Abstract
A selectable-repairing micro light emitting diode display is provided. A backplane includes a plurality of transistor units. A plurality of pixel units are disposed on the backplane, and each of the pixel units includes a plurality of original sub-pixel units and at least one selectable-repairing sub-pixel unit. Each of the original sub-pixel units includes a set of original pad. The set of original pad is disposed on the backplane and connected to one of the transistor units. The at least one selectable-repairing sub-pixel unit is arranged between two of the original sub-pixel units next to each other and having different colors, and includes a set of repairing pad. The set of repairing pad is not connected to the transistor units. A plurality of micro light emitting elements are electrically connected to the sets of original pad and controlled to emit light through the corresponding transistor units, respectively.
