Description

Improved charater displayer using no screen}

The present invention relates to an improved screenless text display device, and more particularly, to an improvement of a text display device that can be used for various purposes.

An apparatus for projecting and displaying in the air without using a wall screen is conventionally conceived as a configuration that has been extensively used.

It has a case in which a plurality of light emitting diodes or the like are arranged in a straight line, and causes each light emitting diode constituting a letter corresponding to the inside of the light emitting device to be emitted at a time interval, and the user shakes the light emitting body in the air at night. By using the sequential blinking of the light emitting diode constituting the corresponding character as the zoom and the afterimage effect of human vision, the character is displayed as if the character is scattered on the night air.

The screenless character display device having such a configuration has been conventionally used and used as various event props or indicator bars for traffic control.

However, the above conventional configuration is seen as having a number of problems.

First, it has a main control device that controls the blinking of the light emitting diode at a time interval and has only a single text message input thereto, and thus cannot be used for various purposes.

Normal characters are projected during one-way rotation from the right side to the left side, but when the driver moves in the opposite direction, flashing becomes impossible to read, thereby reducing the feeling of novelty.

Incidentally, as the size of the light emitting diodes increases, they tend to be exponentially expensive. When a large light emitting diode is used for projection at night, the unit price increases rapidly, making it difficult to apply realistically. In the case of using a light emitting diode, there are various problems that the light emitting area is small and it is difficult to achieve a predetermined purpose.

The improved screenless text display device of the present invention was devised in view of the problems of the conventional screenless text display device described above. Thus, the above-mentioned various problems are eliminated. The main object of the present invention is to provide a screen-less text display device having a configuration that can be distributed for various purposes such as organizing and emergency rescue.

The improved screenless character display device of this paper has been developed for decades and its basic principle has been used for various purposes. This technology is well known and does not belong to the right part of the present application. It's right. An improved screenless character display device of the present invention, to which the principles widely known from the prior art have been applied, will be described with reference to FIGS. 1 to 4.

1 to 2 show the basic shape of the improved screenless character display device of the present invention, but can be configured as a variety of shapes, of course, but only one exemplary configuration.

The upper half body (1) and the lower half body (2), which are long bar-shaped upper and lower separators made of an injection molded body such as plastic, are housed therein, and the circuit portion of the improved screenless character display device of the present invention assembled therebetween. The circuit board unit 3 is assembled to form a bar-shaped character display device D. As shown in FIG.

On the front of the upper half body 1, the display window 10 is configured as a protective cover body such as transparent plastic and fixed to the window opening 11. This display window 10 will have a unique configuration of the present invention to be described later.

On the central side of the upper half body 1, a power switch 12 for applying the operating power is formed as a pressing portion and pressed in cooperation with the button switch 31 fixed on the circuit board portion 3 so that the entire power supply is applied. It turns ON / OFF.

In the space G between the upper half body 1 and the lower half body 2, the circuit board unit 3 and a power battery B that can be charged, are stored, and the upper half body 1 and the lower half body are accommodated. The lower portion of the entire character display device D that the sieve 2 constitutes forms a handle R, and the display window 10 becomes an actual display portion.

The circuit board unit 3 accommodates a circuit in which the character display device D of the present invention is implemented, and specific circuits housed in the circuit board unit 3, which is the printed circuit board, will be described later.

More preferably, the rear half of the lower half body 2 houses a combination keypad K for inputting characters input from the character display device D to the circuit board section 3, LCD display (L), which displays the input characters, is mounted. In addition, the rotatable cover 21 may be mounted to protect the keypad K and the LCD display L from the outside.

The circuit board section 3 is a display section, in which light-emitting elements arranged in a straight line, particularly preferably light-emitting diodes LED1-LEDn, are arranged and fixed.

Therefore, the light emitting diodes LED1-LEDn of the circuit board unit 3 and the display window 10 of the upper half body 1 cooperate to form the light emitting character display unit.

The character display device D of such a configuration allows characters to be displayed in the air on the example circuit part of FIG. 3 and on the principle of FIG.

The overall circuit configuration has a driver circuit 100 for driving the light emitting diodes (LED1-LEDn) and the driver circuit 100 emits light by an operation signal of the microcomputer 200, which is preferably a control unit that is made to order by one chip or the like. The diodes (LED1-LEDn) will flash sequentially at intervals. In addition, the microcomputer 200 is connected to a data storage device 300 such as a memory and sends a character input from the input interface 400 to the microcomputer 200. Various types of character input devices may be configured in the input interface 400.

For example, a dip switch (DIP SW) for selecting a desired character by a combination of a memory card 500 in which a plurality of characters are input in advance and an on-off switch among the characters input to the memory card 500 ( 501).

For example, the name or cheering information of a famous singer is input to the memory card 500 in advance, and the switch array of the corresponding dip switch 501 is selected by an on-off combination to display the name of a specific singer or display the contents. Change it to allow selection.

