3MTM Quantum Dot Enhancement Films (QDEF) increase the color gamut of standard LCD displays by roughly 50% through optical down conversion of blue light to narrow bandwidth red and green light. 3M’s UltraBarrier Film Technology encapsulates and stabilizes the environmentally sensitive light-emitting materials, thereby enabling excellent white point and brightness stability, and product lifetime. In this presentation, we will present a general overview of 3M QDEF, discuss UltraBarrier development for 3M QDEF, and compare 3M QDEF product performance to standard LCD displays.
