Description

Technical Field

[0001] The present invention relates to the field of display technology, and in particular to a display panel and a display device. Background Art

[0002] Users have privacy needs when using display products in public places. Although privacy films meet users' privacy needs, only users facing the screen can see the content on the screen after applying the privacy films, which also limits the use environment of display products after applying the films. Therefore, the research on active privacy protection solutions is also known as one of the technical problems that current display products need to overcome. However, the current active privacy protection solutions will increase the power consumption of displays. Summary of the invention

[0003] Embodiments of the present invention provide a display panel and a display device to solve the technical problem of reducing display power consumption in an active anti-peeping solution.

[0004] In a first aspect, an embodiment of the present invention provides a display panel, including:

[0005] A substrate and a display layer located on one side of the substrate, the display layer including a pixel definition layer and a plurality of light emitting devices, the pixel definition layer including a first opening and a second opening, the light emitting devices including 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;

[0006] A light-blocking structure is located on a side of the display layer away from the substrate; an orthographic projection of at least part of the light-blocking structure on the substrate is located between orthographic projections of two adjacent light-emitting devices on the substrate; along a first direction, a distance between the light-blocking structure and the first opening is less than a distance between the light-blocking structure and the second opening, and the first direction is parallel to a plane where the substrate is located;

[0007] The light guide structure is located on a side of the display layer away from the substrate; along a 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.

[0008] In a second aspect, based on the same inventive concept, an embodiment of the present invention provides a display device, including the display panel provided by any embodiment of the present invention.

[0009] The display panel and display device provided by the embodiment of the present invention have the following beneficial effects: in the embodiment of the present invention, 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 an anti-peeping pixel, and the second light-emitting device can be used as a shared pixel. When the first light-emitting device is turned on, active anti-peeping is realized. A light-guiding 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 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. The light-guiding effect of the light-guiding structure can reduce the power consumption of the display panel. For example, a light-guiding structure overlapping with the first light-emitting device is arranged to converge the light and emit more large-angle light from the front view direction, thereby increasing the brightness of the first light-emitting device and reducing the power consumption of the display panel in the anti-peeping mode; a light-guiding structure overlapping with the second light-emitting device is arranged to diffuse the light so that more light is emitted at a large angle, thereby increasing the brightness when the user watches at a large viewing angle and reducing the power consumption of the display panel in the shared mode.

[0033] In order to make the purpose, technical solution and advantages of the embodiments of the present invention clearer, the technical solution in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0034] The terms used in the embodiments of the present invention are only for the purpose of describing specific embodiments, and are not intended to limit the present invention. The singular forms "a", "said" and "the" used in the embodiments of the present invention and the appended claims are also intended to include plural forms, unless the context clearly indicates other meanings.

[0035] An embodiment of the present invention provides an active anti-peeping display panel, in which a first light-emitting device and a second light-emitting device with different light-emitting angles are arranged, the first light-emitting device serves as an anti-peeping pixel, and the second light-emitting device serves as a shared pixel, so that the display panel can be switched between an anti-peeping mode and a shared mode, thereby realizing an active anti-peeping solution. A light-guiding structure is arranged on the first light-emitting device and / or the second light-emitting device, and the light-guiding effect of the light-guiding structure is utilized to reduce the power consumption of the display panel.

[0036] Figure 1 A schematic diagram of a display panel provided by an embodiment of the present invention, Figure 2 for Figure 1 A schematic diagram of a cross section at the midline AA′. Figure 1 As shown, the light-emitting device 1 in the display panel includes a first light-emitting device 10 and a second light-emitting device 20. The first light-emitting device 10 includes a first light-emitting device 11 of a first color, a first light-emitting device 12 of a second color, and a first light-emitting device 13 of a third color. The second light-emitting device 20 includes a first light-emitting device 21 of a first color, a second light-emitting device 22 of a second color, and a second light-emitting device 23 of a third color. The first light-emitting device 11 of the first color, the first light-emitting device 12 of the second color, and the first light-emitting device 13 of the third color are respectively one of a red light-emitting device, a green light-emitting device, and a blue light-emitting device. 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, and the third color second light-emitting device 23 has the same color as the third color first light-emitting device 13. Figure 1 The shape and arrangement of the light emitting device 1 are only schematically shown and are not intended to limit the present invention. In the embodiment of the present invention, the shape of the light emitting device 1 can be circular, rectangular or other polygonal, or irregular.

[0037] Combination Figure 2As shown, the display panel includes a substrate 00, a display layer 01 is located on one side of the substrate 00, and a light-blocking structure 02 and a light-guiding structure 03 are located on the 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 within the first opening K1, and a second light-emitting device 20 is located within 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 a packaging layer 05. A pixel circuit is provided in the driving layer 04, and the pixel circuit is electrically connected to the first electrode 1a and is used to drive the light-emitting device 1 to emit light. The packaging layer 05 is located on the side of the display layer 01 away from the substrate 00, and the packaging layer 05 is used to isolate water and oxygen and protect the light-emitting device 1. Optionally, the packaging layer 05 includes at least one organic packaging layer and at least one inorganic packaging layer.

[0038] At least a part of the orthographic projection of the light-blocking structure 02 on the substrate 00 is located between the orthographic projections of two adjacent light-emitting devices 1 on the substrate 00. The display panel further includes a light-filtering unit 06. Along the direction e perpendicular to the plane where the substrate 00 is located, the light-filtering unit 06 overlaps with the light-emitting device 1. The light-blocking structure 02 is used to block light from entering the interior of the display panel, and 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 play a role in reducing the reflectivity of the display panel. 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, where d1 < d2, and the first direction a is parallel to the plane where the substrate 00 is located. 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 of the present invention, 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 applications, 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, it is possible to make the light emitted by the first light-emitting device 10 basically emit in the front view direction of the display panel (that is, the direction e perpendicular to the plane where the substrate 00 is located). When the first light-emitting device 10 is lit, the user cannot view the light emission of the first light-emitting device 10 in the large viewing angle direction, thereby achieving the privacy protection effect.

