[0022] The present application is described in detail below with reference to the accompanying drawings and optional embodiments.

[0023] Figure 1is a schematic diagram of a first embodiment of a display panel of the present application, such as Figure 1 As shown, the embodiment of the present application discloses a display panel 100, including a base substrate 110, on which an isolation layer 120 is arranged at intervals, a light-emitting layer 130 is arranged between two adjacent isolation layers 120, and an electrode layer 140 is arranged on the light-emitting layer 130 and the isolation layer 120; the display panel 100 also includes a light-absorbing layer 150, the light-absorbing layer 150 is arranged opposite to the electrode layer 140, and a plurality of reflective members 160 are arranged between the light-absorbing layer 150 and the electrode layer 140; each reflective member 160 corresponds to the isolation layer 1 20; a light-emitting area 180 is formed between two adjacent reflective members 160; the light-absorbing layer 150 includes a first light-absorbing layer 151 and a second light-absorbing layer 152, and the first light-absorbing layer 151 and the second light-absorbing layer 152 are arranged corresponding to the light-emitting area 180; the light-absorbing axes of the first light-absorbing layer 151 and the second light-absorbing layer 152 are different; the reflective member 160 is used to reflect the external light passing through the first light-absorbing layer 151 to the second light-absorbing layer 152, or to reflect the external light passing through the second light-absorbing layer 152 to the first light-absorbing layer 151.

[0024] In the present application, a reflective member 160 and a light absorbing layer 150 with different light absorbing axes are arranged in the display panel 100. When external light is irradiated to the display panel 100 from the first light absorbing layer 151, the first light absorbing layer 151 will first absorb a portion of the external light, and the external light passing through the first light absorbing layer 151 will irradiate the reflective member 160 in the display panel 100. The reflective member 160 reflects the light to the second light absorbing layer 152, and the second light absorbing layer 152 will absorb a portion of the light irradiated into the interior of the display panel 100 again. , and finally a small part of the light is re-emitted out of the display panel 100; and because the light absorption axes of the first light absorption layer 151 and the second light absorption layer 152 are different, the second light absorption layer 152 and the first light absorption layer 151 absorb light with different polarization angles respectively. When external light irradiates the display panel 100 from the second light absorption layer 152, the second light absorption layer 152 will first absorb a part of the external light, and the external light passing through the second light absorption layer 152 will irradiate the reflective element 160 in the display panel 100, and then the light is reflected by the reflective element 160. The first light absorbing layer 151 is used to absorb part of the light irradiated into the display panel 100, and finally a small part of the light is re-emitted out of the display panel 100; that is, the first light absorbing layer 151 or the second light absorbing layer 152 is used to absorb the external light for the first time when it is irradiated at the beginning, and then the reflector 160 is used to adjust the irradiation path of the external light passing 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 a second absorption of the external light. At the same time, two adjacent reflectors 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 two adjacent light-emitting areas 180 can be blocked to prevent the light from interfering with the adjacent light-emitting areas 180 during the reflection process, thereby reducing the reflection effect of the electrode layer 140, the light-emitting layer 130 and the base substrate 110 on the external light, reducing the influence of the external light on the illumination of the display panel 100, thereby improving the display effect of the display panel 100.

[0025] It should be noted that the light absorbed by the first light absorption layer 151 and the second light absorption layer 152 are polarized lights corresponding to the light absorption axes of the first light absorption layer 151 and the second light absorption layer 152 .

[0026] 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 present application utilizes the first light absorbing layer 151 to absorb polarized light with a polarization angle of 90° during the propagation of external light, and the second light absorbing layer 152 to absorb polarized light with a polarization angle of 0° during the propagation of external light, thereby reducing the light intensity of the external light, and further reducing the influence of the external light on the display panel 100.

[0027] When external light irradiates the display panel 100 from one side of the first light absorbing layer 151, the first light absorbing layer 151 will first absorb the polarized light with a polarization angle of 90° in the external irradiated light, thereby achieving the first weakening of the intensity of the external light; while polarized light with other angles will pass through the first light absorbing layer 151 and irradiate the reflector 160 in the display panel 100, and the reflector 160 will reflect the light to the second light absorbing layer 152, and the second light absorbing layer 152 will absorb the polarized light with a polarization angle of 0° in the external light irradiated into the display panel 100. ° polarized light is absorbed to achieve a second weakening of the intensity of the external light, and finally a small part of the light is re-emitted out of the display panel 100; and because the light absorption axis angles of the first light absorption layer 151 and the second light absorption layer 152 are different, the second light absorption layer 152 and the first light absorption 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 absorption layer 152, the second light absorption layer 152 will first absorb the polarized light with a polarization angle of 0 ° in the external irradiation light, achieving the first external The intensity of the external light is weakened; while the polarized light in other directions passes through the second light absorbing layer 152 and irradiates the reflective member 160 in the display panel 100, and the reflective member 160 reflects the light to the first light absorbing layer 151, and the first light absorbing layer 151 absorbs the polarized light with a polarization angle of 90° in the external light irradiating into the interior of the display panel 100, thereby achieving a second weakening of the intensity of the external light, and finally re-emitting a small part of the light out of the display panel 100; that is, the present application uses the first light absorbing layer 151 or the second light absorbing layer 152 to When external light is first irradiated, polarized light with a polarization angle of 90° or 0° is absorbed for the first time, and then the reflector 160 is used to adjust the irradiation path of the external light passing 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 again absorbs the polarized light with a polarization angle of 0° or 90° for the second time, thereby greatly weakening the light intensity of the external light, reducing the influence of the external light on the irradiation of the display panel 100, and thus improving the display effect of the display panel 100.

