Both the light-dense element 337 and the first light-dense element 338 are light-transmissive, and the refractive index of the light-dense element 337 is greater than the refractive index of the first light-dense element 338.

[0054] See also Figure 4 , Figure 4 The solid line with a line arrow in the figure is the path of ambient light entering the display panel 30 from the outside. The ambient light from the outside sequentially passes through the encapsulation layer 34 and the cathode layer 334 to the optically dense element 337. Part of the ambient light is directly emitted to the first optically sparse element 338 through the optically dense element 337, and part of the ambient light is directly emitted to the reflective element 336 through the optically dense element 337. The surface where the first optically sparse element 338 and the optically dense element 337 are connected totally reflects the ambient light directly emitted to the first optically sparse element 338 to the reflective element 336. Figure 4The dotted line with a line arrow in the figure is the path of the ambient light emitted from the display panel 30 to the outside. The reflective element 336 reflects the ambient light directly emitted to the reflective element 336 and the ambient light totally reflected to the reflective element 336 to the side of the optically dense element 337 facing away from the reflective element 336 and the first optically sparse element 338. The surface of the first optically sparse element 338 connected to the optically dense element 337 totally reflects the ambient light reflected to the first optically sparse element 338 to the side of the optically dense element 337 facing away from the reflective element 336. The ambient light sequentially transmits through the cathode layer 334 and the encapsulation layer 34 to the light-emitting side of the display panel 30, so that the brightening area A21 emits light. Among them, the light-emitting side of the display panel 30 is the side of the encapsulation layer 34 facing away from the cathode layer 334.

[0055] It can be understood that the brightening area A21 is at least part of the peripheral area of ​​the sub-pixel area A1. In the prior art, the peripheral area of ​​the sub-pixel area A1 is non-luminous. Therefore, the technical solution of the present application enables the brightening area A21 to emit light, that is, at least part of the peripheral area of ​​the sub-pixel area A1 emits light, which increases the effective aperture ratio of the display panel 30, that is, increases the ratio of the area of ​​the light-emitting surface of the display panel 30 to the area of ​​the light-emitting side of the display panel 30. At the same time, the light emission of the brightening area A21 also increases the display brightness of the display panel 30, thereby improving the display effect of the display panel 30. Moreover, the brightening area A21 uses ambient light to emit light. The brightening area A21 increases the display brightness of the display panel 30 without increasing the power consumption of the display panel 30, which is beneficial to reducing the use cost of the display panel 30.

[0056] It should be noted that the surface where the first optically sparse element 338 is connected to the optically dense element 337 can totally reflect the ambient light to the reflective element 336 through at least one total reflection, or can totally reflect the ambient light to the side of the optically dense element 337 facing away from the reflective element 336 through at least one total reflection.

[0057] In an exemplary embodiment, the surfaces where the optically dense element 337 and the first optically sparse element 338 are connected are aligned with the normal viewing direction of the display panel 30 .

[0058] In the implementation mode of this application, please refer to Figure 4The light emitting assembly 33 may further include a plurality of second light-sparse elements 339, one of the second light-sparse elements 339 is disposed in one of the accommodation spaces 331b, the second light-sparse elements 339 are disposed on the side of the light-dense element 337 facing away from the reflective element 336 and the side of the first light-sparse element 338 facing away from the reflective element 336, and part of the cathode layer 334 is disposed on the side of the second light-sparse element 339 facing away from the light-dense element 337 and the side of the second light-sparse element 339 facing away from the first light-sparse element 338, and is connected to the second light-sparse element 339. In other words, the second light-sparse element 339 is connected to the side of the first light-sparse element 338 facing away from the reflective element 336, and forms an accommodation cavity with the first light-sparse element 338 that is generally in the shape of an inverted "concave" as a whole, and the light-dense element 337 is located on the reflective element 336 and is accommodated in the accommodation cavity. The ambient light directed toward the side of the optically dense element 337 facing away from the reflective element 336 is transmitted through the second optically sparse element 339 to the cathode layer 334. The refractive index of the cathode layer 334 is greater than the refractive index of the second optically sparse element 339, and the surface of the cathode layer 334 connected to the second optically sparse element 339 refracts the ambient light directed toward the cathode layer 334 to the encapsulation layer 34, that is, the surface of the cathode layer 334 connected to the second optically sparse element 339 refracts the ambient light directed toward the cathode layer 334 to the side of the cathode layer 334 facing away from the second optically sparse element 339, so as to reduce the angle between the propagation direction of the ambient light and the normal viewing angle direction of the display panel 30.

