Mattrix announces new WOLED display built on an a-Si LCD backplane. See the new prototype!


Mattrix’s simple OLET technology platform significantly reduces the cost of displays by enabling the manufacturing of OLED displays using recycled LCD manufacturing lines. This is the next evolution in OLED technology.

AMOLED Displays, LCD Manufacturing

AMOLED is a product differentiator featuring the deepest blacks and most vibrant colors. However, conventional AMOLED manufacturing requires a complex, expensive backplane to drive the emissive OLED frontplane.

Mattrix circumvents what is known as the “AMOLED backplane problem” and allows LCD-TFT array lines to be recycled for AMOLED manufacturing.

AMOLED: Active-Matrix Organic Light-Emitting Diode

Backplane: This circuitry supplies current to the pixel and acts as the pixel’s internal “dimmer switch”

Frontplane: Converts electrical current to light

This simple and highly efficient emissive pixel is enabled by Mattrix’s proprietary OLET (Organic Light-Emitting Transistor) technology:

  • Same simple backplane as AMLCD
  • Up to 3x increase in emissive aperture ratio
  • Highly stable light emission

OLET: the next evolution of OLED

The conventional OLED simply emits light and requires a separate complex backplane to control the drive current.

Mattrix’s OLET combines current control with light emission by integrating 3 components into one highly stable device

  • drive transistor
  • storage capacitor
  • light-emitting stack
