Samsung may be the sole supplier of LTOP OLED displays for the iPhone 13

Samsung will be the exclusive supplier of LTPO OLED displays for the “Pro” models in Apple’s iPhone 13 lineup expected in the September/October timeframe, according to TheElec.

Both models of the smartphone upgrade will purportedly use low-temperature polycrystalline oxide (LTPO) thin-film transistors (TFT) OLED panels made by Samsung Display. TheElec says that Apple’s iPhone 13 will have four models and all of them will use OLED panels. The top two models will use LTPO OLED that can support a 120Hz refresh rate.

A low-temperature polycrystalline oxide (LTPO) display is a special kind of backplane technology designed for OLED screens and developed by Apple. LG Display is planning to put in low-temperature polycrystalline oxide (LPTO) thin-film transistors (TFT) equipment that can add 25,000 substrates per month in monthly production rate into the lines by next year, according to The Elec.

LPTO tech allows a variable refresh rate of 120Hz for a smooth display and is able to optimize battery life. LTPO displays can already be seen on the Apple Watch Series 5 and Series 6. 

Such tech would help bring 120Hz ProMotion screens to the iPhone. According to Apple, ProMotion tech “delivers refresh rates of up to 120Hz for fluid scrolling, greater responsiveness and smoother motion content.”
