[0026] Figure 1This is a schematic diagram of the first embodiment of the display panel of this application, as shown below. Figure 1 As shown in the figure, this application discloses a display panel 100, including a substrate 110, on which isolation layers 120 are spaced apart, and a light-emitting layer 130 is disposed between two adjacent isolation layers 120. Electrode layers 140 are disposed on the light-emitting layer 130 and the isolation layers 120. The display panel 100 also includes a light-absorbing layer 150, which is disposed opposite to the electrode layers 140. A plurality of reflective elements 160 are disposed between the light-absorbing layer 150 and the electrode layers 140. Each reflective element 160 corresponds to an isolation layer 120. The position of 20 is set; a light-emitting area 180 is formed between two adjacent reflectors 160; the light-absorbing layer 150 includes a first light-absorbing layer 151 and a second light-absorbing layer 152, the first light-absorbing layer 151 and the second light-absorbing layer 152 are set corresponding to the light-emitting area 180; the light absorption axes of the first light-absorbing layer 151 and the second light-absorbing layer 152 are different; the reflector 160 is used to reflect the external light transmitted through the first light-absorbing layer 151 to the second light-absorbing layer 152, or to reflect the external light transmitted through the second light-absorbing layer 152 to the first light-absorbing layer 151.

[0027] The application sets the reflecting member 160 and the light-absorbing layer 150 with different light-absorbing axes in the display panel 100. When the external light irradiates the display panel 100 from the side of the first light-absorbing layer 151, the first light-absorbing layer 151 will first absorb part of the external light, and the external light that transmits through the first light-absorbing layer 151 will irradiate the reflecting member 160 in the display panel 100, the reflecting member 160 reflects the light to the second light-absorbing layer 152, and the second light-absorbing layer 152 will absorb part of the light that irradiates into the display panel 100 again, and finally a small part of the light is emitted out of the display panel 100. Because the light-absorbing axes of the first light-absorbing layer 151 and the second light-absorbing layer 152 are different, the second light-absorbing layer 152 and the first light-absorbing layer 151 absorb light with different polarization angles, respectively. When the external light irradiates the display panel 100 from the side of the second light-absorbing layer 152, the second light-absorbing layer 152 will first absorb part of the external light, and the external light that transmits through the second light-absorbing layer 152 will irradiate the reflecting member 160 in the display panel 100, and then the reflecting member 160 reflects the light to the first light-absorbing layer 151, and the first light-absorbing layer 151 will absorb part of the light that irradiates into the display panel 100 again, and finally a small part of the light is emitted out of the display panel 100. That is, the application uses the first light-absorbing layer 151 or the second light-absorbing layer 152 to absorb the external light for the first time when the external light irradiates, and then uses the reflecting member 160 to adjust the irradiation path of the external light that transmits through the first light-absorbing layer 151 or the second light-absorbing layer 152, so that the first light-absorbing layer 151 or the second light-absorbing layer 152 forms the second absorption of the external light, thereby greatly weakening the illumination intensity of the external light. At the same time, the adjacent two reflecting members 160 are located on the isolation layer 120 on both sides of the light-emitting layer 130, so that the light irradiated or reflected by the adjacent two light-emitting areas 180 can be blocked, preventing the light from interfering between the adjacent light-emitting areas 180 in the reflection process. This reduces the reflection of external light between the electrode layer 140, the light-emitting layer 130 and the substrate 110, reduces the influence of external light on the display panel 100, and improves the display effect of the display panel 100.

[0028] It should be noted that the light absorbed by the first light-absorbing layer 151 and the second light-absorbing layer 152 is the polarized light corresponding to the light-absorbing axis of the first light-absorbing layer 151 and the second light-absorbing layer 152.

[0029] Specifically, the light-absorbing layer 150 is an anisotropic light-absorbing layer 150, the light-absorbing axis of the first light-absorbing layer 151 is 90°, and the light-absorbing axis of the second light-absorbing layer 152 is 0°. The application uses the first light-absorbing layer 151 to absorb polarized light with a polarization angle of 90° in the propagation process of external light, and the second light-absorbing layer 152 to absorb polarized light with a polarization angle of 0° in the propagation process of external light, thereby reducing the illumination intensity of external light and further reducing the influence of external light on the display panel 100.

