LG Display, LG Electronic’s display panel manufacturing sister company, announced this week that it has developed the world’s first 88-inch 8K OLED display, which will be shown at CES 2018 in Las Vegas next week.

The OLED display is said to have 33 million pixels (7680×4320) – 16 times more than FHD (1920×1080) and four times more than UHD (3840×2160).

LG Display made the announcement early to get the jump on competitors, who are reportedly also planning to make 8K display technologies a part of their announcements at the consumer technology showcase.

“The successful development of the world’s first 8K OLED display is a milestone for the 8K era and underscores the exciting potential of OLED,” said In-Byung Kang, LG Display Chief Technology. “OLED is clearly a next-generation technology leader and for this reason, LG Display is accelerating its research and development into OLED so that we can provide differentiated products to customers and markets.”

The company did not say when it expects to have an 88-ink 8K television in the market, but at the least the earliest applications are expected to be targeted at commercial and signage markets.

The 8K panel is said to deliver ultra-high resolution without compromising brightness. LG developed the technology by reducing the size and aperture ratio of each pixel, which ordinarily diminishes brightness with back-lit technologies.

The aperture ratio is the ratio of the area that light can pass through as it is not covered by the black matrix and the wiring portion (electric circuit) in the entire area of the pixel. Shrinking the aperture ratio reduces brightness.

The company explained that as OLEDs are self-emissive and therefore less affected by aperture ratio, they are optimal for 8K panels. On the other hand, non-emissive LCDs should improve the performance of their back light units when achieving higher resolution in order to compensate for the drop in aperture ratio and brightness. This leads to an increase in power consumption and material costs.

The 8K OLED displays, which do not require backlight units, are able to maintain their slimmer design. This contrasts with 8K LED-LCDs that get heavier and thicker from the need to place backlight units directly behind the panels to achieve the same level of brightness and picture quality as 4K products, LG Display said.

LG Display said the demonstration of its 88-inch 8K OLED panel proves that the company “is set to lead the extra-large and ultra-high resolution panel market,” even as some of the first large format OLED panel manufacturing competitors move toward the development of their own OLED manufacturing facilities.
