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

In the driving method shown in FIG. 8, the pixel groups to supply the image signals are selected in order such that the medians in the ranges of the signal voltages of the image signals are small, medium, and large in terms of the magnitude relationship. However, the medians may be large, medium, and small in terms of the magnitude relationship. The selection circuit 200 appropriately selects the pixel groups in order in accordance with the magnitude relationship of the medians in the ranges of the signal voltages of the image signals. Additionally, in the above description, the medians in the ranges of the signal voltages of the image signals become large in the order of red, blue, and green. However, if the magnitude relationship of the medians in the ranges of the signal voltages changes depending on the emission efficiency of each color, or the like, the order of the pixel groups to supply the image signals may appropriately be changed.
