Description

Technical Field

[0001] The present invention relates to a display device and a control method for an optical sensing unit, and particularly to a display device and a control method capable of conveniently and accurately controlling the optical sensing unit to reach a target position. Background Art

[0002] With the popular application of displays, especially high-end displays, people's requirements for the accuracy of color performance are getting higher and higher. For example, parameters such as the screen color gamut, color difference, color temperature, and gamma all have high-precision requirements. Although these functional parameters can meet customer requirements when the display leaves the factory, as the usage time of the display increases, due to the aging of components inside the display such as the display panel and electrical components, the accuracy of the foregoing functional parameters will deviate.

[0003] To solve this problem, color correctors have been embedded in displays. The color corrector is usually hidden in the housing of the display, and a motor or a mechanical sensor is used to position and confirm the color corrector. However, after long-term use, mechanical aging often causes inaccurate positioning of the color corrector, resulting in the color corrector being unable to move to the correct measurement position, thus causing problems such as abnormal measurement results or improper retraction. Summary of the Invention

[0004] The purpose of the present invention is to provide a display device and a control method for an optical sensing unit to solve the above problems.

[0005] To achieve the above purpose, the present invention provides a display device, which includes a housing, a display unit, an optical sensing unit, a driving unit, and a processing unit. The housing is provided with a first sensing member; the display unit is disposed in the housing; the optical sensing unit is movably connected to the housing, and the optical sensing unit is provided with an optical sensing member and a second sensing member; the driving unit is connected to the optical sensing unit, and the driving unit is used to drive the optical sensing unit to move; the processing unit is electrically connected to the first sensing member, the optical sensing unit, and the driving unit respectively. When using the optical sensing unit, the driving unit drives the optical sensing unit to reach an initial deployment position, the processing unit confirms a first coordinate position of the first sensing member and a second coordinate position of the second sensing member, and confirms a fine-tuning direction and a fine-tuning angle of the optical sensing unit according to the first coordinate position and the second coordinate position, and the driving unit drives and adjusts the optical sensing unit according to the fine-tuning direction and the fine-tuning angle to reach a target deployment position.

[0006] As an alternative technical solution, the processing unit determines the angle between the first sensing element and the second sensing element on a coordinate plane according to the first coordinate position and the second coordinate position. The coordinate plane is parallel or perpendicular to the display surface of the display unit. The processing unit determines the fine-tuning direction and the fine-tuning angle on the coordinate plane according to the angle, and the driving unit drives the optical sensing unit to move to a target position on the coordinate plane according to the fine-tuning direction and the fine-tuning angle.

[0007] As an alternative technical solution, the processing unit determines a first angle between the first sensing element and the second sensing element on a first coordinate plane according to the first coordinate position and the second coordinate position. The first coordinate plane is parallel to the display surface of the display unit.

[0008] As an alternative technical solution, the driving unit includes a first motor, and the first motor is configured to drive the optical sensing unit to rotate along a first rotation axis. The first rotation axis is perpendicular to the display surface of the display unit. The first motor drives the optical sensing unit to rotate along the first rotation axis to the first target position according to the first fine-tuning direction and the first fine-tuning angle.

[0009] As an alternative technical solution, the processing unit determines a second angle between the first sensing element and the second sensing element on a second coordinate plane according to the first coordinate position and the second coordinate position. The second coordinate plane is perpendicular to the display surface of the display unit. The processing unit determines a second fine-tuning direction and a second fine-tuning angle on the second coordinate plane according to the second angle, and the driving unit drives the optical sensing unit to move to a second target position on the second coordinate plane according to the second fine-tuning direction and the second fine-tuning angle.

[0010] As an alternative technical solution, the driving unit includes a second motor, and the second motor is configured to drive the optical sensing unit to rotate along a second rotation axis. The second rotation axis is parallel to the display surface of the display unit. The second motor drives the optical sensing unit to rotate along the second rotation axis to the second target position according to the second fine-tuning direction and the second fine-tuning angle.

