Description

Technical Field

[0001] The present invention relates to the field of display technology, and more particularly to a light-emitting panel and a display device. Background Art

[0002] With the advent of the ultra-high-definition display era, higher requirements are placed on display quality and resolution and other specifications. LED (Light-Emitting Diode) display technology shows better performance than LCD (Liquid Crystal Display) and OLED (Organic Light-Emitting Diode). Therefore, Mini LED or Micro LED technology has become the most promising new display technology in the display field. In addition, Mini LED or Micro LED technology can also realize the local dimming design of direct backlight to achieve a high dynamic range screen effect, making the picture more delicate, providing a high-brightness surface light source, and improving the overall module brightness. Therefore, it has become one of the research hotspots in the field of display technology.

[0003] In the prior art, although as many light sources as possible are arranged on the entire light-emitting panel for display or backlighting, it is still difficult for the light of the surface light source to enter the edge of the panel; and due to the influence of the diaphragm cutting process during the manufacturing process, water and oxygen are easily introduced into the edge of the diaphragm after long-term use, resulting in partial failure of the diaphragm function, which in turn easily causes the edge of the panel to darken, resulting in uneven brightness and other visual effects at the edge of the panel and other areas.

[0004] Therefore, providing a light-emitting panel and a display device that can improve the edge darkening phenomenon and enhance the light-emitting quality is a technical problem that needs to be solved urgently by those skilled in the art. Summary of the invention

[0005] In view of this, the present invention provides a light emitting panel and a display device to solve the problem in the prior art that the light emitting panel is easy to darken at the edge, resulting in uneven brightness compared with other positions.

[0006] The present invention discloses a light-emitting panel, comprising: a light-emitting area and a non-light-emitting area arranged around the light-emitting area; the light-emitting area comprises a first light-emitting area and at least one second light-emitting area, and along a direction parallel to a light-emitting surface of the light-emitting panel, the second light-emitting area is located on a side of the first light-emitting area close to the non-light-emitting area; the light-emitting panel of the first light-emitting area comprises at least a light source substrate and a plurality of optical films located on one side of the light source substrate, and along a direction perpendicular to the light-emitting surface of the light-emitting panel, the plurality of optical films are stacked and arranged; the light source substrate comprises a plurality of first light sources arranged in an array, and the light-emitting surfaces of the first light sources face the optical films; the light-emitting panel of the second light-emitting area comprises at least a second light source and a light guide strip, and a length extension direction of the light guide strip intersects with a direction from the first light-emitting area to the second light-emitting area; in the length extension direction of the light guide strip, the second light source and the light guide strip are adjacently arranged, and the light-emitting surface of the second light source faces the light guide strip.

[0007] Based on the same inventive concept, the present invention also discloses a display device, comprising the above-mentioned light-emitting panel.

[0008] Compared with the prior art, the light-emitting panel and display device provided by the present invention achieve at least the following beneficial effects:

[0009] The light-emitting panel provided by the present invention includes a light-emitting area and a non-light-emitting area arranged around the light-emitting area. The light-emitting area includes a first light-emitting area and at least one second light-emitting area. Along the direction parallel to the light-emitting surface of the light-emitting panel, the second light-emitting area is closer to the non-light-emitting area than the first light-emitting area. The non-light-emitting area can be understood as the edge area of ​​the light-emitting panel, and the second light-emitting area is a partial light-emitting area close to the edge area of ​​the light-emitting panel. The light-emitting panel of the first light-emitting area includes at least a light source substrate and a plurality of optical films located on one side of the light source substrate. The light-emitting surface of the first light source on the light source substrate faces the optical film, so that the plurality of first light sources form a surface light source of a direct-down structure in the first light-emitting area. The light-emitting panel of the second light-emitting area includes at least a second light source and a light guide bar arranged adjacent to each other. The light-emitting surface of the second light source faces the light guide bar, so that the second light source is a light source of a side-entry structure provided by the light guide bar. The light guide bar can guide the scattering direction of light emitted from the light-emitting surface of the second light source to improve the brightness of the second light-emitting area and improve the uniformity of the brightness of the second light-emitting area. The second light source and light guide strip provided in the present invention can compensate the luminance of the second luminous area, thereby making the brightness of the entire luminous area of ​​the luminous panel uniform, which can effectively improve the darkening phenomenon around the luminous panel and is beneficial to improving the overall luminous quality of the luminous panel.

[0010] Of course, any product implementing the present invention does not necessarily need to achieve all of the above-mentioned technical effects at the same time.

[0037] It should be noted that like reference numerals and letters refer to similar items in the following figures, and therefore, once an item is defined in one figure, it need not be further discussed in subsequent figures.

[0038] Please refer to Figure 1 and Figure 2 , Figure 1is a schematic diagram of a planar structure of a light-emitting panel provided by an embodiment of the present invention, Figure 2 yes Figure 1 A schematic diagram of the cross-sectional structure along the A-A' direction (it can be understood that in order to clearly illustrate the structure of this embodiment, Figure 1 The present embodiment provides a light-emitting panel 000, comprising: a light-emitting area AA and a non-light-emitting area NA arranged around the light-emitting area AA; the light-emitting area AA comprises a first light-emitting area AA1 and at least one second light-emitting area AA2, and along a direction parallel to a light-emitting surface of the light-emitting panel 000, the second light-emitting area AA2 is located on a side of the first light-emitting area AA1 close to the non-light-emitting area NA;

[0039] The light emitting panel 000 of the first light emitting area AA1 includes at least a light source substrate 10 ( Figure 1 Not indicated in Figure 2 The light source substrate 10 includes a plurality of optical films 20 located on one side of the light source substrate 10, and the plurality of optical films 20 are stacked along a direction Z perpendicular to the light emitting surface of the light emitting panel 000; the light source substrate 10 includes a plurality of first light sources 101 arranged in an array, and the light emitting surface 101E of the first light source 101 faces the optical film 20;

[0040] The light emitting panel 000 of the second light emitting area AA2 at least includes a second light source 30 and a light guide bar 40, the length extension direction X1 of the light guide bar 40 intersects with the direction Y1 from the first light emitting area AA1 to the second light emitting area AA2; in the length extension direction X1 of the light guide bar 40, the second light source 30 and the light guide bar 40 are arranged adjacent to each other, and the light emitting surface 30E of the second light source 30 faces the light guide bar 40. It can be understood that due to Figure 2 The section line shown in FIG. 1 does not cut to the second light source, and Figure 2 In order to clearly illustrate the location of the second light source, the second light source is indicated by a dotted line to indicate the relative relationship between the second light source and the light guide bar.

