RFMicro LED vs Mini LED: Key Differences Explained
Advertisement
This article explores the differences between Micro LED and Mini LED technologies, both recent advancements in the LED industry poised to impact smartphones, TVs, displays, laptops, and more. The primary distinction lies in their size, which leads to different applications and characteristics.
Mini LED
- Size: 100 to 200 µm
Mini LED displays utilize an LED backlight as the primary source of brightness. This light then passes through an LCD matrix and a set of color filters to create the image you see on the screen. Mini LED TVs, in particular, use thousands of these LEDs to power the backlight due to the significant reduction in LED size.
While more expensive than traditional LED backlights, Mini LED offers higher dynamic range and reduced power consumption.
Benefits of Mini LED:
- Easier mass production
- Higher yield rate
- Greater control over local dimming
- Better contrast
- Better brightness
- Better black levels
Micro LED
- Size: Less than 100 µm
Micro LED technology involves miniaturized LEDs arranged in a matrix. Each LED unit, smaller than 100 micrometers, is individually addressed and driven to emit light.
Micro LEDs utilize inorganic materials, such as Gallium Nitride (GaN), and are self-emitting, eliminating the need for a backlight.
Benefits of Micro LED:
- High luminous efficiency
- Thinner
- Lighter
- Less power consumption
- Wider viewing angle
- Long life
- Shorter response time
- Higher resolution

The following table summarizes the key differences between Micro LED and Mini LED technologies:
| Specifications | Mini LED | Micro LED |
|---|---|---|
| Size | 100 to 200 µm | Less than 100 µm |
| Yield Rate | Higher | Lower |
| Mass Production | Less difficult | Difficult |
| Cost | Less | High |
| Lifetime | Medium | Long |
| Response time | In microseconds | In nanoseconds |
| Energy consumption | Medium | Low |
| Viewing angle | Medium | High |
| Number of LEDs (TV) | More than thousand (direct lit) | Millions |
| Luminous efficiency | Medium | High |
| Applications | LCD backlight, fine pitch display wall | Self emitting display wall, Micro-projection display wall |