[0011] As an alternative technical solution, when the optical sensing unit is in a storage position, the processing unit further determines a third coordinate position of the second sensing element, and determines a stepping parameter of the first motor according to the second coordinate position and the third coordinate position.

[0012] As an alternative technical solution, the first sensing element is a first acceleration sensor, and the second sensing element is a second acceleration sensor.

[0013] As an alternative technical solution, the optical sensing unit includes a first component and a second component. The optical sensing member and the second sensing member are disposed on the first component. When the optical sensing unit is in the storage position, the first component is sleeved inside the second component; when the optical sensing unit is in the deployed position, the first component extends out of the second component.

[0014] In addition, the present invention further provides a control method for an optical sensing unit, which is applicable to a display device. The display device includes a housing, a display unit, an optical sensing unit, and a driving unit. The display unit is disposed in the housing. The housing is provided with a first sensing member. The optical sensing unit is provided with an optical sensing member and a second sensing member. The driving unit is connected to the optical sensing unit and is used to drive the optical sensing unit to move. When using the optical sensing unit, the control method includes the following steps:

[0015] Step A, driving the optical sensing unit to move to the initial deployed position;

[0016] Step B, confirming the first coordinate position of the first sensing member and the second coordinate position of the second sensing member;

[0018] Step D, driving and adjusting the optical sensing unit to the target deployed position according to the fine-tuning direction and the fine-tuning angle.

[0019] As an alternative technical solution, step C includes:

[0037] The display device 1000 of the present invention includes a housing 100, a display unit 200, an optical sensing unit 300, a driving unit 400, and a processing unit 500. A first sensing element 110 is provided on the housing 100, and the display unit 200 is disposed on the housing 100. The optical sensing unit 300 is movably connected to the housing 100. The optical sensing unit 300 is provided with an optical sensing element 310 and a second sensing element 320. The driving unit 400 is connected to the optical sensing unit 300, and the driving unit 400 is used to drive the optical sensing unit 300 to move. The processing unit 500 is electrically connected to the first sensing element 110, the optical sensing unit 300, and the driving unit 400 respectively. In this embodiment, the first sensing element 110 is a first acceleration sensor (G-sensor), and the second sensing element 320 is a second acceleration sensor (G-sensor).

[0038] When using the optical sensing unit 300, the driving unit 400 drives the optical sensing unit 300 to reach the initial deployment position. The processing unit 500 confirms the first coordinate position of the first sensing element 110 and the second coordinate position of the second sensing element 220, and determines whether the optical sensing unit 300 needs fine-tuning based on the first coordinate position and the second coordinate position. If fine-tuning is required, the fine-tuning direction and the fine-tuning angle can be determined, and the driving unit 400 drives and adjusts the optical sensing unit 300 according to the fine-tuning direction and the fine-tuning angle to reach the target deployment position.

[0039] The display device 1000 of the present invention is provided with an optical sensing unit 300 capable of performing optical sensing and calibration. When the optical sensing unit 300 is not in use, the optical sensing unit 300 is hidden and stored in the housing 100 (as Figure 5 shown). When it is desired to use the optical sensing unit 300, the driving unit 400 first drives the optical sensing unit 300 from the storage position to the initial deployment position according to the preset driving conditions, and then automatically fine-tunes it to the target deployment position. When the optical sensing unit 300 is located at the target deployment position, the optical sensing member 310 on the optical sensing unit 300 can correspond to the exact center of the display panel 100, so that optical sensing of the screen center point and subsequent calibration can be performed.

[0040] The aforementioned preset driving conditions are, for example, the original factory settings that enable the display device 1000 to drive the optical sensing unit 300 to the target position. In theory, when the driving unit 400 drives the optical sensing unit 300 from the storage position to the initial deployment position according to the preset driving conditions, the optical sensing unit 300 (especially the optical sensing member 310) will correspond to the exact center of the display panel 200 (the target position), so that optical measurement and calibration of the screen center point of the display panel 200 can be performed. However, due to long-term use, component precision, etc., the preset driving conditions based on the original factory settings often cannot drive the optical sensing unit 300 to the target position but there will be slight deviations.

