Description

Technical Field

[0001] This invention relates to a stereoscopic display device with a per-pixel in-and-out structure and its control method, and more specifically, to a stereoscopic display device with a per-pixel in-and-out structure and its control method that can effectively provide dynamic, colorful, and stereoscopic visual three-dimensional information realized in X-axis, Y-axis, and Z-axis coordinates. Background Technology

[0002] Two-dimensional (2D) displays, as they are known to date, are a way of displaying information to a user by setting pixels on a flat or closed curved surface and transmitting data to those pixels.

[0003] Due to the fundamental (physical) limitations of space represented by two-dimensional mathematical X and Y coordinates, two-dimensional (2D) displays cannot accurately represent space in three dimensions (X, Y, Z). To overcome this problem, computer graphics technology has developed, and the images achieved through current computer graphics have reached a level where they are virtually indistinguishable from the scenery we actually see.

[0004] However, no matter how advanced computer graphics becomes, its expressive means cannot escape the two-dimensional medium of the image, thus limiting it to imitating two-dimensional representations of three dimensions. These limitations are particularly noticeable in the spatial coordinate, vector, and motion calculations frequently dealt with in mathematics and engineering. In the above example, although the object being processed exists in three dimensions, the current representation methods are limited to two-dimensional media, such as paper, pictures, or fixed three-dimensional models. Therefore, auxiliary projection techniques are currently used for representation. These techniques are used to represent three-dimensional points, lines, and quantities in two dimensions, or to express, calculate, and represent specific phenomena by creating models. In this process, the original characteristics of quantities and phenomena, such as size and direction, are distorted, making it difficult to represent and understand information, or only allowing for the acquisition of information about the current state within a fixed model.

[0005] To address this, Korean Patent Publication No. 10-2003-0039142 discloses a display device in which a display device and a driving device are respectively arranged in multiple units of a specified size. The multiple units constitute a display section for displaying data. The driving device is used to adjust the protruding length of the display device. By adjusting the height of the display device, the contrast of the data allocated to each unit is represented, thereby enabling the data to be displayed in three dimensions. However, the problem is that the driving device that controls the movement of the display section operates by a stepper motor. When stepper motors are set in hundreds of pixel units, the component cost of tens of millions of Korean won makes commercialization almost impossible.

[0006] Furthermore, Korean Patent Publication No. 10-2017-0004317, as another prior art, discloses a display panel that displays color using light-emitting diodes per pixel, comprising: a housing including a front surface perforated portion with two or more rows of equally spaced perforations along both the horizontal and vertical directions; a light-emitting portion including a light-emitting column, a lifting groove, and a lifting screw connecting portion, wherein the light-emitting column is a transparent or semi-transparent three-dimensional column shape, the lifting groove is formed from the ground of the light-emitting diode lamp, the light-emitting column, etc., and the lifting screw connecting portion is provided at the end of the lifting groove; and a lifting portion including a lifting screw, a lifting rotating gear, and a lifting adhesive portion, wherein the lifting screw has a spiral groove, and the lifting rotating gear is connected to the lifting screw. The system transmits rotational force, raising or lowering the lifting screws and lifting gears via the aforementioned lifting and attaching parts; a rotation drive unit includes an electric motor and a rotation gear; a control unit controls the color information of the light-emitting parts, the adhesion of the lifting and attaching parts, and the operation of the rotation drive unit via a processor; and a power supply unit supplies power. The problem is that, due to the characteristic of controlling the movement of each lifting screw using an electromagnet clutch, the light-emitting parts cannot be precisely moved. Moreover, when used continuously, the accumulated movement error of the light-emitting parts may prevent the accurate output of the required stereoscopic image. Furthermore, the input and output control can only control in one direction at a time, thus preventing the achievement of diverse and complex performance. Summary of the Invention

[0007] Technical issues

[0008] This invention proposes a new technology to solve many problems of the prior art. The problem to be solved by this invention is to provide a stereoscopic display device and its control method having a per-pixel entry and exit structure, which can realize the Z-axis coordinate by multiple fixed housing parts arranged separately in the X-axis and Y-axis coordinate planes and entry and exit housing parts connected to the fixed housing parts 100 and capable of linear movement, and display illumination of multiple colors to the outside of each entry and exit housing part, thereby providing dynamic, colorful, and stereoscopic visual information realized in three-dimensional X-axis, Y-axis, and Z-axis coordinates.

