Description

Vibration Light Emitting Display Device {VIBRATION LIGHT EMISSION DISPLAY APPARATUS}

The present invention relates to a vibrating light emitting display device, and more particularly, to a vibrating light emitting display device capable of displaying two-dimensional characters in a space within a vibration width of the display bar by vibrating the display bar at a frequency sufficient to produce an afterimage effect.

Various displays such as optical fibers, light emitting diodes, liquid crystal displays, and the like have been developed for advertisement and promotion. In particular, with the development of high brightness and multi-color light emitting diodes, the development of display devices using the same is more prominent. Large rooftop billboards, subway signboards, product promotions and advertising signs are commercially available.

Conventional light emitting display devices displaying characters by a two-dimensional array require a plurality of light emitting diodes because a two-dimensional array structure of the light emitting diodes is required, and a circuit configuration and a control method for driving a plurality of light emitting diodes are complicated. In addition to the high price, the power consumption was disadvantageous.

Therefore, recently, devices for displaying two-dimensional images using the afterimage effect by rotating and vibrating the one-dimensional array structure of the light emitting diodes have appeared.

These apparatuses include a method and apparatus for displaying a light emitting diode using afterimage effect (Patent Publication No. 1995-25620), an image display apparatus and method using a light emitting element (Patent Publication No. 1997-71439), and a light emitting signal apparatus (Patent Publication 1999- 15809), an electronic display panel (Patent Publication No. 1999-46615) which is expressed in proportion to the speed.

In order to use the afterimage effect, a high speed rotation or a high speed reciprocating motion is required to display several to several tens of frames per second. However, the prior art discloses a structure mainly combining a motor and a mechanical power transmission mechanism to obtain a rotational force. With such a movement mechanism, it is very difficult to display several to several tens of frames per second for a long time. Therefore, since the number of frames per second is reduced, there is a problem that the expression of the displayed image is not very simple and beautiful because it does not exhibit sufficient afterimage effect.

In the case of using the original rotation of the motor, high-speed rotation is possible to obtain the afterimage effect, but since the space for the original rotation is required, it is difficult to miniaturize due to the problem of increasing the size of the product.

In addition, the reciprocating motion method using the motor takes a lot of load due to the conversion structure for converting the rotational force into the reciprocating motion, so that the power consumption is high and the power transmission structure is complicated, which makes it difficult to manufacture the compact.

An object of the present invention is to provide a vibrating light emitting display device capable of two-dimensional display of characters by the afterimage effect and small size by vibrating the display bar to the left and right at high speed using magnetic and elastic force to solve the problems of the prior art There is.

Another object of the present invention is to provide a vibration light emitting display device having low power consumption by vibrating a display bar using an electromagnet at high speed.

Another object of the present invention is to provide a vibrating light emitting display device capable of stable high-speed vibration by servo-controlling the vibration of the display bar in synchronization with the vibration frequency and phase of the display bar.

Another object of the present invention is to provide a vibrating light emitting display device which can display more characters in a limited display space by partially overlapping display dots, and can display more beautiful characters in the inclined direction.

Hereinafter, with reference to the accompanying drawings, it will be described in detail the present invention through an embodiment of the present invention.

1 is a perspective view of an exterior of a preferred embodiment of a vibration light emitting display device according to the present invention, and FIG. 2 is a diagram illustrating an internal configuration of FIG. 1. The housing 10 of the device of the present invention consists of a pedestal 12, a circuit board 14, and a cover 16. The circuit board 14 is vertically fixed to the pedestal 12. The cover 16 covers the circuit board 14 and is fixed to the pedestal 12. A circular lid 18 is detachably formed on the front surface of the cover 16. When the lid 18 is opened, the battery case 20 and the keypads 22 installed on the front surface of the circuit board 14 are exposed. A power keypad 24 is formed at the lower right end of the front cover 16. Keypads 22 include set keys, up keys, down keys, light keys, left keys, and the like. A long hole 16a is formed in the center of the upper surface of the cover 16 so that the display bar 26 protrudes through the long hole 16a.

