[0030] The present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments. It is to be understood that the specific embodiments described herein are only used to explain the present invention, rather than to limit the present invention. It should also be noted that, for ease of description, only parts related to the present invention, rather than all structures, are shown in the accompanying drawings.

[0031] It should be noted that the terms "first", "second", etc. in the specification and claims of the present invention and the above-mentioned drawings are used to distinguish similar objects, and are not necessarily used to describe a specific order or sequence. It should be understood that the data used in this way can be interchanged where appropriate, so that the embodiments of the present invention described herein can be implemented in an order other than those illustrated or described herein. In addition, the terms "including" and "having" and any variations thereof are intended to cover non-exclusive inclusions, for example, a system, product or device comprising a series of units is not necessarily limited to those steps or units clearly listed, but may include other units that are not clearly listed or inherent to these products or devices.

[0032] In the prior art, there is a demand for different light-emitting angles of the light-emitting elements in the light-emitting panel, that is, in the normal light-emitting state, the light-emitting elements in the light-emitting panel need to emit light at a larger angle, and in the anti-peeping state, the light-emitting elements in the light-emitting panel need to emit light at a relatively smaller angle. Furthermore, for the anti-peeping state, the existing light-emitting panels include a variety of anti-peeping methods, such as anti-peeping films, white anti-peeping and black anti-peeping.

[0033] Among them, when the light-emitting panel has an anti-peeping function, the highest grayscale screen brightness is reduced at a wide viewing angle to achieve the anti-peeping function. From a visual effect, the screen brightness is low, that is, the anti-peeping function is achieved by reducing the white state brightness, which is called white state anti-peeping. By setting an opaque retaining wall structure in the light-emitting panel, the light emitted by the light-emitting element in the light-emitting panel will not be able to be emitted in the direction of the wide viewing angle. Therefore, the corresponding visual effect at a wide viewing angle is black, that is, a black screen is observed at a wide viewing angle, and the actual display screen information cannot be observed. This effect is the black state anti-peeping effect.

[0034] Furthermore, although the white state anti-peeping function can realize the anti-peeping function to a certain extent, specific information can still be identified for the commonly used white background and black text screen at a wide viewing angle, and the anti-peeping effect needs to be improved. The anti-peeping film cannot be switched and has a limited scope of use. Compared with the white state anti-peeping in the relevant prior art, the black state anti-peeping is more conducive to improving the anti-peeping effect of the light-emitting panel and the protection function of user privacy. However, the black state anti-peeping needs to provide an overall area for placing the shading structure, that is, it occupies the setting space of the light-emitting panel, which is not conducive to achieving a thin design, and the shading structure also affects the viewing angle of the light-emitting element under normal conditions, that is, it affects the luminous effect of the light-emitting panel.

[0035] To solve the above problems, the embodiment of the present invention discloses a light-emitting panel, a display device and a backlight module, wherein the light-emitting panel includes: a driving substrate; a light-emitting element, which is located on one side of the driving substrate and is electrically connected to the driving substrate; a light-emitting adjustment module, which includes a lampshade and a posture adjustment unit; the lampshade surrounds at least one light-emitting element; the posture adjustment unit is connected to the lampshade and is used to adjust the posture of the lampshade; the light-emitting panel includes a first light-emitting state and a second light-emitting state, in the first light-emitting state, the lampshade includes a first posture and the light-emitting element in the area surrounded by the lampshade has a first light-emitting angle α, and in the second light-emitting state, the lampshade includes a second posture and the light-emitting element in the area surrounded by the lampshade has a second light-emitting angle β, wherein α>β. The technical solution provided by the present invention adjusts the posture of the lampshade through the posture adjustment module, so as to achieve different positions and postures between the lampshade and the light-emitting element, thereby adjusting the light-emitting angle of the light-emitting element, and ensuring that the light-emitting panel has a good light-emitting effect in different states, that is, large light-emitting angle and small light-emitting angle. Compared with the prior art that provides additional space for accommodating a light-blocking structure, the lampshade for adjusting the light output angle of the light-emitting element in the present invention is disposed around the light-emitting element, which can reduce the overall space of the light-emitting panel and is conducive to achieving a thin design.

[0036] The above is the core idea of ​​the present invention. The technical scheme 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. 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.

