In May, The Elec said that both Samsung and LG are hesitant on the spending plan on Gen 8 OLED as it is yet “undecided how much Apple will pay” for it. But while the manufacturer expects to earn big money with this transition, a continuous decline in MacBook revenue could put this upgrade at risk.

This move to OLED will improve the speed and contrast ratio. That said, Omdia’s revised forecast says the panels must be mass-produced in 2026 so Apple can release OLED MacBook Pro by 2027. LTPS TFT technology must be developed before LTPO TFT can be applied,” explains the publication. LTPO TFT technology is being mass-produced in the existing 6th generation OLED line, but low-temperature polycrystalline silicon (LTPS) TFT technology for the 8th generation OLED line has not yet been developed. “In order to produce OLED MacBook panels in the 8th generation OLED lines for IT of panel makers such as Samsung Display, it is necessary to respond with oxide TFTs.
