It is to be understood that the described embodiments are merely exemplary of the invention, and not restrictive of the full scope of the invention. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.
The technical solutions disclosed in the embodiments of the present invention are described in detail below with reference to the accompanying drawings.
As shown in fig. 1 to 4, an embodiment of the present invention discloses a display module, which can be applied to an electronic device and specifically includes a cover plate 100, an optical path adjusting portion 200, and a light emitting portion 500. The cover plate 100 may be light-transmissive, and the cover plate 100 may be specifically a glass plate. The light emitting part 500 may emit light, and the light emitting part 500 may be a backlight, in which case the display module may be a liquid crystal display module; alternatively, the light emitting part 500 may be an organic light emitting layer, and in this case, the display module may be an organic light emitting display module. The optical path adjusting part 200 is located between the cover plate 100 and the light emitting part 500, and the light emitted from the light emitting part 500 can pass through the optical path adjusting part 200, then be emitted from the cover plate 100, and finally reach the lens 610 of the user's eyeball 600, as shown by the arrow line in fig. 1.
Specifically, the optical path adjusting portion 200 may include a frame 210, and a plurality of first plates 220 and a plurality of second plates 230 disposed on the frame 210, where the frame 210 may surround the plurality of first plates 220 and the plurality of second plates 230, and may have a rectangular shape. The plurality of first plates 220 are arranged at intervals, the plurality of second plates 230 are arranged at intervals, and at least one of the first plates 220 and the second plates 230 is rotatably connected to the frame 210, so that the angle of at least one of the first plates 220 and the second plates 230 relative to the frame 210 can be adjusted. In addition, only a part of the first plates 220 of the plurality of first plates 220 may be rotatably connected to the frame 210, another part of the first plates 220 may be fixed to the frame 210, or all of the first plates 220 may be rotatably connected to the frame 210. The angles of the first plates 220 rotatably coupled to the frame 210 with respect to the frame 210 may be adjusted individually or simultaneously. Similarly, only a portion of the second plates 230 of the plurality of second plates 230 may be rotatably connected to the frame 210, another portion of the second plates 230 may be fixed with respect to the frame 210, or all of the second plates 230 may be rotatably connected to the frame 210. The angles of the second plates 230 rotatably coupled to the frame 210 with respect to the frame 210 may be adjusted individually or simultaneously. In a direction perpendicular to the cover plate 100, the first plate 220 and the second plate 230 are stacked, and projections of the first plate 220 and the second plate 230 intersect. At this time, the plurality of first plates 220 and the plurality of second plates 230 are combined to form a channel having a predetermined shape, and of the light emitted from the light emitting unit 500, only the light parallel to the channel may pass through the channel and reach the cover plate 100, and the rest of the light is absorbed by the light path adjusting unit 200.
The light path adjusting portion 200 can adjust the emitting direction of the light, so that only the light (e.g., the parallel light shown by the dashed-dotted line in fig. 1) parallel to the first plate 220 and the second plate 230 can be emitted, and at least one of the first plate 220 and the second plate 230 is rotatably connected to the frame 210, so that the direction of the light emitted by the display module can be adjusted to simulate the situation that the user alternately watches the long-distance view and the short-distance view, and prevent the ciliary muscle from being in the contraction state for a long time, thereby reducing the risk of the user's short-sightedness. Therefore, the display module has smaller threat to the health of the user. In addition, the structure can also expand the display form of the display module, for example, the convergence of the display range, the light path shielding, the change of the directional display direction, the enhancement of the directional display and other forms can be realized, that is, the user can see the content displayed by the display module from one or more specific directions, so that the application scene of the display module is more diversified.
Alternatively, in order to simplify the structure of the display module, the first board 220 and the second board 230 may be configured as flat boards, the plurality of first boards 220 are parallel to each other, and the plurality of second boards 230 are parallel to each other. Further, first plate body 220 and second plate body 230 can mutually perpendicular, and at this moment, a plurality of first plate bodies 220 and a plurality of second plate body 230 can form the passageway of rectangle jointly to make the light that the whole display area of display module jetted out more even, thereby improve the display effect of display module.
In order to adjust the angles of the first plate 220 and the second plate 230 with respect to the frame 210 more accurately, the display module may further include a first driving mechanism 301 and a second driving mechanism 302 disposed on the frame 210, wherein: the first driving mechanism 301 is connected to the first board 220, so that the first driving mechanism 301 can drive the first board 220 to rotate relative to the frame 210; the second driving mechanism 302 is connected to the second plate 230, so that the second driving mechanism 302 can drive the second plate 230 to rotate relative to the frame 210. The first driving mechanism 301 and the second driving mechanism 302 may receive a control signal, so as to drive the first board 220 and the second board 230 to rotate by a preset angle according to the control signal, thereby obtaining a predetermined display effect.
In order to simplify the structure of first driving mechanism 301, as shown in fig. 4, first driving mechanism 301 may include a first magnetic member 310 and a second magnetic member 320, first magnetic member 310 is connected to first board 220, and first magnetic member 310 drives first board 220 to rotate when first magnetic member 310 interacts with second magnetic member 320. Specifically, when the magnetic field directions of the first magnetic member 310 and the second magnetic member 320 are the same, a repulsive force may be generated therebetween, so that the first magnetic member 310 moves under the action of the repulsive force and drives the first plate 220 to rotate; when the magnetic fields of the first magnetic member 310 and the second magnetic member 320 are opposite in direction, an attraction force may be generated therebetween, so that the first magnetic member 310 moves under the action of the attraction force and may drive the first plate 220 to rotate. Since the first and second magnetic members 310 and 320 have a relatively simple structure and occupy a smaller space, the structure can reduce the space occupied by the first driving mechanism 301 in addition to simplifying the structure of the first driving mechanism 301.
