It contains a white tray that has four assembled display/digitizer components.
The images, which should be treated with skepticism, claim to show the iPhone X Plus screen and digitizer at an LG facility in Vietnam.
The first photo shows us a digitizer part held in a person's hand. As can be seen in the image provided below, the width of the notch relative to the digitizer seems different than the one on the iPhone X.
A report by KGI Securities analyst Ming-Chi Kuo, Apple is expected to discontinue the iPhone X later this year when the company introduces their 2018 iPhone line rather than following the tradition of continuing to sell older devices for a reduced price. Nonetheless, it's unclear if the depiction points to the claimed rumors.
Commenters in the MacX forums say they match up with format used by Apple for previous parts.
Samsung was the sole supplier of OLED displays for the iPhone X but a recent news shows that LG could become the supplier for the iPhone X Plus. There's also a production week, the 46th week of 2017, listed on the flex cable. There aren't too many additional details to extract from this, although the earpiece slot and sensors can be recognized along the top.
It's previously been rumoured that Apple will release three new iPhone models later this year, all with edge-to-edge displays: a new version of the iPhone X, an iPhone X Plus and another iPhone model but with an LCD display instead.