[0028] Furthermore, the reflector 160 includes a first reflector 161, a second reflector 162 and a plurality of third reflectors 163, the first reflector 161 and the second reflector 162 are respectively located on both sides of the display panel 100, and the plurality of third reflectors 163 are spaced apart between the first reflector 161 and the second reflector 162; the first reflector 161 and the second reflector 162 both include a first hypotenuse 167, and the first hypotenuse 167 is inclined at a preset angle toward the light absorbing layer 150; the third reflector 163 includes a second hypotenuse 164 and a third hypotenuse 165 which are arranged opposite to each other, the second hypotenuse 164 of two adjacent third reflectors 163 corresponds to the third hypotenuse 165, and both are inclined at a preset angle toward one side of the light absorbing layer 150.

[0029] Since the first reflector 161 and the second reflector 162 located on both sides of the display panel 100 only need to reflect the light toward the inner side of the display panel 100 to change the propagation path of the light, the side of the first reflector 161 and the second reflector 162 close to the inner side of the display panel 100 is set as a bevel, that is, the first bevel 167, so that when the light is irradiated to the edge of the display panel 100, it can be irradiated on the first bevel 167, and the first bevel 167 of the first reflector 161 and the second reflector 162 is used to reflect the light to the first light absorption layer 151 or the second light absorption layer 152, so as to achieve the path adjustment of the light, and at the same time, the first light absorption layer 151 and the second light absorption 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.

[0030] Since the third reflector 163 located between the first reflector 161 and the second reflector 162 is exposed to light on both sides of the display panel 100 in the horizontal direction, the third reflector 163 is respectively provided with a second bevel 164 and a third bevel 165 on both sides of the display panel 100 in the horizontal direction. The second bevel 164 can be provided corresponding to the first bevel 167 of the first reflector 161, and the third bevel 165 can be provided corresponding to the first bevel 167 of the second reflector 162.

[0031] Take the light-emitting area 180 formed between the first reflector 161 and the third reflector 163 adjacent thereto as an example: the first light absorption layer 151 in the light-emitting area 180 is arranged close to the first reflector 161, and the second light absorption layer 152 is arranged close to the third reflector 163; when external light irradiates the interior of the display panel 100, a part of the light irradiated to the first reflector 161 will adjust the propagation path of the light through the first bevel 167, so that the light irradiates toward the second light absorption layer 152, and the polarized light with a polarization angle of 0° is absorbed by the second light absorption layer 152, thereby reducing the light intensity; and a part of the light irradiated to the third reflector 163 will adjust the propagation path of the irradiated light through the second bevel 164, so that the light irradiates toward the first light absorption layer 151, and the polarized light with a polarization angle of 90° is absorbed by the first light absorption layer 151, thereby reducing the light intensity.

[0032] At the same time, the light emitted by the light-emitting layer 130 of the light-emitting area 180 and the light reflected by the external ambient light on the electrode layer 140 will also be adjusted through the first bevel 167 of the first reflector 161 and the second bevel 164 of the third reflector 163, so that the polarized light of a specific angle in this part of the light is absorbed by the first light absorption layer 151 or the second light absorption layer 152, thereby reducing the reflection of light in the display panel 100.

[0033] In addition, the third reflector 163 can also block the light from irradiating or reflecting toward the adjacent light-emitting area 180, and prevent the light from interfering with the adjacent light-emitting areas 180 during the reflection process. This reduces the reflection effect of external light between the electrode layer 140, the light-emitting layer 130 and the base substrate 110, and reduces the influence of external light on the display panel 100, thereby improving the display effect of the display panel 100.

