1. 핀 포인트를 이용한 디스플레이 소자1. Display element using pin point

The display element (or display device) using the pin point includes a motor. The display system according to an exemplary embodiment of the present invention may control (or display) a three-dimensional (3D) stereoscopic image by controlling a motor using a sensor.

The pins included in the display element may come out or enter through the motor and the sensor, and may have a pin depth. The pin depth may refer to the length of the pin in a predetermined direction from the body of the display element and the length of the pin exposed to the outside of the display element. Alternatively, the pin depth may indicate the degree to which the pin enters the body direction of the display element based on the maximum length of the pin exposed to the outside of the display element. That is, the pin depth of the pin represents the distance from the reference point (eg, the tip of the pin that emerges the most) to the pin point of the pin. Through a pin having a pin depth, a three-dimensional (3D) three-dimensional feeling may be expressed.

The pin included in the display element may have a rod shape or a shaft shape. The pin point represents the head (end) of the pin.

The display device may use a sensor to control the motor drive. The display element may drive the pin in a depth form to move the pin back and forth. By using pin points of a plurality of pins having a pin depth, an image having a three-dimensional effect may be expressed. Many pins having depth information are recognized, and through these pins, images having a three-dimensional feeling and a flat feeling can be expressed.

The display system converts the input image into a black and white image, and moves the pin of the display element back and forth according to the depth of the black and white image. The display system uses the length of the back and forth pins to represent the image.

The display element may use a motor driving method. In detail, the motor driving method may process the pin depth by recognizing the marking spot through a sensor (eg, an infrared sensor). Alternatively, the motor driving method may process the pin depth by using the rotation speed of the motor.

The motor moves the pin so that the pin has the depth obtained through image processing. The display element may use the sensor to check whether the motor is driven by a value corresponding to the obtained depth. For example, the display device may detect marking spots using an infrared sensor to check whether the motor is driven by a desired value. As another example, the display element may detect the number of revolutions of the motor using a sensor (eg, a sensor connected to the motor) to check whether the motor is driven by a desired value. Hereinafter, a sensor for detecting the rotation speed of the motor is referred to as a 'motor rotation sensor'.

The display system may configure a screen having a three-dimensional effect by moving pins of the plurality of display elements. The pin point of the pin with depth provides a three-dimensional (3D) effect in three dimensions.

The image processor black and white shades the red-green-blue (RGB) pattern of the input image, and generates data having a depth value by applying a gray step to the black and white shaded image. The sensor may check the number of marking spots or the number of rotations of the motor based on the data having a depth value, and thus the pin length (or pin depth) may be determined. An image of RGB color is converted into a gray scale image, and a gray step (or depth range) is applied to the grayscale image to generate depth information (or depth data) of each pixel. Can be. Based on this depth information (or depth data), the length of the pin (or pin depth), the number of motor turns, and the number of marking spots can be checked. The depth information of the pixel may correspond to the pin depth of the pin.

Information related to the control of the motor drive may be previously stored (or registered) in the operating device or the storage device. The pins of the display element move forward and backward based on information previously registered in the operating device or the storage device.

When the expression of one image is completed, the expression information of the corresponding image may be stored. The stored representation information can be used in the representation of another image and can be used as a correction value of the depth information (or depth data).

The pin points of the pins of the display element may constitute a screen in the form of dots.

Hereinafter, a method of constructing (or expressing) a screen having a three-dimensional (3D) three-dimensional effect using the above-described new display element will be described. Specifically, a method of automatically mapping a pin depth value to an image level (eg, a black and white level) and controlling the movement of the pin by using a motor and a sensor so that the pin has the mapped pin depth will be described.

1 is a view showing a cross section of a display element using a pin point according to an embodiment of the present invention. In FIG. 1, (a) shows a left side cross-sectional view of the display element DPE, and (b) shows a front cross-sectional view of the display element DPE.

The display device DPE may include a pin SHA, an infrared sensor 100, and a motor 113.

The pin SHA may be in the form of a rod or a shaft. A portion of the pin SHA is included in the display element DPE, and the pin SHA moves up and down.

The motor 113 moves the pin SHA up and down. The motor 113 may be connected to the pin SHA through the gear GR.

