  • Optical display system and liquid crystal cell having electrode details for efficient manufacturing
    Patent number: 5530574
    Abstract: A liquid crystal cell (60) for an optical display system has a first transparent electrode structure (62) including plural separate display electrodes (72A-72E) spaced apart from and generally parallel to a second electrode structure (64) including a common electrode (106) opposing the display electrodes across a thin layer (76) of liquid crystal material captured between the two electrode structures. Each display electrode has left (92A-92E) and right (94A-94E) ends having respective electrical contact areas (96A-96E, 98A-98E). The left and right ends of each display electrode are electrically driven with a drive signal (V.sub.DRIVE (A-E)). The common electrode has top (116) and bottom (118) ends located adjacent respective top (108) and bottom (110) side margins of the second electrode structure and having top center (120) and bottom center (122) locations with respective top and bottom electrical contact areas (124, 126).
