Hitachi, Ltd. exhibited a 32-inch LCD TV that is only 1.9 cm thick. It was shown in a special theater-style room, which was decorated with the words "Next-Generation Thin-Panel TV," inside the booth. There was a line of visitors waiting to enter the room.
One of the key points in the reduction of thickness is the layout of the parts. The parts, such as the signal processing circuit, are mounted in the base, not in the back of the panel. The display is simply composed of the panel mounted with the package and the essential substrates.
The display and the base are connected by an arm and the wires are laid out inside the arm. This method of reducing thickness is similar to the one incorporated by Sony, which announced an organic EL on October 1.
Another key point in the reduction of thickness is the thinning of the panel itself. "The reduction of the back light thickness made a big difference," according to Hitachi. Details on the back light were not disclosed.
The resolution of the panel, which is manufactured by IPS Alfa Technology Ltd., is 1366 x 768. "The prototype does not have holes for releasing heat on the back. This is because the IPS panel used has a high aperture ratio," according to Hitachi.
Hitachi, Ltd. plans to start mass production in 2009. The prototype is not equipped with a TV tuner.
