When the display panel is tilted, the reflecting element rotates relative to the accommodating element, so that there is an angle between the gravity line of the reflecting element and the normal line of the light-emitting side of the display panel, so that the reflecting element reflects more ambient light to one side of the anti-peeping area, thereby enhancing the anti-peeping effect of the display panel on that side, and the enhanced anti-peeping effect does not require electric energy to drive. The present application also provides a display device.

[0002] Organic Light-Emitting Diode (OLED) display panels are widely used in the field of display technology due to their advantages such as self-luminescence, light weight, high color saturation, and wide viewing angle.

[0003] Although the light-emitting characteristics of OLED light-emitting elements make OLED display panels have a wider viewing angle, users sometimes also hope that the viewing angle of OLED display panels can be narrowed as needed. The narrow viewing angle display achieves anti-peeping effect to prevent screen information leakage, thereby protecting commercial secrets and personal privacy. At present, OLED display panels generally need to be driven by electric energy to achieve the anti-peeping effect on one side, which not only increases the energy consumption of OLED display panels, but also increases the cost of using OLED display panels.

The display panel 30 also includes a plurality of anti-peeping components 34, an encapsulation layer 35, a plurality of reflective elements 36, and a light shielding layer 37. At least part of one of the anti-peeping components 34 is disposed in one of the accommodating grooves 331a. The encapsulation layer 35 is disposed on the surface of the pixel defining layer 331 facing away from the driving circuit layer 32, and covers a plurality of the anti-peeping components 34. Part of the encapsulation layer 35 is located in the plurality of sub-pixel regions A1, and part of the encapsulation layer 35 is located in the non-sub-pixel region A2. A plurality of reflective elements 36 are embedded in the side of the encapsulation layer 35 facing away from the pixel defining layer 331, and at least one of the reflective elements 36 is located in one of the peep-proof regions A21.

The light shielding layer 37 shields the ambient light directed toward the light-emitting side of the anti-peeping area A21, so that the ambient light cannot be emitted from the light-emitting side of the anti-peeping area A21, and prevents the ambient light reflected by the anti-peeping component 34 from being emitted from the positive viewing direction of the light-emitting side of the display panel 30, thereby affecting the image display in the positive viewing direction, wherein the positive viewing direction is parallel to the normal of the light-emitting side of the display panel 30.

When viewing the display panel 30 from the light-emitting side of the display panel 30, if the angle between the direction of viewing the display panel 30 and the normal to the light-emitting side of the display panel 30 is greater than a predetermined angle, then the direction of viewing the display panel 30 is the wide viewing angle direction of the display panel 30.

The number of the anti-peeping components 34 in each anti-peeping area A21 can be one or more, and accordingly, the number of the containing grooves 331a in each anti-peeping area A21 can be one or more. For example, Figure 4 and Figure 5 The number of the anti-peeping component 34 in the anti-peeping area A21 is one, Figure 6 The number of the anti-peeping components 34 in the anti-peeping area A21 is two, and the two anti-peeping components 34 are arranged at intervals along the second direction 002.

[0061] In this application implementation mode, please refer to Figure 3Each of the peep-proof components 34 includes a shading element 341, a containing element 342, a solution 343 and a reflecting element 344. The shading element 341 is disposed in the containing groove 331a and connected to the inner wall of the containing groove 331a. The shape and size of the shading element 341 match the shape and size of the inner wall of the containing groove 331a. The containing element 342 is a hollow closed element as a whole. It is at least partially disposed on the inner wall of the shading element 341 and extends out from the side of the pixel defining layer 331 facing away from the driving circuit layer 32. That is, the shading element 341 is located between the inner wall of the containing groove 331a and the containing element 342. The solution 343 is disposed inside the accommodating element 342, the reflective element 344 is disposed in the solution 343, and both the solution 343 and the reflective element 344 are sealed in the accommodating element 342, and the solution 343 is used to suspend the reflective element 344. The ambient light directed toward the anti-peeping component 34 passes through the accommodating element 342 and the solution 343 and is directed toward the reflective element 344, and the reflective element 344 is used to reflect the ambient light directed toward itself to the light-emitting side of the display panel 30, and the shading element 341 is used to shield the ambient light reflected by the reflective element 344 to the encapsulation layer 35.

[0062] In an exemplary embodiment, the inner wall of the accommodating groove 331a may be a curved surface, and the entire shading element 341 may be a curved structure. The shape of the inner bottom of the accommodating element 342 matches the shape of the bottom of the reflecting element 344, and the size of the inner bottom of the accommodating element 342 matches the size of the bottom of the reflecting element 344.