[0037] Figure 1 A schematic diagram of the structure of a light-emitting panel provided by an embodiment of the present invention, Figure 2 A schematic diagram of the structure of another light-emitting panel provided by an embodiment of the present invention, Figure 3 A schematic diagram of the structure of another light-emitting panel provided by an embodiment of the present invention, Figure 4 A schematic diagram of the structure of another light-emitting panel provided by an embodiment of the present invention, Figure 5 for Figure 1 A schematic cross-sectional view along the A-A' direction, Figure 6 for Figure 1 Another cross-sectional diagram along the A-A' direction, Figure 7 for Figure 1 Another cross-sectional diagram along the A-A' direction, Figure 8 for Figure 1 Another cross-sectional diagram along the A-A' direction, Fig. 9 for Figure 1 Another cross-sectional diagram along the A-A' direction, Fig.10 for Figure 1 Another cross-sectional diagram along the A-A' direction, see Figures 1 to 10As shown, an embodiment of the present invention provides a light-emitting panel 10, which includes: a driving substrate 100; a light-emitting element 200, which is located on one side of the driving substrate 100 and is electrically connected to the driving substrate 100; a light-emitting adjustment module 300, which includes a lampshade 310 and a posture adjustment unit 320; the lampshade 310 surrounds at least one light-emitting element 200; the posture adjustment unit 320 is connected to the lampshade 310, and is used to adjust the posture of the lampshade 310; the light-emitting panel 10 includes a first light-emitting state and a second light-emitting state, in the first light-emitting state, the lampshade 310 includes a first posture and the light-emitting element 200 in the area around the lampshade 310 has a first light-emitting angle α, and in the second light-emitting state, the lampshade 310 includes a second posture and the light-emitting element 200 in the area of ​​the lampshade 310 has a second light-emitting angle β, wherein α>β.

[0038] Specifically, refer to Figure 1 As shown, the light-emitting panel 10 includes a driving substrate 100 and a plurality of light-emitting elements 200 located on one side of the driving substrate 100. The light-emitting effect of the light-emitting panel 10 is achieved by the light emission of the light-emitting elements 200. By way of example, the light emitted by the light-emitting panel 10 can be used to achieve the display effect of a display device, and can also be used to achieve the backlight effect of a backlight module. The embodiment of the present invention does not make any specific limitation on this.

[0039] Furthermore, the light emitting panel 10 further includes a light output adjustment module 300, and the light output adjustment module 300 includes a lampshade 310, wherein Figure 1 As shown, the lampshade 310 surrounds a light emitting element 200; Figures 2 to 4 As shown, the lampshade 310 may also surround a plurality of light emitting elements 200. The number of light emitting elements 200 surrounded by the lampshade 310 in the embodiment of the present invention is not specifically limited. When the lampshade 310 surrounds a plurality of light emitting elements 200, the shape of the lampshade 310 away from the driving substrate 100 along the thickness direction of the light emitting panel 10 may be a rectangle, for example Figure 2 As shown; the shape of the lampshade 310 away from the driving substrate 100 may be circular, for example Figure 3 As shown; the shape of the lampshade 310 away from the driving substrate 100 can be a triangle, for example Figure 4 As shown, the embodiment of the present invention does not specifically limit the shape of the lampshade 310. At the same time, the multiple light-emitting elements 200 surrounded by each lampshade 310 can realize synchronous light display, ensure the light emitting synchronization of the light-emitting panel 10, and ensure the light emitting balance of the light-emitting panel 10 as a whole.

[0040] Furthermore, the light output adjustment module 300 also includes a posture adjustment unit 320, and the posture adjustment unit 320 is connected to the lampshade 310, and the position and posture of the lampshade 310 are adjusted based on the posture adjustment unit 320, so that the lampshade 310 has different phase position relationships with the light-emitting element 200, and the lampshade 310 is a light-blocking structure, that is, the posture of the lampshade 310 can be adjusted to ensure that the light-emitting element 200 has different light output viewing angles. Since the lampshade 310 is arranged around the light-emitting element 200, that is, the setting space of the lampshade 310 can be reused in the free area between different light-emitting elements 200, that is, when different viewing angles are achieved by different postures of the lampshade 310 and the light-emitting element 200, the overall setting space of the light-emitting panel 10 can also be reduced, which is conducive to realizing a thin design of the light-emitting panel 10. For example, refer to Figures 5 to 10 As shown, there are various connection modes between the posture adjustment unit 320 and the lampshade 310, that is, the posture adjustment unit 320 can realize the diversity of position adjustment between the lampshade 310 and the surrounding light-emitting element 200, thereby ensuring that the light-emitting viewing angle of the light-emitting element 200 is adjusted by changing the position of the lampshade 310, that is, when a large viewing angle is required, the position of the lampshade 310 is changed to reduce the obstruction of the viewing angle of the light-emitting element 200, and when a small viewing angle is required, the position of the lampshade 310 is changed to increase the obstruction of the viewing angle of the light-emitting element 200, and the small viewing angle requirement can be the working state of the light-emitting panel 10 in the anti-peep mode.

