Princeton Japan has announced PTV-WWTV7 – portable 7 inch LCD TV. It is powered via onboard Lithium Ion battery which lasts for 3 hours or AC adapter. The TV is waterproof and can be used in the bathroom and the kitchen. Though the idea of a portable LCD is great but the main problem is that you need TV out sockets in every room, but this is not the case with this baby. The TV comes with a seperate tuner unit you plug it to your TV jack, DVD player etc and it transmits wirelessly using Wi-Fi (IEEE802.11a) upto 30 meters. The LCD has a resolution of 480 x 234 dots and includes 2 channel stereo speakers.
