OnePlus 5 Focus on Dual-Lens Camera

Dan Seifert:

Even with the advantage of being based in Shenzhen, OnePlus still can’t always get the best components other companies might have. After all, both Apple and Samsung make their own processors, and Samsung is one of the leading manufacturers of display technologies in the world. Those in-house display and chip technologies show up in their phones long before they make it anywhere else. (Or in the case of Apple’s chips, they never show up in other companies’ products at all.)

For the OnePlus 5, that meant the company wasn’t able to utilize the tall, edge-to-edge screens that Samsung and LG have pushed this year. “This is something we want to try,” says Lau. “But we don’t currently have the resources or access to those displays.”

So OnePlus zeroed in its efforts on the part it can get: a better camera. The OnePlus 5 features a dual-camera system, a first for the company.

The “tall, edge-to-edge screens that Samsung and LG have pushed this year” are not merely tall and edge-to-edge; it is not just a different form factor. Those screens are the best screens that have been integrated into smartphones; they are even better than some of the best TV screens. These two companies’ smartphone displays are at the top or very near the top in color gamut, color accuracy, contrast, reflectance, brightness, and a plethora of other display metrics. Samsung has OLED, and LG has IPS LCD; Samsung’s OLED is curved, and LG’s IPS LCD is not. Either way you can’t go wrong with their tall, edge-to-edge screens, but the truth is as Seifert wrote: it will be a while before these beautiful displays get into the hands of other brands. The one exception would be Apple with its next iPhone expected to be announced around September with OLED displays that will likely be supplied by both Samsung and LG.

I expect the OnePLus 5 to have a good implementation of a dual-lens camera, especially the camera’s portrait capabilities. Similar in design and in function to the dual-lens iPhone 7 Plus. But the focus on making a better camera is not good enough. The challenge is to make the display as good as the camera. The display has to be just as good at transforming electrons back into photons as the camera is at transforming photons into electrons. For smartphone photography a great display with a so-so camera is just as useless as a so-so display with a great camera. The two go hand in hand. This camera-and-screen one-two punch is one of the many reasons why the Samsung Galaxy S8, LG G6, and the iPhone 7 Plus are considered to be the best smartphones on the market today. The OnePlus 5 launches tomorrow at noon in New York City.

Japan Display Inc. Full Active Flex Bendable LCD

Japan Display Inc. Full Active Flex Bendable LCD

Japan Display Inc. or JDI is one of the few display manufacturers who supply smartphone displays to Apple. JDI also has the world’s largest production capacity of LTPS (Low Temperature Poly-Silicon) LCDs, an important fact considering LTPS is required if multitouch performance is important.

JDI announced a 5.5-inch LCD that’s bendable. JDI is calling the technology FULL ACTIVE FLEX. Bendable displays have up until now been limited to OLED technology. OLED is still more bendable than JDI’s bendable LCD, but JDI’s LCD bends enough that it could work as the curved display in the Samsung Galaxy S7 Edge. Bendable LCDs have the potential to be considerably more affordable than OLED because of the vast manufacturing infrastructure; the LCD industry will need to transition from glass substrates to plastic substrates for that to happen though.

Technical Specifications:

  • Display: 5.5-inch IPS-NEO LCD with Plastic Substrates
  • Pixel Format: 1920×1080 RGB
  • Resolution: 401 ppi
  • Driving Frequency: 60Hz, 30Hz, 15Hz
  • Brightness: 500 cd/m2 (typical)
  • Contrast Ratio: 1500:1 (typical)

LCD is liquid crystals sandwiched by two glass substrates. Although Corning has come out with bendable glass (Willow Glass), JDI replaced glass with plastic. Plastic bends, of course, but it is also more resistant to cracking and shattering than glass.

Apple, Samsung, and others who make smartphones use an extra layer of cover glass to protect the display underneath. The use of a cover glass like Corning’s Gorilla Glass protects the display and at times can add to a more seamless design, but it makes the smartphone thicker and more expensive. I like the idea of durable, bendable plastic LCDs not needing an extra layer of protection.

JDI plans to enter mass manufacturing in 2018.
