Abstract
A cholesteric display includes a display controller and a database. The database includes a control program for programming the operation of the display controller, a display field for storing information to be displayed at the cholesteric display, and a temperature range field for storing the temperature range of the environment of the cholesteric display. An input device is provided for loading control program, display information, and temperature or temperature range data to the database.
Claims11
A method for controlling a cholesteric display, comprising:
- storing display image data and temperature data in a database;
- providing said image data and temperature data to a display controller;
- and
- operating said display controller to convert said image data and temperature data to a voltage-time sequence for driving said cholesteric display.
A system for controlling a cholesteric display, comprising:
- a display controller;
- a database, said database including a control program for programming the operation of said display controller, a display field for storing display information to be displayed at said cholesteric display, and a temperature range field for storing the temperature range, of the environment of said cholesteric display;
- and
- an input device for loading control program, display information, and temperature range data to said database.
A program storage device readable by a machine, tangibly embodying a program of instructions executable by a machine to perform operations for controlling a cholesteric display, said operations comprising:
- storing display image data and temperature data in a database;
- providing said image data and temperature data to a display controller;
- and
- operating said display controller to convert said image data and temperature data to a voltage-time sequence for driving said cholesteric display.
