Abstract: A method and apparatus for displaying a video picture on a matrix array of light emitting elements form of m rows and n columns of such elements. The video signal, which is comprised of periodic vertical intervals, each containing successive line intervals of video information, is sampled at a rate of n samples during each line interval. The resultant, n sampled picture elements for each sampled line interval in each vertical interval are stored. During a vertical interval, a given light emitting element, such as the i-th element in the j-th row, corresponding to a sampled picture element in a respective line interval, is energized for a duration greater than a line interval and less than a vertical interval as a function of the brightness of the sampled picture element when that sampled picture element is between and black and peak white levels. In a practical embodiment, a storage circuit stores the n sampled picture elements in each line in an mxn matrix array of storage elements. These stored, sampled picture elements are recirculated on a row-by-row basis periodically, all of the sampled picture elements being fully recirculated in a period which is less than the vertical interval. Each of the m rows of light emitting elements are conditioned sequentially are repetitively, in synchronism with the recirculation of the sampled picture elements in the storage circuit. A reference voltage generator generates a reference voltage of staircase waveform during each vertical interval, the step interval of the staircase waveform being equal to the aforementioned period. During each such period, the brightness of each picture element which is shifted into the first row of the storage circuit is compared to the reference voltage, and the columns of light emitting elements are selectively enabled for a duration that is a function of the brightness level of corresponding sampled picture elements. A light emitting element is energized if it is disposed in a row which is conditioned and in a column which is enabled.

Abstract: PURPOSE: To make the device simple in structure, small in size and high in the brightness of a displayed video and to remarkably improve availability by irradiating a mirror polarization type light modulator with light at different angles of incidence and angles of reflection in the same direction in accordance with two or more tilt angles. CONSTITUTION: Projected lights LR and LB in two colors are allowed to irradiate a first mirror polarization type light modulator 41RB for modulation in time-division according to video data in two colors with different angles of incidence and angles of reflection in the same direction. Also, a projected light LG in colors except two colors is irradiated on a second mirror polarization type light modulator 41G for modulation according to video data in colors except two colors. Then, effective reflected lights corresponding to the video data reflected on the first and second mirror polarization type light modulators 41RB and 41G are synthesized by synthesizing means 43G and 43RB. Thus, the device can be made simple in structure, small in size and high in the brightness of the display video.

Abstract: PURPOSE:To improve the efficiency of graphic input work by using an electronic input device usable similarly as the template of a drawing tool. CONSTITUTION:A second display 5 can be used similarly as the template of the drawing tool. In other words, the second display 5 is placed at a required position by moving on a first display 2 by moving the second display 5 on a tablet 3. Then, the position of the second display 5 on the first display 2 can be detected by position detecting means 81-83. And by selecting a required graphic or character from a various kinds of graphics and characters being displayed on the second display 5, a selected graphic or character is displayed at the position detected by the position detecting means 81-83 on the first display 2.

Abstract: PURPOSE: To provide an indication device which is used for a large space light modulator and not restricted by wiring and a sensor. CONSTITUTION: A display system provided with a pointer which is not restricted by wiring and the sensor is provided. The space light modulator 14 for projecting an image on a screen 20 is used for display. While all cells in the modulator 14 are in the same state, a cursor projected on a screen by the pointer is image- formed again in a detector 26 from the screen. The detector 26 converts the image of the cursor into a signal transmitted to a central processing unit. The central processing unit makes a system face a task instructed by the cursor.
