BOE has filed patents for a new transparent OLED technology that could challenge LG's dominance in the market. The innovation addresses key drawbacks of current transparent displays, including low brightness, poor light transmittance, and high manufacturing costs.
Patents reveal IZO cathode and COE structure
The technology uses an IZO (Indium Zinc Oxide) transparent cathode combined with a COE (Color Filter on Encapsulation) structure. This combination eliminates additional layers, making panels thinner and more efficient.
BOE's approach improves brightness and light transmittance while reducing manufacturing costs, according to the patent filings. The IZO cathode and COE design also enhance color reproduction.
Current transparent OLEDs rely on metal cathodes that limit light transmission and require extra layers, driving up costs. BOE's solution could simplify production and lower expenses, potentially breaking LG's monopoly in the transparent OLED market.
The patents are a sign of BOE's push into premium display technology. The company is known for LCD and OLED panels but has not yet commercialized transparent OLEDs at scale.
BOE's transparent OLED technology remains in the patent stage with no announced timeline for production. The filings show a clear intent to compete in this niche but growing segment.
