Micro LED display and its advantages
MicroLED has changed rapidly the world of screen technology. Micro LEDs have the potential to be superior to OLED in many ways and could be the dominant display technology in new products in a decade. In a conversation about MicroLED with Tom's Guide at CES this year, Andrew Sivori, Samsung Electronics America vice president, called MicroLED "groundbreaking." He added that MicroLED is the first "new TV technology in almost 10 years." Most of the people are curious to know what is MicroLED and what are its advantages? We'll answer those questions in this article. So, let's dive into the deep of Micro LED screen technology -
What is MicroLED?
MicroLED is an emerging flat panel display technology. As the name implies, microLED displays consist of arrays of microscopic LEDs forming the individual pixel elements. When compared to the widespread LCD technology, microLED displays offer better contrast, response times, and energy efficiency. MicroLEDs are primarily aimed at small, low-energy devices such as smartwatches and smartphones. OLED and microLED both offer greatly reduced energy requirements compared to conventional LCD systems. microLED is based on conventional GaN LED technology, which offers far higher total brightness than OLED produces, as much as 30 times, as well as higher efficiency in terms of lux/W. It also does not suffer from the shorter lifetimes of OLED.
For an optimal experience with Micro LED displays, it is essential to pair them with high-quality LED drivers. If you're looking for a reliable buying guide for Meanwell XLG series LED drivers, you can explore Bravo Electro's informative blog post on the subject.
Advantages of Micro LED
-
MicroLED is an actual thing, a type of display technology that represents a significant improvement over the LED televisions that dominate today’s market.
-
The costs of the traditional LED package is to account for the greater share in display modules.
-
Micro LED requires no lead frame and metal wire and therefore reduce packaging costs on traditional SMD LEDs.
-
Micro LEDs provides high wavelength uniformity, for fine pixel pitch display-used LED demanded even greater uniformity.
-
The super small LEDs in MicroLED displays are more efficient at turning electricity into photons. Basically, they produce more “brightness per watt” than either traditional LCD or OLED displays. It’s still a new product that hasn’t been fully commercialized yet, but some estimates say that MicroLED should use about half the energy as OLED to produce an equivalent brightness. Other estimates say the energy savings will be much greater.
-
PCB is required to be customized, using thin line width/ spacing and drilling. The customization of ultra-high density circuit is used for supporting Micro-LED’s high-resolution display.
-
Compared to bracelet and watches, driver IC of the display also requires customization, including integration of driver IC and flyback circuit that simplifies PCB design. Doing so will improve photoelectric transformation efficiency and save space. The driver IC module also reduces design and manufacturing costs.
-
The LEDs in MicroLED displays are far less susceptible to this than the organic compounds in OLEDs, or the liquid crystal layer in traditional LCDs. Burn-in shouldn’t be a concern for most MicroLED products.
-
Micro LEDs have switching speeds that sound more like microchips than displays-they’re measured in the nanoseconds (billionths of a second). The super high resolutions in tiny sizes, combined with ultra-fast switching speeds, make Micro LEDs perfect for VR and AR headsets.
-
Micro LEDs are said to be capable of a broader range of color, which means wider color gamuts, and they can be more precisely controlled for better color accuracy.
-
Micro LED ditches the backlight, favoring instead extremely tiny LEDs, each of which comprises a red, green, and blue sub-pixel that can provide its own light. It also swaps in an inorganic material - gallium nitride, for those keeping score at home.
-
MicroLED displays will also offer a longer lifespan than current OLED panels.
