IPhone will use ltpo panel technology of Apple Watch

The elec, a South Korean website, said Apple plans to use a low-power panel technology called ltpo in future iPhones.

LTPO is the abbreviation of Low Temperature Polycrystalline Oxide (low temperature polycrystalline oxide. LTPO = LTPS Oxide, integrates LTPS and Oxide into the same pixel. Oxide is the bottom gate structure and LTPS is the top gate structure.

The new process, which combines the advantages of a strong LTP STFT process drive and low power consumption from the Oxde TFT process, has been used by Apple in the Apple Watch Series 5 model, and it is with this technology that Series 5 has a constant screen display and the same 18-hour battery life as Series 4.

From the point of view of process patent documents, LTPO needs to establish an oxide layer on the basis of LTPS. One of the most important problems last year was the need for manufacturers to ensure that the transistor characteristics in the original LTPS interlayer medium are not affected when laying the oxide layer. As Apple starts mass-producing the OLED screen with the LTPO and puts it on the Apple Watch, which has the largest share of smart watches, it proves that Apple has taken a big step forward in mass production of the LTPO.

It is well known that Apple's transition to OLED began with the initial Apple Watch, in 2015 and then extended to iPhone X in 2017, so the LTPO process did not stop at the OLED screen of Apple Watch Series 5, but the ultimate goal was the use of larger screens, such as iPhone,iPad, and even MacBook, which did not expect the process to take long.
