[0041] The technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present application. Obviously, the described embodiments are only a part of the embodiments of the present application, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present application without creative efforts shall fall within the protection scope of the present application.

[0042] The display panel provided by the embodiment of the present application includes:

[0043] The light-emitting layer 2 includes a first light-emitting surface 22 and a second light-emitting surface 23. The light emitted from the first light-emitting surface 22 is the first light 24, and the light emitted from the second light-emitting surface 23 is the second light 25. The propagation directions of the first light 24 and the second light 25 are different;

[0044] The functional module 5 is disposed on the second light-emitting surface 23. The functional module 5 is configured to make at least a part of the second light 25 emitted from the second light-emitting surface 23 become the third light 214 after passing through the functional module 5;

[0045] Wherein, the propagation direction of the third light 214 is substantially the same as that of the first light 24.

[0046] It should be noted that as Figure 2 shown, the display panel provided by this solution can be a display curved panel, such as a curved screen. Correspondingly, the first light-emitting surface 22 of the light-emitting layer 2 can be the flat light-emitting surface of the display curved panel light-emitting layer, and the second light-emitting surface 22 of the light-emitting layer 2 can be the curved light-emitting surface of the display curved panel light-emitting layer. The first light-emitting surface 22 of the light-emitting layer 2 and the second light-emitting surface 23 may not be coplanar, and the propagation directions of the light emitted from the first light-emitting surface 22 and the second light-emitting surface 23 of the light-emitting layer 2 are different. For example, most of the first light 24 is emitted along the normal direction of the first light-emitting surface 22, and most of the second light 25 is emitted along the normal direction of the second light-emitting surface 23;

[0047] The functional module 5 is disposed at least on the second light-emitting surface 23. The functional module 5 is configured to adjust at least a part of the second light rays 25 emitted from the second light-emitting surface 23 into third light rays 214. Among them, the light rays emitted from the second light-emitting surface 23 may include: divergent second light rays and direct second light rays. The propagation direction of the divergent second light rays may form an acute angle or an obtuse angle with the second light-emitting surface 23, and the propagation direction of the direct second light rays may form a right angle with the second light-emitting surface 23. In this display panel, actually, the direct second light rays and part of the divergent second light rays emitted from the second light-emitting surface 23 are adjusted by the functional module 5 into third light rays 214. For details, see the following description. That is, the propagation directions of these second light rays emitted from the second light-emitting surface 23 are changed after being adjusted by the functional module 5, that is, the emission angles of these second light rays are changed, so that the propagation directions of these second light rays can be deflected towards the propagation direction of the first light rays 24, so that they can be basically the same as the propagation direction of the first light rays 24. Here, basically the same means that the propagation direction of the second light rays after adjustment is the same as or slightly different from the propagation direction of the first light rays 24, that is, the emission angle of the second light-emitting surface 23 is basically the same as the emission angle of the first light-emitting surface 22, which can achieve the effect that the brightness of the second light-emitting surface 23 is close to the brightness of the first light-emitting surface when the user looks directly at the first light-emitting surface 22 of the display panel, that is, to optimize the brightness of the second light-emitting surface 23 of the display panel, so as to improve the consistency of the brightness of multiple light-emitting surfaces when looking directly at the display panel, thereby helping to improve the user experience.

[0048] In addition, the functional module 5 may be a light ray adjustment layer. In addition, as Figure 2 shown, the display panel may further include: a display screen driving layer (TFT), a thin film encapsulation layer (TFE), and a touch function layer (DOT). Among them, the display screen driving layer 1, the light-emitting layer 2, the thin film encapsulation layer 3, the touch function layer 4, and the light ray adjustment layer may be stacked and disposed in sequence. The light ray adjustment layer may be correspondingly distributed at least with respect to the second light-emitting surface 23 of the light-emitting layer 2. The thin film encapsulation layer 3 may be used to prevent air and moisture from entering the light-emitting layer 2.

