Smartphone and tablet screens can be very easy to break and painfully expensive to replace.<br />Here's some good news,... Korean researchers have developed a display material that can mend itself when broken.<br />Here's Park Se-young with the details. <br /> This luminous element is used to make displays for electronic devices.<br />When connected to an electrode, it emits bright light.<br />The element emits brighter light with increased voltage, but it soon becomes damaged and parts of it turn black.<br />But when the power is switched off, the black patches disappear and the element's luminous properties are restored.<br /> "The display became damaged from a current leakage. Through experiments, we found that the damaged display made a one-hundred-percent recovery of its original performance …after about a minute of self-healing."<br /><br /> The self-healing luminous element developed by Korean researchers is high in viscosity and elasticity.<br />When the material is cut in two, it starts to repair itself in about three minutes.<br />After 30 minutes, the two pieces have become one and the element's luminous properties fully recover.<br />The researchers plan to use this element to develop displays for wearable devices.<br /><br /> "Wearable displays have to be very flexible, and since the human body makes a lot of movements, the display should be easily restored when damaged."<br /><br />However, screens made from the self-healing luminous element use ten times more energy than ordinary screens.<br /> The researchers plan to raise the efficiency of the element before its commercialization, …and extend the battery life of devices with flexible displays. <br />Park Se-young, Arirang News. <br /><br />
