By Greg Tarr -- TWICE, 10/28/2009
Yokohama, Japan. - Samsung Electronics unveiled here Wednesday what it called the world's thinnest 40-inch FullHD 120Hz LCD panel, measuring 3.9mm thick and targeting TV applications at FPD International 2009, according to a Nikkei report.
It has an edge-lit LED backlight. To achieve the thinness, Samsung Electronics made improvements to the optical elements so that LED light efficiently and evenly comes to the liquid crystal cells. However, the company declined to comment on technical details such as the number and alignment of LEDs and the optical elements.
Panel brightness was listed as 400cd/m2, and the contrast ratio is 5,000:1.
The company also showed two similarly designed ultra-slim LCD panels intended for PC monitors and notebook PC applications. The panel for monitors measures 24 inches and 3.5mm thick, with a 1,920-by-1,200 pixel resolution and 250cd/m2 brightness.
The notebook panel measured 12.1 inches, 1.64mm thick and had a pixel count and brightness level of 1,200-by-800 pixels and 200cd/m2, respectively.
