The problematic AMOLEDs in Huawei's Mate 20 Pro are actually made by LGD, not BOE

Last week we reported that some Huawei Mate 20 Pro complain about a green tint in the smartphone's 6.39" 1440x3120 AMOLED display.

In our original post we reported that these displays are produced by BOE. However, according to Hernán Castañón (@hema), Huawei actually uses OLEDs produced by both LG Display and BOE - and all the faulty phones are one that use LGD made panels.

From what we understand, the problem is not the OLED panel itself, but its assembly and contacts. When LG Display launched its pOLED displays in 2017, the first batch of panels suffered from many issues but we hoped LGD's quality control improved since then. If this report is true, it seems that LGD's QA is still a challenge.
