Holders parked under the cloud, in the winter they have to deal with many problems. And it’s not just the ignition problem, but also with the increasingly widespread in the car LCD screens, which due to frost do not work properly. The University of Central Florida scientists have no idea how to handle this.
Most modern cars have built-in central console LCDs that serve the vehicle’s systems. Unfortunately like every liquid crystal display, these also are not resistant to low temperatures. So if our car parked under the cloud, then in the winter they make a problem, because the frost causes the image becomes blurred. On the other hand, in the case of touch screens, the response time is considerably longer.
Researchers at the Central Flordy University, led by Shin-Tson Wu, professor of optics and photonics, work with a colleague of the Modern Chemistry Research Institute in the Chinese city of Xi’an and the Japanese DIC Corporation to work on a completely new mixture of liquid crystals that would withstand low temperatures. .
Three different blends have been developed in the experiment that are more resistant to low and high temperatures. Professor Wu says they are still transparent at temperatures above 100 degrees Celsius and their melting point is below 40 degrees Celsius.
According to European standards of LCD screens, to avoid image blur, pixel brightness change time can not be greater than 200 ms at -20 degrees and 300 ms at -30 degrees. The combination created by Shin-Tson Wu at both temperatures has a response time of only 10 ms, so it is more than 20 times faster than the currently produced displays.
Another benefit of the new blend is a threefold higher pixel density and higher brightness. This will improve the visibility of the Head-Up displays especially during the day when the sun’s rays may be limited.