The infrared sensor 100 detects the marking spot MS. The infrared sensor 100 may be disposed at a fixed position. Here, the plurality of marking spots MS are located in the marking region MR. The marking area MR moves in the direction of movement of the pin SHA together with the pin SHA when the pin SHA moves. The infrared sensor 100 may detect the marking spot MS passing through the reference area R3. For example, when the pin SHA moves downward, the marking area MR also moves downward, and the infrared sensor 100 passes through the reference area R3 downward in the marking spot MS. ) Can be detected. Since the number of detected marking spots MS corresponds to the depth of the pin SHA, it may be determined whether the pin SHA has moved by a desired value. That is, the depth of the pin SHA may be determined based on the number of detected marking spots MS. On the other hand, the infrared sensor 100 may be replaced with a sensor for detecting the number of rotation of the motor 113. Through the sensor for detecting the number of revolutions of the motor 113, it may be confirmed whether the pin SHA has moved by a desired value. Since the rotation speed of the motor 113 corresponds to the depth of the pin SHA, it may be confirmed whether the pin SHA has moved by a desired value. Hereinafter, for convenience of description, an embodiment of the present invention will be described by taking the case where the display element DPE includes the infrared sensor 100 as an example. The method described below may be similarly applied to the case where the display device DPE includes a sensor for detecting the number of rotations of the motor 113.

Areas R1a and R1b represent areas for knowing the starting point and end point, area R2 represents a stopper for preventing the pin SHA from moving over a certain section, and area R4 represents the pin SHA. ) Shows the fixing frame for fixing.

FIG. 2 is a diagram illustrating a structure of a marking spot corresponding to a pin depth of a display element according to an exemplary embodiment of the present invention.

The number of marking spots MS located in the marking region MR may be adjusted according to the depth range. Here, the depth range represents a range of depth values that the pin SHA may have and may be adjusted. For example, when the depth range is large, as illustrated in FIG. 2A, many marking spots MS may be located in the marking region MR at narrow intervals. In another example, when the depth range is small, as shown in FIG. 2B, relatively few marking spots MS may be located in the marking region MR at a wide interval.

The display element DPE moves the pin SHA through the motor 113, and determines whether the marking spot MS passes through the reference area R3 by the number corresponding to the input depth value through the infrared sensor 100. When the number of marking spots MS corresponding to the input depth value passes through the reference region R3, the driving of the motor 113 is stopped. Through this, the pin SHA has a pin depth corresponding to the input depth value.

The display element DPE may move the pin SHA forward and backward (or up and down) through the motor 113 according to the input depth value, and detect the number of marking spots MS or the motor 113. The depth of the pin SHA (or the length of the pin SHA exposed to the outside) may be adjusted according to the number of rotations of the pin SHA.

3 is a diagram illustrating pin movement of a display device according to an exemplary embodiment of the present invention. 3 is a front sectional view of the display device DPE.

As illustrated in FIG. 3, the display element DPE moves the pin SHA forward and backward (up and down) through the motor 113.

4 shows a front sectional view of three display elements DPEa, DPEb, DPEc arranged in series.

Each of the display elements DPEa, DPEb, and DPEc drives the

motors

113a, 113b, and 113c based on the input depth value to move the pins SHAa, SHAb, and SHAc, and the pins SHAa, SHAb, and SHAc. The marking spots MS moving together are detected through the

infrared sensors

100a, 100b and 100c, and it is determined whether the number of detected marking spots MS corresponds to the input depth value.

Each of the display elements DPEa, DPEb, and DPEc may quickly move the pins SHAa to SHAc by the number of marking spots MS corresponding to the input depth value through the speed control of the motors 113a to 113c.

For example, when the display element DPEa receives the depth value 1, the pin SHAa is moved based on the input depth value 1. Through this, the pin SHAa may have a pin depth corresponding to the input depth value 1. For another example, when the display element DPEb receives the depth value 3, the pin SHAb is moved based on the input depth value 3. Through this, the pin SHAb may have a pin depth corresponding to the input depth value 3. As another example, when the display element DPEc receives the depth value 9, the pin SHAc is moved based on the input depth value 9. Through this, the pin SHAc may have a pin depth corresponding to the input depth value 9. 4 illustrates a case in which the speeds of the motors 113a to 113c or the moving speeds of the pins SHAa to SHAc are 10. As a result, as illustrated in FIG. 4, the depth of the pin SHAc is the largest and the depth of the pin SHAa is the smallest. As illustrated in FIG. 4, as the pin SHA enters the body direction of the display element DPE, the pin SHA has a greater pin depth.

