  • Patent number: 10243176
    Abstract: A method for repairing a bank during manufacture of an organic EL display device when a bank defect portion is produced due to collapsing of a bank, a foreign particle, or the like. The method includes: detecting a defect portion of a lengthwise bank formed over a ground substrate; and when a defect portion is detected, forming, in each of adjacent concave spaces between which the lengthwise bank having the defect portion is located, a dam partitioning the concave space into a first space in a vicinity of the bank defect portion and a second portion not in the vicinity of the bank defect portion. The shape of the dam is configured so that in ejecting organic functional layer ink in each concave space with a nozzle head, there is an ink dropping point in each of the first space and the second space.

  • Patent number: 9876060
    Abstract: A bank repair method in a manufacturing process of an organic EL display device including first and second banks forming a matrix over a substrate. When a defect portion of a first bank is detected, in each of adjacent concave spaces between which the first bank having the defect portion is located, a candidate forming position is set and a dam portion partitioning the concave space into a first space in a vicinity of the defect portion and a second space outside the vicinity of the defect portion is formed. When denoting sub-pixel region surface area as H and denoting a surface area of a region of a candidate first space overlapping with a sub-pixel region as I, the dam portion is formed at the candidate forming position according to a first forming method when I<?×H is fulfilled, where 0.05<?<0.9.

  • Patent number: 9837640
    Abstract: A bank repair method for repairing a defect portion of a bank in a process of manufacturing an organic electroluminescence (EL) display device including a substrate, banks formed over the substrate, and light-emitting layers formed in concave spaces defined by the banks. The bank repair method includes: examining whether or not a bank having a defect portion is present; and when a bank having a defect portion is present, repairing the bank by applying a repair material containing a gas adsorbent to the defect portion and curing the repair material; and after curing the repair material, baking the repair material by irradiating the repair material with infrared laser light.

  • Patent number: 9818809
    Abstract: An examination is performed of whether or not a bank having a defect portion is present. When a bank having a defect portion is present, the bank having the defect portion is repaired by forming a dam in each of adjacent concave spaces between which the bank having the defect portion is located. A dam formed in a concave space partitions the concave space into a first space in a vicinity of the defect portion and a second space outside the vicinity of the defect portion. The dam, at a portion thereof with lowest height, satisfies (h/H)+0.1W?1.5, 0.5?(h/H)?2.0, and 5?W?50, where a ratio of the height h of the dam to a height H of the banks is denoted as h/H, and a width of the dam is denoted as W ?m.
