Abstract:
1. A controller switching a display mode of a display panel, the display panel comprising a plurality of data electrodes and a plurality of gate electrodes divided into at least one first, second, and third gate electrode group, comprising: a processor providing a first initial signal and switching the display mode of the display panel to a first display mode when a select signal is asserted, wherein the processor provides a second initial signal to switch the display mode of the display panel to a second mode when the select signal is deasserted; a gate driver simultaneously activating the gate electrodes in the first gate electrode group when receiving the first initial signal, sequentially activating the gate electrodes in the second gate electrode group when the first gate electrode group is activated, and simultaneously activating the gate electrodes in the third gate electrode group when the second gate electrode group is activated; and a data driver providing corresponding image data to the data electrode depending on the activated gate electrodes when the first, second, or third gate electrode group is activated, wherein the gate driver sequentially activates the gate electrodes in the first gate electrode group when receiving the second initial signal, the gate driver sequentially activates the gate electrodes in the second gate electrode group when the first gate electrode group is activated, and the gate driver sequentially activates the gate electrodes in the third gate electrode group when the second gate electrode group is activated.
