Description

Technical Field

[0001] The present application belongs to the technical field of light-emitting modules, and in particular relates to a light-emitting module and a display device. Background Art

[0002] In some special occasions, there is a need for double-sided display and anti-peeping. For example, bank staff can provide the anti-peeping display surface to customers when handling business, and the teller can switch the anti-peeping display surface to themselves when there is a need for anti-peeping. For another example, in public places, double-sided display advertising machines face the outdoor display surface, which will reflect glare when viewed by customers and require a small viewing angle for viewing, that is, the anti-peeping display surface is provided to customers. However, the light-emitting modules of the related art usually cannot adjust the anti-peeping display surface at will, and cannot meet the use requirements of the light-emitting modules in special occasions. Summary of the invention

[0043] The present embodiment provides a light-emitting module 1, which includes a light-emitting component 11, and a first light-emitting surface 12 and a second light-emitting surface 13 arranged on opposite sides of the light-emitting component 11, the light-emitting component 11 includes a substrate 111, a first light-emitting unit 112 and a second light-emitting unit 113 arranged on opposite sides of the substrate 111, the light emitted by the first light-emitting unit 112 has a first light-emitting angle, the light emitted by the second light-emitting unit 113 has a second light-emitting angle, and the first light-emitting angle is greater than the second light-emitting angle.

[0044] The substrate 111 can rotate relative to the first light-emitting surface 12 so that the light emitted by the first light-emitting unit 112 is emitted from one of the first light-emitting surface 12 and the second light-emitting surface 13, and the light emitted by the second light-emitting unit 113 is emitted from the other of the first light-emitting surface 12 and the second light-emitting surface 13.

[0045] The light emitting module 1 provided in this embodiment may include other components in addition to the light emitting component 11, the first light emitting surface 12, and the second light emitting surface 13. Optionally, the light emitting module 1 also includes a housing 14 having a cavity, a first optical component 15, a second optical component 16, a first light emitting component having a first light emitting surface 12, and a second light emitting component having a second light emitting surface 13. The housing 14 also includes a first opening connected to the cavity and a second opening connected to the cavity, and the first opening and the second opening are arranged opposite to each other. The first light emitting component is arranged at the first opening and fixed to the housing 14, and the second light emitting component is arranged at the second opening and fixed to the housing 14. The light emitting component 11, the first optical component 15, and the second optical component 16 are all arranged in the cavity. The first optical component 15 is arranged between the first light emitting component and the light emitting component 11. The second optical component 16 is arranged between the second light emitting component and the light emitting component 11. Further optionally, the first optical component 15 and the second optical component 16 each include at least one functional film. For example, the functional film may be a color filter film, an anti-reflection film, a protective film, or the like.

[0046] The light emitting module 1 provided in this embodiment includes a first light emitting surface 12 and a second light emitting surface 13. The first light emitting surface 12 and the second light emitting surface 13 can allow light from the first light emitting unit 112 or the second light emitting unit 113 to pass through. This embodiment does not limit the specific structure of the first light emitting surface 12 and the second light emitting surface 13. In other words, the light of the light emitting component 11 can be emitted from the first light emitting surface 12 and the second light emitting surface 13.

[0047] Optionally, the first light emitting component includes a first light emitting surface 12 and a light receiving surface facing each other, and the second light emitting component includes a second light emitting surface 13 and a light receiving surface facing each other, and the light receiving surface of the first light emitting component faces the light receiving surface of the second light emitting component.

[0048] The light emitting assembly 11 provided in this embodiment includes a substrate 111, a first light emitting unit 112, and a second light emitting unit 113. There are multiple first light emitting units 112, and the multiple first light emitting units 112 are arranged in an array on one side of the substrate 111. There are multiple second light emitting units 113, and the multiple second light emitting units 113 are arranged in an array on the other side of the substrate 111.

[0049] Optionally, the light emitting assembly 11 further includes a rotating member 114 and a track 115. The rotating member 114 is disposed on one side of the substrate 111, the rotating member 114 is mounted on the track 115, and the rotating member 114 is rotatably connected to the track 115. The rotating member 114 can drive the substrate 111 to rotate relative to the track 115. The extension of the track 115 is perpendicular to the first light emitting surface 12 and points to the arrangement direction of the second light emitting surface 13. For example, by controlling the rotating member 114, the rotating member 114 is rotated relative to the first light emitting surface 12, thereby driving the substrate 111 to rotate relative to the first light emitting surface 12. For another example, by controlling the track 115, the track 115 drives the rotating member 114 to rotate, and then the rotating member 114 drives the substrate 111 to rotate relative to the first light emitting surface 12.

