Advantages

In the late 1960s, LED light bulbs were only available in red, and they were often used to indicate power-on on televisions and audio equipment

There was a development of yellow and green LED lights during the 1970s. They were used as indicators and in electronics calculators as small displays

By the 1980s, LED light bulbs became more efficient and brighter, making them suitable for signs, barcode scanners, messages displays, and medical equipment

By 2009, LED light bulbs were being manufactured using a new process, lowering manufacturing costs by 90% by saving lots of money

As early as 2012 with a true LED display which uses LEDs to produce images instead of backlighting for other types of displays, such as LED-backlit LCDs, which are often marketed as LEDs

A Printed Circuit Board (PCB) can be integrated directly with LEDs using the Chip-on-Board (COB) LED manufacturing process, almost as if they were printed on the board

(Glue on Board) technology revolutionizes LED displays. It protects LED pixels from external elements and impacts by encapsulating them in epoxy resin. Additionally, this shielding reduces pixel failure risks
