Abstract
A field-sequential color image display device receives red, green, and blue image data, and decomposes the received data into more than three monochromatic images. The monochromatic images may include at least two red, two green, and two blue images. Alternatively, the monochromatic images may include one white image and at least one red, one green, and one blue image. The monochromatic images are displayed sequentially, each monochromatic image followed by another monochromatic image of a different color. The increased number of monochromatic images alleviates the problem of color breakup.
Claims22
A field-sequential color image display device for displaying a color image by sequentially displaying monochromatic images of different colors, comprising:
- a data decomposing means receiving image data for three primary-color components of one full-color image, including one red component, one green component, and one blue component, and decomposing the received image data to generate one white monochromatic image, at least one red monochromatic image, at least one green monochromatic image, and at least one blue monochromatic image;
- and
- a display means coupled to said data decomposing means, displaying the monochromatic images generated by said data decomposing means sequentially, in a predetermined order.
A method of displaying a color image by displaying successive monochromatic images in different primary colors, said method comprising:
- receiving an image data corresponding to a full-color image, said image data containing information about plural picture elements, the information being an M-bit integer per picture element, the signal also containing information about three different primary color components of the full-color image;
- decomposing said image data to generate plural monochromatic images including N first primary color monochromatic images, N second primary color monochromatic images, and N third primary color monochromatic images, said first and second and third primary colors being different, N being an integer greater than one but not greater than M, said decomposing including dividing said M bits per picture element for each primary color component into N groups of bits, said dividing depending on the bits forming each individual M bits;
- and
- displaying said plural monochromatic images in sequence.

- decomposing said image data to generate more than three monochromatic images, wherein said monochromatic images include one white monochromatic image, one first primary component monochromatic image, one second primary component monochromatic image, and one third primary component monochromatic image;
- and
- displaying said generated monochromatic images sequentially.
