Patent ID: 10629147

Abstract:
Provided is a technique of causing less display irregularities to occur when the scanning of the gate lines is resumed in a display device in which the scanning of gate lines is performed intermittently.A display device includes a display panel, and a driving circuitry that includes a plurality of drive circuits for scanning gate lines. The driving circuitry alternately switches a scanning period in which the gate lines are scanned, and a non-scanning period in which the scanning of the gate lines is suspended, during one vertical scanning period, according to a control signal. Each driving circuit 301n includes a first switching element N that applies a selection voltage to the gate line; an internal line netA; a second switching element A that charges the internal line netA to a first potential; and a third switching element B that includes a drain electrode connected to the internal line netA, and a source electrode having a second potential that is lower than the first potential. a drive circuit corresponding one of the gate lines that is selected at start of the scanning period includes a charging circuit 301b(n) which recharges the internal line netA of this drive circuit to a potential equal to or higher than the first potential, before the start of this scanning period.
