Description

Display panel and display device

[0001] The present application claims priority from the Chinese patent application No. 202411365603.1 filed on September 27, 2024, and entitled "Display panel and display device", the content of which is incorporated herein by reference in its entirety. TECHNICAL FIELD

[0002] The present application relates to the technical field of display, in particular to a display panel and a display device. BACKGROUND

[0003] Users have privacy needs when using display products in public places. Although the anti-peeping film meets the privacy needs of users, after the anti-peeping film is pasted, only the user directly facing the screen can see the content on the screen, which also limits the use environment of the display product after the film is pasted. Therefore, the research on the active anti-peeping scheme is also one of the technical problems that need to be overcome by the current display product. The current active anti-peeping scheme will cause an increase in display power consumption. SUMMARY

[0004] Embodiments of the present application provide a display panel and a display device to solve the technical problem of reducing display power consumption in the active anti-peeping scheme.

[0005] In a first aspect, embodiments of the present application provide a display panel, comprising:

[0006] a substrate and a display layer located on one side of the substrate, the display layer comprising a pixel definition layer and a plurality of light emitting devices, the pixel definition layer comprising a first opening and a second opening, the light emitting devices comprising a first light emitting device and a second light emitting device, the first light emitting device being located in the first opening, and the second light emitting device being located in the second opening;

[0007] a light blocking structure located on a side of the display layer away from the substrate; at least part of the light blocking structure is located between the projections of the adjacent two light emitting devices on the substrate; along a first direction, the distance between the light blocking structure and the first opening is less than the distance between the light blocking structure and the second opening, and the first direction is parallel to the plane in which the substrate is located;

[0008] a light guiding structure located on a side of the display layer away from the substrate; along a direction perpendicular to the plane in which the substrate is located, the first light emitting device and the light guiding structure at least partially overlap, and / or the second light emitting device and the light guiding structure at least partially overlap.

[0009] In a second aspect, based on the same inventive concept, embodiments of the present application provide a display device comprising the display panel provided by any of the embodiments of the present application.

[0010] The display panel and the display device provided by the embodiment of the present application have the following beneficial effects: in the embodiment of the present application, the distance between the light-blocking structure and the opening of the pixel definition layer is set, so that the light-emitting angle of the first light-emitting device is smaller than the light-emitting angle of the second light-emitting device. In the application, the first light-emitting device can be used as a privacy pixel, and the second light-emitting device can be used as a shared pixel. When the first light-emitting device is lit, active privacy is realized. The light guide structure is arranged on the side of the display layer away from the substrate. In the direction perpendicular to the plane where the substrate is located, the first light-emitting device at least partially overlaps with the light guide structure, and / or the second light-emitting device at least partially overlaps with the light guide structure. The light guide effect of the light guide structure can reduce the power consumption of the display panel. For example, the light guide structure overlapping with the first light-emitting device converges light, and more light with a large angle is emitted from the normal direction, thereby increasing the brightness of the first light-emitting device and reducing the power consumption of the display panel in the privacy mode. The light guide structure overlapping with the second light-emitting device diffuses light, so that more light is emitted at a large angle, thereby increasing the brightness when a user views at a large angle and reducing the power consumption of the display panel in the shared mode.

[0038] Fig. 1 is a schematic view of a display panel according to an embodiment of the application, and Fig. 2 is a schematic view of a cross section along the line A-A' in Fig. 1. As shown in Fig. 1, the light emitting device 1 in the display panel includes first light emitting device 10 and second light emitting device 20. The first light emitting device 10 includes first color first light emitting device 11, second color first light emitting device 12 and third color first light emitting device 13. The second light emitting device 20 includes first color second light emitting device 21, second color second light emitting device 22 and third color second light emitting device 23. The first color first light emitting device 11, the second color first light emitting device 12 and the third color first light emitting device 13 are one of a red light emitting device, a green light emitting device and a blue light emitting device, respectively. The first color second light emitting device 21 has the same color as the first color first light emitting device 11. The second color second light emitting device 22 has the same color as the second color first light emitting device 12. The third color second light emitting device 23 has the same color as the third color first light emitting device 13. The shape and arrangement of the light emitting device 1 in Fig. 1 are only schematic and do not limit the application. The shape of the light emitting device 1 in the embodiment of the application can be circular, rectangular or other polygonal, or irregular shape.

