Name of Prototype | 0.39-inch single-chip full-color Micro-LED micro-display | ||||
Introduction of the prototype | The realization of full-color display on single chip is one of the main bottlenecks restricting the application of Micro-LED. Through the QD color conversion technology, Raysolve realizes a high-resolution and highly efficient color conversion layer on blue GaN Micro-LED arrays by standard lithography process. The blue light is converted into red and green by the QDs color conversion layer, so as to realize full-color display on a single chip. Moreover, light blocking structure is applied to suppress the light crosstalk among neighboring pixels, thus higher contrast and color saturation are obtained. In the meantime, the photolithographic QDs technology can effectively solve the problem of the light efficiency and brightness of the original red light, so that the overall brightness of the chip has a qualitative improvement.The market deployment of existing AR “Helmet” is hindered by its size, weight and brightness. Realizing monolithic full-color Micro-LED micro-displays is a must for the development of real consumer-level AR glasses. | ||||

| Name of the Prototype | Wearable Smart Foot Health Monitoring System | ||||
Introduction of the Prototype | Wearable health-monitoring systems have received continuous attention from both academia and industry in recent decades. We have developed a sensor using low-cost and flexible carbon fiber as the pressure sensing material, which has a wide pressure detection range (0-1600kPa), high sensitivity (500-1600kPa, 0.01kPa-1 relative sensitivity), high stability (over 3000 pressure cycles), overload resistance (capable of withstanding MPa-level compression), fast response and recovery time (82ms), and good waterproof performance (able to work normally after being soaked for 12 hours). By combining circuit design and single-chip microcomputer development, we have created a highly integrated, flexible and wearable intelligent insole with remote monitoring capabilities (transmission distance greater than 500m), which can integrate up to 104 pressure sensors in a single shoe. By digitizing and regionalizing the entire foot pressure distribution, we have developed a motion recognition algorithm for different foot regions, achieving multi-motion pattern recognition with an average recognition accuracy of 83.32%. Our product provides more development space for the future of sports and health industry and delivers excellent performance and experience to users. | ||||

| Name of Prototype | 0.13" Micro-LED MicroDisplay Module | ||||
Introduction of the Prototype | Micro-LED technology refers to the display technology that takes self-luminous micron level LED as luminous pixel unit and bonded to the driving panel to form high-density LED array, namely LED miniaturization and matrix technology. It refers to the integration of high-density mm-size LED array on a chip, which is the result of thin-film, miniaturization and matrix of LED. Micro-LED generally requires chip size less than 50μm, and each pixel can be individually addressed and individually driven to emit light. Compared with LCD and OLED, Micro-LED is considered as the ultimate display technology due to its advantages of self-lighting, high efficiency, low power consumption, high integration, high reliability, and all-weather operation. In terms of application, Micro-LED can be applied in different fields when using different bonding technologies. When using monolithic bonding and silicon-based CMOS driving technologies, Micro-LED microdisplays of small size can be produced by virtue of its characteristics of ultra-high brightness and ultra-high pixel density. It can be used in AR/VR/XR, car and outdoor sighting equipment and other fields. Using mass transfer and TFT driven technology, it can produce flexible, transparent and curved screens for applications in smart wear, mobile phones and TVs. The 0.13" Micro-LED microdisplay module, with a pixel size of 2.5μm, is a major innovation in chip fabrication. With the decrease of pixel size, the difficulty of driving circuit design and layout preparation is greatly increased. Based on CMOS active driving technology, this product finally achieves 10000PPI display, and each technical index of the product is in the leading position in the industry. | ||||

| Name of Prototype | NED Freeform Diamond Pro AR optical module | ||||
Introduction of the Prototype | Freeform Diamond Pro AR optical module, based on the self-developed freeform surface prism optical scheme, innovatively adopts the form of main prism folding optical path and compensation lens to achieve optical see-through near-eye display. The product takes prism as the main component, in which the light is propagated in the form of internal reflection, and the form is more compact. The introduction of freeform surface technology not only reduces the complexity of configuration, but also increases more freedom of design for the system, effectively ensuring the clarity of the display image. The product has the advantages of high light efficiency, compact size and high image quality, and its shape is close to that of ordinary glasses, with a more comfortable see-through field of view. The monocular module is only composed of two lenses and a micro-display. The optical resin lenses are manufactured by injection molding process, which has the advantages of low cost, stable quality and high feasibility of mass production. In the design, the problem of the small vertical see-through field of the previous freeform prism scheme is solved, and the larger see-through field and the thinner system structure are realized. | ||||

| Name of Prototype | Thermal stable polarized quantum rods film | ||||
Introduction of the Prototype | Optical polarization characteristics have been widely used in liquid crystal displays, optical modulation, and polarization detection. However, the efficiency of polarizers is still less than 50%, and the efficiency of polarized light sources (such as leds) is still low.

| Name of Prototype | Naked eye 3D medical microscope | ||||
Introduction of the Prototype | The naked eye 3D display technology allows for truly immersive viewing without requiring the observer to wear any auxiliary equipment. Traditional medical 3D display system still requires practitioners to wear auxiliary 3D equipment, such as VR/AR headsets, polarized glasses, etc., which is very unfriendly to long-term users. Based on the real-time rendering naked eye 3D display system of ultra-high-definition binocular camera, this project realizes the real-time rendering and display of binocular video signals with the resolution of 15.6 ", FOV80°, 30/60Hz and up to 7860*4320, which can be widely used in internal medicine, dentistry, medical education, training and other fields. At the same time, the binocular real-time rendering system can also be used in the fields of 3D interactive games, digital human interaction, industrial digital twinning, military and so on. | ||||
