摘要： A manufacturing method of a multilayered board, includes: a dot pattern forming process that forms a dot pattern comprising at least one hemispherical micro-lens shape by repeating a process of forming one hemispherical micro-lens shape by jetting one droplet for forming the dot pattern in an inkjet manner; and a stack pattern forming process that forms a stack pattern having a thickness less than that of the micro-lens by jetting a droplet for forming the stack pattern on a predetermined area around the dot pattern in the inkjet manner.

摘要： An inkjet printing method may includes a dot pattern printing process of printing a dot pattern group by discharging ink at a preset position of a surface of an object using a nozzle group for forming a dot pattern so that dropped droplets are not in overlap with each other, a connection pattern printing process of printing a connection pattern group by discharging ink at a position between neighboring patterns using a nozzle group for forming a connection pattern so that the same attractive force acts to the neighboring patterns dropped on the surface of the object, and a finishing printing process of finishing a coating of the surface of the object by discharging ink to an area except for neighboring dropped droplets using a nozzle group for finishing so that the same attractive force act to the dropped droplets that are dropped on the surface of the object.

摘要： A display apparatus according to an embodiment has improved resolution by realizing a pixel as a rectangular structure to perform four-times greater high resolution pixel printing within a limit of an accuracy and a size of a currently existing ink drop. A display apparatus includes a first light emitting group including four first sub-pixels contained in different pixels to emit the same color light, a second light emitting group including four second sub-pixels contained in different pixels to emit the same color light, a third light emitting group including four third sub-pixels contained in different pixels to emit the same color light, and a fourth light emitting group including four fourth sub-pixels contained in different pixels to emit the same color light, and four of the first sub-pixel, the second sub-pixel, the third sub-pixel, and the fourth sub-pixel, which are disposed closest to each other, form one pixel.
