[0024] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of the present invention.

[0027] The LED backlight module's LED board contains numerous LED chips. Sometimes, individual chips fail, causing an abnormal position on the board where the damaged chip was located. This abnormal board can further lead to display errors in the module's image. The common solution is to replace the entire LED board; however, this method results in a shorter lifespan for the board.

[0028] Therefore, the present invention proposes a driving mechanism to help extend the service life of the lamp panel.

[0029] Please see Figure 1 and 2 In one embodiment of the present invention, the driving mechanism 100 includes a rotating body 1 and a first transmission mechanism 2. The rotating body 1 can be configured as a spherical shell, an elliptical shell, a circular plate, an elliptical plate, a rectangular plate, a connecting bracket, etc., and the first transmission mechanism 2 can be configured as a drive motor, a gear transmission mechanism, a connecting rod transmission mechanism, a crank-slider mechanism, etc. The first transmission structure is used to drive the rotating body 1 to rotate around a first preset axis 3. Figure 1 In the middle, the first preset axis 3 is perpendicular to Figure 1 The diagram shows that the outer peripheral wall of the rotating body 1 is used to arrange at least two light chips 4 at intervals along the rotation direction. It is understood that the rotation direction refers to the direction of rotation of the rotating body 1. The rotating body 1 is used to rotate so that one of the light chips 4 rotates to a preset position 5. It is understood that the preset position 5 is generally the position where the light chip 4 is normally operating. With this configuration, when the light chip 4 at the preset position 5 is damaged, the rotating body 1 can be driven to rotate through the first transmission structure, causing the damaged light chip 4 to leave the preset position 5, and causing another light chip 4, spaced apart on the outer peripheral wall of the rotating body 1, to reach the preset position 5. This maintains the preset position 5 in a normal state, thereby enabling the lamp board 200 structure to maintain normal operation and extending the service life of the lamp board 200. In one embodiment, referring to… Figure 1 The light chip 4 can be disposed on the substrate 201 of the backlight module; wherein, the preset position 5 is located on the cutting plane of the rotating body 1, and the cutting plane is parallel to the surface of the substrate 201.

[0030] In some implementations, refer to Figure 4The rotating body 1 is provided with at least two second transmission structures 11, which are connected one-to-one with the light chip 4. The second transmission structure 11 drives the light chip 4 to move from the outer peripheral wall of the rotating body 1 toward the rotation axis of the rotating body 1 (i.e., the aforementioned first preset axis 3). The second transmission structure 11 can be configured as a slide rail structure, a sleeve structure, etc. In this embodiment, when the rotating body 1 needs to be rotated to replace the light chip 4, the second transmission structure 11 can be used to move the light chip 4 toward the rotation axis, causing the light chip 4 to retract from the outer peripheral wall, thereby reducing the risk of the light chip 4 colliding with other external structures during rotation.

[0031] Specifically, refer to Figure 3 and Figure 4 The second transmission structure 11 can be configured to include a moving component 111 and a driving component 112; one end of the moving component 111 is connected to the light chip 4, and the other end of the moving component 111 is connected to the driving component 112; the driving component 112 is mounted on the rotating body 1, and the moving component 111 is movably connected to the rotating body 1. The driving component 112 is used to drive the moving component 111 to move from the outer peripheral wall of the rotating body 1 toward the rotation axis of the rotating body 1. Understandably, the moving component 111 can be indirectly connected to the light chip 4 through other components, or it can be directly connected to the light chip 4.

[0032] Specifically, the drive assembly 112 includes a first rotating wheel 1121, a first connecting member 1122, and a second connecting member 1123. The first rotating wheel 1121 is rotatably connected to the rotating body 1. One end of the first connecting member 1122 is connected to the first rotating wheel 1121, and the other end of the first connecting member 1122 is rotatably connected to the second connecting member 1123. The other end of the second connecting member 1123 is rotatably connected to the moving assembly 111, or the other end of the second connecting member 1123 is used to rotatably connect to the light chip 4. With this configuration, the rotation of the first rotating wheel 1121 drives one end of the first connecting member 1122 connected to it to rotate around the axis of the rotating wheel, thereby causing the other end of the first connecting member 1122 to also rotate around the axis of the rotating wheel. This causes a change in the motion component of the end of the first connecting member 1122 connected to the second connecting member 1123 in the direction of the rotation centerline of the outer peripheral wall of the rotating body 1 towards the rotation centerline of the rotating body 1. Further, in one embodiment, the second connecting member 1123 is made of a rigid material, allowing it to be rotatably connected to the first connecting member 1122, thereby driving the movable component 111 or the light chip 4 connected to the second connecting member 1123 to move from the outer peripheral wall of the rotating body 1 towards the rotation centerline of the rotating body 1. Understandably, since the movable component 111 and the light chip 4 are connected together, the second connecting member 1123 can move the light chip 4 whether it is connected to the movable component 111 or directly connected to the light chip 4. In another embodiment, the second connecting member 1123 is made of an elastic material, allowing the first connecting member 1122 to directly stretch the second connecting member 1123 when it rotates; for example, after the first connecting member 1122 rotates, the second connecting member 1123 is stretched and also rotates relative to the first connecting member 1122; simultaneously, the second connecting member 1123 also rotates relative to the movable component 111 or the light chip 4 connected to it. Understandably, the first connector 1122 and the second connector 1123 can be fixedly connected or movably connected at this time; in general, regardless of whether the first connector 1122 and the second connector 1123 are fixedly connected or movably connected, they can rotate relative to each other due to the elastic material.

