Title:
ASYMMETRIC BRIGHTNESS ENHANCEMENT FILMS FOR LIQUID CRYSTAL DISPLAY ASSEMBLIES
Document Type and Number:
WIPO Patent Application WO/2021/012702
Kind Code:
A1
Abstract:
Optical enhancement and diffuser panels (2600,2700)are provided for liquid crystal modules (1720) integrated in electronic devices (200). The enhancement and diffuser panels (2600,2700)can be for backlight enhancement and diffusing in electronic devices (200) having an integrated optical fingerprint sensor (181). The enhancement and diffuser panels (2600,2700) include film layers (3020,3060)that refract and diffuse light passing through in one direction (e.g., toward a display panel (433)), while providing clear viewing windows (2655) for light passing through in the opposite direction (e.g., toward an under-display optical sensor). For example, the film layers (3020,3060) can provide backlight enhancement and diffusing, without blurring reflected probe light used for optical sensing.
