The present invention relates to an image display system using a light emitting device, and more particularly, to display various characters, graphics, etc. on a plane by rotating an array of light emitting devices one-dimensionally arranged while flashing according to a predetermined flashing program. The present invention relates to an image display system using a light emitting device.

Conventionally, there has been an apparatus for displaying an image such as a character or a graphic by rotating while flashing an array of a plurality of light emitting elements arranged one-dimensionally.

Such an image display device has been disclosed in Japanese Patent Laid-Open Publication No. Hei 6-214509 (name: a signal lamp for character display, filed date: August 10, 1992). This technique is described with reference to FIG. 1), a group of thermal light emitters 2 provided at the outer end of the substrate in parallel with the rotational axis, opposing switches 7 and 11 for detecting the passage of the substrate in the correct position, and the time of passage detection As the substrate is rotated, the light emitting diode (light emitting diode) has a means for forming letters and figures on the rotation trajectory of the substrate end so that the light emitter flashes according to a plurality of time schedules.

The signal lamp for displaying such characters consists of a plurality of light emitting diodes 2 in the form of an array at both ends of the rotating substrate 1, and rotates around the rotating shaft 4 connected to the support frame 3 and rotates. According to the rotation state of the substrate 1, that is, the light emitting diode 2 is microcomputered according to the point of time when the proximity switch 7 fixed to the lower end of the rotating substrate 1 is detected by the proximity switch 11 fixed to the bottom. By blinking according to the time schedule (10), characters, figures, and the like are formed.

In addition, the display device of U.S. Patent No. 5,818,401 (filed April 4, 1996), with reference to Figures 2a to 2c, is installed on the pedestal 10 and the pedestal 10 is composed of a vertical axis having two bearings And rotating the cylindrical display body 20, the plurality of light emitting lines 11-18 arranged on the outer wall of the display body 20 to display information when the main body rotates, and the cylindrical display body 20. A control circuit section 55 providing information on speed and display, a power supply section 60 configured in the pedestal 10 to supply power through the anode and cathode, and transparent and opaque gratings and strips, The toroidal grating portion (encoder) 30 including the photo interrupters 36 and 38 having the light receiving portion Rx and the light emitting portion Tx integrated therein is included.

Such a display device has a plurality of light emitting lines 11-18 formed at regular intervals on the outside of the display body 20, and the light emitting lines 11-18 are supplied under the control of the control circuit unit 55. As it is flickered by electric power, an opaque grating 32 is formed inside the toroidal grating part 30 that detects the flickering time of the light emitting lines 11-18, and the blank 35 periodically outward. And a strip 36, and the photointerrupters 36 and 38 having the light receiving portion Rx and the light emitting portion Tx integrally formed inside the grating portion 30 to determine the rotation cycle and the flashing cycle. It is.

In addition, the image display device and method using the light emitting device of the Korean Patent Publication No. 10-201551 (Application Date: April 10, 1996) registered and filed in the domestic applicants, as shown in Figure 3, the light emitting device ( A light emitting module (A) including a light emitting element array (12) arranged one-dimensionally, and a driving motor (14) for rotating the light emitting element array (12), the central control unit (26), There is a control module (B) that includes a local memory 16, a buffer memory 24, a buffer 22, an address and control logic generator 20 and an address mux 26 to control the light emitting module (A), In addition, in the image display apparatus using a light emitting device comprising a power supply module (C) for supplying power to the light emitting module (A) and the control module (B), it is rotated and faced with the light emitting device array (12) Photodiode 30 as light emitting means provided, phototransistor 32 and disk as light receiving means A disk-shaped encoder 34 having a plurality of holes 33 formed at regular intervals at the edges to turn on / off the light sent to the photodiode 30 and the port transistor 32 by each hole 33. ), And includes a position sensing device 18 for sensing the position of the light emitting element array 12.

