About TCL

TCL is America's fastest growing TV brand and the third largest TV manufacturer in the world, and a Roku partner. As a globally trusted leader, TCL sold more than 20 million TVs worldwide last year which ranks us among the largest TV brands in the world. With the development of our increasingly innovative products, TCL is solidifying ourselves as a true world leader in reliable and affordable televisions. Their partnership with streaming leader Roku has received huge industry and consumer acclaim. WIRED called the TCL Roku TV "the first Smart TV worth using." In 2017, PC Mag and NY Times Wirecutter both selected TCL's TVs as the best of the year and they have been consistently one of the best reviewed TVs by consumers on Amazon.com and other leading online retailers. And this year, TCL is excited to build on its award-winning TCL Roku TV lineup.