[0041] Furthermore, the light-emitting panel 10 includes a first light-emitting state and a second light-emitting state. In the first light-emitting state, the lampshade 310 and the light-emitting element 200 in the surrounding area have a first light-emitting angle α, that is, a first posture, through the posture adjustment unit 320. Figure 5 , Figure 7 and Fig. 9 In the second light-emitting state, the position adjustment unit 320 is used to achieve that the lampshade 310 and the light-emitting element 200 in the surrounding area have a second light-emitting angle β, that is, a second position. For details, please refer to Figure 6 , Figure 8 and Fig.10As shown. The first light emitting angle α in the first light emitting state is compared with the second light emitting angle β in the second light emitting state, α>β, that is, the light emitting angle of the light emitting element 200 in the first light emitting state is greater than the light emitting angle of the light emitting element 200 in the second light emitting state. Based on this, the second light emitting state can be used as the anti-peeping state of the light emitting panel 10. In other words, by adjusting the posture of the lampshade 310 by the posture adjustment unit 320, different positional relationships between the lampshade 310 and the light emitting element 200 surrounding it are achieved, such as the first posture and the second posture, thereby achieving different light emitting angles of the light emitting element 200, namely the first light emitting state and the second light emitting state, thereby ensuring that the light emitting panel 10 has a light emitting state that is more in line with the requirements under the viewing angle requirements of different light emitting elements 200, thereby ensuring the light emitting effect of the light emitting panel 10.

[0042] In summary, the light-emitting panel provided in the embodiment of the present invention adjusts the position of the lampshade through the position adjustment unit, so that the lampshade and the light-emitting element around it have different positions, that is, the light-emitting element has different light-emitting angles. The light-emitting angle can be larger in the normal light-emitting state and smaller in the anti-peeping state, thereby ensuring the light-emitting effect of the light-emitting panel in different states.

[0043] Continue to refer Figures 5 to 10 As shown, the lampshade 310 includes a lampshade body 311 and a first end 312 of the lampshade, and the first end 312 of the lampshade is located on the side of the lampshade body 311 away from the driving substrate 10; the posture adjustment unit 320 is used to adjust the distance between the first end 312 of the lampshade and the driving substrate 100 to L1 in the first light-emitting state, and to adjust the distance between the first end 312 of the lampshade and the driving substrate 100 to L2 in the second light-emitting state, wherein L1<L2.

[0044] The lampshade 310 includes a lampshade body 311 and a lampshade first end 312, and the lampshade first end 312 is an end point of the lampshade body 311 away from the driving substrate 100. In different light-emitting states, the posture adjustment unit 320 adjusts the posture of the lampshade 310 to achieve different distances between the lampshade first end 312 and the driving substrate 100, thereby achieving different light blocking conditions of the lampshade 310 for the light-emitting element 200, and further achieving different light-emitting angles of the light-emitting element 200.

[0045] Specific, combined Figures 5 to 10 As shown, the lampshade 310 and the posture kit unit 320 surrounding the light emitting element 200 are arranged in a flexible manner. Figure 5 , Figure 7 and Fig. 9As shown, in the first light-emitting state, the distance between the first end 312 of the lampshade and the driving substrate 100 is L1 through the posture adjustment unit 320, and then through the shielding of the lampshade 310, the light-emitting element 200 has a first light output angle α. Figure 6 , Figure 8 and Fig.10 As shown, in the second light-emitting state, the distance between the second end 312 of the lampshade and the driving substrate 100 is L2 through the position adjustment unit 320, and then through the shielding of the lampshade 310, the light-emitting element 200 has a second light-emitting angle β. Further, L1 is adjusted to be less than L2, that is, when the distance is L1 (in the first light-emitting state), the lampshade body 311 of the lampshade 310 drives the first end 312 of the lampshade to block the light-emitting element 200 less from the viewing angle, and when the distance is L2 (in the second light-emitting state), the lampshade body 311 of the lampshade 310 drives the first end 312 of the lampshade to block the light-emitting element 200 more from the viewing angle. In other words, by adjusting the position of the lampshade 310 by the position adjustment unit 320, different light-emitting viewing angles of the light-emitting element 200 are achieved. Specifically, by adjusting the distance between the first end 312 of the lampshade and the driving substrate 100, it is ensured that the light-emitting panel 10 has a light-emitting state that is more in line with the requirements under the viewing angle requirements of different light-emitting elements 200, thereby ensuring the light-emitting effect of the light-emitting panel 10.

[0046] Continue to refer Figures 5 to 8 As shown, the posture adjustment unit 320 includes a first magnetic adjustment section 320A and a second magnetic adjustment section 320B; the first magnetic adjustment section 320A is fixedly provided with the second magnetic adjustment section 320B for connecting with the lampshade 310 and the second magnetic adjustment section 320B is movably provided; in the first luminous state, the directions of the magnetic fields in the first magnetic adjustment section 320A and the second magnetic adjustment section 320B are opposite, and in the second luminous state, the directions of the magnetic fields in the first magnetic adjustment section 320A and the second magnetic adjustment section 320B are the same.

