CMOS Backplane

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.
