Visionox innovatively develops LTPO partitioned multi-frequency technology to achieve line-by-line adaptive refresh rate

In recent years, with the advancement of screen technology, users have made new breakthroughs in visual experience, but this has also brought about issues with mobile phone power consumption and battery life. In order to solve this problem, LTPO adaptive refresh rate technology came into being, aiming to balance visual experience and power consumption

Visionox announced today that the company has successfully developed LTPO partitioned multi-frequency technology. And produce technical samples. Through independent research and development of GIP circuits, this technology can achieve arbitrary partitioning with "rows" as the smallest unit. It can flexibly set the number, location and size of partitions in horizontal partitions, thereby realizing new functions of multiple refresh rates for partitions.

Visionox claims that partitioned multi-frequency technology is the first to be upgraded at the hardware level. Through the innovative design of the screen body, it can achieve a more precise adaptation of display content and refresh rate, which can make the IC power consumption the highest. Reduced by 10.95% (Note from this site: Data calculated under second partition).

▲ Two-partition multi-frequency

▲ Three-partition Multi-frequency

▲ Four-partition multi-frequency

Specific to the usage scenario, current conventional folding mobile phones, tablets and other devices have split screens When using the app, for example, watching a video on the left, scrolling through Weibo or documents in the upper half on the right, and a video in the lower half, the device will default to a full-screen unified refresh rate.

Visionox's partitioned multi-frequency technology is installed in smart phone terminals. According to differences in local display requirements, each partition can adapt to a different refresh rate in units of "rows" . For example, when displaying low frame rate content such as static images, text, and clocks, the refresh rate is matched to a low refresh rate, and the refresh rate is matched to a high refresh rate for video and information stream content, thereby achieving precise control of the refresh rate and reducing power consumption.
