In recent years, with the high refresh rate, high resolution and other screen technology development, the user experience has also stepped up to a new level. At the same time, it also brings the problem of power consumption and battery life of the cell phone. In order to pursue a balance between visual experience and power consumption, LTPO Adaptive Refresh Rate technology has emerged.
Visionox today announced that the company has successfully developed LTPO partitioned multi-frequency technology and produced samples of the technology. This technology, through self-developed GIP circuits, is capable of realizing arbitrary partitioning with “row” as the smallest unit, and flexible settings of the number, position and size of partitions can be realized in horizontal partitioning, thus realizing the new function of multiple refresh rates in sub-areas.
Visionox said that the partition multi-frequency technology is the first to upgrade at the hardware level, through the innovative design of the screen body, to achieve a more accurate adaptation of the display content and refresh rate, which can reduce the IC power consumption by a maximum of 10.95% (measured data under the two-partitioned area).

Specific to the use of the scene, the current conventional folding cell phone, tablet and other devices split-screen use of the App, such as the left side of the video, the right side of the brush microblogging, or the upper half of the document, the lower half of the video of the scene under the device will be the default full-screen uniform refresh rate.
Visionox’s multi-frequency partition technology is equipped on smartphone terminals, which can adapt each partition to a different refresh rate according to the differences in local display needs, in terms of “rows” as a unit. For example, when displaying low frame rate content such as static images, text, clocks, etc., it matches low brush, and for video and information streaming content, it matches high brush, so as to achieve precise control of the refresh rate and realize the purpose of reducing power consumption.
