Abstract:
A common data line serially connects a first dot memory group and a second dot memory group in layout order of driven devices so as to form each pair. First word lines are connected to the first dot memory group. Second word lines are connected to the second dot memory group. A data writing section supplies the correction values for the first dot memory group and the correction values for the second dot memory group while shifting the timing and supplies writing signals to the first word lines and the second word lines at predetermined timing. A chip area is reduced and costs of a driving apparatus is reduced.
