Example Embodiment
[0029] In order to make the above objectives, features and advantages of the present invention more obvious and understandable, the present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments.
[0030] The inventor found that in order to punch holes in the display area, the cracks formed during the cutting process are related to the thickness of the inorganic layer of the cutting edge. In the process of depositing the film, CVD (Chemical Vapor Deposition) Mask and other masks cannot support and shield the perforated area. Therefore, the inorganic film deposited by CVD will extend from the effective display area to the hole. The cutting edge leads to an increase in the thickness of the inorganic film layer on the cutting edge, which causes cracks to be easily generated during the cutting process, and then the cracks extend to the effective display area in the subsequent process, resulting in package failure.