[0041] Specifically, the light-emitting panel 000 provided in the present embodiment may be a sub-millimeter light-emitting diode (Mini LED) or a micro light-emitting diode (Micro LED) light-emitting panel. The light-emitting panel 000 may include a light-emitting area AA and a non-light-emitting area NA arranged around the light-emitting area AA. Optionally, the light-emitting area AA may be provided with a plurality of light-emitting units to realize that the light-emitting panel 000 of the light-emitting area AA emits light on its light-emitting surface. The light-emitting area AA includes a first light-emitting area AA1 and at least one second light-emitting area AA2. Along a direction parallel to the light-emitting surface of the light-emitting panel 000, the second light-emitting area AA2 is located on a side of the first light-emitting area AA1 close to the non-light-emitting area NA, that is, the second light-emitting area AA2 is closer to the non-light-emitting area NA than the first light-emitting area AA1. The non-light-emitting area NA may be understood as the edge area of ​​the light-emitting panel 000, and the second light-emitting area AA2 is a partial light-emitting area close to the edge area of ​​the light-emitting panel 000. It can be understood that the light-emitting area of ​​the present embodiment Figure 1 The shapes and sizes of the first light-emitting area AA1 and the second light-emitting area AA2 are only exemplarily drawn, and do not represent the actual shapes and sizes during specific implementation, which can be set according to actual needs.

[0042] In this embodiment, the light-emitting panel 000 of the first light-emitting area AA1 includes at least a light source substrate 10 and a plurality of optical films 20 located on one side of the light source substrate 10. Optionally, the light source substrate 10 may include a substrate and a plurality of first light sources 101 arranged in an array on one side of the substrate, that is, the light source substrate 10 is used as a carrier substrate for the plurality of first light sources 101. The light source substrate 10 may also be provided with signal routings for driving the first light sources 101 to emit light. This is not illustrated in this embodiment, and specific reference may be made to the structure of the light source substrate in related technologies for understanding. Along the direction Z perpendicular to the light emitting surface of the light emitting panel 000, multiple optical films 20 are stacked and arranged, and the light emitting surface 101E of the first light source 101 faces the optical film 20. Optionally, the optical film 20 may include films with multiple functions. For example, the multiple optical films 20 may include a diffusion film that diffuses light and atomizes light, and may also include a brightening film that brightens the light, and may also include other optical films. This embodiment is not described in detail here, and it is only necessary to satisfy that the light emitting surface 101E of the first light source 101 faces the optical film 20, so that the multiple first light sources 101 form a surface light source with a direct-down structure in the first light emitting area AA1 of the light emitting panel 000. Optionally, a reflective film or a reflective coating (not shown in the figure) with a reflective function may be further arranged between adjacent first light sources 101 of the light source substrate 10 to improve light utilization efficiency through reflection; optionally, a plurality of first light sources 101 may be further covered with a protective layer to protect the first light sources 101 and prevent the optical film 20 from squeezing and damaging the first light sources 101. This embodiment is not specifically limited thereto, and specific reference may be made to the structure of the light source substrate of the light-emitting panel 000 in the related technology for understanding.

[0043] In this embodiment, the light-emitting panel 000 of the second light-emitting area AA2 at least includes a second light source 30 and a light guide bar 40, and the length extension direction X1 of the light guide bar 40 intersects with the direction Y1 from the first light-emitting area AA1 to the second light-emitting area AA2, that is, the light guide bar 40 is extended along the edge of the first light-emitting area AA1; optionally, the figure of this embodiment takes the example that the length extension direction X1 of the light guide bar 40 and the direction Y1 from the first light-emitting area AA1 to the second light-emitting area AA2 are perpendicular to each other. The second light source 30 and the light guide bar 40 are adjacently arranged in the length extension direction X1 of the light guide bar 40, and the light emitting surface 30E of the second light source 30 faces the light guide bar 40, so that the second light source 30 is a light source of a side-entry structure provided by the light guide bar 40, and the light guide bar 40 is used as a light guide plate of the second light source 20, and the light guide bar 40 can guide the scattering direction of the light emitted from the light emitting surface 30E of the second light source 30, so as to improve the brightness of the second light-emitting area AA2 and improve the uniformity of the brightness of the second light-emitting area AA2. The present embodiment does not limit the specific structure of the light guide bar 40, which can be understood by referring to the structure of the light guide plate with light guiding function in the related technology. It is only required that the emitted light of the second light source 30 can be uniformly emitted from the second light emitting area AA2 of the light emitting panel 000 after passing through the light guide bar 40, so that the second light emitting area AA2 can emit light uniformly.

[0044] Since the first light-emitting area AA1 in this embodiment includes multiple first light sources 101 arranged in an array and generally has a larger space, it is designed as a direct-down surface light source structure composed of at least multiple first light sources 101 and multiple stacked optical films 20. Since the second light-emitting area AA2 is generally located near the edge of the light-emitting panel 000 and has limited space, the light-emitting panel 000 of the second light-emitting area AA2 in this embodiment is designed as an edge-entry light source structure composed of at least a second light source 30 and a light guide strip 40 to compensate for the luminous brightness of a portion of the light-emitting area of ​​the light-emitting panel 000 close to the non-luminous area NA (edge ​​area), thereby making the brightness of the entire light-emitting area AA of the light-emitting panel 000 uniform, which can effectively improve the darkening phenomenon around the light-emitting panel 000, and is beneficial to improving the overall light-emitting quality of the light-emitting panel 000.

