Abstract
A display panel and its driving method and driving device are provided for selectively reducing display resolution of a display panel, thereby decreasing display power consumption. The display panel comprises: gate lines (11) and data lines (12) disposed across to each other; at least one switching unit (13) connected between different gate lines (11), configured to control whether at least two rows of gate lines (11) are conducted; and a driving control module (14) having first output terminals (141) connected one by one to control terminals of the at least one switching unit (13) and second output terminals (142) connected one by one to input terminals of the data lines (12); wherein the driving control module (14) outputs, via the first output terminals (141), a control signal for controlling whether a corresponding switching unit (13) is switched on, and decides, based on an on/off state of the switching unit (13), whether to output an image signal to a corresponding data line (12) via the second output terminals (142).