[0034] Take the light-emitting area 180 formed between the second reflector 162 on the other side and the third reflector 163 adjacent thereto as an example: the second light-absorbing layer 152 in the light-emitting area 180 is arranged close to the second reflector 162, and the first light-absorbing layer 151 is arranged close to the third reflector 163; when external light irradiates the interior of the display panel 100, a part of the light irradiated to the second reflector 162 will adjust the propagation path of the light through the first bevel 167, so that the light irradiates toward 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 light intensity; and a part of the light irradiated to the third reflector 163 will adjust the propagation path of the irradiated light through the third bevel 165, so that the light irradiates toward 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 light intensity.

[0035] At the same time, the light emitted by the light-emitting layer 130 of the light-emitting area 180 and the light reflected by the external ambient light on the electrode layer 140 will also be adjusted through the first bevel 167 of the second reflector 162 and the third bevel 165 of the third reflector 163, so that this part of the light is absorbed by the first light absorption layer 151 or the second light absorption layer 152, thereby reducing the reflection of light in the display panel 100.

[0036] In addition, the third reflector 163 can also block the light from irradiating or reflecting toward the adjacent light-emitting area 180, and prevent the light from interfering with the adjacent light-emitting areas 180 during the reflection process. This reduces the reflection effect of external light between the electrode layer 140, the light-emitting layer 130 and the base substrate 110, and reduces the influence of external light on the display panel 100, thereby improving the display effect of the display panel 100.

[0037] Similarly, two adjacent third reflectors 163 also have the same effect on the light emitting area 180 restricted by them, which will not be described in detail.

[0038] In order to ensure that the first reflector 161, the second reflector 162 and the third reflector 163 can better adjust the light to the direction of the light absorbing layer 150 when receiving the light, so that the polarized light of the reflected light can be better absorbed by the light absorbing layer 150, the present application also designs the angle of the hypotenuse inclination angle α of the reflected light of the first reflector 161, the second reflector 162 and the third reflector 163, as follows: The angle range of the inclination angle α of the first oblique edge 167, the second oblique edge 164 and the third oblique edge 165 relative to the electrode layer 140 is between 60° and 80°. If the inclination angle between the first oblique edge 167, the second oblique edge 164 and the third oblique edge 165 and the electrode layer 140 is less than 60°, the first oblique edge 167, the second oblique edge 164 and the third oblique edge 165 are not easy to receive the light reflected from the light emitting layer 130, the electrode layer 140 and the base substrate 110, and if the inclination angle between the first oblique edge 167, the second oblique edge 164 and the third oblique edge 165 and the electrode layer 140 is greater than 80°, the first oblique edge 167, the second oblique edge 164 and the third oblique edge 165 tend to be vertical, which is not conducive to transmitting the reflected light to the light absorbing layer 110 above. 50, therefore, the inclination angle range of the first oblique edge 167, the second oblique edge 164 and the third oblique edge 165 relative to the electrode layer 140 is set between 60° and 80°. For example, when the inclination angle between the first oblique edge 167, the second oblique edge 164 and the third oblique edge 165 and the electrode layer 140 is 70°, the light can be better adjusted to the direction of 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 base substrate 110 is reduced, which is beneficial to improving the display effect of the display panel 100.

[0039] Furthermore, the cross section of the second reflector 162 is a triangle or a trapezoid. The second reflector 162 in the present application can be a triangular structure or a trapezoidal structure. When the second reflector 162 is a triangular structure, the hypotenuse of the triangular structure can be used to reflect the light, thereby adjusting the propagation path of the light; and when the second reflector 162 is a trapezoidal structure, not only can the two hypotenuses of the trapezoidal structure be used to reflect the light, but also the upper and lower bases 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.

[0040] Specifically, the reflector 160 includes a first portion 171 and a second portion 172 . The first portion 171 is embedded in the light absorbing layer 150 , and the second portion 172 is located between the light absorbing layer 150 and the electrode layer 140 . The first portion 171 is made of a transparent material, and a reflective layer 173 is disposed on the outer surface of the second portion 172 .

[0041] In this embodiment, the reflective element 160 is composed of two parts. The first part 171 is embedded in the light absorbing layer 150, so that the reflective element 160 can form a stable connection with the light absorbing layer 150, making it difficult for the reflective element 160 to shake or misalign in the light absorbing layer 150, causing the reflective element 160 to deviate from the light adjustment, thereby ensuring the stability of the reflective element 160 in processing light. At the same time, the part embedded in the light absorbing layer 150 is made of transparent material, so that no shadow will appear to affect the normal display of the display panel 100.

[0042] The second part 172 is located between the light absorbing layer 150 and the electrode layer 140, and a reflective layer 173 is provided on the outer surface of the second part 172, so that when the external ambient light is irradiated into the display panel 100, it can be reflected by the second part 172, thereby adjusting the propagation path of the external ambient light and transmitting the external ambient light to the light absorbing layer 150. After secondary absorption by the light absorbing layer 150, the light intensity is weakened, thereby reducing the influence of the external ambient light on the display panel 100.