5 is a diagram illustrating a method of checking a marking spot by a display device according to an exemplary embodiment of the present invention. In Fig. 5, (a) shows before the pin SHA moves and (b) shows after the pin SHA moves. 5 illustrates a case in which 10 marking spots MS are included in the marking region MR.

When the display element DPE receives the depth value 3, the pin SHA is moved downward. When the pin SHA moves, the marking spot MS of the marking region MR also moves. At this time, the infrared sensor 100 detects the marking spot MS passing through the reference area R3. The display device DPE determines whether the number of detected marking spots MS corresponds to the input depth value 3. The display device DPE stops the movement of the pin SHA when the number of detected marking spots MS corresponds to an input depth value 3. As a result, pin SHA has a pin depth corresponding to an input depth value of 3.

As illustrated in FIG. 6, a plurality of display elements DPEa, DPEb, DPEc, and DPEd may be arranged in series. Each display element DPEa to DPEd includes pins SHAa, SHAb, SHAc, and SHAd.

Meanwhile, the plurality of display elements DPEa to DPEd may be arranged in a different pattern from that of FIG. 6.

A three-dimensional image may be expressed through the pin points of the pins SHAa to SHAd having the pin depth.

FIG. 7 is a view showing various types of pin head members that can be applied to the pins of the display element according to the embodiment of the present invention.

Various types of pin headdressing members may be applied to the pin SHA. Through this, various productions are possible.

In FIG. 7, (a) shows the front sectional drawing of the fin SHA of a general form. No additional pin headdressing member is applied to the SHA pin of the general type.

FIG. 7B shows a front sectional view of the fin SHA including the pin headdressing member HE1. The pin head decorative member HE1 may have a spherical shape or an ellipse shape.

In Fig. 7 (c) shows a front sectional view of the fin SHA including the pin headdressing member HE2. The pin head ornament member HE2 may have a spherical shape or an ellipse shape, and may include lighting (eg, light emitting diode (LED) lighting). The pin SHA may be a pin head ornament member HE1, HE2. Can be inserted in

On the other hand, replacement of the pin headdressing members HE1 and HE2 is possible.

Meanwhile, the pin head decorative elements HE1 and HE2 may include a touch sensor, a human body sensor, an input sensor, or the like.

A screen having expandability may be configured through the pin head decorative member applied to the pin SHA.

8 is a diagram illustrating a method of applying a spherical pin head decorative member to a pin of a display device according to an exemplary embodiment of the present invention. Specifically, FIG. 8 is a diagram showing a cross section of the pin headdressing member HE and the pin SHA.

The pin headdressing member HE may have a spherical shape. The pin headdressing member HE has a space for the insertion of the pin SHA. The pin SHA can be inserted into the pin headdressing member HE.

The display device DPE includes an infrared sensor 100, a control module 110, a motor 113, a power supply unit 120, and an input output controller (IO) controller 117.

As described above, the infrared sensor 100 detects the marking spot MS.

The control module 110 controls the detection of the infrared sensor 100 and the driving of the motor 113. In detail, the control module 110 may include a sensor logic unit 111, a motor controller 112, a logic processing unit 114, a data processing unit 115, and an input / output unit 116.

The sensor logic unit 111 counts the marking spots MS detected by the infrared sensor 100. For example, when the pin SHA is moved downward by the motor 113, the marking spot MS of the marking area MR is also moved downward, and the infrared sensor 100 is downward. The moving marking spot MS is detected, and the sensor logic unit 111 counts the number of detected marking spots MS. Since the number of marking spots MS finally counted corresponds to the depth of the pin SHA, it may be confirmed whether the pin SHA has moved by a desired value.

The motor controller 112 controls the motor 113. In detail, the motor controller 112 may control the direction (forward and reverse directions) and the speed of the motor 113. The display system may express a video through the speed control of the motor 113.

The motor 113 may be a direct current (DC) motor, an alternating current (AC) motor, a servo motor, a stepper motor, a geared motor, or the like.

The logic processor 114 controls the infrared sensor 100 and the motor 113 based on various input values according to the logic. The logic processor 114 integrally controls the motor controller 112 and the sensor logic unit 111. The logic processor 114 transmits a motor driving command to the motor controller 112 according to the counted number of marking spots MS. For example, the logic processor 114 may instruct the motor controller 112 to stop driving the motor 113 when the counted number of marking spots MS corresponds to a target value.

The data processor 115 converts the data received from the input / output unit 116 into executable data for the logic processor 114.

