Abstract (en)

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 (10) comprising a plurality of light emitting cells, - encoding means (30,40) 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 (50,11,12,13) for selecting row by row the cells of said active matrix (10)and converting, sub-frame by sub-frame, the sub-frame data delivered by said encoding means 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.
