Abstract
Embodiments relate to a touch sensing circuit, a touch display device, and a touch sensing method. The touch sensing circuit may comprise a touch sensing process configured to output a touch driving signal during a touch sensing period to at least two touch electrodes, and to convert a touch sensing signal detected through each touch electrode, to which the touch driving signal is applied, during an analog-to-digital conversion period, into a digital sensing value, and a communication processor configured to transmit sensing data including the digital sensing value converted during the analog-to-digital conversion period to a touch controller, wherein the communication processor starts transmission of the sensing data including converted digital sensing values of at least some of touch sensing signals before each of touch sensing signals detected from the at least two touch electrodes are converted into a digital sensing value. The present invention enables quick touch sensing. In addition, noise generated in the touch information detection process can be reduced and the signal-to-noise ratio can be improved so that the touch sensitivity can be improved.
