As the global display industry evolves, LED displays gradually shift from a singular pursuit of physical performance toward a return to energy-efficiency value. In the early stages, competition centered on peak brightness, color saturation, and ever-finer pixel pitch. Today, in the era of ultra-high-definition (UHD) displays, heat generated by high power consumption has become a growing constraint—creating “thermal anxiety” that limits further performance breakthroughs. In recent years, companies including Leyard, Unilumin, Ledman, and Absen have promoted &…
