With the continuous decline in the cost of LED display and the gradual maturity of solutions such as small-pitch display, the LED display market is ushered in a stage of rapid growth, industrial transformation and acceleration are accelerating, and screen enterprises pay more attention to technology and product deep penetration, especially Mini LED. The emergence and maturity of /Micro LEDs is giving birth to a broad market space.
Recently, industry technology has made new breakthroughs in various fields. New technologies, new products, and new applications are emerging one after another. What are the specifics? Let's take a look at it with Xiaobian:
Point pitch P0.49mm Mini/Micro LED display module
Ruifeng Optoelectronics has announced a new development of the new generation of μLED display technology, the Qiao Ge K2 series, which is a full μLED chip package with a pixel pitch of 0.49mm, which realizes the current global dot pitch density μLED display module technology. Another innovative breakthrough. Moreover, the display module is an independent illumination and color mixing of the RGB LED chip, and has the characteristics of wide color gamut, high color purity, and true color reproduction.
"Curlable" and "Transparent" AM Mini LED displays
Recently, Innolux has released the world's earlier Rollable AM ​​Mini LED display with high brightness, good grayscale performance, high color saturation, high definition dynamic image quality, and the advantages of simple storage and installation. It replaces the traditional projection display and has the advantage of being curlable. It can be applied to all kinds of curved displays at the same time. At present, it can contact the brand customers to apply the curlable display, and the business opportunities are unlimited.
In addition, optimistic about department store window, home appliances, vending machines, display cabinets, windows and other transparent display applications to drive consumer opportunities, Innolux and brand customers to develop ultra-high brightness, high color saturation, high penetration AM Mini LED Transparent display. Compared with OLED transparent displays, AM Mini LED transparent displays outperform OLEDs in terms of brightness and environmental reliability. AM Mini LEDs will gain advantages in semi-outdoor or outdoor transparent display applications.
Silicon-based GaN high-profile micro LED display technology
Recently, Dr. Wei Sin Tan, Plessey Epitaxial Film Business Director, said that an important milestone has been achieved in the development of single-chip Micro LED display technology. Plessey has successfully successfully used its silicon-based GaN single crystal micro LED wafer with JDC's eSP70. Silicon-backplane technology enables wafer-level bonding to enable Micro LED display technology with addressable LEDs.
For many years, Plessey has been promoting the development of this technology by considering the single-chip multi-pixel LED Micro display as the future of outdoor visual augmented reality display glasses. It is reported that the addressable Micro LED array is a monochrome current-driven pixel array measuring 1,920*1,080 (Full HD) with a pitch of 8μm. Each display requires more than two million individual electronic bonds to connect the Micro LED pixels to the control backplane.
3D LED package new technology
Earlier, Guoxing Optoelectronics released a new LED technology for LED lights, a new three-dimensional packaged LED. It is the new "high-precision" technology achievement of the National Star White Light Division in the field of LED lights. It adopts a three-dimensional column-shaped integrated three-dimensional structure, light and heat. The coupling design has three-dimensional 6-sided light emission, and has three heat dissipation structures of evaporation zone, heat insulation zone and condensation zone, which perfectly solves the technology that the traditional planar LED light source chip has low packing density, the absorption of adjacent chips is serious, and the light angle of more than 180° cannot be realized. Difficulties and pain points.
Guoxing's new three-dimensional packaged LED has outstanding advantages such as large illumination angle, high integration, high brightness, high reliability and excellent heat dissipation performance. Its brightness is 45% higher than that of planar package light source, and the integration degree is 10.7 times that of planar package light source. The density is 18 times that of the flat package light source. Its outstanding advantages have been tested and verified by a brand of headlight assembly system, leading to a new trend of high reliability of the lamp.
LED embedded bandage can cure chronic wounds by blue light
According to reports, scientists have demonstrated the antibacterial and anti-inflammatory effects of blue light and embed blue light into elastic bandages to heal wounds. MEDILIGHT is a European research project that develops smart and wearable medical devices and has demonstrated prototypes of LED embedded lighting solutions for the treatment of chronic wounds.
The MEDILIGHT project showed that in addition to the antibacterial effect, the anti-proliferative effect of blue light has been clearly confirmed, demonstrating that blue light prevents excessive differential alienation in the premature healing phase. The team further demonstrated that blue light can effectively activate key skin cells through another suitable light dose, thereby accelerating the final wound healing process. The research team believes that the prototype of this LED-based smart wearable system will further pave the way for the commercialization of potential future phototherapy-based wound healing devices.
As the industry has said, "The future is the 5G era, and the 5G era is the world of screens. The screen as the interactive port of the IoT will continue to increase, which will open up new growth space for the LED display...", of course, the premise is ready Real hardcore technology and products.
UV Inkjet coding machine
HAE UV Inkjet Coding Machine UV inkjet system adopt industrial piezoelectric drop-on-demand inkjet technology to carry out a revolutionary innovation on the original personalized card production process in the card industry, whether it is production speed, printing quality, production cost or The scratch resistance of the product has been greatly improved.
Online UV Ink inkjet printer Mainly for labels of various materials, variable information such as Chinese characters, letters, numbers, one-dimensional bar codes, two-dimensional bar codes, etc. can be sprayed on the label and roll film. The printed content has a bright and shiny appearance, which improves the value of the label. When producing standard labels, the speed is 90 meters per minute, UV ink inkjet coder can be installed on various packaging lines, printing lines, rewinders, and slitting machines.
Aiming at the printing material, customized a UV super black and fast-resistant ink that is very suitable for printing on the surface of the card, which further improves the performance of the product. This UV environmentally friendly ink can be printed on cards with dirty surfaces or small scratches. It can be wiped with solvents such as alcohol and propanol. At the same time, it can be cured with less UV energy, reducing energy consumption.
