LG Display has reportedly asked rival Samsung Display to join the race for large-sized organic light-emitting diode (OLED) panels to beat Chinese companies in the sector. The Korea Times reports that LG Display CEO has officially called for cooperation between the to companies.

"Samsung Display will join with LG," LG Display CEO and Vice Chairman Han Sang-beom said on the sidelines of a meeting between CEOs from big companies and the trade ministry in downtown Seoul, Wednesday. "I believe this issue is a matter of timing."

Han added that LG Display plans to invest up to 4 trillion won focusing on larger OLED panels for televisions.

The company executive said the its latest P10-dubbed OLED plant in Paju, the city near the inter-Korean border, will be the largest OLED plant in the world. It is expected to be operational from June 2018 and will supply small and large OLED panels to top clients including Apple.

Samsung Display said the Samsung Group's display affiliate "is trying hard to fine-tune OLED technologies."

"Samsung Display is trying its best to develop OLED technologies," CEO Park Dong-geun said. "We are reviewing the marketability of the OLED TV market. However, no decisions have been made so far," Park said, adding the timing to start mass-production of OLED TV panels is yet to be finalized.

Until now, Samsung has been cautious to invest in the production of larger OLEDs, and has been focusing on smaller OLEDs to be used in the Galaxy device lineup.
