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

A problem in this embodiment will be described here with reference to FIG. 4. FIG. 4 is a timing chart showing a comparative example of a driving method using the selection circuit 200. In one horizontal scanning period, image signals are supplied to nine pixels 110 arranged on one row among the plurality of pixels 110. In FIG. 4, “Vdata” represents the signal voltage of the image signal supplied to the signal line 124, and “SW1” to “SW9” represent the operation states of the switches SW configured to select the nine signal lines 124 and supply the image signals. Here, one horizontal scanning period can be a period from the start of the operation of supplying the signal voltage to one of the signal lines 124 first in one row (nth row) to the start of the operation of supplying the signal voltage to one of the signal lines 124 first in the next row ((n+1)th row).

In the driving method shown in FIG. 4, the switches SW1 to SW9 configured to select the signal lines 124 are sequentially turned on, and the corresponding signal lines 124 are selected. Accordingly, the signal voltages of the image signals are sequentially supplied to the corresponding signal lines 124. In one horizontal scanning period, the selection circuit 200 turns on each of the switches SW1 to SW9 once, selects each signal line once, and supplies the image signal.