[0009] Furthermore, the present invention aims to provide a stereoscopic display device having a per-pixel entry and exit structure, wherein the fixed housing part and the entry and exit housing part are modularized and assembled in a motherboard slot for economical and convenient maintenance.

[0010] Furthermore, another problem to be solved by the present invention is to provide a stereoscopic display device having a per-pixel entry and exit structure, wherein the entry and exit distance can be accurately controlled by uniformly setting the starting positions of a plurality of entry and exit housings corresponding to each pixel.

[0011] Technical solution

[0012] As a specific means to solve the problems of the present invention described above, the present invention comprises a stereoscopic display device having a per-pixel entry / exit structure, characterized in that it includes: a fixed housing portion 100, which forms each pixel unit of the stereoscopic display by being coupled to a motherboard 10 having a plurality of slots 12, and includes inside a linear drive module 120, a printed circuit board 112 (PCB) mounted in the slots 12, and a distance detection module 130; an entry / exit housing portion 200, which is arranged around the fixed housing portion 100, coupled to the linear drive module 120 and moved, and whose movement distance is detected by the distance detection module 130; and a visual information output portion 300, which outputs color data transmitted from a computer to the upper region of the entry / exit housing portion 200.

[0013] Furthermore, the present invention is characterized in that the above-mentioned device further includes a control module 110, which controls the position of the housing part 200 or controls the visual information based on the visual information output part 300 through the linear drive module 120. The control module 110 includes: a microprocessor, disposed on the printed circuit board 112 (PCB) or the motherboard 10, which receives performance information (movement distance of the housing part, color data) from a computer; and a motor driver, disposed on the printed circuit board 112 (PCB), which controls the rotation direction of the motor.

[0014] Furthermore, the present invention is characterized in that the linear drive module 120 includes: a gear base 126 disposed inside the fixed housing portion 100; a drive gear 123 coupled to the shaft of the motor 121 and rotating thereon; a rack 124 disposed along the length direction on one side of the housing portion 200; and a driven gear 122 disposed on the gear base 126 and meshing between the drive gear 123 and the rack 124.

[0015] The present invention is characterized in that the distance detection module 130 includes: a sensor 132 disposed on the fixed housing portion 100 and connected to the control module 110; a point-type or line-type detection piece 134 disposed along the length direction on the entry / exit housing portion 200 corresponding to the sensor 132; and a low point detection portion 136 that detects the lowest height of the entry / exit housing portion 200 to initialize the position of the entry / exit housing portion 200 as a zero point (starting point). The sensor 132 detects the moving distance of the entry / exit housing portion 200 by detecting the detection signal of the detection piece 134, and the distance detection module 130 similarly sets the starting position of each entry / exit housing portion 200.

[0016] The invention is characterized in that the low point detection unit 136 is equipped with a switch 136c electrically connected to the control module 110 on the fixed housing 100, and makes physical contact with the switch 136c when the housing 200 descends to its lowest height. Alternatively, a second detection piece 136a is provided on the lower part of one side of the housing 200. When the housing 200 is at its lowest position, a second sensor 136b for identifying the second detection piece 136a is provided on the printed circuit board 112 (PCB) at the position corresponding to the second detection piece 136a.

[0017] Furthermore, the present invention is characterized in that the above-mentioned visual information output unit 300 includes a light-emitting diode (LED) module 310, which is electrically connected to the control module 110 and is disposed at the end of the fixed housing unit 100 for outputting red, green and blue (RGB) light sources.

[0018] Furthermore, the present invention is characterized in that the aforementioned visual information output unit 300 includes: at least one liquid crystal (LCD) panel 320 formed in the housing portion 200; a backlight 322 disposed in the housing portion 200 for outputting a light source to the liquid crystal (LCD) panel 320; a first image control board 324 disposed in the housing portion 200 for controlling the liquid crystal (LCD) panel 320 and the backlight 322; and a first cable 326, one end of which is connected to the first image control board 324 and the other end of which is connected to the control module 110 for transmitting image signals and power.