[0045] Optional, such as Figure 2 As shown, the structures of the light emitting panel 000 in this embodiment can be arranged in a frame 00 , and the frame 00 forms a receiving space for placing various structures in the light emitting panel 000 , and can also play a role in protecting various structures of the light emitting panel 000 .

[0046] Optionally, the second light-emitting area AA2 and the first light-emitting area AA1 in this embodiment can be controlled independently, that is, the first light source 101 and the second light source 30 can be controlled separately, and the light-emitting panel 000 can be connected to a detection circuit; further optionally, the detection circuit can be integrated in the driver chip, and the driver chip is bound to the light-emitting panel 000 to realize signal transmission. During the use of the light-emitting panel 000, when the detection circuit detects that the brightness of the second light-emitting area AA2 of the light-emitting panel 000 is significantly lower than the brightness of the first light-emitting area AA1 (or the brightness of the second light-emitting area AA2 is lower than a preset brightness value), the second light source 30 is turned on to compensate for the second light-emitting area AA2, so as to improve the overall light uniformity of the light-emitting panel 000. When the brightness difference between the second light-emitting area AA2 and the first light-emitting area AA1 is small, and the brightness difference is not enough to cause obvious visual effect defects, the second light source 30 can be turned off, which is conducive to saving panel power consumption.

[0047] Optionally, the light-emitting panel 000 of the first light-emitting area AA1 in the present embodiment may include a plurality of light-emitting units (or display units, not shown in the figure), and a light-emitting unit (or display unit) may include at least one first light source 101. Each light-emitting unit (or display unit) may be addressed and driven to light up individually. The light-emitting panel 000 of the present embodiment may reduce the pixel point distance from the millimeter level to the micron level, and is a self-luminous display, having the advantages of better material stability, longer life, and no image burn-in, etc.

[0048] Optionally, the light-emitting panel 000 provided in this embodiment can be used directly as a display panel, which is conducive to improving display uniformity and display effect through the setting of the second light-emitting area AA2. Or the light-emitting panel 000 provided in this embodiment can also be used as a backlight of a liquid crystal display panel, which is conducive to improving the overall light uniformity of the light-emitting panel 000 through the setting of the second light-emitting area AA2, thereby providing a uniform backlight for the liquid crystal display panel, which is conducive to improving the display effect. This embodiment does not specifically limit the use of the light-emitting panel 000. During specific implementation, the setting can be selected according to actual needs.

[0049] It should be noted that the figure of this embodiment only illustrates the structure of the light-emitting panel. When it is implemented, the structure of the light-emitting panel includes but is not limited to it, such as a protective layer located on one side of the light-emitting surface of the light-emitting panel 000 (not filled in the figure), and may also include other structures that can realize the display function. For example, when the first light source 101 is a blue light source, the optical film 20 of the light-emitting panel 000 may also include a color conversion layer such as a quantum dot film to realize the display of a full-color picture. For details, please refer to the structure of the Mini LED or Micro LED light-emitting panel in the relevant technology for understanding. This embodiment will not be described in detail here. The edge position of the quantum dot film used as the color conversion layer is prone to water and oxygen failure, resulting in blue edges. Therefore, the second light source 30 and the light guide bar 40 set in the second light-emitting area AA2 in this embodiment can also improve the blue edge phenomenon of the light-emitting panel 000, which is conducive to better improving the light quality. It should be further noted that the shape and size of the first light source 101 and the second light source 30 in the figure of this embodiment are only for illustration. When it is implemented, the size and shape of the first light source 101 and the second light source 30 can also be set according to actual needs, and this embodiment is not specifically limited.

[0050] In some alternative embodiments, please refer to Figure 3 , Figure 3 is another schematic diagram of the planar structure of the light-emitting panel provided by an embodiment of the present invention. In this embodiment, the light-emitting area AA includes a plurality of second light-emitting areas AA2, and the plurality of second light-emitting areas AA2 are arranged around the first light-emitting area AA1.

[0051] This embodiment explains that the light-emitting panel 000 may include a plurality of second light-emitting areas AA2, and the plurality of second light-emitting areas AA2 are respectively located at the peripheral edge positions of the light-emitting panel 000, that is, the plurality of second light-emitting areas AA2 may be arranged around the first light-emitting area AA1, so that the brightness of all edge areas of the light-emitting panel 000 close to the non-light-emitting area NA may be compensated, so as to better improve the uniformity of the light emission of the entire surface of the light-emitting panel 000 and further improve the light emission quality.

[0052] Optional, such as Figure 3As shown, in the present embodiment, one second light-emitting area AA2 corresponds to one light guide bar 40 and one second light source 30; the two second light sources 30 corresponding to two adjacent second light-emitting areas AA2 are not arranged adjacent to each other, that is, if one second light source 30 and one light guide bar 40 are understood as a group of structures, then one second light-emitting area AA2 corresponds to one group of the structure, and they are respectively located in two groups of the structure of different second light-emitting areas AA2, the two second light sources 30 are not arranged adjacent to each other, and the end of the light guide bar 40 of the first group of the structure is close to the second light source 30 in the second group of the structure, thereby avoiding the phenomenon of uneven brightness of some second light-emitting areas AA2 due to the aggregation of the second light sources 30. In the present embodiment, the multiple second light-emitting areas AA2 arranged around the first light-emitting area AA1 can have the same setting structure of each second light-emitting area AA2, that is, they all include the second light source 30 and the light guide bar 40, forming a side-entry light source structure, and uniformly fill in the multiple second light-emitting areas AA2 around the first light-emitting area AA1, so as to achieve a better improvement in the darkening effect around the light-emitting panel 000. It can be understood that in the present embodiment, Figure 3 The schematic structure can be applied to small and medium-sized light-emitting panels 000. Since the edge length of the small and medium-sized light-emitting panels 000 is relatively short, a second light-emitting area AA2 at the edge of one side of the light-emitting panel 000 can only correspond to one second light source 30 and a light guide strip 40, which can better achieve the effect of compensating the edge brightness.

