    Abstract: PURPOSE:To realize a projection type picture display device where the distortion of an image and the distortion of input coordinate are almost eliminated. CONSTITUTION:This device is provided with a correction data ROM 45 which holds data for correcting the skewness of a position detected by a transparent tablet plate 40, a correction data ROM 50 which holds data for correcting the distortion of an optical image caused by an optical system, and a coordinate transformation means(system controller 20) which holds a coordinate transformation expression for correcting the distortion which is not caused by the transparent tablet plate and the optical system, and coordinate transformation processing and the correction by the correction data read out of the ROMs 45 and 50 are applied to a scanning position control signal for executing picture display by a laser beam.

    Abstract: PURPOSE:To let bar-luminous length change following impressed voltage faithfully by arranging charging electrodes serratedly and intermittently. CONSTITUTION:A couple of charging electrodes 11a, 11b, is coated on the internal surfaces of base plates 12a, 12b, on which are respectively coated insulated layers 13, on which are coated protective films 14. Electrodes 11a, 11b along base plates 12a, 12b are arranged to increase or decrease gradually in their clearance as a position I on the monotonous increasing range moves to another. Regarding the electrodes, 11a, 11b, both or one of them are or is electrically connected with each other so that the equivalent quantity between both electrodes 11a, 11b, can change from the position I to another step by step. Moreover, from the position I to another are arranged plural serrated electrode parts 11a1-11an and 11b1- 11bn which have desired widths.

    Abstract: A video display system employing a flat display panel of X-Y matrix type, signal sampling means, "write in" and "read out" memory circuits serially connected between the signal sampling means and the display panel, and a novel signal control means connected to the "write in" and "read out" memory circuits wherein the number of lines or leads for distributing signals from the "read out" memory circuits to the display panel and the number of memory devices used in the "read out" memory circuits are reduced substantially.
