At SID's Display Week 2018 in Los Angeles, glō and Jasper Display Corp. (JDC) will, for the first time ever, demo the world's brightest self-emitting display panel. The industry's brightest Micro LEDs (10 μm), developed and integrated by glō, paired with JDC's new silicon backplane, the JD67E2, make it possible to deliver the high brightness and contrast that will benefit the next wave of watches, phones, heads-up-displays (HUDs), and augmented reality (AR) products.

With the JD67E2 the Micro LED industry can take advantage of silicon that is tailored for the needs of high performance Micro LED devices. JDC’s expertise in digitally modulated pixel arrays is the key to their lead in Micro LED-focused silicon platforms. JDC’s history of developing industry firsts has made it possible to anticipate the rise of Micro LEDs. Jeffrey Li, Director of Applications, is excited about the new product possibilities that JDC's new silicon opens up for customers worldwide.

“Our JD67E2 silicon backplane demonstrates our ability to deliver on the promise of Micro LEDs. We’re excited to offer what the industry has been waiting for - silicon that has been designed to realize super-bright Micro LED panels. glō's super-high efficiency Micro LEDs, coupled with their silicon integration expertise, made it possible to demo a blindingly bright self-emissive display - the brightest in the world. Our Micro LED backplane technology can be customized on a per-project basis, allowing us to make specialized silicon suiting needs ranging from low-power AR headsets all the way to projection displays.”

The full-color capable JD67E2 die features a resolution of 1920 x 1080, a pixel pitch of 8 um, and offers excellent current uniformity via a proprietary current source pixel. Uniformity is better than 1% across the array. The device-ready die is now shipping as part of the JD27E2 8" wafer product. JDC’s DFM methodologies enable high-yield volume production of their wafers.

Besides increased brightness and contrast, JDC’s patented, per-pixel pulse width modulation technology is ideally suited to Micro LEDs because digital switching allows for precise and consistent coloring; a single on-state current will deliver a single, stable color. Conversely, an analog drive scheme puts different current levels through the Micro LEDs which is undesirable because wavelengths vary and color shifting occurs.

The JD67E2 is software configurable which allows hardware developers to easily and independently set brightness (via PWM) and color (via current).
