LG is working on a new panel technology called “Dream OLED,” which aims to address two of the major challenges faced by OLED displays: insufficient brightness and reduced lifespan.
While OLED panels have gained widespread popularity, they still have drawbacks, especially when compared to alternatives like MicroLED and Mini LED. The most significant of these is limited brightness, which can be considerably lower. Additionally, OLED displays’ durability is a concern, with the issue of burn-in occurring more frequently than desired.
These limitations are largely tied to the blue light-emitting diodes used in the panels. In the RGB (red, green, blue) standard, blue diodes are less efficient, generating less brightness and producing more heat compared to red and green diodes. This is because red and green diodes utilize more efficient phosphorescent emission, whereas blue diodes, until recently, relied on less efficient fluorescent emission.
According to PCGamer, LG’s “Dream OLED” technology breaks this barrier by incorporating phosphorescence into the blue diodes as well. LG’s innovation combines fluorescent and phosphorescent blue diodes in a stacked structure, resulting in a more efficient and durable OLED panel.
The good news is that LG is already moving forward with production plans for this new technology. The South Korean company is currently in the production evaluation phase and expects to begin shipping “Dream OLED” panels to customers within a year. However, this is only the first step, as the components still need to be integrated into monitors and TVs before reaching the market.
Despite recent advancements in OLED displays, such as the LG UltraGear 32GS95UE monitor, brightness and burn-in issues remain challenges. LG’s new “Dream OLED” panel technology, which uses a combination of phosphorescence and fluorescence in the blue diodes, could represent a significant breakthrough for the industry, offering greater brightness and resistance to burn-in.
Although it’s still unclear how fully the “Dream OLED” technology will achieve these goals, it certainly marks a significant step in the right direction. LG appears to be addressing the major challenges of OLED technology head-on, aiming to combine the brightness efficiency of LCD panels with greater durability.
