LED LCDBest LED LCD HDTVs Full array LED backlighting combined with local dimming produces the best picture quality of any LCD HDTV. The Series 8, 55 inch UN55B8500 by Samsung has the best picture performance of any Samsung LCD to date with superbly deep black levels and a dynamic contrast ratio of 7,000,000:1. LED Backlighting – the Advantages LED backlighting technology has numerous advantages over the conventional mercury-arc lamps CCFL (cold cathode fluorescent tube) including blur reduction, higher dynamic contrast ratio, wider color gamut, greater reliability and environmental friendliness. Full Array vs Edge-lit LED LCD Comparison Both edge-lit and full array LED backlighting solutions are being used by LCD manufacturers. Find out how much difference there is and what the advantages and detractions of each configuration are. LED LCD vs Plasma The shift from conventional fluorescent lamp (CCFL) backlighting of LCD HDTV to LED (light-emitting diodes) provides performance benefits that changed the comparative standing of LCD and plasma HDTV. We compare performance data for two premium model LED LCD and two premium model plasma HDTVs in conjunction with an examination of the technology differences between the two display formats. 120Hz, 240Hz and 240Hz Effect LCD Anti-blur Technologies Compared A conventional LCD HDTV displays video at 60Hz and is susceptible to having viewers perceive motion blur when there are fast moving on-objects such as during sports broadcasts or action films. We compare the 120Hz and 240Hz refresh rates offered by LCD manufacturers to reduce blur. Scanning Backlight A scanning backlight is a technique used by LCD HDTV manufacturers to reduce motion blur, which LCD HDTVs are susceptible to, when displaying fast on-screen motion. Motion blur is not a problem with plasma TVs. A scanning backlight is commonly used in conjunction with faster refresh rates from frame interpolation. Local Dimming Local Dimming improves the black levels and contrast ratios of LCD HDTVs which are historically a comparative weakness compared to plasma displays. Local dimming is achieved through the control of full array LED backlighting. LED LCD HDTV ComparisonLED backlighting of LCD HDTVs delivers some significant improvements over conventional Cold Cathode Fluorescent Lamp (CCFL) lit LCD. Local dimming is considered as a feature worth having as it delivers significant improvement to contrast ratios, black levels and picture quality through the ability to control backlighting in segments rather than overall as with conventional LCDs.