[0039] With reference to FIG. 2, the display panel includes a substrate 00, a display layer 01 located on one side of the substrate 00, a light-blocking structure 02 and a light-guiding structure 03 located on a side of the display layer 01 away from the substrate 00. The display layer 01 includes a pixel definition layer 011 and a plurality of light-emitting devices 1, the pixel definition layer 011 includes a first opening K1 and a second opening K2, a first light-emitting device 10 is located in the first opening K1, and a second light-emitting device 20 is located in the second opening K2. The first light-emitting device 10 and the second light-emitting device 20 each include a first electrode 1a, a light-emitting layer 1b, and a second electrode 1c, the first electrode 1a is an anode, and the second electrode 1c is a cathode. The display panel further includes a driving layer 04 and an encapsulation layer 05, the driving layer 04 is provided with a pixel circuit, the pixel circuit is electrically connected with the first electrode 1a and is used to drive the light-emitting device 1 to emit light. The encapsulation layer 05 is located on a side of the display layer 01 away from the substrate 00, and is used to isolate water and oxygen and protect the light-emitting device 1. Optionally, the encapsulation layer 05 includes at least one organic encapsulation layer and at least one inorganic encapsulation layer.

[0040] At least part of the light-blocking structure 02 is located between the projections of two adjacent light-emitting devices 1 on the substrate 00. The display panel further includes a light-filtering unit 06, which overlaps the light-emitting device 1 in a direction e perpendicular to the plane of the substrate 00. The light-blocking structure 02 is used to block light from entering the inside of the display panel, which can prevent the reflection of ambient light by the metal structure in the driving layer 04, thereby reducing the reflectivity of the display panel. The light-filtering unit 06 can also reduce the reflectivity of the display panel. In a first direction a, the distance between the light-blocking structure 02 and the first opening K1 is d1, and the distance between the light-blocking structure 02 and the second opening K2 is d2, d1 < d2, and the first direction a is parallel to the plane of the substrate 00. Since the light-blocking structure 02 has the function of blocking light, the distance between the light-blocking structure 02 and the opening of the pixel definition layer 011 affects the light-emitting angle of the light-emitting device 1. In the embodiment, the light-emitting angle of the first light-emitting device 10 is smaller than that of the second light-emitting device 20. That is, the light emitted by the second light-emitting device 20 can be emitted at a large angle, while the light-emitting angle of the light emitted by the first light-emitting device 10 is smaller. In application, the first light-emitting device 10 can be used as a privacy pixel, and the second light-emitting device 20 can be used as a shared pixel. By designing the distance between the first opening K1 and the light-blocking structure 02, and using the light-blocking structure 02 to block the lateral light emission of the first light-emitting device 10, the light emitted by the first light-emitting device 10 can be emitted substantially in the normal direction of the display panel (i.e., the direction e perpendicular to the plane of the substrate 00). Therefore, when the first light-emitting device 10 is lit, the user cannot view the light emitted by the first light-emitting device 10 in a large viewing angle direction, thereby achieving a privacy effect.

[0041] As shown in FIG. 2, along the direction e perpendicular to the plane where the substrate 00 is located, the first light emitting device 10 at least partially overlaps with the light guide structure 03, and the second light emitting device 20 at least partially overlaps with the light guide structure 03. The light guide structure 03 overlapping with the first light emitting device 10 is used to converge light, so that more light is emitted in the normal direction, thereby increasing the brightness of the first light emitting device 10 and reducing power consumption. The light guide structure 03 overlapping with the second light emitting device 20 is used to diffuse light, so that more light is emitted in a large angle, thereby increasing the brightness when viewed in a large angle and reducing power consumption.

[0042] As shown in FIG. 2, the first light emitting device 10 and the second light emitting device 20 respectively at least partially overlap with the light guide structure 03. In another embodiment, FIG. 3 is another cross-sectional view of the position of the tangent line A-A' in FIG. 1. As shown in FIG. 3, along the direction e perpendicular to the plane where the substrate 00 is located, the first light emitting device 10 at least partially overlaps with the light guide structure 03. No light guide structure 03 is arranged above the second light emitting device 20. In another embodiment, along the direction e perpendicular to the plane where the substrate 00 is located, the second light emitting device 20 at least partially overlaps with the light guide structure 03. No light guide structure 03 is arranged above the first light emitting device 10, which is not shown in the figure.

