When Google officially launched the Pixel 4a, a lot of you may have been surprised at how the company incorporated an OLED panel on the mid-range beast while also stamping an affordable $349 price tag on it? The answer lies in the little details, with a display analyst commenting that it was the kind of OLED Google decided to use on its latest offering that helped maintain such a low price.

Fresh insight from DSCC analyst Ross Young claims that instead of a flexible OLED panel, Google decided to employ the use of a rigid OLED for the Pixel 4a. The result? Massive production cost cuts to the point where each rigid OLED costs one-third the price of its flexible counterpart. Additionally, procuring a massive shipment of these OLED screens means that the manufacturer or manufacturers would have likely given Google an attractive discount.