As another example, as described above, the character displayed on the LCD display L is input by a combination input of the combination keypad K, or

Alternatively, the character value input as the communication interface 512 through the communication line 511 from the character input program such as the personal computer 510 may be stored.

The microcomputer 200 selectively blinks any one or several of the light emitting diodes (LED1-LEDn) corresponding to the dots constituting each character so that the input character value can be displayed on the air in a very short time. For example, after 4 ms, one or more of the light emitting diodes (LED1-LEDn) corresponding to the dots constituting the character portion are subsequently turned on.

4 illustrates the principle of this operation.

Since the human eye has an afterimage effect, a character that is lit after an interval of very short time (1/24 seconds or less) leaves an afterimage of the image formed by the dot portion of the previous character, and thus the image formed by the dot portion of the next blinking character. In combination with, it is recognized as a connected character. As shown in FIG. 4, if the text display device D of the present invention is shaken by hand in the air at night, if the microcomputer 200 lights up the letter A sequentially, the letter A is displayed on the night air. In the instantaneous lighting situation, the instantaneous light-emitting diodes (LED1-LEDn) along the AA line are dots forming part of the letter A as shown in the drawing on the right, and only the light-emitting diodes (LED2, 3-LED7) It turns on and the previous character image and the subsequent character image are combined to form the letter A.

Therefore, any character can be displayed in the air by a variety of combinations.

More preferably, a multi-color light emitting diode (LED1-LEDn) controlled by the microcomputer 200 emits a different color according to a voltage value, and the microcomputer 200 emits light by changing a sequential voltage value. By providing the diodes (LED1-LEDn), it is also possible to display characters of various colors. Actual use is shown in FIG. 7.

However, in the case of the above-described configuration, there is one important problem, that is, when the character display device D is shaken to one side, the normal character is projected on the air, but the character combination is rotated in the opposite direction. Does not blink, resulting in an unreadable character. In view of the above problems, in the present invention, as shown in FIG. 5, the mercury switch is placed in an appropriate space formed by the upper half body 1, the lower half body 2, and the circuit board unit 3 of the character display device D. FIG. This problem is solved by providing an operation direction detecting switch (DW) capable of detecting swinging and rotating directions of the back, and further adding a reset circuit unit 201 to the microcomputer 200.

That is, the mercury switch as the operation direction detecting switch (DW) is a mercury drop (M), which is a fluid metal, is accommodated in the glass tube (T), and the electrodes (t1, t2) are disposed at both ends, and the mercury switch rotates to either side. The silver droplet M is biased in one direction to turn on any one of the electrodes t1 and t2. As the operation of the operation direction detection switch DW, for example, when the character display device D is rotated from left to right, normal characters are displayed, and when the right direction is rotated from right to left again, the operation of the operation direction detection switch DW is performed. As a result, the characters in the microcomputer 200 may display other character combinations normally or display the reversed characters so that normal characters are projected on the air.

One of the other features of the present invention, as shown in Figure 6,

Of a combination of a display window 10 such as a transparent injection body fixed to the window opening 11 formed on the upper half body 1 and a light emitting diode LED1-LEDn disposed on a straight line on the circuit board part 3; It's about improvement.

In general, light emitting diodes (LED1-LEDn) are exponentially expensive as their price increases, and are used in a non-screen type character display device so that a user can project a character at a brightness and size desired by the user. LED1-LEDn) should be used,

Since a large number of light emitting diodes (LED1-LEDn) must be used, when a large sized light emitting diode (LED1-LEDn) is used, the price of the character display device D is greatly increased, thereby making it impractical.

In addition, as the size of the light emitting diodes (LED1-LEDn) increases, the required power greatly increases, so that the lifespan of the power battery B is extremely short.

This problem is usually, when the character display device (D) of the present invention is used by a large crowd or a fan in a large performance hall or stadium, etc., in view of the purpose of distributing it to the visitors and recovering it after use, the price improvement is important. It is a problem.

In the present invention to solve this problem, as shown in Figure 6,

The light emitting diodes LED1-LEDn on the circuit board portion 3 are small and upwardly in a radial cross-section or in a triangular shape as shown in the display window 10 connected to the light emitting diodes LED1-LEDn. It is good to make it possible to configure the enlarged light emitting area portion (S) and to fix the light emitting diodes (LED1-LEDn) on the lower surface. More preferably, in order to prevent the light source from leaking out to the side, a reflective surface such as a silver plated surface may be formed on the side surfaces S1 and S2 of the display window 10.

In this configuration, although the light emitting diodes (LED1-LEDn) are small, the light emitting light source is projected while being enlarged by the display window 10, thereby maximizing the light emitting area.

As described above, the improved screenless character display device of the present invention overcomes all the disadvantages of the conventional screenless character display device, which can be displayed at various costs at low cost. It can be widely used as a tool for organizing, arranging workshops, and props for various campaigns.
