Smartphone manufacturers are striving today to reduce the bezels on their phones in order to make displays bigger. To that effect, Apple is all set to use LED backlighting chips along with its LCD panel to reduce the bezels on its upcoming 6.1-inch iPhone so that it looks identical to its bezel-less OLED screen.
According to DigiTimes, Apple will be using the services of Japanese company Nichia exclusively for sourcing the LED backlighting chips for its iPhone with LCD display. Here’s an extract from the report.
While LTPS-LCD smartphone screens with backlights using 0.4t LED chips have bottom bezels of 4.0-4.5mm, use of 0.3t LED chips can reduce them to 2.0-2.5mm, enhancing LCD screens’ competitiveness against OLED all (bezel-free) screens panels, the sources explained.
Packaging of 0.3t LED chips for side-view backlighting of LTPS-LCD smartphone panels is more difficult in accuracy and stability than that of 0.4t LED chips, the sources noted, adding Nichia began trial production of 0.3t LED chips for use in high-end smartphone models launched by China- and Japan-based vendors in the first half of 2018.
Apple is widely expected to launch three new iPhones this year in September, one of which will feature an LCD display while the other will have OLED displays. This attempt from Apple must be to achieve a uniform look for all its iPhones irregardless of the display technology used.

According to Apple analyst Ming-Chi Kuo, the LCD iPhone will have a lower cost than its OLED siblings, and will probably be priced close to what the iPhone 8 and iPhone 8 Plus was, which is $700-$800.