[0063] See also Figure 3 , Figure 3 The display panel 30 is not tilted (ie, in a horizontal state), that is, the light-emitting side of the display panel 30 is perpendicular to the gravity direction. The reflective element 344 has a gravity line, Figure 3 In the embodiment, the gravity line direction of the reflective element 344 is parallel to the gravity direction and parallel to the normal line of the light emitting side of the display panel 30. Figure 8 and Fig. 9 , Figure 8 Schematic diagram of the structure of the display panel in the first anti-peeping mode disclosed in the second embodiment of the present application, Fig. 9 Schematic diagram of the structure of the display panel in the second anti-peeping mode disclosed in the second embodiment of the present application, wherein: Figure 8 The display panel 30 shown is tilted to one side, for example, the display panel 30 is tilted to the left side, that is, the height of the left side of the display panel 30 is lower than the height of the right side (eg, Figure 8 shown); Fig. 9The display panel 30 shown is tilted to the other side, for example, the display panel 30 is tilted to the right side, that is, the height of the left side of the display panel 30 is higher than the height of the right side (eg, Fig. 9 As shown). The solution 343 suspends the reflective element 344. When the display panel 30 is tilted, that is, the light-emitting side of the display panel 30 is not perpendicular to the gravity direction, the accommodating element 342 can rotate relative to the reflective element 344. Since the gravity line direction of the reflective element 344 is consistent with the gravity direction, the gravity line of the reflective element 344 and the normal line of the light-emitting side of the display panel 30 have an included angle of a preset angle. Since the gravity line of the reflective element 344 and the normal line of the light-emitting side of the display panel 30 have an included angle, the reflective element 344 reflects more of the ambient light to the light-emitting side of the sub-pixel area A1 on one side of the anti-peeping area A21, and reflects less of the ambient light to the light-emitting side of the sub-pixel area A1 on the other side of the anti-peeping area A21. For example, please refer to Figure 8 , the display panel 30 rotates counterclockwise, so that the height of the left side is lower than that of the right side. Under the action of gravity, the reflective element 344 rotates clockwise relative to the accommodating element 342, so that the gravity line of the reflective element 344 is parallel to the gravity direction. The reflective element 344 reflects more of the ambient light to the sub-pixel area A1 on the right side of the anti-peeping area A21, thereby enhancing the anti-peeping effect on the right side. The reflective element 344 reflects less of the ambient light to the sub-pixel area A1 on the left side of the anti-peeping area A21, thereby weakening the anti-peeping effect on the left side. For another example, please refer to Fig. 9 The display panel 30 rotates clockwise so that the height of the left side is higher than that of the right side. Under the action of gravity, the reflective element 344 rotates counterclockwise relative to the accommodating element 342 so that the gravity line of the reflective element 344 is parallel to the gravity direction. The reflective element 344 reflects more of the ambient light to the sub-pixel area A1 on the left side of the anti-peeping area A21, thereby enhancing the anti-peeping effect on the left side. The reflective element 344 reflects less of the ambient light to the sub-pixel area A1 on the right side of the anti-peeping area A21, thereby weakening the anti-peeping effect on the right side.

[0064] It is understandable that when the display panel 30 is tilted, due to the effect of gravity and the suspension effect of the solution 343, the reflective element 344 will rotate relative to the accommodating element 342, so that the gravity line of the reflective element 344 remains parallel to the gravity direction, and then there is a certain angle between the gravity line of the reflective element 344 and the normal line of the light-emitting side of the display panel 30. The reflective element 344 reflects more of the ambient light to one side of the anti-peeping area A21, thereby enhancing the anti-peeping effect of this side of the display panel 30. Moreover, if the anti-peeping effect of one side of the display panel 30 is to be enhanced, it can be achieved by tilting the display panel 30 in the direction opposite to the side, without the need for electric energy drive, and will not increase the energy consumption and use cost of the display panel 30.

[0065] It should be noted that the solution 343 also has a lubricating effect to reduce the friction that the reflective element 344 needs to overcome when rotating relative to the accommodating element 342. The preset angle is greater than 0 degrees and less than 180 degrees, for example, 1 degree, 10 degrees, 30 degrees, 45 degrees, 70 degrees, 90 degrees, 95 degrees, 120 degrees, 135 degrees, 145 degrees, 164 degrees, 179 degrees, or other values, and the present application does not impose specific restrictions on this.

