Abstract
A display device and a method of driving the same. The display device includes a display panel on which a plurality of data lines and a plurality of gate lines intersect each other to form a matrix, with a number of pixels being defined at intersections of the plurality of data lines and the plurality of gate lines. A data driver is connected to the plurality of data lines. A gate driver is connected to the plurality of gate lines. A timing controller controls the display panel to operate in a driving mode that changes depending on image signals.
Claims20
A display device comprising:
- a display panel on which a plurality of data lines and a plurality of gate lines intersect each other to form a matrix, with a number of pixels being defined at intersections of the plurality of data lines and the plurality of gate lines;
- a data driver connected to the plurality of data lines;
- a gate driver connected to the plurality of gate lines;
- and
- a timing controller which controls the display panel to operate in a driving mode that changes depending on image signals.
A method of driving a display device, comprising:
- receiving image signals of a predetermined frame;
- calculating a difference in data value between the image signals of the predetermined frame or levels of complexity of the image signals of adjacent frames;
- and
- controlling a display panel to operate in a driving mode selected from the group consisting of dot inversion, a column inversion and frame inversion depending on the difference in the data value between the image signals of the predetermined frame or the levels of complexity of the image signals of the predetermined frame.
A display device comprising:
- a display panel on which a plurality of data lines and a plurality of gate lines intersect each other to form a matrix, with a number of pixels being defined at intersections of the plurality of data lines and the plurality of gate lines;
- a data driver connected to the plurality of data lines;
- a memory storing an image signal of a first drive frequency input from a host system;
- and
- a timing controller that controls the display panel to be driven with an image signal of a second drive frequency obtained from the image signal stored in the memory by data multiplying, the second drive frequency being m times the first drive frequency, where m is a real number greater than 1.
