    Abstract: A display apparatus includes a display panel, a first driver and a second driver. The display panel includes a plurality of gate lines and a plurality of data lines. The display panel is configured to display an image based on input image data. The first driver is configured to output compensating gate signals having the same timing to the gate lines during a first period and scan gate signals having different timings to the gate lines during a second period. The second driver is configured to apply a compensating data voltage corresponding to a compensating grayscale value to the data lines during the first period and a target data voltage corresponding to a target grayscale value to the data lines during the second period.

    Abstract: A display apparatus includes a display panel, a gate driving part, and a data driving part. The display panel is configured to display an image, and includes a gate line and a data line. The gate driving part is configured to output a gate signal to the gate line. The data driving part is configured to output a data signal to the data line. A transition time of the data signal is a time when the data signal transitions from a low level to a high level, and the transition time of the data signal increases according to a decrease of a load of the display panel.

    Abstract: A display device includes a display panel including data lines, gate lines, and pixels connected to the data lines and the gate lines, a data driver configured to drive the data lines, a plurality of gate drivers, each configured to drive a corresponding portion of the gate lines, and a plurality of feedback lines connected to one of the data lines at a plurality of measurement positions corresponding to the plurality of gate drivers. The data driver applies a test voltage to the data line, receives the test voltage as a plurality of feedback voltages through the plurality of feedback lines, and determines gate shift amounts at the plurality of measurement positions corresponding to the plurality of gate drivers based on the plurality of feedback voltages. The gate drivers apply gate signals to the gate lines that are shifted by the determined gate shift amounts.

    Abstract: A display device includes a first interconnection line, a first data driver, a second interconnection line, an electrostatic discharge (ESD) circuit, and a display panel. The first connection line transmits a data driving signal. The first data driver includes the first interconnection line and output a data signal based on the data driving signal. The second interconnection line passes through the first data driver and transmits a gate driving signal. The ESD) circuit in the first data driver and discharges static electricity transmitted through the second interconnection line. The first gate driver outputs a gate signal based on the gate driving signal transmitted through the second interconnection line. The display panel receives the data signal and the gate signal.
