  • Patent number: 7612787
    Abstract: The invention concerns a display (1) afflicted with wear, and to a method for operating a display (1) of this type. In conjunction with the problems associated with the burning in of non-moving images or image elements in wear-afflicted displays, particularly plasma displays, and with the problems associated with the wear-characteristics, which differ in the individual primary colors red, green and blue, of the phosphorous cells of a display (1) of this type whereby resulting in a shift in the color temperature of the image reproduction, the invention provides that the latest pixel wear values (R*, G*, B*) are written into a memory element (3), whereby pixel correction values are determined by means of a logic element (2), which is assigned to this memory element (3), and corrected pixel values R?, G?, B? are generated from these pixel correction values and are applied to the display (1) for homogenizing the individual pixel wear values.

  • Publication number: 20080180354
    Abstract: The disclosure relates to a method for operating a display device (100) with a plurality of pixels (p)—preferably arranged in matrix form—beset by wear, in which each pixel (p) has applied to it a drive signal (S) assigned to it, in which a wear value (V) as a measure of the individual wear of the respective pixel (p) is determined for each pixel (p) depending on the drive signal (S), and in which a correction value (K) for correcting the drive signal (S) is determined depending on the wear value (V), characterized in that the process of determining the wear value (V) has certain steps as set forth in the disclosure.

  • Publication number: 20080150971
    Abstract: A method for operating a display device having a plurality of wear-afflicted picture elements is provided. Each picture element is acted upon by a control signal assigned to it. A wear value for at least one picture element is determined, the wear value being a measure of the wear of the picture element. The wear value is determined as a function of at least one of the following: the temperature of the picture element and the temperature of at least one adjacent picture element.
