LG Display Successfully Developed the World's First 88-inch 8K OLED Panel

On January 1, 2018, LGDisplay announced that it has successfully developed the world's first 88-inch 8K OLED panel, again proving and consolidating its leading position in the global display industry.

As the world's first large-size 8K OLED display product, the resolution of the panel reached 7680×4320, and the number of pixel points reached 33 million. Its resolution is 4 times that of current 4K Ultra High Definition (UHD) TVs and 16 times that of Full HD (FHD) TVs, and it can provide users with stunning and clear images.

LGDisplay Successfully Developed the World's First 88-inch 8K OLED Panel

As the largest size and highest resolution high-end product in OLED TV panels, the 8K era is approaching. This 88-inch 8K OLED panel will undoubtedly become another milestone in the history of OLED and become a leader in the high-end TV product market.

Leading the ultra-high resolution market

In general, the higher the resolution of the display panel, the finer and more vivid the displayed image quality. However, as the pixel size of the picture becomes smaller, it is difficult for the pixel components to be reduced in the same proportion, so the aperture ratio of the panel will be reduced accordingly, which means that the efficiency of light passing through the panel is reduced, so that it is difficult to achieve a high display. brightness.

Since OLEDs have self-luminous characteristics and do not require a backlight source, each pixel of the OLED can control its own brightness. Therefore, brightness does not decrease due to a decrease in the aperture ratio, and 8K ultra-high resolution display can be realized very easily. In addition, LGDisplay's unique innovative panel design, meticulous process and compensation technology have also become a further guarantee of 8K display technology. It can be expected that OLEDs will continue to lead the market for oversized, ultra-high resolution displays.

In contrast, due to the non-self-luminous characteristics of the LCD, as the pixel size becomes smaller, the light transmittance decreases rapidly, so it is only possible to rely on the backlight source to ensure the performance. If the LCD wants to achieve the same brightness as UHD, the cost and power consumption of the backlight will increase rapidly.

Create more detailed image quality

As we all know, compared with LCD, OLED can present a perfect black, with infinite contrast, excellent wide viewing angle and more vivid colors; at the same time, OLED TVs have also received great recognition in the Ultra High Definition (UHD) TV market. In television reviews conducted by consumer magazines in 12 countries including the United States, Europe, and Australia, OLED TVs took first place and were rated as the best TV products.

DisplayMate, an authoritative display expert group in the United States, once praised: “OLED TVs are nearly perfect in terms of picture quality and have the best color accuracy, brightness accuracy, and picture contrast compared to other TVs currently tested.”

Japanese quality expert Reiji Asakur (Vice President of the Japan Society for the Study of Quality) said in an OLED white paper published by the most authoritative audiovisual magazine HiVi: "Achieving ultra-high resolution beyond 4K, through High contrast shows fine picture quality, OLED TV is the best choice."

8KOLED technology has further improved the picture quality of television. OLEDs can control 33 million pixels independently without the need for a backlight source, and can maximize the use of 8K ultra-high resolution to achieve fine picture quality, giving consumers a more vivid and realistic viewing experience.

Maximize the synergy between design and picture quality

The form and thickness of the panel has always been an important factor in TV design considerations. In terms of morphology, OLED panels have achieved various display methods such as curling, folding, two-sided, and embossing, exhibiting unlimited design freedom. In terms of thickness, thanks to the self-illumination advantages of OLEDs, the OLED panel can still maintain a light and thin design while the display resolution is increased to the 8K level. On the contrary, the LCD panel must achieve the 8K resolution and have the normal viewing requirements. Brightness requires a significant increase in the backlight source, resulting in an increase in panel thickness and volume.

From the technical point of view, for LCD, at 4K resolution, the LCD panel can achieve 4K display by adding edge backlight to the edge of the screen. The panel thickness will not increase; and at 8K resolution, To achieve the brightness and image quality beyond the 4K level, you need to use the direct backlight mode, that is, adding backlight source behind the panel to achieve normal display, the panel thickness and volume will inevitably increase.

It can be seen that in the 8K era, OLED will continue to lead the ultra-high-resolution market with more refined picture quality and thinner design.

"As the pioneer of the large-size OLED display market, LGDisplay has successfully developed the world's first large-size 8K OLED panel. While leading the arrival of the 8K display era, it further proves the technical advantages of OLED." Vice President of LG DisplayCTO Jiang Renbing said: "The future, LGDisplay will continue to accelerate the development of OLED products and continue to provide the differentiated products needed for customers and markets."

It is reported that LGDisplay will set up a special exhibition hall at Consumer Electronics Show (CES) held in Las Vegas, USA from January 9th to December 12th, 2018 to showcase innovative products including 8K OLED products.

※ Resolution: Resolution refers to the precision of the picture or font represented on the screen, which is reflected in the number of pixels in the screen. The 8K TV can display a resolution of 7680×4320 pixels, which is 16 times that of a FullHD TV and 4 times that of a UHD (4K) TV.

* Opening ratio: Opening ratio refers to the ratio between the area of ​​the portion through which light can pass and the area of ​​each sub-pixel after removing the wiring portion and the transistor portion of each sub-pixel (usually hidden by a black matrix). The higher the rate, the more efficient the light passes through.
