Ferroelektrisches Flüssigkristalldisplay mit breitem Arbeitstemperaturbereich

摘要

The invention relates to a ferroelectric liquid-crystal display containing a ferroelectric liquid-crystal mixture, characterized in that the display is controlled with voltage pulses >/=0.9 ms. The display provided for by the invention is especially suited for applications in which the length of switching time is not critical. Such displays can be switched with the same voltage in a very wide range of temperatures, thus making it unnecessary for the voltage to be adjusted in line with the temperature. Potential applications include displays in chip cards, electronic pricing or display signs (shelf labels), PDAs (personal digital assistants) and pagers.
