  • 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.

    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.
