R15 is announced in 5 colors, including Snow White, Heat Red, Starry Purple, Dream Mirror Red, and Ceramic Black. The back covers of the first 3 colors are made of 2.5D glass. The Dreamland Red uses 3D glass with a larger curvature, while the Ceramic Black is further upgraded to a 4-curved surface material.
Since the curvature of the 2.5D edge and the 3D edge are obviously different, the middle frames of the R15 are also made differently according to the colors of the R15. The dream red of the 3D glass and the ceramic black of the 4-curved ceramic The middle frame will be thinner.
Extended information:
1. Sectional manufacturing process
Ceramic black ceramic version: 3D four-curved surface design, made of high-purity nanoscale zirconia powder. 72 hours of high-temperature firing at 1480°C, 50 minutes of CNC precision machining, 370 minutes of double-sided grinding and polishing, and a total of 19 processes to create. It has high hardness, wear resistance and corrosion resistance. Compared with metal, it is also more advantageous in mobile phone signal transmission. .
2. Design concept:
Purple is a combination of red and blue, representing the collision of passion and calmness. At the same time, purple is often the color of the starry sky, which gradually changes from black to purple, just like the starry sky derived from the night, with endless mystery and depth. Karim Rashid expressed that he hopes to express the infinite possibilities of R15 and its connectivity in the digital age.
Gradient red is similar to vermilion, like a color created by combining deep red with happy yellow, conveying emotions such as energy, passion, love, and happiness. Karim Rashid successfully applied it to the OPPO R15 Dream Mirror Edition, full of enthusiasm and vitality. Other versions of OPPO R15, such as Snow White and Heat Red, all contain Karim Rashid’s unique color concept.
3. Media evaluation
As early as January 2017, OPPO applied for a patent for a display screen on the patent website, with a portion of the screen left in the middle, similar to the iPhone X's notch screen, but it's a few months earlier than the iPhone X. In terms of industry trends, the second half of 2018 will see a large number of full-screen mobile phones with notch designs. It would not be surprising if OPPO R15 is as exposed as the picture.
