Advantages

16. 15/30
OLED TV Contrast
OLED: Pixel Unit, Pure Black Level  무한대 C/R
 Bartleson-Breneman Effect: Contrast & Perceived Brightness
- Display with higher contrast looks brighter

17. 16/30
OLED TV Color
OLED: Wide color gamut, Perfect color accuracy
 Helmholtz-Kohlrausch Effect: Color Gamut & Perceived Brightness
- Display with wider color gamut looks brighter

OLED TV Viewing Angle
Wide viewing angle, color-shift free
LCD 특성
• 계조 구분: 光學的 異方性 이용
- 정면과 측면의 근본적 화질 차이
• 광시야각 모드 액정 (IPS, PVA)
- 시야각과 계조 반전 해결
 측면 시인성 저하 문제
OLED 특성
• 자발광 디스플레이
 시야각 특성 우수
