The value of LED backlighting production will fall by about 10% this year, say Taiwanese LED makers, as TV and tablet production value falls. Both smartphones and TVs will represent about 30% of production value. UltraHD TVs require between 40% and 50% more LED chips than FullHD models. Meanwhile, as 5″ becomes the mainstream smartphone size, production value for smartphone backlighting applications is expected to grow 15% – 20%.
