CROSS-REFERENCE TO RELATED APPLICATION 
     This application claims priority of the Chinese patent application No. 202010908595.6 filed on Sep. 2, 2020, which is incorporated herein by reference in its entirety. 
     TECHNICAL FIELD 
     The present disclosure relates to the field of display technology, and more particularly to a gate driving unit, a driving method, a gate driving circuit and a display device. 
     BACKGROUND 
     In order to keep the brightness fluctuation of pixels within a reasonable range, the data still needs to be refreshed for a still picture, because the voltage that controls the brightness changes over time due to leakage. In order to reduce power consumption, reducing the refresh frequency is a more effective method. At the same time, it is necessary to maintain the display quality, and it is necessary to reduce the leakage speed of pixels. Oxide semiconductors have ultra-low leakage characteristics to meet this demand. In order to ensure the charging speed of the pixel and small parasitic capacitance, it is beneficial to combine the Low Temperature Polycrystalline Oxide (LTPO) process. When the existing gate driving unit is in operation, the potential of the gate driving signal cannot be prevented from being affected by noise interference in a maintenance phase.
