A novel OLED (organic light emitting diode) lighting panel, which uses a special layout design, can reduce the photolithography cycles and process costs and is more reliable. It only needs two steps of photolithography cycles, which include an ITO (InSnO compound transparent oxide) pattern and insulator pattern. There is no need for the metal bus pattern of the ordinary design. The OLED device structure is a type of red-green-blue (RGB)-stacked emitting layer that has a good color index and greater adjustability, which improves the performance of the device. This novel design has the same equipment and material requirement compared to the ordinary design, and it is very beneficial in terms of high volume and low-cost production. It uses a hyper driving method because the entire OLED lighting panel is divided into many sub-emitting units; if one of the sub-emitting units is burned out, it has no effect on the adjacent sub-emitting unit, so the reliability is markedly better than the ordinary design.
一种采用特殊布局设计的新型OLED（有机发光二极管）照明面板，可减少光刻周期和工艺成本，且更可靠。它仅需两步光刻周期，包括ITO（铟锡氧化物复合透明氧化物）图案和绝缘体图案。无需普通设计中的金属总线图案。OLED器件结构是一种红绿蓝（RGB）堆叠发光层，具有良好的色指数和更大的可调节性，从而提高了器件性能。与普通设计相比，这种新颖设计对设备和材料的要求相同，在大批量低成本生产方面非常有利。它采用超驱动方法，因为整个OLED照明面板被划分为许多子发光单元；如果其中一个子发光单元烧坏，对相邻子发光单元没有影响，因此可靠性明显优于普通设计。