[0049] As can be seen from the above technical solutions, for the display panel provided in the embodiments of the present application, at least part of the second light rays emitted by the second light-emitting surface 23 become third light rays 214 whose propagation directions are substantially the same as that of the first light rays 24 after passing through the functional module 5. That is, the propagation directions of at least part of the second light rays are adjusted by the functional module 5, so that the propagation directions of part of the second light rays after adjustment can be deflected towards the propagation direction of the first light rays 24, so that the propagation directions of the second light rays after adjustment can be substantially the same as that of the first light rays 24. That is, the emission angles of at least part of the second light rays are changed by the functional module 5, and the brightest viewing angle of the second light-emitting surface can be deflected towards the first light-emitting surface, and the effect that the brightness of the second light-emitting surface is close to that of the first light-emitting surface when the user faces the first light-emitting surface of the display panel directly can be achieved. In this way, the brightness consistency of multiple light-emitting surfaces when facing the display panel directly is improved, which can help to enhance the user experience.

[0050] In some embodiments, as Figure 2 shown, the light rays emitted by the second light-emitting surface 23 include: the first part of the second light rays 211, and the propagation direction of the first part of the second light rays 211 forms an acute angle or an obtuse angle with the second light-emitting surface 23;

[0051] The first part of the second light rays 211 are reflected by the functional module 5 to become the third light rays 214, or become the fourth light rays 219;

[0052] Among them, the propagation direction of the fourth light rays 219 is deflected towards the normal line of the second light-emitting surface 23.

[0053] It should be noted that, as Figure 2 shown, the divergent second light rays as described above may include: the first part of the second light rays 211, the second part of the second light rays 212, the fourth part of the second light rays 217, and the fifth part of the second light rays 218; among them, the first part of the second light rays 211, the second part of the second light rays 212, the fourth part of the second light rays 217, and the fifth part of the second light rays 218 may be distributed around the normal line of the second light-emitting surface 23. The first part of the second light rays 211 are far from the normal line of the first light-emitting surface 22, and the second part of the second light rays 212 are distributed opposite to the first part of the second light rays 211 and are close to the normal line of the first light-emitting surface 22. Correspondingly, when facing the display panel directly, the brightness formed by the first part of the second light rays 211 has the largest difference from the brightness of the first light-emitting surface, and the brightness formed by the second part of the second light rays 212 has the smallest difference from the brightness of the first light-emitting surface. The fourth part of the second light rays 217 and the fifth part of the second light rays 218 are distributed opposite to each other and are respectively between the first part of the second light rays 211 and the second part of the second light rays 212.

[0054] In some embodiments, as Figure 2As shown, the second light-emitting surface 23 can be located on the right side of the first light-emitting surface 22. Correspondingly, the first part of the second light rays 211 can be diverging second light rays directed to the right, the second part of the second light rays 212 can be diverging second light rays directed to the left, and the fourth part of the second light rays 217 can be diverging second light rays directed forward (as shown in Figure 3 ), and the fifth part of the second light rays 218 can be diverging second light rays directed backward (as shown in Figure 3 ); of course, the second light-emitting surface 23 can also be located on the left side of the first light-emitting surface 22. For example, when the display panel is a double-curved screen, correspondingly, the first part of the second light rays 211 can be diverging second light rays directed to the left, and the second part of the second light rays 212 can be diverging second light rays directed to the right.

[0055] In some embodiments, as shown in Figure 2 , after the first part of the second light rays 211 is reflected by the functional module 5, it becomes the third light rays 214. As shown in Figure 3 , the fourth part of the second light rays 217 can be reflected by the functional module 5 to become the fourth light rays 219, and the fifth part of the second light rays 218 can be reflected by the functional module 5 to become the sixth light rays 220; the propagation direction of the sixth light rays 220 can also be deflected towards the normal of the second light-emitting surface 23. That is to say, after the first part of the second light rays 211 is reflected and adjusted by the functional module 5, it becomes the third light rays 214 whose propagation direction is basically the same as that of the first light rays 24. The diverging second light rays emitted by the second light-emitting surface 23 and away from the normal of the first light-emitting surface 22 become the third light rays 214 whose propagation direction is basically the same as that of the first light rays 24 after being reflected and adjusted by the functional module 5. This can help improve the brightness consistency between the originally darker positions of the second light-emitting surface 23 and the brightness of the first light-emitting surface.

[0056] In an alternative embodiment, as shown in Figure 3 , the fourth part of the second light rays 217 can be reflected by the functional module 5 to become the fourth light rays 219 whose propagation direction is deflected towards the normal of the second light-emitting surface 23, and the fifth part of the second light rays 218 can be reflected by the functional module 5 to become the sixth light rays 220 whose propagation direction is deflected towards the normal of the second light-emitting surface 23. This can make the fourth part of the second light rays 217 and the fifth part of the second light rays 218 approach the normal of the second light-emitting surface 23 respectively, so that the second light-emitting surface 23 can achieve light concentration, and further improve the brightness of the second light-emitting surface 23.

