Document Type and Number:
WIPO Patent Application WO/2021/169013
Kind Code:
A1
Abstract:
Disclosed are a structure and method for optimizing an ink-jet printing encapsulation process, and a display screen. The structure comprises a first dam portion (1) arranged along the periphery of an effective display area, the first dam portion (1) comprises a plurality of first shielding portions (11) connected in sequence, and a plurality of drainage portions (12) used for guiding ink and arranged in the vertical direction are arranged on the inner side walls of the first shielding portions (11), and a first gap allowing the ink to flow through is provided between adjacent drainage portions (12). The method comprises the step of guiding, by means of drainage portions (12), ink to be added to an ink filling area. The display screen comprises the structure for optimizing the ink-jet printing encapsulation process. The dam portion structure is improved in the design of a display screen frame, and the ink is accurately guided to the ink filling area under the action of the drainage portions, such that the probability that the ink crosses the dam portion is reduced, the probability of overflowing occurring is reduced, and the cost is thus reduced.
