Using LCDs to gather Energy

August 30, 2011 · Print This Article

Keeping electronic devices powered is an ongoing concern, particularly as the number of electronic devices proliferates. Researchers at UCLA have developed a liquid crystal display (LCD) that incorporates photovoltaic polarizers that can convert sunlight, ambient light, and even its own backlight into electricity to potential the device.

Polarizers are what makes the display in an LCD operate, by controlling the amount of light that passes through from the backlight to manufacture the display.

The new material, called a polarizing organic photovoltaic film increases the efficiency of display and allows for charging of the device in bright light.

Obviously, the backlight isn’t going to supply suitable light to potential the device infinitely enlarged. But the researchers say that much of the energy lost from backlights can be saved with the new polarizer. “From the point of view of energy use, current LCD polarizers […]