[0039] From Figure 2It can be seen that 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-guiding structure 03, and the second light-emitting device 20 at least partially overlaps with the light-guiding structure 03. Among them, the light-guiding structure 03 overlapping with the first light-emitting device 10 is used to converge the light, and more large-angle light is emitted from the front view direction, thereby increasing the brightness of the first light-emitting device 10 and reducing power consumption. The light-guiding structure 03 overlapping with the second light-emitting device 20 is used to diffuse the light, so that more light is emitted at a large angle, and the brightness is increased when viewed from a large viewing angle, thereby reducing power consumption.

[0040] Figure 2 As shown in FIG. 1 , the first light emitting device 10 and the second light emitting device 20 overlap at least partially with the light guide structure 03 . In other embodiments, Figure 3 for Figure 1 Another cross-sectional diagram at the midline AA′. Figure 3 In the figure, 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-guiding structure 03. The light-guiding structure 03 is not arranged on the second light-emitting device 20. In other embodiments, 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-guiding structure 03. The light-guiding structure 03 is not arranged on the first light-emitting device 10, and is not illustrated in the figure.

[0041] In the embodiment of the present invention, the distance between the light-blocking structure 02 and the opening of the pixel definition layer 011 is set 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 the application, the first light-emitting device 10 can be used as an anti-peeping pixel, and the second light-emitting device 20 can be used as a shared pixel. When the first light-emitting device 10 is turned on, active anti-peeping is achieved. A light-guiding structure 03 is provided on the side of the display layer 01 away from the substrate 00. In 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-guiding structure 03, and / or the second light-emitting device 20 at least partially overlaps with the light-guiding structure 03. The light-guiding effect of the light-guiding structure 03 can reduce the power consumption of the display panel. For example, the light-guiding structure 03 overlapping with the first light-emitting device 10 converges the light and emits more large-angle light from the straight-view direction, thereby increasing the brightness of the first light-emitting device 10 and reducing the power consumption of the display panel in the anti-peep mode; the light-guiding structure 03 overlapping with the second light-emitting device 20 diffuses the light and emits more light at a large angle, thereby increasing the brightness when the user watches at a large viewing angle and reducing the power consumption of the display panel in the sharing mode.

[0042] In some embodiments, the display panel includes 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 an anti-peeping mode, and the second display mode is a sharing mode. In the anti-peeping mode, only the first light-emitting device 10 emits light, which avoids lateral light leakage and ensures the anti-peeping 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 requirements in the sharing mode and reduce power consumption. Since the first light-emitting device 10 mainly emits light in the front view direction, the lateral light output of the second light-emitting device 20 can be increased by setting the light-guiding structure 03, thereby balancing the brightness difference between the front view direction and the wide viewing angle direction in the sharing mode and improving the overall display effect.

[0043] In some embodiments, Figure 2 As shown, 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, 2μm≤d2-d1≤5μm. In the embodiment of the present invention, the difference between d2 and d1 is set to meet a certain range, which can balance the requirements for setting the difference in the light emitting angles of the first light emitting device 10 and the second light emitting device 20 and the display panel manufacturing process capabilities, and produce the second light emitting device 20 with a larger light emitting angle and the first light emitting device 10 with a relatively smaller light emitting angle within the effective area space of the display panel, thereby realizing an active anti-peeping solution.

[0044] In some embodiments, 1 μm≤d1≤2 μm, and 4 μm≤d2≤6 μm.

[0045] like Figure 2 As shown, the light-blocking structure 02 is located on the side of the light-guiding structure 03 away from the light-emitting device 1. In the embodiment of the present invention, the light-shielding effect of the light-blocking structure 02 is utilized, and the distance between the light-blocking structure 02 and the opening of the pixel definition layer 011 is set 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. When the first light-emitting device 10 is lit, the anti-peeping effect can be achieved. The light-guiding structure 03 is disposed between the light-emitting device 1 and the film layer where the light-blocking structure 02 is located, and the light-guiding effect of the light-guiding structure 03 is utilized to reduce the power consumption of the display panel.

[0046] For the first light-emitting device 10, the light emitted by it is firstly converged by using the light-guiding structure 03, so that more light is emitted from the normal viewing direction, and then the light-blocking structure 02 is used to block the light emitted from a large viewing angle, thereby achieving an anti-peeping 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-guiding structure 03 away from the light-emitting device 1, which can meet the application requirements of the first light-emitting device 10 as an anti-peeping pixel.

[0047] For the second light-emitting device 20, the light is diffused by using the light-guiding structure 03 so that more light is emitted at a larger angle. At the same time, the distance between the light-blocking structure 02 and the second opening K2 is set relatively large, so that the light-blocking structure 02 will not affect the light emission at a large viewing angle, so that the brightness of the second light-emitting device 20 is increased when viewed at a large viewing angle, thereby reducing power consumption. The light-blocking structure 02 is set on the side of the light-guiding structure 03 away from the light-emitting device 1, and the distance between the light-blocking structure 02 and the second opening K2 is designed 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-guiding structures 03, the space of the film layer where the light-guiding structure 03 is located can be reasonably utilized, so that power consumption can be reduced in both anti-peeping mode and sharing mode.