[0047] Among them, the posture adjustment unit 320 includes a first magnetic adjustment section 320A and a second magnetic adjustment section 320B. By adjusting the direction of the magnetic field input between the first magnetic adjustment section 320A and the second magnetic adjustment section 320B, two situations are achieved: the first magnetic adjustment section 320A and the second magnetic adjustment section 320B have the same magnetic field direction and the second magnetic adjustment section 320B have different magnetic field directions. Specifically, when the magnetic field directions in the first magnetic adjustment section 320A and the second magnetic adjustment section 320B are opposite, the first magnetic adjustment section 320A and the second magnetic adjustment section 320B are in an attractive state, and when the magnetic field directions in the first magnetic adjustment section 320A and the second magnetic adjustment section 320B are the same, the first magnetic adjustment section 320A and the second magnetic adjustment section 320B are in a repulsive state. And the positional relationship between the first magnetic adjustment section 320A and the second magnetic adjustment section 320B is adjusted by the repulsion or attraction between the first magnetic adjustment section 320A and the second magnetic adjustment section 320B, thereby driving the lampshade 310 to move to achieve different light emitting angles of the light emitting element 200, that is, to achieve different light emitting states of the light emitting panel 10, thereby ensuring the light emitting effect of the light emitting panel 10. The lampshade 320 adjusts the position through the direction of the magnetic magnetic field, that is, the adjustment of the position of the lampshade 320 and the light emitting element 200 is simple, easy to achieve, and cost-controlled.

[0048] Exemplary, reference Figure 5 and Figure 7 As shown, in the first luminous state, the magnetic field directions of the first magnetic adjustment section 320A and the second magnetic adjustment section 320B are opposite, and when the first magnetic adjustment section 320A is fixed, the second magnetic adjustment section 320B moves closer to the first magnetic adjustment section 320B, thereby driving the lampshade 310 to achieve the first posture state. Figure 6 and Figure 8 As shown, in the second luminous state, the directions of the magnetic fields in the first magnetic adjustment section 320A and the second magnetic adjustment section 320B are the same, and when the first magnetic adjustment section 320A is fixedly arranged, there is a certain distance between the second magnetic adjustment section 320B and the first magnetic adjustment section 320B, so as to ensure the repulsive relationship between the second magnetic adjustment section 320B and the first magnetic adjustment section 320A, thereby driving the lampshade 310 to achieve the second posture state. Exemplarily, the first magnetic adjustment section 320A can be a coil structure, and the second magnetic adjustment section 320B can be an electromagnetic coil structure. By passing a magnetic field in the same direction as the electromagnetic coil into the coil of the first magnetic adjustment section 320A, a state in which the two repel each other, i.e., the second luminous state, can be achieved. By passing a magnetic field in the opposite direction to the electromagnetic coil into the coil of the first magnetic adjustment section 320A, a state in which the two attract each other, i.e., the first luminous state, can be achieved. The embodiments of the present invention are not limited to this in detail.

[0049] Continue to refer Figure 5 and Figure 6 As shown, the light-emitting panel 10 also includes a support column 400 located on one side of the driving substrate 100, the support column 400 includes a support column body 410 and a support surface 420, the support column body 410 extends along the thickness direction of the light-emitting panel 10, and the support surface 420 is located on the side of the support column body 410 away from the driving substrate 100; at least one light-emitting element 200 is located on the side of the support surface 420 away from the support column body 410; the first magnetic adjustment section 320A is located on the side of the support column body 410 close to the driving substrate 100, and the second magnetic adjustment section 320B is located on the side of the first magnetic adjustment section 320A close to the light-emitting element 200; the lampshade 310 also includes a lampshade second end 313, the lampshade second end 313 is sleeved on the support column body 410 and connected to the second magnetic adjustment section 320B.

[0050] Among them, reference Figure 5 and Figure 6 As shown, the light-emitting panel 10 further includes a support column 400, and the support column 400 includes a support column body 410 and a support surface 420, the support surface 420 is located on the side of the support column body 410 away from the driving substrate 100, that is, the support surface 420 is a surface structure of the support column body 410 away from the driving substrate 100, and at least one light-emitting element 200 is arranged on the side of the support surface 420 away from the support column body 410, refer to Figure 5 and Figure 6 The description is made by taking the supporting surface 420 including one light emitting element 200 as an example. In practice, the supporting surface 420 may include a plurality of light emitting elements 200, which is not specifically limited in the embodiment of the present invention.

[0051] Furthermore, the first magnetic adjustment section 320A is located on the side of the support column body 410 close to the driving substrate 100, and the second magnetic adjustment section 320B is located on the side of the first magnetic adjustment section 320A close to the light-emitting element 200, that is, the first magnetic adjustment section 320A and the second magnetic adjustment section 320B are both arranged around the support column body 410, and the support column body 410 extends along the thickness direction of the light-emitting panel 10, and when the first magnetic adjustment section 320A and the second magnetic adjustment section 320B attract or repel each other, they move along the extension direction of the support column body 410.

