The 47LG90 is LG's flagship LCD television for 2008. First rumored in 2007 and then shown at CES 2008 the LG90 uses an array of 128 Light-Emmiting-Diodes (LEDs) to locally dim different parts of the TV for an improved contrast ratio, and lower power usage. Traditional LCD tvs use one backlight for the entire picture meaning that any changes to the brightness of the backlight affects the entire image. Local dimming allows the system to reduce the backlight on parts of the screen that have darker content and turn the brightness up on brighter areas of the image. Being the flagship model the 47LG90 contains many of the same features as the premium LG70 series including a 1080p native resolution and a 120Hz mode. Note: The 47LG90 was previously known as the 47LG75.

Intelligent Sensor - this is the marketing name for the light sensor that automatically adjust the resulting picture on the television depending on the lighting conditions in the room.
USB2.0 port - connect a USB mass storage device to the television to access stored images and music. Format support is limited, so this isn't a replacement to a full digital media box or computer.
Invisible Speaker System - LG has done away with traditional speaker drivers and instead places actuators inside the bezel that surrounds the panel itself. LG claims this creates a "wall" of surround sound.
Clear Voice - the television dynamically enhances the audio frequencies used in human dialog in an attempt to make voices clearer even during scenes with loud background noise or music.
SimpleLink Connectivity - when the TV is hooked up to other LG devices through HDMI that support the same SimpleLink technology, you can control them directly from the TV itself.
1080p support - The sets support 1080p content at 60Hz/30Hz/24Hz through both HDMI and Component inputs.
