A team of engineers at the UCLA Henry Samueli School of Engineering and Applied Science has concocted a way to build photovoltaic polarizers directly into LCD displays. This would allow the LCD screen itself to collect energy from sunlight, artificial light, and even the display's own backlight and convert it into energy. The researchers say that current LCDs are inefficient, and an LCD's backlight can consume as much as 80 or 90% of a device's power. They explain that 75% of the light created by the backlight is lost through the LCD's polarizers. The researchers' polarizing organic photovoltaic would perform double duty, acting as the LCDs polarizer, while also as a solar panel to create electricity. According to the engineers, the process to create the polarizing organic photovoltaic is easy, and can be done in large scales. The technology could be applied to portable devices such as smartphones, tablets, and laptops, eventually leading to more power-efficient devices that need to be charged via electrical outlet less often.

I'm waiting! ! !

I sure hope this tech comes to market SOMETIME in the next 18 months!!! Just do it already! Smartphones are in dire need of better battery technology!
I know, they have been using the same tech for over a decade.

cool but...

How long till Apple claims to own this technology and motions in court for other manufacturer to stop production? 🙄
Ha, ha 🤣
LOL...you beat me to it! I was g0ing to ask the same question! The US patent office would approve it no questions asked.
