Jayawardan Janardhanan has filed for patents to protect the following inventions. This listing includes patent applications that are pending as well as patents that have already been granted by the United States Patent and Trademark Office (USPTO).

  • Supporting variable line length in digital display timing controllers using data enable signal
    Patent number: 7006115
    Abstract: A digital display unit which receives horizontal lines of unequal length in a V-active region and computes an average length of the lines. The average is used to generate horizontal line demarkers in the V-blank (vertical blank) region. The demarkers specify the transition from one line to the other. Such a feature is useful in spread spectrum clocking (SSC) based display signals in which HSYNC signals may also not be available to determine the transitions from one line to another in the V-blank region.
    Type: Grant

    Date of Patent: February 28, 2006
    Assignee: Texas Instruments Incorporated

  • Method to upscale single-pixel wide text without loss of image sharpness
    Patent number: 6891968
    Abstract: A method to upscale single pixel wide text associated with flat panel display applications has a reduced cross-sectional area in two dimensions as compared to scalers that are either rule based or based on pattern matching. The method to upscale single-pixel wide text retains the sharpness of the single pixel text associated with flat panel display applications while requiring substantially smaller memory buffer requirements.
