to actual needs, and may be a light emitting diode type such as Micro-LED, Mini-LED, etc., which is not limited in this embodiment.

The reflective layers 50 are respectively disposed on the peripheral wall of the light exit hole 30 and the region of the substrate 10 between the peripheral wall of the light exit hole 30 and the light emitting device 40. Here, the reflective layer 50 may include a side reflective layer 51 and a bottom reflective layer 52, which have high reflectivity to light emitted from the light emitting device 40 and may reflect the light. The side reflective layer 51 is disposed on the peripheral wall of the light exit hole 30, i.e., on the side surface of the retaining wall 20 surrounding the light exit hole 30. The bottom reflective layer 52 is disposed on the substrate 10 in a region between the peripheral wall of the light exit hole 30 and the light emitting device 40, and covers the region between the peripheral wall of the light exit hole 30 and the light emitting device 40 to prevent light from escaping from the region.

Among the light emitted from the light emitting device 40 at different angles, the light emitted at a part of the angles can be directly emitted out of the display structure 1 along the light exit hole 30 for displaying, and the light emitted at the other angles can be irradiated onto the reflective layer 50, reflected by the reflective layer 50, and then emitted out of the display structure 1 along the light exit hole 30 for displaying. In this way, all or at least most of the light emitted by the light emitting device 40 can be emitted and displayed along the light exit hole 30 in a concentrated manner, and the utilization rate of the light emitted by the light emitting device 40 is increased to meet the requirement of display brightness. Compared with the related art, the display structure 1 provided by the embodiment of the application has higher light utilization rate, can achieve the required display brightness at a lower power consumption level, correspondingly reduces the use power consumption and the power consumption, and improves the energy efficiency ratio and the power saving performance of the display equipment based on the Mini-LED technology and the like.

In some embodiments, the display structure 1 may further include a color conversion layer 60. The color conversion layer 60 is disposed corresponding to the at least one light exit hole 30, and the color conversion layer 60 is configured to perform color conversion on the light exiting from the light exit hole 30. In some examples, the color conversion layer 60 may be provided only for some of the light exit holes 30, and the color conversion layer 60 may not be provided for the remaining light exit holes 30; in other examples, the color conversion layer 60 may be provided for all of the light exit holes 30. The material of the color conversion layer 60 may be determined according to actual needs, and may be a type such as a fluorescent material or a composite material containing a fluorescent component, which is not limited in the embodiment of the present application.

In some examples, when the light emitting device 40 corresponding to the red sub-pixel is a blue Mini-LED or an ultraviolet Mini-LED, the corresponding color conversion layer 60 may convert the blue light emitted by the blue Mini-LED or the near ultraviolet light emitted by the ultraviolet Mini-LED into red light, so as to implement red light display; when the light emitting device 40 corresponding to the green sub-pixel is a blue Mini-LED or an ultraviolet Mini-LED, the corresponding color conversion layer 60 may convert the blue light emitted by the blue Mini-LED or the near ultraviolet light emitted by the ultraviolet Mini-LED into green light, thereby implementing green light display; when the light emitting device 40 corresponding to the blue sub-pixel is an ultraviolet Mini-LED, the corresponding color conversion layer 60 may convert near ultraviolet light emitted from the ultraviolet Mini-LED into blue light, so as to implement blue light display. Thus, only the blue Mini-LED or the ultraviolet Mini-LED can be used as the light emitting device 40, so that the red Mini-LED with high manufacturing difficulty and cost and the green Mini-LED with color deflection under low current are avoided, the cost of the display structure 1 is reduced, and the color stability of the display structure 1 is improved.

