Abstract
The method for the representation of video and audio signals on a low-resolution display panel, which includes the steps of: scaling the video or audio frame to fit the display panel, quantization of the video or audio signals to predetermined level values, temporal representation of video data by using the pulse density modulation, sending the signal pulses to the display panel. In further aspect the step of temporal representation contains the anti-flickering signal manipulation technique incorporating maximization of separation of the pulses during the pulse density modulation.
