How to achieve the method of high-brightness red Micro LED has always been a problem in the industry, and it is a key barrier to the industrialization of Micro LED micro-display technology. JBD's 0.13-inch red microdisplay broke through efficiency limits and achieved a brightness level of 500,000 nits, setting a new brightness record.
The launch of JBD red high-performance products will help Micro LED technology to further expand in various scenarios such as sports optics, vehicle display, and near-eye display, and also lay the foundation for Micro LED's full-color AR application.
JDBD's red light products are self-emitting microdisplays based on its invention of hybrid integrated semiconductor technology, which integrates AlGaInP semiconductor materials with silicon-based CMOS at the wafer level. AlGaInP semiconductor material is the key to achieving high-performance red light, and it has the semiconductor band gap that best matches red light, and is the most mature semiconductor material in the industry for making red LEDs.
It is reported that JBD has been adhering to the AlGaInP-based red light Micro LED technology route for many years, and through continuous in-depth research and development, it has made simultaneous efforts at both ends of material growth and chip technology research and development, breaking through the bottleneck of red light size effect and achieving a huge improvement in red light performance.
In the 0.13-inch red light chip launched by JBD, the pixel size is only 4 microns, and the Micro LED light-emitting point is only 2 microns, but it can easily load the microampere level of driving current to produce 500,000 nits of ultra-high brightness. In comparison, QD-LED and Micro OLED, which are based on quantum dot color conversion, as the other two mainstream self-luminous micro-display technologies, according to the brightness level of only a few thousand nits currently disclosed, JBD's red light chip has achieved dozens of times the performance surpassed.
In addition to ultra-high brightness, excellent display quality and reliability level are the key to the commercialization of Micro LED microdisplays. JBD's AlGaInP-based red light products achieve extremely narrow spectral widths and excellent color purity. As shown in Figure 4, the spectral half-wave width of this product is only about 15nm, which is much lower than the typical half-wave width of nearly 50nm for InGaN-based red light and nearly 30nm for QD-LEDs.
In addition, excellent display quality is inseparable from the close fit between the CMOS backplane and Micro LED. With the blessing of JBD's patented IC backplane technology, red light products achieve >95% pixel-level display uniformity, > ultra-high contrast ratio of 100,000:1, and
All in all, the mass production of JBD high-performance red Micro LED displays completes its series of micro-display products in multiple colors, and will strongly expand its applications in monochrome to full-color multi-field applications. So far, JBD has achieved more than one million micro display panel shipments, continuously providing core display components to the downstream Micro LED terminal application industry chain, accelerating the application of Micro LED technology in near-eye display AR/VR, HUD head-up display, sports optics, 3D printing, micro-projection, light field display and other fields.
