摘要： The invention relates to planar display screens and more particularly to smectic liquid crystal screens.One of the problems of high definition display screens (approximately 100 to 1000 lines and columns) is caused by the devices for controlling the heating current on the lines. The complexity of the installation and costs limit the increase in the definition. The invention arranges the N lines of a screen into .sqroot.N groups of lines supplied at each of their ends by .sqroot.N control devices functioning sequentially, i.e. 2.sqroot.N devices in all. Moreover, each line has a diode placed between the heating resistor and the common point of the circuit.Application to the display of images transmitted in the form of a video signal for television and display peripheral equipment in teletransmission.

摘要： A display device having a memory making it possible to display information supplied by electric signals and to maintain this display when the signals have disappeared. In a smectic liquid crystal display cell the two plates enclosing the liquid crystal layer can be moved apart by a piezoelectric wedge so as to make the crystal diffusive throughout. Parts of this crystal are then made transparent by applying thereto a reorientation electric field by means of a set of electrodes. The device is intended for use more particularly in telephone exchanges having a device for the display of digital data transmitted on a telephone line.

摘要： In a liquid-crystal display device, a smectic liquid-crystal layer and a layer of photoconductive material are placed between two transparent plates. A voltage is applied to the photoconductor by means of electrodes while scanning the photoconductor with a writing light beam. At locations in which the resistance of the photoconductor is reduced under the action of the light beam, the heat generated causes transition of the liquid crystal to the isotropic state. The light-scattering action produced by subsequent cooling of the liquid crystal has the effect of writing the image to be displayed.

摘要： The invention provides an optical display device, utilizing a thermo-optical effect to inscribe a transmitted image in a layer of a material exhibiting a smectic state. Recording of the image with a full range of half tones without modulation of the recording beam and quick erasure of the recorded image without reheating of the film can be obtained by directly applying, simultaneously to the whole of the film either the video signal or an erasure voltage of suitable values. By associating this display device to a projection device utilizing a very bright source, the image thus recorded can be projected onto a large screen or a photosensitive substrate. The invention also describes a color images teleprojection and telereproduction device, in which three distinct chrominance images are recorded in a smectic layer as above described and simultaneously illuminated with white light; the three beams thus obtained are filtered for respectively selecting in each of them the spectral band corresponding to the chrominance of the image and superimposed in a single beam by a reflecting system. An objective lens supplied with a diaphragm in its image focal plane receives this single beam and projects the reconstituted colour image onto a screen or a photo-sensitive layer.

摘要： The invention provides a liquid crystal imaging system which employs a transitory thermo-optic effect to permit notably the reproduction of T.V. images. This transitory effect is characterized by the fleeting appearance of scattering cybotactic zones in the transparent liquid phase of a mesomorphic material, at the very beginning of the transition to a nematic transparent ordered phase. The duration of the scattering period can be considerably shortened by subjecting the mesomorphic material layer to the action of an alternating electrical field.

摘要： A telecopying process and a transmitter-receiver telecopier employing this process. A cell having a smectic liquid crystal is used for recording by thermo-optically forming an intermediate image of a linear element (column portion or a whole line) of the transmitted document, which image is thereafter projected onto a photosensitive surface. The same optical system permits, when transmitting, the reading of this linear element by a mosaic of detectors and, when receiving, the projection onto the photosensitive surface of the intermediate image recorded in the cell.