[0066] In an exemplary embodiment, the reflective element 344 is solid. In other embodiments, the reflective element 344 may be a metal solution, and the metal solution and the solution 343 are immiscible with each other, and the density of the metal solution is greater than that of the solution 343 .

The reflective element 344 can be roughly a hemispherical structure or a hemispherical structure as a whole. The reflective element 344 includes a connected curved surface and a plane. The plane is arranged toward the light-emitting side of the display panel 30. The plane is the surface of the reflective element 344 that reflects the ambient light, that is, the plane is the reflective surface of the reflective element 344. When the display panel 30 is horizontal, the curved surface is arranged toward the shading element 341, the plane is arranged toward the shading layer 37, and the plane is perpendicular to the gravity line of the reflective element 344.

The reflective element 344 can be a spherical structure or an ellipsoidal structure as a whole, and the reflective element 344 includes a first curved surface 344a and a second curved surface 344b connected to each other, wherein the first curved surface 344a and the second curved surface 344b have the same shape and size, and the second curved surface 344b is arranged toward the light-emitting side of the display panel 30, and the second curved surface 344b is the surface of the reflective element 344 reflecting the ambient light, that is, the second curved surface 344b is the reflective surface of the reflective element 344. When the display panel 30 is horizontal, the first curved surface 344a is arranged toward the shading element 341, and the arc connecting the first curved surface 344a and the second curved surface 344b is perpendicular to the gravity line of the reflective element 344.

[0069] See also Fig.12 and Fig.13 , Fig.12 Schematic diagram of a third three-dimensional structure of the reflective element of the display panel disclosed in the second embodiment of the present application, Fig.13 for Fig.12 The schematic diagram of the top view of the reflective element shown in the figure. The reflective element 344 includes a reflective portion 3441 and two shading portions 3442. The reflective portion 3441 is generally a hemispherical structure or a hemispherical structure. The reflective portion 3441 includes a connected arc surface and a plane surface. The plane surface is arranged toward the light-emitting side of the display panel 30. The two shading portions 3442 are arranged on a partial plane surface of the reflective portion 3441 and are arranged at intervals from each other so that the partial plane surface of the reflective portion 3441 exposes the two shading portions 3442. The partial plane surface exposed by the reflective portion 3441 is the surface of the reflective element 344 that reflects the ambient light, that is, the partial plane surface exposed by the reflective portion 3441 is the reflection surface of the reflective element 344. When the display panel 30 is horizontal, the arc surface of the reflective portion 3441 is disposed toward the shading element 341 , the plane is disposed toward the shading layer 37 , and the plane is perpendicular to the gravity line of the reflective element 344 , and the plane of the reflective portion 3441 is disposed toward the shading layer 37 .

[0070] It can be understood that the light shielding portion 3442 is used to shield the ambient light reflected by the plane of the reflective element 344, so that the shielded ambient light cannot be emitted to the light-emitting side of the display panel 30. For example, Fig.13 In the embodiment, the ambient light reflected by the reflective element 344 cannot be emitted toward the light emitting side of the display panel 30 from its upper and lower sides. The ambient light reflected by the reflective element 344 is emitted toward the light emitting side of the display panel 30 from the left and right sides, thereby realizing the anti-peeping effect on the opposite sides of the display panel 30.

[0071] See also Fig.14 , Fig.14 The fourth stereoscopic structural schematic diagram of the reflective element of the display panel disclosed in the second embodiment of the present application. The reflective element 344 includes a reflective body 3443 and a first spiral 3444. The reflective body 3443 can be roughly a semi-cylindrical structure as a whole. The reflective body 3443 includes a plane and a curved surface connected to each other. The first spiral 3444 is arranged on the left half of the plane and connected to the curved surface of the reflective body 3443. The surface of the first spiral 3444 connected to the right half of the plane is a spiral surface (i.e., a spiral surface), and the number of turns corresponding to the spiral surface is 0.25 turns. The right half of the plane and the spiral surface are used to reflect the ambient light, that is, the right half of the plane and the spiral surface are the reflective surfaces of the reflective element 344. When the display panel 30 is horizontal, the curved surface of the reflective body 3443 is arranged toward the shading element 341, the plane of the reflective body 3443 is arranged toward the shading layer 37, and the plane is perpendicular to the gravity line of the reflective element 344. It can be understood that in the embodiment of the present application, the left half and the right half of the plane refer to the plane from Fig.14 The dotted line in the figure divides the plane of the reflective body 3443 into two areas, left and right. For the convenience of understanding and describing this application, the area located in the left part is defined as the left half of the plane, and the area located in the right part is defined as the right half of the plane. Fig.15 and Fig.16 The left half and the right half of the plane shown in can also be defined in the above manner, which will not be described in detail below.