[0030] When external light is incident on the display panel 100 from the side of the first light-absorbing layer 151, the first light-absorbing layer 151 will first absorb polarized light with a polarization angle of 90° in the external incident light, achieving the first weakening of the intensity of external light; other angle polarized light will be incident on the reflecting element 160 in the display panel 100 through the first light-absorbing layer 151, the reflecting element 160 will reflect the light to the second light-absorbing layer 152, and the second light-absorbing layer 152 will absorb polarized light with a polarization angle of 0° in the external light incident in the display panel 100, achieving the second weakening of the intensity of external light, and finally a small part of the light will be re-emitted out of the display panel 100; and because the light-absorbing axis angles of the first light-absorbing layer 151 and the second light-absorbing layer 152 are different, the second light-absorbing layer 152 and the first light-absorbing layer 151 absorb light with different polarization angles, respectively, when external light is incident on the display panel 100 from the side of the second light-absorbing layer 152, the second light-absorbing layer 152 will first absorb polarized light with a polarization angle of 0° in the external incident light, achieving the first weakening of the intensity of external light; other direction polarized light will be incident on the reflecting element 160 in the display panel 100 through the second light-absorbing layer 152, the reflecting element 160 will reflect the light to the first light-absorbing layer 151, and the first light-absorbing layer 151 will absorb polarized light with a polarization angle of 90° in the external light incident in the display panel 100, achieving the second weakening of the intensity of external light, and finally a small part of the light will be re-emitted out of the display panel 100; that is, the application uses the first light-absorbing layer 151 or the second light-absorbing layer 152 to first absorb polarized light with a polarization angle of 90° or 0° when external light is first incident, and then uses the reflecting element 160 to adjust the incident path of external light that has passed through the first light-absorbing layer 151 or the second light-absorbing layer 152, so that the first light-absorbing layer 151 or the second light-absorbing layer 152 respectively forms a second absorption of polarized light with a polarization angle of 0° or 90°, thereby greatly weakening the illumination intensity of external light and reducing the influence of external light on the display panel 100, thereby improving the display effect of the display panel 100.

[0031] Further, the reflecting member 160 includes a first reflecting member 161, a second reflecting member 162, and a plurality of third reflecting members 163. The first reflecting member 161 and the second reflecting member 162 are respectively located on two sides of the display panel 100, and the plurality of third reflecting members 163 are arranged at intervals between the first reflecting member 161 and the second reflecting member 162. The first reflecting member 161 and the second reflecting member 162 each include a first bevel 167, which is inclined at a preset angle towards the light-absorbing layer 150. The third reflecting member 163 includes a second bevel 164 and a third bevel 165 arranged oppositely. The second bevel 164 and the third bevel 165 of adjacent two third reflecting members 163 correspond to each other and are each inclined at a preset angle towards one side of the light-absorbing layer 150.

[0032] Since the first reflecting member 161 and the second reflecting member 162 located on two sides of the display panel 100 only need to reflect light in the direction of the inner side of the display panel 100 to change the propagation path of the light, the side of the first reflecting member 161 and the second reflecting member 162 close to the inner side of the display panel 100 is set as a bevel, i.e., the first bevel 167. When the light irradiates towards the edge of the display panel 100, it can irradiate on the first bevel 167. The first bevel 167 of the first reflecting member 161 and the second reflecting member 162 reflects the light to the first light-absorbing layer 151 or the second light-absorbing layer 152, thereby achieving path adjustment of the light and making the first light-absorbing layer 151 and the second light-absorbing layer 152 form secondary absorption of the external ambient light inside the display panel 100, thereby weakening the intensity of the external ambient light and reducing the influence of the external ambient light on the display panel 100.

[0033] Since the third reflecting member 163 located between the first reflecting member 161 and the second reflecting member 162 is irradiated by light on both sides in the horizontal direction of the display panel 100, the second bevel 164 and the third bevel 165 are respectively arranged on both sides of the third reflecting member 163 in the horizontal direction of the display panel 100. The second bevel 164 can be arranged corresponding to the first bevel 167 of the first reflecting member 161, and the third bevel 165 can be arranged corresponding to the first bevel 167 of the second reflecting member 162.

