Abstract: A gate driver includes a gate shift register in which an A block and a B block each having a plurality of stages, the A block and the B block being alternately arranged; scan clock lines inputting a first scan clock group and a second scan clock group each including both image data writing (IDW) scan clocks synchronized with an image write timing and black data insertion (BDI) scan clocks synchronized with a black write timing to the A block and the B block; and carry clock lines inputting carry clocks to the A block and the B block and sense clock lines inputting sense clocks to the A block and the B block, wherein each of the stages belonging to the A block and the B block includes a BDI memory storing a BDI carry signal for outputting the BDI scan clocks.

Abstract: Disclosed is a display apparatus with a simplified configuration. The display apparatus may include gate lines passing through a display area of a substrate, data lines passing through the display area of the substrate, pixel driving power lines passing through the display area of the substrate, a plurality of pixels having a pixel driving chip mounted on at least one pixel area defined on the substrate and connected and connected to an adjacent gate line and data line and a light emission part connected to the pixel driving chip, a gate driving chip array part mounted in a non-display area of the substrate and connected to the gate lines, and a data driving chip array part mounted in the non-display area of the substrate and connected to the data lines.
