Display device and method of controlling a gate driving circuit having two shift modes

摘要

A display device and a method of controlling a gate driving circuit thereof are discussed. The display device includes a display panel, first and second gate driving circuits which are respectively disposed on both sides of the display panel, and a timing controller. The timing controller controls the first and second gate driving circuits in conformity with a first shift mode, compares carry signals received from the first and second gate driving circuits, and controls the first and second gate driving circuits in conformity with a second shift mode when a time interval between the carry signals is greater than a previously determined reference value.

主权项

1. A display device comprising:
a display panel including data lines, gate lines crossing the data lines, and a pixel array; first and second gate driving circuits which are respectively disposed on both sides of the display panel with the pixel array interposed between them; and a timing controller configured to control a shift direction of the first and second gate driving circuits using a gate timing control signal, wherein the first and second gate driving circuits shift a gate pulse supplied to the gate lines along a first scan direction in a first shift mode and shift the gate pulse along a second scan direction opposite to the first scan direction in a second shift mode, and wherein the timing controller controls the first and second gate driving circuits in conformity with the first shift mode, compares carry signals received from the first and second gate driving circuits, and controls the first and second gate driving circuits in conformity with the second shift mode when a time interval between the carry signals is greater than a previously determined reference value.
