Abstract
A touch control circuit for use in a display device includes: a plurality of analog-to-digital converters and a controller. Each of the analog-to-digital converters is coupled to at least one of a plurality of touch sensing electrodes and at least one of a plurality of source drivers of the display device. At least one of the analog-to-digital converters is configured to generate a first measured digital code according to an output voltage outputted by at the least one of the source drivers. The controller is coupled to the analog-to-digital converters, and configured to compare the first measured digital code with an input digital code that the output voltage of the at the least one of the source drivers corresponds to, thereby to generate a first safety detection result regarding the at least one of the source drivers.
