New technology in color display on the screen

A new form of screen that is doubled the amount of pixels just like a solar cell and can enhance the energy efficiency of mobile phones and electronic reading devices. The technology can also be used in larger screens, becoming billboards capable of absorbing energy or decorative solar panels.

Photovoltaic reflectors in color filters are basically colored like solar panels, which act as energy absorbers on the pixel screen. They can enhance the display efficiency of the screen and lead to the introduction of solar panels or decorative billboards more efficiently. (Jay guo).

Jay Guo, a professor at the University of Michigan at the Department of Electrical and Computer Science Engineering, has developed photovoltaic color filter reflectors that convert light into electricity. The research has just been published in the recent edition of ACS Nano .

In traditional LCD screens, he says, only less than 8% of the backlight light is actually transmitted to the viewer 's eye, the rest is absorbed by color filters and polarized glasses. ' This absorbed light is completely wasteful and also makes the screen heat up, you can feel it when you touch the screen. Why don't we think about absorbing this amount of energy? '

Guo had a bit of success in his research. His new filter can convert about 2% of the energy of wasted light, saving significant amounts of power consumption.

Researchers have created new filters by adding organic semiconductor solar cells to color filters that have both a super-thin and aesthetically pleasing aesthetic similar to those in a laboratory. which Guo created over a year ago. This filter consists of thinly spaced nano metal plates that can resonate, absorb and reflect light of a specific color. Colors depend only on the amount of space between the openings. With a thickness of just 200 nanometers, the new filters are 100 times thinner than traditional color filters, perfectly suited for use in ultra-thin color screen devices in the future.

Currently universities are pursuing patent protection for intellectual property with an article titled " Photonic Color Filters Integrated with Organic Solar Cells for Energy Harvesting ." (Photon color filters are integrated with organic solar cells for energy absorption).