The input / output unit 116 receives data or outputs data through the IO controller 117. In more detail, the input / output unit 116 may support an interface for allowing the operating apparatus 130 to control the display device DPE through a universal serial bus (USB). The input / output unit 116 supports scalability to use a wireless network (eg, Wi-Fi, Bluetooth low energy (BLE), etc.).

The IO controller 117 is an interface device (or interface module) capable of controlling data received from the operating device 130. The logic of the control module 110 may be controlled, executed, or updated by the operating device 130 communicating with the control module 110 (eg, USB communication, wired or wireless network communication, etc.) via the IO controller 117. have.

The power supply unit 120 receives power (eg, AC power, built-in battery, or USB power) to supply power to each component (eg, the control module 110) of the display device DPE. The power supply unit 120 may be included in an external device different from the display device DPE.

The operating device 130 operates the display device DPE. The operating device 130 may process logic for the control module 110. In detail, the operating device 130 may communicate with the control module 110 of the display device DPE by wire or wirelessly through the IO controller 117. The operating device 130 may execute or update the control module 110. The operating device 130 may be a personal computer (PC).

The operating device 130 may include a controller 131, an upload module 132, an external interworking module 133, and an image processor 140.

The controller 131 generates matching data for each control module 110 (or matching data for each display element DPE, matching data for each motor 113, and matching data for each pin SHA). Here, the matching data for each control module 110 may include a position value (coordinate value) of the display element DPE or the control module 110 and a depth value of the pin SHA controlled by the control module 110. Can be.

When the depth data generated by the operating device 130 is transferred to the display device DPE, the display device DPE may match the received depth data with the number of marking spots MS. The depth data generated by the operating device 130 may be matched to a multidimensional array per pin SHA. If the control module 110 of the display device DPE controls only one motor 113 (ie, If the control module 110 and the motor 113 are in a 1: 1 relationship, the controller 131 may generate matching data for each motor 113. Here, the matching data for each motor 113 may include a position value of the motor 113 (or pin SHA) and a depth value of the pin SHA connected to the motor 113. Meanwhile, a plurality of motors 113 may be controlled by one control module 110 (that is, the control module 110 and the motor 113 have a 1: N relationship). This is described in detail with reference. The controller 131 may include a control program.

The upload module 132 transmits logic processed data (eg, logic processed matching data) to the control module 110 through the IO controller 117 for use by the control module 110.

The external interworking module 133 supports API (application programming interface) interworking for external linkage.

The image processor 140 converts the input image into a black and white image, and generates data representing depth by leveling the black and white image. In detail, the image processor 140 may generate depth data for each pixel (or depth data for each region) of the black and white image. Alternatively, the image processor 140 may divide the black and white image into a predetermined number (eg, the number of all motors 113) of divided images (or divided sections and divided regions), and generate depth data for each divided image. For example, when the total number of motors 113 included in the display system is 1200 (= 40x30), the image processing unit 140 divides the monochrome image into 1200 (= 40x30) divided images, and divides the image. Star depth data can be generated. Here, each of the 1200 divided images may correspond to each of the 1200 motors 113. Meanwhile, the image processor 140 may divide the input image into a predetermined number of divided images before converting the input image into a black and white image.

The depth data generated by the image processor 140 may be data indicating directly the pin depth of the pin SHA or indirectly indicating the pin depth of the pin SHA.

The image processor 140 may generate data for controlling or operating the control module 110, the infrared sensor 100, and the motor 113. The controller 131 may generate matching data for each display device DPE (or matching data for each control module 110 or matching data for each motor 113) by using the data generated by the image processor 140. . The image processor 140 will be described in detail with reference to FIG. 11.

A plurality of display elements DPE is installed. For example, the plurality of display elements DPE may be arranged in an array form MxN. Each display element DPE includes a pin SHA and a motor 113 for movement of the pin SHA.

The operating device 130 processes logic for the display device DPE or the control module 110 of the display device DPE.

The image processor 140 may convert the input image into a black and white image, generate a black and white level data by black and white leveling the black and white image, and generate a pin depth value for each motor 113 using the black and white level data.

In detail, the image processor 140 may include an image loading unit 141, a black and white converter 142, a black and white level converter 143, a depth converter 144, and a matching processor 145.

The image loading unit 141 loads and analyzes the input image.

The black and white converter 142 converts the image received from the image processor 141 into a black and white image.