[0059] It can be understood that, compared with the ambient light in the second light-sparse element 339, the angle between the propagation direction of the ambient light refracted from the surface of the cathode layer 334 connected to the second light-sparse element 339 to the encapsulation layer 34 and the normal viewing direction of the display panel 30 is smaller, thereby improving the luminous brightness at the normal viewing angle or in a direction close to the normal viewing angle of the display panel 30. Users generally watch the display panel 30 from a normal viewing angle or in a direction close to the normal viewing angle, which can improve the luminous brightness at the normal viewing angle or in a direction close to the normal viewing angle of the display panel 30, and is conducive to improving the display effect of the display panel 30.

[0060] In an exemplary embodiment, the first light-dense element 338 and the second light-dense element 339 may be integrally formed, and the first light-dense element 338 and the second light-dense element 339 may have the same refractive index. The refractive index of the cathode layer 334 is greater than the refractive index of the optically dense element 337 .

[0061] In other embodiments, the light emitting component 33 may not include the second light-sparse element 339, and the cathode layer 334 is directly connected to the first light-sparse element 338 and the light-dense element 337. The refractive index of the cathode layer 334 is greater than the refractive index of the light-dense element 337, and the surface of the cathode layer 334 connected to the light-dense element 337 refracts the ambient light directed to the side of the light-dense element 337 facing away from the reflective element 336 to the encapsulation layer 34, so as to reduce the angle between the propagation direction of the ambient light and the normal viewing direction of the display panel 30.

[0062] In an exemplary embodiment, see Figure 4 , the height of the surface where the cathode layer 334 is connected to the second light-sparse element 339 remains unchanged. That is, the surface where the cathode layer 334 is connected to the second light-sparse element 339 is a flat surface, and the normal line of the surface where the cathode layer 334 is connected to the second light-sparse element 339 is parallel to the normal viewing direction of the display panel 30.

[0063] In the embodiment of the present application, the encapsulation layer 34 is disposed on the side of the cathode layer 334 facing away from the pixel defining layer 331, and is connected to the cathode layer 334. The refractive index of the encapsulation layer 34 is greater than the refractive index of the cathode layer 334. The surface of the encapsulation layer 34 connected to the cathode layer 334 in the brightening area A21 refracts the ambient light incident on the encapsulation layer 34 to the light-emitting side of the display panel 30, and the angle between the propagation direction of the ambient light refracted to the light-emitting side of the display panel 30 and the normal viewing angle direction of the display panel 30 is less than a preset angle, so as to improve the luminous brightness of the display panel 30 at the normal viewing angle or a direction close to the normal viewing angle. The light-emitting side of the display panel 30 is the side of the encapsulation layer 34 facing away from the light-emitting component 33.

[0064] In an exemplary embodiment, the preset angle may be 15 degrees to 50 degrees, for example, 15 degrees, 20 degrees, 28 degrees, 35 degrees, 40 degrees, 45 degrees, 50 degrees, or other values, and the present application does not impose any specific limitation on this.

[0065] It should be noted that when ambient light enters the display panel 30 from the outside, the surface of the encapsulation layer 34 connected to the cathode layer 334 will also refract the ambient light, and the surface of the cathode layer 334 connected to the second light-sparse element 339 will also refract the ambient light.

[0066] In an exemplary embodiment, see Figure 4, the surface of the second light-sparse element 339 facing away from the light-dense element 337 is flush with the surface of the pixel-defining layer 331 facing away from the driving circuit layer 32. The height of the light-emitting element 333 is lower than the height of the pixel-defining layer 331, so that the part of the cathode layer 334 located in the sub-pixel area A1 is located in the pixel hole 331a, and then the part of the encapsulation layer 34 is also located in the pixel hole 331a. The height is based on the surface of the substrate 31 facing the driving circuit layer 32 as the reference plane, and the direction from the substrate 31 to the encapsulation layer 34 is the direction of increasing height.

[0067] In an exemplary embodiment, see Figure 4 The ratio of the thickness of the portion of the encapsulation layer 34 extending into the pixel hole 331a to the maximum thickness of the encapsulation layer 34 is 0.3 to 0.6, for example, 0.3, 0.34, 0.38, 0.4, 0.45, 0.5, 0.53, 0.6, or other values, which is not specifically limited in the present application.

