Abstract
A scanning method of a display of the present invention changes a driving order of a plurality of gate driver lines according to a frame data so as to reduce switching currents generated while a plurality of voltages on a plurality of source driver lines are changed. Thereby, the goal of saving power can be reached.
Claims5
A scanning method of a display including a plurality of gate driver lines and a plurality of source driver lines, the scanning method comprising steps of:
- A.) saving a frame data in a frame buffer;
- B.) selecting one of the gate driver lines according to the saved frame data to obtain a first gate driver line that is to be firstly driven;
- C.) selecting another gate driver line from the gate driver lines that are not selected according to the saved frame data to obtain a second gate driver line that is to be secondly driven, such the second gate driver line allowing a plurality of voltages on the source driver lines to be changed the least;
- and
- D.) judging if there are any the gate driver lines that are not selected, executing the step C again if the judgment is yes, ending up if the judgment is no.
2 more elements
A display comprising:
- a plurality of gate driver lines, being driven by a first driving order when the display displays a first frame data, and driven by a second driving order different from the first driving order when the display displays a second frame data;
- and
- a plurality of source driver lines;
- wherein a first image displayed by the display according to the first frame data has a first number of times for color changing on a direction of the source driver lines, a second image displayed by the display according to the second frame data has a second number of times for color changing on the direction of the source driver lines, and the first number is less than the second number, and
- wherein the first frame data is directed to a color block image, and the second frame data is directed to a stripe image.
