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


LG Display has unveiled its next-generation OLED technology dubbed “OLED EX,” which “should improve brightness by up to 30 percent compared to conventional OLED displays,” the company said. That could help address OLED’s biggest shortcoming besides mini-LED technology, which is a lack of overall brightness.

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

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

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 screen’s energy input to more accurately display the details and colors of the video content being played.” .”

The company has also upgraded its designs by reducing the thickness by 30 percent and the bezel size from 6 to 4 mm on 65-inch OLED displays. The company hasn’t said when it plans to release the technology, but it noted that OLED sales jumped 70 percent last year, despite a 12 percent drop in the global TV market. “With our new OLED EX technology, we aim to deliver even more innovative, high-quality customer experiences through the evolution of our OLED technology, algorithms and designs,” said Dr. Oh Chang-ho from LG Display.