On the upper end of the display bar 26, a vertical array of light emitting diode arrays 28 is formed. On the left and right sides of the long hole 16a of the cover 16, a wing 16b is formed to cover the display bar 26 when the display bar 26 moves to the rightmost and leftmost sides. Such a wing structure hides the display bar 26 visible at the left and right stop points, causing the illusion that the display characters are displayed in space. The display bar 26 is preferably made of a light material such as a printed circuit board for the electrical connection between the light emitting diode array 28 and the control circuit.

The electromagnet 30 is installed in the horizontal upper end of the circuit board 14 in the horizontal direction, and the movable bar or the display bar 26 that traverses the center in the vertical direction is rotatably installed to the left and right. The display bar 26 is fixed to the free end 32a of the elastic cantilever 32. In the portion extending from the lower end of the display bar 26 to the lower right end, a connector 26a for connecting the display signal supplied to the light emitting diode array 28 is provided. The connector 26a and the light emitting diode array 28 are electrically connected to each other by a printed circuit pattern formed on the display bar 26.

The elastic cantilever 32 has a fixed end 32b fixed at a lower end thereof to a central lower end of the circuit board 14. The elastic cantilever 32 is composed of a trapezoidal leaf spring. That is, the width of the free end 32a is narrower than the width of the fixed end 32b, so that the degree of bending from side to side can be better bent from the fixed end 32b to the free end 32a.

The position of the free end 32a of the elastic cantilever 32 is set so as to be spaced apart a predetermined interval from the lower left and the front part slightly forward than the upper and lower center parts of the electromagnet 30. A permanent magnet 34 is attached to the left side of the free end 32a, and a contactor 26a of the display bar 26 is disposed on the right side. The permanent magnet 34 and the connector 26a of the display bar 26 are arranged to be balanced left and right about the elastic cantilever 32.

The position detecting means 36 is installed at the upper right end of the rear surface of the circuit board 14. The position detecting means 36 detects the position of the display bar 26 by blocking light when passing through the blocking plate 26b provided on the display bar 26 by a photo coupler. The position detecting means 36 detects the change of direction from the forward movement of the display bar 26 to the reverse movement. That is, the display bar 26 is disposed between the position where the display bar 26 is moved to the left to the maximum and the left side of the display area 38.

As shown in FIG. 3, the directions of the magnetic poles of the permanent magnet 34 and the electromagnet 30 are arranged perpendicular to each other. When viewed from the front, the permanent magnet 34 has an upper surface of the N pole, the lower surface of the S pole, the electromagnet 30 has an S pole on the left side, the N pole on the right side.

Therefore, the S pole of the electromagnet 30 and the N pole of the permanent magnet 34 interact with each other so that the display bar 26 first starts to move toward the S pole of the electromagnet 30 at the initial startup. That is, when viewed from the front of the device, when current flows in the electromagnet 30, it first proceeds from the center A to the left B, that is, the forward direction FW. When the current flow is blocked in the electromagnet 30, since the force acts in the reverse direction (BW) by the restoring force of the leaf spring 32 bent to the left, it moves to the center A again. From the moment you pass the center A, you will continue to the right C, ie the reverse direction, by inertia. When the moment of inertia is zero, the current is supplied to the electromagnet 30 again, and now the magnetic force (mainly repulsive force) and the restoring force of the leaf spring 32 act on the permanent magnet, so the direction of movement is changed and proceeds to the forward direction, CA. Done. As described above, according to the present invention, the display bar 26 is driven to vibrate with a predetermined vibration width by driving the electromagnet 30 on and off every vibration period.

In one embodiment, the permanent magnet 34 is positioned downward from the upper and lower center of the electromagnet 30, so that the S pole of the electromagnet 30 and the N pole of the permanent magnet 34 face each other as it moves forward. As it increases, the interaction force increases. Therefore, the interaction force between the electromagnet and the permanent magnet becomes effective.

