Revolutionary Display Technology
As the leading manufacturer in MicroLED displays, JBD has an impressive portfolio of intellectual property and know-how in manufacturing MicroLED microdisplays.
AmµLED™ MicroLED displays are manufactured using the following technology blocks.
Monolithic Hybrid Integration
JBD's AmµLED™ MicroLED displays are manufactured in a wafer level process using standard semiconductor lithography process.
The III-V semiconductor wafer after epitaxial growth is bonded to the Intelligent Silicon-IC backplane to create MicroLED dice on a wafer level which are singulated and packaged as a microdisplay.
This process is called Monolithic hybrid integration and it is the only viable technology that enables the mass production of high pixel density displays (up to 10,000 PPI) with pixel pitch as small as 2.5 µm
High PPI microdisplays are almost always used with collimating, projection or magnifying optics.
Just like OLED displays, the inherent light distribution of MicroLED displays is near Lambertian.
To ensure optimum coupling efficiency wit optics JBD's AmµLED™ MicroLED displays have Pixel Optics™ which is an array of micro lens created using standard lithography processes. Pixel Optics™ collimates the light distribution of JBD's AmµLED™ displays, With Pixel Optics™ almost 3 times the amount of light in captured in a solid angle of 20° compared to a near Lambertian emission.
Intelligent IC Backplane
MicroLED displays have unique pixel driver requirements.
To achieve the ultra-high brightness and brightness uniformity, the pixel drivers in JBD's Silicon IC backplane are capable of delivering very high pixel currents and have a constant current architecture.
The Silicon IC backplane is manufactured using CMOS processes and has a lot of intelligence built offering flexibility and a host of image correction features.
JBD's polychrome engines uses monochrome red, green and blue displays and a custom designed X-cube.
The X-cube combines the light from the 3 panels and reproduces rich and saturated colour images much like a 3 x panel high-end projector.
The polychrome engines are available as a polychrome projector with a lens barrel that produces a collimated beam of light with a FOV of 30° (diagonal) for diffractive waveguides. For reflective waveguides the polychrome engine is also available as an assembly of the 3 x displays with the X-cube.
