LIQUID CRYSTAL COLOR DISPLAY PANEL WITH ACTIVE ARRAY Russian patent published in 1994 - IPC

Abstract RU 2018892 C1

FIELD: production of liquid crystal panels. SUBSTANCE: additional address bus is introduced into the panel. Lines of image elements of the array form groups of two lines, which are repeated periodically. In the first lines of any group drains of all four switching transistor of each image element are connected to data bus, disposed between image electrodes of the image element. Gates of the second and the fourth switching transistors are connected to address bus, disposed between two subsequent lines of image elements. Drains of all four switching transistors of image elements of the second line from the group are connected to one of two data buses, disposed between the image element and preceding image element, or between the image element and subsequent one in the same line. Gates of the second and the fourth switching transistors are connected to address bus, disposed between two subsequent lines of image elements. Gates of the second and the fourth switching transistors of image elements of the last line of the array are connected to additional address bus. EFFECT: improved efficiency. 4 dwg
