Who made the display on the Google Pixel 4 XL - Samsung or LG?
Earlier this week, Google launched its newest flagships, the Pixel 4 and Pixel 4 XL. Both devices joined the rather sparse list of devices to offer 90 Hz OLED displays. The Pixel 4 XL, in particular, has been hailed for its great display, but there hasn't been any official information on the company behind the phone's display.
There are three major display makers: Samsung Display, LG Display, and BOE. No Pixel phone has used a BOE panel, as the Chinese company usually sells hardware to its fellow sino-corps like Huawei. Both the Pixel 2 and Pixel 3 lineups used LG and Samsung displays, so that narrows down the list.
Google's official page doesn't say anything about what kind of panel it is—whether it's an LG P-OLED or a Samsung Super AMOLED. The official description simply reads, "QHD+ flexible OLED at 537 PPI". That doesn't tell us much we don't already know, sadly.
Thankfully, there are other means of finding out, and some research from before the launch of the phones have the display driver listed as the "dsi_s6e3hc2_cmd_display". That's a Samsung IC, which tells us what we need to know. The nature of displays makes it rather unlikely to get a panel and an IC from different manufacturers, so it's more likely that the panel was also made by Samsung.
In fact, that driver is apparently the same used on the OnePlus 7 Pro—a phone with a similar 90 Hz QHD+ AMOLED display that has been confirmed to be made by Samsung.
All of these point towards Samsung Display being the company behind the Pixel 4 XL's display. The smaller Pixel 4 is a different matter, though. The Pixel 2 and Pixel 3 phones had alternating displays—one by LG, and the other by Samsung. For example, the Pixel 3 had an LG display, while the 3 XL sported a Samsung one, and vice-versa for the Pixel 2 siblings.
As such wouldn't be surprising to find out that the Pixel 4 features an LG P-OLED, although there hasn't been a 90 Hz LG-made display on any smartphone until now. There's a first time for everything, though, right?