[0041] To automatically correct the aforementioned slight deviation and ensure that the optical sensing unit 300 can reach the target deployment position for subsequent optical sensing and calibration. In the present invention, a first sensing member 110 serving as a reference reference point is provided on the housing 100, and a second sensing member 320 is provided on the optical sensing member 300. The first sensing member 110 can obtain its own first coordinate position and use it as the reference reference position. When the optical sensing unit 300 reaches the initial deployment position, the second sensing member 320 can obtain its own second coordinate position. In this embodiment, the first coordinate position and the second coordinate position are coordinate values in the three-dimensional coordinate system xyz. The first coordinate position can be defined as having the first coordinate value (x1, y1, z1), and the second coordinate position can be defined as having the second coordinate value (x2, y2, z2). The processing unit 500 confirms the angle between the two based on the first coordinate value (x1, y1, z1) and the second coordinate value (x2, y2, z2). Since the first coordinate position corresponding to the first sensing member 110 (i.e., the first coordinate value (x1, y1, z1)) is the reference reference position, the fine-tuning direction and the fine-tuning angle between the second sensing member 320 and the target deployment position can be confirmed. And since the relative positional relationship between the second sensing member 320 and the optical sensing member 310 is fixed. In this embodiment, when the optical sensing unit 300 reaches the target deployment position, the optical sensing unit 300 is parallel to the display panel 200. At this time, the distance between the second sensing member 320 and the display surface 200 is equal to the distance between the optical sensing member 310 and the display surface 200 (or, as Figure 6 shown, the optical sensing member 310 and the second sensing member 320 are electrically disposed on one surface of the circuit board 330, and the distance between the optical sensing member 310 and this surface of the circuit board 330 is equal to the distance between the second sensing member 320 and this surface of the circuit board 330), so that the fine-tuning direction and the fine-tuning angle can be considered as the fine-tuning direction and the fine-tuning angle between the optical sensing member 310 and the target deployment position. In another embodiment, the second sensing member 320 and the optical sensing member 310 may have other positional relationships. Since the relative positional relationship between the optical sensing member 310 and the second sensing member 320 is fixed and calculable when the optical sensing unit 300 is manufactured, the user can confirm the fine-tuning direction and the fine-tuning angle between the optical sensing member 310 and the target deployment position through the fine-tuning direction and the fine-tuning angle between the second sensing member 320 and the target deployment position and the positional relationship between the optical sensing member 310 and the second sensing member 320.

[0042] The display device 1000 of the present invention sets a first sensing member 110 serving as a reference reference point on the housing 100, and sets a second sensing member 320 on the optical sensing unit 300. When the optical sensing unit 300 reaches the initial deployment position, it is confirmed whether the optical sensing unit 300 needs fine adjustment according to the coordinate positions of the first sensing member 110 and the second sensing member 320. If fine adjustment is required, the fine adjustment direction and fine adjustment angle can also be determined. Then, the driving unit 400 drives the optical sensing unit 300 to the target deployment position according to the fine adjustment direction and fine adjustment angle, improving the precise positioning of the optical sensing unit 300 and ensuring subsequent sensing and calibration results.

[0043] In actual operation, when confirming the fine adjustment direction and fine adjustment angle, the processing unit 500 confirms the included angle between the first sensing member 110 and the second sensing member 320 on a coordinate plane according to the first coordinate position (corresponding to the first coordinate values (x1, y1, z1)) and the second coordinate position (corresponding to the second coordinate values (x2, y2, z2)). The coordinate plane is parallel or perpendicular to the display surface of the display unit 200. The processing unit 500 confirms the fine adjustment direction and fine adjustment angle on the coordinate plane according to the included angle, and the driving unit 400 drives the optical sensing unit 300 to move to the target position on the coordinate plane according to the fine adjustment direction and fine adjustment angle.