[0043] In the embodiment of the present application, the distance between the light blocking structure 02 and the opening of the pixel definition layer 011 is set to be smaller than the light emitting angle of the second light emitting device 20, so that the light emitting angle of the first light emitting device 10 is smaller than the light emitting angle of the second light emitting device 20. In application, the first light emitting device 10 can be used as a privacy pixel, and the second light emitting device 20 can be used as a shared pixel. When the first light emitting device 10 is lit, active privacy is achieved. The light guide structure 03 is arranged on the side of the display layer 01 away from the substrate 00. Along the direction e perpendicular to the plane where the substrate 00 is located, the first light emitting device 10 at least partially overlaps with the light guide structure 03, and / or the second light emitting device 20 at least partially overlaps with the light guide structure 03. The light guide effect of the light guide structure 03 can reduce the power consumption of the display panel. For example, the light guide structure 03 overlapping with the first light emitting device 10 converges light, so that more light is emitted in the normal direction, thereby increasing the brightness of the first light emitting device 10 and reducing the power consumption of the display panel in the privacy mode. The light guide structure 03 overlapping with the second light emitting device 20 diffuses light, so that more light is emitted in a large angle, thereby increasing the brightness when viewed in a large angle and reducing the power consumption of the display panel in the shared mode.

[0044] In some embodiments, the display panel comprises a first display mode and a second display mode; in the first display mode, the first light emitting device 10 emits light, and the second light emitting device 20 does not emit light; in the second display mode, the first light emitting device 10 emits light, and the second light emitting device 20 emits light. The first display mode is a privacy mode, and the second display mode is a sharing mode. Only the first light emitting device 10 emits light in the privacy mode, avoiding side light leakage and ensuring the privacy effect. In the sharing mode, both the first light emitting device 10 and the second light emitting device 20 emit light, which can meet the brightness requirement in the sharing mode and reduce power consumption. Since the first light emitting device 10 mainly emits light in the front direction, and the setting of the light guide structure 03 can increase the side light emission amount of the second light emitting device 20, the brightness difference between the front direction and the large viewing angle direction in the sharing mode is balanced, and the overall display effect is improved.

[0045] In some embodiments, as shown in FIG. 2, along the first direction a, the distance between the light blocking structure 02 and the first opening K1 is d1, and the distance between the light blocking structure 02 and the second opening K2 is d2, 2um≤d2-d1≤5um. In the embodiment of the present application, the difference between d2 and d1 satisfies a certain range, which can balance between the light emission angle difference setting requirement of the first light emitting device 10 and the second light emitting device 20 and the manufacturing process capability of the display panel. The second light emitting device 20 with a larger light emission angle and the first light emitting device 10 with a relatively smaller light emission angle are manufactured in the effective area space of the display panel, and the active privacy solution is realized.

[0046] In some embodiments, 1um≤d1≤2um, and 4um≤d2≤6um.

[0047] As shown in FIG. 2, the light blocking structure 02 is located on the side of the light guide structure 03 away from the light emitting device 1. In the embodiment of the present application, the light blocking effect of the light blocking structure 02 is utilized to set the distance between the light blocking structure 02 and the opening of the pixel definition layer 011, so that the light emission angle of the first light emitting device 10 is smaller than that of the second light emitting device 20. When the first light emitting device 10 is lit, the privacy effect can be achieved. The light guide structure 03 is arranged between the light emitting device 1 and the light blocking structure 02, and the light guide effect of the light guide structure 03 is utilized to reduce the power consumption of the display panel.

[0048] For the first light emitting device 10, the light emitted therefrom is first converged by the light guide structure 03, so that more light is emitted in the front direction, and then the light emitted in the large viewing angle direction is shielded by the light blocking structure 02, thereby achieving the privacy effect and increasing the brightness of the first light emitting device 10, which can reduce the power consumption of the display panel. The light blocking structure 02 is arranged on the side of the light guide structure 03 away from the light emitting device 1, which can meet the application requirement of the first light emitting device 10 as a privacy pixel.

