US Patent 9679508 Display panel and repair method thereof

A display panel includes scan lines, data lines, organic light emitting diodes, pixel circuits configured to supply drive currents, and electrically coupled to the scan lines and the data lines, repair pixel circuits configured to generate repair drive currents when there is a malfunctioning pixel circuit, repair lines, and repair data lines, wherein a corresponding repair pixel circuit corresponds to the malfunctioning pixel circuit, and is configured to generate the repair drive current based on a repair data voltage from a corresponding repair data line, wherein the repair drive current is configured to be supplied to a corresponding organic light emitting diode that corresponds to the malfunctioning pixel circuit through a corresponding repair line that corresponds to the malfunctioning pixel circuit, and wherein a portion of the repair data lines that extends in the first direction is longer than a portion that does not extend in the first direction.
