Abstract

Current flat panel display technologies, LCD included, present various problems such as increased weight, low process yields, low brightness, reduced viewing angle, and short life. The use of Thick Dielectric Electro-Luminescence technology (WESTAIM, February 4, 1999) in producing flat panel TVs and computer monitor displays would minimize some of the problems associated with current technology. The newly developed TDEL technology consists of a combination of thick and thin film processes that print semiconductor phosphors over a ceramic substrate. The red-green-blue semiconductor phosphors' layers emit light when an electric field is applied, reaching output levels over 10 lumens per watt (compared to 2 to 51umens per watt for current indoor TVs) . The use of Thick Film technology (20 mm layers) makes the process less susceptible to contamination by airborne particles, and also eliminates the need for the glass envelope used in conventional CRT.