[0052] Furthermore, the lampshade 310 also includes a second end 313 of the lampshade, and the second end 313 of the lampshade is the end point of the lampshade body 311 close to the driving substrate 100. The second end 313 of the lampshade is sleeved on the support column body 410 and connected to the second magnetic adjustment section 320B, that is, when the first magnetic adjustment section 320A and the second magnetic adjustment section 320B move along the extension direction of the support column body 410 due to attraction or repulsion, the second magnetic adjustment section 320B drives the lampshade 310 to move along the extension direction of the support column body 410 through the second end 313 of the lampshade. In other words, combined with Figure 5 As shown, in the first luminous state, the second magnetic adjustment section 320B and the first magnetic adjustment section 320A are attracted to each other, and the second magnetic adjustment section 320B drives the second end 313 of the lampshade to move along the extension direction of the support column body 410 toward the fixed first magnetic adjustment section 320A; Figure 6 As shown, in the second luminous state, the second magnetic adjustment section 320B repels the first magnetic adjustment section 320A, and the second magnetic adjustment section 320B drives the second end 313 of the lampshade to move away from the fixed first magnetic adjustment section 320A along the extension direction of the support column body 410. That is, the lampshade 310 is fixed by the support column 400 in the first luminous state and the second luminous state, and moves up and down along the thickness direction of the drive substrate 100, thereby realizing different luminous viewing angles of the light-emitting element 200. And in this adjustment mode, the lampshade 320 can only be adjusted up and down in the setting position, without changing the posture of the lampshade 320, and there is no requirement for the deformation degree of the material of the lampshade 320 itself. That is, under the requirement of a larger viewing angle of the light-emitting element 200, that is, in the first luminous state, the lampshade 310 is close to one side of the drive substrate 100, and under the requirement of a smaller viewing angle of the light-emitting element 200, that is, in the second luminous state, which can also be in the anti-peeping state, the lampshade 310 is far away from one side of the drive substrate 100. Different lighting states of the light-emitting panel 10 are achieved, thereby ensuring the lighting effect of the light-emitting panel 10 .

[0053] Continue to refer Figure 7 and Figure 8 As shown, the second magnetic adjustment section 320B is located on a side of the first magnetic adjustment section 320A close to the lampshade 310 , and the second magnetic adjustment section 320B is connected to the side wall 310A of the lampshade 310 .

[0054] Furthermore, the lampshade 310 also includes a side wall 310A, which is a contact surface of the lampshade body 311 for contacting the second magnetic adjustment section 320B. The side wall 310A of the lampshade 310 is connected to the second magnetic adjustment section 320B, that is, the movement of the second magnetic adjustment section 320B due to the repulsion and attraction with the first magnetic adjustment section 310A can drive the side wall 310A to deflect at different angles, thereby adjusting the position of the lampshade 310, and further achieving different light output angles of the light-emitting element 200.

[0055] Further, combined with Figure 7 As shown, in the first light-emitting state, the second magnetic adjustment section 320B and the first magnetic adjustment section 320A are attracted to each other, so that the second magnetic adjustment section 320B moves closer to the first magnetic adjustment section 320A, thereby driving the side wall 310A of the lampshade 310 to move closer to the first magnetic field adjustment section 320A, thereby achieving the first end 312 of the lampshade 310 close to the side of the driving substrate 100, that is, achieving a larger light output angle of the light-emitting element 200. Figure 8 As shown, in the second luminous state, through the state of repulsion between the second magnetic adjustment section 320B and the first magnetic adjustment section 320A, the second magnetic adjustment section 320B moves away from the first magnetic adjustment section 320A, thereby driving the side wall 310A of the lampshade 310 to move away from the first magnetic field adjustment section 320A, thereby realizing that the first end 312 of the lampshade 310 is away from the driving substrate 100, that is, realizing a smaller light output angle of the light-emitting element 200, and realizing the anti-peeping mode of the light-emitting panel 10. That is, the posture adjustment unit 320 provided in the embodiment of the present invention moves left and right along the horizontal direction of the driving substrate 100 in the first luminous state and the second luminous state, thereby realizing different luminous angles of the light-emitting element 200. And in this adjustment mode, the lampshade 320 can only adjust the position of one end of the lampshade 320, without a large position change of the lampshade 320, while enriching the position adjustment mode of the lampshade 320, and realizing different luminous angles of the light-emitting element 200 in a smaller adjustment mode. That is, when the light emitting element 200 has a larger viewing angle, that is, in the first light-emitting state, the side wall 310A of the lampshade 310 is away from the light emitting element 200, and when the light emitting element 200 has a smaller viewing angle, that is, in the second light-emitting state or in the anti-peeping state, the side wall 310A of the lampshade 310 is close to the light emitting element 200. Different light-emitting states of the light-emitting panel 10 are achieved, thereby ensuring the light-emitting effect of the light-emitting panel 10.

[0056] Fig.11 for Figure 1 Another cross-sectional diagram along the A-A' direction, Fig.12 for Figure 1 Another cross-sectional diagram along the A-A' direction, see Fig.11 and Fig.12 As shown, the side wall 310A of the lampshade body 311 includes a flat surface or a curved surface.