[0044] In an embodiment, when confirming the fine adjustment direction and fine adjustment angle, the processing unit 500 can confirm the first included angle a1 between the first sensing member 110 and the second sensing member 220 on the first coordinate plane xy according to the first coordinate values (x1, y1, z1) and the second coordinate values (x2, y2, z2). The first coordinate plane xy is parallel to the display surface of the display unit 200. The processing unit 500 confirms the first fine adjustment direction and the first fine adjustment angle on the first coordinate plane xy according to the first included angle a1, and the driving unit 400 drives the optical sensing unit 300 to move to the first target position on the first coordinate plane xy according to the first fine adjustment direction and the first fine adjustment angle.

[0045] As Figure 3 shown, in this embodiment, the first sensing member 110 is located at a position corresponding to the center line of the display panel 200 on the housing 100 for convenience of subsequent calculation. As Figure 4A shown, the processing unit 500 confirms that the first sensing member 110 has the first sub-coordinate values (x1, y1) on the first coordinate plane xy according to the x-axis coordinate and y-axis coordinate of the first coordinate values (x1, y1, z1) corresponding to the first coordinate plane xy (see Figure 4A midpoint P1). At the same time, the processing unit 500 confirms that the second sensing member 320 has the second sub-coordinate values (x2, y2) on the first coordinate plane xy according to the x-axis coordinate and y-axis coordinate of the second coordinate values (x2, y2, z2) corresponding to the first coordinate plane xy (seeFigure 4A midpoint Q1), and then calculate the included angle between the first sub-coordinate values (x1, y1) and the second sub-coordinate values (x2, y2) on the first coordinate plane xy as the first included angle a1. Based on the first included angle a1, the first fine-tuning direction and the first fine-tuning angle can be determined.

[0046] In this embodiment, the counterclockwise direction is defined as the positive direction, and the clockwise direction is defined as the negative direction. For example, Figure 4A As shown, the first included angle a1 from the second sub-coordinate values (x2, y2) (i.e., point Q1) to the first sub-coordinate values (x1, y1) (i.e., point P1) is, for example, +5°. In this embodiment, since the first sensing member 110 serves as a reference point, which corresponds to the center line of the display panel 200, and the projection of the center line of the display panel 200 on the first coordinate plane xy coincides with the y-axis, the first sub-coordinate values (x1, y1) of the first coordinate position of the first sensing member 110 on the first coordinate plane xy can be regarded as being located on the y-axis. Since the first target position of the optical sensing unit 300 is to align with the center line of the display panel 200, no other calculations are required. Driving the driving unit 400 to rotate the optical sensing unit 300 counterclockwise by 5° (i.e., the first included angle a1) can make the optical sensing unit 300 move to the first target position on the first coordinate plane xy (i.e., the first fine-tuning direction is counterclockwise rotation, and the first fine-tuning angle is 5°). At this time, the projection of the optical sensing unit 300 on the first coordinate plane xy falls on the y-axis, that is, the optical sensing unit 300 (especially the optical sensing member 310) is aligned with the center line of the display panel 200.

[0047] In this embodiment, the driving unit 400 includes a first motor 410. The first motor 410 is used to drive the optical sensing unit 300 to rotate along the first rotation axis A1, and the first rotation axis A1 is perpendicular to the first coordinate plane xy. The first motor 410 drives the optical sensing unit 300 to rotate along the first rotation axis A1 to the first target position according to the first fine-tuning direction and the first fine-tuning angle. In actual operation, the first rotation axis A1 can pass through the coordinate origin (0, 0) of the first coordinate plane xy. In the present invention, the first motor 410 drives the optical sensing unit 300 from the storage position to the initial deployment position, and then after determining the first fine-tuning direction and the first fine-tuning angle, the first motor 410 drives the optical sensing unit 300 to the first target position.

[0048] In one embodiment, when confirming the fine-tuning direction and fine-tuning angle, the processing unit 500 further confirms a second included angle a2 between the first sensing member 110 and the second sensing member 220 on the second coordinate plane yz according to the first coordinate values (x1, y1, z1) and the second coordinate values (x2, y2, z2). The second coordinate plane yz is perpendicular to the display surface of the display unit 200. The processing unit 500 confirms the second fine-tuning direction and the second fine-tuning angle on the second coordinate plane yz according to the second included angle a2. The driving unit 400 drives the optical sensing unit 300 to move to a second target position on the second coordinate plane yz according to the second fine-tuning direction and the second fine-tuning angle.