The black and white level converting unit 143 extracts the RGB color from the black and white image, and converts the extracted RGB color to the gray scale according to the set depth range (eg, 1 to 10). For example, when the total number of motors 113 included in the display system is 1200 (= 400x300), the black and white image may be divided into 1200 (= 40x30) divided images, and the monochrome level converting unit ( 143 may extract an RGB color from each of the divided images and convert each of the extracted RGB colors into a black and white level.

The depth converter 144 converts the monochrome level value received from the monochrome level converter 143 into depth information (eg, pin depth value). For example, the depth converter 144 may convert a black and white level value of each divided image into a pin depth value.

The matching processor 145 matches each of the pin depth values received from the depth converter 144 to each of the display elements DPE. In detail, the matching processor 145 may match the pin depth value with the position of each control module 110 (or the position of each pin SHA), the infrared sensor 100, and the speed of the motor 113. . For example, the matching processor 145 may match the pin depth value of each divided image to the display element DPE (or the control module 110, the motor 113, and the pin SHA) corresponding to each divided image. Can be. The matching processor 145 may match the pin depth value to the pin SHA based on the position of each pin SHA.

The matching processor 145 may include a position matching unit 146 and a depth matching unit 147.

The position matching unit 146 matches the position value of each control module 110 to each control module 110. For example, when the display elements DPE are arranged in an M × N matrix, the position matching unit 146 may be connected to each of the display elements DPE (or the control module 110, the motor 113, and the pin SHA). Position coordinates (m, n) can be matched. The position matching unit 146 may match each divided image to each display element DPE (or the control module 110, the motor 113, and the pin SHA).

The depth matching unit 147 determines the pin depth value and the speed and direction of the motor 113 for each display element DPE (or the control module 110, the motor 113, and the pin SHA), and displays each display. The device DPE (or the control module 110, the motor 113, and the pin SHA) is matched. For example, the depth matching unit 147 matches the pin depth value of each divided image to the display element DPE (or the control module 110, the motor 113, and the pin SHA) corresponding to each divided image. can do. The speed and direction of the motor 113 may be set for each motor 113.

A plurality of display elements DPE may be arranged in a matrix structure. That is, as illustrated in FIG. 12, the pin array in which the fins SHA of the plurality of display elements DPE are arranged in a matrix structure may form a screen.

The image processor 140 converts the input image into a monochrome image when the image including the 'KK' character is input, and divides the monochrome image into the number of display elements DPE (or the number of pins SHA). The image is divided into (divided sections), the black and white level value of each divided image is converted into a pin depth value, and the pin depth value of each divided image is transferred to the display element DPE (or pin SHA) corresponding to each divided image. Can match.

The control module 110 of each display element DPE moves the pin SHA through the motor 113 based on the pin depth value received from the operating device 130. For example, each display element DPE may move the pin SHA until the number of marking spots MS corresponding to the received pin depth value is counted. As a result, the pin SHA of each display element DPE has a pin depth corresponding to the input depth value. On the other hand, when the display element DPE receives the position coordinate value together with the pin depth value, the display element DPE determines the pin depth value for itself among the received pin depth values by using the received position coordinate value. Can be used.

As illustrated in FIG. 12, through the pin SHA having a pin depth, the letter 'KK' may be expressed in three dimensions.

A plurality of display elements DPE may be arranged in a matrix structure. That is, the pins SHA of the plurality of display elements DPE are arranged in a matrix structure to form a screen.

In FIG. 13, (a) shows a method of expressing the letter 'K' in an intaglio, and (b) shows a method of expressing the letter 'K' in an intaglio.

In FIG. 13A, the plurality of pins SHA corresponding to the letter 'K' has a larger pin depth value than the other pins SHA. That is, the number of pins SHA corresponding to the letter 'K' enters more than the rest of the pins SHA.

In FIG. 13B, the plurality of pins SHA corresponding to the letter 'K' have a smaller pin depth value than the other pins SHA. That is, the number of pins SHA corresponding to the letter 'K' comes out more than the rest of the pins SHA.

The display system may display an image by adjusting the illumination intensity of the pin SHA instead of the pin depth of the pin SHA. In this case, the pin head of the pin SHA includes illumination (eg, LED illumination).

As illustrated in FIG. 14, the plurality of pins SHA corresponding to the letter 'K' may have a greater illumination intensity value than the remaining pins SHA. Or conversely, the plurality of pins SHA corresponding to the letter 'K' may have a smaller illumination intensity value than the remaining pins SHA.

The display system may adjust various lighting intensities of the plurality of pins SHA, thereby representing various images having a three-dimensional effect.