[0043] Furthermore, the spacing between the light absorbing layer 150 and the electrode layer 140 is between 1.5 and 3 times the thickness of the light absorbing layer 150. This design allows the external ambient light to be better transmitted and adjusted in path through the reflector 160 when irradiating into the display panel 100, increasing the number of light reflections, so that the external ambient light can be more easily adjusted by the reflector 160 and then re-irradiated to the light absorbing layer 150, achieving secondary absorption by the light absorbing layer 150, thereby effectively weakening the light intensity, reducing the impact of ambient light on the display panel 100, and improving the display effect of the display panel 100.

[0044] Figure 2 is a schematic diagram of a second embodiment of a display panel of the present application, such as Figure 2 As shown, the reflective member 160 is located between the light absorbing layer 150 and the electrode layer 140 , and the reflective member 160 abuts against the light absorbing layer 150 and the electrode layer 140 respectively.

[0045] This embodiment is different from the previous embodiment in that, in this embodiment, the reflective member 160 is located between the light absorbing layer 150 and the electrode layer 140, and the two sides of the reflective member 160 are respectively in contact with the light absorbing layer 150 and the electrode layer 140. On the one hand, the reflective member 160 is used to reflect the light inside the display panel 100, and on the other hand, the reflective member 160 is used to achieve an effect similar to a spacer column between the light absorbing layer 150 and the electrode layer 140, so as to support the light absorbing layer 150 and the electrode layer 140, thereby ensuring the structural stability of the display panel 100.

[0046] Furthermore, a reflective layer 173 is provided on the outer surface of the reflector 160, and the interior of the reflector 160 is made of a light-shielding material. In this way, on the one hand, the reflector 160 can adjust the irradiation path of the external ambient 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 reflector 160 can be used to block the light irradiated or reflected by two adjacent light-emitting areas 180, to prevent the light from interfering with the adjacent light-emitting areas 180 during the reflection process, thereby reducing the reflection effect of the electrode layer 140, the light-emitting layer 130 and the base substrate 110 on the external light, reducing the influence of the external light on the irradiation of the display panel 100, thereby improving the display effect of the display panel 100.

[0047] Figure 3 is a schematic diagram of an embodiment of a display device of the present application, such as Figure 3 As shown, the embodiment of the present application further discloses a display device 10, including a back plate 200, and the display device 10 also includes the above-mentioned display panel 100, and the back plate 200 wraps the display panel 100. The back plate 200 is used to protect the display panel 100 from being easily damaged by external forces during movement or transportation, and can improve the problem of water vapor intrusion in the external environment to a certain extent, thereby extending the service life of the display panel 100.

[0048] When the display device 10 is in use, external light is directed toward the display panel 100 and is refracted and reflected on the internal components of the display panel 100 . The reflected light from the internal components of the display panel 100 and the display light of the display panel 100 are superimposed on each other, which will have a negative impact on the display effect of the display panel 100 .

[0049] Based on the above problems, the present application improves the display panel 100 in the display device 10. The present application sets a light absorbing layer 150 and a reflective member 160 in the display panel 100. When external light irradiates the display panel 100 from the first light absorbing layer 151, the first light absorbing layer 151 will first absorb a part of the external light, and the external light passing through the first light absorbing layer 151 will irradiate the reflective member 160 in the display panel 100. The reflective member 160 reflects the light to the second light absorbing layer 152. The second light absorbing layer 152 is used to absorb the light irradiated into the display panel 100. 00, and finally re-emits a small part of the light outside the display panel 100; and because the light absorption axes of the first light absorption layer 151 and the second light absorption layer 152 are different, the second light absorption layer 152 and the first light absorption layer 151 absorb polarized light with different polarization angles respectively. When external light irradiates the display panel 100 from the second light absorption layer 152, the second light absorption layer 152 will first absorb a part of the external light, and the external light passing through the second light absorption layer 152 will irradiate the reflective element 160 in the display panel 100, and then pass through the reflective element 160. The first light absorbing layer 151 is used to reflect the light to the first light absorbing layer 151, and the first light absorbing layer 151 is used to absorb part of the light irradiated into the display panel 100 again, and finally a small part of the light is re-emitted out of the display panel 100; that is, the present 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 it is irradiated at the beginning, and then uses the reflector 160 to adjust the irradiation path of the external light passing 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 a second absorption of the external light, thereby greatly The light intensity of external light is greatly weakened; at the same time, two adjacent reflectors 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 two adjacent light-emitting areas 180 can be blocked to prevent the light from interfering with the adjacent light-emitting areas 180 during the reflection process, thereby reducing the reflection effect of the electrode layer 140, the light-emitting layer 130 and the base substrate 110 on the external light, and reducing the influence of the external light on the display panel 100, thereby improving the display effect of the display panel 100, and further improving the quality of the display device 10.
