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.
- 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.
