摘要

A display apparatus in which selection circuits and display blocks are arranged is provided. Each of the display blocks include signal lines extending in a column direction, and pixels connected to the signal lines and arranged in a matrix in the column direction and in a row direction crossing the column direction. Each of the selection circuits selects a signal line in a predetermined order to supply an image signal among the signal lines such that the image signal is written in each of the pixels arranged in the row direction among the pixels. A time to select at least one signal line among the signal lines and supply the image signal is different from a time to select a signal line other than the at least one signal line among the signal lines and supply the image signal.

說明書

When the driving method shown in FIG. 5 is used, it is possible to suppress an error in the signal voltage of the image signal caused by the shortage of time to select the signal line 124 when supplying the image signal and cause each pixel 110 to emit light at a more correct luminance on the display apparatus 100. In addition, when supplying the image signals continuously to the pixels 110 of the same emission color, the time to select the corresponding signal line 124 by the switching unit 203 is made shorter than that when supplying the image signals continuously to the pixels 110 of different emission colors. This can suppress lowering of the frame rate when displaying an image.
