The full name of Micro LED in English is "Micro Light Emitting Diode", and Chinese is also called micro light emitting diode.
The size, is the biggest difference between Micro LED and general LED. There is no final conclusion on the specific size standard industry. Taking the definition of Taiwan Jingdian as an example, the general LED die is between 200 and 300 microns, Mini LED (called the predecessor of Micro LED) is about 50 to 60 microns, and Micro LED is 15 microns. And its high resolution and high response speed are better than OLED. Power consumption is 90% lower than LCD and 50% lower than OLED. Low power consumption, which means power saving.
The lifespan is longer than that of OLED, because the O in the OLED, Organic, means the use of organic materials with limited life, which is often referred to as burn-in concerns. The Micro LED uses inorganic gallium nitride material. Micro LED is technically different from Mini LED that it doesn't rely on back-light technology. It's similar to OLED self-luminescence. Micro LED has three self-luminous Micro LED in each pixel.
At present, the biggest technical difficulty of Micro LED is the so-called "Grand Quantity Transfer". What does it mean? In the process, the Micro LED panel is produced that first must manufacture the LED chip, and then transfer these chips to the led substrate one by one. This process is called "Grand Quantity Transfer".
Micro LED displays are usually applied in indoor and outdoor advertising displays now. With the continuous breakthroughs in research and development technology, Micro LED will be widely used in notebook computers, tablet computers, wearable devices and even VR glasses etc.
Affected by the new COVID-19 this year, the major global exhibitions have basically closed, and the release of many new technologies has been delayed. But for the innovative display technology Micro LED, this COVID-19 may let the technology of the Micro LED reverse. And in the first half of this year, there are many industry trends and the development progress of Micro LED for us worth.
The influence of the COVID-19 for the technology and supplying of Micro LED, is the mainly reflected in the delivery of equipment and materials, as well as the development of new production processes. However, due to the difficulties in resuming manufactures in many places, production and sales have been greatly affected, as well as the development of the back-end market has slowed down. Instead, manufacturers can invest resources in front-end industrial R&D. The technology of Micro LED and product development can also make progress and breakthroughs at this time. At the same time, manufacturers are also actively exploring cooperation opportunities, transferring kinetic energy from the end market to upstream technology development, and thus accelerating the breakthrough of Micro LED technology.
