News on March 25th, Beijing time, Japan Display has developed a transparent screen that can be operated in a non-contact manner. The LCD panel company Japan Display (JDI) has developed a non-contact transparent touch screen that can be seen on the other side of the screen. You can operate without touching the screen by just waving your finger. In the case of the spread of the new crown epidemic, it is expected that it can be embedded in anti-droplet partitions set up at checkout counters in stores and used. Nippon Display plans to open up new markets for LCD panels.
This kind of screen is as transparent as a glass plate when it is not energized, and an image will appear when it is energized. Users can select the icons displayed on the screen, or move their fingers left and right to scroll the screen, operating like the touch screen of a smart phone. Its working principle is to perceive the change of the "electrostatic capacity" between the human and the panel. Operate your finger at a distance of 5 cm from the screen, and the screen will respond.
The trial product developed by Nippon Display is 12.3 inches. The envisaged use is to embed a transparent touch screen into an anti-droplet partition. For example, display options for payment methods or display QR codes for mobile payments on anti-spray partitions installed at the cashiers of convenience stores. It is expected that places such as medical facilities and food factories that require strict sanitation management will also have demand for such non-contact transparent touch screens.
