Techopedia Explains Reconfigurable Tactile Display (RTD)
Whereas liquid crystal display (LCD) screens must remain flat, the irregular shaped display of an RTD may be designed around vents and other obstacles within vehicles, and can be over four times as large as LCDs. One RTD can control discrete functions such as fan speed, temperature, audio volume and radio tuning - all on the same set of controls.
RTDs may also be useful in a hospital setting. They are lightweight, easy-to-clean and would be convenient for patients to use to adjust their bed, temperature controls or other factors related to their comfort.
A September 2010 online patent application lists other possible applications and emphasizes the state of RTD technology. It describes this technology as totally unique and having using application in cars, planes, hospitals, appliances, cameras, keyboards and more.
