Display panel with inactive region used in a head mounted display
An electronic display includes a display panel that operates in a single display mode to provide a single display, or a dual display mode to provide two displays separated by an inactive region. The electronic display includes the display panel and a panel driver. The display panel includes a left pixel region, a right pixel region, and a middle pixel region between the left and right pixel regions. In the single display mode of the electronic display, the panel driver provides first gate signals generated from first input data to the left, right, and middle pixel regions. In a dual display mode, the panel driver provides second gate signals generated from second input data to the left and right pixel regions. The first input data has a first resolution that is larger than a second resolution of the second input data.
