LG Display Debuts Blue PHOLED Panel With 15% Less Power Use

LG Display Achieves Breakthrough in Blue Phosphorescent OLED Technology
LG Display has achieved commercialization-ready performance for its blue phosphorescent OLED panel. This marks a critical milestone in OLED advancement, especially for IT applications like smartphones and tablets. The new panel combines phosphorescent and fluorescent elements in a hybrid design. This innovation positions LG Display as a leader in next-generation OLED efficiency. The company will showcase the technology in compact displays at SID Display Week 2025.

Hybrid OLED Structure Reduces Power Consumption by 15%
The new OLED panel features a hybrid two-stack Tandem structure with distinct emission layers. Blue fluorescence resides in the lower stack, while blue phosphorescence powers the upper. This dual-layer configuration differs from legacy OLEDs, which rely solely on blue fluorescence with red and green phosphorescent layers. As a result, LG’s panel cuts power usage by about 15%. This gain comes without compromising display stability.

Blue Phosphorescence Significantly Enhances Light Efficiency
Blue phosphorescence offers four times the light efficiency of traditional fluorescence. Fluorescent layers convert only 25% of electrical energy into light, while phosphorescent layers achieve 100%. LG Display’s hybrid approach merges the reliability of fluorescence with the energy efficiency of phosphorescence. This balance enables longer battery life in portable devices. It also supports sustainable tech development through reduced energy consumption.

LG Display Collaborates with Universal Display Corporation for OLED Innovation
The success follows an eight-month collaboration with Universal Display Corporation. Together, the companies advanced blue phosphorescent materials to a production-ready state. This partnership played a key role in realizing LG’s “Dream OLED” vision. The milestone represents a foundational step toward fully phosphorescent OLED displays. It also underscores LG’s commitment to cutting-edge display solutions.

Upcoming Public Demonstration at SID Display Week 2025
LG Display plans to debut the blue phosphorescent OLED at the SID Display Week in San Jose. The event begins on May 11, 2025, and will draw global attention from tech leaders. Demonstrating the two-stack Tandem OLED in small and medium formats highlights LG’s focus on mobile and IT devices. The display will serve as proof of concept for future commercial applications. This public unveiling signals the start of a new phase in OLED development.

Has the Dream OLED TV Finally Arrived? Not Yet, But We’re Getting Closer

LG Display’s blue phosphorescent OLED technology marks progress, but it’s not TV-ready.
The company plans to showcase this innovation at SID Display Week in a small- to medium-sized panel. This format targets IT devices such as smartphones and tablets, not televisions. Despite its readiness for mass production, the panel remains confined to prototypes.

Blue PHOLED technology still lacks full-scale application in premium OLED TVs.
LG Display confirmed it has completed commercialization verification with Universal Display Corporation (UDC). However, its implementation remains limited to smaller displays. Larger TV panels require higher light efficiency and durability, which this version cannot yet deliver.

Blue phosphorescent OLED has been under development for years.
LG Display previously announced the successful development of a blue PHOLED-based panel. This layer significantly boosts efficiency compared to traditional OLED emitters. But a gap remains between prototype success and full TV-scale deployment.

The current hybrid PHOLED approach does not yet achieve the “Dream OLED” benchmark.
Today’s iteration combines traditional fluorescent and phosphorescent materials. While it improves efficiency, it falls short of the ideal light output and lifespan for TVs. Full phosphorescence across all subpixels remains the goal for next-generation OLED panels.

For now, LG’s “four-stack” OLED panel leads in TV performance.
Found in the new LG C5 OLED, this design uses discrete red, green, and blue emitters. The result is superior color accuracy and peak brightness without relying on blue phosphorescence. It will likely remain the top-tier solution for OLED TVs throughout 2025.
