Abstract: In one aspect, a micro-LED display device includes a display panel with an array of a plurality of pixels, a first switch line, and a second switch line disposed in the display panel. Each of the plurality of pixels includes a micro-LED; a sub-pixel circuit configured to cause the micro-LED to emit light; and a Gate In Active (GIA) circuit configured to provide a scan signal to the sub-pixel circuit. The GIA circuit includes at least one gate driver configured to be enabled or disabled based on a first selection signal transmitted from the first switch line. The GIA circuit further includes at least one redundant gate driver configured to be enabled or disabled based on a second selection signal transmitted from the second switch line, wherein the redundant gate driver is enabled when the gate driver is disabled.