[0034] Taking the light-emitting region 180 formed between the first reflecting piece 161 and the third reflecting piece 163 adjacent thereto as an example: the first light-absorbing layer 151 in the light-emitting region 180 is arranged close to the first reflecting piece 161, and the second light-absorbing layer 152 is arranged close to the third reflecting piece 163; when external light is incident into the display panel 100, part of the light incident onto the first reflecting piece 161 is adjusted in propagation path by the first bevel 167, so that the light is incident onto the second light-absorbing layer 152, and the polarized light with a polarization angle of 0° is absorbed by the second light-absorbing layer 152, thereby reducing the illumination intensity; and part of the light incident onto the third reflecting piece 163 is adjusted in propagation path by the second bevel 164, so that the light is incident onto the first light-absorbing layer 151, and the polarized light with a polarization angle of 90° is absorbed by the first light-absorbing layer 151, thereby reducing the illumination intensity.

[0035] Meanwhile, the light emitted by the light-emitting layer 130 of the light-emitting region 180 and the light reflected by the electrode layer 140 from the external environment light is also adjusted in route by the first bevel 167 of the first reflecting piece 161 and the second bevel 164 of the third reflecting piece 163, so that the polarized light with a specific angle in this part of light is absorbed by the first light-absorbing layer 151 or the second light-absorbing layer 152, thereby reducing the reflection of the light in the display panel 100.

[0036] Furthermore, the third reflecting piece 163 can also block the light from being incident or reflected onto the adjacent light-emitting region 180, preventing the light from forming interference between the adjacent light-emitting regions 180 in the process of reflection, so as to reduce the reflection of the external light between the electrode layer 140, the light-emitting layer 130 and the substrate 110, and reduce the influence of the external light on the display panel 100, thereby improving the display effect of the display panel 100.

[0037] Taking the light-emitting region 180 formed between the second reflecting piece 162 on the other side and the third reflecting piece 163 adjacent thereto as an example: the second light-absorbing layer 152 in the light-emitting region 180 is arranged close to the second reflecting piece 162, and the first light-absorbing layer 151 is arranged close to the third reflecting piece 163; when external light is incident into the display panel 100, part of the light incident onto the second reflecting piece 162 is adjusted in propagation path by the first bevel 167, so that the light is incident onto the first light-absorbing layer 151, and the polarized light with a polarization angle of 90° is absorbed by the first light-absorbing layer 151, thereby reducing the illumination intensity; and part of the light incident onto the third reflecting piece 163 is adjusted in propagation path by the third bevel 165, so that the light is incident onto the second light-absorbing layer 152, and the polarized light with a polarization angle of 0° is absorbed by the second light-absorbing layer 152, thereby reducing the illumination intensity.

[0038] Meanwhile, the light emitted by the light emitting layer 130 of the light emitting area 180 and the light reflected by the electrode layer 140 from the external environment light also passes through the first inclined edge 167 of the second reflective member 162 and the third inclined edge 165 of the third reflective member 163 for route adjustment, so that the light is absorbed by the first light absorbing layer 151 or the second light absorbing layer 152, thereby reducing the reflection of the light in the display panel 100.

[0039] In addition, the third reflective member 163 can also block the light from being irradiated or reflected to the adjacent light emitting area 180, preventing the light from forming interference between the adjacent light emitting areas 180 in the process of reflection, so as to reduce the reflection of the external light between the electrode layer 140, the light emitting layer 130 and the substrate 110, reduce the influence of the external light on the display panel 100, and improve the display effect of the display panel 100.

[0040] Similarly, the two adjacent third reflective members 163 have the same effect on the light emitting area 180 they limit, which will not be repeated here.

[0041] In order to ensure that the first reflective member 161, the second reflective member 162 and the third reflective member 163 can better adjust the light to the direction of the light absorbing layer 150 when receiving the light irradiation, so that the polarized light of the reflected light can be better absorbed by the light absorbing layer 150, therefore, the angle of the inclined edge of the reflected light of the first reflective member 161, the second reflective member 162 and the third reflective member 163 is also designed, which is as follows:

