TCL CSOT demonstrates a notebook display capable of an ultra-low refresh rate of 0.01 Hz. This is achieved using a high-mobility oxide backplane technology, which allows for very fast electron movement and enables new display driving designs. The technology is presented as ready for mass production, with potential market availability as early as next year depending on demand.

HDMI® Technology is the foundation for the worldwide ecosystem of HDMI-connected devices; integrated with displays, set-top boxes, laptops, audio video receivers and other product types. Because of this global usage, manufacturers, resellers, integrators and consumers must be assured that their HDMI® products work seamlessly together and deliver the best possible performance by sourcing products from licensed HDMI Adopters or authorized resellers. For HDMI Cables, consumers can look for the official HDMI® Cable Certification Labels on packaging. Innovation continues with the latest HDMI 2.2 Specification that supports higher 96Gbps bandwidth and next-gen HDMI Fixed Rate Link technology to provide optimal audio and video for a wide range of device applications. Higher resolutions and refresh rates are supported, including up to 12K@120 and 16K@60. Additionally, more high-quality options are supported, including uncompressed full chroma formats such as 8K@60/4:4:4 and 4K@240/4:4:4 at 10-bit and 12-bit color.

The key feature of this display is its ability to dynamically and automatically adjust the refresh rate in different regions of the screen. An AI-based auto-detection system identifies static and dynamic content. For example, a video playing in a window can run at a high frequency of 120 Hz, while the rest of the static screen area, such as text or a still image, drops to 0.01 Hz. This switching is instantaneous and automatic.
This variable refresh rate capability leads to significant power savings. The amount of power saved depends on the proportion of the screen operating at the low frequency. The demonstration suggests a power consumption reduction of around 20% when a high-frequency video window is active. For use cases like reading static text across the full screen, the power savings would be substantially greater, potentially extending a notebook’s battery life by several hours.
By reducing power consumption, the technology aims to extend device usage time. The on-screen information suggests that for video playback, this could result in one extra hour of battery life. For static content consumption, the gains would be even more significant, directly addressing a major challenge for portable computing devices.
