In recent developments, South Korean display manufacturer LGD has made a significant breakthrough by successfully developing 88-inch 8K OLED panels. These cutting-edge displays are set to be showcased at the CES International Consumer Electronics Show in Las Vegas, USA, from January 9th to 12th, 2018. This marks a major step forward in high-resolution display technology and highlights the growing competition in the global TV market.
Generally, higher resolution leads to sharper and more vivid images. However, as pixel sizes shrink, it becomes increasingly challenging to maintain the same aperture ratio, which affects light transmission efficiency and can lower brightness levels. Unlike traditional LCDs, OLEDs are self-luminous and don't require a backlight. This means each pixel can independently control its brightness, allowing for excellent brightness even with smaller pixels. As a result, achieving 8K resolution on OLED screens is much more straightforward, making it an ideal choice for ultra-high-definition displays. LGD's advanced panel design, manufacturing process, and compensation technologies have further solidified their position in this emerging field.
What exactly is 8K? If 2017 was the year of OLED in the television industry, then 2018 is shaping up to be the year of 8K. The concept of 8K TVs was first introduced at CES 2013 by Sharp, with a resolution of 7680×4320—four times that of 4K and 16 times that of 1080p. In August 2017, Sharp launched the world’s first consumer-grade 8K LCD TV, priced around 69,000 yuan. This marked a new era in home entertainment.
An 8K TV boasts over 33 million pixels, offering four times the detail the human eye can perceive. But it's not just about clarity—8K TVs also improve picture precision, color gamut coverage, color depth, and frame rates. For instance, during the Rio de Janeiro Olympics last year, Japan’s NHK broadcasted live footage in 8K, delivering an immersive visual experience that left viewers in awe. The company has since announced plans to use 8K for the 2020 Tokyo Olympics, signaling a strong commitment to the technology.
As the TV industry evolves, high resolution has become a key driver of innovation. In December 2017, BOE (BOE Technology Group) launched the world’s first 10.5-generation TFT-LCD production line in Hefei, capable of producing large 65-inch and 75-inch panels efficiently. The company is also preparing to deliver 75-inch 8K60Hz and 75-inch 8K120Hz displays to major partners like Samsung, LG, Sony, Hisense, Xiaomi, and Haier. While 55-inch 4K TVs are already mainstream, 8K TVs over 75 inches are becoming a natural progression in display technology.
From a market perspective, 4K penetration in China has surpassed 70%, but globally, it's still under 30%. There remains an imbalance in product size, pricing, and availability. Looking ahead, 8K TVs are expected to target the high-end market in Europe, the U.S., Japan, and China.
Previously, there were debates about whether 8K and OLED would compete. However, with OLED now entering the 8K space, the TV industry is likely to use 8K as a new marketing highlight in the coming years. This shift could redefine how consumers view next-generation displays and accelerate the adoption of ultra-high-definition technology.
