摘要：The present invention relates to a grayscale rendition method in an activematrix OLED (Organic Light Emitting Display) where each cell of the display is controlledvia an association of several Thin-Film Transistors (TFTs). In order to improve the
grayscale rendition in an AM-OLED when displaying low grayscale levels and/or whendisplaying moving pictures, it is proposed to split each frame into a plurality of subframeswherein the amplitude of the data signal applied to a cell of the AM-OLED can beadapted to conform to the visual response of a CRT display. According to the invention,the video frame used for displaying an image is divided into N consecutive subframes,with N≧2, and the data signal applied to the cell comprises N independent elementarydata signals, each of said elementary data signals being applied to the cell during asubframe. The grayscale level displayed by the cell during the video frame is dependingon the amplitude of the elementary data signals and the duration of the subframes.
