Micro LED really come to the world's first production base in Wuxi

　　Also known as Micro LED or miniature μLED the LED, OLED and the like are constituted by a light emitting diode. This means that both screen technology "luminous self." Each of the red, green, and blue sub-pixels will be its own light, unlike the LCD requires a dedicated backlight. Accordingly, Micro LED and an OLED display can provide the same contrast and color performance in the production can be kept thin.
　　Two different places in a configuration of the LED material. O represents the OLED means organic (Organic), refers to the use of organic materials in the light emitting portion of the pixel in the stack. Micro LED but not the same, this technology is the use of inorganic gallium nitride (GaN) material in the light emitting portion.
　　Such material may provide higher brightness than the OLED products, theoretically up to 30 multiple times. In response speed, contrast, color saturation effect better than the OLED screen. Since the LED is reduced and the material placed in an array, LED display density Micro screen may further breakthroughs. The theoretical data, if the iPhone uses Micro LED 8, the display density can be achieved 1500ppi above.
　　Since the inorganic material, Micro LED OLED screen also on short life problem does not occur. Meanwhile, Micro LED also reduces the need for polarization and the encapsulation layer, so that the panel can be made thinner. White OLED screen must be reduced to achieve high-luminance display power saving effect, a large amount of micro-LED Micro LED arrays, in addition to achieve high brightness, high color saturation and resolution, each pixel can be independently driven, and power , the reaction speed, etc. In terms of power consumption, can be 90% lower than the LCD, 50% lower than the OLED.
　　Micro LED technical difficulty is that too "micro" component should be less than 100 microns, to several millions of tiny LED assembly and attached to a transmission piece panel, is placed between accuracy ± 1.5μm, since the accuracy of the welding demanding, therefore compress high-resolution Micro LED panel size to the smart phone has been the need to overcome the difficulties.
　　Like the TV itself large in size, so the pitch of the LED chip and the package is not too tightness requirements, so to achieve relatively good. Samsung has been demonstrated in two consecutive years at the CES show large size Micro LED video wall, Earlier, Sony has also developed a Micro LED large video wall CLEDIS. If the mobile phone screen or a smart watch, a headset and a smart bracelet, the extremely small size of the panel, with a more complete RGB LED chip monolithic process technology requirements and materials on the wafer material, and ultra-high density packaging technology.
　　Because LED Micro LED is known as the ultimate goal of evolution, and therefore a number of manufacturers continue efforts in this direction over, Apple is one of the leading enterprises Micro LED layout. But would like to complete Micro LED industrial upgrading, relying on only a single company or a single industry is not complete, requires the supplier to the semiconductor industry, and the addition of the display as a whole supply chain, including the LED chip.
　　December 25 came the important message is displayed, Micro LED mass production is expected in the next 2-3 years. Recently, set design, production, sales and service as one of the LED display Riyadh Group and Taiwan's Epistar Group (Genpo New Technology Co., Ltd.), Liang Xi District, Wuxi City, signed a tripartite cooperation agreement. Riyadh Group will set up a joint venture with Taiwan's Epistar Group, officially registered and settled Liangxi District, Wuxi City.
　　The future, the two sides will build the world's first use in Wuxi massive transfer of technology to achieve the minimum size Micro LED display products mass production base, which greatly promote the distribution and development of Micro LED market.
　　Liard said that Taiwan Epistar Group (Genpo New Technology Co., Ltd.) has pioneered the world's "smallest distance" and "minimum package size single RGB LED" display module. The two sides set up a joint venture company, will invest 1 billion yuan early, and construction Mini LED Micro LED display project base. The project includes Mini LED Micro LED design and development of the continent, production and sales of the whole industry chain. Base construction plans to start implementation at the end of December 2019, officially put into operation in 2020 (2023 of production), the future is expected to reach annual sales of 5 billion yuan.
　　Seen in this light, Micro LED's mass-market adoption is not far away from us. As a "testing ground" --Apple Watch Apple's new screen technology, had previously been expected to be the first to spend several Micro LED, while other devices such as iPhone, iPad and MacBook waiting inside Micro LED cost control, adequate production capacity this time , it is likely to transition to Mini LED. All in all, the future will indeed panel technology to Micro LED, of course, and we will see how to make a new round of China will affect the world.
