Abstract:
The present invention relates to an apparatus for displaying an input picture of a sequence of input pictures during a video frame made up of N consecutive sub-frames, with N≧2, comprising an active matrix comprising a plurality of light emitting cells, encoder for encoding the video data of each pixel of the input picture to be displayed and delivering N sub-frame data, each sub-frame data being displayed during a sub-frame, a driving unit for selecting row by row the cells of said active matrix and converting, sub-frame by sub-frame, the sub-frame data delivered by said encoder into signals to be applied to the selected cells of the matrix. According to the invention, at least one of the N sub-frame data generated for a pixel is different from the video data of said pixel.
