  • Patent number: 8243002
    Abstract: In a display device, a first frame of input image signals is received by a signal controller, stored in a memory, and applied to rows of pixels while a gate driver scans a gate-on voltage to a gate line in a first mode to select a row of pixels, one row at a time. When a gate driver controller detects that a second frame of image signals is being received by the signal controller, the gate driver controller halts the operation of the gate driver until the second frame of input image signals has all been received by the signal controller and until a scan start signal is detected by the gate driver controller.

    Abstract: A driving apparatus for a display device and display device having the driving apparatus. The display device has a plurality of pixels each having a switching element. The driving apparatus includes a gate line connected to the switching element, a gate driver to apply a gate signal having first to third voltages to the gate line, a first voltage generator to generate the first and third voltages, and a second voltage generator to generate the second voltage. The first and second voltages turn on the switching element, and the third voltage turns off the switching element. The second voltage is less than the first voltage. Thus, since the gate driver includes the second voltage generator to generate the second voltage and a plurality of transistors, and generates a gate output having a step shape, a kickback voltage is reduced and flicker is prevented.