[0057] In some embodiments, as shown in Figure 2As shown, the light rays emitted by the second light-emitting surface 23 include: a second part of the second light rays 212, and the propagation direction of the second part of the second light rays 212 forms an acute or obtuse angle with the second light-emitting surface 23 and is biased towards the propagation direction of the first light rays 24;

[0058] After the second part of the second light rays 212 is avoided by the functional module 5, the propagation direction remains unchanged. Among them, as described above, the second part of the second light rays 212 can be divergent second light rays close to the normal line of the first light-emitting surface 22, that is, the divergent second light rays that can be directed to the left or right; of course, the propagation direction of the second part of the second light rays 212 is biased towards the propagation direction of the first light rays 24, that is, biased towards the normal line of the first light-emitting surface 22, that is, when the display panel is viewed head-on, the brightness of the second part of the second light rays 212 is similar to the brightness of the first light-emitting surface. In this way, the functional module 5 can not need to adjust the propagation direction of the second part of the second light rays 212, that is, the functional module 5 can avoid the propagation direction of the second part of the second light rays 212 to ensure that the second part of the second light rays 212 can be emitted in the original propagation direction.

[0059] In some embodiments, as Figure 2 shown, the light rays emitted by the second light-emitting surface 23 include: a third part of the second light rays 213, and the propagation direction of the third part of the second light rays 213 forms a right angle with the second light-emitting surface 23. After the third part of the second light rays 213 is refracted by the functional module 5, it becomes the third light rays 214. Among them, as described above, the third part of the second light rays 213 can be the direct second light rays emitted by the second light-emitting surface 23, that is, the direct second light rays emitted by the second light-emitting surface 23 become the third light rays 214 after being refracted by the functional module 5, which can make the direct second light rays with a large brightness difference from the first light-emitting surface become the third light rays 214 whose propagation direction deflects towards the normal line of the first light-emitting surface 22 after being refracted and adjusted by the functional module 5, thereby helping to improve the consistency of the brightness at the normal line position of the second light-emitting surface 23 and the brightness of the first light-emitting surface.

[0060] That is to say, the display panel provided by this solution can be used to respectively adjust the propagation directions of the divergent second light rays and the direct second light rays far from the normal line of the first light-emitting surface 22 through the reflection and / or refraction of the functional module, and can make the propagation directions of these second light rays deflect towards the normal line of the first light-emitting surface 22, so as to achieve the effect that when the user views the display panel head-on, the brightness of the second light-emitting surface 23 is similar to the brightness of the first light-emitting surface.

[0061] In some embodiments, as Figure 2 shown, the functional module 5 can also be disposed on the first light-emitting surface 22, and a part of the first light rays emitted by the first light-emitting surface 22 becomes the fifth light rays 215 after being reflected by the functional module 5;

[0062] Among them, the propagation direction of the fifth light ray 215 deflects towards the normal line of the first light-emitting surface 22. Similarly, the light rays emitted by the first light-emitting surface 22 may include: a divergent first light ray and a direct first light ray. The propagation direction of the divergent first light ray may form an acute angle or an obtuse angle with the first light-emitting surface 22, and the propagation direction of the direct first light ray may form a right angle with the first light-emitting surface 22. The above-mentioned partial first light rays refer to the divergent first light rays. Of course, the divergent first light rays can also surround the normal line of the first light-emitting surface 22 and may include: a first part of the first light ray, a second part of the first light ray, a third part of the first light ray, and a fourth part of the first light ray. The first part of the first light ray and the second part of the first light ray may be distributed relatively. The third part of the first light ray and the fourth part of the first light ray may be distributed relatively and may be respectively between the first part of the first light ray and the second part of the first light ray. The first part of the first light ray may be a divergent first light ray facing right, the second part of the first light ray may be a divergent first light ray facing left, the third part of the first light ray may be a divergent first light ray facing forward, and the fourth part of the first light ray may be a divergent first light ray facing backward. Moreover, as Figure 2 shown, the first part of the first light ray becomes the fifth light ray 215 after being reflected by the functional module 5, the second part of the first light ray becomes the seventh light ray 216 after being reflected by the functional module 5. The propagation directions of the fifth light ray 215 and the seventh light ray 216 may both deflect towards the normal line of the first light-emitting surface 22. The third part of the first light ray becomes the eighth light ray ( Figure 2 not shown in the figure) whose propagation direction deflects towards the normal line of the first light-emitting surface 22 after being reflected by the functional module 5. The fourth part of the first light ray may be the same, which will not be elaborated here. That is to say, the divergent first light rays emitted by the first light-emitting surface 22 can become light rays whose propagation directions deflect towards the normal line of the first light-emitting surface 22 after being reflected and adjusted by the functional module 5, that is, their propagation directions can approach the normal line of the first light-emitting surface 22 after being reflected and adjusted by the functional module 5, so as to achieve the condensing of the first light-emitting surface 22 and further improve the brightness of the first light-emitting surface 22.

