Organic light emitting display and driving method thereof
An organic light emitting display and a driving method of the organic light emitting display capable of reducing or minimizing power consumption. The driving method includes setting a number of selection times constituting one frame, and setting a number of unit times constituting the one frame. Each of the unit times includes j (j is a natural number of 2 or more) of the selection times. Scan signals are non-sequentially supplied to scan lines during each of the unit times. The one frame includes a number of subframes. Data signals for ones of the subframes having a same length are supplied corresponding to i (i is a natural number of 2 or more) consecutive ones of the scan signals.
1. A method of driving an organic light emitting display, the method comprising:
setting a number of selection times constituting one frame; and
setting a number of unit times constituting the one frame, each of the unit times including j (j is a natural number of 2 or more) of the selection times,
wherein scan signals are non-sequentially supplied to scan lines during each of the unit times, the one frame comprises a number of subframes, and
wherein, in the one frame, for each one of the subframes, data signals for all ones of the subframes having a same length as each one of the subframes are supplied corresponding to consecutive ones of the scan signals supplied during i (i is a natural number of 2 or more) consecutive ones of the selection times.
2. The method of claim 1 , wherein data signals for ones of the subframes having two or more lengths are supplied during each of the unit times.
3. The method of claim 1 , wherein each of the selection times is a time when one of the scan signals is supplied to one of the scan lines.
4. The method of claim 1 , wherein the number of selection times constituting the one frame equals the number of subframes constituting the one frame times a number of the scan lines.
5. The method of claim 1 , wherein j is the number of subframes constituting the one frame.
6. The method of claim 5 , wherein i is smaller than j.
7. The method of claim 1 , wherein ones of the scan lines corresponding to the i consecutive ones of the scan signals are adjacent to each other.
8. The method of claim 1 , wherein ones of the scan lines corresponding to the i consecutive ones of the scan signals are spaced apart from each other by a number of the scan lines divided by i.
9. The method of claim 1 , wherein the subframes constituting the one frame have two or more lengths, and data signals for the subframes having all of the lengths are supplied during i consecutive ones of the unit times.
10. The method of claim 1 , wherein each of the data signals is a first data signal corresponding to emission of a pixel or a second data signal corresponding to non-emission of the pixel.
11. An organic light emitting display in which one frame includes j (j is a natural number of 2 or more) subframes, the organic light emitting display having unit times each including j selection times when scan signals are supplied, the organic light emitting display comprising:
pixels at crossing regions of scan lines and data lines;
a scan driver configured to non-sequentially supply the scan signals to the scan lines for each of the unit times; and
a data driver configured to supply, in the one frame, for each one of the subframes, data signals to the data lines for all ones of the subframes having a same length as each one of the subframes, corresponding to consecutive ones of the scan signals supplied during i (i is a natural number of 2 or more) consecutive ones of the selection times.
12. The organic light emitting display of claim 11 , wherein the data driver is further configured to supply data signals for ones of the subframes having two or more lengths during each of the unit times.
13. The organic light emitting display of claim 11 , wherein a number of the selection times constituting the one frame equals the number of the scan lines times j.
14. The organic light emitting display of claim 11 , wherein i is smaller than j.
15. The organic light emitting display of claim 11 , wherein ones of the scan lines corresponding to the i consecutive ones of the scan signals are adjacent to each other.
16. The organic light emitting display of claim 11 , wherein ones of the scan lines corresponding to the i consecutive ones of the scan signals are spaced apart from each other by a number of the scan lines divided by i.
17. The organic light emitting display of claim 11 , wherein each of the data signals is a first data signal corresponding to emission of one of the pixels or a second data signal corresponding to non-emission of the one of the pixels.
