Description

The present invention relates to, for example, an image display device that displays an image in space.

Normally, when performing road construction or traffic control on the road in the event of an accident, a stick is used to instruct the stop / progress of the vehicle. At night, the stick is made of hollow plastic, for example, to ensure visibility, and a bean ball or a light emitting diode is incorporated in the stick and used by lighting it. However, since the above-mentioned stop / progress instructions are given by changing the way the stick is swung and the support method, it differs slightly depending on the individual difference of the operator, and it is difficult to judge as an object that requires common recognition. There is a problem.

Also, in recent years, light-emitting sticks are often used to support events such as indoor concerts and various outdoor gatherings at night. As the light emitting stick, a small stick in which a substance that emits light by a chemical reaction is stored in a resin stick is often used, but there is a problem that if this stick is discarded after use, it causes environmental pollution. Further, there is a problem that light emission by a chemical reaction has a short light emission time and is difficult to reuse. Furthermore, simply waving a stick that is only emitting light is not interesting to liven up the support of the event.

Various techniques have been disclosed in order to solve the above-mentioned problems.

In Patent Document 1, a plurality of red and green light emitting diodes (LEDs) are linearly arranged in a stick and lit in red or green. In this way, the instruction is made easier to understand by the difference in color, such as stopping when the vehicle is lit in red and progress when the vehicle is lit in green. However, the instructions based on the difference in lighting color are not universally determined, and the technical concept of positive instruction display related to stop / progress is not disclosed. In addition, the fun of the lighting display used for cheering at the event is not taken into consideration.

Patent Document 2 discloses a technical idea of a message display toy that displays characters or pictures by utilizing the afterimage effect. The technical idea is that light emitting diodes (LEDs) are arranged along a rod-shaped stick body, the LEDs are blinked by a plurality of blinking patterns that blink the LED group, and the stick is shaken left and right to achieve a visual residual effect. It displays a picture or text. If this can be displayed well, it will be effective at the time of traffic control and events.

However, since the above blinking timing is performed by the built-in timer circuit, it is difficult to keep the reciprocating time and swing speed of the left and right swings of the stick constant, and depending on the swing method, the time error of the photoreceptor cells described later It will not be synchronized with the error time of, and the displayed characters will be interrupted, the back characters or characters will be jammed or stretched, and eventually it will not be possible to distinguish.

In Patent Document 3, as in Patent Document 2, the LEDs arranged in the longitudinal direction of the stick are read from the memory of the microcontroller chip to blink the character display data, and the characters are displayed by the visual residual effect by shaking the stick. The technical idea to be done is disclosed. However, the technical idea regarding the blinking timing is not clearly disclosed, and it is very difficult to match the speed and timing of swinging the stick as in Patent Document 2, inferring from the display of the clock generation circuit in the circuit block diagram. As described above, the time of the photoreceptor cells is out of sync with the error time, and the displayed characters are interrupted or become back characters depending on the swinging method, making it impossible to distinguish them.

Patent Document 4 is the same as the above in that the LEDs arranged in the longitudinal direction of the stick are read from the memory of the microcomputer to blink the character display data, and the characters are displayed by the visual residual effect by shaking the stick. However, in order to prevent the above-mentioned problems of character display, a technical idea of providing a timing starting point determination for controlling a timing schedule, a moving direction sensor for determining a timing length, and an acceleration sensor is disclosed. Although it is possible to prevent the characters from becoming back letters by these technical ideas, since the speed is determined by the acceleration sensor, the displayed characters may be missing unless the speed at which the stick is shaken is kept constant. Further, when the stick is shaken, if the shaking speed changes in the middle, the error time shifts, and the middle of the character may be stretched, clogged or distorted, making it difficult to read.

As described above, sticks incorporating a plurality of light emitting elements are widely used, but there are problems as described above. The present application is intended to solve these problems, and an object of the present application is to provide a video display device that is easier to see and functionally guarantees a conspicuous display for use at an event or the like. ..

In solving the above-mentioned problems, the inventor of the present application first conceived of utilizing the time error of photoreceptor cells (cell excitement sustaining effect). That is, in human photoreceptor cells, the photoreceptor cells become excited by the light stimulation of the photoreceptor cells, and the excited state continues even after the light stimulation disappears, causing a time error as if the perception time of the light stimulation continues. ..

By reading the light emission data from the memory based on the memory for storing the data and the angle information from the angle sensor and causing the light emission display unit to emit light, a time error of the photoreceptor's photoreceptor cells is caused, and the light emission display unit is moved. As a result, there is a means for the time error of the photoreceptor cells to continue and a certain amount of information to be visually displayed.

By providing such a configuration, the display unit is moved while sequentially displaying a part of the image to be displayed, and the image is displayed in space as a visual continuum utilizing the above-mentioned time error effect.

As a second aspect of the present application, in the first aspect, the light emitting display unit may be composed of a plurality of light emitting elements arranged substantially linearly on a long substrate. Alternatively, as a third aspect of the present application, in the first aspect, the light emitting display unit may be configured by a long strip-shaped light emitting display.

