DISPLAY DEVICE AND DRIVING METHOD THEREOF
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.
1 . A display device comprising:
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,
wherein the display device is operated in a normally black displaying mode, and
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 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.
2 . A display device according to claim 1 , wherein the number N and the number Z are the same.
3 . A display device according to claim 2 , wherein the number N and the number Z are set to 4.
4 . A display device according to claim 1 , wherein the number N is set to 4.
5 . A display device according to claim 1 , wherein the display signal polarity of the blanking signal of the second step is the same as a display signal polarity of a last display signal of the N times of previous first step.
6 . A display device according to claim 5 , wherein the number N and the number Z are same.
7 . A display device according to claim 6 , wherein the number N and the number Z are set to 4.
8 . A display device according to claim 5 , wherein the Number N is set to 4.
9 . A display device according to claim 1 , wherein a gate line selected at a last time and receiving a last display signal of the N times in a first frame is different from a pixel receiving a last display signal of the N times in a second frame.
10 . A display device comprising:
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,
wherein the display device is operated in a normally black displaying mode, and
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.
11 . A display device according to claim 10 , wherein the number N and the number Z are the same.
12 . A display device according to claim 11 , wherein the number N and the number Z are set to 4.
13 . A display device according to claim 10 , wherein the number N is set to 4.
14 . A display device according to claim 10 , wherein the display signal polarity of the blanking signal of the second step is the same as a display signal polarity of a last display signal of the N times of previous first step.
15 . A display device according to claim 14 , wherein the number N and the number Z are the same.
16 . A display device according to claim 15 , wherein the number N and the number Z are set to 4.
17 . A display device according to claim 14 , wherein the number N is set to 4.
18 . A display device according to claim 10 , wherein a gate line selected at a last time and receiving a last display signal of the N times in a first frame is different from a pixel receiving a last display signal of the N times in a second frame.
