Panasonic LED Backlighting Techniques

LED-LCD televisions have white LEDs that are arranged around the inside frame of
the TV along with a special light diffusion panel designed to spread the light evenly
behind the LCD panel. The result is a uniform color range throughout the screen.
The technology also allows for thinner panels. IPS panels deliver a 178° wide
viewing angle and bright, clear images from most any location in the room, thereby
increasing the viewing angle.
Panasonic's top of the line VIERA LED-LCD D2 series features two 1080p Full HD
models - TC-L37D2, a 37-inch class (37" measured diagonally) HDTV and the TC-
L42D2, a 42-inch class (41.6" measured diagonally) HDTV. The LED method of
backlighting the LCD panel allows for the HDTVs to become extremely thin and
offers a wider color gamut than traditional back-lit LCDs, which use fluorescent
bulbs to provide the light source. Combined with the IPS panel, the viewing angle is
improved, contrast is also improved and there is lower power consumption. The D2
series also features the proprietary Universal Dock for iPod®; the VIERA Image
Viewer™ to view digital still JPEG photos; VIERA Link™, - a technology that
utilizes HDMI-CEC (Consumer Electronics Control) and allows a consumer to
operate all VIERA Link™ compatible A/V components using only the TV's remote
control; a PC input; 24p Smooth film; 120Hz motion picture Pro 4; four HDMI
connections and Clear Panel.