[0072] It can be understood that the ambient light entering the display panel 30 from the outside has a certain angle range, and the spiral surface of the first spiral body 3444 can reflect the ambient light in a larger angle range, thereby increasing the utilization rate of the ambient light and improving the anti-peeping capability of the display panel 30.

[0073] See also Fig.15 , Fig.15The fifth three-dimensional structural schematic diagram of the reflective element of the display panel disclosed in the second embodiment of the present application.

The reflective body 3443 includes a plane and a curved surface connected to each other. The second spiral 3445 is arranged on the right half of the plane and connected to the curved surface of the reflective body 3443. The surface of the second spiral 3445 connected to the left half of the plane is a spiral surface, and the number of turns corresponding to the spiral surface is 0.25. The left half of the plane and the spiral surface are used to reflect the ambient light, that is, the left half of the plane and the spiral surface are the reflective surfaces of the reflective element 344. When the display panel 30 is horizontal, the curved surface of the reflective body 3443 is arranged toward the shading element 341, the plane of the reflective body 3443 is arranged toward the shading layer 37, and the plane is perpendicular to the gravity line of the reflective element 344.

[0074] It can be understood that the ambient light entering the display panel 30 from the outside has a certain angle range, and the spiral surface of the second spiral body 3445 can reflect the ambient light in a larger angle range, thereby increasing the utilization rate of the ambient light and improving the anti-peeping capability of the display panel 30.

[0075] See also Fig.16 , Fig.16The sixth three-dimensional structural diagram of the reflective element of the display panel disclosed in the second embodiment of the present application. The reflective element 344 includes a reflective body 3443, a first spiral 3444 and a second spiral 3445. The reflective body 3443 can be a semi-cylindrical structure as a whole. The reflective body 3443 includes a plane and an arc surface connected to each other. The first spiral 3444 is arranged in the left half of the plane and connected to the arc surface of the reflective body 3443. The second spiral 3445 is arranged in the right half of the plane and connected to the arc surface of the reflective body 3443. The surfaces of the first spiral 3444 and the second spiral 3445 connected to each other are both spiral surfaces. The spiral surface of the first spiral 3444 and the spiral surface of the second spiral 3445 have opposite rotation directions, and the number of turns corresponding to the spiral surface of the first spiral 3444 and the spiral surface of the second spiral 3445 are both 0.25 turns. The helical surface of the first spiral 3444 and the helical surface of the second spiral 3445 are used to reflect the ambient light, that is, the helical surface of the first spiral 3444 and the helical surface of the second spiral 3445 are the reflective surfaces of the reflective element 344. When the display panel 30 is horizontal, the arc surface of the reflective body 3443 is arranged toward the shading element 341, the plane is arranged toward the shading layer 37, and the plane is perpendicular to the gravity line of the reflective element 344.

[0076] In an exemplary embodiment, the material of the reflective element 344 may include a material with good reflective properties such as metal. In other embodiments, the material of the reflective element 344 may also include plastic, and the surface of the reflective element 344 is coated with a reflective film so that the reflective element 344 can reflect the ambient light.

[0077] See also Fig.17 , Fig.18 and Fig.19 , Fig.17 is a partial top view of the structure of the display panel disclosed in the third embodiment of the present application, Fig.18 for Fig.17 The cross-sectional schematic diagram of the display panel along the XVIII-XVIII direction is shown. Fig.19 for Fig.18 The display panel 40 of the third embodiment is different from the display panel 30 of the second embodiment in that the anti-peeping component 34 of the display panel 40 of the third embodiment further includes two limiting elements 345. For the description of the similarities between the display panel 40 of the third embodiment and the display panel 30 of the second embodiment, please refer to the relevant description of the display panel 30 of the second embodiment, which will not be repeated here.

