TOUCH DISPLAY DEVICE, TOUCH DRIVING CIRCUIT AND METHOD FOR DRIVING TOUCH DRIVING CIRCUIT

摘要

The present embodiments relate to a touch display device, a touch driving circuit, and a driving method thereof. The level of converted digital data (no touch raw data) is checked based on a sensing signal received before the generation of a touch in a touch driving circuit. Logic for correcting the level of the no touch raw data is performed so that the level of the no touch raw data is included in the reference range of a predetermined baseline. Accordingly, it is possible to prevent the level deviation of the no touch raw data from affecting touch sensing based on the touch raw data and to increase the performance of the touch sensing.;COPYRIGHT KIPO 2018
