Abstract
Description
Technical Field
[0001] This utility model relates to a display device, and more particularly to a display device having a camera component. Background Technology
[0002] With advancements in 3D imaging technology, users no longer need to wear 3D glasses to view 3D images. To allow users to view complete 3D images, glasses-free 3D displays utilize one or more cameras to capture the user's image and confirm their position (e.g., head position). The display then adjusts the 3D image according to the user's position to ensure a complete viewing experience. However, if the camera is not pointed at the user, the user must manually adjust the camera angle (e.g., manually adjusting the angle of the glasses-free 3D display). If the user moves their head or changes their viewing position, the camera may not adapt in time, leading to parallax errors that can cause 3D misalignment, ghosting, or eye strain, negatively impacting the viewing experience. Furthermore, manually adjusting the camera may not accurately align with the head, causing tracking errors and preventing the system from providing a stable 3D display. Utility Model Content

[0054] The present invention will be described in detail below with reference to the accompanying drawings and specific embodiments, but this is not intended to limit the present invention.
[0055] Please see Figure 1 , Figure 2 and Figure 3 . Figure 1 This is a schematic diagram of the appearance of the display device in some embodiments of the present invention. Figure 2 This is a partially exploded view of the camera assembly and housing of the display device in some embodiments of the present invention. Figure 3 This is a partial appearance schematic diagram of the display device in some embodiments of the present invention. In some embodiments, such as Figure 1 , Figure 2 and Figure 3 As shown, the display device 100 includes a housing 102 and a camera assembly 104. The housing 102 has an assembly portion 106. The camera assembly 104 includes a roller 108, a camera module 110, and a motor assembly 112. The roller 108 is movably connected to the assembly portion 106 and has a groove 114. The camera module 110 is fixed in the groove 114. The motor assembly 112 is connected to one end of the roller 108 and is used to rotate the roller 108 according to a control signal.
[0056] The housing 102 is used to assemble a display panel 116 of the display device 100. The assembly portion 106 may be located on one side of the housing 102 and protrude from the display panel 116. Here, the area of the housing 102 may be larger than the area of the display panel 116. After the display panel 116 and housing 102 are assembled, the assembly portion 106 is positioned away from the display panel 116. When the roller 108 is movably connected to the assembly portion 106, the camera module 110 may protrude from the display panel 116. The assembly portion 106 may also extend beyond the side of the housing 102 to ensure that the camera module 110 is not obstructed by the display panel 116.
[0057] In some embodiments, the display panel 116 is used to display a three-dimensional image corresponding to a control signal. For example, when a target (such as a user) views the three-dimensional image displayed on the display panel 116 with the naked eye, the imaging effect of the three-dimensional image may be affected by the position, distance, orientation, or angle relationship between the target and the display panel 116. Therefore, the display device 100 can track the target via the camera module 110 to determine the position, distance, orientation, or angle relationship of the target relative to the display panel 116. The display device 100 can adjust the three-dimensional image based on the target tracking result to reduce depth reversal errors, allowing the target to visually perceive the complete three-dimensional image.
[0058] After being driven by the motor assembly 112 from the assembly part 106, the roller 108 can rotate in the pivot direction of the motor assembly 112. In other words, the roller 108 can rotate according to the orientation of the assembly part 106. For example, the assembly part 106 can rotate in a first axial direction (such as...). Figure 3 Extending along the X-axis, the roller 108 can rotate around an axis L1 parallel to the first axial direction. For example, the assembly part 106 extends along a second axial direction (such as...). Figure 3 Extending along the Z-axis, the roller 108 can rotate parallel to an axis L2 of the second axis. Alternatively, multiple assembly parts 106 are respectively disposed along the first and second axes. Correspondingly, the rollers 108 of the multiple camera components 104 are respectively disposed along the assembly parts 106 in different axes, and each performs rotational motion with axis L1 and / or axis L2 as its axis.
[0059] In some embodiments, the roller 108 has good thermal conductivity (e.g., copper). Heat generated by the camera module 110 can be directly or indirectly conducted to the roller 108, and then conducted to the outside atmosphere through the roller 108 (which may mean dissipating heat into the air outside the roller 108) to cool the camera module 110.
[0060] The camera module 110 is used to capture a target image. The target image may refer to an image of a head, an image of an eye, or an image of a pupil of a target. The camera module 110 can transmit the target image to the display device 100 to adjust a control circuit (such as the control board 136 described later) on the display panel 116.
[0061] Motor assembly 112 is fixed to housing 102 and adjacent to roller 108 to connect one end of roller 108. Motor assembly 112 can receive control signals and rotate roller 108 according to the control signals. This enables camera module 110 to track the offset position of the target and capture target images, thereby reducing the positional deviation between the target and camera module 110. Motor assembly 112 may be, for example, but not limited to, a stepper motor or a servo motor.