[0049] As Figure 4B shown, the processing unit 500 confirms that the first sensing member 110 has third sub-coordinate values (y1, z1) on the second coordinate plane yz according to the y-axis coordinate and the z-axis coordinate of the first coordinate values (x1, y1, z1) corresponding to the second coordinate plane yz (see Figure 4B midpoint P2). At the same time, the processing unit 500 confirms that the second sensing member 320 has fourth sub-coordinate values (y2, z2) on the second coordinate plane yz according to the y-axis coordinate and the z-axis coordinate of the second coordinate values (x2, y2, z2) corresponding to the second coordinate plane yz (see Figure 4B midpoint Q2). Then, the included angle between the third sub-coordinate values (y1, z1) and the fourth sub-coordinate values (y2, z2) on the second coordinate plane yz is calculated and used as the second included angle a2. According to the second included angle a2, the second fine-tuning direction and the second fine-tuning angle can be confirmed.

[0050] In this embodiment, the counterclockwise direction is defined as the positive direction, and the clockwise direction is defined as the negative direction. As Figure 4B shown, the second included angle a2 from the fourth sub-coordinate values (y2, z2) (i.e., point Q2) to the third sub-coordinate values (y1, z1) (i.e., point P2) is, for example, -3°. In this embodiment, since the first sensing member 110 is used as a reference point, it corresponds to the center line of the display panel 200, and its projection on the second coordinate plane yz coincides with the y-axis. When the second included angle a2 is calculated, the driving unit 400 drives the optical sensing unit 300 to rotate clockwise by 3° (i.e., the second included angle a2), so that the optical sensing unit 300 can reach the second target position on the second coordinate plane yz (i.e., the second fine-tuning direction is clockwise rotation, and the first fine-tuning angle is 3°). At this time, the optical sensing unit 300 can be parallel to the first coordinate plane xy, that is, the optical sensing unit 300 is parallel to the display surface of the display panel 200.

[0051] In this embodiment, the driving unit 400 includes a second motor 420. The second motor 420 is used to drive the optical sensing unit 300 to rotate along a second rotation axis A2, and the second rotation axis A2 is parallel to the display surface of the display unit 200. The second motor 420 drives the optical sensing unit 300 to rotate along the second rotation axis A2 to a second target position according to a second fine-tuning direction and a second fine-tuning angle. In actual operation, the first rotation axis A1 can pass through the origin (0, 0) of the first coordinate plane xy. The display device 1000 of the present invention adjusts the positions of the optical sensing elements 310 and 320 (pitch and roll adjustments) by the rotations of the first motor 410 and the second motor 420.

[0052] In the present invention, since the first coordinate plane xy and the second coordinate plane yz are perpendicular to each other, when the optical sensing unit 300 (specifically the second sensing element 320) reaches the target position in both the first coordinate plane xy and the second coordinate plane yz, it can be considered that the optical sensing unit 300 reaches the target deployment position. At this time, the optical sensing unit 300 (specifically the second sensing element 320) is aligned with the center line of the display panel 200 and parallel to the display panel 200. Generally, the optical sensing element 310 is aligned with the second sensing element 320, so it can be considered that the optical sensing element 310 is aligned with the center line of the display panel 200 and parallel to the display panel 200 at this time. In actual operation, the length of the optical sensing unit 300 and the setting position of the optical sensing element 310 can be preset so that the optical sensing element 310 is aligned with the exact center point of the display panel 200 at this time. Thus, after reaching the initial deployment position, the optical sensing unit 300 can reach the target deployment position through automatic fine-tuning, ensuring precise positioning and guaranteeing subsequent measurement and calibration effects.

