>> Micro LED technology bottleneck analysis: can challenge LCD and OLED? 16th,Sep,2017
It is reported that in the fall of the launch of the decade version of the phone, Apple will be the first time in the history of the use of organic screen (OLED), by the Samsung display company supply. However, according to foreign media reports, Apple has also acquired a micro-LED display technology company, and its own in the display panel research and development, which makes Samsung, LG and other screen manufacturers have some concerns.
According to the US Science and Technology News website Apple Insider reported that later this year, Apple will begin production of micro-LED display, initially for the third generation of Apple watches, Apple's current use of organic watches.
In the display panel area, Apple has no technical reserves in the past. But in 2014, Apple acquired a company called LuxVue, won the company's micro-LED technology, and in the past few years, this display panel technology began to lead the industry attention, and Apple is also active Development.
Micro-LED is promising to become a new generation of display technology
In addition to LCD, the organic screen is considered an alternative to LCD panels. Before Apple, Samsung Electronics and many other mobile phone manufacturers have begun to use organic screen, this screen quality better, more power, thinner thickness, and can be bent design.
In fact, organic screen technology has been around for many years, but its cost is difficult to decline, but the past few years, organic screen production technology breakthrough, lower costs. The market has been a lot of organic screen mobile phones and televisions, the future will be more related manufacturers.
Micro LED display (Micro LED display) for the new generation of display technology, the structure is a miniaturized LED array, which is the LED structure design for thinning, miniaturization and array, so that the size of the current mainstream LED size Of the 1%, each pixel can be addressed, a separate drive light, the distance from the original pixel level down to the micron level.
Following the characteristics of LED, Micro LED advantages include low power consumption, high brightness, ultra-high resolution and color saturation, fast response, ultra-power, longer life, higher efficiency, the power consumption of about LCD 10%, 50% of OLED. And with the same self-luminous display OLED compared to 30 times higher than its brightness, and the resolution of up to 1500PPI (pixel density), the equivalent of Apple Watch OLED panel to achieve 300PPI 5 times, in addition, with Better material stability and no image mark is one of the advantages.
And large size, is the cost of competition, Micro-LED competitive advantage is not obvious. Micro-LED in the large-scale aspects of the challenge is very large, so many years, compared with the LCD, OLED, LED in the cost and did not form an advantage, and Micro-LED from the actual input and progress, Micro-LED influence Imagine so much. LCD cost is low, yield stability, competitiveness is very strong. Like the LCD and PDP, LCD and Micro-LED future competition is not only related to the technical competition, but also involves the industrial chain and ecological competition.
Process type and technology development
For the semiconductor and chip process miniaturization has now reached the limit, and in the manufacture of micro-shrink there is still a considerable room for growth, for the Micro LED process, the main present is divided into three categories: Chip bonding, Wafer bonding and Thin film transfer.
