Abstract

<P>PROBLEM TO BE SOLVED: To solve the following problem: an extremely huge screen, for example a screen that can be viewed in the night sky by many and unspecified people, can not be constituted because the structure gets extremely heavy if pixels are mechanically connected as heretofore. <P>SOLUTION: In this system, each intellectual picture element makes self-judgement on the light to be emitted and emits light while controlling each position to some extent so as to make the intellectual pixel itself visually recognizable, thus huge characters, sentences, images can be displayed. An intellectual pixel group operation station operates and manages intellectual pixel groups, determines the light emission schedule of an intermittent light emitter equipped to the intellectual pixel corresponding to the character to be displayed, and transmits the schedule as display data to each intellectual pixel through a wireless circuit. According to the receiving timing of the display data, the time of each intellectual pixel is corrected and synchronized. Each intellectual pixel makes the intermittent light emitter emit light according to the light emitting schedule. This light emitting state is recognized, by a viewer viewing from a viewing point sufficiently far from the intellectual picture elements, as a character intermittently emitting light. <P>COPYRIGHT: (C)2008,JPO&INPIT

Description

The present invention relates to a method for displaying characters and images with irregularly arranged intelligent pixel groups.

There is a large-scale image display device as an image display device visually recognized by an unspecified number of people. Conventional image display devices are composed of a large number of pixels, which are mechanically coupled. Therefore, a huge image display device requires a huge structure.

When trying to create a very large screen, for example, when trying to construct a screen that can be seen by an unspecified number of people in the night sky, when the conventional pixels are mechanically coupled, the structure weight is huge. Therefore, it cannot be realized.

The present invention solves the above-mentioned problem, and each intelligent pixel controls the position of each of the pixels to some extent, and makes the intelligent pixel itself visually recognized by self-determining and emitting light to be emitted. Character, text, and image can be displayed.

That is, the first of the present invention is an intelligent pixel that flies outside the atmosphere.
This is a display method characterized in that intelligent pixels are visually recognized from the ground by means of intermittent light emission.

The second aspect of the present invention is an irregularly arranged intelligent pixel group that flies outside the atmosphere.
It is a display method characterized by displaying characters visible from the ground by means of intermittent light emission.

The third aspect of the present invention is an irregularly arranged intelligent pixel group that flies outside the atmosphere.
It is a display method characterized by displaying words that are visible from the ground by means of intermittent light emission.

The fourth aspect of the present invention is an irregularly arranged intelligent pixel group that flies outside the atmosphere.
The display method is characterized by displaying an image that can be viewed from the ground by means of intermittent light emission.

By configuring intelligent pixels with a plurality of pixel satellites arranged on the satellite orbit, an on-orbit screen that can be viewed from the ground can be formed, and a new display medium can be realized.

Hereinafter, embodiments of the present invention will be described with reference to the drawings. FIG. 1 is an explanatory diagram showing a satellite-based sky display system to which the present invention is applied. In the figure, 1 is an intelligent pixel and an intelligent pixel group, 2 is an intermittent light emitter mounted on the intelligent pixel, 3 is an intelligent pixel group operation station, 4 is a display data transmission step, and 5 is a time synchronization step. Show.

An intelligent pixel group 1-2 composed of intelligent pixels 1-1 equipped with an intermittent light emitter 2 is launched and arranged on a satellite orbit by a rocket or the like. These intelligent pixel groups are managed and controlled from the intelligent pixel group operation station 3 by wireless.

The intelligent pixel group operation station 3 determines the light emission schedule of the intermittent light emitter 2 that is installed in the intelligent pixel corresponding to the character to be displayed. The schedule is determined by predicting the placement of intelligent pixels from moment to moment. FIG. 2 is an explanatory diagram that schematically shows a light emission schedule when, for example, A, S, and T are displayed in order. The determined schedule is transmitted as display data 4 to each intelligent pixel via a wireless line. The time of each intelligent pixel is corrected and synchronized with the display data reception timing. (Time synchronization step 5)
Each intelligent pixel 1 causes the intermittent light emitter 2 to emit light according to the light emission schedule. An observer who sees this light emission state from a sufficiently distant observation point recognizes it as a light that emits light intermittently.

An intelligent pixel group capable of displaying a plurality of character strings at a time is arranged, and the character string is displayed in accordance with the movement of the intelligent pixel group, thereby allowing the observer to recognize the character string. FIG. 3 is an explanatory diagram schematically showing a light emission schedule in the case of displaying a character string ASTR in an intelligent pixel group capable of simultaneously displaying three characters, for example.

It is explanatory drawing which shows the artificial satellite utilization sky display system of this invention. It is explanatory drawing which shows the light emission schedule in the case of displaying in order of A, S, and T in simulation. It is explanatory drawing which shows the light emission schedule in the case of displaying in order with ASTR.
