Patently Apple reports that the 8.5th generation organic EL (OLED) display panel under development by Samsung Display may be installed in the 2022 model iPad Pro.
Changed the vapor deposition method for organic materials
Samsung Display has received an order for 120 million OLED display panels for the 2022 iPad series, The Korea Times reported in July 2021.
According to Korean media The Elec, Samsung Display is working with ULVAC to switch to a vertical vapor deposition method in the manufacture of 8.5th generation IT OLED display panels.
In the 6th generation OLED display panel, the horizontal vapor deposition method in which the glass substrate is placed horizontally and the gaseous organic material is sprayed from the bottom to the top is the mainstream, but in this method, the central part of the metal mask is gravity. The Elec points out that there are weaknesses that are affected and hang down.
On the other hand, in the vertical thin-film deposition method, the glass substrate is placed upright and the organic material is sprayed in the horizontal direction for vapor deposition, so that the central part of the metal mask does not easily hang down. Stated.
Is the 2022 model iPad Pro installed?
Since the 8.5th generation OLED display panel is manufactured using a 2,200 mm x 2,500 mm substrate, it is expected to lead to a reduction in manufacturing costs compared to the 1,500 mm x 1,850 mm substrate used in the 6th generation OLED display panel. It has been.
Patently Apple predicts that this new OLED display panel could be included in the 2022 iPad Pro.
