展示了世界上第一个柔性全彩色5.6英寸有源矩阵有机发光二极管(AMOLED)显示器，其顶部发射模式为不锈钢箔。利用低温多晶硅(LTPS)制作了有源矩阵背板。在不锈钢衬底上制备的p沟道多晶硅TFT的场效应迁移率为71.2cm2/vs，阈值电压为2.7V，截止电流为6.7×1013A/um，亚阈值斜率为0.63V/−。这些TFT性能使得在面板上集成扫描驱动电路成为可能。开发了一种低成本的不锈钢箔平坦化技术，以取代昂贵的化学机械平坦化(CMP)方法，这是阻碍大规模生产的最关键障碍。不锈钢箔上的全彩色柔性AMOLED显示屏由于其薄、轻、坚固和无需设计的特性，将在移动应用中具有广阔的前景。
The world first flexible full color 5.6‐inch active matrix organic light emitting diode (AMOLED) display with top emission mode on stainless steel foil is demonstrated. The active matrix back planes were fabricated using low temperature poly‐Si (LTPS). The p‐channel poly‐Si TFTs on the stainless steel foil exhibited the field‐effect mobility of 71.2 cm2/Vs, threshold voltage of −2.7 V, off current of 6.7× 1013 A/um, and subthreshold slope of 0.63 V/dec. These TFT performances made it possible to integrate scan driver circuit on the panel. A low‐cost planarization techniqe of stainless steel foil was developed to replace the expensive chemical mechanical planarization (CMP) method, which was the most critical barrier against mass production. The full color flexible AMOLED display on the stainless steel foil will be promising for mobile applications because of its thin, light, rugged, and design‐free properties.