[0019] Furthermore, the present invention is characterized in that the aforementioned visual information output unit 300 includes: at least one organic light-emitting diode (OLED) / quantum dot light-emitting diode (QLED) panel 330, formed in the housing portion 200; a second image control board 332, disposed in the housing portion 200, for controlling the organic light-emitting diode (OLED) / quantum dot light-emitting diode (QLED) panel 330; and a second cable 334, one end of which is connected to the second image control board 332, and the other end of which is connected to the control module 110, for transmitting image signals and power.

[0020] The present invention is characterized in that the control method of the stereoscopic display device having a per-pixel entry / exit structure includes: a position initialization step S10, setting the zero point (starting point) of the entry / exit housing 200; a target position data receiving step S20, after setting the zero point of the entry / exit housing 200, the microprocessor receives a target position value from the computer based on the moving distance of the entry / exit housing 200; a position difference calculation and storage step S30, calculating the difference between the target position value and the current position value and storing it as a movement command value; and an entry / exit housing operation step S40, whereby the movement command value calculated based on the current position value and the target position value is greater than the target position value. When the value is "0", the in-and-out housing section 200 is protruded by making the motor of the linear drive module 120 work in the forward direction. When the value detected by the distance detection module 130 is the same as the movement command value, the movement of the in-and-out housing section 200 is stopped by making the motor stop working. When the movement command value is less than "0", the in-and-out housing section 200 is moved back by making the motor of the linear drive module 120 work in the reverse direction. When the value detected by the distance detection module 130 is the same as the movement command value, the movement of the in-and-out housing section 200 is stopped by making the motor stop working.

[0021] In this case, the present invention is characterized in that, in the above-mentioned position initialization step S10, at the time when the power of the control module 110 is turned on, the motor 121 performs reverse operation to lower the housing part 200. When the lowest point of the housing part 200 is detected by the low point detection unit 136, the motor 121 performs forward operation to raise the housing part 200. When the sensor 132 of the distance detection module 130 detects the uppermost detected piece 134, the motor stops working and the starting point of the housing part 200 is set.

[0022] The effects of the invention

[0023] According to the specific means used to solve the above-mentioned problems, the present invention provides three-dimensional visual information on the display screen by means of a plurality of fixed housing parts arranged apart in the X-axis and Y-axis coordinate planes and an in-and-out housing part connected to the fixed housing parts and capable of linear movement to realize the Z-axis coordinate. At the same time, each in-and-out housing part displays lighting of multiple colors, thus providing dynamic, colorful and three-dimensional visual information.

[0024] Furthermore, a unit module consisting of a fixed housing part and an inlet / outlet housing part corresponding to a pixel can be assembled in the slot of the motherboard configured on the X-axis and Y-axis coordinate plane. The unit module includes a printed circuit board (PCB), a sensor, and a drive device. Therefore, in the event of a failure, only the unit module can be easily replaced for maintenance, thereby significantly reducing manufacturing costs and ensuring price competitiveness.

[0025] Furthermore, the movement distance of the housing can be accurately controlled by a general motor, which facilitates adjustment of the displacement and can be used in multiple fields. It can also convey a lot of information through the expression of color and images.

[0026] Furthermore, the starting positions of multiple entry and exit shells corresponding to each pixel can be set in the same way, and the movement distance of the entry and exit shells can be accurately controlled, thereby providing effective visual information by displaying an accurate sense of three-dimensionality.

[0040] The present invention will now be described in more detail with reference to specific embodiments in the accompanying drawings. Throughout this specification, when any component is "connected" to another component, this includes not only "direct connection" but also "indirect connection" where another component is spaced between the two components.

[0041] Figure 1 A perspective view illustrating a preferred embodiment of the stereoscopic display device with a per-pixel in-out structure provided by the present invention. Figure 2 for Figure 1 Decomposed 3D diagram, Figure 3 This is a main cross-sectional view illustrating a preferred embodiment of the stereoscopic display device with a per-pixel entry / exit structure provided by the present invention. The present invention relates to a stereoscopic display device with a per-pixel entry / exit structure and its control method, which realizes the Z-axis coordinate by the linear movement distance of each entry / exit housing portion, and realizes the X-axis and Y-axis coordinates by the spaced arrangement of each entry / exit housing portion on a plane. Its overall structure includes: a fixed housing portion 100; entry / exit housing portions 200, which are attached to the fixed housing portion 100 and are movable; and a visual information output portion 300, which displays illumination of multiple colors to the outside of each entry / exit housing portion, thereby providing dynamic, colorful, and stereoscopic visual information realized in three-dimensional X-axis, Y-axis, and Z-axis coordinates.

