Abstract: In general, techniques are described for image modification for under-display sensors. A computing device comprising a display, one or more sensors positioned underneath the display, and one or more processors may be configured to perform various aspects of the techniques. The display may be configured to allow the one or more sensors to operate through the display. The one or more processors may be configured to determine an ambient light level, and modify, based on the ambient light level, an area of an image to obtain a modified image. The area of the image may correspond to pixels of the display positioned above the one or more sensors or correspond to pixels of the display that are not positioned above the one or more sensors. The one or more processors may then interface, with the display, to output the modified image.

Abstract: A system includes a microcontroller configured to: (a) receive, from an application processor, data for display on an organic light emitting diode (OLED) display having one region with a first dynamic range and another region having a second dynamic range; and (b) arrange the data into columns. A gamma generator is electrically connected to the microcontroller and generates first and second gammas specific to the different regions. A column driver is configured to: (a) apply the first gamma to each column to be displayed in the corresponding region to generate a first output, and apply the second gamma to each column to be displayed in the second region to generate a second output; and (b) electrically transmit the first and second outputs to the corresponding regions.