[0042] The angle range of the inclination angle a of the first inclined side 167, the second inclined side 164 and the third inclined side 165 relative to the electrode layer 140 is between 60° and 80°. If the inclination angle between the first inclined side 167, the second inclined side 164 and the third inclined side 165 and the electrode layer 140 is less than 60°, the first inclined side 167, the second inclined side 164 and the third inclined side 165 are not easy to receive the light reflected from the light-emitting layer 130, the electrode layer 140 and the substrate 110, and if the inclination angle between the first inclined side 167, the second inclined side 164 and the third inclined side 165 and the electrode layer 140 is greater than 80°, the first inclined side 167, the second inclined side 164 and the third inclined side 165 tend to be perpendicular, which is not conducive to conducting the reflected light to the light-absorbing layer 150 above. Therefore, the inclination angle range of the first inclined side 167, the second inclined side 164 and the third inclined side 165 relative to the electrode layer 140 is set to be between 60° and 80°, for example, when the inclination angle between the first inclined side 167, the second inclined side 164 and the third inclined side 165 and the electrode layer 140 is 70°, the light can be better adjusted to the light-absorbing layer 150, so that the reflected light can be better absorbed by the light-absorbing layer 150; and the reflected light from the electrode layer 140, the light-emitting layer 130 and the substrate 110 is reduced, which is conducive to improving the display effect of the display panel 100.

[0043] Further, the cross section of the second reflecting member 162 is triangular or trapezoidal. The second reflecting member 162 in the present application can be a triangular structure or a trapezoidal structure. When the second reflecting member 162 is a triangular structure, the inclined side of the triangular structure can be used to reflect light, thereby adjusting the propagation path of the light; and when the second reflecting member 162 is a trapezoidal structure, not only the two inclined sides of the trapezoidal structure can be used to reflect light, but also the upper base and the lower base of the trapezoidal structure can be used to support the light-absorbing layer 150 and the electrode layer 140 respectively, thereby improving the overall structural stability of the display panel 100.

[0044] Specifically, the reflecting member 160 includes a first part 171 and a second part 172. The first part 171 is embedded in the light-absorbing layer 150, and the second part 172 is located between the light-absorbing layer 150 and the electrode layer 140. The first part 171 is made of transparent material, and the outer surface of the second part 172 is provided with a reflecting layer 173.

[0045] In this embodiment, the reflecting member 160 is composed of two parts, the first part 171 is embedded in the light-absorbing layer 150, so that the reflecting member 160 can form a stable connection with the light-absorbing layer 150, so that the reflecting member 160 is not easy to shake or dislocation in the light-absorbing layer 150, so that the reflecting member 160 appears deviation of light adjustment, ensures the stability of the reflecting member 160 to light processing, at the same time, the part embedded in the light-absorbing layer 150 is made of transparent material, so as not to appear shadow and affect the normal display of the display panel 100.

[0046] And the second part 172 is located between the light-absorbing layer 150 and the electrode layer 140, and the outer surface of the second part 172 is provided with a reflecting layer 173, so that the external environment light can be reflected by the second part 172 when it irradiates into the display panel 100, thereby adjusting the propagation path of the external environment light and conducting the external environment light to the light-absorbing layer 150. After the secondary absorption of the light-absorbing layer 150, the light intensity is weakened, and then the influence of the external environment light on the display panel 100 is reduced.

[0047] Further, the distance between the light-absorbing layer 150 and the electrode layer 140 is 1.5 to 3 times the thickness of the light-absorbing layer 150. This design can make the external environment light irradiate into the display panel 100, and the light can be transmitted and path adjusted by the reflecting member 160, increase the number of light reflection, so that the external environment light can be more easily adjusted by the reflecting member 160. After irradiation to the light-absorbing layer 150, the secondary absorption of the light-absorbing layer 150 is realized, so as to effectively weaken the light intensity and reduce the influence of the environment light on the display panel 100, and improve the display effect of the display panel 100.

[0048] Figure 2 The second embodiment of the display panel of the present application is shown in the schematic view as shown in Figure 2 The reflecting member 160 is located between the light-absorbing layer 150 and the electrode layer 140, and the reflecting member 160 is in abutment with the light-absorbing layer 150 and the electrode layer 140, respectively.

