在本文中，我们提出了大尺寸OLED面板的设计方案。考虑到氧化物TFT的可靠性，提出了新的像素电路来补偿TFT的阈值电压漂移，并在每个WRGB子像素中设计。此外，面板的设计理念，以改善供电进行了说明。低电阻率铜金属用于允许大的面板电流与均匀供应的电源电压。55英寸面板成功制造并展示。氧化物TFT和具有彩色层的白色OLED是OLED电视很有前途的技术。
In this paper, we suggest panel design schemes for large size OLED panel. With considerations on the reliability of oxide TFT, new pixel circuit is proposed to compensate threshold voltage shift of TFT and is designed in each WRGB sub‐pixel. Also, the panel design concept for improving power supplying is explained. Low resistivity Cu metal is used to allow large panel current with uniformly supplying power voltage. 55‐inch panel is successfully fabricated and demonstrated. Oxide TFT and white OLED with color layers are promising technologies for OLED TV.
