Abstract:
A two-dimensional color display device allowing selective generation and display of a broad range of colors, said device comprising:a plurality of luminous elements each having luminous wavelengths different from each other collectively disposed on a flexible substrate in an N.times.M matrix arrangement, said flexible substrate being periodically thinned so as to facilitate rolling of the device, at least one of emission intensity and a luminous color of each of said luminous elements being separately controllable from those of other ones of said luminous elements, said controllability being conducted on the basis of selective variation of at least one of a time series pulse intensity and a width which is applied to said luminous element, such that each luminous element emits a desired emission intensity and luminous color, and a collective emission intensity and luminous color of adjacent ones of said luminous elements effect display of a desired color, and one of said luminous elements being controlled so that the emission intensity thereof is different from the emission intensity of at least one other luminous element when said one and said at least one other luminous element emit light, and wherein N and M are each an integer not less than 2; andsignal wiring connected to said luminous elements, said signal wiring being arranged in a matrix.
