Abstract
An example device includes a display panel; a fingerprint sensor configured to sense a fingerprint through the display panel; and processing circuitry configured to: responsive to activation of the fingerprint sensor: activate a local high brightness mode by at least increasing an amount of light radiated from a first portion of the display panel that overlies the fingerprint sensor; and temporarily decrease controlled brightness of a second portion of the display panel that is non-overlapping with the first portion.
Claims19
A device comprising:
- a display panel;
- a fingerprint sensor configured to sense a fingerprint through the display panel;
- and
- processing circuitry configured to:
- responsive to activation of the fingerprint sensor:
- activate a local high brightness mode by at least increasing an amount of light radiated from a first portion of the display panel that overlies the fingerprint sensor;
- and
- temporarily decrease controlled brightness of a second portion of the display panel that is non-overlapping with the first portion.
A method comprising:
- responsive to activation of a fingerprint sensor that is configured to sense a fingerprint through a display panel:
- activating a local high brightness mode by at least increasing an amount of light radiated from a first portion of the display panel that overlies the fingerprint sensor;
- and
- temporarily decreasing controlled brightness of a second portion of the display panel that is non-overlapping with the first portion.
A non-transitory computer-readable storage medium storing instructions that, when executed by a controller of a device, cause the controller to:
- responsive to activation of a fingerprint sensor of the device that is configured to sense a fingerprint through a display panel of the device:
- activate a local high brightness mode by at least increasing an amount of light radiated from a first portion of the display panel that overlies the fingerprint sensor;
- and
- temporarily decrease controlled brightness of a second portion of the display panel that is non-overlapping with the first portion.