[0049] For the second light emitting device 20, the light rays are diffused by the light guide structure 03, so that more light rays are emitted at a large angle. At the same time, the distance between the light blocking structure 02 and the second opening K2 is set to be relatively large, so that the light blocking structure 02 does not affect the light emission at a large viewing angle, thereby increasing the brightness of the second light emitting device 20 when viewed at a large viewing angle, and thus reducing power consumption. The light blocking structure 02 is arranged on the side of the light guide structure 03 away from the light emitting device 1, and is designed in combination with the distance between the light blocking structure 02 and the second opening K2, so as to meet the application requirements of the second light emitting device 20 as a shared pixel. In addition, when the first light emitting device 10 and the second light emitting device 20 are both provided with corresponding light guide structures 03, the space of the film layer where the light guide structures 03 are located can be reasonably utilized, so as to reduce power consumption in both the privacy mode and the sharing mode.

[0050] In some embodiments, as shown in FIG. 2, the light guide structure 03 includes a first light guide structure 031 and a second light guide structure 032; the first light emitting device 10 at least partially overlaps the first light guide structure 031, and the second light emitting device 20 at least partially overlaps the second light guide structure 032, in the direction e perpendicular to the plane of the substrate 00; the first light guide structure 031 includes a first refractive part 41 and a second refractive part 43 with different refractive indexes, and the first refractive part 41 is located on the side of the second refractive part 42 close to the substrate 00; the second light guide structure 032 includes a third refractive part 43 and a fourth refractive part 44 with different refractive indexes, and the third refractive part 43 is located on the side of the fourth refractive part 44 close to the substrate 00; wherein the materials of the first refractive part 41 and the third refractive part 43 are the same, and the materials of the second refractive part 42 and the fourth refractive part 44 are the same. In this embodiment, the first refractive part 41 and the third refractive part 43 can be manufactured in the same process, and the second refractive part 42 and the fourth refractive part 44 can be manufactured in the same process, that is, the first light guide structure 031 and the second light guide structure 032 can be manufactured at the same time when the display panel is manufactured. Not only can power consumption be reduced in both the privacy mode and the sharing mode, but also the process is simple.

[0051] In the embodiment of FIG. 2, the refractive index of the first refractive part 41 is less than the refractive index of the second refractive part 42, and the refractive index of the third refractive part 43 is less than the refractive index of the fourth refractive part 44. In other embodiments, the refractive index of the first refractive part 41 is greater than the refractive index of the second refractive part 42, and the refractive index of the third refractive part 43 is greater than the refractive index of the fourth refractive part 44, which will be illustrated in subsequent related embodiment figures.

[0052] In some embodiments, FIG. 4 is another schematic diagram of a cross section of a display panel provided by an embodiment of the present application, and FIG. 4 only shows a cross section of a region where the first light emitting device 10 is located. As shown in FIG. 4, the light guide structure 03 includes a first light guide structure 031, and the first light emitting device 10 at least partially overlaps the first light guide structure 031 along a direction e perpendicular to a plane where the substrate 00 is located. The first light guide structure 031 includes a first refractive part 41 and a second refractive part 42 having different refractive indexes, and the first refractive part 41 is located on a side of the second refractive part 42 close to the substrate 00. The first refractive part 41 has a first hollow V1, and at least part of the second refractive part 42 is located in the first hollow V1. The first hollow V1 at least partially overlaps the first light emitting device 10 along a direction perpendicular to the plane where the substrate 00 is located. In this embodiment, the first light guide structure 031 is formed by stacking the first refractive part 41 and the second refractive part 42 having different refractive indexes, and the interface between the first refractive part 41 and the second refractive part 42 has a reflecting effect on light, so that the large-angle light emitted by the first light emitting device 10 after being affected by the first light guide structure 031 can be deflected to the normal direction, so that the light converges, thereby increasing the amount of light emitted by the first light emitting device 10 to the normal direction. The first light emitting device 10 is applied as a peep-proof pixel, the light blocking structure 02 blocks the lateral light emission of the first light emitting device 10, and the first light guide structure 031 increases the amount of light emitted by the first light emitting device 10 to the normal direction, thereby increasing the brightness of the first light emitting device 10 and reducing the power consumption of the display panel in the peep-proof mode.

