LAS VEGAS (AP) — Panasonic is showing off a prototype TV that combines the two hottest technologies at this year’s gadget show in Las Vegas: organic light-emitting diodes and ultrahigh definition.

The president of the Japanese electronics company, Kazuhiro Tsuga, showed off the prototype during a keynote speech on Tuesday, the opening day of the International CES. OLED TVs are hard to manufacture, and Tsuga didn’t mention any plans for commercialization.
