Project Description

JDC Micro LED Start Kit

LEDs are the industry-standard for backlighting liquid crystal displays (LCDs). LEDs achieved their dominant position because they have a proven high luminous efficiency, low cost, and long lifetime.

Technological progress has pushed LEDs to the point where they are small enough to be used a self-emissive display pixel. These tiny LEDs are known as Micro LEDs or μLEDs. Micro LEDs deliver higher contrast ratios, more brightness, and faster response times than LED-backlit LCDs and Organic LEDs (OLEDs).

The key technologies required for Micro LEDs are the LED chip process, LED transfer process, LED epitaxy, silicon backplane, and driver circuitry.

JDC Silicon Backplanes

Jasper Display Corp. (JDC) offers the backplane and driver platform that allows LED partners to develop their own complete display hardware and software systems. JDC’s silicon backplane uses pulse width modulation (PWM) to digitally and directly drive displays; proprietary modulation patterns can be used as desired.

Proven for both monochrome and full color Micro LEDs, JDC’s backplane reduces development cost, risk, and time-to-market cycle and helps customers to meet their development goals.

The silicon backplane is a digitally modulated, versatile addressable active matrix. Our highly configurable driver supports a wide array of modulation schemes while maintaining constant current LED drivers. The benefits of using JDC’s backplane are as follows:

  • Smallest pixel size

  • Self-emissive

  • High efficiency

  • High brightness

  • High contrast

  • Rapid response time

  • Long lifetime

Several wafer products are available, each of which contain unique silicon backplanes targeted for a variety of applications.

Our Micro LED customers leverage their LED epitaxy and LED chip process technology and use our Micro LED kit to build a complete product. The transfer and bonding of the Micro LEDs can be completed via the customer’s internal capabilities or JDC’s established ecosystems.

JDC can support customers up to light up successfully and beyond. Our customers have already used their development model to demonstrate 0.55” and 0.7” Micro LED displays. JDC’s silicon backplanes can support a wide-variety of applications, ranging from low-power, high resolution displays to high-power lighting.