[0053] As shown in FIG. 4, the thickness of the first refractive part 41 gradually increases in a direction from the center of the first light emitting device 10 to the edge, and the refractive index of the first refractive part 41 is smaller than that of the second refractive part 42. FIG. 4 shows the light path of the large-angle light emitted by the first light emitting device 10 being reflected on the interface between the first refractive part 41 and the second refractive part 42. The large-angle light emitted by the first light emitting device 10 is emitted from the second refractive part 42 to the first refractive part 41 in the first hollow V1 of the first refractive part 41, i.e., from the optically dense medium to the optically sparse medium, the reflected light is deflected to the normal direction, and total reflection can occur when the incident angle is greater than or equal to the critical angle. Therefore, the large-angle light emitted by the first light emitting device 10 is converged to the normal direction, thereby increasing the amount of light emitted by the first light emitting device 10 to the normal direction. The first light emitting device 10 is applied as a peep-proof pixel, the light blocking structure 02 blocks the lateral light emission of the first light emitting device 10, and increasing the amount of light emitted by the first light emitting device 10 to the normal direction increases the brightness of the first light emitting device 10, thereby reducing the power consumption of the display panel in the peep-proof mode.

[0054] In some embodiments, as shown in FIG. 4, the side wall of the first hollowed-out portion V1 of the first refractive portion 41 is curved. In other embodiments, as shown in FIG. 5, the thickness of the first refractive portion 41 gradually increases from the center of the first light-emitting device 10 to the edge. In a cross-sectional view, the side wall of the first hollowed-out portion V1 of the first refractive portion 41 is inclined.

[0055] As shown in FIG. 4, the first refractive portion 41 has a first side surface M1 and a first bottom surface M2. The distance between the first side surface M1 and the first bottom surface M2 gradually increases from the center of the first light-emitting device 10 to the edge. The included angle between the first side surface M1 and the first bottom surface M2 is θ1, and 30°≤θ1≤70°. When the first side surface M1 is curved, the included angle θ1 is defined by the tangent of the first side surface M1 and the first bottom surface M2. When the first side surface M1 is inclined as shown in FIG. 5, the included angle θ1 is defined by the slope angle of the first side surface M1 and the first bottom surface M2. In the embodiments of the present application, the wide-angle light emitted by the first light-emitting device 10 is reflected at the interface between the first refractive portion 41 and the second refractive portion 42 to deflect the light toward the normal direction, thereby increasing the amount of light emitted by the first light-emitting device 10 toward the normal direction. The setting of 30°≤θ1≤70° allows a larger proportion of the wide-angle light to be deflected toward the normal direction, that is, a larger proportion of the wide-angle light emitted by the first light-emitting device 10 can be deflected toward the normal direction after the action of the first light guide structure 031, thereby better increasing the brightness of the first light-emitting device 10.

[0056] In some embodiments, as shown in FIG. 4, along the first direction a, the width of the first opening K1 is D11, and the width of the first hollowed-out portion V1 is D12. The light-blocking structure 02 has a third opening K3, which at least partially overlaps the first light-emitting device 10 along the direction e perpendicular to the plane of the substrate 00. Along the first direction a, the width of the third opening K3 is D13. Wherein, D13≥D12>D11. Since the thickness of the first refractive portion 41 gradually increases from the center of the first light-emitting device 10 to the edge, the width of the first hollowed-out portion V1 gradually changes along the direction perpendicular to the plane of the substrate 00, and the width D12 of the first hollowed-out portion V1 is calculated based on the width of the side close to the substrate 00.

[0057] For the three parameters related to the first light emitting device 10, the width D11 of the first opening K1, the width D12 of the first hollow V1, and the width D13 of the third opening K3, the width D11 of the first opening K1 is set to be the smallest, which is beneficial to the rational use of the space for setting the light emitting device on the whole display panel, ensures the pixel density in the unit area of the display panel, and the size of the first light emitting device 10 can be set to be smaller than the size of the second light emitting device 20. D12>D11 is set, which can make full use of the large-angle light emitted by the first light emitting device 10 by the first light guide structure 031, so that the brightness of the first light emitting device 10 is improved more, and the effect of reducing power consumption is better. D13≥D12 is set, which can ensure that the light is blocked by the light blocking structure 03 after the action of the first light guide structure 031, so as to meet the application of the first light emitting device 10 as a privacy pixel.

