These micrometer-scale LEDs are transferred onto tile-like modules, permitting for a show of varied shapes and probably any dimension. Samsung additionally sells more TV-like MicroLED shows at preset sizes. However, sadly for many of us, since MicroLED remains to be a brand new and expensive know-how, it’s wildly costly, and these shows price more than most vehicles. (Assume over $100,000.)
