Recently, South Korean display manufacturer LGD announced the successful development of 88-inch 8K OLED panels, which will be showcased at the CES International Consumer Electronics Show in Las Vegas, USA, from January 9th to 12th, 2018. This breakthrough marks a significant step forward in high-resolution display technology and highlights the growing competition among global manufacturers.
In general, higher resolution leads to sharper and more vivid images. However, as pixel sizes shrink, it becomes challenging to reduce the size of pixel components proportionally, resulting in a lower aperture ratio. This means less light can pass through the panel, reducing brightness. But OLED technology overcomes this issue because each pixel is self-lit and doesn't require a backlight. This allows OLED panels to maintain high brightness even with smaller pixels, making 8K resolution more achievable. LGD's advanced panel design, manufacturing process, and compensation technology have further ensured the stability and performance of their 8K displays.
What exactly is 8K?
If 2017 was the year of OLED in the TV industry, then 2018 is shaping up to be the year of 8K. Sharp first introduced 8K TVs at CES 2013, offering a resolution of 7680×4320—four times that of 4K and 16 times higher than 1080P. In August 2017, Sharp launched the world’s first consumer-grade 8K LCD TV, priced around 69,000 yuan. Since then, 8K has gradually moved from concept to reality, with more companies investing in its development.
The high resolution of 8K TVs brings an impressive 33 million pixels, allowing for four times the detail that the human eye can perceive. But 8K isn’t just about clarity—it also improves picture precision, color gamut coverage, color depth, and frame rate. During the opening ceremony of the Rio de Janeiro Olympics last year, Japan’s NHK broadcasted 8K video, delivering an immersive and stunning visual experience. The company has since announced plans to use 8K for the 2020 Tokyo Olympics, signaling the growing importance of ultra-high-definition content.
High resolution is driving the evolution of television displays.
In December 2017, BOE launched the world’s first 10.5-generation TFT-LCD production line in Hefei, capable of producing large panels such as 65-inch and 75-inch models. These panels are not only cost-effective but also ideal for high-end displays. BOE also announced plans to supply 75-inch 8K60Hz and 75-inch 8K120Hz screens to major brands like Samsung, LG, Sony, Hisense, Xiaomi, and Haier. As 55-inch 4K TVs become mainstream, 8K TVs above 75 inches are becoming a natural progression in display technology.
From a market perspective, while 4K penetration in China has surpassed 70%, globally it’s still below 30%. There’s an imbalance in product sizes and pricing, but 8K TVs are expected to target the high-end segment in Europe, America, Japan, and China in the coming years.
Previously, some industry experts debated whether 8K and OLED would compete, but now that OLED is entering the 8K space, the TV industry is likely to use 8K as a new marketing angle in the next phase of development. With continued innovation and demand, 8K could soon become the standard for premium viewing experiences worldwide.
