LENS (Light Emitting Nanopixel Structure) is a nanoscale pixel array with high resolution and brightness for display applications in AR and VR. LENS’s light source is a reflective nanocone LED which reduces the effects of total internal reflection (TIR), improving light extraction efficiency. A compound parabolic concentrator (CPC) above the nanoLED narrows the outgoing light’s angular spread, ensuring most of the light can be accepted by an imaging system.  Our simulations show that the total light intensity gain from each part of the pixel is at least 3800% of that of a typical flat LED, meaning that battery life duration will be increased by 38 for the same electrical power consumption. Furthermore, this improvement significantly decreases the display thermal radiation by at least 300%.