[0068] In the implementation mode of this application, please refer to Figure 3 The plurality of light-emitting elements 333 include a plurality of first light-emitting elements 333a, a plurality of second light-emitting elements 333b, and a plurality of third light-emitting elements 333c. Each of the sub-pixel regions A1 is provided with one of the first light-emitting elements 333a, one of the second light-emitting elements 333b, or one of the third light-emitting elements 333c, and three adjacent sub-pixel regions A1 are provided with one of the first light-emitting elements 333a, one of the second light-emitting elements 333b, and one of the third light-emitting elements 333c, respectively. The first light-emitting element 333a is used to emit a first display light, the second light-emitting element 333b is used to emit a second display light, and the third light-emitting element 333c is used to emit a third display light. The first display light may be red light, the second display light may be green light, and the third display light may be blue light.

[0069] In an exemplary embodiment, see Figure 3, the plurality of the first light-emitting elements 333a, the plurality of the second light-emitting elements 333b and the plurality of the third light-emitting elements 333c arranged in the same row (along the first direction 001) can be arranged in the order of: the first light-emitting element 333a, the second light-emitting element 333b, the third light-emitting element 333c, the first light-emitting element 333a, the second light-emitting element 333b, the third light-emitting element 333c, ..., the first light-emitting element 333a, the second light-emitting element 333b, the third light-emitting element 333c. The plurality of the light-emitting elements in the same column are light-emitting elements of the same type, that is, the plurality of the light-emitting elements arranged in the same column (along the second direction 002) are all the plurality of the first light-emitting elements 333a, the plurality of the second light-emitting elements 333b or the plurality of the third light-emitting elements 333c.

[0070] In an exemplary embodiment, the light emitting element 333 may be an organic light emitting diode (OLED) or a micro light emitting diode (Micro LED), which is not specifically limited in the present application.

[0071] See also Figure 5 , Figure 5 This is a schematic diagram of a second partial layer structure of a display panel disclosed in the second embodiment of the present application. Figure 5 The display panel shown is Figure 4 The difference between the display panels shown is that the shapes of the surfaces where the cathode layer 334 and the second light-sparse element 339 are connected are different. Specifically, in the direction from the middle part of the second light-sparse element 339 to the peripheral part of the second light-sparse element 339, the height of the surface where the cathode layer 334 and the second light-sparse element 339 are connected gradually increases, and the height increase rate of the surface where the cathode layer 334 and the second light-sparse element 339 are connected remains unchanged. Among them, the height is based on the surface of the substrate 31 facing the driving circuit layer 32 as the reference plane, and the direction where the substrate 31 points to the encapsulation layer 34 is the direction of height increase. That is, in the direction where the substrate 31 points to the encapsulation layer 34, the surface where the cathode layer 334 and the second light-sparse element 339 are connected is a smooth inclined surface, and its cross section is generally "V"-shaped as a whole, and the height of the connected surface gradually increases from the middle to its peripheral side.

[0072] It can be understood that, in the direction from the middle part of the second light sparse element 339 to the peripheral part of the second light sparse element 339, the height of the surface where the cathode layer 334 is connected to the second light sparse element 339 gradually increases, so that the surface where the cathode layer 334 is connected to the second light sparse element 339 has a certain tilt angle, and the normal direction of the surface where the cathode layer 334 is connected to the second light sparse element 339 changes, thereby adjusting the direction of the ambient light refracted to the encapsulation layer 34 by the surface where the cathode layer 334 is connected to the second light sparse element 339, and further adjusting the range of the angle between the propagation direction of the ambient light refracted to the light emitting side of the display panel 30 and the normal viewing direction of the display panel 30. The smaller the normal direction of the surface where the cathode layer 334 is connected to the second light sparse element 339 and the normal viewing direction of the display panel 30 are, the smaller the range of the angle between the propagation direction of the ambient light refracted to the light emitting side of the display panel 30 and the normal viewing direction of the display panel 30 are.

That is, in the direction from the substrate 31 to the encapsulation layer 34, the surface where the cathode layer 334 and the second light-sparse element 339 are connected is a smooth inclined surface, and its cross section is generally in an inverted "V" shape, and the height of the connected surface gradually decreases from the middle to the peripheral side.

