  • Matrix display device with reduced loss of resolution
    Patent number: 6768477
    Abstract: Matrix display device (1) wherein multiple line addressing is performed by a unit (LD). As a consequence of the multiple line addressing, there is a difference between the luminance values actually displayed (C) and the original luminance values (D). The visible effects of said difference or error (E) are minimized by subtracting said difference or part thereof from the original luminance values, either from neighbouring pixels to be displayed and/or from the same pixels of the subsequent frame. Said neighbouring pixels are preferably the pixels directly below or to the right of the ones considered. The latter is obtained by applying a sample delay to the error (E).
    Type: Grant