[0053] Optional, please refer to Figure 4 , Figure 4 is another schematic diagram of the planar structure of the light-emitting panel provided by an embodiment of the present invention. In this embodiment, one second light-emitting area AA2 corresponds to two light guide strips 40 and two second light sources 30; in one second light-emitting area AA2, the two second light sources 30 are not arranged adjacent to each other. That is, if one second light source 30 and one light guide strip 40 are understood as a group of light source light guide structures, then one second light-emitting area AA2 corresponds to two groups of light source light guide structures, and in the two groups of light source light guide structures located in the same second light-emitting area AA2, the two second light sources 30 are not arranged adjacent to each other, such as Figure 4As shown, a second light-emitting area AA2 includes two groups of light source light-guiding structures, each group of light source light-guiding structures includes a light guide bar 40 and a second light source 30, the two light guide bars 40 of the two groups of light source light-guiding structures are arranged adjacent to each other, while the two second light sources 30 in the two groups of light source light-guiding structures are not arranged adjacent to each other and are respectively located at the two end positions of the two light guide bars 40, thereby avoiding the phenomenon that the brightness of part of the second light-emitting area AA2 is uneven due to the aggregation of the second light sources 30 in a second light-emitting area AA2. In this embodiment, the multiple second light-emitting areas AA2 arranged around the first light-emitting area AA1 can have the same setting structure, that is, each second light-emitting area AA2 can include two second light sources 30 and two light guide bars 40, forming a uniform side-entry light source structure, and uniformly supplementing the multiple second light-emitting areas AA2 around the first light-emitting area AA1, so as to achieve a better improvement in the darkening effect around the light-emitting panel 000. It can be understood that in this embodiment, Figure 4 The schematic structure can be applied to medium and large-sized light-emitting panels 000. Since the edge length of the medium and large-sized light-emitting panels 000 is longer, a second light-emitting area AA2 at the edge of one side of the light-emitting panel 000 can better achieve the effect of compensating the edge brightness by correspondingly setting two second light sources 30 and two light guide strips 40.

[0054] Optional, please refer to Figure 5 , Figure 5 1 is another schematic diagram of the planar structure of the light-emitting panel provided by an embodiment of the present invention. In this embodiment, one second light-emitting area AA2 corresponds to two light guide bars 40 and four second light sources 30; along the length extension direction X1 of the light guide bar 40, one second light source 30 is respectively arranged at both ends of one light guide bar 40. In this embodiment, two second light sources 30 and one light guide bar 40 are understood as a group of light source light guide structures, and the light emitting surfaces 30E of the two second light sources 30 in a group of the light source light guide structures are both oriented toward one light guide bar 40 in the group of the light source light guide structures, such as Figure 5As shown, if a group of the light source light guide structure includes a light guide bar 40 and a second light source 30A and a second light source 30B, then along the length extension direction X1 of the light guide bar 40, the second light source 30A and the second light source 30B are respectively arranged at the two ends of the light guide bar 40, and the light exit surface 30E of the second light source 30A faces the end of the light guide bar 40, and the light exit surface 30E of the second light source 30B also faces the end of the light guide bar 40, so that both ends of a light guide bar 40 can be provided with side-entry light sources (the light exit surface 30E of the second light source 30A), which is conducive to better uniform light emission of the light guide bar 40. In this embodiment, the multiple second light-emitting areas AA2 are arranged around the first light-emitting area AA1, and the arrangement structure of each second light-emitting area AA2 can be the same, that is, each second light-emitting area AA2 can include two light guide bars 40 and four second light sources 30, forming a uniform side-entry fill light structure around the first light-emitting area AA1, and uniformly filling light for the multiple second light-emitting areas AA2 around the first light-emitting area AA1, so as to achieve a better effect of improving the darkening of the periphery of the light-emitting panel 000. It can be understood that in this embodiment, Figure 5 The schematic structure can be applied to a large-sized or extra-large-sized light-emitting panel 000. Since the edge length of a large-sized or extra-large-sized light-emitting panel 000 is generally longer, a second light-emitting area AA2 at the edge of one side of the light-emitting panel 000 can correspond to two groups of light source light-guiding structures, and each group of light source light-guiding structures includes two second light sources 30 and one light guide bar 40, so that a second light-emitting area AA2 includes two light guide bars 40 and four second light sources 30, which can achieve better uniform compensation for edge brightness in the light-emitting panel 000 with a long side size.

[0055] It can be understood that Figure 3-Figure 5 In the embodiment, only the setting structure of the second light source 30 and the light guide strip 40 corresponding to the second light-emitting area AA2 is drawn for example. When it is implemented specifically, it includes but is not limited to the above-mentioned embodiment. It can also be specifically set according to the actual shape and actual size of the light-emitting panel 000 to achieve uniform fill light in the area close to the border around the first light-emitting area AA2. This embodiment will not be described in detail here.

[0056] Optionally, the plurality of second light-emitting areas AA2 around the first light-emitting area AA1 in this embodiment can be controlled independently, that is, the second light sources 30 in the plurality of second light-emitting areas AA2 can be controlled separately, and the light-emitting panel 000 can be connected with a detection circuit, which can be integrated in a driver chip and bound to the light-emitting panel 000 through the driver chip to realize signal transmission. During the use of the light-emitting panel 000, the real-time light-emitting condition of the light-emitting panel 000 can be detected by the detection circuit. When it is detected that the brightness of the area where one or more second light-emitting areas AA2 are located is dark and the brightness needs to be compensated to achieve the light amount that is as consistent as possible with the first light-emitting area AA1, the second light source 30 at the position is turned on for compensation. If the brightness of the second light-emitting areas AA2 at other positions has basically reached the brightness of the first light-emitting area AA1, the second light sources 30 in the second light-emitting areas AA2 at other positions can be temporarily turned off, so that the plurality of second light-emitting areas AA2 can be controlled according to different brightness requirements, which is conducive to saving panel power consumption and flexible control.

