ABSTRACT:
TECHNICAL FIELD
The present invention relates to a color display device which utilizes a plurality of luminous elements having luminous wavelengths different from each other and which is used for performing display of various size, large-sized display as well as small-sized display. Further, the color display device according to the present invention includes a color display device having a display portion which can be rolled.
BACKGROUND ART
Color display devices are used in color television sets, a variety of display lamps, large-sized color television sets, or the like, and are grouped into the color display devices of the cathode-ray tube system, of the liquid crystal system, and the like.
All the conventional color display devices, however, have disadvantages in that sensitivity is poor and a clear display picture cannot be obtained, and in that the device per se is large in size and the power consumption is large.
Further, in the conventional color display devices having display portions of the cathode-ray tube system as well as of the liquid crystal system, the display portion cannot be bent because of the limitations on the system, or because of the quality/material and shape of the display portion.
The present invention has been attained to eliminate the foregoing disadvantages in the conventional devices, and an object of the present invention is to provide a color display device in which a plurality of luminous elements having luminous wavelengths different from each other are used so that desired visible light is produced and displayed by combining light on the basis of time series pulses.
Another object of the present invention is to provide a color display device which can be bent.
DISCLOSURE OF THE INVENTION
In the color display device according to the present invention, a plurality of luminous elements having luminous wavelengths different from each other are disposed collectively so that display is performed while controlling the emission intensity and luminous colors of the luminous elements on the basis of time series pulses.
The luminous elements, for example, of three luminous colors, red, yellowish green, and blue, are disposed collectively at one point. In the case where color correction cannot be sufficiently performed, it is a matter of course that some luminous elements may be added to the three luminous elements.
If light emission diodes are used as the luminous elements, they are superior in performance, reliability, cost, life, etc., to any other kind of luminous elements. The light emission diodes can emit desired luminous colors by changing the kind of the material and impurity thereof.
That is, in the color display device according to the present invention, a plurality of luminous elements having luminous wavelengths different from each other are used so that desired visible light is obtained and displayed by combination of emitted light on the basis of time series pulses. Further, the color display device according to the present invention has such a function that the device itself or a display portion thereof can be bent by performing wiring in either the vertical direction or the horizontal direction by evaporation, plating, or the like.
