Mini‐LED and micro‐LED are expected to be the next‐generation display by virtue of their diverse applications. In this study, an 8‐inch flexible mini‐LED display was fabricated using an indium–gallium–zinc oxide (IGZO) thin‐film transistor (TFT) backplane that adopted a top‐gate structure, with a pixel pitch of 0.55 mm and a resolution of 320 x 160, 46 PPI. With colorless polyimide (CPI) as the substrate, the mini‐LED panel has a thickness of less than 0.2 mm, and a transmittance is over 60%. The world's first 8‐inch, full‐color, flexible mini‐LED with IGZO‐TFT backplane is demonstrated.
