Some well-known international companies, including Samsung, Apple and Facebook ’s Oculus, have already begun to equip future products with this technology, and various companies and manufacturers have recently begun to apply for various patents on MicrOLED technology. Starting in 2018, as major manufacturers such as Samsung, Sony, and AUO have successively launched Micro LED related conceptual products, the next-generation display technology and application market expected by the industry is accelerating.
However, such a near-perfect display technology seems to have disappeared in recent times. Moreover, in the conferences of major manufacturers including TV, mobile phones, monitors and other display equipment manufacturers, there is no trace. At most, I only saw the display machine at the exhibition.
So, what is the status of this MicroLED technology, which claims to replace OLED? What about the future? To expand on this topic, it is necessary to first introduce to you what MicroLED technology is.
MicroLED is a micro light-emitting diode, which refers to a high-density integrated LED array. The distance of LED pixels in the array is on the order of 10 microns, and each LED pixel can emit light by itself.
It is the miniaturization of the traditional inorganic LED array, each LED pixel with a size of 10 microns can be independently addressed and lit. Simply put, it can be seen that the size of small-pitch LEDs has been further reduced to the order of 10 microns. The display method of the Micro LED is very direct. Connect the 10 microns LED chip to the TFT drive substrate, so as to achieve precise control of the brightness of each chip, and then achieve image display.
The power consumption of MicroLED is about 10% of LCD and 50% of OLED. Compared with OLED, to achieve the same display brightness, only about 10% of the coating area of the latter is needed. At the same time, the brightness can reach 30 times that of OLED, and the resolution can reach 1500PPI (pixel density), which is equivalent to 5 times that AppleWatch adopts OLED panel to reach 300PPI. Therefore, only from the comparison of various data, there is an opportunity to replace the current mainstream display technology.
However, to a certain extent, the most obvious manifestation of a technology's immaturity in the market is the high cost of its products. This is the case with MicroLED.
At present, MicroLED is limited by some bottleneck technologies, especially in the mass transfer process. Even if the industry can make breakthroughs, it will take time to really improve the yield and reduce costs. In addition, Micro LED also has a big problem is the full color, the consistency of the emission wavelength.
In addition, the improvement of MicroLED's entire process chain is not a result of Asahi, even three to four times that of current LCD or OLED panels. There is no doubt that this will increase the cost of the product a lot, and even affect the investment of the entire industry. After all, many manufacturers are constantly expanding the production line of OLED screens. Therefore, the manufacturing price and cost of MicroLED are also much higher. It should take time to mass-produce and replace existing products.
Therefore, this is why you will see various figures of MicroLED in large electronic exhibitions such as CES and IFA, but you have never seen any manufacturer really sell this type of display products on the market. However, in the long run, high-end display panel manufacturers will take MicroLED as the main research direction in the future, and MicroLED is likely to become the ultimate goal of the entire display industry. https://www.i-simu.com/
