Abstract: A touch display device and a light sensor module are discussed. The touch display device includes i light sensor modules, where i is a natural number greater than 1, for sensing a touch applied to a touch display panel, and a malfunction recovery unit for determining whether each of the i light sensor modules malfunctions and restarting at least one of the i light sensor modules when the at least one light sensor module is determined to malfunction.

Abstract: Disclosed herein is an apparatus and method for driving a touch sensor, which is capable of improving touch sensitivity and accuracy. The touch sensor driving apparatus includes a touch sensor; a read-out circuit; and a signal processor configured to compare raw data from the read-out circuit with a predetermined primary reference value and secondary reference value so as to determine whether the touch node has been touched, wherein the signal processor collects the raw data of each touch node or each channel during a plurality of frames and resets and updates the secondary reference value of each touch node or each channel using the collected raw data.
