摘要： In a method and device for a sub-field driving a display device, in which sub-fields are weighted and duplicated for achieving a plurality of gray levels by way of a plurality of sub-fields, the sub-fields are weighted as a ternary distribution of sub-field weights.

摘要： Apparatus for identifying the four coordinates of a window on a visual display monitor, include a device for obtaining digital data corresponding to pixels of an image to be displayed on the monitor, a memory arranged to receive the digital data, a comparator arranged to compare the values of data for horizontally and vertically adjacent pixels, a generator for generating a gradient value indicative of the difference in luminance of adjacent pixels—in the horizontal and in the vertical directions, a memory for storing the gradient values, a detector for detecting a unique configuration in the gradient values to identify the three coordinates of one edge of the window, and a device for checking in the direction perpendicular to the identified edge for a corresponding unique configuration, to determine the fourth coordinate of the window.

摘要： The invention relates to an AC plasma display panel (12) of the surface discharge type, and more specifically to the structure of the address electrodes (5) of said panel, and to a method of driving said panel. According to the invention, only one address electrode (5) is used for one out of every two columns. Scan (8) and common (7) electrodes may comprise transparent parts (11). These parts (11) may extend over one out every two cells, in a checkerboard fashion. In a preferred embodiment as shown in FIG. 7, the columns may have alternating wide (15) and narrow (16) cells (2). In the driving method according to the invention, all rows are addressed during an addressing phase, and subsequently all rows are simultaneously sustained during a sustain phase.
