In 2017, Mini LED.html' style='font-weight: bold;color: #900916;border-bottom: 1px #900916 dotted; padding-bottom: 2px;' target='_blank'>LED, Micro LED and OLED In the display field, it became a "red fried chicken". From the upstream chip companies, to the midstream package, to the downstream display application companies, they have followed the “windowâ€.
Compared with MicroLED, Mini-LED technology is less difficult, easy to mass-produce, and can develop a large number of LCD backlight market, and the product economy is better. In 2017, large-scale manufacturers such as Jingdian, Longda Electronics and Sanan Optoelectronics successively deployed to promote the rapid development of Mini LED technology. However, many companies believe that the Mini LED is only a transitional product, and the future of the display will eventually belong to the Micro LED.
What is the charm of Micro LED, so that the industry is so persistent? It is understood that Micro LED is to thin, miniaturize and array the LED structure design, and the volume is about 1% of the current mainstream LED size. Each pixel can be addressed and illuminated separately, and the pixel distance is reduced by the order of magnitude. Micron, and has the advantages of low power consumption, high brightness, high resolution and color saturation, faster response, longer life and higher efficiency. However, industry insiders predict that real Micro LED products will not be ready for mass production until 2020.
Micro LEDs are used in a wide range of applications, both in large and small sizes. But at least for now, OLEDs occupy an important position in the display field. Some insiders predict that in the high-end display field, OLED will have a market share of 30% in the next five years, and the market share will reach 45% in the next eight to ten years.
However, at this stage, Mini LED, Micro LED and OLED have been “pursued†by many companies. High-tech LEDs list the layout of some manufacturers to explore the hotness of Mini LEDs, Micro LEDs and OLEDs.
Mini LED
Compared to traditional LED displays, Mini LEDs offer the opportunity to achieve higher dynamic contrast and wide color gamut effects. Due to the high brightness and high dynamic contrast of the Mini LED, there will be opportunities to import high-end TV products.
