Abstract
In an embodiment, an electronic display includes an active area including a plurality of pixels arranged in columns and a plurality of source drivers driving image data to columns of pixels. The electronic display also includes a first plurality of switches selectively coupling respective source drivers of the plurality of source drivers to one or more columns. Selective coupling enables the respective source drivers to, at different times, drive the image data to: a single column; and multiple columns. In another embodiment, an electronic display includes a display panel configured to operate using a reference voltage received via a resistive path having a routing resistance, a reference voltage source outputting the reference voltage, and a feedback circuit sensing an electrical parameter of the resistive path and producing a compensation voltage that, when added to the reference voltage, causes the reference voltage to remain substantially constant at the display panel.
