Abstract
An electronic device may include a display. The display includes display driver circuitry for driving data lines routed across the display. The electronic device may have a recessed device housing region, where at least some of the data lines are routed around the recessed region. The data lines being routed around the recessed region may be formed in at least two different metal routing layers. The electronic device may further include additional display driver circuitry for driving data lines from another peripheral housing edge to obviate the need to route around the recessed region. The data lines from the two display driver circuitries can be disconnected at random locations or can be interlaced to achieve spatial interleaving. The display driver circuitry may include demultiplexing circuitry having smaller switches coupled in parallel with larger demultiplexer routing switches to reduce voltage kick and charge injection.