[0048] In some embodiments, Figure 2 As shown, the light guide structure 03 includes a first light guide structure 031 and a second light guide structure 032; along a direction e perpendicular to the plane where the substrate 00 is located, the first light-emitting device 10 at least partially overlaps with the first light guide structure 031, and the second light-emitting device 20 at least partially overlaps with the second light guide structure 032; the first light guide structure 031 includes a first refraction portion 41 and a second refraction portion 43 with different refractive indices, and the first refraction portion 41 is located on a side of the second refraction portion 42 close to the substrate 00; the second light guide structure 032 includes a third refraction portion 43 and a fourth refraction portion 44 with different refractive indices, and the third refraction portion 43 is located on a side of the fourth refraction portion 44 close to the substrate 00; wherein the first refraction portion 41 and the third refraction portion 43 are made of the same material, and the second refraction portion 42 and the fourth refraction portion 44 are made of the same material. In this embodiment, the first refraction part 41 and the third refraction part 43 can be manufactured in the same process, and the second refraction part 42 and the fourth refraction 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 the power consumption be reduced in both the anti-peeping mode and the sharing mode, but the process is also simple.

[0049] Figure 2In the embodiment, the refractive index of the first refractive portion 41 is smaller than the refractive index of the second refractive portion 42, and the refractive index of the third refractive portion 43 is smaller than the refractive index of the fourth refractive portion 44. In other embodiments, the refractive index of the first refractive portion 41 is greater than the refractive index of the second refractive portion 42, and the refractive index of the third refractive portion 43 is greater than the refractive index of the fourth refractive portion 44, which will be schematically described in the subsequent drawings of related embodiments.

[0050] In some embodiments, Figure 4 A schematic cross-sectional view of another display panel provided by an embodiment of the present invention, Figure 4 Only the cross-sectional view of the area where the first light emitting device 10 is located is shown. Figure 4 As shown, the light guide structure 03 includes a first light guide structure 031; 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 first light guide structure 031. The first light guide structure 031 includes a first refractive portion 41 and a second refractive portion 42 with different refractive indices, and the first refractive portion 41 is located on the side of the second refractive portion 42 close to the substrate 00. The first refractive portion 41 has a first hollow V1, and at least part of the second refractive portion 42 is located in the first hollow V1; along the direction perpendicular to the plane where the substrate 00 is located, the first hollow V1 at least partially overlaps with the first light emitting device 10. In this embodiment, the first refractive portion 41 and the second refractive portion 42 with different refractive indices are stacked to form the first light guide structure 031, and the interface between the first refractive portion 41 and the second refractive portion 42 has a reflective effect on the light, so that the large-angle light emitted by the first light emitting device 10 after the first light guide structure 031 acts can be deflected in the normal viewing direction, so that the light converges, thereby increasing the amount of light emitted by the first light emitting device 10 in the normal viewing direction. The first light-emitting device 10 is used as an anti-peeping pixel. The light-blocking structure 02 is used to block the lateral light emitted by the first light-emitting device 10. At the same time, the first light-guiding structure 031 is used to increase the amount of light emitted by the first light-emitting device 10 in the front direction, thereby increasing the brightness of the first light-emitting device 10 and reducing the power consumption of the display panel in the anti-peeping mode.

[0051] like Figure 4 As shown, in the direction from the center to the edge of the first light emitting device 10 , the thickness of the first refractive portion 41 gradually increases; the refractive index of the first refractive portion 41 is smaller than the refractive index of the second refractive portion 42 . Figure 4The optical path of the large-angle light emitted by the first light-emitting device 10 reflected at the interface of the first refractive portion 41 and the second refractive portion 42 is illustrated. The large-angle light emitted by the first light-emitting device 10 is emitted from the second refractive portion 42 to the first refractive portion 41 in the first hollow V1 of the first refractive portion 41, that is, from the light-dense medium to the light-sparse medium, and the reflected light is deflected in the front-view direction, and total reflection can occur when the incident angle is greater than or equal to the critical angle. This is equivalent to converging the large-angle light emitted by the first light-emitting device 10 in the front-view direction, increasing the amount of light emitted by the first light-emitting device 10 in the front-view direction. The first light-emitting device 10 is used as an anti-peeping pixel, and the light-blocking structure 02 is used to block the lateral light emission of the first light-emitting device 10, while increasing the light emission of the first light-emitting device 10 in the front-view direction, thereby increasing the brightness of the first light-emitting device 10, which can reduce the power consumption of the display panel in the anti-peeping mode.

[0052] Figure 4 The side wall of the first hollow V1 of the first refractive portion 41 in the schematic cross-sectional view is a curved surface. Figure 5 A schematic diagram of another display panel provided by an embodiment of the present invention, such as Figure 5 As shown, the thickness of the first refraction portion 41 gradually increases in the direction from the center to the edge of the first light emitting device 10 ; in the cross-sectional view, the side wall of the first hollow V1 of the first refraction portion 41 is an inclined surface.

