Abstract: An electronic device includes a display and a sensor underneath the display. The display has a full pixel density region and a reduced pixel density region. Compared to pixels in the full pixel density region, pixels in the reduced pixel density region can be controlled using overdriven power supply voltages, overdriven scan control signals, different initialization and reset voltages, and can include capacitors and transistors with different physical and electrical characteristics. Gate drivers provide scan signals to pixels in the full pixel density region, whereas overdrive buffers provide overdrive scan signals to pixels in the reduced pixel density region. The pixels in the full pixel density region and the pixels in the reduced pixel density region can be controlled using different black level or gamma settings for each color channel and can be adjusted physically to match luminance, color, as well as to mitigate differences in temperature and aging impact.