[0053] In this embodiment, as Figure 1 shown, when the optical sensing unit 300 reaches the target deployment position, the housing 100 where the first sensing element 110 is located (specifically the surface opposite to the optical sensing unit 300) is parallel to the optical sensing unit 300 where the optical sensing element 310 is located (specifically the surface opposite to the housing 100). In actual operation, the sensing surfaces of the first sensing element 110 and the second sensing element 320 are both small planes, so they are regarded as points when calculating the coordinates of the first sensing element 110 and the second sensing element 320. In another embodiment, when the optical sensing unit 300 reaches the target deployment position, the plane extended by the small sensing surface of the first sensing element 110 is parallel to the plane extended by the small sensing surface of the optical sensing element 310. Further, when the first sensing element 110 protrudes from the housing 100 by a certain distance, the plane extended by the small sensing surface of the first sensing element 110 can coincide with the plane extended by the small sensing surface of the optical sensing element 310.

[0054] It should be noted that during the automatic fine-tuning process, the first motor 410 can first drive the optical sensing unit 300 to the first target position, and then the second motor 420 can drive the optical sensing unit 300 to the second target position; or the second motor 420 can first drive the optical sensing unit 300 to the second target position, and then the first motor 410 can drive the optical sensing unit 300 to the first target position. The user can operate according to actual needs without limitation.

[0055] In actual operation, it is possible that the optical sensing unit 300 (especially the optical sensing element 310) is not aligned with the center line of the display panel 200 and the optical sensing unit 300 (especially the optical sensing element 310) is not parallel to the display surface of the display panel at the same time. Instead, there may be only one such situation, and the user can make adjustments according to the actual situation.

[0056] In actual operation, in order for the driving unit 400 to smoothly drive the optical sensing unit 300 to the target position after determining the fine-tuning angle and the fine-tuning direction, the present invention also pre-collects and processes the relevant driving parameters of the driving unit 400. When the optical sensing unit 300 is in the storage position, the processing unit 500 confirms the third coordinate position of the second sensing element 220, and confirms the stepping parameter of the first motor 410 according to the second coordinate position and the third coordinate position.

[0057] Please refer to Figure 4C , Figure 4C is a schematic diagram of the coordinates of the second sensing element in the first coordinate plane when the optical sensing unit of the present invention is in the storage position and the initial deployment position. Taking the first motor 410 as an example, the third coordinate position can be defined as having a third coordinate value (x3, y3, z3) (corresponding to Figure 4C midpoint Q3), and the processing unit 500 can confirm the moving angle a3 of the second sensing element 320 in the xy plane of the first coordinate plane according to the second coordinate value (x2, y2, z2) (corresponding to Figure 4C midpoint Q1) and the third coordinate value (x3, y3, z3). The processing unit 500 determines the stepping parameter of the first motor 410 according to the actuation information of the first motor 410 in combination with the moving angle a3. For example, when the first motor 410 rotates one circle, how much is the moving angle of the second sensing element 320 in the xy plane of the first coordinate plane, so as to facilitate controlling the first motor 410 after determining the first fine-tuning angle and the first fine-tuning direction, so that the optical sensing unit 300 reaches the first target position.

[0058] In this embodiment, the first sensing member 110 is disposed corresponding to the center line of the display panel 200. In actual operation, the first sensing member 110 may also be located at other positions on the housing 100. When the first sensing member 110 is disposed corresponding to the center line of the display panel 200, the included angle between the first coordinate value of the first sensing member 110 on the first coordinate plane xy and the y-axis (i.e., the center line of the display panel 200) is 0°. When the first sensing member 110 is located at other positions, when calculating the first fine-tuning direction and the first fine-tuning angle, the included angle between the first sensing member 110 and the y-axis (i.e., the center line of the display panel 200) needs to be considered, and the other calculation methods are the same. The calculation method of the second coordinate plane yz is similar to that of the first coordinate plane xy.

