<p>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. According to the invention, a two-stage memory element having a volatile and a non-volatile memory (5 and 6) is used that stores the enormous volumes of data resulting from this context. The inventive solution also works with at least two temporally decoupled cycles for determining the pixel wear values and for determining the pixel correction values.</p> |
