Delivers high performance touch sensing with variable refresh rates and optimal battery life.

Synaptics Incorporated announced that its Rio family of OLED touch controllers is being used to support LTPO-enabled OLED displays in new flagship mobile phones from Oppo and One Plus.

LTPO displays improve power efficiency by adapting their refresh rate to the content being played while also being sensitive to interference from touch controllers that do not properly support constantly shifting refresh rates. The Synaptics Rio family dynamically adapts to the LTPO panel refresh rate, enabling a smooth touch experience without interfering with the display performance.

The Synaptics Rio touch controller enables a best-in-class touch experience on LTPO display in the Oppo Find X3/X3Pro and OnePlus 9/9Pro devices.

Low temperature polycrystalline oxide (LTPO) thin film transistor technology is increasing in popularity as it allows the OLED display to dynamically lower its refresh rate depending on the use case, which results in higher power efficiency. Rio controllers adapt to different display refresh rates from 1-120 Hz while maintaining optimum touch performance and avoiding any interference with LTPO displays.
