What does the 2.5d screen of mobile phone mean?

2.5D screen is a kind of curved screen, also known as water drop screen, which is widely used in mobile phones, making the surface of mobile phones look like overflowing water drops, with more visual tension. 2.5D screen is not a screen glass material, but a glass named after its shape and technology.

The word "2.5D screen" belongs to a general term in the industry, which means that there is a flat area in the center of the glass and the periphery is curved, that is, the edge is curved on the basis of the flat glass.

Compared with the traditional 2D screen, the 2.5D screen is technically complex, so the cost is relatively increased. Because the glass polishing process will be too unsatisfactory in the processing process, the yield will be lost to some extent.

According to the manufacturing cost, a piece of 2.5D glass is about 3 to 4 times that of ordinary glass. Although the cost is not too high, it is generally only used for manufacturers' high-end flagship products.
