为了实现低温工艺形成阴极层，避免损坏发光材料层，本申请也提供了多种实现方式。
现有支持挡墙PS柱是截面为正梯形高度为1.5um的高圆柱状支撑柱，起到了的支撑蒸镀用掩模板Masks的作用，然后会在上面覆盖有一整面的阴极层。本申请将PS柱的高度相对提高，这样按照原有工艺沉积的Cathode材料，将不再能完整覆盖整个膜层，露出由于较高PS柱使得cathode分隔开形成间隙，使得Cathode图案化方案得以实现。

在一种实施例中，所述支撑挡墙62的截面为倒等腰梯形。
本实施例将PS柱做成高度较高，截面为倒等腰梯形的圆柱状支撑柱，由于其高度较高，上宽下窄的形状，使得其更能分隔开Cathode材料，实现Cathode的图案化的效果最好，相邻同类Sensor pads间（不同行或列的Tx / Rx）以及相邻不同类Sensor pads之间（如相邻Tx和Rx之间）被PS柱隔开，实现Cathode图案化。
现有制作Cathode层的方法是利用Common Metal Mask（CMM），在发光材料EL层上方沉积制作整面的Cathode，而OLED器件的RGB像素材料则是利用Fine Metal Mask（FMM）制作。因此在图案化Cathode时，本申请直接利用FMM实现其图案化，可以确保其精度满足显示区高PPI设计。

在一种实施例中，在本申请的显示装置中，所述触控功能层与所述阴极层为同一层，所述第一区域内的阴极层形成第一触控电极，所述第二区域的阴极层形成第二触控电极。
在一种实施例中，在本申请的显示装置中，所述第一触控电极为驱动电极，所述第二触控电极为感应电极；或者，所述第一触控电极为感应电极，所述第二触控电极为驱动电极。