[0078] Specifically, the two limiting elements 345 are arranged at intervals along the second direction 002 and are located on the inner wall of the accommodating element 342. The two limiting elements 345 are located on the side of the reflecting element 344 facing the light shielding layer 37 and are in contact with the reflecting element 344. The limiting elements 345 are used to limit the reflecting element 344 from rotating relative to the plane formed by the accommodating element 342 in the second direction 002 and the third direction 003, so that the reflecting element 344 rotates relative to the plane formed by the accommodating element 342 in the first direction 001 and the third direction 003. The first direction 001 may be the length direction of the display panel 40, the second direction 002 may be the width direction of the display panel 40, the third direction 003 may be the thickness direction of the display panel 40, and the first direction 001, the second direction 002 and the third direction 003 are perpendicular to each other.

[0079] It is understandable that the light-emitting side of the display panel 40 will not always be horizontal, that is, the light-emitting side of the display panel 40 will not always be perpendicular to the direction of gravity. Fig.17 For example, it is desired that the display panel 40 be protected from peeping along both sides of the first direction 001, but the display panel 40 tilting along both sides of the second direction 002 will achieve protection from peeping along the second direction 002. Therefore, two limiting elements 345 are provided along the second direction 002, and the reflective element 344 will not rotate relative to the plane formed by the accommodating element 342 in the second direction 002 and the third direction 003, and the reflective element 344 can only rotate relative to the plane formed by the accommodating element 342 in the first direction 001 and the third direction 003, so that the display panel 40 can only be protected from peeping along both sides of the first direction 001, that is, the limiting elements 345 are used to limit the rotation direction of the reflective element 344.

[0080] In an exemplary embodiment, see Fig.18 In the third direction 003, the two limiting elements 345 are located in the middle position of the accommodating element 342, that is, the distance between the end of the accommodating element 342 facing the shading layer 37 and the limiting element 345 is equal to the distance between the end of the accommodating element 342 facing away from the shading layer 37 and the limiting element 345.

[0081] In other implementations, the two limiting elements 345 may be connected to each other as one body.

[0082] In summary, in the display panel and display device 1 provided in the embodiment of the present application, the display panel includes a plurality of sub-pixel areas A1 and a plurality of anti-peeping areas A21, and one of the anti-peeping areas A21 is arranged between two adjacent sub-pixel areas A1. The display panel also includes a light-emitting component 33, a plurality of anti-peeping components 34, an encapsulation layer 35 and a light-shielding layer 37. The light-emitting component 33 includes a pixel defining layer 331, the pixel defining layer 331 is provided with a plurality of accommodating grooves 331a, and at least one of the accommodating grooves 331a is located in one of the sub-pixel areas A1, and one of the anti-peeping components 34 is arranged in one of the accommodating grooves 331a. The encapsulation layer 35 covers the plurality of anti-peeping components 34 to the pixel defining layer 331. The light-shielding layer 37 is arranged on the side of the encapsulation layer 35 facing away from the plurality of anti-peeping components 34, and is located in each of the anti-peeping areas A21. Each of the peep-proof components 34 includes a sealed accommodating element 342, a solution 343, and a reflective element 344. The accommodating element 342 is disposed in the accommodating groove 331a, the solution 343 is disposed inside the accommodating element 342, and the reflective element 344 is disposed in the solution 343. The solution 343 suspends the reflective element 344. The ambient light directed toward the peep-proof component 34 passes through the accommodating element 342 and the solution 343 and is directed toward the reflective element 344. The reflective element 344 reflects the ambient light directed toward itself to the light-emitting side of the display panel 30, and the shading element 341 blocks the ambient light reflected by the reflective element 344 to the encapsulation layer 35. When the display panel is in a horizontal state, the gravity line direction of the reflective element 344 is parallel to the normal line of the light-emitting side of the display panel. When the display panel 30 is in a tilted state, the reflective element 344 rotates relative to the accommodating element 342, so that the gravity line of the reflective element 344 and the normal line of the light-emitting side of the display panel have a preset angle. Therefore, when the display panel is tilted, due to the effect of gravity and the suspension effect of the solution 343, the reflective element 344 will rotate relative to the accommodating element 342, so that the gravity line of the display panel is parallel to the gravity direction, and then the gravity line of the reflective element 344 and the normal line of the light-emitting side of the display panel 30 have a certain angle. The ambient light reflected by the reflective element 344 is more directed to one side of the anti-peeping area A21, thereby enhancing the anti-peeping effect of the display panel on that side. Moreover, if the anti-peeping effect of one side of the display panel is to be enhanced, it can be achieved by tilting the display panel in the direction opposite to that side, without the need for electric energy drive, and thus will not increase the energy consumption and use cost of the display panel.