[0063] In some embodiments, as Figure 2 shown, the light-emitting layer 2 has a plurality of light-emitting units 21 in the area covered by the second light-emitting surface 23, and the light rays emitted by each light-emitting unit 21 are second light rays 25;

[0064] The functional module 5 includes a plurality of functional units 51;

[0065] The plurality of functional units 51 are distributed in one-to-one correspondence with at least a part of the plurality of light-emitting units 21, and at least a part of the second light rays 25 emitted by each light-emitting unit 21 become third light rays 214 after passing through the corresponding functional unit 51.

[0066] It should be noted that a plurality of light-emitting units 21 may be evenly distributed in the area covered by the second light-emitting surface 23 of the light-emitting layer 2, asFigure 1 Among the multiple light-emitting units 21 shown, from left to right, they can be alternately and sequentially a red sub-pixel (EL-R), a green sub-pixel (EL-G), and a blue sub-pixel (EL-B); and as described above, the functional module 5 can be a light adjustment layer, such as Figure 2 shown, multiple functional units 51 within the light adjustment layer can be distributed one-to-one vertically corresponding to at least a part of the multiple light-emitting units 21. The light emitted by each light-emitting unit 21 can include: a first part of the second light 211, a second part of the second light 212, a third part of the second light 213, a fourth part of the second light 217, and a fifth part of the second light 218; the first part of the second light 211 emitted by each light-emitting unit 21 becomes the third light 214 after being reflected and adjusted by the corresponding functional unit 51, and the third part of the second light 213 emitted by each light-emitting unit 21 becomes the third light 214 after being refracted and adjusted by the corresponding functional unit 51; in addition, the second part of the second light 212 emitted by each light-emitting unit 21 is emitted along the original propagation direction after being avoided by the corresponding functional unit 51, the fourth part of the second light 217 emitted by each light-emitting unit 21 becomes the fourth light 219 after being reflected and adjusted by the corresponding functional unit 51, and the fifth part of the second light 218 emitted by each light-emitting unit 21 becomes the sixth light 220 after being reflected and adjusted by the corresponding functional unit 51.

[0067] That is to say, the functional module 5 can include multiple functional units 51 that are provided in a one-to-one matching manner for the multiple light-emitting units 21. At least a part of the second light emitted by each light-emitting unit 21 changes the propagation direction through the corresponding functional unit 51, which can deflect the propagation direction of these second lights towards the normal of the first light-emitting surface 22 and become the third light 214. Each functional unit 51 can perform the function of adjusting the propagation direction of the second light, and thus the function of the entire functional module 5 adjusting the propagation direction of part of the second light can be realized, which can make the adjustment of the second light more effective and reliable. Of course, the functional unit 51 can also be equivalent to a light adjustment unit.

[0068] In some embodiments, such as Figure 2 shown, the functional unit 51 surrounds the light-emitting unit 21;

[0069] As described above, the light emitted by the light-emitting unit 21 includes: a first part of the second light 211;

[0070] The first part of the second light 211 becomes the third light 214 after being reflected by the first inner side surface of the functional unit 51; or the first part of the second light 211 becomes the fourth light 219 after being reflected by the second inner side surface or the third inner side surface of the functional unit 51;

[0071] Among them, as described above, the second inner side surface and the third inner side surface of the functional unit 51 are distributed oppositely and are both adjacent to the first inner side surface.