[0049] The difference between this embodiment and the previous embodiment is that in this embodiment, the reflecting member 160 is located between the light-absorbing layer 150 and the electrode layer 140, and the two sides of the reflecting member 160 are in abutment with the light-absorbing layer 150 and the electrode layer 140, respectively. On the one hand, the reflecting member 160 is used to reflect the light in the display panel 100, and on the other hand, the reflecting member 160 is used to realize the effect of the spacer column between the light-absorbing layer 150 and the electrode layer 140, supporting the light-absorbing layer 150 and the electrode layer 140, thereby ensuring the structural stability of the display panel 100.

[0050] Further, the outer surface of the reflecting member 160 is provided with a reflecting layer 173, and the inner part of the reflecting member 160 is made of light shielding material. In this way, on the one hand, the reflecting member 160 can adjust the irradiation path of the external environmental light irradiated into the display panel 100, so that the light can be absorbed by the light absorbing layer 150, thereby greatly weakening the illumination intensity of the external light; at the same time, the light irradiated or reflected by the adjacent two light emitting areas 180 can be blocked by the reflecting member 160, preventing the light from forming interference between the adjacent light emitting areas 180 in the process of reflection, thereby reducing the reflection of external light between the electrode layer 140, the light emitting layer 130 and the substrate 110, reducing the influence of external light on the display panel 100, and improving the display effect of the display panel 100.

[0051] Figure 3 FIG. 1 shows a schematic diagram of an embodiment of a display device of the present application, and Figure 3 As shown in FIG. 1, the embodiment of the present application also discloses a display device 10, which comprises a back plate 200, and the display device 10 further comprises the display panel 100 described above, and the back plate 200 wraps the display panel 100. The back plate 200 is used to protect the display panel 100 from being damaged by external forces during movement or transportation, and to a certain extent, it can also improve the problem of water vapor intrusion in the external environment, thereby prolonging the service life of the display panel 100.

[0052] In the process of using the display device 10, external light irradiates the display panel 100 and will be refracted and reflected on the internal components of the display panel 100. The reflected light reflected from the internal components of the display panel 100 will have a negative impact on the display effect of the display panel 100 after being superimposed with the display light of the display panel 100.

[0053] Based on the above problems, the display panel 100 in the display device 10 is improved, and the light-absorbing layer 150 and the reflecting member 160 are arranged in the display panel 100. When the external light is irradiated to the display panel 100 from the side of the first light-absorbing layer 151, the first light-absorbing layer 151 first absorbs part of the external light, the external light that passes through the first light-absorbing layer 151 is irradiated to the reflecting member 160 in the display panel 100, the reflecting member 160 reflects the light to the second light-absorbing layer 152, the second light-absorbing layer 152 absorbs part of the light irradiated into the display panel 100 again, and finally a small part of the light is emitted out of the display panel 100. Because the light-absorbing axes of the first light-absorbing layer 151 and the second light-absorbing layer 152 are different, the second light-absorbing layer 152 and the first light-absorbing layer 151 absorb polarized light with different polarization angles, respectively. When the external light is irradiated to the display panel 100 from the side of the second light-absorbing layer 152, the second light-absorbing layer 152 first absorbs part of the external light, the external light that passes through the second light-absorbing layer 152 is irradiated to the reflecting member 160 in the display panel 100, then the reflecting member 160 reflects the light to the first light-absorbing layer 151, the first light-absorbing layer 151 absorbs part of the light irradiated into the display panel 100 again, and finally a small part of the light is emitted out of the display panel 100. That is, the first light-absorbing layer 151 or the second light-absorbing layer 152 absorbs the external light for the first time when the external light is irradiated, the reflecting member 160 adjusts the irradiation path of the external light that passes through the first light-absorbing layer 151 or the second light-absorbing layer 152, so that the first light-absorbing layer 151 or the second light-absorbing layer 152 forms the second absorption of the external light, thereby greatly weakening the illumination intensity of the external light. Meanwhile, the adjacent two reflecting members 160 are located on the isolation layer 120 on both sides of the light-emitting layer 130, so that the light irradiated or reflected by the adjacent two light-emitting areas 180 can be blocked, preventing the light from interfering between the adjacent light-emitting areas 180 in the reflection process. In this way, the reflection of the external light between the electrode layer 140, the light-emitting layer 130 and the substrate 110 is reduced, the influence of the external light on the display panel 100 is reduced, the display effect of the display panel 100 is improved, and the quality of the display device 10 is improved.
