The invention discloses a display panel manufacturing method. The display panel comprises a display area, a hole area and a transition area located between the display area and the hole area. The display panel manufacturing method comprises the following steps: providing a display panel semi-finished product, the display panel semi-finished product comprising a substrate and a partition ring arranged on the surface of the substrate and located in the transition area, and the partition ring being arranged around the hole area; forming a desorption layer on the surface of the substrate and in the pore area, wherein the desorption layer is made of a material with the sublimation temperature being less than or equal to 200 DEG C; forming a light-emitting structure layer on one side, opposite to the substrate, of the desorption layer and located in the display area, the hole area and the transition area, wherein the part, located in the hole area, of the light-emitting structure layer is partitioned by a partition ring; and sublimating the material of the desorption layer so as to remove the part, located in the hole region, of the light-emitting structure layer.
Description
technical field [0001] The invention relates to the field of display technology, in particular to a method for manufacturing a display panel. Background technique [0002] With the rapid development of electronic devices, users have put forward higher requirements for screen-to-body ratio. Blind-hole screens that integrate front-facing cameras, earpieces, or infrared sensing elements under the screen have attracted the attention of display panel developers because they can achieve a higher screen-to-body ratio. [0003] However, due to the limitations of the existing hole-opening process, it is difficult to use a mask to shield the blind hole area during the evaporation process of the organic light-emitting film layer. Cut to remove the film layer in the blind hole area. However, it is difficult and costly to cut the organic light-emitting film layer in the blind hole area, which is not conducive to the commercialization and application of blind hole screens.
