LCD Screen Can Monitor UV Levels and Take Your Fingerprints

AU Optronics Corp, one of the top three manufacturers of thin film Liquid Crystal Displays (LCDs), have developed a LCD screen which has the ability to take your fingerprint or monitor UV levels on the environment (the UV thing is kinda weird, they hope to market it to women worried about too much skin exposure to UV rays).

The LCD screen is able to scan a fingerprint due to the high amount of sensors built into the pixels themselves. “The LCD panel is mounted with optical sensors and a detection circuit. Each pixel is equipped with four sensors.” The high pixel to sensor ratio allows it to scan a fingerprint only a few seconds after a finger is placed on it.

The scariest issue about all of this is the fact that surfaces, which we thought were simple, are becoming even more complex. This is a huge issue when you consider biometric information (fingerprints, DNA, iris scan) can easily be gained by technology that used to just make thinner TVs possible. It makes you wonder how decades from now people are going to protect their identity when the technology around them records everything about them.
