Sharp has announced the new AQUOS DH77 series, the latest addition to its range of full HD LCD TVs with 100-hertz technology.

Said to come in at the top end of Sharp's AQUOS LCD portfolio, the DH77 series will be available in 32-inch, 42-inch, 46-inch and 52-inch sizes.

A notable feature of the new TVs is the "green eco-button" on the remote control that Sharp says lets viewers reduce the energy consumption of the TV.

This eco-control button lets viewers directly operate the "Energy Save Mode" without having to navigate the menus.

This decreases power consumption while the TV is being watched, while the "Optical Picture Control" tech is said to further reduce power consumption by automatically adjusting the backlight brightness according to lighting in the room.

The LCD TVs in the DH77 range come with a 50,000:1 contrast ratio, Sharp's "Natural Clear Panel" that's said to produce high quality, clear images, three HDMI inputs and a USB port.