[0042] First, the fixed housing 100 of the present invention forms pixel units in the X-axis and Y-axis directions of the stereoscopic display screen by being installed in the slot 12 of the motherboard 10. The slot 12 of the motherboard 10 is arranged on the X-axis and Y-axis coordinate plane and has a printed circuit board 112 (PCB), a linear drive module 120 and a distance detection module 130 inside.

[0043] The aforementioned motherboard 10 has multiple slots 12 for mounting housing portions 100 corresponding to each pixel unit on the X-axis and Y-axis coordinate planes of the stereoscopic display screen.

[0044] The aforementioned fixed housing portion 100 is formed by a polygonal or circular tube that is embedded at one end into the slot 12 of the motherboard 10. The fixed housing portion 100 supports the in-and-out housing portion 200 (described later) above the fixed housing portion 100 in a linear reciprocating manner, and is used to guide the in-and-out housing portion 200.

[0045] The motherboard 10, which is equipped with the aforementioned fixed housing 100, can be integrated with the entire plane (X-axis, Y-axis) of the stereoscopic display screen to form a whole, or it can be standardized and assembled to the required size according to a specified size.

[0046] The stereoscopic display device of the present invention includes a control module 110, which controls the position of the entry and exit housing part 200 or controls the visual information output based on the visual information output part 300 through a linear drive module 120.

[0047] The aforementioned control module 110 includes: a microprocessor, disposed on the motherboard 10 or printed circuit board 112 (PCB), which receives performance information from a computer (smartphone); a motor driver, which has an H-Bridge circuit built in for controlling the rotation direction of the motor; and a printed circuit board 112 (PCB), thereby receiving performance information from the computer, controlling the position of the housing part 200 (described later) via the linear drive module 120, and outputting control visual information via the visual information output part 300.

[0048] The aforementioned display information refers to information that a person can visually recognize when viewing the stereoscopic display device of the present invention. Specifically, it includes at least one of the following: the moving distance of the housing portion 200, color data displayed to the outside of the housing portion 200, or image data displayed to the outside of the housing portion 200.

[0049] The aforementioned printed circuit board 112 (PCB) is disposed inside the fixed housing portion 100, and a protruding terminal with a length longer than the fixed housing portion 100 is formed at its end. The terminal is grounded to the slot 12 of the main board 10 and receives control signals and power.

[0050] Furthermore, the microprocessor receives and processes (computation, control) the performance information provided by the computer via wired and wireless communication, such as... Figure 9 As shown, the motor driver receives signals in the microprocessor and controls the movement of the housing 200 by driving the motor 121 of the linear drive module 120 in a forward / reverse manner and controlling its on / off operation.

[0051] Figure 4 To illustrate the structural diagram of a linear drive module of a stereoscopic display device with a per-pixel entry / exit structure according to an embodiment of the present invention, the linear drive module 120 includes: a gear base 126 disposed on a fixed housing portion 100; a drive gear 123 coupled to the shaft of a motor 121 and rotating thereon; a rack 124 disposed along the length direction on one side of the entry / exit housing portion 200; and a driven gear 122 meshing between the drive gear 123 and the rack 124.

[0052] In order to convert the rotational driving force of the motor 121 into linear motion at an appropriate speed, the gear base 126 can be rotatably mounted at both ends of the driven gear 122 and installed inside the fixed housing 100 or on the printed circuit board (PCB) of the control module 110.

[0053] In this way, a large reduction ratio can be obtained through a simple gear assembly. In the simple gear assembly, the driving force of the motor 121 is transmitted to the driven gear 122 through the drive gear 123. This not only achieves miniaturization and weight reduction but also prevents reverse rotation, thereby maintaining the Z-direction position of the rack 124 entering and exiting the housing 200 and fixing it in the accurate position.

[0054] In this case, the distance traveled by the distance detection module 130 into and out of the housing 200 is detected, and the motor 121 is controlled to turn on / off based on the detection value of the distance detection module 130.

