  • Method for displaying additional colors
    Publication number: 20050195180
    Abstract: A method of displaying additional colors is provided to enable a flat panel display (FPD) to display a required color which is originally unavailable due to hardware limitations of the FPD by using two available colors of the FPD, such as, a first and a second color. At least a pixel of the FPD is initiated to display the first color and a response time of the FPD is allowed to substantially elapse. Next, the pixel is initiated to display the second color, and at least a time equivalent to a display-achieving period is allowed to elapse, in which the period is based on, numerically, the first and second colors, the required color, and the response time. The pixel is then initiated to change its color alternately in a sufficiently small scale, thus achieving displaying the required color substantially.

  • Memory use and management method and system for a multi-pass printer
    Publication number: 20050141031
    Abstract: A memory use and management method and system for a multi-pass printer. The system has a band buffer, a band buffer manager and a print engine. The band buffer receives and masks an input data, and stores masked data resulting from masking the input data. The band buffer manager is connected to the band buffer in order to start to print the masked data as the band buffer stores an amount of one complete print pass for a printhead of the printer. The print engine has the printhead and is connected to the band buffer such that the print engine receives the masked data from the band buffer and prints it by the printhead. Data amount stored in the band buffer can be represented by an equation, [(1+2+3+ . . . +j+j)/(i*j)]*S, where j indicates partitioned number of one complete print, and S indicates data amount required by one complete print.