The image display apparatus using the light emitting device rotates the light emitting module A including the light emitting device array 12 at a predetermined speed, and at the same time as the light emitting module A is rotated, the photo configured at the bottom of the light emitting module A. The diode 30 and the phototransistor 32 also rotate, and emit light by sensing a plurality of holes 33 formed in the disc-shaped encoder 34 fixed between the photodiode 30 and the phototransistor 32. The location information of the module (A) can be known, and this location information is input to the control module (B), and the control module (B) outputs an address with respect to a position and time for outputting image information for display. This is to display a two-dimensional image using the visual afterimage effect.

After detecting the rotation position in each fixed proximity switch, it is controlled by the microcomputer. Therefore, since the plurality of light emitting diodes in two rows must be flickered after sensing the rotation position of the rotating substrate in the pair of proximity switches, it is not easy to adjust the rotation speed. That is, one proximity switch for detecting the position of the rotating board is composed of one. As the rotating board rotates once, the plurality of light emitting diodes blink, and if the position is detected by the proximity switch, the LEDs blink sequentially according to the set time schedule. The light emitting diode was not suitable for displaying shaking or complicated information of the displayed image because the blinking cycle was not constant.

In addition, the display device of U.S. Patent No. 5,818,401 constitutes a cylindrical array of light emitting diodes, and blinks by detecting a flashing period of the light emitting diodes by detecting the strips of the toroidal grating portion (encoder) and the plurality of photo interrupters. It was made. Here, one of the photointerrupters senses the origin and the other one detects the strip of the lattice part, so that the LED arrays are flickered, but also one photo interrupter is used to match the flashing cycles of the plurality of LED arrays. There were many issues. Therefore, the displayed image may be shaken.

Next, in the case of Korean Patent Publication No. 10-201551, which is the applicant's registered patent, one light emitting device array is arranged on one rotating substrate to display various images by rotation of the rotating substrate. The problem of the position sensing device consisting of an encoder having a plurality of holes, a photodiode, and a phototransistor is that the shaking or blinking period of the displayed image does not coincide exactly.

In order to solve the above problems, by connecting each position sensor to a plurality of light emitting diode array, by detecting the origin of the encoder with the strip formed by the origin sensor to prevent the inconsistency of the shaking or blinking period of the displayed image An object of the present invention is to provide an image display system using a light emitting device capable of transmitting more clear and accurate information.

In addition, the present invention is connected to a communication port and a wireless communication modem to transfer the information data for the display of the image in the form of a wired or wireless image to a plurality of image display apparatus from a computer or means for transferring the image information Data can be transmitted and displayed at the same time, and the image display device can be configured in various forms to double the transmission effect.

The transparent window 115 is coupled to the fixing plate 101 by a fixing ring, etc., and is made of a transparent material on the front surface of the rotating plate 102. The transparent window 115 is an image displayed by the LED array units 103-106. This is to be displayed to the outside and at the same time to prevent the entry of foreign matter. The transparent window 115 is preferably made of a material that is not bent or broken easily.

The power supply unit 139 rectifies or directly supplies AC power applied from the outside, and converts the input AC power into DC power to supply DC power of a predetermined level, or to supply AC power as necessary. It is a direct supply. It is preferable that the power supply unit 139 be configured with a circuit for blocking and absorbing surge voltage and noise of the applied power.

The motor 131 is driven by the power applied from the power supply unit 139, and the motor 131 generates a rotational force capable of rotating the rotating plate 102 and the encoder 122. It is preferable to apply the motor 131 to generate a constant rotational force while having a predetermined rotational force.

6 is a detailed view of the encoder unit of the present invention, the encoder 122 is coupled to the fixed plate 101 is configured so that the position sensors 124-127 can rotate along the outer periphery of the encoder 122, the encoder ( The outer periphery of the 122 is composed of a strip 140 composed of the transparent portion 141 and the opaque portion 142 periodically, the strip 140 is a photodiode (Tx) and phototransistor which functions as a light emitting portion and a light receiving portion (Rx) is positioned so that the position sensors 124-127 integrally formed are formed at right angles (90 °). That is, the four position sensors 124-127 detect the strip 140 of the encoder 122 in the diagonal direction, and the position sensors 124-127 are transparent parts 141 and opaque parts formed on the strip 140. A pulse wave (square wave) is generated from 142. Of course, when four or more position sensors (the number of light emitting diode arrays 103-106 are formed in the same number), the strips 140 of the encoder 122 may be read at the same interval.