[0057] Specifically, the shape of the side wall 310A of the lampshade body 311 is diverse, for example, refer to Fig.11 As shown, the side wall 310A of the lampshade 310 may be a plane. Fig.12 As shown, the side wall 310A of the lampshade 310 may also be a curved surface. By providing a variety of shapes for the side wall 310A, the lampshade 310 may be provided in a variety of ways, thereby satisfying different types of light-emitting panels 10 .

[0058] Fig.13 for Fig.12 An enlarged schematic diagram of the B area, see Fig.12 and Fig.13 As shown, the side wall 310A of the lampshade body 311 includes a first reflection position c1 and a second reflection position c2, the first reflection position c1 is located on the side of the second reflection position c2 close to the driving substrate 100, and in the multiple lampshades 310 surrounding the light-emitting element 200, the first reflection position c1 is located on the side of the second reflection position c2 close to the light-emitting element 200; the angle between the tangent at the first reflection position c1 and the plane where the driving substrate 100 is located is θ1, and the angle between the tangent at the second reflection position c2 and the plane where the driving substrate 100 is located is θ2, wherein 0°<θ1<θ2≤90°.

[0059] Specifically, the side wall 310A includes a first reflection position c1 and a second reflection position c2. The first reflection position c1 is closer to the drive substrate 100 and the light emitting element 200 than the second reflection position c2. Further, the angle θ1 between the tangent line at the first reflection position c1 and the plane where the drive substrate 100 is located and the angle θ2 between the tangent line at the second reflection position c2 and the plane where the drive substrate 100 is located satisfy 0°<θ1<θ2≤90°, that is, the following is formed: Fig.13 The side wall 310A of the lampshade body 311 is shown in the figure. The solution in the embodiment of the present invention can allow more light emitted by the light-emitting element 200 to be emitted from the lampshade 310. In the second light-emitting state, that is, the anti-peeping mode, the light-emitting viewing angle of the light-emitting element 200 can be reduced to ensure the anti-peeping effect of the light-emitting panel 10.

[0060] It should be noted that the figure only takes one connection method between the lampshade 310 and the posture adjustment unit 320 as an example, and other connection methods between the lampshade 310 and the posture adjustment unit 320 also satisfy the above relationship, and the embodiment of the present invention does not make specific limitations on this.

[0061] Continue to refer Fig. 9 and Fig.10As shown, the posture adjustment unit 320 includes a first magnetic adjustment section 320A and a second magnetic adjustment section 320B; the first magnetic adjustment section 320A is fixedly arranged; the second magnetic adjustment section 320B is used to connect with the lampshade 310 and the second magnetic adjustment section 320B is movably arranged; in the first luminous state, the magnetic field directions in the first magnetic adjustment section 320A and the second magnetic adjustment section 320B are the same, and in the second luminous state, the magnetic field directions in the first magnetic adjustment section 320A and the second magnetic adjustment section 320B are opposite.

[0062] Among them, the posture adjustment unit 320 includes a first magnetic adjustment section 320A and a second magnetic adjustment section 320B. By adjusting the direction of the magnetic field input between the first magnetic adjustment section 320A and the second magnetic adjustment section 320B, two situations are achieved: the first magnetic adjustment section 320A and the second magnetic adjustment section 320B have the same magnetic field direction and the second magnetic adjustment section 320B have different magnetic field directions. Specifically, when the magnetic field directions in the first magnetic adjustment section 320A and the second magnetic adjustment section 320B are opposite, the first magnetic adjustment section 320A and the second magnetic adjustment section 320B are in an attractive state, and when the magnetic field directions in the first magnetic adjustment section 320A and the second magnetic adjustment section 320B are the same, the first magnetic adjustment section 320A and the second magnetic adjustment section 320B are in a repulsive state. And the positional relationship between the first magnetic adjustment section 320A and the second magnetic adjustment section 320B is adjusted by the repulsion or attraction between the first magnetic adjustment section 320A and the second magnetic adjustment section 320B, thereby driving the lampshade 310 to move to achieve different light emitting angles of the light emitting element 200, that is, to achieve different light emitting states of the light emitting panel 10, thereby ensuring the light emitting effect of the light emitting panel 10. The lampshade 320 adjusts the position through the direction of the magnetic magnetic field, that is, the adjustment of the position of the lampshade 320 and the light emitting element 200 is simple, easy to achieve, and cost-controlled.

[0063] Exemplary, reference Fig. 9 As shown, in the first luminous state, the magnetic field directions of the first magnetic adjustment section 320A and the second magnetic adjustment section 320B are the same, and when the first magnetic adjustment section 320A is fixed, the second magnetic adjustment section 320B moves away from the first magnetic adjustment section 320B, thereby driving the lampshade 310 to achieve the first posture state. Fig.10 As shown, in the second luminous state, the directions of the magnetic fields in the first magnetic adjustment section 320A and the second magnetic adjustment section 320B are opposite, and when the first magnetic adjustment section 320A is fixed, the second magnetic adjustment section 320B fits against the first magnetic adjustment section 320B, thereby driving the lampshade 310 to achieve the second posture state.

