A previous and ‘final’ specs leak revealed that both the Pixel 6 and Pixel 6 Pro would ship with OLED screens, which should not be surprising because Google used the same display on the affordable Pixel 4a. However, you should know that there is not just a single type of OLED, and an analyst believes that Samsung will supply rigid versions of this panel to reduce production costs for Google. This can also mean the Pixel 6 will be priced competitively.

While the display type is not yet known for the ‘Pro’ model, Ross Young comments that using a rigid OLED will help save Google a ton of costs. Even before, Young explained that Google was able to use an OLED screen for the Pixel 4a and still price it at $349 because it was not a flexible panel.
