Abstract
A multiplexer circuit includes a first switch unit and a second switch unit. The first switch unit is electrically connected to a first data line and a first pixel circuit, and configured to turn on according to a first signal in a first time duration. The second switch unit is electrically connected to the first data line and a second pixel circuit, and configured to turn on according to a second signal in a second time duration. The first time duration and the second time duration substantially start or end at a same time, so that the first time duration and the second time duration have overlap.
