Abstract
As consumers pursue higher display quality, Mini-LED backlight technology has become the focus of research in the current display field. With its size advantage (100–200 μm), it can achieve one-thousand-level divisional dimming, and it can also be combined with quantum dot technology to greatly improve the contrast, color gamut, dark state and other element of the display performance of LCD displays. Mini-LED backlight technology is undoubtedly the most ideal solution to realize a highly dynamic range display of LCD displays, and has been widely commercialized in many fields such as TVs, tablet computers, notebook computers, and car monitors. This review mainly introduces the efforts made by researchers to eliminate the halo effect, thinning of the backlight module and reducing the backlight power consumption. The application of quantum dot technology in backlight is also presented. We predict that the number of Mini-LED backlight partitions is expected to reach a level of more than 3000 in the future, further utilizing the advantages of the small size in local dimming, but it will also inevitably be challenged by some issues such as power consumption and heat dissipation.

Summary
Display technology is one of the most important means for us to express and obtain information. There are currently two major technology camps, organic light-emitting diode (OLED) display technology and liquid crystal display (LCD) technology [3]. Direct-lit backlight is still the most commonly used backlighting method for LCD It usually uses a sufficiently thick diffuser plate or leaves a large enough air gap between the backplane and the diffuser plate to convert the point light source into a uniform surface light source [13]. Both the diffuser and the air gap increase the thickness of the backlight module. The large increase in the number of Mini-LEDs can achieve uniform illumination and reduce the module thickness.
