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).

Abstract: A controller for a sensor is configured to receive a control signal from an external device, the control signal corresponding to potential interference. The controller adjusts a sensing parameter using the control signal to avoid the potential interference. The potential interference is at least one of an electrical interference and an optical interference. The controller may include a sensor module that includes circuitry configured to acquire resulting signals with sensing elements using the adjusted sensing parameter.