[0050] Further optionally, at least part of the rotating member 114 is provided with a track 115. Further optionally, the rotating member 114 can be a gear, or a rotating shaft, etc. The track 115 can be an inner gear ring, or a rotating shaft, or a belt, etc.

[0051] Optionally, the light emitting assembly 11 further includes a motor, and the motor is rotatably connected to the rotating member 114 to drive the rotating member 114 , or the motor is rotatably connected to the track 115 to drive the track 115 .

[0052] The light emitting module 1 has a first state and a second state. The substrate 111 of the light emitting component 11 can rotate so that the light emitting module 1 switches between the first state and the second state. The rotation direction of the substrate 111 is as follows: Figure 5 When the light emitting module 1 is in the first state, the light of the first light emitting unit 112 is emitted from the first light emitting surface 12, and the light of the second light emitting unit 113 is emitted from the second light emitting surface 13. When the light emitting module 1 is in the second state, the light of the first light emitting unit 112 is emitted from the second light emitting surface 13, and the light of the second light emitting unit 113 is emitted from the first light emitting surface 12.

[0053] When the light emitting module 1 is in the first state, the first light emitting unit 112 faces the first light emitting surface 12, and the second light emitting unit 113 faces the second light emitting surface 13; when the light emitting module 1 is in the second state, the first light emitting unit 112 faces the second light emitting surface 13, and the second light emitting unit 113 faces the first light emitting surface 12.

[0054] Furthermore, since the first light emitting angle is greater than the second light emitting angle, the light emitting surface emitted by the first light emitting unit 112 is a wide-viewing, normal-displaying light emitting surface; the light emitting surface emitted by the second light emitting unit 113 is a narrow-viewing, anti-peeping light emitting surface. Therefore, when the light emitting module 1 is in the first state, the first light emitting surface 12 is a normal-displaying surface, and the second light emitting surface 13 is an anti-peeping display surface; when the light emitting module 1 is in the second state, the first light emitting surface 12 is an anti-peeping display surface, and the second light emitting surface 13 is a normal-displaying surface.

[0055] Optionally, the first light output angle (such as Figure 2 The middle angle α is 100°-140°. Specifically, the first light output angle can be 100°, or 110°, or 120°, or 130°, or 140°, etc.

[0056] Optionally, the second light output angle (such as Figure 2 The middle angle β is 50°-90°. Specifically, the first light output angle can be 50°, 60°, 70°, 80°, 90°, etc.

[0057] Therefore, this embodiment provides a rotatable substrate 111 in the light-emitting component 11 to change the light-emitting surfaces of the first light-emitting unit 112 and the second light-emitting unit 113, so that the light-emitting module 1 can adjust the two light-emitting surfaces between the normal display surface and the anti-peeping display surface according to user or product requirements, thereby meeting the use requirements of the light-emitting module 1 in special occasions and broadening the scope of application of the light-emitting module 1.

[0058] In summary, the light-emitting module 1 provided in this embodiment has a first light-emitting surface 12 and a second light-emitting surface 13, and can control the rotation of the substrate 111, control the flipping of the first light-emitting unit 112 and the second light-emitting unit 113, and freely switch the normal display surface and the anti-peeping display surface between the two light-emitting surfaces, so as to achieve the effect that any one light-emitting surface is in the normal display surface and the other light-emitting surface is in the anti-peeping display surface.

[0059] Please refer to Figure 1-Figure 5 In one embodiment, the substrate 111 includes a plurality of sub-boards 1111 arranged along an arrangement direction perpendicular to the first light emitting surface 12 and the second light emitting surface 13, the first light emitting unit 112 and the second light emitting unit 113 are arranged on opposite sides of each of the sub-boards 1111, and each of the sub-boards 1111 can rotate relative to the first light emitting surface 12.