[0053] like Figure 4 As shown, the first refractive portion 41 has a first side surface M1 and a first bottom surface M2; in the direction from the center of the first light-emitting device 10 to the edge, the distance between the first side surface M1 and the first bottom surface M2 gradually increases. The angle formed by the first side surface M1 and the first bottom surface M2 toward the first refractive portion 41 is θ1, 30°≤θ1≤70°. When the first side surface M1 is a curved surface, the angle θ1 is defined by the angle formed by the tangent of the first side surface M1 and the first bottom surface M2. When the first side surface M1 is Figure 5 When the inclined plane is shown, the angle θ1 is defined by the slope angle formed by the first side surface M1 and the first bottom surface M2. In the embodiment of the present invention, the large-angle light emitted by the first light-emitting device 10 is reflected at the interface between the first refraction portion 41 and the second refraction portion 42 to deflect the light in the normal viewing direction, thereby increasing the amount of light emitted by the first light-emitting device 10 in the normal viewing direction. It is set that 30°≤θ1≤70°, so that the large-angle light that can be deflected in the normal viewing direction accounts for a larger proportion, that is, most of the large-angle light emitted by the first light-emitting device 10 can be deflected in the normal viewing direction after being acted on by the first light-guiding structure 031, thereby having a better effect on increasing the brightness of the first light-emitting device 10.

[0054] In some embodiments, Figure 4As shown, along the first direction a, the width of the first opening K1 is D11, and the width of the first hollow V1 is D12; the light blocking structure 02 has a third opening K3, and along the direction e perpendicular to the plane where the substrate 00 is located, the third opening K3 at least partially overlaps with the first light-emitting device 10; 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 in the direction from the center to the edge of the first light-emitting device 10, the width of the first hollow V1 along the first direction a gradually changes in the direction perpendicular to the plane where the substrate 00 is located, and the width D12 of the first hollow V1 is calculated based on the width of the side close to the substrate 00.

[0055] For the three parameters related to the first light-emitting device 10, namely, 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, setting the width D11 of the first opening K1 to be the smallest is conducive to the rational use of the space for setting the light-emitting devices on the entire surface of the display panel, and ensuring the pixel density per unit area of ​​the display panel. For example, the size of the first light-emitting device 10 can be set smaller than the size of the second light-emitting device 20. By setting D12>D11, the first light-guiding structure 031 can be used to fully utilize the large-angle light emitted by the first light-emitting device 10, so that the brightness of the first light-emitting device 10 is further improved and the power consumption is reduced better. By setting D13≥D12, it can be ensured that after the light passes through the first light-guiding structure 031, the light blocking structure 03 is used to block the lateral light of the first light-emitting device 10, so that the first light-emitting device 10 can be used as an anti-peeping pixel.

[0056] In other embodiments, Figure 6 Another display panel schematic diagram provided for the implementation of the present invention, Figure 6 FIG. 1 is a cross-sectional view showing the location of the first light emitting device 10. Figure 6As shown, 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. For the three parameters related to the first light-emitting device 10, namely, 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, if the width D11 of the first opening K1 is set to be the largest, the overall light output of the first light-emitting device 10 is larger, and the large-angle light output is also more. Then, setting D11>D12 allows the first light-guiding structure 031 on the first light-emitting device 10 to act on more light, and ultimately makes the brightness of the first light-emitting device 10 more improved and the power consumption reduction effect better. Setting D12≥D13, the light-blocking structure 02 on the first light-guiding structure 031 is used to block the lateral light output, thereby increasing the forward light output of the first light-emitting device 10 while meeting its application requirements as an anti-peeping pixel. In addition, the width D11 of the first opening K1 is set to be the largest. In some embodiments, the first light-emitting device 10 and the second light-emitting device 20 may have the same corresponding opening size and do not need to be set differently, thereby reducing the difficulty of the process.

[0057] In some embodiments, Figure 7 A schematic diagram of another display panel provided by an embodiment of the present invention, Figure 7The cross-sectional view of the position of the second light-emitting device 20 is illustrated. The light-guiding structure 03 includes a second light-guiding structure 032. In 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 second light-guiding structure 032. The second light-guiding structure 032 includes a third refractive portion 43 and a fourth refractive portion 44 with different refractive indices. The third refractive portion 43 is located on the side of the fourth refractive portion 44 close to the substrate 00; in the direction e perpendicular to the plane where the substrate 00 is located, the third refractive portion 43 at least partially overlaps with the second light-emitting device 20. In this embodiment, the third refractive portion 43 and the fourth refractive portion 44 with different refractive indices are stacked to form the second light-guiding structure 032. The interface between the third refractive portion 43 and the fourth refractive portion 44 has a refractive effect on the light, so that the light emitted by the second light-emitting device 20 after the second light-guiding structure 032 acts is deflected in a large angle direction, so that the light is diffused, thereby increasing the amount of light emitted laterally by the second light-emitting device 20. The second light-emitting device 20 is used as a shared pixel. By adjusting the distance between the light-blocking structure 02 and the second opening K2, it can be ensured that the lateral light output of the second light-emitting device 20 is not blocked. The second light-guiding structure 032 increases the amount of light emitted to the side by the second light-emitting device 20, which can improve the brightness when viewed from a wide viewing angle, thereby reducing power consumption. In addition, in some embodiments, the first light-emitting device 10 and the second light-emitting device 20 are both set to emit light in the shared mode, the first light-guiding structure 031 increases the amount of forward light output of the first light-emitting device 10, and the second light-guiding structure 032 increases the amount of lateral light output of the second light-emitting device 20, thereby balancing the brightness difference between the front view direction and the wide viewing angle direction in the shared mode and improving the overall display effect.

