Applying high dynamic range(HDR) to mini‐LED backlight is the current research interest of display. The partition control technology for backlight of mini LED is adopted to improve image contrast, however it can not avoid the introduction of halo, which affects the image quality and needs to be solved. Therefore, this article firstly proposes a method to evaluate halo; Then we studied the brightness distribution of the halo from the perspective of the backlight and the module. We also put forward some factors that affect the size of the halo. It is hoped that the design of backlight partitions can be guided through the study of halo.
