Abstract: A display panel includes a plurality of array sites arranged in an array defined by a plurality of rows and a plurality of columns. The display panel includes a first area of the array having a first pixel density and a second area of the array having a second pixel density lower than the first pixel density. The second area of the array includes a plurality of the array sites that are devoid of pixels. Rows of the second area that border the first area include at least one pixel and columns of the second area that border the first area include at least one pixel.

Abstract: Rendering images on an active area of an OLED includes rendering images on the active area of the display panel with a plurality of different frame rates. For a plurality of the different frame rates having a frame rate that matches or is above a threshold frame rate, an image refresh operation is performed once per frame period and a self-refresh operation is not performed during the frame period. When rendering images on the active area, for at least one of the different frame rates having a frame rate that is lower than the threshold frame rate, an image refresh operation is performed once per frame period and a self-refresh operation is performed at least once during the frame period.

Abstract: A method includes displaying an image on an organic light-emitting (OLED) display panel that includes a first display area having a first pixel density and a second display area having a second pixel density lower than the first pixel density, and while displaying the image, deactivating individual pixels in the first display area corresponding to a proximity of the individual pixels to the second display area such that a region of the first display area adjacent the second display area has a virtual pixel density between the first pixel density and the second pixel density.