[0057] In some optional embodiments, please refer to Figure 6-Figure 8 , Figure 6 is another schematic diagram of a planar structure of a light emitting panel provided by an embodiment of the present invention, Figure 7 yes Figure 6 The schematic diagram of the structure of the second light source and the light guide strip, Figure 8 yes Figure 6 A schematic cross-sectional structure diagram along the B-B' direction (in order to clearly illustrate the structure of this embodiment, Figure 6 and Figure 7 Transparency filling is performed. Figure 7 In the embodiment, the light guide bar 40 includes a first side surface 40A and a first bottom surface 40B, and the first side surface 40A intersects with the first bottom surface 40B; along the direction Z perpendicular to the light emitting surface of the light emitting panel 000, the first bottom surface 40B is located on the side of the light guide bar 40 away from the light emitting surface of the light emitting panel 000; along the direction Y1 pointing from the first light emitting area AA1 to the second light emitting area AA2, the first side surface 40A is located on the side of the light guide bar 40 away from the first light emitting area AA1; the first side surface 40A includes a first reflective layer 501, and the first bottom surface 40B includes a second reflective layer 502.

[0058] This embodiment explains that the light guide strip 40 provided in the second light emitting area AA2 of the light emitting panel 000 can be formed into a plate with a smooth surface by means of injection molding by pressing acrylic, and then a material with high reflection and no light absorption is used to print diffusion points on the first bottom surface 40B of the light guide strip 40 by screen printing (not shown in the figure, the structure of the light guide plate in the related art can be specifically understood, and this embodiment will not be repeated here), wherein in the direction Z perpendicular to the light emitting surface of the light emitting panel 000, the first bottom surface 40B is located at the light guide strip 40 away from the light emitting surface of the light emitting panel 000 , and the light emitting surface 30E of the second light source 30 faces the end of the light guide bar 40. The light emitted by the second light source 30 is guided into the interior of the light guide bar 40 by reflection. When the light hits the diffusion point on the first bottom surface 40B of the light guide bar 40, the reflected light will diffuse to various angles, and then the reflection condition will be destroyed and emitted from the front side of the light guide bar 40 (i.e., the surface opposite to the first bottom surface 40B, facing the light emitting surface direction of the light emitting panel 000). The light guide bar 40 can make use of various diffusion points of different densities and sizes made on the first bottom surface 40B to make the light guide bar 40 emit light uniformly. In this embodiment, a second reflection layer 502 is set on the first bottom surface 40B. Optionally, the second reflection layer 502 can be formed by silver plating by a coating process. The purpose of the second reflection layer 502 is to reflect the light emitted from the second light source 30 to the first bottom surface 40B back into the interior of the light guide bar 40 to improve the efficiency of light use. The light guide bar 40 of the present embodiment includes a first side surface 40A, which intersects with the first bottom surface 40B and is in the direction Y1 from the first light-emitting area AA1 to the second light-emitting area AA2. The first side surface 40A is located on the side of the light guide bar 40 away from the first light-emitting area AA1. A first reflective layer 501 is provided on the first side surface 40A. Optionally, the first reflective layer 501 can be formed by silver plating using a coating process. The purpose of the first reflective layer 501 is to further reflect the light emitted from the second light source 30 to the first side surface 40A back into the interior of the light guide bar 40, and further diffuse it to various angles inside the light guide bar 40, destroying the reflection condition and emitting light uniformly from the front side of the light guide bar 40 (i.e., the surface opposite to the first bottom surface 40B), thereby further improving the use efficiency of light, which is beneficial to improving the luminous brightness of the second light-emitting area AA2 and improving the light extraction efficiency.

[0059] In some optional embodiments, please refer to Figure 6 , Fig. 9 and Fig.10 , Fig. 9 yes Figure 6 Another structural schematic diagram of the second light source and the light guide strip, Fig.10 yes Figure 6 Another cross-sectional structural schematic diagram along the BB' direction (in order to clearly illustrate the structure of this embodiment, Fig. 9Transparency filling is performed), in this embodiment, the angle α formed by the intersection of the first side surface 40A and the first bottom surface 40B of the light guide strip 40 is less than 90 degrees.

[0060] This embodiment explains that the light guide bar 40 includes a first side surface 40A and a first bottom surface 40B, wherein in the direction Z perpendicular to the light emitting surface of the light emitting panel 000, the first bottom surface 40B is located on the side of the light guide bar 40 away from the light emitting surface of the light emitting panel 000, and in the direction Y1 from the first light emitting area AA1 to the second light emitting area AA2, the first side surface 40A is located on the side of the light guide bar 40 away from the first light emitting area AA1, the first side surface 40A is provided with a first reflection layer 501, and the first bottom surface 40B is provided with a second reflection layer 502, and the angle α formed by the intersecting first side surface 40A and the first bottom surface 40B is less than 90 degrees, so that the angle α formed by the first side surface 40A away from the first light emitting area AA1 and the first bottom surface 40B away from the light emitting surface of the light emitting panel 000 can be set to be an acute angle, and the light reflected from the first bottom surface 40B can be reused, such as Fig.10 As shown, if the light L entering the light guide strip 40 is reflected from the first bottom surface 40B, since the angle α formed by the intersection of the first side surface 40A and the first bottom surface 40B is less than 90 degrees, the light L can be further reflected to the first side surface 40A, and then emitted from the front side of the light guide strip 40 (i.e., in the direction toward the light emitting surface of the light emitting panel 000), which is conducive to more effective use of light and improved light output brightness.

