3투사렌즈방식 LCD 프로젝션 TV의 엔진 냉각에 관한 연구
A study on the cooling method for LCD projection TV with 3 projection lens
초록
We have developed new rear LCD Projection TV engine with 3 projection lens. It has high brightness and contrast ratio, however poor cooling conditions. If optical components close to light source, optical components are damaged on high temperature, especially the blue among RGB colors is weakest by heat In this study, a new enhanced cooling method of LCD projection TV with 3 lens is shown: the best suited design of duct and relations between LCD panel and polarizer lifetime with changed area of duct.
