LG Display’s research division received the Distinguished Paper award at the Society for Information Display conference, currently being held in Los Angeles, California. Led by researcher Shin Hong-jae, a team from the firm presented a new technique applied to the production of very large OLED screens 80 inches and more, in an article entitled A Novel Ultra Large Size OLED Display for Premium TVs (a new ultra-wide Oled screen for high-end televisions).
Indeed, Oled technology suffers from a problem of uniformity when the screen exceeds a certain size. By improving the performance of individual diodes and reducing the size of the display frame, these researchers were able to produce large panels displaying a uniform image. LG Display could thus offer Oled 4K versions of 83 and 97 inches, in addition to the 88-inch 8K panel already marketed since 2018.
The company also highlighted its META technology, which combines the use of microlenses and a specific algorithm to increase the brightness of Oled panels. We tested the LG 65G3, the first television with this technology, and measured a peak brightness of 1460 cd/m² in Filmmaker mode, compared to only 998 cd/m² for the LG 5G2 from 2022, a gain of 50% one generation to another. Please note that META technology is not available on TVs over 77 inches. The LG 83G3 does not have it, for example, and its peak brightness is therefore lower than that of the 55, 65 and 77 inches in the same range.
The second article, titled High-Resolution Active-Matrix Micro-LED Stretchable Displays, written by Jung Hae-yoon and his team, focuses on the creation of stretchable screens based on MicroLED. These stretchable screens go further than the current generation of foldable OLED screens, as they can be bent, stretched and twisted into almost any shape.
LG Display research team successfully developed a prototype 12-inch stretchable MicroLED display, which can be stretched up to 20% more. SID has recognized that this research will significantly improve the resolution, flexibility and readability of stretchable display technology, believing it to represent significant progress.
Yoon Soo-young, chief technology officer at LG Display, said this latest work is just the beginning and his research is likely to progress even further in the coming years.
