No. 16/100,951, filed Aug. 10, 2018 which is a continuation of U.S. patent application Ser. No. 15/728,411, filed Oct. 9, 2017 which is a continuation of U.S. patent application Ser. No. 14/878,676, filed Oct. 8, 2015, the entire contents of which are incorporated herein by reference for all purposes.
Large displays are becoming increasingly popular and are expected to gain further traction in the coming years as Liquid Crystal Displays (LCD) get cheaper for television (TV) and digital advertising becomes more popular at gas stations, malls, and coffee shops. Substantial growth (e.g., over 40%) has been seen in the past several years for large format displays (e.g., >40 inch TVs), and consumers have grown accustomed to larger displays for laptops and Personal Computers (PC) as well. As more viewing content is available via mobile devices such as TV, internet and video, displays in handheld consumer electronics remain small (<6 inch) with the keyboard, camera, and other features competing for space and power.
Additionally, smart lighting is emerging as a large opportunity within the current $80B lighting market, where sensors and connectivity are introduced into the light source, as well as dynamic features related to the illumination.
