Abstract: A video system that performs TV signal decoding, deinterlacing, and de-motion-blurring for progressive scan flat panel display is introduced. The system embeds a frame buffer and a scaler for conducting format and resolution conversions for display panels of different sizes. The output of the scaler is sent to a de-motion-blur processor for reducing the blurriness due to the motion of image objects and the slow response time of flat panel display devices. The de-motion-blur processor gets the motion and noise indication signal from scaler or the pre-frame-buffer video processor. Based on the motion and noise information and the information of temporal difference, the de-motion-blur processor performs over driving for the display panel interface and improves the rising and falling response time of the flat panel display. The decoding, deinterlacing, and de-motion-blur processing share the same frame buffer controller so the entire system can be optimized in cost and performance.

Abstract: The invention is related to a new kind of plasma display panel control. A known principle for PDP control is based on a combination of sub-field addressing and priming. Within the priming period all the plasma cells of the panel are pre-excited by a strong voltage pulse. This treatment of the cells produces a slight background luminance which is a drawback for picture quality aspects because the achievable contrast is reduced. According to the invention it is proposed to use self-priming sub-fields and refreshing sub-fields instead of this hard priming period. With these concepts it is assured that the cells which ought to be black remain black. Self-priming sub-fields reduce or eliminate the need for priming, thus making dark areas darker, while refreshing sub-fields, can be addressed faster. In practice, the number of refreshing sub-fields in a frame period is higher than the number of the self-priming sub-fields. Therefore, the total addressing time can be reduced with this new technique.

Abstract: A flat-panel direct view display positions an array of electrostatically-actuated cantilevered micromirrors in front of a contrasting background and opposite a flat-panel electron beam source. Depending upon the display configuration, the electron beam source addresses either the array of micromirrors or a reference surface a row at a time while the other is held at a reference potential. The electron beams modulate the potential difference between each micromirror and the reference surface thereby adjusting the magnitude of the attractive electrostatic force between the two. This in turn modulates the deflection of the micromirrors between their quiescent and fully actuated states to selectively cover and uncover the background thereby producing a grey scale direct-view image.