As a fourth aspect of the present application, in the first aspect, there is a character display mode in which lighting data is extracted from the memory based on the angle information from the angle sensor to light the light emitting element, and the light emitting element is fully lit regardless of the angle. It may be possible to switch between the all lighting modes to be displayed. Alternatively, it may be possible to switch between a mode in which characters and images are displayed by shaking the stick left and right due to the time error effect of photoreceptor cells, and a full lighting mode in which the light emitting display unit is constantly lit or intermittently lit.

As a fifth aspect of the present application, in the fourth aspect, the type of characters and / or patterns that can be displayed in the character display mode and the type of lighting color and / or blinking in the all lighting mode may be selected. .. Alternatively, a select switch may be provided so that the type of display character or video display pattern can be selected in the character / video display mode, and the lighting color or blinking type can be selected in the full lighting mode. Further, a select switch may be provided so that the type of display character or video display pattern can be selected in the character / video display mode, and the lighting color or blinking type can be selected in the full lighting mode.

As a sixth aspect of the present application, in any one of the first to fifth aspects, the light emitting display unit is equipped with light emitting elements on both the front and back sides of the elongated substrate, and both sides of the elongated substrate are substantially simultaneously. , Or it may be possible to light in different modes. In addition, a light emitting element or display board is equipped on both the front and back sides of an elongated substrate to light one side as a character or video display mode and operate the other side as a full lighting mode, or both sides are a character or video display mode or both sides are fully lit. It may be operated as a mode.

As a seventh aspect of the present application, in the second aspect, a light emitting diode that emits different light to one element may be used as the light emitting element. Further, as an eighth aspect of the present application, in any one of the first to fifth aspects, the memory data stored in the memory can be written and / or rewritten from the outside for writing and rewriting. The interface unit of the above may be further provided.

Further, a connector may be provided on the stick so that the data in the memory can be rewritten by connecting to an external personal computer or mobile phone.

As a ninth aspect of the present application, in any one of the first to sixth aspects, the stick-shaped housing may be further provided with an acoustic microphone.

As a tenth aspect of the present application, in the ninth aspect, any one or more of the image pattern / image display color / image character may be changed by rhythm analysis of the acoustic signal from the microphone.

As an eleventh aspect of the present application, in any one of the first to eighth aspects, the stick-shaped housing may be further provided with an image projection device.

As described above, conventionally, traffic control and support at an event have been performed by using a light emitting body or a light emitting stick in which a light emitting element is enclosed so that the light emitting body can be visually recognized even at night. For example, in the case of traffic control, in the past, a signal for stopping / progressing a vehicle was sent by holding or swinging the light emitting stick, but by using the image display device according to one aspect of the present invention, As well as emitting light, you can give specific instructions by shaking the stick as a character display mode and displaying characters such as (tomare) and (recommendation) in the space using the time error effect, so the vehicle side It can be clearly seen, and the safety of traffic control can be further improved. Further, by using the multicolor display unit, for example, if (Tomare) is displayed in red and (Recommended) is displayed in green, the visibility can be further improved.

On the other hand, with the display stick as described in Patent Documents 2 and 3, the displayed characters may be missing or become back characters. Further, in Patent Document 4, if the speed at which the stick is shaken is not constant, the characters may be chipped or the characters may be stretched or shrunk in the middle, making it difficult to visually recognize the characters. Then, there is an effect that the entire character can be accurately visually displayed (the meaning of "visual display" will be described later) only by shaking the stick at a certain angle or more to make the error time almost constant.

Further, taking support at the time of an event as an example, by using the image display device according to one aspect of the present invention, it is possible to shake the stick as a full lighting mode in which the entire stick is made to emit light, and the content of the event can be changed. You can also do new support such as changing the emission color. Furthermore, by changing to the character display mode, comments such as (wonderful!) And (Ganbare) or a portrait of the supporting talent can be visually displayed and supported, so that communication between the event player and the spectator can be further increased. Furthermore, as with traffic control, changing the emission color according to the text comment will produce a new effect.

In the example in which the video display device according to one aspect of the present invention is used for cheering, the display characters are rewritten by the user via a personal computer or a mobile phone, so that the characters that are most suitable for the situation of use are visually recognized. It is possible to display, change the emission color and the emission sequence, and there is an effect that different cheering methods can be performed even if a plurality of people are using the same image display device according to one aspect of the present invention.

In addition to the above effects, as an application of the image display device according to one aspect of the present invention, if a double-sided display unit of a long substrate is arranged, one side is set to a character display mode and the other side is set to a full lighting mode, and both sides are lit. For example, at the event venue, the player can be encouraged by displaying characters, and the audience can be excited by turning on all the lights. Of course, a new effect can be expected even if both sides are set to the character display mode or the full lighting mode.

Further, as an application of the image display device of one aspect of the present invention, the user's ID (individual identifier) can be displayed as an image to prove the identity of the individual user, and can be used as a substitute for an admission ticket at an event, for example. .. In addition to the above-mentioned spatial display by time error, the same ID projection can be performed by the image projection device mounted on the tip of the stick-shaped housing.