[0072] In some embodiments, each functional unit 51 can surround the corresponding light-emitting unit 21 and can be located above the corresponding light-emitting unit 21. Each functional unit 51 can have a first inner side surface, a second inner side surface, a third inner side surface, and a fourth inner side surface surrounding the corresponding light-emitting unit 21. The first inner side surface is away from the normal line of the first light-emitting surface 22, the fourth inner side surface is close to the normal line of the first light-emitting surface 22, and the first inner side surface and the fourth inner side surface are distributed oppositely. The second inner side surface and the third inner side surface are distributed oppositely and are respectively located between the first inner side surface and the fourth inner side surface. That is, the first inner side surface, the second inner side surface, the fourth inner side surface, and the third inner side surface of each functional unit 51 can sequentially surround the corresponding light-emitting unit 21; among them, as Figure 2 shown, the first inner side surface of the functional unit 51 can be the inner right side surface, the second inner side surface can be the inner front side surface, the fourth inner side surface can be the inner left side surface, and the third inner side surface can be the inner rear side surface; the first part of the second light rays 211 of each light-emitting unit 21 becomes the third light rays 214 after being reflected by the first inner side surface of the corresponding functional unit 51, the fourth part of the second light rays 217 becomes the fourth light rays 219 after being reflected by the second inner side surface of the corresponding functional unit 51, and the fifth part of the second light rays 218 becomes the sixth light rays 220 after being reflected by the third inner side surface of the corresponding functional unit 51. For example, the diverging second light rays of each light-emitting unit 21 to the right become the third light rays 214 after being reflected by the inner right side surface of the corresponding functional unit 51, the diverging second light rays forward become the fourth light rays 219 after being reflected by the inner front side surface of the corresponding functional unit 51, and the diverging second light rays backward become the sixth light rays 220 after being reflected by the inner rear side surface of the corresponding functional unit 51.

[0073] That is to say, the functional unit 51 can be disposed around the light-emitting unit 21 to facilitate the reflection adjustment of the divergent second light rays in different directions (such as right, forward, and backward) of the light-emitting unit 21, for changing the propagation directions of the divergent second light rays in different directions, so that the divergent second light rays in different directions can be deflected or converged. Among them, the first partial second light rays 211 of each light-emitting unit 21 become the third light rays 214 after being reflected by the first inner side surface of the corresponding functional unit 51, which can make the divergent second light rays emitted from each light-emitting unit 21 away from the normal line of the first light-emitting surface 22 become the third light rays 214 with the propagation directions deflected toward the normal line of the first light-emitting surface 22 after being reflected and adjusted by the first inner side surface of the corresponding functional unit 51, that is, the first partial second light rays 211 with the largest difference in the propagation direction from the first light ray 24 of each light-emitting unit 21 become the third light rays 214 after being reflected and adjusted by the first inner side surface of the corresponding functional unit 51. In this way, when an observer views the display panel from any perspective, the perceived difference in brightness between the first light-emitting surface 22 and the second light-emitting surface 23 can be significantly reduced, achieving a more uniform visual experience. Moreover, the fourth partial second light rays 217 of each light-emitting unit 21 become the fourth light rays 219 after being reflected by the second inner side surface of the corresponding functional unit 51, and the fifth partial second light rays 218 of each light-emitting unit 21 become the sixth light rays 220 after being reflected by the third inner side surface of the corresponding functional unit 51, which can make the fourth partial second light rays 217 and the fifth partial second light rays 218 of each light-emitting unit 21 approach the normal line of the second light-emitting surface 23 respectively, so that the second light-emitting surface 23 can achieve light condensation, further enhancing the brightness of the second light-emitting surface 23.

[0074] Furthermore, as described above, the light rays emitted by the light-emitting unit 21 include: the second partial second light rays 212;

[0075] The propagation direction of the second partial second light rays 212 remains unchanged after being bypassed by the fourth inner side surface of the functional unit 51, that is, they are emitted along the original propagation direction;