[0060] The light-emitting module 1 provided in this embodiment includes a sub-board 1111. A plurality of first light-emitting units 112 are arranged at intervals on one side of the sub-board 1111 along the extension direction of the sub-board 1111, and the arrangement direction of the first light-emitting units 112 of each sub-board 1111 is the same. For example, a sub-board 1111 is provided with a column of first light-emitting units 112. For another example, a sub-board 1111 is provided with multiple columns of first light-emitting units 112. A plurality of second light-emitting units 113 are arranged at intervals on one side of the sub-board 1111 along the extension direction of the sub-board 1111, and the arrangement direction of the second light-emitting units 113 of each sub-board 1111 is the same. For example, a sub-board 1111 is provided with a column of second light-emitting units 113. For another example, a sub-board 1111 is provided with multiple columns of second light-emitting units 113. Optionally, the rotating member 114 is disposed on two opposite sides of each sub-plate 1111 , and the rotating member 114 is rotatably connected to the track 115 . The rotating member 114 can drive the sub-plate 1111 to rotate relative to the track 115 .

[0061] For example, all sub-panels 1111 may be controlled to rotate in the same direction, so that the entire first light emitting surface 12 and the entire second light emitting surface 13 can be adjusted between the normal display surface and the anti-peeping display surface. For another example, some sub-panels 1111 may be controlled to rotate in the same direction, while other sub-panels 1111 cannot, so that part of the first light emitting surface 12 and part of the second light emitting surface 13 can be adjusted between the normal display surface and the anti-peeping display surface.

[0062] In this embodiment, the substrate 111 is split into a plurality of sub-boards 1111, and each sub-board 1111 is provided with a first light-emitting unit 112 and a second light-emitting unit 113, so that the first light-emitting surface 12 and the second light-emitting surface 13 can be adjusted in whole or in part according to the needs of the user or the product, so that the first light-emitting surface 12 and the second light-emitting surface 13 can be switched between the normal display surface and the anti-peeping display surface, so as to meet the use requirements of the light-emitting module 1 in special occasions and further broaden the application scope of the light-emitting module 1. In addition, in this embodiment, the substrate 111 is split into a plurality of sub-boards 1111, so that the situation that the entire substrate 111 cannot rotate due to damage of a rotating member 114 is avoided, thereby improving the reliability of the light-emitting module 1.

[0063] Please refer to Figure 1-Figure 6 , Figure 6 A schematic diagram of the structure of the second light-emitting unit provided in one embodiment of the present application Figure 1 In one embodiment, the second light-emitting unit 113 includes a light-emitting member 1131 disposed on the sub-board 1111, a light-controlling member 1132 disposed around the light-emitting member 1131, and an elastic member 1133 disposed between the sub-board 1111 and the light-controlling member 1132, wherein the light-controlling member 1132 is used to limit the light emission angle of the light emitted by the light-emitting member 1131.

[0064] The second light-emitting unit 113 provided in this embodiment includes a light-emitting component 1131 and a light-control component 1132. The light-emitting component 1131 is used to emit light. Optionally, the light-emitting component 1131 may be a lamp bead, an organic light-emitting diode, etc. The light-control component 1132 is used to limit the light emission angle of the light emitted by the light-emitting component 1131. For example, the normal light emission angle of the light emitted by the light-emitting component 1131 is 120°. The light from the light-emitting component 1131 passes through the light-control component 1132, so that the light emission angle becomes 90°, so that the second light emission angle of the second light-emitting unit 113 is 90°. The second light emission angle refers to the light emission angle of the light from the light-emitting component 1131 after passing through the light-control component 1132. The light emitted by the second light-emitting unit 113 is as follows: Figure 6 As shown in L1.

[0065] Optionally, the first light emitting unit 112 includes a light emitting member 1131. The light emitting member 1131 is used to emit light. Optionally, the light emitting member 1131 may be a lamp bead, an organic light emitting diode, etc. For example, the first light emitting unit 112 is not provided with a light control member 1132. In this case, the first light emitting angle is the light emitting angle of the light from the light emitting member 1131, so the first light emitting angle is greater than the second light emitting angle.

[0066] The second light-emitting unit 113 provided in this embodiment also includes an elastic member 1133, which is used for buffering to prevent the light control member 1132 from being damaged. The elastic member 1133 is elastic. One end of the elastic member 1133 abuts against the sub-plate 1111, and the other end abuts against the light control member 1132. Optionally, a plurality of elastic members 1133 are arranged at intervals along the circumferential direction of the light-emitting member 1131. Optionally, one side of the elastic member 1133 is fixed to the sub-plate 1111, and the light-emitting member 1131 and the light control member 1132 are both arranged on the surface of the back ion plate 1111 of the elastic member 1133.
