Analysis of the difference between Mini LED & Micro LED

Mini LED and Micro LED are regarded as a new generation of display technology, and their market prospects are highly promising. Since the concepts of Mini LED and Micro LED are so hot, what are they? What is the difference between the two? Today we analyze the two from the perspectives of R&D progress and industry applications.

1. Definition
Definition of Mini LED: Mini LED is also called "sub-millimeter light-emitting diode". It adopts 100-200 micron LED crystal and is an improved version of traditional LED backlight. Mini LED technology is considered as a transitional technology between traditional LED and Micro LED. Using Mini LED can produce display screens with 0.5-1.2 mm pixel particles, and the display effect is much better than traditional LED screens.

Micro LED definition: Micro LED is LED miniaturization and matrix technology. In simple terms, it is to thin, miniaturize, and array the LED backlight so that the LED unit can be smaller than 100 microns, and it can realize each image like OLED. The unit is individually addressed and driven to emit light separately (self-luminous).

2. Development prospects

Mini LED development prospects:
Mini LEDs are mainly used in fields such as display screens, automotive displays, mobile phones and wearable devices. Starting in mid-2018, the application side of Pad, car, e-sports, and TV (especially TV) have shown a strong interest in Mini LED, which will be used as an alternative to OLED. Driven by market demand, the production and research and development of Mini LEDs are being accelerated.

Micro LED development prospects:
As a new generation of display products, Micro LED will mainly be applied in the existing markets of LCD and OLED in the future. Application directions include smart watches, smart phones, tablets, automotive instruments and central controls, and TVs (including large-size TVs and super-size TVs). From a market perspective, Micro LED is more suitable for indoor large-size displays and small-size wearable devices, such as smart watches, in the short term.

Three, research and development progress analysis
At present, the development of Mini LED is more mature, and the technical difficulties of Micro LED need to be broken through.
