Optically Clear Resin (OCR) Direct Bonding
The LG Transparent LED film, which applied the OCR bonding method, protects LED pixels stability by fully filling the gap between transparent layers. Compared to Optically Clear Adhesive (OCA) method, which usually perforates the upper layer above each LED pixel to prevent uneven surface and scattered reflection, the LG Transparent LED film fully embraces and protects the pixels resulting in improved durability and a flat surface.