By this movement mechanism, the display bar 26 vibrates at a constant vibration period, and the characters are displayed on the appropriate display area 38 within the vibration width.

That is, in one embodiment of the present invention, the electromagnet 30 is driven during the forward movement (moving from the right to the left), and the character is displayed during the reverse movement (moving from the left to the right).

The circuit board 14 includes a controller for driving the electromagnet 30 and the light emitting diode array 38.

Referring to FIG. 4, the control unit of the present invention includes an input circuit 42 for inputting a detection signal of the position detecting means 36, a display driver circuit 46 for driving the light emitting diode array 28, and And an electromagnet driving circuit 44 for driving the electromagnet 30, a key input circuit 48 for key input, a memory circuit 50 for storing display data, and connected to each of the circuits. A microcomputer 40 for executing a program and a power supply circuit 52 for supplying a power supply voltage to each circuit portion are included. In addition, the control unit is connected to the microcomputer 40 temperature and humidity detection circuit 54 for detecting temperature and humidity, audio input and output circuit 56 for inputting and outputting voice, data input and output circuit for inputting and outputting data (58).

The input circuit 42 waveform-forms the signal detected from the position detecting means 36 and provides a detection pulse signal to the microcomputer 40.

The electromagnet driving circuit 44 drives the current supply to the coil of the electromagnet 30 on / off in response to the electromagnet driving signal provided from the microcomputer 40.

The light emitting diode array 28 includes eight light emitting diodes. Thus, it has a resolution of 8 lines vertically. The display driver circuit 46 inputs a display signal of 1 byte from the microcomputer 40 to drive the LED array on / off.

The memory 50 is a nonvolatile memory and includes an EEPROM or a flash memory. The memory 50 stores display data such as a display message.

The power supply circuit 52 rectifies the commercial alternating current and provides the operating DC voltages VDD and VC to each circuit portion. The power supply circuit 52 includes a backup battery 52a to hold time data and the like of the microcomputer 52 even when AC power is cut off.

The temperature and humidity detection circuit 54 detects and provides the ambient temperature and humidity to the microcomputer 40.

The audio input / output circuit 56 provides a voice signal to the microcomputer 40 through a microphone, and outputs a voice signal provided from the microcomputer 40 through a speaker.

The data input / output circuit 58 is connected to the outside, for example, a computer, to interface the data input / output to the microcomputer 40. The data input / output circuit 58 may be composed of a known serial input / output circuit or a wireless input / output circuit.

The microcomputer 40 is a one-chip microcomputer and includes ROM and RAM as system memory therein. ROM stores operation programs, display fonts, and so on.

The display area of the present invention is composed of 8 lines x 108 dots, as shown in FIG. Therefore, a total of 12 characters are displayed. Therefore, the display area of one molecule has a size of 8 lines x 9 dots. As shown in FIG. 6, each dot overlaps a portion with adjacent dots. Therefore, the same line is skipped one by one and the other line is not overlapped with each other, so that continuous dot display is possible, so that characters can be displayed smoothly without stepped deviation in the display in the inclined direction than the display in the horizontal and vertical directions. Beautiful characters can be displayed.

That is, in the two-dimensional fixed type light emitting diode display device, elements cannot overlap each other due to the physical structure of the light emitting diodes. Therefore, when displaying in the oblique direction, there is a problem that images are displayed in a staggered manner and the image or text display is not beautiful.

However, in the present invention, since the dots are displayed time-divisionally, it is possible to display the overlapping dots by partially overlapping them without being limited by the physical structure. Therefore, character display of 8 lines by 9 dots is possible in an area of 8 lines by 4 dots.

In general, in the two-dimensional fixed type light emitting diode display device, the ASC (AMERICA STANDARD CODE) II code cannot be displayed in the character display area of 8 lines x 4 dots. In the present invention, however, the ASC (AMERICA STANDARD CODE) II code can be displayed in the display area of 8 lines x 4 dots by the overlap dot structure as shown in FIG. The font of FIG. 7 according to the present invention is stored on the ROM of the microcomputer 40. The font of Fig. 7 includes an ASCII code, a kanji character for displaying the year and the day of the week, a special symbol, and the like. Although not shown in Figure 7, Hangul is also configured in a manner similar to a special symbol and stored on the ROM.

