The conversion of kinetic energy into light emission can produce real‐time self‐powered luminescence. In this work, high‐intensity triboelectrification‐induced electroluminescence (TIEL) is obtained from microsized contacts that have relative sliding motion. The microsized structure significantly promotes the changing rate of the electric field within a luminescent layer. As a result, the produced luminescence intensity is enhanced by two folds compared with a plain‐surface contact. Besides, each microsized contact unit acts as a luminescence pixel. A collection of the contacts can be either designed into patterns or arranged into an array. Therefore, the high‐intensity TIEL presented can be potentially used in self‐powered display and illumination.
