2、可能有一个团队，其唯一目的是要开发比LG大一英寸的78英寸的4K OLED屏幕，并在2014年国际消费电子展上展出。不幸的是，这款由LG首推的77英寸电视的规格、价格及上市信息尚不明确。以下为原文：LGs 4K OLED TV wins CES awardLG has revealed the largest4K OLED TV shown in the United States today, a television featuring a curved77-inch screen, and won a CES Best of Innovations award.TheLG Ultra H

10、concave, shiny surface that was only a little moresuccessful at reducing reflections than a flat panel. The curve also meant thatwhen we were quite off-axis part of the panel was actually obscured by the edgeof the television.CNETTV reviewer David Katzmaier suggested only half-jokingly that somewhereat Samsung there is probably a team whose sole purpose is to build a1-inch-bigger, 78-inch 4K OLED for display at CES 2014.Unfortunately little moreis known about this 77-incher as LG was mum on specifications, pricing, oravailability. /
