| titleOfInvention | Organic light-emitting diode display panel and manufacturing method therefor |
| abstract | A manufacturing method for an organic light-emitting diode display panel (100), comprising: providing a mother substrate (10) comprising a sub-substrate (110) and multiple removal areas (112) around the sub-substrate (110) which are defined by multiple cutting lines (12), the sub-substrate (110) comprising a display area (AA) and a non-display area (NA) surrounding the display area (AA); forming a pixel defining layer (130) on the display area (AA), the pixel defining layer (130) comprising an opening (132); forming an organic light-emitting diode (140) in the opening (132); forming a retaining wall (150, 152) surrounding the display area (AA); forming an anti-cracking structure (160) surrounding the retaining wall (150, 152); forming an encapsulation film layer (170) covering the pixel defining layer (130), the organic light-emitting diode (140) and the retaining wall (150, 152); and forming an organic protective film (180) which covers, from the side of the retaining wall (150, 152) away from the display area (AA), the multiple removal areas (112). Said method can reduce the risk that water and oxygen enter and corrode the organic light-emitting diode (140) caused by cracks generated when cutting the panel (100). The non-display area (NA) of the organic light-emitting diode display panel (100) has a better performance in releasing stress than a traditional panel. |
