Abstract: A display apparatus sequentially outputs gate pulses to one side and the other side of gate lines. The display apparatus includes a display panel provided with four non-display areas outside a display area, a gate driver provided in a first non-display area of the non-display areas, a data driver provided in the first non-display area, and a controller for controlling the gate driver and the data driver. Gate lines connected to connection lines extended from the gate driver are provided in a second direction different from a first direction in which the connection lines are provided. Gate pulses supplied from the gate driver to the gate lines through the connection lines are alternately output from a first side and a second side of the gate lines. The first side and the second side are divided from each other based on a center portion of the gate lines as a boundary.

Abstract: A display device and a method of driving the display device are discussed. The display device includes a display panel which has subpixels disposed at points where data lines intersect gate lines. A data driver supplies a data voltage corresponding to specific input data to the data lines. An analog-to-digital converter (ADC) senses the data voltage supplied to at least one data line of the data lines, and converts the sensed data voltage to digital sensed data. A timing controller supplies compensation data compensated based on the digital sensed data to the data driver, thereby compensating for a deviation of the data driver.
