Last month Huawei started shipping its second-generation foldable smartphone, the Mate X2, and the first review, from Android Authority is in. And the reviewer really likes the device - saying it may even be better than Samsung's own foldable smartphones.

The inner-folding 8-inch 90Hz 2480 x 2200 AMOLED is said to be beautiful, and it is completely flat when open - with a really minimal bezel that can barely be seen. According to the reviewer, that's a huge improvement over all other foldables they used. The phones feels very solid, in fact, and the hinge seems much more durable than before.

Huawei says that the foldable screens adopts a "magnetically-controlled nano optical layer" to reduce reflection and glare (the company says reflectivity is <1.5%, compared to >5% in the Galaxy Fold 2). The cover is plastic (and not UTG like in Samsung's latest displays).

Glass and plastic for flexible display

I am wondering if, in theory, it would be possible to use mostly a glass cover for the internal flexible displays that they feel at touch like regular smartphone displays in the way below :

1. use 2 separate glass sheets on right side and left side of the flexible display

2. in the middle use flexible plastic (to get the flexibility) to join the right side and left side glass sheets. One of the big challenge is that it must however be optically seemless in a way to join the 2 glass sheets in a way that it give the feeling of one uniform glass sheet.

I understand that it would likely be extremely challenging to realise due to the materials different refractive index, but with smart and hard engineering work, I am wondering if it could be realise to get a better touch feeling in regards of the internal flexible display
