Displays that Overlap Light Sensors

The abstract describes an electronic device with a display and an optical sensor underneath it. The device includes a locally modified region that overlaps the optical sensor to mitigate diffractive artifacts that could affect the sensor's performance. Various techniques such as spatial randomization, opaque structures, black masking layers, apodization, and phase randomization film are used in the locally modified region to reduce diffraction artifacts.

Spatial randomization, opaque structures, black masking layers, apodization, and phase randomization film are used in the locally modified region of the display to mitigate diffractive artifacts.
The modification in the locally modified region helps in reducing the impact of diffractive artifacts on the optical sensor.
Circular footprints of opaque structures and circular openings in the black masking layer are utilized to improve the performance of the optical sensor.
The use of apodization and phase randomization film further enhances the mitigation of diffractive artifacts in the electronic device.

Potential Applications: - This technology can be applied in smartphones, tablets, laptops, and other electronic devices with displays and optical sensors. - It can improve the accuracy and reliability of optical sensors used for various functions such as ambient light sensing, proximity sensing, and gesture recognition.

Problems Solved: - Mitigates diffractive artifacts that could impact the performance of optical sensors in electronic devices. - Enhances the overall functionality and efficiency of optical sensors in devices with displays.

Benefits: - Improved accuracy and reliability of optical sensors. - Enhanced performance of electronic devices with displays. - Reduction of interference from diffractive artifacts.

Commercial Applications: - Smartphone manufacturers can integrate this technology to improve the functionality of ambient light sensors and proximity sensors. - Tablet and laptop manufacturers can utilize this innovation to enhance gesture recognition capabilities in their devices.

Questions about the technology: 1. How does the use of spatial randomization help in reducing diffractive artifacts in the optical sensor? 2. What are the specific benefits of incorporating apodization in the locally modified region of the display?

Original Abstract Submitted

an electronic device may include a display and an optical sensor formed underneath the display. the electronic device may include a locally modified region that overlaps the optical sensor. the locally modified region of the display may have a modification relative to a normal region of the display that does not overlap the optical sensor. the modification may mitigate diffractive artifacts that would otherwise impact the optical sensor that senses light passing through the display. to mitigate diffraction artifacts, the locally modified region of the display may use spatial randomization (e.g., spatial randomization of signal paths and/or spatial randomization of via locations), opaque structures may be formed with circular footprints, a black masking layer may be formed with circular openings, apodization may be used, and/or a phase randomization film may be included.
