Abstract

An optically enhanced diffuser panel (2600, 2700) is provided for a liquid crystal module (1720) integrated in an electronic device. Enhanced diffuser panels (2600, 2700) can be used for backlight enhancement and diffusion in electronic devices with integrated optical fingerprint sensors (1760). Enhanced diffuser panels (2600, 2700) include film layers (2620, 2660, 2720, 2760) that refract and diffuse light passing in one direction, eg, toward the display panel, while providing In the opposite direction, eg, towards the under-screen optical sensor (1760), the light passing through provides a transparent viewing window (2655). The film layers (2620, 2660) can provide backlight enhancement and diffusion without obscuring reflected probe light for optical sensing.

Description

[0001] Cross References to Related Applications [0002] This application claims the benefit of U.S. Nonprovisional Patent Application No. 16 / 535,092, filed August 8, 2019, and U.S. Provisional Application No. 62 / 877,692, filed July 23, 2019 , the contents of which are incorporated herein by reference in their entirety. technical field [0003] The present disclosure relates to liquid crystal displays, and more particularly, to brightness enhancement films and diffuser films for liquid crystal displays with under-display optical fingerprint sensors, for example, in display panel arrangements for mobile devices, wearable devices, and other computing devices Integrated optical fingerprint sensor. Background technique [0004] Various sensors can be implemented in an electronic device or system to provide certain desired functionality.