Similarly, the second driving mechanism 302 may include a third magnetic member and a fourth magnetic member, the third magnetic member is connected to the second plate 230, and when the third magnetic member and the fourth magnetic member act, the third magnetic member drives the second plate 230 to rotate. The second driving mechanism 302 is relatively simple in structure and occupies a smaller space.
In an alternative embodiment, the first plate 220 may be connected to the frame 210 through the first rotating shaft 400, and specifically, the first rotating shaft 400 may be fixed to the first plate 220 and connected to the frame 210 in a rotating manner; alternatively, the first shaft 400 may be rotatably connected to the first plate 220 and fixed to the frame 210. When the first rotating shaft 400 is rotatably connected to the first plate 220 and is fixed to the frame 210, the first magnetic member 310 may be directly connected to the first plate 220, for example, the first magnetic member 310 may be directly disposed on the first plate 220, so as to drive the first plate 220 to rotate. When the first rotating shaft 400 is fixed to the first plate 220 and is rotatably connected to the frame 210, the first magnetic member 310 may include a first coil wound around the first rotating shaft 400, and the second magnetic member 320 is a permanent magnet. That is, the first magnetic member 310 may be an electromagnet, and when the first coil is energized with current, a magnetic field is generated around the first coil, and the magnetic field interacts with the magnetic field of the second magnetic member 320, so that a force is generated between the first magnetic member 310 and the second magnetic member 320 to drive the first plate 220 to rotate. Meanwhile, by changing the magnitude of the current flowing into the first coil, the magnitude of the acting force between the first magnetic member 310 and the second magnetic member 320 can be adjusted, so that the rotation angle of the first plate 220 can be adjusted more flexibly.
Similarly, the second plate 230 may be connected to the frame 210 through a second rotating shaft, specifically, the second rotating shaft may be fixed to the second plate 230 and simultaneously rotatably connected to the frame 210; alternatively, the second shaft may be rotatably connected to the second plate 230 and fixed to the frame 210. The third magnetic member may include a second coil wound around the second rotating shaft, and the fourth magnetic member may be a permanent magnet. The magnitude of the acting force between the third magnetic member and the fourth magnetic member can be adjusted by changing the magnitude of the current passing through the second coil, so that the rotation angle of the second plate 230 can be adjusted more flexibly.
As mentioned above, the second magnetic member 320 may be a permanent magnet, the second magnetic member 320 includes a first magnetic pole 321 and a second magnetic pole 322, the first magnetic pole 321 and the second magnetic pole 322 are arranged at intervals, and the first coil is located between the first magnetic pole 321 and the second magnetic pole 322. At this time, the first coil is substantially completely located in the magnetic field of the second magnetic member 320, and when the first coil is energized, the magnetic field generated by the first coil is closer to the magnetic field of the second magnetic member 320, and the acting force generated between the first coil and the second magnetic member is larger, so as to drive the first plate 220 to rotate more effectively.
Similarly, the fourth magnetic member may include a third magnetic pole and a fourth magnetic pole, the third magnetic pole and the fourth magnetic pole are arranged at intervals, and the second coil is located between the third magnetic pole and the fourth magnetic pole. At this time, the second coil is substantially completely located in the magnetic field of the fourth magnetic member, and when the second coil is energized, the magnetic field generated by the second coil is closer to the magnetic field of the fourth magnetic member, and the acting force generated between the second coil and the magnetic field of the fourth magnetic member is larger, so that the second plate 230 is driven to rotate more effectively.
Because the number of the first plate bodies 220 is multiple, when the structure is specifically designed, only one of the first plate bodies 220 may be connected with the first coil, so that the first coil only drives the first plate body 220 to rotate, and the first plate body 220 may be connected with other first plate bodies 220 through an additionally arranged linkage structure, thereby realizing driving of the plurality of first plate bodies 220. However, this method requires an additional linkage structure, which results in an excessively complex structure of the display module. In order to solve the problem, the number of the first coils may be set to be a plurality of, the plurality of first coils are connected to the plurality of first plate bodies 220 in a one-to-one correspondence manner, the first magnetic poles 321 and the second magnetic poles 322 are both strip-shaped members, the plurality of first coils are disposed between the same first magnetic pole 321 and the same second magnetic pole 322, and the first coils may be arranged at intervals along the extending direction of the first magnetic pole 321 and the second magnetic pole 322. That is, all first plate bodies 220 can be driven by the corresponding first coils, so that an additional linkage structure is not required, and the structure of the display module is simpler. Meanwhile, the mode can better ensure that all the first plate bodies 220 rotate synchronously, so that the display effect of the display module is optimized.
Similarly, the number of second coils can set up to a plurality ofly, and a plurality of second coils are connected with a plurality of second plate body 230 one-to-one, and third magnetic pole and fourth magnetic pole are the bar part, are equipped with a plurality of second coils between same third magnetic pole and the same fourth magnetic pole, and these second coils can be arranged along the extending direction interval of third magnetic pole and fourth magnetic pole. At this time, all the second plate bodies 230 can be driven by the corresponding second coils, so that the structure of the display module is simpler. Meanwhile, the manner can better ensure that all the second plates 230 rotate synchronously, so as to optimize the display effect of the display module.
