Abstract
AN ALL PLASTIC LIQUID CRYSTAL DISPLAY SYSTEM ESPECIALLY APPROPRIATE FOR NIGHT OR LOW LIGHT LEVEL ILLUMINATION USE WILL BE DEVELOPED. A KEY ELEMENT IN THE RESEARCH WILL BE THE SUBSTITUTION OF DICHRONIC LIQUID CRYSTALS FOR THE COMMONLY USED TWISTED NEMATIC (TN) LIQUID CRYSTALS. THE USE OF A DICHROIC DISPLAY PERMITS THE ELIMINATION OF THE LINEAR POLARIZERS ON BOTH THE FRONT AND REAR SURFACES OF THE CONVENTIONAL TN LCDS. THE ELIMINATION OF THE POLARIZERS NOT ONLY SIGNIFICANTLY ENHANCES THE READABILITY OF THE DISPLAY BUT IT REPRESENTS SIGNIFICANT COST SAVING IN TERMS OF MANUFACTURING EASE AND ILLUMINATION COSTS. ALSO THIS IMPROVEMENT ALLOWS THE ILLUMINATION POWER TO REDUCE TO A MINIMUM. BASED ON POLYTRONIX'S PAST AND CURRENT RESEARCH WITH ALL PLASTIC LCDS, WE ARE CONFIDENT IN BEING ABLE TO PRODUCE A DICHROIC DISPLAY WITH A THICKNESS OF 0.015 INCHES AND A WIDTH OF 0.75 INCHES CAPABLE OF BEING FORMED INTO AN AREA OF 120 DEG WITH A ONE INCH RADIUS. THIS DISPLAY WILL BE ILLUMINATED FOR NIGHT USE AND WOULD BE RELATIVELY INEXPENSIVE WITH RESPECT TO LARGE VOLUME PRODUCTION.