[0059] In addition, the present invention further provides a control method for an optical sensing unit, which is applicable to a display device 1000. The display device 1000 includes a housing 100, a display unit 200, an optical sensing unit 300, and a driving unit 400. The display unit 200 is disposed on the housing 100. The housing 100 is provided with a first sensing member 110. The optical sensing unit 300 is provided with an optical sensing member 310 and a second sensing member 320. The driving unit 400 is connected to the optical sensing unit 300 and is used to drive the optical sensing unit 300 to move. When using the optical sensing unit 300, the control method includes the following steps.

[0060] Step A: Drive the optical sensing unit 300 to move to the initial deployment position. The driving unit 400 includes a first motor 410 and a second motor 420. The first motor 410 has a first rotating shaft A1, and the first rotating shaft A1 is perpendicular to the display surface of the display panel 200. The second motor 420 has a second rotating shaft A2, and the second rotating shaft A2 is parallel to the display surface of the display panel 200. When the optical sensing unit 300 is not in use, it is hidden and stored in the housing 100. When the optical sensing unit 300 needs to be used, it can be first driven to the initial deployment position by the first motor 410.

[0061] Step B: Confirm the first coordinate position of the first sensing member 110 and the second coordinate position of the second sensing member 320. In this embodiment, the first coordinate position and the second coordinate position are coordinate values in a three-dimensional coordinate system xyz. The first coordinate position can be defined as having a first coordinate value (x1, y1, z1), and the second coordinate position can be defined as having a second coordinate value (x2, y2, z2).

[0062] Step C: Confirm the fine-tuning direction and fine-tuning angle of the optical sensing unit 300 based on the first coordinate position and the second coordinate position. The processing unit 500 confirms the angle between the two based on the first coordinate values (x1, y1, z1) and the second coordinate values (x2, y2, z2). Since the first sensing element 110 is the reference position, the fine-tuning direction and fine-tuning angle between the second sensing element 320 and the target deployment position can be confirmed. And because the relative positional relationship between the second sensing element 320 and the optical sensing element 310 is fixed. In this embodiment, the optical sensing element 310 and the second sensing element 320 are adjacently arranged on the optical sensing unit 300. When the optical sensing unit 300 reaches the target deployment position, the optical sensing unit 300 is parallel to the display panel 200. At this time, the distance between the second sensing element 320 and the display surface 200 is equal to the distance between the optical sensing element 310 and the display surface 200 (or, as Figure 6 shown, the optical sensing element 310 and the second sensing element 320 are adjacently arranged on one surface of the circuit board 330, and the distance between the optical sensing element 310 and this surface of the circuit board 330 is equal to the distance between the second sensing element 320 and this surface of the circuit board 330). Thus, this fine-tuning direction and this fine-tuning angle can be considered as the fine-tuning direction and fine-tuning angle between the optical sensing element 310 and the target deployment position. In another embodiment, the second sensing element 320 and the optical sensing element 310 may have other positional relationships. Since when the optical sensing unit 300 is manufactured, the relative positional relationship between the optical sensing element 310 and the second sensing element 320 is fixed and can be calculated, the user can confirm the fine-tuning direction and fine-tuning angle between the optical sensing element 310 and the target deployment position via the fine-tuning direction, fine-tuning angle between the second sensing element 320 and the target deployment position, and the positional relationship between the optical sensing element 310 and the second sensing element 320.

[0063] Step D: Drive and adjust the optical sensing unit 300 to the target deployment position according to the fine-tuning direction and fine-tuning angle. The processing unit 500 can control the first motor 410 and the second motor 420 to drive the optical sensing unit 300 to move according to the fine-tuning direction and fine-tuning angle to reach the target deployment position.

[0064] In actual operation, Step C includes: confirming the included angle between the first sensing element 110 and the second sensing element 320 on a coordinate plane according to the first coordinate position and the second coordinate position, where this coordinate plane is parallel or perpendicular to the display surface of the display unit 200; confirming the fine-tuning direction and fine-tuning angle on this coordinate plane according to this included angle; and driving the optical sensing unit 300 to move to the target position on this coordinate plane according to this fine-tuning direction and this fine-tuning angle.

