Researchers develop a collection of light energy smart phone LCD screen

Researchers develop smartphone LCD screen for energy collection Sina technology news Beijing Time August 13 afternoon, engineers at the University of California, Los Angeles (hereinafter referred to as "UCLA") have found a way to address the low power of smartphones or laptops,　　It allows the LCD screen to absorb the ambient light to support the electronic product operation. Engineers at the UCLA Henry Samueli Engineering and Applied Sciences (Henry Samueli parochial of UB and applied) have found that they can install polarizer on an electronic product's LCD screen, which allows the ambient light source, Sunlight or even the backlight of the LCD itself is absorbed and converted into electrical energy to achieve the goal of increasing energy efficiency.　　Engineers call it polarized organic photovoltaic panels. Yang, a leading researcher and professor of materials science, says it is believed to be a revolutionary invention that improves the performance of LCD monitors.　　In addition, the polarizer can be used to collect indoor and outdoor light sources, so you can use the sun to recharge the iphone when you go to the beach. The researchers say the current LCD polarizer is not efficient enough. The back light of an electronic product consumes 80% to 90% of the electricity, and 75% of the energy emitted from the backlight is due to the loss of the polarizer. Polarized organic photovoltaic LCD can absorb this part of light energy, and convert it to electrical energy, but the conversion efficiency is not clear. (Puma)
