BRIEF SUMMARY
DESCRIPTION
1. Technical Field
The present invention relates to an n-dimensional type scanning display method and apparatus, by which even an observer moving at a high speed can see the display content by utilizing the after-image effect of eyes and which can display a large image by a small number of display elements.
2. Background Art
As the conventional display method for an advertisement on a shop front or in a show window or for an outdoor advertisement, there are generally adopted a method using a signboard comprising a painted iron sheet or a cut plastic material, a method in which a box is formed in the rear of a plastic or glass sheet on which a picture is drawn and an illuminator is arranged in the box, and a method using an electric sign board comprising a neon sign or LED. Recently, there have been used an electric news or Q-vision type display system of an improved large TV, liquid crystal TV or LED type such as a jumbotron.
However, according to each of these conventional display methods, the display is mainly directed to a standing man or a man moving very slowly, and therefore, the conventional methods involve a problem in that a man moving at a high speed in the vicinity of the display apparatus cannot see the display content. With recent increase of the speed of a vehicle and recent reduction of a space for construction of an advertising tower or the like, the necessity of a display apparatus in which the display content can be correctly seen even from a moving vehicle is increasing.
In the method using a signboard or neon sign, the display content such as a displayed letter or image cannot be changed at all or can hardly be changed. In contrast, in an electric signboard or a recently developed TV type display system, the display content can be easily changed, but the mechanism is complicated.
Moreover, development of a display apparatus having an enhanced advertisement-displaying function capable of attracting the attention of an ordinary passenger more easily than in the conventional technique is desired.
Under this background, it is an object of the present invention to provide a display apparatus, in which the display content can be seen and read even by a person who is on a vehicle moving at a high speed and a large image can be displayed by a small number of display elements.
DISCLOSURE OF THE INVENTION
The n-dimensional scanning type display method of the present invention is characterized in that in obtaining an n-dimensional image in a display apparatus having an (n-1)-dimensional display plane, by the display changeover operation of the display plane and the moving operation of one of the display apparatus and the moving member for the observation, the image scanning operation in the remaining one direction is accomplished.
According to the present invention, by moving one of the display apparatus and the moving member for the observation, an n-dimensional display image can be obtained in the (n-1)-dimensional plane by utilizing the after-image effect of an observer, and an image display equivalent to the image display attained in the conventional technique can be attained by a smaller number of display elements.
The n-dimensional display apparatus of the present invention is fixedly arranged in a moving passage of the moving member for the observation, and comprises a sensor zone detecting the passage of the moving member for the observation and putting out a movement information, a data-forming zone forming a display changeover control signal based on the movement information from the sensor zone and putting out display data, and a display zone having an (n-1)-dimensional display array zone constructed by many emission elements, which is arranged for receiving display data based on the display changeover control signal from the data-forming zone and changing over and displaying (n-1)-dimensional images in regular succession.
If the scanning operation in one direction is thus performed by the displacement of the moving member for the observation and the timewise change of d
