Mini LED vs Micro LED vs OLED: What's the Difference?


This article introduces the technology of Mni LED, Micro LED and OLED, and what's the difference between them.

What is Mini LED?​

Mini LED backlight technology is an LED technology with a new backlight design. It thins, miniaturizes and arrays the LED backlight, so that the LED unit is only about 1mm*1mm, and the effect of delicate light control is realized. Compared with traditional LCD screens, MiniLED has many obvious advantages such as high contrast ratio, high brightness and ultra-thinness. That is to say, under the same size screen, the screen displayed by the MiniLED technology is more delicate and the color reproduction is higher.

What is Micro LED?​

Micro LED refers to Micro Light-Emitting Diode, which is smaller in size than Mini LED. Micro LED also does not require backlight modules and optical color filters. It uses inorganic materials to form the light-emitting layer, so it is not prone to the common screen burn-in problem on OLEDs. At the same time, the screen transmittance is better than LCD and OLED, and it is more power-saving.

Micro LED is to weld micro light-emitting diodes to a TFT substrate. The volume of each Micro LED is less than 30 nanometers, which is equivalent to 2.07 million pixels in a 1080p screen, and 8.29 million pixels in a 4K screen.

It is characterized by high brightness, high contrast, high definition, strong reliability, fast response time, more energy saving, and lower power consumption than LCD and OLED. The same self-luminous display technology is used, but the brightness of Micro LED is 30% higher than that of OLED, which is suitable for automotive, industrial and military fields.

What is OLED?​

OLED refers to Organic Light-Emitting Diode, abbreviated OLED, its main feature is that it can emit light and color independently without backlight modules and color filters.

Compared with LCD, OLED has a simpler structure and higher cost. Apple used OLED for the first time on the iPhone X in 2017, and until 2020, the entire iPhone 12 will use OLED screens.

The advantages of OLED are: self-illumination, no need for components such as backlight modules; thinner and more power-efficient; bendable; wider color gamut, higher brightness, ultra-high contrast, more vivid colors; and low latency.

Its disadvantages are also obvious. The biggest impact is the problem of burn-in and color shift, which is also a common display problem for all OLED screen devices.



Mini LED panel features:

  • Lightweight and power saving
  • Brightness and contrast surpass HDR
  • Wider color gamut and more saturated colors
  • Peak brightness increased by 3~5 times (>1000nit)
  • Display life is 3~5 times longer than OLED
  • Up to 80% power savings compared to OLED
  • Lower cost than OLED