[0062] In some embodiments, the control signal includes at least one of an angle parameter, an orientation parameter, or a vector parameter, enabling the motor assembly 112 to rotate to a specified angle according to at least one of the aforementioned parameters. For example, if the target is located on the left side of the display panel 116, the display device 100 determines the target position (which may be the world coordinates of the target) based on the captured target image and compares the target position with the optical axis of a lens of the camera module 110 to obtain an angle difference. The display device 100 can generate a corresponding control signal based on this angle difference. The motor assembly 112 uses this control signal to rotate the roller 108 toward the target, causing the optical axis of the lens of the camera module 110 to point toward the target, thereby tracking the target position.
[0063] In some embodiments, such as Figure 3 As shown, the roller 108 has a connecting end (118, 118') on each side, and a groove 114 is located between the two connecting ends (118, 118'). The motor assembly 112 is connected to one of the two connecting ends (118, 118'). For example, the connecting end 118 is connected to the motor assembly 112, so that the motor assembly 112 can drive the connecting end 118 to rotate the roller 108 in the assembly part 106.
[0064] In some embodiments, such as Figure 3 As shown, the assembly 106 has a clip 120 on either side. Each connecting end (118, 118') has a neck 122 and a head 124 (described hereinafter using connecting end 118' as an example). The clip 120 holds the neck 122, and the other connecting end 118 is connected to the motor assembly 112. The two connecting ends (118, 118') and the motor assembly 112 are located on axis L1. Here, the two connecting ends (118, 118') can be positioned by the clip 120 and the motor assembly 112 respectively, so that a rotation axis of the motor assembly 112 is coaxial with axis L1. When the motor assembly 112 rotates, it can precisely adjust the rotation angle of the roller 108, causing the roller 108 to remain stable during rotation.
[0065] Please see Figure 1 and Figure 4 . Figure 4 for Figure 3 An enlarged schematic diagram of region 4 in the middle. In some embodiments, such as Figure 1 and Figure 4 As shown, the diameter D1 of the head 124 is larger than the diameter D2 of the neck 122. Here, the clip 120 clamps the neck 122 to position the roller 108 at a predetermined position on the assembly portion 106. In some embodiments, the width of the neck 122 (width may refer to...) Figure 4The length in the X-axis direction is essentially equal to the width of the clamp 120 (the clamp 120 leaves gaps with the head 124 and the roller 108 respectively to reduce friction). Since the clamp 120 is fixed in a preset position on the assembly part 106, it prevents the roller 108 from shifting in the direction of the axis L1. It should be noted that the preset position of the clamp 120 can be based on the length of the roller 108 (e.g., the length in the X-axis direction is equal to the width of the clamp 120). Figure 1 The length of the middle roller 108 in the X-axis direction and the position where the motor assembly 112 is fixed are determined.
[0066] In some embodiments, such as Figure 3 As shown, two clips (120, 120') can be respectively provided on both sides of the assembly part 106. Clip 120 is clamped to the neck 122 of the connecting end 118, and clip 120' is clamped to the neck 122 of the connecting end 118. The motor assembly 112 is connected to the connecting end 118 (or to the neck 122 of the connecting end 118) so that the two connecting ends (118, 118') and the motor assembly 112 are located on the axis L1.
[0067] In some embodiments, such as Figure 2 and Figure 3 As shown, the motor assembly 112 includes a motor 126, a rotating shaft 128, and a connecting bracket 130. The two ends of the rotating shaft 128 are respectively connected to the motor 126 and either connecting end (118, 118'), allowing the motor 126 to rotate by driving the roller 108 via the rotating shaft 128. The connecting bracket 130 connects the motor 126 and the housing 102 to fix the motor 126 to the assembly part 106 and adjacent to either connecting end (118, 118'). In some embodiments, the connecting bracket 130 has a through hole 131, the center of which is located on the axis L1. Here, the rotating shaft 128 passes through the through hole 131 and connects to the head 124 on either side, and both the rotating shaft 128 and the two connecting ends (118, 118') can be aligned on the axis L1.
[0068] In some embodiments, such as Figure 1 and Figure 2 As shown, the camera module 110 has a circuit board 132 and a plurality of cameras 134. The circuit board 132 is housed in a recess 114, and each camera 134 is coupled to the circuit board 132 and used to acquire target images. The circuit board 132 is used to drive each camera 134 so that each camera 134 can capture target images of the target at different positions.
[0069] In some embodiments, such as Figure 1 and Figure 2As shown, the display device 100 also includes a control board 136. The control board 136 is coupled to the circuit board 132 and the motor assembly 112, and is used to generate control signals based on the target images. For example, after receiving target images captured by each camera 134, the control board 136 can calculate the angular difference between the target and the lens optical axis of each camera 134 based on each target image. The control board 136 generates control signals based on this angular difference. For example, the control board 136 calculates a rotation angle corresponding to the lens optical axis to the target based on this angular difference, and encodes this rotation angle into a control signal to control the deflection angle of the motor 126. The motor 126 can rotate the roller 108 according to this rotation angle, so that the lens optical axis of each camera 134 is aligned with the target. It should be noted that the target may not be fixed; the control board 136 can continuously receive target images captured by each camera 134 and dynamically adjust the angle of the roller 108.
