Abstract: The present invention is a compact personal digital assistant (PDA) and cellular telephone with foldable dual-sided display. By utilizing flexible display technology, both a PDA and a cellular telephone are incorporated into one device. In a closed state, in one embodiment, the present invention corresponds to the form used for typical cellular telephone use (e.g., candy bar size). In an open state, in one embodiment, the present invention corresponds to the form used for typical PDA use by providing an enlarged viewing area. The present invention provides the benefit of two distinct devices in one device by allowing for common operations and functionality without compromising the respective form factor of either device.

Abstract: A method and an apparatus for color conversion of n-bit color data to m-bit color data (where n is greater than m). New color data bytes and original color data bytes are compared for a current pixel and a previous pixel immediately preceding the current pixel, so that any change in the original color data is reflected in the new color data. This is done by changing the current pixel when a match of the new color data bytes and a mismatch of the original color data bytes occurs. The invention is especially useful for maintaining contrast between text and background.
