The source added the company will likely unveil 77-inch rollable OLED displays, as the size is the largest one that the company is currently capable of producing.
For now, LG Display produces 55-, 65- and 77-inch OLED displays to be used in manufacturing TVs from LG Electronics.
LG Electronics declined to comment on details over the company's plan to promote OLED TVs at the CES.
Rollable TVs, as the name implies, uses displays that are flexible enough to carry around, reducing burdens of space restrictions. But it does not mean that the TVs can be foldable.
Last year, LG Display unveiled an 18-inch rollable OLED display using a paper-thin panel. But as the 18-inch display was rolled up to a radius of three centimeters, the upcoming devices will not be fully rollable.