[0033] In other embodiments, the drive assembly 112 includes two first rotating wheels 1121, two first connecting members 1122, and two second connecting members 1123. The outer peripheral wall of the first rotating wheel 1121 is provided with a toothed structure, for example, the first rotating wheel 1121 is configured as a gear, and the two first rotating wheels 1121 mesh with each other. Each of the two first connecting members 1122 is connected to one of the first rotating wheels 1121, for example, by welding, plugging, or other methods to fix the first connecting member 1122 to the first rotating wheel 1121. The two first connecting members 1122 and the two second connecting members 1123 are connected one-to-one, and the ends of the two second connecting members 1123 facing away from the first connecting members 1122 are respectively used to connect the opposite ends of the moving assembly 111 or the light chip 4. In this embodiment, the stability and uniformity of the movement of the light chip 4 from the outer peripheral wall of the rotating body 1 toward the rotation centerline of the rotating body 1 can be improved.

[0034] Furthermore, in some embodiments, the moving component 111 may include a third transmission structure 1112, which is connected to the light chip 4. The third transmission structure 1112 is used to drive the light chip 4 to rotate around the second preset axis 6. The angle between the tangent plane of the rotation direction of the rotating body 1 and the second preset axis 6 is less than 90 degrees. For example, this angle can be set to 0 degrees, 10 degrees, 20 degrees, 30 degrees, etc. The third transmission structure 1112 is connected to the driving component 112, which is used to drive the third transmission structure 1112 to move from the outer peripheral wall of the rotating body 1 toward the rotation axis of the rotating body 1. By driving the light chip 4 to rotate around the second preset axis 6 through the third transmission structure 1112, the light emission direction of the light chip 4 can be adjusted, thereby achieving the adjustment of the wide and narrow viewing angles. It can be understood that in one embodiment, the first preset axis 3 can be along the X direction, the light chip 4 is in the Z direction, and the light chip 4 is located in the tangent plane of the rotation direction of the rotating body 1. For example, this tangent plane is parallel to the... Figure 4In the XY plane, the angle between the tangent plane of the rotation direction of the rotating body 1 and the second preset axis 6 is 0 degrees. By rotating the light chip 4 around the second preset axis 6, the angle of the light chip 4 on the tangent plane can be changed, thus changing the light emission of the light chip 4 and adjusting the wide and narrow viewing angles. When the angle between the tangent plane of the rotation direction of the rotating body 1 and the second preset axis 6 is less than 90 degrees, that is, when the second preset axis 6 is not perpendicular to the XY plane, rotating the light chip 4 around the second preset axis 6 can change the angle of the light chip 4 on the tangent plane; while when the angle between the tangent plane of the rotation direction of the rotating body 1 and the second preset axis 6 is equal to 90 degrees, that is, when the second preset axis 6 is perpendicular to the XY plane, rotating the light chip 4 around the second preset axis 6 does not change the tilt angle of the light chip 4 on the tangent plane. Furthermore, in one embodiment, by setting the lamp panel 200 to include multiple driving mechanisms 100, and having the third transmission structure 1112 in the multiple driving mechanisms 100 drive the light chip 4 connected thereto, the light emission direction of the multiple light chips 4 can be adjusted to tilt as a whole towards the center of the tangent plane or outward, thereby achieving the adjustment of the wide and narrow viewing angles of the lamp panel.

[0035] Furthermore, in one embodiment, the third transmission structure 1112 includes a rotating shaft 1112a and a mating structure 1111. The mating structure 1111 is movably connected to the rotating body 1 and is used to move from the outer peripheral wall of the rotating body 1 toward the rotation axis of the rotating body 1. The rotating shaft 1112a is rotatably connected to the mating structure 1111 and is used to connect to the light chip 4. The light chip 4 is used to rotate around the second preset axis 6 as the rotating shaft 1112a rotates. Specifically, the movable connection between the mating structure 1111 and the rotating body 1 can be configured as follows: the mating structure 1111 includes a slider, and the rotating body 1 is provided with a sliding groove extending from the outer peripheral wall of the rotating body 1 toward the rotation centerline of the rotating body 1; alternatively, the mating structure 1111 includes a sliding rod, and the rotating body 1 is provided with a sleeve extending from the outer peripheral wall of the rotating body 1 toward the rotation centerline of the rotating body 1, with the sliding rod moving within the sleeve. It is understood that the requirement is simply to allow the moving part to move on the rotating body 1 from the outer peripheral wall toward the rotation centerline. The light chip 4 can be fitted onto the rotating shaft 1112a in a tight fit manner, thereby driving the rotation of the light chip 4 through the rotation of the rotating shaft 1112a. Alternatively, the light chip 4 can be fixedly connected to the rotating shaft 1112a by pasting, plugging, snapping, or other methods. It is understood that the axis of the rotating shaft 1112a is the second preset axis 6. In this embodiment, the rotating shaft 1112a facilitates easier adjustment of the rotation angle.

