LED backlighting units come in two flavours typically for desktop monitors, those being White-LED and RGB LED. With White-LED (W-LED) The LED's are placed in a line along the edge of the matrix, and the uniform brightness of the screen is ensured by a special design of the diffuser. The colour gamut is still limited to around 68% NTSC but are cheaper to manufacturer and so are being utilised in more and more screens, even in the more budget range. They do have their environmental benefits as they can be recylced, and they have a thinner profile making them popular in super-slim range models and notebook PC's.
白光LED 放在屏幕边缘的 色域只有68% 但是厂家成本更低 还有环保的好处 对用家的唯一好处是可以更薄一点
Enhanced / Wide CCFL Backlighting (W-CCFL)
More recent displays have started to utilise a newer generation of CCF lamps, offering a widened gamut and typically a coverage of the NTSC colour space of 92 - 97%
普通的CCFL色域一般为72% 改进的CCFL可以有92%~97%
RGB LED色域最高可以达到114% |