[0058] In other embodiments, FIG. 6 is another schematic diagram of a display panel provided by the present application, which shows the cross-sectional view of the position of the first light emitting device 10. As shown in FIG. 6, along the first direction a, the width of the first opening K1 is D11, the width of the first hollow V1 is D12, and the width of the third opening K3 of the light blocking structure 02 is D13. Among them, D11>D12≥D13.

D11>D12 is set, so that the light above the first light guide structure 031 of the first light emitting device 10 can act more, and finally the brightness of the first light emitting device 10 is improved more, and the effect of reducing power consumption is better. D12≥D13 is set, which blocks the lateral light by the light blocking structure 02 above the first light guide structure 031, increases the forward light of the first light emitting device 10, and meets the application requirement of the first light emitting device 10 as a privacy pixel. In addition, the width D11 of the first opening K1 is set to be the largest, and in some embodiments, the corresponding opening sizes of the first light emitting device 10 and the second light emitting device 20 can be set to be the same, and the two do not need to be set differently, which reduces the process difficulty.

The light guide structure 03 comprises a second light guide structure 032, and the second light emitting device 20 at least partially overlaps the second light guide structure 032 along a direction e perpendicular to a plane where the substrate 00 is located. The second light guide structure 032 comprises a third refractive part 43 and a fourth refractive part 44 having different refractive indexes, and the third refractive part 43 is located on a side of the fourth refractive part 44 close to the substrate 00; and the third refractive part 43 at least partially overlaps the second light emitting device 20 along the direction e perpendicular to the plane where the substrate 00 is located. In this embodiment, the third refractive part 43 and the fourth refractive part 44 having different refractive indexes are stacked to form the second light guide structure 032, and the interface between the third refractive part 43 and the fourth refractive part 44 has a refractive effect on light, so that the light emitted by the second light emitting device 20 is deflected to a large-angle direction after the action of the second light guide structure 032, and the light is diffused, thereby increasing the amount of light emitted to the side by the second light emitting device 20. The second light emitting device 20 is applied as a shared pixel, and by adjusting the distance between the light blocking structure 02 and the second opening K2, the side light emission of the second light emitting device 20 can be ensured not to be blocked, and by increasing the amount of light emitted to the side by the second light emitting device 20 through the second light guide structure 032, the brightness when viewed at a large viewing angle can be improved, thereby reducing power consumption. In addition, in some embodiments, in the shared mode, the first light emitting device 10 and the second light emitting device 20 are both set to emit light, the first light guide structure 031 increases the amount of light emitted forward by the first light emitting device 10, and the second light guide structure 032 increases the amount of light emitted to the side by the second light emitting device 20, thereby balancing the brightness difference between the normal direction and the large-angle direction in the shared mode, and improving the overall display effect.

FIG. 7 schematically shows the light path of the light emitted by the second light emitting device 20 being refracted at the interface between the third refractive part 43 and the fourth refractive part 44. The light emitted by the second light emitting device 20 is emitted from the third refractive part 43 to the fourth refractive part 44, i.e., from a less dense medium to a denser medium, and the refractive angle is greater than the incident angle, so that the light is deflected to the side, or in other words, to a large-angle direction, thereby increasing the amount of light emitted at a large angle by the second light emitting device 20. The second light emitting device 20 is applied as a shared pixel, and increasing the amount of light emitted to the side by the second light emitting device 20 increases the brightness of the second light emitting device 20 at a large angle, which can reduce power consumption in the shared mode and improve the display effect when viewed at a large viewing angle.

The setting of 30°≤θ2≤70° enables a larger proportion of the light to be deflected to a large viewing angle, thereby better increasing the brightness of the second light emitting device 20 at a large viewing angle.

