120Hz, 240Hz and 240Hz Effect LCD Anti-blur Technologies Compared

LG LH55 LCD with combined motion interpolation and scanning backlight

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

LCD with Backlight Scanning

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.

Best Plasma HDTV

Panasonic VIERA V10 Plasma HDTV

Panasonic has an extensive range of plasma HDTV models with varying features. Our pick for Best Plasma HDTV is not the premium TC-P54Z1 which includes Wireless HD connectivity but the larger 65 inch Panasonic TC-P65V10 which is also available in 3 smaller sizes down to 50 inches. The TC-PV10 series has Panasonic’s new NeoPDP technology which has delivered brighter displays, doubled luminance efficiency, deeper blacks, improved contrast ratios and reduced power consumptions (1/3 of 2007 models for the same brightness). With plasma HDTVs genuinely wide viewing angles ensure all viewers will enjoy the same image quality.

Prysm’s Laser Phosphor Displays (LPD) | Large Format

LDP Display Logo

Prysm Inc’s new class of display Laser Phosphor Display (LPD) has gained attention primarily for energy consumption up to an enormous 75% less than other display technologies. Low power consumption is particularly significant for this display technology as it is currently aimed at larger format display applications. Having the wide viewing angle of plasma (another emissive display) combined with very low power consumption (definitely not a characteristic of plasma displays) makes LPD perfect for large scale public signage and advertising.

LG LH85 1080p LCD HDTV with Wireless Connectivity Review

LG LH85 LCD 1080P HDTV

LG’s LH85 1080p LCD HDTV series is one of its premium LCD series which utilise a conventional CCFL backlight. The LH85 models differs little from the LH50 series or LH55 with those models having NetCast and 240Hz TruMotion Drive as differentiators instead of Wireless Connectivity. LH85 models have 120Hz TruMotion Drive rather than the 240Hz of the LH55. The LH85 series delivers good image quality for a more affordable price than a higher performance Plasma or LED LCD HDTV. Underlying the good picture performance is a high dynamic contrast ratio of 80,000:1.