In some examples, the display structure 1 may further include a transmissive layer 70, the transmissive layer 70 and the at least one light exit hole 30 being disposed correspondingly; any light hole 30 is only provided corresponding to one of the color conversion layer 60 and the transmission layer 70, so that the color conversion layer 60 and the transmission layer 70 are arranged on the light-emitting surface of the display structure 1 in a staggered manner. Here, the transmissive layer 70 may employ a transparent color resist material containing diffusion particles, such as transparent silicon dioxide, in which a fluorescent material is not doped, and transmits only light without converting the color of the light. For the light exit holes 30 for which the color conversion layer 60 has been disposed accordingly, the transmissive layer 70 is no longer disposed; for the light exit holes 30 where the color conversion layer 60 is not correspondingly disposed, the transmissive layer 70 may be correspondingly disposed; for the light exit holes 30 for which the transmissive layer 70 has been arranged accordingly, the color conversion layer 60 is no longer arranged. Here, when the light emitting device 40 corresponding to the blue sub-pixel is a blue Mini-LED, the transmission layer 70 may transmit the blue light and still output the blue light, so that the luminance of the output blue light is relatively close to the luminance of the red light and the green light output by the red and green sub-pixels, the luminance difference of different sub-pixels is reduced, the display uniformity of different sub-pixels is increased, and the display effect of the display structure 1 is improved.

The hierarchical structure of the color conversion layer 60 and the transmission layer 70 can be determined according to actual needs, so as to satisfy the display uniformity of different sub-pixels, which is not limited in the embodiment of the present application. For example, the color conversion layer 60 and the transmission layer 70 can be disposed in the same layer, so that the incident/emergent light positions of the color conversion layer 60 and the transmission layer 70 are equivalent, and the synchronization and consistency of the emergent lights with different colors are increased.

The relative arrangement positions of the transmission layer 70 and the light exit hole 30 can be determined according to actual needs, and the embodiment of the present application does not limit this. For example, the transmissive layer 70 may be filled in the light outlet hole 30 and cover at least a light emitting surface of the light emitting device 40. As another example, the transmissive layer 70 may be disposed on a side of the retaining wall 20 away from the substrate 10.

The relative positions of the color conversion layer 60 and the light exit hole 30 can be determined according to actual needs, and the embodiment of the present application does not limit this. In some examples, the color conversion layer 60 may fill in the light exit hole 30 and cover at least the light emitting surface of the light emitting device 40. As another example, the color conversion layer 60 may be disposed on a side of the blocking wall 20 away from the substrate 10.

The arrangement form of the retaining walls 20 can be determined according to actual needs, and the embodiment of the present application is not limited to this. In some embodiments, the retaining walls 20 may be disposed in parallel at intervals to form a uniform arrangement of the light emitting holes 30, so as to satisfy the requirement of better display effect.

The color of the retaining wall 20 can be determined according to actual needs, and the embodiment of the present application is not limited thereto. In some embodiments, the retaining wall 20 may be made of a black material, which has a better light-shielding effect, and can increase the black degree of the front viewing angle of the display structure 1, reduce crosstalk between lights with different colors, and accordingly increase the display contrast and color stability of the display structure 1. The configuration of the retaining wall 20 can be determined according to actual needs, and the embodiment of the present application is not limited thereto. In some embodiments, the end of the dam 20 away from the substrate 10 may have an ellipsoidal end structure, which may reduce the size range of the black matrix and the area of the non-display region, and increase the ratio of the display region.

In some embodiments, the display structure 1 may further include a light shielding layer 80, and the light shielding layer 80 is disposed on the surface of the retaining wall 20 away from the substrate 10. By using the light shielding layer 80, the black degree of the front viewing angle of the display structure 1 can be increased, the crosstalk between different color lights can be reduced, and the display contrast and the color stability of the display structure 1 can be correspondingly increased. In some examples, the light shielding layer 80 may be connected to the reflective layer 50, and the side surfaces of the retaining wall 20 are covered by the light shielding layer and the reflective layer.

The embodiment of the present application provides a display device, which includes the display structure 1 of any one of the above embodiments. The type of the display device may be determined according to actual needs, and may be a type such as a laser projector, a flat panel television, a display, and the like, which is not limited in the embodiments of the present application. Accordingly, the display device may include a corresponding structure of a corresponding device type, which is not described herein again.
