DISPLAY DEVICE INCLUDING PAD FOR MEASURING GATE PULSE AND GATE PULSE MEASURE METHOD USING THE PAD

摘要

The present invention relates to a display apparatus including a gate pulse measurement pad and a gate pulse measurement method using the pad. A display device including a pad for gate pulse measurement according to the present invention includes: a display panel including a pixel array including data lines and gate lines intersecting with each other and pixels arranged in a matrix; A first gate driving circuit arranged on a first side of the display panel for sequentially supplying gate pulses to one end of the gate lines; A second gate driving circuit arranged at a second side corresponding to the first side and sequentially supplying the gate pulse to the other end of the gate lines; A data driving circuit for supplying a data voltage to the data lines; And a gate pulse measurement pad connected to one of a gate line disposed at the top of the gate lines and a gate line disposed at the lowermost position to measure a delay time of the gate pulse supplied to the gate line, , And the operation timings of the second gate driving circuit and the first gate driving circuit are synchronized.