[0058] like Figure 7 As shown, in the direction from the center to the edge of the second light emitting device 20 , the thickness of the third refractive portion 43 gradually decreases; the refractive index of the third refractive portion 43 is less than the refractive index of the fourth refractive portion 44 . Figure 7 The optical path of the light emitted by the second light emitting device 20 refracted at the interface between the third refraction portion 43 and the fourth refraction portion 44 is illustrated. The light emitted by the second light emitting device 20 is emitted from the third refraction portion 43 to the fourth refraction portion 44, that is, from the optically sparse medium to the optically dense medium, and the refraction angle is greater than the incident angle, so that the light is deflected laterally, or in the direction of a wide viewing angle, thereby increasing the light output of the second light emitting device 20 at a wide viewing angle. The second light emitting device 20 is used as a shared pixel, and increasing its lateral light output increases the brightness of the second light emitting device 20 at a wide viewing angle, which can reduce power consumption in the shared mode and improve the display effect when viewed at a wide viewing angle.

[0059] Figure 7 The second side surface M3 of the edge portion of the third refractive portion 43 in the schematic cross-sectional view is a curved surface. Figure 8A schematic diagram of another display panel provided by an embodiment of the present invention, such as Figure 8 As shown, the thickness of the third refraction portion 43 gradually decreases in the direction from the center to the edge of the second light emitting device 20; in the cross-sectional view, the second side surface M3 of the edge of the third refraction portion 43 is a slope.

[0060] like Figure 7 As shown, the third refractive portion 43 has a second side surface M3 and a second bottom surface M4; in the direction from the center of the second light emitting device 20 to the edge, the distance between the second side surface M3 and the second bottom surface M4 gradually decreases; the angle formed by the second side surface M3 and the second bottom surface M4 toward the third refractive portion 43 is θ2, 30°≤θ2≤70°. When the second side surface M3 is a curved surface, the angle θ2 is defined by the angle formed by the tangent of the second side surface M3 and the second bottom surface M4. When the second side surface M3 is Figure 8 When the inclined plane is shown, the angle θ2 is defined by the slope angle formed by the second side surface M3 and the second bottom surface M4. In the embodiment of the present invention, the large-angle light emitted by the second light-emitting device 20 is refracted at the interface between the third refraction portion 43 and the fourth refraction portion 44 to deflect the light in the direction of the large viewing angle, thereby increasing the amount of light emitted by the second light-emitting device 20 in the direction of the large viewing angle. Setting 30°≤θ2≤70° allows a larger proportion of light that can be deflected in the direction of the large viewing angle, thereby having a better effect on increasing the brightness of the second light-emitting device 20 at a large viewing angle.

[0061] like Figure 7 As shown, along the first direction a, the width of the second opening K2 is D21, and the width of the third refractive portion 43 is D22; the light-blocking structure 02 has a fourth opening K4, and along the direction e perpendicular to the plane where the substrate 00 is located, the fourth opening K4 at least partially overlaps with the second light-emitting device 20; along the first direction a, the width of the fourth opening is D23; wherein D23>D22≥D21. The first direction a is parallel to the plane direction where the substrate 00 is located. For the three parameters related to the second light-emitting device 20, namely, the width D21 of the second opening K2, the width D22 of the third refractive portion 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 light-emitting angle of the second light-emitting device 20 is controlled by adjusting the distance between the light-blocking structure 02 and the second opening K2 to ensure the influence of the second light-emitting device 20 as a shared pixel. Setting D22≥D21 can fully utilize the light emitted by the second light emitting device 20, so that the second light emitting device 20 diffuses more light at a larger angle, which has a better effect on improving the brightness of the second light emitting device 20 at a larger viewing angle.

[0062] In some embodiments, Fig. 9 A schematic diagram of another display panel provided by an embodiment of the present invention, such as Fig. 9As shown, the first light-emitting device 10 includes a first light-emitting device 11 of a first color, and the second light-emitting device 20 includes a second light-emitting device 21 of a first color. The colors of the first light-emitting device 11 of the first color and the second light-emitting device 21 of the first color are the same: along the direction e perpendicular to the plane where the substrate 00 is located, the first light-emitting device 11 of the first color overlaps with the first light-guiding structure 031, and the second light-emitting device 21 of the first color overlaps with the second light-guiding structure 032. The width of the first hollow V1 overlapping with the first light-emitting device 11 of the first color along the direction e perpendicular to the plane where the substrate 00 is located in the first direction a is D15, and the width of the third refraction portion 43 overlapping with the first light-emitting device 21 of the first color along the direction e perpendicular to the plane where the substrate 00 is located in the first direction a is D25; D25>D15. The first light-guiding structure 031 and the second light-guiding structure 032 have different functions. The structural dimensions of the light-guiding structure 03 are designed according to the sizes of the two light-emitting devices and the functions of the two light-guiding structures 03, and D25>D15 is set, so that the first light-guiding structure 031 on the first light-emitting device 11 of the first color has the function of converging light, and the second light-guiding structure 032 on the first light-emitting device 21 of the first color has the function of diffusing light.

[0063] In other embodiments, Fig.10 A schematic diagram of another display panel provided by an embodiment of the present invention, Fig.10 The position of the first light emitting device 10 is shown in FIG. Fig.10 As shown, the light guide structure 03 includes a first light guide structure 031; 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 first light guide structure 031; the first light guide structure 031 includes a first refractive portion 41 and a second refractive portion 42 with different refractive indices, and the first refractive portion 41 is located on the side of the second refractive portion 42 close to the substrate 00; along the direction e perpendicular to the plane where the substrate 00 is located, the first refractive portion 41 at least partially overlaps with the first light emitting device 10. In this embodiment, the first refractive portion 41 and the second refractive portion 42 with different refractive indices are stacked to form the first light guide structure 031, and the interface between the first refractive portion 41 and the second refractive portion 42 has a refractive effect on the light, so that the large-angle light emitted by the first light emitting device 10 after the first light guide structure 031 acts can be deflected in the normal viewing direction, so that the light converges, thereby increasing the amount of light emitted by the first light emitting device 10 in the normal viewing direction. The first light-emitting device 10 is used as an anti-peeping pixel. The light-blocking structure 02 is used to block the lateral light emitted by the first light-emitting device 10. At the same time, the first light-guiding structure 031 is used to increase the amount of light emitted by the first light-emitting device 10 in the front direction, thereby increasing the brightness of the first light-emitting device 10 and reducing the power consumption of the display panel in the anti-peeping mode.