[0036] Furthermore, the third transmission structure 1112 also includes a second rotating wheel 1112b, and the moving component 111 also includes a fixed plate 1113; the fixed plate 1113 is respectively connected to the driving component 112 and the mating structure 1111, and the second rotating wheel 1112b is rotatably connected to the fixed plate 1113; the outer peripheral wall of the second rotating wheel 1112b is provided with a second helical structure, and the outer peripheral wall of the rotating shaft 1112a is provided with a first helical structure, and the first helical structure is pulsatorically connected to the second helical structure. With this configuration, the second rotating wheel 1112b can provide support force to the rotating shaft 1112a, making the rotating shaft 1112a more stable and uniform during rotation. The rotating shaft 1112a can be configured as a worm gear, and the second rotating wheel 1112b can be configured as a worm wheel.

[0037] The present invention also proposes a lamp panel 200, with reference to Figure 1 and Figure 4 The light panel 200 includes a substrate 201 and at least one light chip assembly 202. The light chip assembly 202 is mounted on the substrate 201. The light chip assembly 202 includes at least two light chips 4 disposed on the outer peripheral wall of the rotating body 1 and spaced apart along the rotation direction of the rotating body 1. The light chip assembly 202 also includes the driving mechanism 100 in the aforementioned embodiment. The driving mechanism 100 is connected to the substrate 201 and drives the light chip assembly 202 to rotate around a first preset axis 3. The substrate 201 is provided with at least one receiving cavity 201a, the receiving cavity 201a is provided with a first opening 201b, and a preset position 5 is located in the first opening 201b. When the light chip 4 rotates to the preset position 5, the light emitted by the light chip 4 propagates outward through the first opening 201b. Understandably, the substrate 201 may also have a first opening 201b on opposite sides, with a preset position 5 located in one of the first openings 201b, and multiple preset positions 5 located on the same side of the substrate 201; the first opening 201b on the other side of the substrate 201 can be used for the drive mechanism 100 to pass through. That is, the drive mechanism 100 can be completely housed in the receiving cavity 201a, or it can be partially located outside the substrate 201 and partially located inside the receiving cavity 201a.

[0038] Furthermore, the lamp panel 200 also includes at least one sensor 203, which is configured one-to-one with the drive mechanism 100. The drive mechanism 100 includes a power source for driving the first transmission structure, and the sensor 203 is electrically connected to the power source. The sensor 203 is used to detect whether the light chip 4 located at the preset position 5 is working properly. The sensor 203 can be configured as a photoelectric sensor, etc., to detect whether the light chip 4 at the preset position 5 is emitting light normally. If the light chip 4 at the preset position 5 emits light abnormally, a signal is sent to the power source, causing the power source to drive the rotating body 1 of the drive mechanism 100 to rotate, so that the abnormally emitting light chip 4 leaves the preset position 5; and another light chip 4 spaced apart on the outer peripheral wall of the rotating body 1 reaches the preset position 5, thereby enabling the lamp panel 200 structure to maintain normal operation. The setting of the sensor 203 helps to improve the automation level of the drive mechanism 100.

[0039] In one embodiment, the lamp board 200 further includes a circuit board 204 and at least one set of pad structures. The circuit board 204 is connected to the substrate 201. The circuit board 204 has a second opening 201c, which communicates with a first opening 201b. The pad structures include a first pad 205a and a second pad 205b. The first pad 205a is located on the circuit board 204, and the second pad 205b is located on the lamp chip 4. The second pad 205b is used to rotate with the lamp chip 4 to abut against the first pad 205a. The pad structures are used for circuit conduction of the lamp chip 4. When the first pad 205a and the second pad 205b abut against each other, contact conductivity can occur. This configuration allows for rapid separation of the faulty lamp chip 4 from the circuit board 204 and rapid conduction of the intact lamp chip 4 to the circuit board 204, thereby improving the circuit conduction efficiency of the lamp chip 4.

[0040] Furthermore, the specific structure of the drive mechanism 100 in the lamp panel 200 refers to the above embodiments. Since the lamp panel 200 adopts all the technical solutions of all the above embodiments, it has at least all the beneficial effects brought about by the technical solutions of the above embodiments, which will not be described in detail here.

[0041] The present invention also proposes a backlight module, which includes the lamp panel 200 in the foregoing embodiments. Since this backlight module adopts all the technical solutions of all the above embodiments, it possesses at least all the beneficial effects brought about by the technical solutions of the above embodiments, which will not be elaborated upon here.

[0042] The above description is merely an exemplary embodiment of the present invention and does not limit the patent scope of the present invention.
