NuVision 42LCM1 42 inch 1080p LCD Display Review

Nuvision 42LCM1 42 inch 1080p LCD Display

NuVision is a relatively new arrival on the wide screen high definition manufacturing scene. It has recently released two 16:9, 1080p (1920 x 1080 pixel resolution) high definition LCD TVs to add to its existing LCD range. An example of NuVision’s emphasis on pushing technological boundaries is its newly released, and reviewed, 1080p LED DLP rear projection TV, the 52 inch 52LEDLP, which utilizes Luminus’s PhlatLight LED chipset to replace the conventional color wheel and lamp assembly used by DLP systems.

In regard to the 42 inch 42LCM1 1080p LCD TV, NuVision have produced an LCD with impressive brightness, contrast and response time. So how do they compare with similar size LCD televisions from more well known brands?

  • At 600 cd/m2 the 42LCM1’s impressive brightness is higher than Sharps AUOS LC-46D62U (450 cd/m2) and Samsung’s LE45F71B (450 cd/m2).
  • Its contrast ratio of 1200:1 is less than Sharps AUOS LC-46D62U (2000:1 and 10,000:1 dynamic), Sony’s Bravia KDL-46XBR3 (1300:1 and 7,000:1 dynamic) and Samsung’s LE45F71B (6,000:1 dynamic)
  • While its response time 8ms is excellent, it is slower than the blistering 4ms of Shap’s AUOS LC-46D62U and equals the 8ms of the Samsung LE45F71B.
  • The viewing angle of 176 degrees is satisfactory and only slightly exceeded by Sony’s and Samsung’s 178 degree range.

    NuVision’s 52LEDLP 52 Inch LED DLP Rear Projection TV – Review

    On November 10, Luminus Devices announced that “NuVision, a premium HDTV manufacturer that targets the CEDIA custom installation channel and high-end A/V specialty retailers, has begun shipping its 1080p Deep Black LED DLP television (model # 52LEDLP) with PhlatLight technology.” In the NuVision 52LEDLP, Luminus’s PhlatLight LED chipset, replaces the conventional color wheel and lamp assembly used by DLP systems.

    NuVision 52LEDLP 52 inch DLP RPTV

    The NuVision Deep Black LED DLP television, 52LEDLP, is the second PhlatLight LED utilizing television to be released this year. Samsung Electronics launched its HL-S5679W 56-inch LED Engine Widescreen DLP RPTVs several months ago. The HL-S5679W won the CNET Best of 2006 Award in the TV category.

    PhlatLight is a solid state light source - is a tri-color (red, green, blue) LED built as a single, large area monolithic chip. Luminus’s chip is (quoting Luminus) “designed expressly to meet the requirements of microdisplay illumination” such as the Texas Instruments 1080p microdisplay chip such as in the case of the NuVision 52LEDLP.

    NuVision’s specifications for the 52LEDLP state that an xHD4 DMD is used – a term used by numerous manufacturers to refer to the DLP microdisplay chip referred to by Texas Instruments as the 1080p. This chip is advertised as delivering native 1080p (1920 x 1080). Each TI 1080p microdisplay chip has a surface array of some 2.2 million microscopic mirrors (one per pixel) which swivel to reflect the light source as necessary to create the desired images for video playback.