[0064] like Fig.10As shown, in the direction from the center to the edge of the first light emitting device 10 , the thickness of the first refractive portion 41 gradually decreases; the refractive index of the first refractive portion 41 is greater than the refractive index of the second refractive portion 42 . Fig.10 The diagram illustrates the optical path of the large-angle light emitted by the first light-emitting device 10 refracted at the interface of the first refraction portion 41 and the second refraction portion 42. The large-angle light emitted by the first light-emitting device 10 is incident from the first refraction portion 41 to the second refraction portion 42, that is, from the light-dense medium to the light-sparse medium, and the refraction angle is greater than the incident angle, so that the refracted light is deflected in the normal viewing direction. This is equivalent to converging the large-angle light emitted by the first light-emitting device 10 in the normal viewing direction, thereby increasing the amount of light emitted by the first light-emitting device 10 in the normal viewing direction. The first light-emitting device 10 is used as an anti-peeping pixel, and the light-blocking structure 02 is used to block the lateral light emission of the first light-emitting device 10, while increasing the light emission of the first light-emitting device 10 in the normal viewing direction, thereby increasing the brightness of the first light-emitting device 10, and can reduce the power consumption of the display panel in the anti-peeping mode.

[0065] Fig.10 In the schematic cross-sectional view of the embodiment, the side wall of the edge of the first refractive portion 41 is a curved surface. In other embodiments, the side wall of the edge of the first refractive portion 41 is an inclined surface. The shape of the first refractive portion 41 is similar to Figure 8 The shape of the third refractive portion 43 is shown in FIG.

[0066] like Fig.10 As shown, the third refractive portion 43 has a third side surface M5 and a third bottom surface M6; in the direction from the center of the first light-emitting device 10 to the edge, the distance between the third side surface M5 and the third bottom surface M6 gradually decreases; the angle formed by the third side surface M5 and the third bottom surface M6 toward the third refractive portion 43 is θ3, 30°≤θ3≤70°. When the third side surface M5 is a curved surface, the angle θ3 is defined by the angle formed 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 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 invention, the large-angle light emitted by the first light-emitting device 10 is refracted at the interface of the first refractive portion 41 and the second refractive portion 42 to deflect the light in the normal viewing direction, thereby increasing the amount of light emitted by the first light-emitting device 10 in the normal viewing direction. By setting 30°≤θ3≤70°, a larger proportion of large-angle light rays can be deflected in the normal viewing direction, that is, most of the large-angle light rays emitted by the first light-emitting device 10 can be deflected in the normal viewing direction after being acted upon by the first light-guiding structure 031, thereby having a better effect on increasing the brightness of the first light-emitting device 10.

[0067] like Fig.10As shown, 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, and along the direction e perpendicular to the plane where the substrate 00 is located, the third opening K3 at least partially overlaps with the first light-emitting device 10; 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, setting the width D11 of the first opening K1 to be the smallest is conducive to the reasonable use of the space for setting the light-emitting devices on the entire surface of the display panel, and ensuring the pixel density per unit area of ​​the display panel, such as 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. Setting D14>D11 can make full use of the large-angle light emitted by the first light-emitting device 10 by using the first light-guiding structure 031, so that the brightness of the first light-emitting device 10 is further improved and the power consumption is reduced better. Setting D13≥D14 can ensure that after the light passes through the first light guide structure 031 , the light blocking structure 03 is used to block the lateral light emitted by the first light emitting device 10 , so that the first light emitting device 10 can be used as an anti-peeping pixel.

[0068] In other embodiments, Fig.11 Another display panel schematic diagram provided for the implementation of the present invention, Fig.11 FIG. 1 is a cross-sectional view showing the location of the first light emitting device 10. Fig.11 As shown, 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 width of the third opening K3 in the light-blocking structure 02 is D13; wherein, D11>D14≥D13. If the width D11 of the first opening K1 is set to be the largest, the overall light output of the first light-emitting device 10 is larger, and the large-angle light output is also more. Then, D11>D14 is set so that the first light-guiding structure 031 on the first light-emitting device 10 can act on more light, and finally the brightness of the first light-emitting device 10 is improved more and the power consumption is reduced better. By setting D14≥D13, the light-blocking structure 02 on the first light-guiding structure 031 is used to block the lateral light output, so that the forward light output of the first light-emitting device 10 is increased while meeting its application requirements as an anti-peeping pixel. In addition, by setting the width D11 of the first opening K1 to be the largest, 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 there is no need to set them differently, thereby reducing the process difficulty.

