At the same time, it can retain the original delicate touch of glass. In order to better highlight the texture of the back cover and restore the charm of the summer sea, engineers adopted the "Snowflake AG Process". By developing a brand-new AG potion formula and controlling the crystal shape, the crystal of the back cover grows into snowflake shape, thus bringing more transparent reflective effect.
OPPO Find N uses a drop-shaped hinge:
This hinge design allows the screen to have a larger bending radius, thus reducing the crease problem. However, compared with the mainstream U-shaped hinge, the drop-shaped hinge has greatly improved both the cost and the number of parts. At the same time, more parts also put forward higher requirements for machining accuracy.
The hinge part of OPPO Find N has more than 400 key dimension control standards, and the highest accuracy reaches 0.01mm. In addition, in order to ensure that the screen is not affected by the hinge during opening and closing, OPPO repeatedly grinds the inside of the hinge to ensure the flatness is within 0. 15mm, and finally realizes multi-angle free hovering and the shallowest crease of the folding screen in the whole industry.