[0061] In some optional embodiments, please refer to Figure 6 , Fig.11 and Fig.12 , Fig.11 yes Figure 6 Another structural schematic diagram of the second light source and the light guide strip, Fig.12 yes Figure 6 Another cross-sectional structural schematic diagram along the BB' direction (in order to clearly illustrate the structure of this embodiment, Fig.11 Transparency filling is performed), in this embodiment, the light guide bar 40 includes a first portion 401 and a second portion 402, along a direction Y1 pointing from the first light-emitting area AA1 to the second light-emitting area AA2, and the first portion 401 is located on a side of the second portion 402 close to the first light-emitting area AA1; wherein, in a direction Z perpendicular to the light-emitting surface of the light-emitting panel 000, a thickness D1 of the first portion 401 is less than a thickness D2 of the second portion 402.

[0062] This embodiment explains that the shape of the light guide bar 40 may include Figure 7 and Fig. 9The schematic strip structure, or light guide bar 40, includes a first portion 401 and a second portion 402, wherein the first portion 401 and the second portion 402 may be an integrally formed structure, and in this embodiment, they are named as the first portion 401 and the second portion 402 only for the convenience of describing the structures of different regions of the light guide bar 40. Along the direction Y1 from the first light-emitting area AA1 to the second light-emitting area AA2, the first portion 401 is located on a side of the second portion 402 close to the first light-emitting area AA1, and the first portion 401 is closer to the first light-emitting area AA1 than the second portion 402. In this embodiment, in the direction Z perpendicular to the light emitting surface of the light emitting panel 000, the thickness D1 of the first part 401 is less than the thickness D2 of the second part 402, that is, the light guide strip 40 includes two parts with different thicknesses, which are integrally formed, wherein the thickness D1 of the first part 401 closer to the first light emitting area AA1 is smaller, and the thickness D2 of the second part 402 away from the first light emitting area AA1 is larger. Optionally, in the direction Z perpendicular to the light emitting surface of the light emitting panel 000, the thickness D1 of the first part 401 is equal, and the thickness D2 of the second part 402 is equal, which can be formed as follows Fig.11 The longitudinal cross-section of the light guide strip 40 shown is an inverted L-shaped structure, so that the surface of the light guide strip 40 on the side facing the light emitting surface of the light-emitting panel 000 can be larger. The light emitted from the first light source 30 to the inside of the light guide strip 40 can be reflected from the first bottom surface 40B with a smaller area to the front side of the light guide strip 40 with a larger area. That is, the light emitting surface corresponding to the second light emitting area AA2 can be made wider, which is beneficial to further uniformize the light emitting effect of the second light emitting area AA2.

[0063] It can be understood that the figure of this embodiment is only an example of the shape that the light guide strip 40 can be designed to be when the thickness D1 of the first part 401 is less than the thickness D2 of the second part 402 in the direction Z perpendicular to the light emitting surface of the light-emitting panel 000. In specific implementations, the shape of the light guide strip 40 includes but is not limited to this, and can also be other design structures, which is not limited to this in this embodiment.

[0064] In some optional embodiments, please refer to Figure 6 and Fig.13 , Fig.13 yes Figure 6 Another structural schematic diagram of the second light source and the light guide strip (in order to clearly illustrate the structure of this embodiment, Fig.13 Transparency filling is performed), in this embodiment, in the direction Z perpendicular to the light emitting surface of the light emitting panel 000, the surface 30C of the second light source 30 facing the light emitting surface of the light emitting panel 000 is flush with the surface 40C of the light guide bar 40 facing the light emitting surface of the light emitting panel 000.

[0065] This embodiment explains that in the direction Z perpendicular to the light emitting surface of the light-emitting panel 000, the second light source 30 can be at the same height as the light guide bar 40, and optionally the surface 30C of the second light source 30 facing the light emitting surface of the light-emitting panel 000 and the surface 40C of the light guide bar 40 facing the light emitting surface of the light-emitting panel 000 can be arranged and flush, so that the end of the light guide bar 40 facing the second light source 30 can allow as much light as possible to enter the light emitting surface 30E of the second light source 30, so that the amount of light in the entire light guide bar 40 is as large as possible, which is beneficial to improving the light utilization rate of the second light source 30, and further improving the light output brightness of the second light-emitting area AA2.

[0066] In some optional embodiments, please refer to Figure 6 , Fig.14 and Fig.15 , Fig.14 yes Figure 6 Another structural schematic diagram of the second light source and the light guide strip, Fig.15 yes Figure 6 Another cross-sectional structural schematic diagram along the BB' direction (in order to clearly illustrate the structure of this embodiment, Fig.14 Transparency filling is performed), in this embodiment, in the direction Z perpendicular to the light emitting surface of the light emitting panel 000, the surface 40C of the light guide strip 40 facing the light emitting surface of the light emitting panel 000 is higher than the surface 30C of the second light source 30 facing the light emitting surface of the light emitting panel 000.

[0067] This embodiment explains that in the direction Z perpendicular to the light emitting surface of the light-emitting panel 000, the heights of the second light source 30 and the light guide bar 40 may not be equal, and optionally, a surface 40C of the light guide bar 40 facing the light emitting surface of the light-emitting panel 000 is higher than a surface 30C of the second light source 30 facing the light emitting surface of the light-emitting panel 000, that is, the height of the second light source 30 is slightly lower than the height of the light guide bar 40, so that the light emitted from the light emitting surface 30E of the second light source 30 can fully enter the interior of the light guide bar 40 from all directions and angles, thereby preventing the light of the second light source 30 from being exposed to a position other than the light guide bar 40, causing light waste, and thereby improving the light output brightness of the second light-emitting area AA2.