In addition, the origin sensor 123 is configured at the same position as the position sensors 124-127 to detect the origin bar 128 fixed to the fixed plate 101 and apply it to the CPU 150.

In the driving of the image display system of the present invention, the power supplied from the power supply unit 139 drives the motor 131, and the rotational force generated from the motor 131 decelerates the rotating pulley 135 via the belt 136. The rotating pulley 135 rotates the rotating plate 102 and the position sensors 124-127 through the rotating shaft 134. At this time, the rotating plate 102 and the position sensors 124-127 should be rotated to the correct center on the rotation axis 134, which is between the photodiode Tx and the phototransistor Rx of the position sensors 124-127. The encoder 122 must be positioned at the correct center so that the position sensors 124-127 can generate pulse waves by reading the strip 140 along the outer circumference of the encoder 122. In addition, the plurality of light emitting diode array units 103 to 106 configured in the rotating plate 102 may also display a clearer image when the center of gravity is the same.

Through this rotation, the LED array unit 103-106 can display a clear image without shaking through the accurate blink cycle and rotation cycle, and the display of the image can be seen by referring to the circuit diagram of FIG. .

First, the plurality of position sensors 124-127 from the encoder 122 generate pulse waves due to the detection of the periodic strip 140, and the generated pulse wave signals are input to the CPU 150.

The CPU 150 retrieves information data for displaying an image stored in the memory unit 152 based on the input pulse signal and outputs a control signal to the decoder 154 and the buffer 155. In addition, information data input from the outside is applied via the communication port 138.

The data decoded by the decoder 154 among the applied information data are respectively input to the plurality of light emitting diode blinking ICs 111-114 configured in the light emitting diode array units 103-106, and are supplied through the buffer 155. Shift clock signals are also input. In addition, the CPU 150 also inputs information data to the light emitting diode flashing ICs 111-114.

In this manner, the respective data input to the light emitting diode flickering ICs 111-114 are inputted to the latch register and the shift register in the light emitting diode flickering ICs 111-114 to flash the plurality of light emitting diodes D. The resistor R is for dropping the applied voltage.

Therefore, the group of light emitting diodes D connected to the respective light emitting diode flashing ICs 111-114 is flickered by corresponding information data.

In addition, the CPU 150 receives information data wirelessly from a remote place through the wireless communication modem 130 and is input to the LEDs for flashing LEDs 111-114 and applied through the encoder 122 and the buffer 155. Like the signal, the corresponding light emitting diode D blinks.

In FIG. 8, information data for displaying an image stored in the memory unit 152 is included, and the information data includes M1, M2, ..., M n / 4, M n / 4 + 1, ... M 2n / 4, M 2n / 4 + 1, ..., M 3n / 4, M 3n / 4 + 1, ..., M n-2, M n-1, Mn, where M is the memory Where n is the number of encoders and represents the number of pixels on the outer periphery. Therefore, the corresponding information is inputted to the shift registers of the plurality of light emitting diode flashing ICs 111-114 to flash the corresponding light emitting diode D like the sensor data and the shift clock signal.

In addition, in the image display system using the light emitting device of the present invention, an image in which the light emitting diodes 107-110 are blinking and displayed in the light emitting diode array units 103-106 will be described with reference to the examples of FIGS. 9 to 10.

9 and 10 are images when only one position sensor 124-127 is used, and FIGS. 11 and 12 are views when the position sensor 124-127 is mounted to each of the light emitting diode array units 103-106. The image that appears is displayed.

First, when the image of FIG. 9 and FIG. 11 are compared, FIG. 9 is a case in which the encoder is not centered. In the conventional case, such a phenomenon exists, the number of grids of the encoder is eight, and the light emitting diode array is two. If there is a slight gap between encoders as a whole, there is a problem that the whole screen is severely shaken.

