Abstract:
A driving apparatus for a display device that is capable of lowering the manufacturing cost for different types of gate driving integrated circuits is presented. The apparatus has pixels arranged in a matrix, each pixel having a first and a second subpixels. A gate driver has a plurality of gate driving circuits, and each of the plurality of gate driving circuits generates first and second gate signals that are applied to the first and second subpixels, respectively. A controller outputs control signals for controlling the output of a carry signal for each of the gate driving circuits. Where an OR gate serves as the controller, two types of gate signals for different pixel rows can be generated: a first type where gate signals are applied to the different pixel rows at the same time and a second type where gate signals are not applied at the same time.