[0063] As shown in Fig. 7, along the first direction a, the width of the second opening K2 is D21, and the width of the third refractive part 43 is D22. The light-blocking structure 02 has a fourth opening K4, which at least partially overlaps with the second light emitting device 20 along the direction e perpendicular to the plane of the substrate 00. Along the first direction a, the width of the fourth opening K4 is D23. D23>D22≥D21. The first direction a is parallel to the plane of the substrate 00. For the three parameters related to the second light emitting device 20, the width D21 of the second opening K2, the width D22 of the third refractive part 43, and the width D23 of the fourth opening K4, the width D23 of the fourth opening K4 is set to be the largest, and the distance between the light-blocking structure 02 and the second opening K2 is adjusted to control the light emitting angle of the second light emitting device 20 to ensure the influence of the second light emitting device 20 as a shared pixel. The setting of D22≥D21 enables the light emitted by the second light emitting device 20 to be fully utilized, so that the amount of light diffused to a large angle by the second light emitting device 20 is larger, and the effect of improving the brightness of the second light emitting device 20 at a large viewing angle is better.

As shown in FIG. 9, the first light emitting device 10 includes a first color first light emitting device 11, and the second light emitting device 20 includes a first color second light emitting device 21. The first color first light emitting device 11 and the first color second light emitting device 21 have the same color. In a direction e perpendicular to the plane of the substrate 00, the first color first light emitting device 11 overlaps the first light guide structure 031, and the first color second light emitting device 21 overlaps the second light guide structure 032. The first hollow V1 overlapping the first color first light emitting device 11 in the direction e perpendicular to the plane of the substrate 00 has a width D15 in the first direction a, and the third refractive part 43 overlapping the first color second light emitting device 21 in the direction e perpendicular to the plane of the substrate 00 has a width D25 in the first direction a.

According to the sizes of the two light emitting devices and the functions of the two light guide structures 03, the structure sizes in the light guide structure 03 are designed, and D25>D15 is set, so that the first light guide structure 031 above the first color first light emitting device 11 has the function of converging light rays, and the second light guide structure 032 above the first color second light emitting device 21 has the function of diffusing light rays.

[0065] In other embodiments, FIG. 10 is a schematic diagram of another display panel provided by an embodiment of the present application. FIG. 10 schematically shows the position of the first light emitting device 10. As shown in FIG. 10, the light guide structure 03 includes a first light guide structure 031. In a direction e perpendicular to the plane of the substrate 00, the first light emitting device 10 at least partially overlaps the first light guide structure 031. The first light guide structure 031 includes a first refractive part 41 and a second refractive part 42 having different refractive indexes. The first refractive part 41 is located on the side of the second refractive part 42 close to the substrate 00. In the direction e perpendicular to the plane of the substrate 00, the first refractive part 41 at least partially overlaps the first light emitting device 10. In this embodiment, the first refractive part 41 and the second refractive part 42 having different refractive indexes are stacked to form the first light guide structure 031. The interface between the first refractive part 41 and the second refractive part 42 has a refractive effect on light rays, so that the large-angle light rays emitted by the first light emitting device 10 after being affected by the first light guide structure 031 can be deflected to the normal direction, so that the light rays converge, thereby increasing the amount of light emitted by the first light emitting device 10 to the normal direction. The first light emitting device 10 is applied as a privacy pixel. The light blocking structure 02 blocks the lateral light emission of the first light emitting device 10, and the first light guide structure 031 increases the amount of light emitted by the first light emitting device 10 to the normal direction, thereby increasing the brightness of the first light emitting device 10 and reducing the power consumption of the display panel in the privacy mode.

[0066] As shown in FIG. 10, the thickness of the first refractive part 41 gradually decreases from the center of the first light emitting device 10 to the edge; the refractive index of the first refractive part 41 is greater than the refractive index of the second refractive part 42. FIG. 10 schematically shows the light path of the large-angle light emitted by the first light emitting device 10 and refracted on the interface between the first refractive part 41 and the second refractive part 42. The large-angle light emitted by the first light emitting device 10 is emitted from the first refractive part 41 to the second refractive part 42, i.e. from the optically dense medium to the optically sparse medium, and the refractive angle is greater than the incident angle, so that the refracted light is deflected to the normal direction. Thus, it is equivalent to converging the large-angle light emitted by the first light emitting device 10 to the normal direction, thereby increasing the light output of the first light emitting device 10 to the normal direction. The first light emitting device 10 is applied as a peep-proof pixel, and the light blocking structure 02 blocks the lateral light output of the first light emitting device 10. Increasing the light output of the first light emitting device 10 to the normal direction increases the brightness of the first light emitting device 10, thereby reducing the power consumption of the display panel in the peep-proof mode.

