Abstract:

RECENTLY DEVELOPED COMMERCIAL LAPTOP LCD TERMINALS, USING A POWDER, ELECTRO-LUMINESCENT BACKLIGHT WITH A SUPER-TWIST, LCD DISPLAY SURFACE, EXHIBIT MUCH-IMPROVED VIEWING CONTRAST AND BATTERY LIFE. THE BACKLIGHT SYSTEM STILL CONSUMES 90 PERCENT OF THE POWER. IN THE CASE OF COLOR LCD DISPLAYS, THE BACKLIGHT POWER CONSUMPTION IS EVEN WORSE: AS MUCH AS 96PERCENT OF THE BATTERY POWER IS WASTED ON THE INEFFICIENCY OF THE BACKLIGHT SYSTEM. A HIGH-EFFICIENCY BACKLIGHT SYSTEM, BASED ON THE USE OF THIN-FILM ELECTROLUMINESCENCE (TFEL) COLOR STRIPES AS THE LIGHT SOURCE, COUPLED WITH CONCENTRATING OPTICS, COULD HAVE A SIGNIFICANT IMPACT ON BATTERY LIFE FOR A PORTABLE COMPUTER. IN PARTICULAR, THE NEW COLOR BACKLIGHT DESIGN COULD RESULT IN A 10-FOLD INCREASE IN EFFICIENCY OVER THE CURRENT DESIGN. OTHER FEATURES INCLUDE MINIMUM BACKLIGHT THICKNESS AND EXCELLENT TEMPERATURE STABILITY. PHASE I WILL ESTABLISH THE FEASIBILITY AND COMPATIBILITY OF THE VARIOUS COMPONENTS REQUIRED FOR THIS ADVANCE.
