24. The truth of the bright It is really good if it is just bright ? PDP: To be bright changes according to the screen area → Natural comfortable at the eye intensity. LCD: Always high bright without the relation of the screen area → The eye is tired if it sees continuously. Bright characteristic ( Source: 大阪교육대학 인간행동학과 高橋 誠 교수 연구, 2005) PDP : Characteristic is similar with CRT LCD : Don't do the bright adjustment according to the screen area Need natural intensity expression to reduce the fatigue of the eye.
