Display driving circuit and driving method thereof, display apparatus

摘要

The present disclosure relates to the display technique. Disclosed is a display driving circuit, including: a gate line driving circuit, configured to separate gate line driving signals of adjacent rows according to a first output enable signal; a shielding signal generation circuit, configured to trigger and generate a shielding signal when the gate line driving signal needs to be turned off; and a gate line shielding circuit configured to shield the first output enable signal according to the shielding signal so as to turn off the gate line driving signal, wherein the first output enable signal is inputted from a first inputting terminal of the gate line shielding circuit, the shielding signal is inputted from a second inputting terminal of the gate line shielding circuit, and an outputting terminal of the gate line shielding circuit is connected to the gate line driving circuit. The display driving circuit, a driving method thereof and a display apparatus according to the embodiments of the present disclosure are capable of shielding the first output enable signal directly according to the shielding signal so as to turn off the gate line driving signal and shield the data on the corresponding gate lines, thereby they can avoid occurring of abnormal statuses with the first output enable signal and also can save the cost and space of the circuit.
