Abstract
A liquid crystal display (LCD) assembly and an electronic device are provided. The LCD assembly includes: a touch screen, an upper substrate disposed parallel to the touch screen, a lower substrate disposed parallel to the upper substrate, a liquid crystal layer enclosed between the upper substrate and the lower substrate, an upper polarizer attached to a side of the upper substrate not adjacent to the liquid crystal layer, and a lower polarizer attached to a side of the lower substrate not adjacent to the liquid crystal layer. At least one fingerprint identification sensor is disposed between the upper polarizer and the lower polarizer, and each of the fingerprint identification sensors is electrically connected to the control chip. At least one light sensor is disposed between the upper polarizer and the lower polarizer, and each of the least one light sensor is electrically connected to the control chip.
