LG Display says its new ‘OLED EX’ technology increases brightness by up to 30 percent


LG Display has discovered its next-generation OLED technology, dubbed “OLED EX,” which should “boost brightness by up to 30 percent compared to conventional OLED displays,” the company said. This could help correct the biggest shortcoming of OLED mini LED technology, or lack of overall brightness.

As the LG Display points out, each OLED pixel emits light independently, which means it can be turned on or off completely. This allows TVs to display perfect blacks without “blooming” on LED TVs, but at the same time, OLED pixels cannot achieve the same brightness levels as LEDs. Current OLED sets can display peak brightness levels of up to about 500-600 nits, while mini LED sets can reach 2000 nits and more.

To make OLED sets brighter, OLED EX (Evolution / eXperience) uses deuterium compounds to allow light-emitting diodes to emit stronger light. “When stabilized, deuterium compounds allow the screen to emit brighter light while maintaining high efficiency for a long time,” LG Display said.

OLED EX also provides improved color accuracy. It apparently uses algorithms to predict the use of 33 million OLED diodes in an 8K display, so that it “precisely controls the power input of the display to more accurately express the details and colors of the video content being played.”

The company has also upgraded its design, reducing thickness by 30 percent and frame size from 6 to 4 mm on 65-inch OLED screens. The company has not yet said when it plans to launch the technology, but noted that OLED sales rose 70 percent last year despite a 12 percent drop in the global TV market. “With our new OLED EX technology, we aim to provide an even more innovative, cutting-edge user experience through the evolution of our OLED technology, algorithms and design,” said Dr. Oh Chang-ho of LG Display.