[0064] Continue to refer Fig. 9 and Fig.10 As shown, the lampshade 310 includes a plurality of sub-lampshades 330 connected to each other, the plurality of sub-lampshades 330 are arranged along a first direction X, and the sizes of the sub-lampshades 330 in the first direction X and the second direction Y are adjustable; the first direction X is parallel to the direction in which the first magnetic adjustment section 320A points to the second magnetic adjustment section 320B, and the second direction Y is parallel to the thickness direction of the light-emitting panel 10; among the plurality of sub-lampshades 330 surrounding the light-emitting element 200, the sub-lampshade 330 on the side away from the light-emitting element 200 is connected to the second magnetic adjustment section 320B; in the first light-emitting state, the size of the sub-lampshade 330 in the first direction X is greater than the size of the sub-lampshade 330 in the second light-emitting state, and the size of the sub-lampshade 330 in the first light-emitting state in the second direction Y is smaller than the size of the sub-lampshade 330 in the second light-emitting state in the second direction Y.

[0065] Specifically, the lampshade 310 includes a plurality of sub-lampshades 330, and the plurality of sub-lampshades 330 are arranged along a first direction and connected to each other. Fig. 9 and Fig.10 In the description, an example is given in which the lampshade 310 includes three sub-lampshades 330 . The embodiment of the present invention does not specifically limit the number of the sub-lampshades 330 .

[0066] Furthermore, the dimensions of the sub-lamp cover 330 in the first direction X and the second direction Y can be adjusted. For example, Fig. 9 The size of the neutron lampshade 330 in the first direction X is larger than Fig.10 The size of the neutron lampshade 330 in the first direction X is: Fig. 9 The size of the neutron lampshade 330 in the second direction Y is smaller than Fig.10 The size of the sub-lampshade 330 in the second direction Y, that is, the sub-lampshade 330 can be adjusted in multiple directions so that the lampshade 310 can also be adjusted in multiple directions, thereby achieving different shapes of the lampshade 310 under different lighting states of the light-emitting panel 10.

[0067] Specifically, the lampshade 310 surrounds at least one light emitting element 200, that is, the plurality of sub-lampshades 330 surround at least one light emitting element 200. Fig. 9 and Fig.10 In the example of setting a light emitting element 200 in the surrounding area, a sub-lampshade 330 far away from the light emitting element 200 in the surrounding area is connected to the second magnetic field adjustment sub-section 320B, that is, when the second magnetic adjustment sub-section 320B moves toward or away from the first magnetic adjustment sub-section 320A, the sub-lampshade 330 connected thereto is driven to move together. Fig. 9As shown, in the first light-emitting state, the magnetic field direction of the second magnetic adjustment section 320B is the same as that of the first magnetic adjustment section 320A, that is, the second magnetic adjustment section 320B and the first magnetic adjustment section 320A are in a repulsive state, driving the sub-lampshade 330 connected thereto to move away from the light-emitting element 200, while the sub-lampshade 330 close to the light-emitting element 200 is fixed, and the lampshade 310 formed by the multiple sub-lampshades 330 extends along the first direction X, and at the same time, the multiple sub-lampshades 330 are compressed along the second direction Y, or it can be said that the sub-lampshade 330 becomes longer along the first direction X and shorter along the second direction Y while the area remains unchanged, that is, the first end 312 of the lampshade moves toward the side close to the drive substrate 100, and the viewing angle of the light-emitting element 200 is larger. Reference Fig.10 As shown, in the second light-emitting state, the magnetic field directions of the second magnetic adjustment section 320B and the first magnetic adjustment section 320A are opposite, that is, the second magnetic adjustment section 320B and the first magnetic adjustment section 320A are in an attracting state, driving the sub-lampshade 330 connected thereto to move toward the side close to the light-emitting element 200, while the sub-lampshade 330 close to the side of the light-emitting element 200 is fixed, then the lampshade 310 formed by the multiple sub-lampshades 330 is compressed along the first direction X, and at the same time, the multiple sub-lampshades 330 are stretched along the second direction Y, or it can be said that the sub-lampshade 330 becomes shorter along the first direction X and longer along the second direction Y while the area remains unchanged, that is, the first end 312 of the lampshade moves toward the side away from the driving substrate 100, and the viewing angle of the light-emitting element 200 is small. The lampshade 310 formed by connecting the multiple sub-lampshades 330 is further realized in a flexible setting mode of the lampshade 310. That is, when the structure of the sub-lampshade 330 can be compressed or stretched, the position of the lampshade 310 can be adjusted by combining the position adjustment of the first magnetic adjustment section 320A between the second magnetic adjustment sections 320B, thereby achieving different light output angles of the light-emitting element 200 and ensuring the light-emitting effect of the light-emitting panel 10.

