- Abstract
- We used simultaneous transfer and bonding (SITRAB) technology to fabricate a full-color Mini-LED display on a flexible substrate. SITRAB technology is ETRI's patented technology that integrates transfer and bonding into a single process. We adopted a 25 pm-thick polyimide film as the display substrate. R/G/B Mini-LEDs were arrayed on a glass carrier as a 32 x 32 array. R/G/B Mini-LEDs on twelve glass carriers were transfer-bonded to the display substrate through a tiling process. The fabricated display consists of64 x 64 color pixels, which are connected in a passive matrix.
