  • Publication number: 20190355939
    Abstract: An ink drying process includes exhausting gas from atmosphere surrounding a substrate and drying ink through placing the substrate in a predefined pressure or less to form organic functional layers. Exhausting of gas includes: reducing, during a first period, pressure of the atmosphere from standard atmospheric pressure to a first pressure higher than vapor pressure of solvent having the highest vapor pressure among solvents of the ink; and subsequently reducing, during a second period, the pressure of the atmosphere to a second pressure lower than vapor pressure of solvent having the lowest vapor pressure among the solvents. Where pressure of the atmosphere is 10x Pa (X indicating a real number), a change amount average of X per unit time has a greater absolute value during the second period than during the first period.

  • Patent number: 9720448
    Abstract: A display unit which can realize reduction in thickness and weight of the display unit by omitting a void between a touch panel and a display panel, and its manufacturing method. Whole faces of the touch panel and the display panel are directly bonded together with an adhesive layer in between. The display panel has a structure wherein a driving substrate in which organic light emitting devices are formed and a sealing substrate are bonded together with an adhesive layer in between. The touch panel has a structure wherein a lower plastic film in which a transparent electrode is formed and a touch-side plastic film in which a transparent electrode is formed are layered so that the transparent electrodes are placed opposite. The display panel is constructed with only the driving substrate, and the organic light emitting devices are sealed by the touch panel instead of the sealing substrate. Therefore, thickness and weight of the display unit can be further reduced.
