Japan's Transparent Toilet Malfunction: Full Exposure!

The well-known "transparent public toilets" in two parks in Shibuya District, Tokyo, Japan were recently discovered by Internet celebrities that the opaque function of the glass outer walls is out of the question. Even if there are people inside the public toilets, the glass outer walls are still close to transparent, allowing "all things to be seen" from the outside. (Please click on the link）

Transparent public toilets, which have triggered a lot of discussion, why on earth lead to the release of opaque functions?

First of all, we can understand from the control principle that transparent public toilets use PDLC technology. The concept is that when electricity is turned on, the direction of the liquid crystal molecules is changed so that light can penetrate freely, creating a visual transparency phenomenon. It should be noted that the material itself will also have an operating temperature. Within the operating temperature range, the liquid crystal molecules can operate normally. When it exceeds the range and the temperature is too high or too low, it may cause the liquid crystal to operate abnormally, and the switching speed may appear to be slower in appearance, which is the phenomenon of abnormal "opacity function" in the article.

In addition, when the PDLC is powered on for a long time, it may also cause the liquid crystal turning speed to slow down. When an abnormal situation occurs, don't worry, contact the supplier quickly, confirm the product specifications, and temporarily turn off the power to allow the atomization function to return to normal. To avoid this situation, if the space is operated less often, it is recommended to use a timer and set it to "off" during "non-operation time" other than the set time. Under normal operation, it is recommended to turn off and restart the switch every 12 hours, which will also extend the service life!