Referring to FIG. 8, the microcomputer 40 checks the power key input (100). If there is a power key input in step 100, check the starting frequency stored in the memory (102). The vibration cycle is set according to the identified starting frequency (104). The on / off point of the electromagnet is determined according to the set vibration cycle (106). The electromagnet is driven and vibrated at an on / off point determined for a predetermined time (108).

The start completion is checked (110). When the start is completed, the start program is terminated and returned. If the start is not completed, the time elapsed is checked (112). If a predetermined time elapses, the start frequency is increased. That is, the vibration cycle is reduced (114). It is checked whether the raised frequency exceeds the set threshold frequency (116). If it exceeds, it is determined that an abnormality has occurred and the start program is terminated and returned. If the threshold frequency is within the threshold frequency, the on / off time point is reset according to the reduced vibration cycle (118), and step 110 is performed.

When the on / off point of the electromagnet is determined by the start program, the microcomputer 40 executes the drive pulse generation program of FIG. The drive pulse program is an interrupt execution routine based on timing. The microcomputer 40 waits at a predetermined time interval (120), and if the timing interrupt is applied, increases the counter value (122) and checks the start completion (124). If the startup is completed, the counter value is checked (126). If the counter value is the set time, turn on the electromagnet (128) and perform step 120. If the counter value is off at step 126, the electromagnet is turned off (130) and step 120 is performed. In step 126, if it is neither on time nor off time, step 120 is performed.

In operation 124, the counter value is checked (132). If the counter value is a set vibration cycle, the counter is reset and operation 120 is performed. In step 132, if the counter value is not a vibration cycle, step 126 is performed.

10 shows a servo control program. The servo control program is an external interrupt execution routine by the position detection pulse. The microcomputer 40 waits for the position detection of the position detection sensor (140). If the position detection signal is detected, the microcomputer 40 determines that the current direction of the current display bar is the forward direction if the first pulse is detected (146) and checks the start completion. ). If it is the second pulse, it is determined that the progress direction of the display bar is in the reverse direction, the counter is reset (144), and step 140 is performed. Here, since the counter reset is a reset in normal operation, it is different from the counter reset at startup. In operation 146, the operation completion determination and setup routine is performed (148) and operation 140 is performed. If the operation is completed in step 146, it is checked whether or not the abnormal vibration (150), if the abnormal vibration stops the operation of the electromagnet for a predetermined time (152), and performs step 140. If the abnormal vibration is not detected in step 150, the on / off point of the electromagnet is set in the next vibration period (154), and step 140 is performed.

In the normal operation state, the electromagnet is driven in synchronization with the vibration frequency and phase of the display bar. That is, the on / off time of the electromagnet controls the on / off time of the electromagnet in the next period by calculating the on time and the off time from the vibration cycle of the display bar detected in the current period.

As described above, the vibration method by driving the electromagnet of the present invention is divided into a start mode and a normal mode. In the start mode, the vibration of the display bar is activated in accordance with the set fundamental frequency, and upon completion of the startup, the vibration of the display bar is servo controlled by the position detection.

Referring to FIG. 11, in normal operation, the counter is reset in response to the second pulse of the position detection sensor to start a new count. When the count value is on, the electromagnet is turned on to accelerate the forward progress of the display bar. If the value is off, the electromagnet is turned off to pass through the position detection sensor by inertial force. When the first pulse of the position detection sensor is detected, the time T1 until the second pulse is detected is checked, and when this time is detected within a certain deviation range compared to the time T2 detected in the next period, abnormal vibration If there is no, and it is different, it will be judged as abnormal vibration.

At start-up, when the time T1 and T2 are detected and detected within the set deviation range more than a certain number of times, the display bar is determined to vibrate with a constant vibration cycle, and the microcomputer sets the start-up completion.

