The technology Web site said Sunday paper-thin, organic light-emitting diode sets were coming out that had screens "large enough for real-world use."
"Don't expect either of these TVs to be cheap when they hit the market," CNET said. "But make no mistake, OLED is in your future."
Most impressive was an OLED set unveiled by LG, which boasted a 55-inch screen that was only 4 millimeters thick and was held together by a 1 millimeter bezel.
The televisions were seen as just one of the gems on display at the sprawling trade show, which is considered the largest annual trade show in the United States. There was a flood of tablet computers on display; however, CNET noted they could face a tough market as consumers await the spring release of the next iPad.
There were also gadgetry goodies such as wireless DVR recorders making their debut along with 3D printers and 4G smart phones. CNET said new Android phones and laptops seemed to be relatively scarce.