When the third side surface M5 is a curved surface, the included angle θ3 is defined by the tangent of the third side surface M5 and the third bottom surface M6. When the third side surface M5 is an inclined surface, the included angle θ3 is defined by the slope angle formed by the third side surface M5 and the third bottom surface M6. In the embodiment of the present application, the large-angle light emitted by the first light emitting device 10 is refracted on the interface between the first refractive part 41 and the second refractive part 42 to deflect the light to the normal direction, thereby increasing the light output of the first light emitting device 10 to the normal direction. The 30°≤θ3≤70° is set to make the proportion of the large-angle light deflected to the normal direction larger, i.e. most of the large-angle light emitted by the first light emitting device 10 can be deflected to the normal direction after the action of the first light guide structure 031, thereby better increasing the brightness of the first light emitting device 10.

[0069] As shown in FIG. 10, along the first direction a, the width of the first opening K1 is D11, and the width of the first refractive portion 41 is D14; the light-blocking structure 02 has a third opening K3, the third opening K3 at least partially overlaps the first light-emitting device 10 along the direction e perpendicular to the plane in which the substrate 00 lies; along the first direction a, the width of the third opening K3 is D13; wherein D13≥D14>D11. For the three parameters related to the first light-emitting device 10, the width D11 of the first opening K1, the width D14 of the first refractive portion 41, and the width D13 of the third opening K3, the width D11 of the first opening K1 is set to be the smallest, which is beneficial to reasonably utilize the space for arranging the light-emitting device on the whole display panel, and ensures the pixel density per unit area of the display panel, for example, the size of the first light-emitting device 10 can be set to be smaller than the size of the second light-emitting device 20. D14>D11 is set, which can make full use of the large-angle light emitted by the first light-emitting device 10 by the first light guide structure 031, so that the first light-emitting device 10 has more improved brightness and better power consumption reduction effect. D13≥D14 is set, which can ensure that the light is blocked by the light-blocking structure 03 after the action of the first light guide structure 031, so as to meet the application of the first light-emitting device 10 as a privacy pixel.

The second light emitting device 20 is applied as a shared pixel, by adjusting the distance between the light blocking structure 02 and the second opening K2, the side light emission of the second light emitting device 20 can be ensured not to be blocked, the amount of light emitted to the side by the second light emitting device 20 is increased by the second light guide structure 032, which can improve the brightness when viewed at a large viewing angle and thereby reduce power consumption. In addition, in some embodiments, both the first light emitting device 10 and the second light emitting device 20 are set to emit light in the shared mode, the first light guide structure 031 increases the amount of light emitted forward by the first light emitting device 10, and the second light guide structure 032 increases the amount of light emitted to the side by the second light emitting device 20, thereby balancing the brightness difference between the normal direction and the large-angle direction in the shared mode and improving the overall display effect.

FIG. 12 illustrates the light path of the light emitted by the second light emitting device 20 being refracted at the interface between the third refractive part 43 and the fourth refractive part 44. The light emitted by the second light emitting device 20 is emitted from the third refractive part 43 to the fourth refractive part 44, i.e. from a light-dense medium to a light-sparse medium, the refraction angle is smaller than the incidence angle, so that the light is deflected to the side, thereby increasing the amount of light emitted at a large viewing angle by the second light emitting device 20. The second light emitting device 20 is applied as a shared pixel, increasing the amount of light emitted to the side increases the brightness of the second light emitting device 20 at a large viewing angle, which can reduce power consumption in the shared mode and improve the display effect when viewed at a large viewing angle.

In other embodiments, the fourth side surface M7 is an inclined surface, and the included angle θ4 is defined by the slope angle formed by the fourth side surface M7 and the fourth bottom surface M8. In the embodiments of the present application, the wide-angle light emitted by the second light emitting device 20 is refracted at the interface between the third refractive part 43 and the fourth refractive part 44 to deflect the light towards the large viewing angle direction, thereby increasing the amount of light emitted by the second light emitting device 20 towards the large viewing angle direction. The setting of 30°≤θ2≤70° enables a larger proportion of the light to be deflected towards the large viewing angle, thereby better increasing the brightness of the second light emitting device 20 at the large viewing angle.
