摘要： A display apparatus includes a display panel including gate and data lines disposed thereon, and a plurality of driver integrated circuits (“ICs”) on the display panel and electrically connected to data lines. Flexible printed circuit boards (“FPCBs”) are disposed on the display panel and a printed circuit board to apply the control signal and the image signal from the printed circuit board to the driver ICs. There are less FPCBs than driver ICs. The driver ICs are divided into first and second driver groups; the data lines are divided into first and second groups of data lines. Driver ICs of the first driver group are directly connected to corresponding FPCBs, and driver ICs of the second driver group are connected to adjacent driver ICs. Each driver integrated circuit of the first driver group outputs a first repair signal to repair a data line of the first group of data lines.

摘要： A gate driver circuit includes a driving section and a wiring section. The wiring section receives a plurality of signals from an external device. The driving section includes a plurality of stages providing a plurality of gate lines with a gate signal. The wiring section includes first and second signal wirings. The first signal wiring is disposed adjacent to a first side of the driving section, where the first side receives the signals from the wiring section. The second signal wiring is disposed adjacent to a portion that is disposed at an outer side of the driving section and the first signal wiring. Therefore, a signal applied to the first signal wiring is prevented from being delayed by the second signal wiring. Furthermore, a distortion of signal applied to the gate driver and a maloperation of the gate driver are prevented.

摘要： A display substrate includes source lines, gate lines, an output pad part, a fan-out part and a first voltage line part. The source lines are in a display area. The gate lines cross the source lines. The output pad part is in a peripheral area surrounding the display area and is electrically connected to output terminals of a driving chip. The fan-out part is electrically connected between the output pad part and the source lines. The first voltage line part is inclined with respect to a central line of a chip area in which the driving chip is mounted toward opposite sides of the chip area to cross the fan-out part. Therefore, the line reactance of the fan-out part is decreased and the uniformity of the line resistance of the fan-out part is increased to improve image display quality.
