LG says its new 'Dream OLED' tech cracks the pesky problems that prevent OLED gaming panels being brighter and lasting longer
As stunning as OLED display tech is, it has plenty of problems. Limited full-screen brightness and panel degradation known as burn in are probably the two most obvious. Even the very latest and greatest OLED monitors, such as the LG UltraGear 32GS95UE are not immune. But perhaps not for much longer.
When you dig down into the details, OLED's shortcomings can often be traced directly or indirectly to limitations involving blue OLED subpixel technology. The problem with blue OLED tech is that it's much less efficient than red and green, the other two primary subpixel colors.
That means that at a given power, blue OLED produces less light than red or green. Conversely, it uses much more power and produces much more heat at comparable brightness. Fix the blue OLED problem and you fix OLED tech more generally.
Well, that's what LG claims to have done with its new «Dream OLED» panel technology (via ET News). The innovation involves a new panel utilising so-called blue phosphorescence.
Previously, blue OLED technology was restricted to less efficient fluorescent emission tech, while red and green OLED could be manufactured with more efficient phosphorescence emission.
In fact, the new LG panel reportedly uses a dual-stacked technique with both phosphorescence and fluorescent blue OLED in an effort to achieve both better efficiency and longevity.
Of course, the detailed implementation of such a technology is complicated. Neither LG nor Samsung, the two main players in OLED panel tech, actually implement a pure OLED RGB substructure. LG's WOLED panels have an all-white OLED emission layer that is then passed through RGB filters, while Samsung actually has all-blue OLED emission which then excites an RGB quantum dot layer.