[0074] It can be understood that, in the direction from the middle part of the second light-sparse element 339 to the peripheral part of the second light-sparse element 339, the height of the surface where the cathode layer 334 is connected to the second light-sparse element 339 is gradually reduced, so that the surface where the cathode layer 334 is connected to the second light-sparse element 339 has a certain tilt angle, and the normal direction of the surface where the cathode layer 334 is connected to the second light-sparse element 339 is changed, and the direction of the ambient light refracted to the encapsulation layer 34 by the surface where the cathode layer 334 is connected to the second light-sparse element 339 is adjusted, thereby adjusting the range of the angle between the propagation direction of the ambient light refracted to the light-emitting side of the display panel 30 and the normal viewing direction of the display panel 30. The smaller the normal direction of the surface where the cathode layer 334 is connected to the second light-sparse element 339 and the normal viewing direction of the display panel 30 are, the smaller the range of the angle between the propagation direction of the ambient light refracted to the light-emitting side of the display panel 30 and the normal viewing direction of the display panel 30 are.

For the description of the similarities between the display panel of the third embodiment and the display panel of the second embodiment, please refer to the relevant description of the display panel of the second embodiment, which will not be repeated here.

[0082] In the embodiment of the present application, a plurality of the first color resist elements 37, a plurality of the second color resist elements 38, and a plurality of the third color resist elements 39 are all disposed on the side of the encapsulation layer 34 facing away from the cathode layer 334. Any two different ones of the first color resist elements 37, the second color resist elements 38, and the third color resist elements 39 are disposed in one brightening area A21, specifically, one first color resist element 37 and one second color resist element 38, or one second color resist element 38 and one third color resist element 39, or one third color resist element 39 and one first color resist element 37 are disposed in one brightening area A21. The two first color resist elements 37 are respectively located in two adjacent brightening areas A21 of the sub-pixel area A1 where the first light-emitting element 333a is located, the two second color resist elements 38 are respectively located in two adjacent brightening areas A21 of the sub-pixel area A1 where the second light-emitting element 333b is located, and the two third color resist elements 39 are respectively located in two adjacent brightening areas A21 of the sub-pixel area A1 where the third light-emitting element 333c is located. The orthographic projection of the first light-emitting element 333a on the encapsulation layer 34 is located between the orthographic projections of the two first color resist elements 37 on the encapsulation layer 34, the orthographic projection of the second light-emitting element 333b on the encapsulation layer 34 is located between the orthographic projections of the two second color resist elements 38 on the encapsulation layer 34, and the orthographic projection of the third light-emitting element 333c on the encapsulation layer 34 is located between the orthographic projections of the two third color resist elements 39 on the encapsulation layer 34.

The first brightening light is red light, the second brightening light is green light, and the third brightening light is blue light.

[0083] It can be understood that the first display light emitted by the sub-pixel region A1 where the first light-emitting element 333a is located is the same color as the first brightening light emitted by parts of the two adjacent brightening areas A21 of the sub-pixel region A1, that is, the light-emitting area emitting red light is increased.

The display panel 30 also includes a plurality of light-emitting components 33, each of the light-emitting components 33 includes a pixel defining layer 331, and the pixel defining layer 331 is provided with a plurality of accommodating spaces 331b penetrating the pixel defining layer 331, and one of the accommodating spaces 331b is located in one of the brightening regions A21. Each of the light-emitting components 33 also includes a plurality of reflective elements 336, a plurality of light-dense elements 337, and a plurality of first light-sparse elements 338, and one of the reflective elements 336 is disposed in one of the accommodating spaces 331b, and the reflective elements 336 are respectively connected to the inner walls of the accommodating spaces 331b. One optically dense element 337 is disposed in one of the accommodating spaces 331b and is located on one side of the reflective element 336. The optically dense element 337 is spaced apart from the inner wall of the accommodating space 331b. One first optically sparse element 338 is disposed in the accommodating space 331b and is located on the peripheral side of the optically dense element 337. The first optically sparse element 338 is connected to the peripheral side surface of the optically dense element 337 and the inner wall of the accommodating space 331b respectively. Both the optically dense element 337 and the first optically sparse element 338 are light-transmissive, and the refractive index of the optically dense element 337 is greater than the refractive index of the first optically sparse element 338.

Therefore, the technical solution of the present application enables the brightening area A21 to emit light, that is, at least part of the peripheral area of ​​the sub-pixel area A1 emits light, thereby increasing the effective aperture ratio of the display panel 30, that is, increasing the ratio of the area of ​​the light-emitting surface of the display panel 30 to the area of ​​the light-emitting side of the display panel 30. At the same time, the light emitted by the brightening area A21 also increases the display brightness of the display panel 30 , thereby improving the display effect of the display panel 30 .Moreover, the brightening area A21 utilizes ambient light to emit light, and the brightening area A21 increases the display brightness of the display panel 30 without increasing the power consumption of the display panel 30 , which is beneficial to reducing the use cost of the display panel 30 .