[0069] In some embodiments, Fig.12 A schematic diagram of another display panel provided by an embodiment of the present invention, Fig.12 Schematic diagram of the cross-section at the location of the second light emitting device 20. Fig.12 As shown, the light guide structure 03 includes a second light guide structure 032, and 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 second light guide structure 032. The second light guide structure 032 includes a third refractive portion 43 and a fourth refractive portion 44 with different refractive indices, and the third refractive portion 43 is located on the side of the fourth refractive portion 44 close to the substrate 00; the third refractive portion 43 has a second hollow V2, and at least part of the fourth refractive portion 44 is located in the second hollow V2; along the direction e perpendicular to the plane where the substrate 00 is located, the second hollow V2 at least partially overlaps with the second light emitting device 20. In this embodiment, the third refractive portion 43 and the fourth refractive portion 44 with different refractive indices are stacked to form the second light guide structure 032, and the interface between the third refractive portion 43 and the fourth refractive portion 44 has a refractive effect on the light, so that the light emitted by the second light emitting device 20 after the second light guide structure 032 acts is deflected in a large angle direction, so that the light is diffused, thereby increasing the amount of light emitted laterally by the second light emitting device 20. The second light-emitting device 20 is used as a shared pixel. By adjusting the distance between the light-blocking structure 02 and the second opening K2, it can be ensured that the lateral light output of the second light-emitting device 20 is not blocked. The second light-guiding structure 032 increases the amount of light emitted to the side by the second light-emitting device 20, which can improve the brightness when viewed from a wide viewing angle, thereby reducing power consumption. In addition, in some embodiments, the first light-emitting device 10 and the second light-emitting device 20 are both set to emit light in the shared mode, the first light-guiding structure 031 increases the amount of forward light output of the first light-emitting device 10, and the second light-guiding structure 032 increases the amount of lateral light output of the second light-emitting device 20, thereby balancing the brightness difference between the front view direction and the wide viewing angle direction in the shared mode and improving the overall display effect.

[0070] like Fig.12 As shown, in the direction from the center to the edge of the second light emitting device 20 , the thickness of the third refractive portion 43 gradually increases; the refractive index of the third refractive portion 43 is greater than the refractive index of the fourth refractive portion 44 . Fig.12 The diagram illustrates the optical path of the light emitted by the second light emitting device 20 refracted at the interface between the third refraction portion 43 and the fourth refraction portion 44. The light emitted by the second light emitting device 20 is emitted from the third refraction portion 43 to the fourth refraction portion 44, that is, from the light-dense medium to the light-sparse medium. The refraction angle is smaller than the incident angle, so that the light is deflected laterally, thereby increasing the light output of the second light emitting device 20 at a wide viewing angle. The second light emitting device 20 is used as a shared pixel, and increasing its lateral light output increases the brightness of the second light emitting device 20 at a wide viewing angle, which can reduce power consumption in the shared mode and improve the display effect when viewed at a wide viewing angle.

[0071] like Fig.12As shown, the third refractive portion 43 has a fourth side surface M7 and a fourth bottom surface M8; in the direction from the center of the second light-emitting device 20 to the edge, the distance between the fourth side surface M7 and the fourth bottom surface M8 gradually increases; the angle formed by the fourth side surface M7 and the fourth bottom surface M8 toward the third refractive portion 43 is θ4, 30°≤θ4≤70°. Fig.12 The fourth side surface M7 is shown as a curved surface, and the angle θ4 is defined by the angle formed by the tangent of the fourth side surface M7 and the fourth bottom surface M8. In other embodiments, the fourth side surface M7 is an inclined surface, and the angle θ4 is defined by the slope angle formed by the fourth side surface M7 and the fourth bottom surface M8. In the embodiment of the present invention, the large-angle light emitted by the second light-emitting device 20 is refracted at the interface between the third refractive portion 43 and the fourth refractive portion 44 to deflect the light in the direction of the wide viewing angle, thereby increasing the amount of light emitted by the second light-emitting device 20 in the direction of the wide viewing angle. Setting 30°≤θ2≤70° allows a larger proportion of light to be deflected in the direction of the wide viewing angle, thereby having a better effect on increasing the brightness of the second light-emitting device 20 at a wide viewing angle.

[0072] like Fig.12 As shown, along the first direction a, the width of the second opening K2 is D21, and the width of the second hollow V2 is D22; the light-blocking structure 02 has a fourth opening K4, and along the direction e perpendicular to the plane where the substrate 00 is located, the fourth opening K4 at least partially overlaps with the second light-emitting device 20; along the first direction a, the width of the fourth opening K4 is D23; wherein, D23>D21>D22. Setting D21>D22 enables the second light-guiding structure 032 to make full use of the light emitted by the second light-emitting device 20, and diffuse more light from the second light-emitting device 20 to a large angle, thereby improving the brightness of the second light-emitting device 20 at a large viewing angle. Setting D23>D21, the light-emitting angle of the second light-emitting device 20 can be controlled by adjusting the distance between the light-blocking structure 02 and the second opening K2, so as to ensure the influence of the second light-emitting device 20 as a shared pixel.

[0073] In some embodiments, Fig.13 A schematic diagram of another display panel provided by an embodiment of the present invention, such as Fig.13As shown, the first light-emitting device 10 includes a first light-emitting device 11 of a first color, and the second light-emitting device 20 includes a second light-emitting device 21 of a first color. The colors of the first light-emitting device 11 of the first color and the second light-emitting device 21 of the first color are the same: along the direction e perpendicular to the plane where the substrate 00 is located, the first light-emitting device 11 of the first color overlaps with the first light-guiding structure 031, and the second light-emitting device 21 of the first color overlaps with the second light-guiding structure 032. The width of the first refraction portion 41 overlapping with the first light-emitting device 11 of the first color along the direction e perpendicular to the plane where the substrate 00 is located in the first direction a is D16, and the width of the second hollow portion V2 overlapping with the first light-emitting device 21 of the first color along the direction e perpendicular to the plane where the substrate 00 is located in the first direction a is D26; D26>D16. The first light-guiding structure 031 and the second light-guiding structure 032 have different functions. The structural dimensions of the light-guiding structure 03 are designed according to the sizes of the two light-emitting devices and the functions of the two light-guiding structures 03, and D26>D16 is set, so that the first light-guiding structure 031 on the first light-emitting device 11 of the first color has the function of converging light, and the second light-guiding structure 032 on the first light-emitting device 21 of the first color has the function of diffusing light.