[0065] Specifically, in one embodiment, Step C includes,

[0066] Step C11: Confirm the first included angle a1 between the first sensing element 110 and the second sensing element 320 on the first coordinate plane xy according to the first coordinate position and the second coordinate position. The first coordinate plane xy is parallel to the display surface of the display unit 200.

[0067] Step C12: Confirm the first fine-tuning direction and the first fine-tuning angle on the first coordinate plane xy according to the first included angle a1; and

[0068] Step C13: Drive the optical sensing unit 300 to move to the first target position on the first coordinate plane xy according to the first fine-tuning direction and the first fine-tuning angle.

[0069] In one embodiment, step C further includes

[0070] Step C21: Confirm the second included angle a2 between the first sensing element 110 and the second sensing element 320 on the second coordinate plane yz according to the first coordinate position and the second coordinate position. The second coordinate plane yz is perpendicular to the display surface of the display unit 200.

[0071] Step C22: Confirm the second fine-tuning direction and the second fine-tuning angle on the second coordinate plane yz according to the second included angle a2; and

[0072] Step C23: Drive the optical sensing unit 300 to move to the second target position on the second coordinate plane yz according to the second fine-tuning direction and the second fine-tuning angle.

[0073] It should be noted that in actual operation, the order of steps C11 to C13 and steps C21 to C23 can be exchanged or either can be selected, without special limitation.

[0074] Please refer to Figure 6 , Figure 6 which is a schematic diagram of the optical sensing unit of the present invention. In the present invention, the optical sensing unit 300 has a circuit board 330, and the optical sensing element 310 and the second sensing element 320 are electrically arranged on the circuit board 330. The optical sensing element 310 can be a light sensor, a color sensor, etc. A connector 340 is provided on the circuit board 330. The connector 340 is used to connect to a power source and transmit electrical signals. The connector 340 can be connected to the processing unit 500 of the display device 1000. In this embodiment, the processing unit 500 includes a main board (IFBD) 510, and the connector 340 is communicatively connected to the main board 510 to transmit information such as the coordinate position of the second sensing element 320.

[0075] Please refer to Figure 7 and Figure 8 , Figure 7 which is a front view of another embodiment of the optical sensing unit of the display device of the present invention at the target deployment position, Figure 8 isFigure 7 Front view of the optical sensing unit in the storage position. In the display device 2000, the optical sensing unit 300 includes a first component 301 and a second component 302. The optical sensing member 310 and the second sensing member 320 are disposed on the first component 301. When the optical sensing unit 300 is in the storage position, the first component 301 is sleeved inside the second component 302; when the optical sensing unit 300 is in the deployed position, the first component 301 extends out of the second component 302. In this way, the storage space of the optical sensing unit 300 can be reduced, facilitating the storage and deployment of the optical sensing unit 300. In addition, when encountering a display device with a larger size, if the optical sensing unit 300 is to be deployed to the exact middle position, the size of the optical sensing unit 300 is relatively long, which is likely to cause the situation where the optical sensing unit 300 is not parallel to the display surface of the display panel 100 during deployment. In this embodiment, by designing the optical sensing unit 300 as a folding member, the situation or amplitude of fine-tuning the optical sensing unit 300 by the driving unit 400 to make it parallel to the display surface of the display panel 200 can be reduced.

[0076] For the control method of the display device and the optical sensing unit of the present invention, by providing a first sensing member serving as a reference reference point on the housing and a second sensing member on the optical sensing unit, when the optical sensing unit reaches the initial deployment position, the fine-tuning direction and fine-tuning angle of the optical sensing unit are confirmed according to the coordinate positions of the first sensing member and the second sensing member, and then the optical sensing unit is driven to the target deployment position by the driving unit according to the fine-tuning direction and fine-tuning angle, improving the precise positioning of the optical sensing unit and ensuring subsequent sensing and calibration results.

[0077] Of course, the present invention can also have many other embodiments. Without departing from the spirit and essence of the present invention, those skilled in the art can make various corresponding changes and deformations according to the present invention, but these corresponding changes and deformations should all fall within the protection scope of the appended claims of the present invention.
