Moisture Protection for Micro-LED Displays

Display device with improved encapsulation to prevent water and oxygen ingress into the display and degrade the device. The encapsulation involves covering the side surfaces of adhesive layers used to attach components like light-emitting diodes (LEDs) to the display substrate. This prevents external water and oxygen from penetrating through the adhesive sidewalls. The encapsulation is achieved by adding an extra encapsulation substrate that overlaps and contacts the adhesive layers. This ensures the side surfaces of the adhesive layers are fully covered. The additional encapsulation substrate can also have grooves in the upper portion to reduce stress when bending the encapsulation structure.