[0055] Figure 5 This is a structural diagram illustrating another embodiment of the gear base of the stereoscopic display device of the present invention. As shown, the gear base 126 is detachably attached to a printed circuit board (PCB), and the gear base 126 has a shape corresponding to the internal space of the fixed housing portion 100, so as to enhance the strength of the fixed housing portion 100.

[0056] Multiple driven gears 122 can be provided in the gear base 126, and the appropriate driving speed for entering and exiting the housing 200 can be controlled by the gear ratio.

[0057] Furthermore, the motor 121 may also be provided with a mounting groove 126a, which allows the motor 121 to be easily inserted and fixed, thereby preventing movement during operation and providing stable drive stability.

[0058] Figure 6 This diagram illustrates the structure of the distance detection module of the stereoscopic display device of the present invention. The distance detection module 130 includes: a sensor 132 disposed in the fixed housing portion 100 and connected to the control module 110; a dot-shaped or line-shaped detection piece 134 disposed along the length direction in the housing portion 200 corresponding to the sensor 132; and a low point detection portion 136 that detects the lowest height of the housing portion 200 to initialize the position of the housing portion 200 as a zero point (starting point).

[0059] Figure 6 Part (a) is a structural diagram showing the dot-type test piece 134. Holes are formed in the housing portion 200, showing the test pieces 134, including magnets, arranged in the holes at predetermined intervals. Figure 6Part (b) is a structural diagram showing the linear test piece 134, illustrating an embodiment in which a magnetic tape is attached to the inner circumferential surface of the housing portion 200.

[0060] Furthermore, the low-point detection unit 136 is a unit used to detect the lowest height of the entry and exit of the housing section 200, as shown in the reference. Figure 2 A switch 136c electrically connected to the control module 110 can be installed on the fixed housing part 100. When the housing 200 descends to the lowest height, the low point detection part 136 can physically contact the switch 136c and identify the lowest point position.

[0061] As another way, refer to Figure 3 A second detection piece 136a can be provided on the lower part of one side of the housing 200. When the housing 200 is at its lowest position, a second sensor 136b for identifying the second detection piece 136a is provided on the printed circuit board (PCB) of the control module 110 at the position corresponding to the second detection piece 136a.

[0062] On the other hand, the position initialization of the entry and exit housing 200 means that the position of the entry and exit housing 200 is configured as zero point before the control module 110 is transmitted performance information (movement distance of entry and exit housing, color data), that is, the starting point position. The starting point of the entry and exit housing 200 does not mean the lowest point of the entry and exit housing 200 identified by the low point detection unit 136, but rather means the position of the uppermost detected piece 134 identified by the sensor 132 of the distance detection module 130.

[0063] Therefore, in order to reduce the identification error of the detected piece by sensor 132 and improve accuracy, such as Figure 3 As shown, when the housing 200 is at its lowest point, preferably, the sensor 132 of the distance detection module 130 is positioned at a higher position than the uppermost detected piece 134 within the range that it does not recognize.

[0064] In this way, the starting position of each entry / exit housing part 200 is set in the same way by the distance detection module 130, and the movement distance of the corresponding entry / exit housing part 200 is accurately controlled according to the performance information transmitted to the microprocessor.

[0065] The housing portion 200 of the present invention is arranged around the fixed housing portion 100 at the top, and the protrusion length is controlled along the fixed housing portion 100 by the linear drive module 120.

[0066] The aforementioned in-and-out housing portion 200 is formed of a tube having the same cross-sectional shape as the fixed housing portion 100, and a rack 124 is mounted on one inner circumferential surface. The rack 124 meshes with the driven gear 122 of the aforementioned linear drive module 120.

[0067] Therefore, the aforementioned entry / exit housing section 200 controls the entry / exit distance along the fixed housing section 100 and realizes the Z-axis coordinate of the stereoscopic display screen through the operation of the linear drive module 120.

[0068] In this way, in the stereoscopic display device provided by the present invention, a unit module consisting of a fixed housing part and an inlet / outlet housing part corresponding to a pixel is detachably assembled in the slot 12 of the motherboard 10 arranged on the X-axis and Y-axis coordinate plane. Each inlet / outlet housing part 200 realizes the Z-axis coordinate by moving up and down, thereby providing dynamic and stereoscopic visual information.

