Abstract: An electronic device (200) includes a liquid crystal display (LCD) panel (204), a cover layer (218), one or more light sources (224), and an optical sensor module (226). The LCD panel (204) receives a contact input associated with a fingerprint of a user. The cover layer (218) includes a first major surface (228) and a second major surface (230) opposite to the first major surface (228), and is disposed on the LCD panel (204). The cover layer (218) defines a first axis (AA′) normal to the first major surface (228). The optical sensor module (226) receives a light from the predetermined fingerprint sensing area (222) to detect the fingerprint. The optical sensor module (226) at least partially overlaps with the predetermined fingerprint sensing area (222) along the plane of the first major surface (228). The optical sensor module (226) defines a second axis (BB′) normal to a surface of the optical sensor module (226). The second axis (BB′) is inclined at an inclination angle relative to the first axis (AA′) of the cover layer (218).

Abstract: Multi-layered solar cell devices covered with partially transmissive graphic films. The multi-layered solar cell devices include at least one solar cell, a graphics layer over the solar cell, and a reflective layer. The reflective layer can be behind the solar cell for recycling light or between the partially transmissive graphic film and the solar cell for improved appearance. The multi-layered solar cell devices have a high efficiency and a customizable appearance.
