| 20120320005 | DISPLAY APPARATUS AND A METHOD FOR DRIVING THE SAME - In a display apparatus, selection signals are supplied sequentially to scanning lines in each subframe period including a frame period for performing a display scan to write display data into pixel circuits. Selection signals are also supplied sequentially to scanning lines in at least two subframe periods including a frame period for performing an erase scan to write erase data into pixel circuits. There is an overlapping period between periods from a start to an end of the erase scan in the at least two subframe periods. During the overlapping period, selection signals for performing the erase scan are supplied simultaneously to the scanning lines. | 12-20-2012 |
| 20120320101 | DISPLAY APPARATUS - An exemplary embodiment of the present invention is a display apparatus. In the display apparatus, each row has as many row selection lines as the number of colors of light emitting elements, and row selection signals are supplied via the row selection lines such that a first row selection signal and a second row selection signals are supplied to driving circuits of light emitting elements of each color in first and second periods alternately and a plurality of times at different intervals in each frame. In the first period, light-emission or no-light-emission data signals are supplied over data lines. In the second period, only no-light-emission data signals are supplied. One of the first and second row selection signals is supplied with the same timing for all colors, while the other one of the row selection signals is supplied with timing different among the colors. | 12-20-2012 |
