Towards the end of 2021, it was reported that Visionox has finalized its LTPO R&D project and is ready to start producing LTPO OLED displays. The company now officially launched its first LTPO AMOLED dipslay, that can offer a dynamic refresh rate, from 1Hz to 120Hz. Visionox expects the first phones to adopt these new displays to be released soon.
The new LTPO AMOLED displays are produced at Visionox's Hefei 6-Gen flexible AMOLED line. This is the first LTPO OLED displays produced in China (previously only Samsung and LG produced such advanced panels).
Low-Temperature Polycrystalline Oxide, or LTPO, is an OLED display backplane technology developed by Apple. LTPO combines both LTPS TFTs and Oxide TFTs (IGZO, Indium Gallium Zinc Oxide) to enable variable refresh rate displays, and power savings of up to 15%. LTPO AMOLED displays are widely used today in high-end smartphones and other mobile devices.