[0068] Optional, such as Fig.14 and Fig.15As shown, when in the direction Z perpendicular to the light emitting surface of the light-emitting panel 000, the heights of the second light source 30 and the light guide strip 40 are not equal, and the surface 40C of the light guide strip 40 facing the light emitting surface of the light-emitting panel 000 is higher than the surface 30C of the second light source 30 facing the light emitting surface of the light-emitting panel 000, along the direction Y1 from the first light-emitting area AA1 to the second light-emitting area AA2, the thickness D1 of the first part 401 in the direction Z perpendicular to the light emitting surface of the light-emitting panel 000 gradually increases; the thickness D2 of the second part 402 in the direction Z perpendicular to the light emitting surface of the light-emitting panel 000 is equal; the first part 401 includes a first inclined surface 401A facing the first light-emitting area AA1, and the first inclined surface 401A includes a third reflective layer 503.

[0069] This embodiment explains that when the surface 40C of the light guide bar 40 facing the light emitting surface of the light emitting panel 000 is higher than the surface 30C of the second light source 30 facing the light emitting surface of the light emitting panel 000, that is, the second light source 30 may be shorter due to the limitation of its own process or technology, it can be set along the direction Y1 pointing from the first light emitting area AA1 to the second light emitting area AA2, and the thickness D1 of the first part 401 in the direction Z perpendicular to the light emitting surface of the light emitting panel 000 gradually increases, that is, the side surface of the first part 401 facing the first light emitting area AA1 forms a first inclined surface 401A. Since the height of the second light source 30 is less than the height of the light guide bar 40, when the light of the second light source 30 is emitted from its light emitting surface 30E to the light guide bar 4 0 and enters the interior of the light guide bar 40, the light in the upper half of the light guide bar 40 (i.e., the portion relatively close to the light emitting surface of the light emitting panel 000) will be relatively less. Therefore, the present embodiment is arranged along the direction Y1 pointing from the first light emitting area AA1 to the second light emitting area AA2, and the thickness D1 of the first portion 401 in the direction Z perpendicular to the light emitting surface of the light emitting panel 000 gradually increases to form a first inclined surface 401A inclined toward the light emitting surface of the light emitting panel 000, and the volume of the upper half of the light guide bar 40 is reduced as much as possible to supplement the light in the upper half of the light guide bar 40, so that the light emitted from the light guide bar 40 can be made as uniform as possible, thereby improving the light emitting quality of the second light emitting area AA2.

[0070] Optional, such as Fig.15 As shown, in this embodiment, a third reflective layer 503 is further arranged on the first inclined surface 401A. The third reflective layer 503 can be formed by silver plating using a coating process, so that the light L emitted to the first inclined surface 401A can be further reflected back to the range where the second light-emitting area AA2 is located as much as possible through the third reflective layer 503, thereby avoiding the problem of light crosstalk between the two areas caused by the light L of the second light-emitting area AA2 leaking to the first light-emitting area AA1, which is beneficial to ensuring the light output effect of the first light-emitting area AA1.

[0071] In some optional embodiments, please refer to Figure 6 , Fig.16 and Fig.17 , Fig.16 yes Figure 6 Another structural schematic diagram of the second light source and the light guide strip, Fig.17 yes Fig.16 Schematic diagram of the side view structure of the middle light guide strip (in order to clearly illustrate the structure of this embodiment, Fig.16 Transparency filling is performed), in this embodiment, along the length extension direction X1 of the light guide bar 40, the light guide bar 40 includes a first end 40X close to the second light source 30 and a second end 40Y away from the second light source 30; along the direction from the first end 40X to the second end 40Y, the thickness D3 of the light guide bar 40 in the direction Z perpendicular to the light emitting surface of the light-emitting panel 000 gradually decreases.

[0072] This embodiment explains that the thickness D3 of the light guide strip 40 in the direction Z perpendicular to the light emitting surface of the light emitting panel 000 shows a gradual trend. Specifically, along the length extension direction X1 of the light guide strip 40, the light guide strip 40 includes a first end 40X close to the second light source 30 and a second end 40Y away from the second light source 30. Along the direction from the first end 40X to the second end 40Y, the thickness D3 of the light guide strip 40 in the direction Z perpendicular to the light emitting surface of the light emitting panel 000 gradually decreases, that is, the thickness D3 of the light guide strip 40 on the side close to the second light source 30 is larger, and the thickness D3 of the light guide strip 40 on the side away from the second light source 30 is smaller. Some, thereby making the thickness of the light guide strip 40 smaller the further away from the second light source 30, and then through the coordinated setting of the second reflective layer 502 on the first bottom surface 40B, the thickness D3 of the light guide strip 40 on the side farther away from the second light source 30 is reduced, which is beneficial for making the light reflected from the first bottom surface 40B inside the light guide strip 40 to be able to be more evenly emitted from the light guide strip 40 toward the surface 40C on the light emitting surface side of the light-emitting panel 000, and can avoid the situation where the light output brightness on the side close to the second end 40Y is low due to the second end 40Y being far away from the second light source 30, which is beneficial for ensuring the light output uniformity of the entire second light-emitting area AA2.

[0073] Optional, such as Fig.17As shown, the light guide strip 40 includes a first bottom surface 40B. In the direction Z perpendicular to the light emitting surface of the light emitting panel 000, the first bottom surface 40B is located on the side of the light guide strip 40 away from the light emitting surface of the light emitting panel 000; the angle β formed by the first bottom surface 40B and the light emitting surface of the light emitting panel 000 (which can be understood as a horizontal plane S indicated by a dotted line in the figure) is less than 45 degrees. The present embodiment explains that the thickness D3 of the light guide strip 40 in the direction Z perpendicular to the light emitting surface of the light emitting panel 000 shows a gradual trend, that is, the first bottom surface 40B of the light guide strip 40 can be in an upwardly tilted and warped structure, so as to avoid the situation where the light output brightness on the side close to the second end 40Y is low due to the second end 40Y being far away from the second light source 30. The angle β formed by the first bottom surface 40B and the light emitting surface of the light emitting panel 000 can be further set to be less than 45 degrees, that is, the upwardly tilted angle range of the first bottom surface 40B is within 45 degrees, so as to avoid the light guide strip 40 at the second end 40Y far away from the second light source 30 being too thin, which may easily cause the light reflection space inside the light guide strip 40 to be reduced and affect the light guiding effect, thereby helping to better improve the light output quality of the second light emitting area AA2.

