We have all employed the LCD technology which uses colour-generating white backlight and liquid crystal filters, and OLED technology, which employs organic compounds that illuminate and colour. LCD displays usually provide a brighter image, but OLED provides better contrast.
Mini-LED is theoretically an LCD cousin. It uses thousands of tiny LEDs instead of just one backlight to emit light; liquid crystals still create colours. It provides something called “local dimming,” so that the luminosity of the certain areas of the show can be controlled. It is also energy-efficient and better than LCD.
LED-backlit LCD displays replaced CCFL (cold cathode fluorescent) ones over the last decade as they offer a number of advantages across many aspects including reliability, lifespan, wider color gamut, smaller physical size, power efficiency, dimming capabilities, and more.
While OLED (organic light-emitting diode) displays have become the current choice for many flagship smartphones and smartwatches like the iPhone 11 Pro and 12 lineup and Apple Watch, mini-LED and micro-LED are set to bring further improvements to displays.
Traditional LED-backlit displays will have anywhere from several dozen to several hundred LEDs. As the name suggests, mini-LED displays make use of miniaturized backlighting and can feature over a thousand full array local dimming (FALD) zones.
Higher ratio of comparison
Less suitable than OLED for burning.
Uses inorganic Gallium (GaN), which over time will not degrade as OLED
Then, which micro-LEDs are there? The dimensions are smaller than mini-variant and the size of a typical LED backlight in an LCD panel is as small as 1/100.
They add the advantages Mini LEDs provide over regular LED LCD displays and provide over 30 times higher luminosity compared to OLEDs.
You devote an LED for each pixel of a panel to the difficult part of producing high-quality micro-LED displays. Engineering Semiconductor explains:
MicroLED is where you minimise them to the tens of microns size. In each pixel, you put one. It’s so much smaller and more complicated to do. It’s harder to position them physically where they are. The LEDs themselves are also harder to manufacture so they are fine.Check Now
