On Tuesday, Samsung showed that LCD panel prices dropped more than expected due to expanded capabilities of Chinese competitors, while demand from large buyers of their flexible OLED monitors, commonly used in high-end smartphones, also declined.
Mehdi Hosseini, senior equity research analyst at Susquehanna Financial Group, wrote on Monday that weak smartphone industry demand pushed Samsung's display unit, especially OLED panels.
OLED panels "pop" colors more than on a traditional LCD panel, meaning images, videos and games can look much more true to life.
"In fact, our checks indicate that Apple has dramatically cut back on the purchase of" flexible "OLED panels, which they try to keep the channel inventory to a minimum," Hosseini said. Samsung is a large OLED display provider for the iPhone manufacturer.
He added that he expects Samsung's display revenue to fall by about 50 percent in the quarter, worse than previous expectations of a 30-40 percent decline. Still, a bright spot for Samsung is the latest flagship, Galaxy S1
"We expected OLED display shipments to increase into the June quarter, but the size still tracks below expectations," he said.
The Samsung shares fluctuated 0.88 percent in morning trading, falling behind the broader Kospi index on positive territory on Tuesday morning.
