Abstract
A touchscreen display device includes: a display; a flexible printed circuit; touch sensing electrodes connected to the flexible printed circuit; and a multi-functional ambient light sensor package mounted on the flexible printed circuit. The multi-functional ambient light sensor package includes: an ambient light sensor; transmitter and receiver circuitry connected to the touch sensing electrodes via the flexible printed circuit; and a controller configured to obtain capacitance information from the touch sensing electrodes and ambient light information from the ambient light sensor via a single chip. The multi-functional ambient light sensor package may be packaged as a wafer-level chip-scale package (WLCSP).
