Electroluminescent Quantum Dot-Based Light Emitting Diode for Next Generation Weapon Sites

The need to deliver critical information to the individual soldier making decisions on the battlefield continues to grow in ever-more complex combat situations. Technological advances in weapon sight development now provide the opportunity for soldiers bearing small arms to receive valuable information, in addition to an aiming reticle, such as range and heading to target, identification friend or foe, and available battery life right at the optics of the sight. This proposal addresses the design and development of transparent and miniature matrix displays based on quantum dot light emitting diode (QLED) technology developed by QD Vision to address the shortcomings of displays currently used in weapon sights. At the heart of QLEDs are printable quantum dot emitters that combine the customizable, saturated, stable color and low-voltage performance found in inorganic LEDs with the solution processability of polymers. QLEDs are an emerging printable thin film electroluminescent device technology that is highly desirable for information displays owing to their excellent color, inherent material stability and high efficiency at a low cost of manufacture. The result is a reliable, energy efficient, tunable color solution for displays that is less costly to manufacture and that can employ ultra-thin, transparent substrates.
