LIQUID-CRYSTAL SCREEN WITH ACTIVE MATRIX Russian patent published in 1998 - IPC

FIELD: liquid-crystal screens. SUBSTANCE: proposed screen includes first insulating substrate, assemblage of address wires formed on first insulating substrate one in parallel to another, assemblage of data wires formed on first insulating substrate perpendicular to address wires, assemblage of image elements formed on first insulating substrate in the form of matrix of lines and columns arranged between address and data wires correspondingly. Each image element has at least tow image electrodes insulated one from another and two switching over transistors as minimum. In compliance with invention each image element includes two additional capacitors and . First additional capacitor is connected to second data wire and to first image electrode and second additional capacitor is connected to first data wire and to second image electrode. EFFECT: high quality of image transmission, enhanced operational reliability of screen. 3 cl, 12 dwg
