An electronic device may include a display and an optical sensor formed underneath the display. A pixel removal region on the display may at least partially overlap with the sensor. The pixel removal region may include a plurality of non-pixel regions each of which is devoid of thin-film transistors. The plurality of non-pixel regions is configured to increase the transmittance of light through the display to the sensor. In addition to removing thin-film transistors in the pixel removal region, additional layers in the display stack-up may be removed. In particular, a cathode layer, polyimide layer, and/or substrate in the display stack-up may be patterned to have an opening in the pixel removal region. A polarizer may be bleached in the pixel removal region for additional transmittance gains. The cathode layer may be removed using laser ablation with a spot laser or blanket illumination.

A system may include an electronic display panel having pixels, where each pixel may emit light based on a respective programming signal. The system may include a memory storing a map. The processing circuitry may determine a function for each pixel from the map. The processing circuitry may determine a respective control signal based on the function and a target brightness level for each pixel to generate multiple control signals, where the respective control signal is used to generate the respective programing signal for each pixel. The processing circuitry may determine a scaling factor based at least in part on the first map and may scale at least a subset of the multiple control signals based at least in part on the scaling factor.

A method includes imaging a surface with at least one imaging sensor, wherein the surface and the imaging sensor are in relative translational motion. The imaging sensor includes a lens having a focal plane aligned at a non-zero angle with respect to an x-y plane of a surface coordinate system. A sequence of images of the surface is registered and stacked along a z direction of a camera coordinate system to form a volume. A sharpness of focus value is determined for each (x,y) location in the volume, wherein the (x,y) locations lie in a plane normal to the z direction of the camera coordinate system. Using the sharpness of focus values, a depth of maximum focus zalong the z direction in the camera coordinate system is determined for each (x,y) location in the volume, and based on the depths of maximum focus z, a three dimensional location of each point on the surface may be determined.