Therefore, in the present invention, the electromagnet is driven during the forward movement to drive a constant vibration of the display bar, and the light emitting diode array is driven during the reverse movement to display the characters.

In response to the second detection pulse of the position detection sensor, the frame display program of FIG. 12 is activated. That is, the character display operation is started after the oscillation period of the display bar is stabilized, that is, the startup is completed.

First, while down counting the timer set to the time of the next display position (160) and checks the display position time of the display bar (162). If the timer value is zero at 162, it is determined that the current display bar has reached the display position, and the timer is set to the time to move to the next display position (164). After resetting the timer, data of the current display position in the frame memory is read out (166), and the display position counter is incremented by one (168). Subsequently, the light emitting diode array is turned on for a predetermined time by the read data and then turned off (170). After extinguishing, step 160 is performed.

In the left and right ends, the display bar is stopped at the time when the direction of movement is changed and passes at the fastest speed in the center. That is, since the movement speed of the display bar is changed non-linearly according to the position, the blinking period of the LED array must also be varied according to the display position of each dot. In other words, the blinking cycle is the shortest at the center, and the blinking cycle is longer toward the left and right. That is, the time division of the flashing period for 108 dots should be time-divided non-linearly corresponding to the passing speed of the display bar. In each flashing period, the on-time of the LED array must be the same in order to maintain the same brightness, so the off-time is set differently according to the dot position.

Therefore, the microcomputer counts the given timing at every display position to control the timing up to the next display position.

As such, when the frame display program is repeatedly performed for 108 dots, an image or text of one frame is displayed. By displaying such a frame display 9 to 16 times per second, it is possible to display a two-dimensional video by the afterimage effect in the display area.

The display position of the character is determined by the position of the font data to be copied to the frame memory. When the font data is copied to the frame memory, the animation time of the character can be obtained by appropriately changing the copy time and position.

The steel wire spring 63 is bent in a zigzag and has elasticity up and down. Therefore, it is lengthened vertically as it bends when moving from the vertical position to the left and right. An elastic adjustment screw 68 is installed at the lower end of the steel wire spring to adjust the elastic force. Therefore, it is possible to adjust the elastic force corresponding to the most preferable vibration period.

In FIG. 15, the display bar 26 is restored by the coil spring 64 connected between the lower end centered on the rotational axis 62a of the rotation lever 62 and the housing below the vertical axis of the rotational axis 62a. An elastic adjustment screw 68 is installed at the lower end of the coil spring 64 to adjust the elastic force. Therefore, it is possible to adjust the elastic force corresponding to the most preferable vibration period.

In FIG. 16, the display bar 26 is installed on the rotation shaft 62a of the rotation lever 62 so that the inner end is fixed to the housing, and the outer end 66a is spaced apart from the rotation shaft 62a by the rotation lever ( It is restored by a spiral spring 66 fixed to 62.

In the above-described embodiment, the vertical display bar is taken as an example, but the display bar may be bent at least once. For example, the light emitting diode array may be bent in a direction perpendicular to the vibration surface of the display bar, and the light emitting diode array may be attached to the bent portion. In this case, the display area is convex or concave.

In addition, the display area may be provided up and down by providing the light emitting diode array not only at the upper end of the vertical display bar but also at positions symmetrical with respect to the oscillation rotation axis.

In addition, the light emitting diodes may be installed not only on the front side but also on the rear side of the display bar, so that the display can be displayed on both sides.

As described above, the present invention vibrates the display bar from side to side by using a magnetic force acting between the electromagnet and the permanent magnet and a restoring force by the spring, and drives the light emitting diode array within the oscillation width of the display bar to display a variety of moving images and characters. It is possible to display with graphical effects. Therefore, the vibration device can be manufactured in a small size, and thus the product can be miniaturized, and power consumption can be reduced. In addition, in the present invention, by setting the display dots to partially overlap, more characters can be displayed more delicately in a limited space, and in particular, a display in an oblique direction can be displayed more finely, thereby displaying a beautiful image or characters. can do.
