Display With Localized Brightness Adjustment Capabilities - A simplified explanation of the abstract
This abstract first appeared for US patent application 18493576 titled 'Display With Localized Brightness Adjustment Capabilities
Simplified Explanation
The abstract describes an electronic device with a display that includes an array of pixels and an array of light sensors for capturing fingerprints through transparent windows in the display. Control circuitry in the device uses sensors to monitor for the presence of a user's finger over the light sensors, and directs the display to illuminate a subset of pixels to capture the fingerprint.
- Array of pixels in the display
- Array of light sensors for fingerprint capture
- Use of capacitive touch sensor, proximity sensor, force sensor, or other sensor
- Control circuitry to monitor user's finger presence
- Illumination of subset of pixels to capture fingerprint
- Display driver circuitry for momentary illumination with flash data

Original Abstract Submitted
An electronic device may have a display with an array of pixels. The device may have an array of components such as an array of light sensors for capturing fingerprints of a user through an array of corresponding transparent windows in the display. A capacitive touch sensor, proximity sensor, force sensor, or other sensor may be used by control circuitry in the device to monitor for the presence of a user's finger over the array of light sensors. In response, the control circuitry can direct the display to illuminate a subset of the pixels, thereby illuminating the user's finger and causing reflected light from the finger to illuminate the array of light sensors for a fingerprint capture operation. The display may have display driver circuitry that facilitates the momentary illumination of the subset of pixels with uniform flash data while image data is displayed in other portions of the display.