[0070] Please see Figure 5 , Figure 5 for Figure 1 An enlarged schematic diagram of region 5 in the middle. In some embodiments, such as Figure 5 As shown, any of the connection terminals (118, 118') has a through hole 138 communicating with the recess 114. A connection line 140 of the control board 136 is coupled to the circuit board 132 via the through hole 138. For example, a motor 126 is connected to connection terminal 118', which has a through hole 138. The connection line 140 enters the recess 114 from connection terminal 118' via the through hole 138 to couple to the circuit board 132. Target images captured by each camera 134 can be transmitted to the control board 136 via the connection line 140 for analysis. The connection line 140 may be, for example, but not limited to, a flexible printed circuit board (FPC).
[0071] In some embodiments, such as Figure 3 As shown, the circuit board 132 has a mating portion 142, and the groove 114 has a mating member 144. The mating member 144 mates with the mating portion 142 to fix the circuit board 132 in the groove 114. Thus, during the rotation of the roller 108, the circuit board 132 can be fixed and positioned in the groove 114, maintaining a preset shooting angle for each camera 134 on the circuit board 132. The mating portion 142 and the mating member 144 can be, for example, but not limited to, combinations of positioning holes and positioning posts, screw holes and screws, positioning posts and sleeves, or magnets and ferromagnetic components.
[0072] Please see Figure 6 , Figure 6 This is a partial external view of the display device 100 in some embodiments of the present invention, showing the display roller 108 pivotally connected to the bearing 146. In some embodiments, such as Figure 6As shown, the display device 100 includes a bearing 146. The bearing 146 is fixed to the assembly 106 and located between the roller 108 and the motor assembly 112, with either connecting end (118, 118') pivotally connected to the bearing 146. For example, the roller 108 is pivotally connected to the bearing 146 via connecting end 118. When the motor 126 drives the roller 108 to rotate, the bearing 146 reduces the frictional force generated by the rotational motion of the roller 108, thereby improving the accuracy of the rotation angle of the roller 108. In some embodiments, the bearing 146 can be clamped in a clip 120, with the connecting end 118 pivotally connected to the bearing 146. Here, the bearing 146 reduces the frictional force between the connecting end 118 and the clip 120.
[0073] Please refer to the following: Figure 1 , Figure 7 and Figure 8 . Figure 7 This is a partial appearance schematic diagram of the display device 100 in some embodiments of the present invention, showing the camera assembly 104 turning window 148. Figure 8 This is a partial appearance schematic diagram of the display device 100 in some embodiments of the present invention, showing the camera assembly 104 turning shield 150. In some embodiments, such as Figure 1 , Figure 7 and Figure 8 As shown, the assembly unit 106 has a window 148 and a shielding portion 150, which correspond to the roller 108 respectively. The motor assembly 112 selectively rotates the camera module 110 towards either the window 148 or the shielding portion 150 according to a control signal. Specifically, the window 148 corresponds to an effective range (e.g., the effective range for capturing target images by each camera 134) Figure 7 The roller 108 faces the area away from the housing 102, and can rotate within this effective range, allowing each camera 134 to capture target images. If the target is within this effective range, it means the target can visually view the display panel 116. The shielding part 150 can be outside the effective range, meaning that when each camera 134 is turned towards the shielding part 150, it cannot capture target images (e.g., ...). Figure 8 (The area of the middle roller 108 facing the housing 102).
[0074] For example, when the target is within the effective range, the control panel 136 can calculate the angle difference based on the target image to adjust the angle of each camera 134 facing the window 148. When the target is outside the effective range, indicating that the target is not visually viewing the display panel 116, the control panel 136 can turn each camera 134 towards the shielding part 150, causing each camera 134 to stop shooting. It should be noted that the control panel 136 can preset the angle at which each camera 134 turns towards the window 148 or the shielding part 150. When the display device 100 is activated, the control panel 136 can first turn each camera 134 towards the window 148. Conversely, when each camera 134 does not need to capture the target image (or cannot capture the target image), the control panel 136 turns each camera 134 towards the shielding part 150.
[0075] In some embodiments, when the control board 136 receives a recovery signal (which may be input to the control board 136 from an external device), the control board 136 can control each camera 134 to face the window 148, so that the circuit board 132 can re-drive each camera 134.
[0076] In summary, in some embodiments, the display device 100 houses the camera assembly 104 within the groove 114 of the roller 108, and the motor assembly 112 can rotate the roller 108 according to a control signal to adjust the shooting angle of the camera module 110. In some embodiments, the camera module 110 can capture a target image, and the control board 136 of the display device 100 can analyze the target image to determine the target position, thereby generating a control signal based on the target position. This drives the motor assembly 112 to automatically and instantly adjust the shooting angle of the camera module 110, allowing the target to visually receive a correct three-dimensional image.
[0077] The embodiments described above are merely illustrative of the technical ideas and features of this case. Their purpose is to enable those skilled in the art to understand the content of this case and implement it accordingly. They should not be used to limit the scope of the patent in this case. That is, all equivalent changes or modifications made in accordance with the spirit disclosed in this case should still be covered within the scope of the patent application in this case.
