SENSING DRIVING CIRCUIT AND DISPLAY DEVICE INCLUDING THE SAME

摘要

A sensing driving circuit and a display device including the same are disclosed. In one aspect, the sensing driving circuit includes a plurality of stages configured to respectively output a plurality of sensing signals and including a (K)th stage and a (K+1)th stage. The (K)th stage includes a shift register configured to provide a (K)th carry signal to the (K+1)th stage; and a masking buffer configured to output a (K)th sensing signal. The masking buffer includes a first input circuit configured to provide i) an input signal to a first node based on a node driving signal and ii) a first power voltage to a second node based on the input signal and the node driving signal. The masking buffer also includes a node masking circuit configured to supply the first power voltage to the first node based on a masking signal.
