Micro assembled hybrid displays and lighting elements

The disclosed technology relates generally hybrid displays with pixels that include both inorganic light emitting diodes (ILEDs) and organic light emitting diodes (OLEDs). The disclosed technology provides a hybrid display that uses a mixture of ILEDs and OLEDs in each pixel. In certain embodiments, each pixel in the hybrid display includes a red ILED, a blue ILED, and a green OLED. In this instance, the OLED process would not require a high resolution shadow mask, thereby enhancing the manufacturability of OLEDs for larger format displays. Additionally, the OLED process in this example would not require any fine lithography. The OLED subpixel (e.g., green subpixel) can be larger and the ILEDs can be small (e.g., micro-red and micro-blue ILEDs). The use of small ILEDs allows for other functions to be added to the pixel, such as micro sensors and micro integrated circuits.
