Display device with a power saving mode in which operation of either the odd-line gate driver or the even-line gate driver is halted

A display device comprising:

• an insulation substrate;
• a plurality of gate lines on the insulation substrate and divided into a first group and a second group;
• a plurality of data lines insulated from and intersecting the plurality of gate lines;
• a gate driver which applies a gate-on voltage to the plurality of gate lines and operates in one of a first mode and a second mode;
• and
• a data driver which applies a data voltage to the plurality of data lines,
• wherein the first group and the second group of the plurality of gate lines are applied with the gate-on voltage when the gate driver is in the first mode, and
• wherein the first group of the plurality of gate lines is applied with the gate-on voltage each frame and the second group of the plurality of gate lines is in an off state for the entire duration of at least two consecutive frames when the gate driver is in the second mode,
• wherein
• the first group of the plurality of gate lines is one of an odd-numbered gate line group and an even-numbered gate line group,
• the second group of the plurality of gate lines is the other of the odd-numbered gate line group and the even-numbered gate line group,
• and all of the odd-numbered gates lines are in the odd-numbered gate line group and all of the even-numbered gate lines are in the even-numbered gate line group.