[0076] Among them, as described above, the fourth inner side surface of the functional unit 51 is distributed opposite to the first inner side surface, and both are adjacent to the second inner side surface and the third inner side surface. As Figure 2 shown, the second partial second light rays 212 emitted by each light-emitting unit 21 are emitted along the original propagation direction after being bypassed by the fourth inner side surface of the corresponding functional unit 51; for example, as Figure 2As shown, each light-emitting unit 21 emits divergent second light rays directed to the left. After being deflected by the inner left side surface of the corresponding functional unit 51, the light rays are emitted along their original propagation directions. That is, the fourth inner side surface of each functional unit 51 can deflect the emission of the second part of the second light rays 212 of the corresponding light-emitting unit 21, ensuring that the second part of the second light rays 212 of each light-emitting unit 21 are emitted in their original propagation directions. In addition, the fourth inner side surface of the functional unit 51 can be parallel to the propagation direction of the second part of the second light rays 212. Among them, when the light-emitting unit 21 is located on the right side of the normal line of the first light-emitting surface 22, the fourth inner side surface of the corresponding functional unit 51 and the second light-emitting surface 23 can form a first obtuse angle. The propagation direction of the second part of the second light rays 212 of this light-emitting unit 21 and the second light-emitting surface 23 can form a second obtuse angle. The first obtuse angle is greater than or equal to the second obtuse angle, ensuring that the fourth inner side surface of the functional unit 51 can achieve the effect of deflecting the second part of the second light rays 212. Of course, at this time, the propagation direction of the first part of the second light rays 211 of this light-emitting unit 21 and the second light-emitting surface 23 can form an acute angle, the propagation direction of the fourth part of the second light rays 217 and the second light-emitting surface 23 can also form an acute angle, and the propagation direction of the fifth part of the second light rays 218 and the second light-emitting surface 23 can also form an obtuse angle. When the light-emitting unit 21 is located on the left side of the normal line of the first light-emitting surface 22, the fourth inner side surface of the corresponding functional unit 51 and the second light-emitting surface 23 can form a first acute angle. The propagation direction of the second part of the second light rays 212 of this light-emitting unit 21 and the second light-emitting surface 23 can form a second acute angle. The first acute angle is less than or equal to the second acute angle, ensuring that the fourth inner side surface of the functional unit 51 can achieve the effect of deflecting the second part of the second light rays 212. Of course, at this time, the propagation direction of the first part of the second light rays 211 of this light-emitting unit 21 and the second light-emitting surface 23 can form an obtuse angle, the propagation direction of the fourth part of the second light rays 217 and the second light-emitting surface 23 can form an acute angle, and the propagation direction of the fifth part of the second light rays 218 and the second light-emitting surface 23 can form an obtuse angle.

[0077] In addition, as described above, the functional module 5 can also be disposed on the first light-emitting surface 22. A part of the first light rays 24 emitted from the first light-emitting surface 22 are reflected by the functional module 5 and become the fifth light rays 215. Among them, as Figure 2 shown, the light-emitting layer 2 can also have multiple light-emitting units 21 in the area covered by the first light-emitting surface 22. The light rays emitted by each light-emitting unit 21 are the first light rays 24.

[0078] The functional module 5 disposed on the first light-emitting surface 22 can also include multiple functional units 51.

[0079] The multiple functional units 51 are distributed in one-to-one correspondence with at least a part of the multiple light-emitting units 21. A part of the first light rays emitted by each light-emitting unit 21 are reflected by the corresponding functional unit 51 and become the fifth light rays 215.

[0080] It should be noted that, in this embodiment, a plurality of light-emitting units 21 may be evenly distributed in the area covered by the first light-emitting surface 22 of the light-emitting layer 2. For example, Figure 1 as shown, the plurality of light-emitting units 21 from left to right may be alternately and sequentially a red sub-pixel (EL-R), a green sub-pixel (EL-G), and a blue sub-pixel (EL-B); as described above, the functional module 5 may be a light-adjusting layer, such as Figure 2 shown, and a plurality of functional units 51 in the light-adjusting layer are distributed in one-to-one correspondence with at least a part of the plurality of light-emitting units 21 up and down. The light emitted by each light-emitting unit 21 may include: a first part of the first light, a second part of the first light, a third part of the first light, a fourth part of the first light, and a fifth part of the first light; and as Figure 2 shown, the functional unit 51 may also surround the light-emitting unit 21; the first part of the first light emitted by the light-emitting unit 21 becomes the fifth light 215 after being reflected by the first inner side surface of the functional unit 51, the second part of the first light becomes the seventh light 216 after being reflected by the fourth inner side surface of the functional unit 51, the third part of the first light becomes the eighth light after being reflected by the second inner side surface of the functional unit 51, and the fourth part of the first light becomes the ninth light after being reflected by the third inner side surface of the functional unit 51; wherein, the propagation directions of the seventh light 216, the eighth light, and the ninth light can all deflect towards the normal line of the first light-emitting surface 22, so as to realize the light condensation of the light diverging from the first light-emitting surface 22, and the brightness of the first light-emitting surface can be further improved. Of course, the third part of the first light (direct first light) emitted by the light-emitting unit 21 is emitted along the original propagation direction after passing through the corresponding functional unit 51. That is to say, as Figure 2 shown, the structures of the functional units 51 of the functional module 5 provided on the first light-emitting surface 22 and the functional units 51 of the functional module 5 provided on the second light-emitting surface 23 may be different; wherein, the fourth inner side surface of the functional unit 51 of the functional module 5 provided on the first light-emitting surface 22 can be used to reflect the second part of the first light, and the fourth inner side surface of the functional unit 51 of the functional module 5 provided on the second light-emitting surface 23 can be used to avoid the second part of the second light.

