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 (500A-K) includes a plurality of stages configured to respectively output a plurality of sensing signals (SEN[k]) and including a (K)th stage and a (K+1)th stage. The (K)th stage includes a shift register (600A-k) configured to provide a (K)th carry signal to the (K+1)th stage; and a masking buffer (700A-k) configured to output a (K)th sensing signal. The masking buffer includes a first input circuit (710) configured to provide i) an input signal (CARRY[k-1]; SSP) to a first node (N1) based on a node driving signal (SET) and ii) a first power voltage (VGH) to a second node (N2) based on the input signal (CARRY[k-1]; SSP) and the node driving signal (SET). The masking buffer also includes a node masking circuit (740) configured to supply the first power voltage (VGH) to the first node (N1) based on a masking signal (MASK). |
