Abstract:
A driver for a color display having an array of pixels, the pixels each being comprised of a first color element, a second color element, and a third color element, wherein said first color element, said second color element and said third color element are each adapted and configured for producing different color with respect to each other; the first color element being coupled to a first set of color terminals only, the second color element being coupled to a second set of color terminals only, and the third color element being coupled to a third set of color terminals only, the driver comprising:an input circuit including a first set of input terminals, a second set of input terminals, and a third set input terminals, the first set of input terminals receiving first color signals indicative of first gray scales for the first color element, the second set of input terminals receiving second color signals indicative of second gray scales for the second color element, the third set of input terminals receiving third color signals indicative of third gray scales for the third color element; a control circuit coupled to the input circuit, the control circuit providing a first set of analog signals in accordance with the first gray scales only to the first set of color terminals, the control circuit providing a second set of analog signals in accordance with the second gray scales only to the second set of color terminals, and the control circuit providing a third set of analog signals in accordance with the third gray scales only to the third set of color terminals; and wherein said first set of analog signals, said second set of analog signals and said third set of analog signals are separate sets of analog signals and are selected from independent sets of analog voltages where each of the independent sets is dedicated to a single color and associated with only one of said first, second and third sets of color terminals.