[0081] Furthermore, the functional unit 51 includes a prism, and the prism is used to refract and / or reflect the received light. Among them, as Figure 2 shown, according to the above, each prism can surround the corresponding light-emitting unit 21, and is located above the touch function layer 4, and the first inner side wall, the second inner side wall, and the third inner side wall of each prism located above the second light-emitting surface 23 can all be reflective inner side walls, and the fourth inner side wall can be an avoidance inner side wall, and the first inner side wall, the second inner side wall, the third inner side wall, and the fourth inner side wall of each prism located above the first light-emitting surface 22 can all be reflective inner side walls.

[0082] In addition, for the convenience of arranging multiple prisms, a layer of prisms can be arranged above the touch function layer 4 and corresponding to the second light-emitting surface 23. Then, a plurality of grooves (which may not penetrate) can be formed in this layer of prisms, and the plurality of grooves are distributed in one-to-one correspondence with the plurality of light-emitting units 21 of the light-emitting layer 2 within the second light-emitting surface 23. Among them, the four inner side walls (all inclined walls) of each groove can surround the corresponding light-emitting unit 21 and respectively serve as the first inner side wall, the second inner side wall, the third inner side wall, and the fourth inner side wall of the functional unit 51, so that the four inner side walls of each groove achieve the corresponding reflection effect or avoidance effect, and the lower wall of each groove can be used to refract the third part of the second light (direct second light) of the corresponding light-emitting unit 21. That is to say, the above design enables the multiple prisms to be connected and arranged, which is not only convenient for arranging the multiple prisms but also convenient for stacking the multiple prisms. In addition, when the functional unit 51 is arranged on the first light-emitting surface 22, the above method can also be adopted, but the plurality of grooves formed in this layer of prisms can be penetrated to avoid the lower wall of the groove interfering with the emission of the direct first light. Moreover, the above layer of prisms can be made of a low-refraction material, and the low-refraction material can be a common glue material or epoxy resin.

[0083] In addition, to achieve a high light-concentrating effect of the functional module, as Figure 2 shown, a layer of high-refraction filling material can be further arranged or covered on this layer of prisms, so that the top surface of the functional module 5 is finally a flat surface. Among them, the high-refraction filling material can be selected as epoxy resin added with uniformly distributed zirconia powder, and the higher the content of the zirconia powder, the higher the refractive index of the high-refraction filling material, but it will become more brittle accordingly, so it needs to be adjusted to a suitable ratio. Of course, the high-refraction filling material can also be obtained by adjusting a high-refraction glue material.

[0084] That is to say, this solution can optimize the propagation direction of the second light emitted from the second light-emitting surface 23 through the micro-prism module. Among them, this layer of prisms can be the low-refraction layer, and the low-refraction layer is provided with a plurality of grooves that respectively surround the plurality of light-emitting units 21, which are used to realize the reflection or avoidance of the light diverged by the light-emitting units 21. Correspondingly, the high-refraction filling material can be the high-refraction layer.

[0086] A light-emitting layer 2, including a first light-emitting surface 22 and a second light-emitting surface 23, the light emitted from the first light-emitting surface 22 is the first light 24, the light emitted from the second light-emitting surface 23 is the second light, and the propagation directions of the first light 24 and the second light are different;

[0087] The functional module 5 is disposed on the second light-emitting surface 23. The functional module 5 is configured to cause at least part of the second light rays emitted from the second light-emitting surface 23 to become third light rays 214 after passing through the functional module 5;

[0088] Among them, the propagation directions of the third light rays 214 and the first light rays 24 are substantially the same. Since the display panel included in this electronic device is the same as the display panel described above, it thus has corresponding beneficial effects, which can be specifically referred to the previous description and will not be elaborated here.