[0069] Furthermore, the pixel unit module, which consists of the in-and-out housing 200 and the fixed housing 100, includes a control module 110, a linear drive module 120, and a distance detection module 130. In the event of a malfunction, only the unit module with the corresponding defective pixel can be replaced or repaired, thus significantly reducing maintenance time and costs.

[0070] Figure 7 To illustrate the structure of the visual information output section of the stereoscopic display device of the present invention, the visual information output section 300 of the present invention is used to emit illumination and output color data of the display information transmitted from the computer to the upper region of the housing section 200.

[0071] The aforementioned visual information output unit 300 outputs illumination by being formed from any one of a light-emitting diode (LED) module 310, a liquid crystal (LCD) panel 320, or an organic light-emitting diode (OLED) / quantum dot light-emitting diode (QLED) panel 330. The liquid crystal (LCD) panel 320 and the organic light-emitting diode (OLED) / quantum dot light-emitting diode (QLED) panel 330 can be collectively referred to as "display panels" and are not distinguished separately.

[0072] Reference Figure 7 In part (a), the aforementioned visual information output unit 300 includes a light-emitting diode (LED) module 310, which is electrically connected to the control module 110 and is disposed at the end of the fixed housing part 100 for outputting red, green and blue (RGB) light sources. It may also include a diffusion panel 312 made of transparent or semi-transparent material as needed, so that the light source formed in the end region of the housing part 200 and output from the light-emitting diode (LED) module 310 is displayed on the outside.

[0073] In this case, as shown in the figure, the LED module 310 can also be fixedly installed at the end of the fixed housing portion 100, and the LED module 310 can be installed on the upper side of the housing portion 200 and movably installed together with the housing portion 200.

[0074] Furthermore, as shown in the figure, the aforementioned diffusion panel 312 can be integrally formed in a portion of the end or upper part of the housing portion 200.

[0075] Reference Figure 7 In part (b), the aforementioned visual information output unit 300 includes: at least one liquid crystal (LCD) panel 320 formed in the end region of the housing portion 200; a backlight 322 disposed in the end region of the housing portion 200 and outputting a light source to the liquid crystal (LCD) panel 320; a first image control board 324 disposed in the end region of the housing portion 200 for controlling the liquid crystal (LCD) panel 320 and the backlight 322; and a first cable 326, one end of which is connected to the first image control board 324 and the other end of which is connected to the control module 110 for transmitting image signals and power.

[0076] The backlight 322 is formed in a columnar shape in the center of the interior of the housing 200 and outputs backlight source to the surrounding area.

[0077] Reference Figure 7 In part (c), the aforementioned visual information output unit 300 includes: at least one organic light-emitting diode (OLED) / quantum dot light-emitting diode (QLED) panel 330, formed in the end region of the housing portion 200; a second image control board 332, disposed in the end region of the housing portion 200, for controlling the organic light-emitting diode (OLED) / quantum dot light-emitting diode (QLED) panel 330; and a second cable 334, one end of which is connected to the second image control board 324 and the other end of which is connected to the control module 110, for transmitting image signals and power.

[0078] In this case, the aforementioned organic light-emitting diode (OLED) / quantum dot light-emitting diode (QLED) panel 330 is composed of a conventional high-quality display panel that does not require backlighting or has a compact and integrally formed backlight.

[0080] Furthermore, the aforementioned visual information output section 300 is provided in the aforementioned open hole 203 with a diffusion panel 312, a liquid crystal (LCD) panel 320, or an organic light-emitting diode (OLED) / quantum dot light-emitting diode (QLED) panel 330.

[0082] Figure 10 To briefly illustrate a block diagram of a control method for a stereoscopic display device having a per-pixel in / out structure according to an embodiment of the present invention, Figure 11 A block diagram illustrating the process of setting the starting point (zero point) for entering and exiting the housing section. Figure 12 This is a control flowchart illustrating the condition judgment process performed during the entry and exit of the housing in the working steps of the control method for a 3D display device.

[0083] The control method of the stereoscopic display device with a per-pixel entry and exit structure of the present invention mainly includes a position initialization step S10, a target position data receiving step S20, a calculation and storage step S30, and an entry and exit shell working step S40.

