[ICEL 2018] What are the future challenges for LG Display to improve OLED TV performance?

At ICEL 2018, held at Jeju International Convention Center from Oct. 15, Soo-Young Yoon, Vice President and Head of LG Display Laboratory, presented the challenges for the OLED TV performance improvement and price reduction

Yoon said “In 2018, the future prospects of OLED TVs have changed more positively compared to that in 2016. In 2013, only LG Electronics was an OLED TV set maker. The number of OLED TV set makers has steadily increased; ten in 2016, and fifteen in 2018. Many TV set makers are choosing OLED. ”

He added that although OLED TV is on the track of success with lots of improvement, it has to be further developed. The challenge is the improvement for high brightness, color reproduction rate and with the development of 8K resolution. Also he mentioned that the price reduction is to be necessary.

Yoon explained that the development of components such as driver IC and controller is an important task to develop 8K OLED TV. In order to improve the brightness, color reproducibility, and lifespan, TADF and phosphorescent Blue are to be good alternatives for improving the RGB emitting materials. The enhancement of out-coupling is also important.

In addition, he referred to the solution processed OLED as a technology, to compete against LCD TV price, with the necessity of developing inkjet equipment, process, and soluble materials. For this, it is required to develop the ink jet equipment and shorten the process time for mass production, but the performance and reliability of the soluble materials will be more important.
Finally, he commented that the company will focus on 8K OLED TV and rollable OLED TV with the improvement of brightness until 2020. After 2022, the company will develop the OLED TV which has an enhanced brightness of 300 nits or more, a color gamut that satisfies BT.2020, and a lifespan of more than 30,000 hours.