[0074] In some optional embodiments, please continue to refer to Figure 6-Figure 17 In this embodiment, the optical film 20 at least covers the first light source 101 in the first light emitting area AA1.

[0075] This embodiment explains that the multiple optical films 20 in the light-emitting panel 000, which are located on the side of the light source substrate 10 facing the light-emitting surface of the light-emitting panel 000, can at least cover the multiple first light sources 101 in the first light-emitting area AA1, that is, within the first light-emitting area AA1 of the direct-down light source structure, the orthographic projection of the optical film 20 on the light-emitting surface of the light-emitting panel 000 is at least located within the range of the first light-emitting area AA1, so that the first light-emitting area AA1 where the multiple first light sources 101 are located can form a surface light source of a direct-down structure by means of the optical film 20 having multiple functions, such as a diffusion film for diffusing and atomizing light and a brightness enhancement film for brightening light, thereby improving the light emission effect of the first light-emitting area AA1 of the light-emitting panel 000 as much as possible.

[0076] Optional, please continue to combine reference Fig.18 and Fig.19 , Fig.18 is another schematic diagram of a planar structure of a light emitting panel provided by an embodiment of the present invention, Fig.19 yes Fig.18 A schematic diagram of the cross-sectional structure along the C-C' direction (in order to clearly illustrate the structure of this embodiment, Fig.18Transparency filling is performed), in this embodiment, the optical film 20 includes a first sub-portion 201 and a second sub-portion 202, the first sub-portion 201 covers the first light source 101 of the first light-emitting area AA1, and the second sub-portion 202 covers the light guide bar 40 of the second light-emitting area AA2.

[0077] This embodiment explains that the light-emitting panel 000 sets a second light-emitting area AA2 around the first light-emitting area AA1 for edge fill light, and the optical film 20 in the first light-emitting area AA1 can be appropriately extended. Specifically, the optical film 20 may include an integrally formed first sub-portion 201 and a second sub-portion 202. The first sub-portion 201 covers the first light source 101 of the first light-emitting area AA1. The first sub-portion 201 of the optical film 20 can dim the outgoing light in the first light-emitting area AA1 to meet the requirements of brightness and uniformity. The second sub-portion 202 covers the light guide bar 40 of the second light-emitting area AA2. The second sub-portion 202 of the optical film 20 can further extend to above the light guide bar 40 of the second light-emitting area AA2, so as to further dim the light emitted from the light guide bar 40, so that the light output of the first light-emitting area AA1 and the second light-emitting area AA2, that is, the light output surface of the entire light-emitting panel 000, is more uniform, which is beneficial to improving the light output quality of the entire light-emitting panel 000.

[0078] In some alternative embodiments, please refer to Fig. 20 , Fig. 20 1 is a schematic diagram of the planar structure of a display device provided in an embodiment of the present invention. The display device 111 provided in this embodiment includes the light-emitting panel 000 provided in the above embodiment of the present invention. Optionally, the display device 111 may be the light-emitting panel 000 in the above embodiment of the present invention, and directly displays. Alternatively, the display device 111 may also be a liquid crystal display device, in which case the light-emitting panel 000 of this embodiment may be used as a direct-type backlight. This embodiment does not specifically limit the type of the display device 111, and it may be set according to actual needs during specific implementation. Fig. 20 The embodiment only takes a mobile phone as an example to illustrate the display device 111. It can be understood that the display device 111 provided in the embodiment of the present invention can be a computer, a television, a car display device or other display device 111 with a display function, and the present invention does not specifically limit this. The display device 111 provided in the embodiment of the present invention has the beneficial effects of the light-emitting panel 000 provided in the embodiment of the present invention. For details, please refer to the specific description of the light-emitting panel 000 in the above embodiments, and this embodiment will not be repeated here.

[0079] It can be seen from the above embodiments that the light-emitting panel and the display device provided by the present invention achieve at least the following beneficial effects:

[0080] The light-emitting panel provided by the present invention includes a light-emitting area and a non-light-emitting area arranged around the light-emitting area. The light-emitting area includes a first light-emitting area and at least one second light-emitting area. Along the direction parallel to the light-emitting surface of the light-emitting panel, the second light-emitting area is closer to the non-light-emitting area than the first light-emitting area. The non-light-emitting area can be understood as the edge area of ​​the light-emitting panel, and the second light-emitting area is a partial light-emitting area close to the edge area of ​​the light-emitting panel. The light-emitting panel of the first light-emitting area includes at least a light source substrate and a plurality of optical films located on one side of the light source substrate. The light-emitting surface of the first light source on the light source substrate faces the optical film, so that the plurality of first light sources form a surface light source of a direct-down structure in the first light-emitting area. The light-emitting panel of the second light-emitting area includes at least a second light source and a light guide bar arranged adjacent to each other. The light-emitting surface of the second light source faces the light guide bar, so that the second light source is a light source of a side-entry structure provided by the light guide bar. The light guide bar can guide the scattering direction of light emitted from the light-emitting surface of the second light source to improve the brightness of the second light-emitting area and improve the uniformity of the brightness of the second light-emitting area. The second light source and light guide strip provided in the present invention can compensate the luminance of the second luminous area, thereby making the brightness of the entire luminous area of ​​the luminous panel uniform, which can effectively improve the darkening phenomenon around the luminous panel and is beneficial to improving the overall luminous quality of the luminous panel.
