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，如图6所示，显示面板包括像素定义层S61，所述像素定义层S61之上设置有支撑挡墙62，所述支撑挡墙62的高度大于所述阴极层S62的厚度，将所述阴极层S62分割以形成所述第一间隙。
在一种实施例中，如图6中（1）所示，所述支撑挡墙62的截面为三角形。
在一种实施例中，支撑挡墙62的截面为等腰三角形。

在一种实施例中，如图6中（2）所示，所述支撑挡墙62的截面为梯形。
在一种实施例中，所述支撑挡墙62的截面为等腰梯形。
本实施例将PS柱做成高度较高，截面为等腰正梯形的圆柱状支撑柱，由于高度较高，在Cathode沉积工艺不变的情况下，能分隔开Cathode材料，实现Cathode的图案化。
在一种实施例中，如图6中（3）所示，所述支撑挡墙62的截面为倒梯形。
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，如图7所示，所述阴极层包括交错设置的第一区域S71以及第二区域S72，所述第一区域与第二区域之间形成所述第一间隙73，所述第一区域内的阴极层与第二区域的阴极层通过多道工艺形成。
如图7中（1）所示，首先使用第一层FMM，选择性沉积形成第一区域S71，作为驱动电极Tx电极74，并使其连接Tx行/列连线75；
如图7中（2）所示，然后使用第二层FMM，选择性沉积形成第二区域S72，作为Rx电极76，使其与Tx和Tx line隔离；
最后沉积一层TFE封装整个Cathode层；
整个过程无需photo和Etch参与，可以避免photo和Etch损伤下方的OLED发光器件。
在一种实施例中，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，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。
在一种实施例中，本申请采用低温材料和制程，使用光阻和低温PR胶，使用传统过程刻蚀，在过程中增加钝化层和保护层，避免刻蚀过刻，伤害OLED发光器件，从而实现Cathode图案化。在本实施例中，所述显示面板包括依次设置于所述阴极层之上的钝化层和保护层，所述第一间隙为对所述钝化层、保护层以及阴极层在一道工艺中蚀刻形成的。
在一种实施例中，本申请沉积整面Cathode之前，涂布图案化的剥离胶，沉积Cathode后，撕去剥离胶，实现Cathode的图案化。在本实施例中，所述第一间隙为设置于所述阴极层之下的剥离层，剥离形成的。
