Abstract
A display device including a surface for viewing an image comprising a stack of layers configured to display the image. A processor is configured to include switchable detection modes. Each mode is preconfigured to detect an object on or near the surface based on a given sensitivity to light, and has a different sensitivity than other of the modes.

2. A device, comprising:
-
a stack of layers having a surface and being configured to display an image, multiple light sensitive elements included in the stack of layers, and a processor configured to selectively operate in any one of multiple detection modes in which the processor detects an object on or near the surface in response to light based on a preconfigured sensitivity to light associated with the light sensitive elements, wherein the preconfigured sensitivity to light according to which the processor detects an object when operating in one of the detection modes differs from the preconfigured sensitivity to light according to which the processor detects an object when operating in other of the detection modes, the multiple light sensitive elements being configured to generate data indicative of a fingerprint when a finger is on or near the surface of the stack of layers, and the processor being configured to identify the fingerprint based on the data from the multiple light sensitive elements. - View Dependent Claims (3, 4, 5, 6, 7, 8, 9, 10, 11, 12, 13, 14, 15, 16, 17, 18)

19. A method, comprising:
-
switching, via a device comprising a stack of layers that includes multiple light sensitive elements, has a surface and is configured to display an image at the surface of the stack of layers, between any one of multiple detection modes in which the device detects an object on or near the surface in response to light based on a preconfigured sensitivity to light associated with the light sensitive elements, the preconfigured sensitivity to light according to which the device detects an object when operating in one of the detection modes differing from the preconfigured sensitivity to light according to which the processor detects an object when operating in other of the detection modes, generating, via the multiple light sensitive elements, data indicative of a fingerprint when a finger is on or near the surface of the stack of layers, and identifying the fingerprint based on data generated via the multiple light sensitive elements. - View Dependent Claims (20, 21, 22, 23)
