Super-thin plasma HDTV from Panasonic

A year ago, Panasonic showed a 150-inch plasma TV -- the world's biggest -- at the International Consumer Electronics Show in Las Vegas.
This year, instead of going evem bigger, the company is showing what it says is the world's thinnest plasma TV.
Panasonic has developed new thin-profile display panel technologies for both plasma and LCD HDTVs, with affitional advancements in picture quality and environmental performance.

The newly developed NeoPDP technology has been incorporated into two types of PDPs. The first is a super high-efficiency 42-inch PDP that achieves triple luminance efficiency, while reducing the power consumption to 1/3 of the 2007 models, yet achieving the same brightness. The second is an ultra-thin 50-inch PDP just 8.8 mm (approximately 1/3 inch) in profile at it's thinnest point. This ultra-thin panel delivers the world's highest moving picture resolution*3 of 1080 lines.

Panasonic's newly-developed NeoLCD technology is integrated into a super energy-efficient 90kWh per year 37-inch LCD panel, that achieves moving picture resolution of 1000 lines, close to that of a PDP. The company said it has the lowest energy consumption of any LCD HDTV in the world, cutting the energy requirement almost in half compared to the previous model.

Employing newly developed materials, such as discharge gas and phosphor for electron generation source has improved discharge efficiency and cell structure. The introduction of a new circuit drive method has cut the electricity loss to one third and enabled low-voltage drive. The triple luminance efficiency technology has reduced the number of components and enabled a higher integration of components. As a result, the technology has been incorporated into a 42-inch Full HD PDP.

Further advancements made to the panel structure and circuit layout have lead to an even thinner profile. While a full HD PDP has a moving picture resolution of more than 900 lines, the newly developed drive technology and materials to shorten the afterglow have attained the world’s highest moving resolution of 1080 lines, realizing precise reproduction of full HD programs of any speed without loss of detail.

The super-thin panel also allows users more setup flexibility including wall mounting and suspension from the ceiling. It also has WirelessHD-based transmission system, wide viewing angle, high contrast ratios, and newly achieved moving resolution of 1080 lines.

IPS alpha LCD panels in NeoLCD provide a high light transmission rate and low power consumption due to its panel structure. In addition, these panels feature high moving picture resolution and a wide viewing angle for displaying images that are truly natural when viewed from any angle.

Adoption of the new IPS alpha panel with improved light transmission rate and LED backlighting allows for local lighting control according to the brightness of the picture scenes. With precise control, the panel dramatically improves contrast with its tight black expression. This panel cuts power consumption in half compared with the 2008 model and consumes only 90 kWh per year, which is said to be the world's lowest power consumption level.

A high-speed drive technology for LED backlight, developed by Panasonic, allows for precise control with 1000 lines of moving picture resolution, far exceeding the current models. As a result, the panel is capable of reproducing fast-moving pictures with unparalleled clarity and high contrast ratios that are close to that of PDP panels.
