Abstract: During a first half of the frame time, the successive odd lines of the first part (10) of the screen are selected simultaneously with the successive even lines of the second part (12) of the screen. During a second half of the frame time, the successive even lines of the first part (10) of the screen are selected simultaneously with the successive odd lines of the second part (12). The information to be displayed during selection is contained in registers (72, 78). The information to be displayed during the following selection are recorded in buffer registers (70, 76) and originate from a source (22) for the odd lines and from a memory (62) for the even lines. This memory (62) records the data to be displayed on the even lines in step with their delivery by the source (22).

Abstract: The red-, green- and blue- coloured pixel elements forming a coloured pixel are disposed in the form of a triangle. A pixel element consists of a thin-film transistor connected to one electrode of a capacitor, this electrode facing a second coloured electrode. The electrodes connected to a transistor are arranged in rows, the other electrodes in columns. Each column of electrodes corresponds in succession to a red, green and blue colour. Three electrodes connected to three thin-film transistors and forming a coloured pixel are connected to the same addressing row conductor. … …

Abstract: Method of displaying grey scale on a matrix display screen, such as for example a chiral smectic-phase ferroelectric liquid crystal screen comprising a cell containing the crystal and provided on its walls with two matrix systems of i row conductors and j column conductors at right angles, various pixels of the image being defined by the overlying crossings of these conductors, characterised in that each pixel is produced with the aid of p independent sub-pixels each having its own transmission coefficient, and each of which is able to display several different fundamental grey states, including black and white, and one of the previous grey states is displayed on each of the p sub- pixels whilst taking account, for each of them, of its own transmission, so as to obtain for each pixel, by visual addition of the contributions from each sub-pixel, the displaying of the appropriate shade of grey, closest to the analog value indicated by the video write signal.

Abstract: Les points d'image élémentaires de couleur rouge, verte, bleue formant un point-d'image couleur sont disposés en triangle. Un point d'image élémentaire est constitué d'un transistor en couches minces relié à une électrode d'un condensateur, cette électrode faisant face à une seconde électrode colorée. Les électrodes reliées à un transistor sont rangées en lignes, les autres en colonnes. Chaque colonne d'électrodes correspond à une couleur successivement rouge, verte, bleue. Trois électrodes reliées à trois transistors en couches minces et formant un point d'image couleur sont reliées à un même conducteur ligne d'adressage. Application à l'affichage d'images fixes ou animées.

Abstract: The source comprises columns (4) emitting electrons and rows (6) of which the potential develops up to a positive value VI. The screen also comprises at least one supplementary column (24) common to all the rows, means (28) for carrying this supplementary column to a negative potential such that, irrespective of the potential of the rows which it crosses over, electrons may be emitted in the crossover zones, at least one supplementary anode (26) facing the supplementary column and means (30) for carrying this supplementary anode to a positive potential lower than VI. Each row is controlled by a single output transistor (32) which, when the latter is on, carries the line to VI and which, when off, disconnects the line from the voltage source VI. Application to microtip screens.
