Redmi K70 Ultra’s C8+ screen to offer high-frequency PWM and DC dimming

The Redmi K60 Ultra was launched in August last year and the successor is also expected to launch this month. In the latest news, tipster Digital Chat Station claimed that the phone will support 3840Hz high-frequency PWM dimming below 60 nits brightness and DC dimming above that. According to the IEEE Std1789-2015 international standard, when the screen flicker frequency is greater than 3125Hz, the flicker reportedly poses no risk to the human eye. So the display can be considered eye-safe.

Reportedly, the display will use the C8+ luminous materials jointly developed by Xiaomi and Huaxing. The display is now more efficient and the longevity of the panel has achieved an “unimaginable breakthrough” of more than 100%. The Redmi K70 Ultra will be the first phone to launch with this new display panel. The high PWM frequency reduces eye fatigue and helps the panel to offer rich colors. The display panel will have a 1.5K resolution and will come with a flat design.

According to a recently revealed Geekbench listing, the phone equips the Dimensity 9300+ chipset, which offers a Cortex-X4 performance core that reaches up to 3.4GHz, 3X Cortex-X4 clocked at 2.85GHz, and 4X Cortex-A720 clocked at 2.0GHz. The chipset uses TSMC’s 3rd generation 4nm fabrication process and comes with an 18MB L3 + SLC cache. The phone will likely equip UFS 4.0 fast storage and could offer up to 24GB + 1TB configuration.

The phone will also equip on-device generative AI models such as “Tongyi Qianwen”, “Baichuan”, and “Wenxin Yiyan” and will reportedly offer a number of multimodal generative AI features. There will be a discrete graphics chip to provide super-resolution and super-frame functions for games.

The phone will come with an IP68 dust and water resistance rating just like the predecessor. To give you an idea of what to expect, the K60 Ultra equips the Dimensity 9200+ (4 nm) chipset and is available in the following configurations – 256GB 12GB RAM, 256GB 16GB RAM, 512GB 16GB RAM, 1TB 16GB RAM, 1TB 24GB RAM. It packs a 50MP main (1/1.49″, with OIS), an 8MP ultrawide, and a 2MP macro camera. There is a 20MP (1/2.0″, 0.8µm) selfie camera on the front.
