Abstract
A display device includes a plurality of gate lines, at least one data line, and a plurality of pixels connected to the plurality of gate lines and the at least one data line. The display device is configured to perform a first step of sequentially selecting N lines of the plurality of gate lines, and sequentially outputting N times display signals to the data line, and to perform a second step of selecting Z lines of the plurality of gate lines at one time, and outputting one time a blanking signal, where N and Z are natural numbers at least equal to 2. The Z lines are separate from the N lines, and the first step and the second step are repeatedly performed.
Claims18
A display device comprising:
- a plurality of gate lines;
- at least one a data line;
- and
- a plurality of pixels connected to the plurality of gate lines and the at least one data line;
- wherein the display device is configured to enable a first step of sequentially selecting N lines of the plurality of gate lines, and sequentially outputting N times display signals to the at least one data line, where N is a natural number of at least 2;
- wherein the display device is configured to enable a second step of selecting Z lines of the plurality of gate lines at one time, and outputting one time a blanking signal, where Z is a natural number of at least 2;
- wherein the Z lines are separate from the N lines, and the first step and second step are repeated;
- and
- wherein a display signal polarity of the blanking signal is different from a display signal polarity of a first outputted display signal of the beginning time of the N times of the next first step.
A display device comprising:
- a plurality of gate lines;
- at least one a data line;
- and
- a plurality of pixels connected to the plurality of gate lines and the at least one data line;
- wherein the display device is configured to enable a first step of sequentially selecting N lines of the plurality of gate lines, and sequentially outputting N times display signals to the at least one data line, where N is a natural number of at least 2;
- wherein the display device is configured to enable a second step of selecting Z lines of the plurality of gate lines at one time, and outputting one time a blanking signal, where Z is a natural number of at least 2;
- wherein the display device comprises a normally black display portion;
- wherein the Z lines are separate from the N lines, and the first step and second step are repeated;
- and
- wherein a display signal polarity of the blanking signal is different from a display signal polarity of a first outputted display signal of the beginning time of the N times of the next first step.
