Smart pixel emitters for display
Aledia develops and manufactures a µLED (micro light-emitting diode) display technology based on a unique 3D architecture using gallium-nitride (GaN)-on-silicon nanowires (WireLED™). This technology can be applied in SmartPixels, where each µLED is directly controlled by a CMOS circuit for displays from the size of a smartphone to giant TVs. 

Aledia has developed this technology on 200mm silicon wafers and plans to scale it up to 300mm silicon substrates, giving high manufacturing yield. The purpose will be to provide display designers and assemblers with a disruptive technology as it can remove the need for a TFT layer in displays. This unlock the possibility to design truly flexible displays, giant TV screens, or smart displays (haptic…).

For the first time ever, the display industry can be relocated in Europe if required since the SmartPixel will allow to bypass the Asian monopoly of the TFT layer. µLeds with a pitch of less than 10µm, each one independently controlled by its own control command, will be available as soon as 2024, thus overcoming best experts’ estimates.
