LG Show introduced “commercialization level” efficiency of a blue phosphorescent OLED panel
The brand new panel is a hybrid fluorescent/phosphorescent design that consumes about 15% much less energy than typical OLED shows
The brand new tech will likely be demonstrated in a “small and medium-sized panel that can be applied to IT devices such as smartphones and tablets”
Korean producer LG Show right now introduced it has efficiently verified the “commercialization level” efficiency of blue phosphorescent OLED panels.
The announcement comes eight months after LG Show partnered with OLED know-how firm Common Show Company on the event of blue phosphorescence, a needed subsequent step in making a “Dream OLED” show.
Based on LG Show’s launch, the corporate was in a position to make the know-how mass production-ready utilizing a “hybrid two-stack Tandem OLED structure, with blue fluorescence in the lower stack and blue phosphorescence in the upper stack.” This strategy differs from earlier OLED show panels, which use a blue fluorescent layer paired with pink and inexperienced phosphorescent layers.

The difficulty with utilizing a fluorescent layer in OLED panels is that it gives solely 25% gentle effectivity in comparison with a phosphorescent layer, which gives 100% gentle effectivity. LG Show’s hybrid strategy modifications issues up in “combining the stability of fluorescence with the lower power consumption of phosphorescence.” By doing so, it “consumes about 15% less power while maintaining a similar level of stability to existing OLED panels,” in keeping with the corporate.
LG plans to display its blue phosphorescent OLED panel with two-stack Tandem know-how at SID Show Week, an occasion that will get underway on Might 11, 2025 in San Jose, California.
Has the Dream OLED TV lastly arrived?
Whereas LG Show’s announcement is intriguing, the blue phosphorescent OLED panel it plans to show at SID Show Week will showcase the know-how in “a small and medium-sized panel that can be applied to IT devices such as smartphones and tablets.”
Which means the present iteration of the tech, whereas mass production-ready (LG Show says it has “completed commercialization verification with UDC”) stays in prototype type, and isn’t prepared for introduction in bigger shows comparable to one of the best OLED TVs.
In the meantime, LG Show’s “four-stack” OLED show panel, a design that doesn’t depend on blue phosphorescent tech, hybrid or in any other case, however as a substitute makes use of separate pink, inexperienced, and blue parts to reinforce colour purity and enhance brightness, will be discovered within the spectacular new LG C5 OLED, top-of-the-line TVs to reach to date in 2025.
We count on this panel to stay the innovative for OLED TVs for a while to come back, whereas the brand new hybrid two-stack Tandem OLED construction with blue phosphorescence will get developed for gadgets like telephones and tablets.
