Redmi K70 Ultra: C8+ Screen with High-Frequency PWM & DC Dimming

The Redmi K60 Ultra made its debut in August last year, and its successor is anticipated to launch this month. Recently, tipster Digital Chat Station revealed that the upcoming phone will feature 3840Hz high-frequency PWM dimming below 60 nits brightness and DC dimming above that level. According to the IEEE Std1789-2015 international standard, screen flicker frequencies above 3125Hz are considered safe for the human eye, making this display eye-friendly.

Advanced Display Technology

The display will incorporate C8+ luminous materials, co-developed by Xiaomi and Huaxing. This innovation enhances display efficiency and significantly extends the panel’s lifespan by over 100%. The Redmi K70 Ultra will be the first device to feature this advanced display panel, which reduces eye strain and delivers vibrant colors. The screen will have a 1.5K resolution and a flat design.

Powerful Performance

A recent Geekbench listing indicates that the phone will be powered by the Dimensity 9300+ chipset. This chipset includes a Cortex-X4 performance core clocked up to 3.4GHz, three Cortex-X4 cores at 2.85GHz, and four Cortex-A720 cores at 2.0GHz. It utilizes TSMC’s 3rd generation 4nm fabrication process and features an 18MB L3 + SLC cache. The device is expected to come with UFS 4.0 fast storage and could offer configurations up to 24GB of RAM and 1TB of storage.

Enhanced AI and Graphics

The phone will support on-device generative AI models such as “Tongyi Qianwen”, “Baichuan”, and “Wenxin Yiyan”, providing various multimodal generative AI capabilities. Additionally, it will include a discrete graphics chip for super-resolution and super-frame functionalities in gaming.

Robust Design and Specifications

The device will boast an IP68 rating for dust and water resistance, similar to its predecessor. For reference, the K60 Ultra is equipped with the Dimensity 9200+ (4 nm) chipset and offers configurations like 256GB with 12GB or 16GB RAM, 512GB with 16GB RAM, and 1TB with 16GB or 24GB RAM. It features a 50MP main camera with OIS, an 8MP ultrawide, a 2MP macro camera, and a 20MP front-facing camera.
