Description

Technical Field

[0001] This utility model relates to the field of LED backlighting, and in particular to a low-power MiniLED backlighting control system. Background Technology

[0002] Traditional LED backlight systems generally suffer from problems such as high power consumption, difficult maintenance, and uneven light efficiency. In existing technologies, most LED strips adopt an integrated design, and once a single LED is damaged, the entire LED strip needs to be replaced, resulting in high maintenance costs.

[0003] In terms of optical design, conventional LED backlights mostly adopt a single-layer diffusion structure, which is prone to glare and uneven brightness, making it difficult to meet the requirements of high color gamut displays. These technical defects severely restrict the application effect and reliability of MiniLED backlight systems in the field of low-power displays. Utility Model Content

[0004] Therefore, it is necessary to provide a low-power MiniLED backlight control system to address the problems of high power consumption, difficult maintenance, and uneven light efficiency of traditional LED backlight systems.
