Abstract:
The invention is a display panel with dot or column inversion capable of saving power, which uses shunt resistors composed of thin film transistors (TFTs) and an inverter to balance the positive and negative charge or reduce the difference between the positive and negative charge, thereby decreasing power consumption in the switch. The display panel with dot or column inversion capable of saving power includes: an inverter for electrically controlling the operating mode of a display panel; a first plurality of switches connected in series between the display panel and a data driver, to supply power from the data driver to pixels on the display panel; and a second plurality of switches connected in parallel between every two channels with the opposite polarities of the data driver outside the display panel, to construct an equivalent circuit loop according to the operation mode to be selected using the equivalent circuit loop, so as to reach the charge balance on every two channels with the opposite polarities powered by the data driver.
