Korean researchers have developed a technology that reduces the production cost of vertical micro LEDs while improving their optical efficiency.<br />Park Se-young has more. <br /> Micro LEDs have become a strong candidate for use in next-generation displays …with their ultra-low power consumption, fast response speed and excellent flexibility.<br />However, in the past, the manufacturing process had been too costly and time consuming.<br />To solve these problems, Korean researchers have designed their own equipment for producing vertical micro LEDs.<br /><br /> "Vertical micro LEDs have a shorter current path than horizontal thin film LEDs so they emit less heat, have a lower resistance and achieve a higher level of optical efficiency."<br /><br /> The researchers developed flexible vertical micro LEDs by simultaneously transferring 25-hundred thin film LEDs with a thickness of five to 80 micrometers.<br />This can triple the optical efficiency of existing LEDs and solve the problems of their short product lifespan due to heating, low resolution and low reliability.<br />The researchers have also succeeded in controlling animal behavior by inserting micro LEDs into the brain of a mouse.<br />The technology is expected to be applied to various fields such as brain science.<br /><br /> "It can be immediately applied to smart watches, mobile displays and wearable lights requiring low electric power, and it will be able to make a large contribution to the development of biomedical devices as well."<br /><br /> The findings were published in the Nano Energy journal.<br />Park Se-young, Arirang News. <br />
