MULTIPLEXING LIMITS OF TWISTED NEMATIC LIQUID CRYSTAL DISPLAYS AND IMPLICATIONS FOR THE FUTURE OF HIGH INFORMATION CONTENT LCDs... [Pg.79]

F. J. Kahn, H. Birecki, "Multiplexing Limits of Twisted Nematic Liquid Crystal Displays and Implications for the Future High Information Content LCDs," this volume. [Pg.142]

The first TN-LCD were simple, directly addressed segment displays as still used, e. g., for wrist watches. When attempts were made to increase the information content of the displays by time-sequential addressing in rows and lines (multiplexing) the limits of the TN cell were soon met. At higher multiplex ratios [14] contrast loss occurred, because of ever shorter addressing times. The development of the super-twisted nematic (STN) cell in 1984 [15] pushed the practicable limit to higher multiplex ratios, but it did not lead to a general solution of the problem. [Pg.218]

Multiplexed twisted nematic liquid crystal devices (TN-LCDs) are the mainstay of low power, medium information content displays. At present, the voltage threshold and the nonlinearity of the electrooptic response intrinsic to the twisted nematic structure are used to achieve multiplexing. The multiplexing level achievable using this technology is limited by the sharpness of the electrooptic response and by the variations of this response with viewing angle. ... [Pg.125]