[0084] 1. Position initialization step S10

[0085] The position initialization step S10 of the present invention is a step of uniformly setting the starting point (zero point) position of all the entry and exit housing parts 200 on the plurality of fixed housing parts 100 mounted in the slot 12 of the motherboard 10, which is in accordance with Figure 11 The sequence shown is implemented.

[0086] At the time when the control module 110 is powered on, the motor 121 operates in reverse to lower the housing section 200. When the lowest point of the housing section 200 is detected by the low point detection unit 136, the motor 121 operates in the forward direction to raise the housing section 200. When the sensor 132 of the distance detection module 130 detects the uppermost detected piece 134, the motor stops working and the starting point (zero point) of the housing section 200 is set.

[0087] 2. Target location data receiving step S20

[0088] In the target position data receiving step S20 of the present invention, after setting the zero point of the above-mentioned entry and exit housing part 200, the microprocessor of the control module 110 receives the target position value based on the moving distance of the entry and exit housing part 200 from the computer, and receives the moving distance of the entry and exit housing part 200 as a numerical value.

[0089] 3. Calculation and storage of location differences (S30)

[0090] The position difference calculation and storage step S30 of the present invention is a step of calculating the difference between the target position value and the current position value and storing it as a movement command value. Here, the current position refers to the position value at the time of receiving the target position value when entering or leaving the housing 200.

[0091] As an example, when the target position value is "3" and the current position value is "1", the movement command value is calculated as "2" (3-1=2) and the motor 121 is driven in the forward direction. When the target position value is "1" and the current position value is "3", the movement command value is calculated as "-2" and the motor 121 is driven in the reverse direction.

[0092] 4. Steps for entering and exiting the housing (S40)

[0093] The entry / exit housing operation step S40 of the present invention is a step of calculating the current position and target position values ​​and moving the entry / exit housing part 200 by forward and reverse drive of the motor 121.

[0094] Specifically, refer to Figure 12 The control flowchart shown is based on three conditions. When the movement command value calculated from the current position value and the target position value is greater than "0", the motor of the linear drive module 120 is made to work in the forward direction to make the housing part 200 protrude. When the detection value of the distance detection module 130 is the same as the movement command value, the movement of the housing part 200 is stopped by making the motor stop working.

[0095] Furthermore, when the aforementioned movement command value is less than "0", the linear drive module 120's motor is reversed to cause the housing section 200 to move back. When the distance detection module 130 detects the same value as the movement command value, the movement of the housing section 200 is stopped by turning off the motor.

[0096] As an example, if the target position value is "3" and the current position value is "1", and the movement command value is calculated to be "2" (3-1=2), then the movement command value is greater than "0", so the motor 121 is driven in the forward direction. Furthermore, if the target position value is "1" and the current position value is "3", and the movement command value is calculated to be "-2", then the movement command value is less than "0", so the motor 121 is driven in the reverse direction.

[0097] Furthermore, after the aforementioned entry / exit housing operation step S40, when moving to the target position data receiving step S20 to receive a new target position value, the current position value of the target position data receiving step S30 is substituted with the movement command value, and the calculated value is used as the basis to execute the entry / exit housing operation step S40.

[0098] That is, in the above-mentioned target position data receiving step S20, the position of the housing part 200 before receiving the target position value is updated to the current position value and used as the reference value for the subsequent entry and exit control of the housing part 200.

[0099] Figure 13 To briefly illustrate the flowchart of the control method for the visual information output section of the stereoscopic display device having a per-pixel in-out structure, the control module 110 transmits color data received from the computer to any one of the light-emitting diode (LED) module 310, liquid crystal (LCD) panel 320, or organic light-emitting diode (OLED) / quantum dot light-emitting diode (QLED) panel 330 of the visual information output section 300, and outputs it to the outside through the upper region of the housing section 200.

[0100] The aforementioned visual information output unit 300 can be controlled independently of the operation of the housing 200, and can release illumination based on color data received from the computer even when the multiple housings 200 constituting the stereoscopic display screen are placed at the zero point position.

[0101] As described above, the most preferred embodiments of the present invention have been illustrated in the detailed description of the invention, but various modifications can be made without departing from the technical scope of the invention. Therefore, the scope of protection of the present invention is not limited to the above embodiments, but includes technical solutions equivalent to those described below.
