What is a MicroLED

38.

What is a MicroLED Display?
• Also known as micro-LED,
mLED or µLED.
• MicroLED displays comprise
several microscopic LEDs,
which self-illuminate per
display pixel - just like an OLED
(Organic Light Emitting Diode)
panel would, only MicroLED
uses inorganic material.
• MicroLED features miniature
length less than 100 µm. Via
mass transfer technology µm–
level trio-color RGB MicroLEDs
are moved onto substrate ,
creating MicroLED display in
various size.
