Samsung Electronics and LG Electronics say their curved TVs will get bigger and sport sharpness four times that of regular HD television sets.
The world's two largest TV makers will display ultra-HD TVs with curved screens that measure 105 inches diagonally in Las Vegas next month, they said in separate statements on Thursday.
The South Korean TV makers began selling curved TV sets earlier this year, made with advanced displays called OLED, measuring 55 inches (139cm).
The upcoming premium TVs will be made of LCD panels packing more than 11 million pixels, 5120 pixels wide and 2160 pixels high. But not much video content is available for the ultra-HD TV sets.
TV makers hope the launch of the new hardware technology will fuel the growth of content. Japan's Sony Corp, among the industry players betting that the ultra-HD images will become the new standard, is working on both gadgets and movies in ultra-HD, also known in the industry as 4K.
Asian TV makers are trying to excite shoppers with new display technology but limited video content in ultra-HD resolution and price tags will likely limit their appeal. Samsung and LG kept mum on prices.