[0074] like Fig.13 As shown, the light-blocking structure 02 has a third opening K3 and a fourth opening K4; along the direction e perpendicular to the plane where the substrate 00 is located, the third opening K3 at least partially overlaps with the first light-emitting device 10, and the fourth opening K4 at least partially overlaps with the second light-emitting device 20. The first light-emitting device 10 includes a first light-emitting device 11 of a first color, and the second light-emitting device 20 includes a second light-emitting device 21 of a first color. The first light-emitting device 11 of the first color and the second light-emitting device 21 of the first color have the same color; wherein the area of ​​the third opening K3 overlapping with the first light-emitting device 11 of the first color is smaller than the area of ​​the fourth opening K4 overlapping with the second light-emitting device 21 of the first color. Such a setting can make the light-emitting area of ​​the shared pixel larger than the light-emitting area of ​​the anti-peeping pixel in pixels of the same color. Generally, the use time of the shared mode will be longer than the use time of the anti-peeping mode. The light-emitting areas of the two pixels are reasonably designed according to the application scenario, so that the space of the entire display area can be reasonably utilized to ensure the number of pixels per unit area of ​​the display panel.

[0075] In some embodiments, Fig.13As shown, the first light-emitting device 10 includes a first light-emitting device 11 of a first color, and the second light-emitting device 20 includes a second light-emitting device 21 of a first color. The first light-emitting device 11 of the first color and the second light-emitting device 21 of the first color have the same color. Along the first direction a, the width of the first opening K1 corresponding to the first light-emitting device 11 of the first color is smaller than the width of the second opening K2 corresponding to the second light-emitting device 21 of the first color. That is, the area of ​​the first opening K1 corresponding to the first light-emitting device 11 of the first color is set to be smaller than the area of ​​the second opening K2 corresponding to the second light-emitting device 21 of the first color. Such a setting can make the light-emitting area of ​​the shared pixel larger than the light-emitting area of ​​the anti-peeping pixel in pixels of the same color. Generally, the use time of the shared mode will be longer than the use time of the anti-peeping mode. The light-emitting areas of the two pixels are reasonably designed according to the application scenario. The area of ​​the second opening K2 is set to be large, which can reduce the current density of the second light-emitting device 20, thereby increasing the service life of the second light-emitting device 20.

[0082] In the embodiment of the present invention, the display panel further comprises a pixel circuit, and the pixel circuit is located between the substrate 00 and the light emitting device 1 ; one pixel circuit is connected to one first light emitting device 10 and one second light emitting device 20 . Fig.19 Schematic diagram of a pixel circuit provided by an embodiment of the present invention. Fig.19As shown, the pixel circuit 30 includes a driving transistor Tm, a first light-emitting control module 31, a second light-emitting control module 32, a first electrode reset transistor T1, and a second electrode reset transistor T2. The first light-emitting control module 31 is connected between the driving transistor Tm and the first electrode of the first light-emitting device 10, and the second light-emitting control module 32 is connected between the driving transistor Tm and the first electrode of the second light-emitting device 20; the first electrode reset transistor T1 is connected to the first electrode of the first light-emitting device 10, and the second electrode reset transistor T2 is connected to the first electrode of the second light-emitting device 20. In the embodiment of the present invention, the first light-emitting device 10 and the second light-emitting device 20 are connected to the same driving transistor Tm, and the driving transistor Tm is used to generate a driving current, and an electrode reset transistor and a light-emitting control module are respectively set for the two light-emitting devices. Assuming that only one electrode reset transistor is set for the two light-emitting devices, the first electrodes of the two light-emitting devices are electrically connected. Even if the light-emitting control modules are set for the two light-emitting devices respectively, the light-emitting brightness will be disturbed because the first electrodes of the two are electrically connected. The setting of the embodiment of the present invention can control the two light-emitting devices to reset and emit light separately, ensuring that the light emission of the two light-emitting devices does not interfere with each other. For example, in the anti-peeping mode, the first light emitting device 10 can emit light while the second light emitting device 20 does not emit light, thereby ensuring the effect of the anti-peeping mode.

For example, in the anti-peeping mode, the first light-emitting control line Emit1 is set to provide an enable signal, while the second light-emitting control line Emit2 does not provide an enable signal, so that the first light-emitting device 10 emits light while the second light-emitting device 20 does not emit light, thereby ensuring the effect of the anti-peeping mode.

In the first display mode, the second light-emitting control line Emit2 provides a non-enable signal in the working cycle of the pixel circuit, that is, the second light-emitting control line Emit2 provides a constant voltage signal, which can reduce display power consumption.

In the light-emitting stage t4, the first light-emitting control line Emit1 provides an enable signal, and the second light-emitting control line Emit2 provides a non-enable signal, and the driving transistor Tm provides a driving current to the first light-emitting device 10 to control the first light-emitting device 10 to emit light.

[0087] The display panel provided in the embodiment of the present invention includes a second display mode; in the second display mode: in the reset stage and the write stage, the first light-emitting control line Emit1 provides a non-enable signal, and the second light-emitting control line Emit2 provides a non-enable signal; in the light-emitting stage, the first light-emitting control line Emit1 provides an enable signal, and the second light-emitting control line Emit2 provides an enable signal.
