Claim Text:
1. A display driving circuit, comprising: 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, wherein the gate line shielding circuit comprises a first transistor, a second transistor, a first resistor, a second resistor and a third resistor, wherein, a gate of the first transistor functions as the first inputting terminal to receive the first output enable signal, a source of the first transistor is connected with a power supply and a drain of the first transistor is connected with one terminal of the first resistor; a gate of the second transistor functions as the second inputting terminal to receive the shielding signal, a source of the second transistor is connected with the power supply and a drain of the second transistor is connected with one terminal of the third resistor and functions as the outputting terminal; the other terminal of the first resistor is connected with one terminal of the second resistor and the other terminal of the third resistor; and the other terminal of the second resistor is grounded.