[0068] Continue to refer Fig. 9 and Fig.10 As shown, the cross-sectional shape of the sub-lamp cover 330 includes an ellipse or a polygon.

[0069] Furthermore, the cross-sectional shape of the sub-lamp cover 330 is diverse, for example Fig. 9 and Fig.10 As shown, the cross-sectional shape of the sub-lampshade 330 can be a quadrilateral. In different light-emitting states, the sub-lampshade 330 is compressed and stretched in different directions to achieve different postures between the lampshade 310 and the light-emitting element 200. Furthermore, the cross-sectional shape of the sub-lampshade 330 can also be an ellipse, a pentagon, or a hexagon, etc., and the embodiments of the present invention are not specifically limited to this.

[0070] Fig.14 for Figure 1Another cross-sectional diagram along the A-A' direction, see Fig.14 As shown, along the second direction Y, the distance between the vertical projection of the first end 312 of the lampshade and the vertical projection of the light-emitting element 200 is t; along the second direction Y, the intersection of the vertical projection of the light-emitting element 200 and the driving substrate 100 is the first point n; in the first light-emitting state, in the lampshade 310 surrounding the light-emitting element 200, the angle between the direction in which the first point n extends to the first end 312 of the lampshade and the driving substrate 100 is a1, and in the second light-emitting state, in the lampshade 310 surrounding the light-emitting element 200, the angle between the direction in which the first point n extends to the first end 312 of the lampshade and the driving substrate 100 is a2, wherein, (L2-L1)=t*(tan(a2)-tan(a1)); the second direction Y is the thickness direction of the light-emitting panel 10.

[0071] Specifically, refer to Fig.14 As shown, Fig.14 The lampshade 310 (m1) in the solid line is the lampshade 310 in the first light-emitting state. Fig.14 The lampshade 310 (m2) in the middle dashed line is the lampshade 310 in the second light-emitting state. By placing the lampshade 310 in the first light-emitting state and the second light-emitting state in the same figure, the change of the first end 312 of the lampshade can be intuitively seen.

[0072] Exemplary, reference Fig.14 As shown, the distance between the vertical projection of the first end 312 of the lampshade and the vertical projection of the light-emitting element 200 is t, and the intersection of the vertical projection of the light-emitting element 200 and the driving substrate 100 is the first point n. When the angle between the direction in which the first point n extends to the first end 312 of the lampshade and the driving substrate 100 is a1, the light-emitting angle of the light-emitting element 200 is larger, and the light-emitting panel 10 is in the first light-emitting state; when the angle between the direction in which the first point n extends to the first end 312 of the lampshade and the driving substrate 100 is a2, the light-emitting angle of the light-emitting element 200 is smaller, and the light-emitting panel 10 is in the second light-emitting state, i.e., the anti-peeping state. And the degree of position adjustment of the first end 312 of the lampshade in the two states is: (L2-L1)=t*(tan(a2)-tan(a1)). It should be noted that, Fig.14 Only one connection method between the lampshade 310 and the posture adjustment unit 320 is taken as an example. Other connection methods between the lampshade 310 and the posture adjustment unit 320 also satisfy the above relationship, and the embodiment of the present invention does not make specific limitations on this.

[0073] Fig.15 for Figure 1 Another cross-sectional diagram along the A-A' direction, see Fig.15 As shown, an anti-reflection film 500 is disposed on the surface of the lampshade 310 close to the light emitting element 200 .

[0074] The light-emitting panel 10 may further include an anti-reflection film 500, and the anti-reflection film 500 is located on the side of the lampshade 310 close to the light-emitting element 200. The anti-reflection film 500 can prevent the internal light of the light-emitting element 200 from reflecting and causing a larger viewing angle of the light-emitting element 200, thereby ensuring the light-emitting effect of the light-emitting panel 10 in the second light-emitting state, i.e., the anti-peeping state, and further ensuring the overall light-emitting effect of the light-emitting panel 10.

[0075] refer to Figures 1 to 15 As shown, the light emitting element 200 comprises a micro light emitting diode or a mini light emitting diode.

[0076] Furthermore, the light-emitting element 200 included in the light-emitting panel 10 can be a micro light-emitting diode or a mini light-emitting diode. The light-emitting panel 10 using a micro light-emitting diode or a mini light-emitting diode has many advantages such as self-luminescence, low driving voltage, high luminous efficiency, short response time, high clarity and contrast. In addition, since the micro light-emitting diode or the mini light-emitting diode is small in size, by setting the light-emitting element 200 to include a micro light-emitting diode or a mini light-emitting diode, more light-emitting elements can be set in the same light-emitting area, thereby improving the light-emitting resolution of the light-emitting panel. Exemplarily, the size of the mini light-emitting diode is between 100 microns and 500 microns, and the size of the micro light-emitting diode can be less than 100 microns, which is not specifically limited in the embodiment of the present invention.