That is, the pulse wave (square wave) formed at the upper end of the graph in FIG. 9 is a case where the center of the encoder is not exactly aligned, and the pulse wave below is a case where the center of the encoder is exactly coincident. In addition, in the case of displaying the letter "A", a part is displayed when the centers of the encoders do not coincide, b is a 1st light emitting diode group, c is a 2nd light emitting diode group, and the upper and lower lengths were shortened for display. It is a state.

In this way, even if the LED group matches exactly, the alphabet "A" can be seen to shake, which is displayed from the point where the pulse of each encoder rises, and the thin dotted line shows the On point of the first LED group. The thick dotted line is the On point of the second LED group, and the second LED group is turned on in advance and then turned off later or turned off later or turned off first and then turned off first. It can be seen that having.

However, in FIG. 11, two position sensors are used and two light emitting diode array units are used. It can be seen that the number of grids of the encoder is eight, the light emitting diode array is two, and the difference between the pixels and the center of the encoder are not aligned, but the letter "A" is not shaken.

It can be seen that the second LED group almost exactly coincides with the first LED group, so that there is no shaking of the displayed image.

As such, when each position sensor is mounted on the plurality of light emitting diode arrays, it can be seen that a clearer image is displayed without shaking than when only one is mounted.

In addition, FIG. 11 shows that the fourth grid of the encoder is different, and when there is only one position sensor, there is a shake in four places. The black bar (strip) in the upper part of the graph is the opaque part 142 of the encoder. For example, there are 32 opaque parts 142 and the pulse wave at the bottom is one position sensor. In the image displayed at -106, one shake can be seen in each LED array unit 103-106. That is, the rising point d of the fourth pulse wave of "S" in the first light emitting diode array unit, the rising point e of the fourth pulse wave of "A" in the second light emitting diode array unit, and the third light emitting diode array. It can be seen that the shaking occurs at the rising point f of the fourth pulse wave of "T" and the rising point g of the fourth pulse wave of "." In the fourth light emitting diode array unit.

However, in FIG. 12, when the fourth grid of the encoder is different and four position sensors are used, it can be seen that one location is wide and one location is narrowly displayed. That is, it can be seen that in the first to fourth light emitting diode array units 103 to 106, the third is smaller and the fourth is larger in the fourth grid.

Therefore, when the position sensors 124-127 are configured in each of the plurality of light emitting diode array units 103-106, the image displayed is such that the shaking of the human eye almost occurs. It can be seen that a much clearer image is displayed than when a position sensor is mounted.

13 to 16 illustrate various forms of an image display system using the light emitting device of the present invention. FIG. 13 shows four LED arrays 161 formed on a cylindrical image display unit 160. FIG. 14 shows four light emitting diode array parts 171 formed on a spherical image display device 170, and FIG. 15 shows four light emitting diode array parts 181 formed on a hemispherical image display device 180. FIG. 16 illustrates four light emitting diode array units 191 formed on a spherical image display device 190, and the pedestals 162, 172, 182, on the lower ends of the image display devices 160, 170, 180, and 190, respectively. 192 is formed.

Meanwhile, referring to the block diagram of FIG. 17 to utilize and apply an image display system using a light emitting device of the present invention, a plurality of image display units 212 and 213 are installed, and the image display units 212 and 213 are wired or Receives data about images wirelessly and displays corresponding images, and in the case of wireless, displays text or images using text message service operated by wireless communication network 208 or mobile network operator. In this case, it may be displayed by directly operating or receiving a recording medium 211 including an image from a personal computer or a portable computer connected to the wired communication network 210 through a communication port, and the data about the image may be produced and managed by a manager ( 206) is to produce the image data and output to the wireless or wired network, in the case of a wired line through a telephone line or a dedicated line It can connect.

In addition, the production and manager 206 collects the data of the information provider 200, the data of the central government 202 or the data of the informant 204, and produces the image data.
