World's first 55‐inch OLED TV has been developed and recently launched mass production with excellent display image quality. We employ IGZO TFT backplane and white OLEDs with WRGB pixel design. Those technologies enable panel size scalability as well as mass production with lifetime reliability. For commercializing large‐size OLED TV, the issues and challenges on panel design and driving, including LG Display's recent experience will be presented.

“…White organic light-emitting diodes (WOLEDs) have attracted great interest by researchers as eco-friendly lighting sources as an alternative to a mercury containing fluorescent lamp and is a strong candidate as a large-scale process for OLED TV. 1,2 The elimination of the fine metal mask (FMM) is a big advantage of WOLEDs with a color filter (CF) in the manufacturing process. However, it has been challenged due to low efficiency and lifetime.…”

Abstract— A 15‐in. HD panel employing two‐stacked WOLEDs and color filters for which the color gamut can be as high as 101.2% (CIE1976) and the power consumption is 5.22 W. The WOLEDs exhibit a current efficiency of 61.3 cd/A and a power efficiency of 30 lm/W at 1000 nits and their CIE coordinate is (0.340, 0.334). A 15‐in. RGBW panel was investigated to verify the electrical and optical performance compared to that of a 15‐in. RGB TV made by using FMM technology. The characteristics of the 15‐in. RGBW panel are comparable to those of the 15‐in. RGB panel. Color filters combined with WOLEDs is a possible patterning technology for large‐sized OLED TV, which surpasses the limits of fine‐metal‐mask technology.

We have developed a two-stacked white OLED based on bottomemission structure for large-sized display. It consists of one unit emitting fluorescent blue and the other unit emitting phosphorescent yellow (two-dopant of red and green) in a host layer. In order to improve the performance of the WOLED, we adopted new non-cabazole compound as a hole transporting layer with high triplet energy level and akali-metal doped charge generation layer. In addition, we employed new greenish yellow dopant instead of previous green dopant to enhance the lifetime of the phosphorescent stack. The resulting device exhibits 61.3 cd/A of current efficiency, 30 lm/W of power efficiency, and 6.4 V of driving voltage of at 1000 nit where its CIE coordinate is (0.340, 0.334). ) of the device is estimated more than 130,000 hrs at 1000 nit. We also fabricated 15-inch HD panel employing the two-stacked WOLED and color filter.
