Tech News 04 January 2020 According to the Korean website The Elec, some 2020 new iPhones will be equipped with a touch integrated display provided by LG:
LG Display plans to upgrade its production facility for flexible Gen-6 OLED panels for smaller displays at the E6 line in Paju, Gyeonggi-do. To this end, LG will add new equipment to produce touch integrated panels in early 2020, while turning to LTPO backplane technology. According to industry sources, because the E6 series is Apple’s exclusive product, the touch screen will be used on the 2020 new iPhone.
At the same time, according to the latest report from the Korean website ETNews, the Apple iPhone 12 Pro models will use a new technology that allows the touch screen circuit to be patterned directly on the OLED panel without the need for a separate layer, enabling thinner displays and reduce manufacturing cost. ETNews said that the lower-cost 6.1-inch model (presumably iPhone 12) will continue to use traditional displays.
It’s unclear whether this thinner display could change the thickness of the 2020 iPhone. It is worth noting that the iPhone 11 Pro and iPhone 11 Pro Max are actually slightly thicker and heavier than the iPhone XS and iPhone XS Max, respectively, because Apple uses a larger capacity battery in its latest iPhone.
The Elec’s latest report also indicates that LG intends to switch to LTPO back plane technology in the second half of 2020: the lower back plane of this technology is responsible for turning on and off individual pixels on the display. LTPO or low-temperature polycrystalline oxide has an oxide TFT structure, and its power consumption is reduced by 15% compared with Apple’s current backplane technology LTPS or low-temperature polysilicon. This will help improve the energy efficiency display of the 2020 iPhone and extend battery life.
Apple Watch Series 4 and Series 5 models already use LTPO displays. According to Apple’s official website, the technology allows the Series 5 to stay in the display state and has the same battery life as the Series 4 up to 18 hours:
Low-temperature polysilicon and oxide displays have a redesigned pixel architecture. When the watch is inactive, the screen refresh rate can be reduced from 60Hz to 1Hz power consumption. New low-power drivers, ultra-efficient power management and new ambient light sensors will work together, so the display can stay on and have up to 18 hours of battery life.
It’s unclear whether LG plans to use LTPO displays in bulk on the 2020 iPhone.
