Description

一种主动阵列有机发光二极管显示模块 技术领域
本揭示涉及主动阵列有机发光二极管(Active-Matrix Organic Light-Emitting Diode，AMOLED)显示技术领域，尤其是涉及一种均匀阴极电压的AMOLED显示模块。
 背景技术
AMOLED显示技术相对于液晶显示（Liquid Crystal Display，LCD）技术具有自发光、广视角、高亮度、高发光效率、低厚度、高画面对比度、反应速度快等优点，AMOLED显示技术已广泛应用在各种电子显示设备上，以提升产品的效能与消费者感受。如图1、图2所示，在现有AMOLED显示面板600的结构中，在间绝缘层（Interlayer Dielectric，ILD）608上形成第一金属导电层610、公共接地(VSS)部602，在第一金属导电层610与公共接地部602上形成绝缘的平坦化层(Planarization Layer、PLN)612，在平坦化层612中的通孔设置阳极604，并在平坦化层612上形成与公共接地部602电连接的金属连接部616，在阳极604上形成像素界定层(Pixel Define Layer，PDL)614，像素界定层614并覆盖部份的金属连接层616，在像素界定层614所形成的预定位置内设置OLED组件618，接着在像素界定层614上与OLED组件618对应的位置形成第二金属导电层620，在第二金属导电层620上形成整面的阴极606结构，阴极606并延伸至与金属连接部616电连接的位置，因此阴极606可通过金属连接部616与公共接地部602电连接。
每个OLED组件618的两端电极是通过下层阵列（Array）结构提供阳极604电压和OLED组件618上部的阴极606公共接地电压（VSS）形成电压差，使电流从阵列结构的阳极604通过OLED组件618流向阴极606，从而激发OLED组件618发光。图1中的AMOLED显示面板600中的阴极606为一块整面性的镁铝合金薄膜，阴极606的VSS电压信号从阵列结构边缘的金属连接部616引出，因此导致阴极606的VSS电压信号在AMOLED显示面板600的中间部位与边缘部位的电压均匀性比较差，从而影响AMOLED显示装置显示效果的均一性。
因此，需要提出一种新的AMOLED显示技术以改进阴极电压信号的均匀性和显示效果的均一性，并解决现有技术的缺陷。
