Developed by Mitsubitshi Electric Research Laboratories,[1] a privacy-enhanced computer display allows information that must remain private to be viewed on computer displays located in public areas (i.e. banks, hospitals and pharmacies) by employing the use of both ferroelectric shutter glasses and a unique device driver.
[1] Prior to the invention of privacy-enhanced computer display by the Mitsubishi Electric Research Laboratories, several static systems that serve a similar purpose were established.
[2] Static system is a preventive tool that protects the public computer display without any dynamic alterations to the video stream itself.
The authorized users who have access to the confidential information need to wear a polarized sunglasses to see the screen.
A final issue is the decline of the CRT and the rise of the LCD in display technology, because nearly all LCDs are too slow to support the 120 Hz or faster refresh rate needed for this privacy enhancement to work.
