    摘要: A color display has continuous areas of a single color covering a plurality of sub-pixel electrodes. Each sub-pixel of a given color has sub-pixels of the same given color disposed along at least two of its adjacent edges. Each area of a single color may cover a 2×2 array of sub-pixel electrodes. The colors used may be red/green/blue/white (RGBW), red/green/blue/yellow (RGBY), or orange/lime/purple/white

    摘要: A tetrachromatic color filter array comprises multiple pixels, each of which comprises first, second, third and fourth sub-pixels having first, second, third and fourth hues, P1, P2, P3 and P4 respectively, these first, second, third and fourth hues having first, second and third hue angles, h1, h2, h3 and h4 respectively. The hues of the sub-pixels such that h3 equals h1+(180°±10°) and h4 equals h2+(180°±10°) in the a*b* plane of the La*b* color space.

    摘要: A technique for optimizing or enhancing color images. Embodiments are disclosed for creating an enhanced color image, including the enhancement of perceived color uniformity. In a “dot-on-dot” registration scheme for producing color images, the dots need to be precisely superimposed on each other to provide optimum or enhanced images. The dot-on-dot registration produced by a single head thermal printer is generally acceptable, but a single head machine is very slow because multiple passes (reciprocation) are required to lay down multiple colors of dots. In a much faster multi-head or tandem thermal imaging system a serious problem of dot misalignment may cause moire patterns or other visual artifacts in the color images produced by dot patterns. A solution to this problem is disclosed herein which intentionally misregisters superimposed dots in a novel and particular manner to achieve image optimization. In a particular embodiment a first thermal print head has a first number of thermal elements energized at a first rate and a second thermal print head has a second number of thermal elements energized at a second rate. The numbers of thermal elements and rates of energization are selected to cause intentional misregistration at a high spatial frequency which is unnoticeable to the naked eye of a viewer of the image, thereby masking any unintentional mechanical misalignment of the print heads while maintaining imperceptible the intentional misregistration of the solution to the problem.
