Abstract: A method for regulating the biasing voltage of column control circuits of an array screen formed of LEDs distributed in lines and columns, the column control circuits being adapted to turning on at least one LED of a line. The method consists of increasing the biasing voltage when the current flowing through at least one activated LED is smaller than a determined luminance current and of decreasing the biasing voltage when the current flowing through each activated LED is equal to the determined luminance current.

Abstract: The invention relates to a process and device for scanning cells of a matrix-controlled display for the displaying of grey levels of a video signal, the scan being split up into sub-scans relating to each bit of column control words, characterized in that, when the coding of image does not activate the high-order bit, the processing sub-scan relating to this bit is allocated to the displaying of an additional item which corresponds to a bit of lower weight than the smallest weight of the column control word used when the condition is not fulfilled. The applications of the invention relate to matrix-controlled display devices using the principle of temporal modulation for the generation of halftones, especially plasma panels of the a.c. type with memory or d.c. type with memory.

Abstract: A bottom open display case for jacketed cassettes wherein the jacket is retained in the display case which itself is of transparent plastics material. A base is attached to the bottom end of the display case and is slidable laterally from a closed position to an open position where an opening in the base aligns itself with the cassette in the display case allowing the cassette to be removed from the display case. A flexible tab on an end wall of the display case acts as a spring to return the base to its initial closed position where it is out of alignment with the cassette in the display case.

Abstract: Disclosed is a method for the addressing of each column of a matrix type LCD panel consisting in the production of a pulse to control a driver transistor of said column, said pulse having a duration determined by the value of the video signal sample at input, said pulse acting on the conduction state of said transistor to connect said column to a supply terminal where a voltage gradient develops. According to the method two pulse durations, the sum of which is predetermined, are alternated and, in order that a given value of a video signal sample may produce the same optical effect from one period to the next one, differentiated excitation voltages are applied to at least one of the electrodes sandwiching the liquid crystal layer, namely said column and its counter-electrode. Application notably to active matrix LCD panels.

Abstract: A method for the control of a display screen whose pixels are cells producing light is used to minimize certain image defects known as excess brightness defects caused by major variations in the number of cells activated. For this purpose, the invention operates on the sub-division of the activation times of the cells during a given cycle time to reduce a time during which cells, selected as a function of their luminance level, are the only ones to be activated. The disclosed method can be applied especially to the control of alternating type plasma panels.
