ABSTRACT:
FIELD OF THE INVENTION
The present invention relates to a dummy magnifying display apparatus and more particularly, to a dummy magnifying display apparatus that can artificially obtain a screen of which size is larger than an actual screen.
BACKGROUND OF THE INVENTION
In recent years, an electronic display has played an extremely important role in the society of information, and has widely been used in various fields regardless of both the industrial fields and consumer fields. The electronic display converts an electric signal outputted from electronic equipment to an optical information signal visually recognized by human. There have been known displays, as an ordinary electronic display, such as a cathode-ray tube display (CRT), a plasma display (PDP), an electroluminescent display (ELD), a liquid crystal display (LCD) referred to as a receptor type, and an electrochemical display (ECD).
Also, in recent years, the needs of the society to a low profile and light display capable of being driven with low voltage as well as with low power consumption has zoomed while a large number of compact, light and power-saved displays have been developed in association with rapid progress in IC and LSI. Further, it has been strongly desired to develop a display capable of supporting abrupt increase of an amount of information to be processed. Especially, with progress in multimedia technology, the electronic display has increased in importance as an indispensable item for accessing cyber space, and a larger size of screen with higher resolution has been desired further more strongly.
However, an image transfer system in the conventional type of electronic display is based on a scanning line system for continuously transferring image data at preset resolution as well as with a preset number of scanning lines, and this conventional type of display can not basically support a case where a size of a screen is arbitrarily changed for changing the resolution (the number of display elements in the lateral direction) as well as the number of scanning lines (the number of display elements in the longitudinal direction), and for this reason, the idea itself that the size of a screen can arbitrarily be changed by a user is impossible to come up in maker's mind.
For example, even when the size of a screen is made larger and resolution (the number of display elements in the lateral direction) and the number of scanning lines (the number of display elements in the longitudinal direction) are increased, the resolution and the number of scanning lines of image data to be sent with the scanning line system remain the same, so that image display using the entire screen is impossible. Also, when an image is to be displayed, the image is resultantly displayed on a part of the screen corresponding to the resolution as well as to the number of scanning lines of the transferred image data. In other words, even when the size of a screen is made larger, resolution of an image to be displayed on the screen can not be made higher.
SUMMARY OF THE INVENTION
The present applicant has already applied for another invention as an invention for solving the problems described above (Japanese Patent Laid-Open Publication No. HEI 9-144296). The application can be referred to for further detail.
It is an object of the present invention to provide an effective screen display system based on the concepts underlying the invention having been applied for.
A dummy magnifying display apparatus according to the present invention forms with a first display unit with display elements arranged at a matrix to form a screen as well as with a second display unit having the same configuration as that of the first display unit and connected to the first display unit at an angle to form a screen. Then, the screen is repeatedly divided in the first display unit. A dummy display section obtained by extending the first display unit is provided on the second display unit, an image to be displayed on the dummy display section is displayed on the second display unit, and the screen is repeatedly divided taking into consideration a positional relation between the first display unit and the second display unit. Then, an image is displayed on a part or whole screen of the first and second display units by setting an address to each of the divided unit areas each time when the screen is divided, specifying this address, and giving display data to be displayed with a display element belonging to the specified divided unit area thereto. A control unit controls the operations described above.
A dummy magnifying display apparatus according to the present invention has a main display unit located at the front part inside a hall and also has seat display units provided on the rear surfaces of seats each facing the front part therein. Also, each of the seat display units displays thereon a part of an image to be displayed on the main display unit and matches the main display unit by repeatedly dividing a screen taking into consideration a positional relation between the main display unit and each of the seat display units. For this reason, a plurality of users can see an image in a large screen. Especially, the front seats and users seated therein are not seen from users seated in the rear side, which allows any user to fully enjoy images.
Other objects and features of this invention will become understood from the following description with reference to the accompanying drawings.
