In the last month of 2018, the full-screen form re-emerged, and the hole-cutting screen was born. First, after Samsung, it was Huawei. If it was completely unpredictable, it came to the next form.
Both Samsung and Huawei have screen openings in the upper left corner, but the technology is different. Samsung uses the through hole through hole solution, and Huawei uses the blind hole blind hole solution. The difference between the two is the size of the camera’s “hole”. Relatively speaking, Samsung’s opening is larger and Huawei is smaller.
