In this letter, a dual-polarized dual-band antenna-on-display (AoD) is proposed for millimeter-wave (mmWave) wireless scenarios. The proposed AoD schematic supports patch and monopole mode based on a shared aperture and antenna feed network concept. The devised AoD exhibits dual resonance with $ - $10 dB S11 bandwidth of 26–31 GHz (17.8%) and 33–40.5 GHz (19%). Based on the proposed unit element, a 1 × 4 phased array AoD is exemplified to verify its beam steering capability. The measured beam scanning angles demonstrate $ \pm $40$^\circ $ at 28 GHz and $ \pm $ 37$^\circ $ at 38 GHz with ±45$^\circ $ polarization. The proposed work is the first to realize multipolarized, multiband AoD under realistic conditions. This letter aims to suggest a principal example for future multiband mmWave wireless scenarios using display panel as antennas.
