University of Utah engineers have developed a polarizing filter that allows in more light, leading the way for mobile device displays that last much longer on a single battery charge and cameras that can shoot in dim light. Polarizers are indispensable in digital photography and LCD displays, but they block enormous amounts of light, wasting energy and making it more difficult to photograph in low light.
Organic Light Emitting Diode (OLED) displays are now available not only in smartphones and televisions, but also laptops and PC monitors. We explore how OLED screen technology compares and competes with LCD products.
