Description

technical field [0001] The present invention relates to the field of display technology, in particular to a gate drive unit, a gate drive method, a gate drive circuit and a display device. Background technique [0002] In related gate drive units applied to LTPO (low temperature polycrystalline oxide) pixel circuits, generally the P-type transistor outputs the gate drive signal required by the P-type transistor, and then the N-type transistor is obtained through the inverter. For the required gate driving signal, the number of transistors required to be used in the related gate driving unit applied to the LTPO pixel circuit is large. Contents of the invention [0003] The main purpose of the present invention is to provide a gate drive unit, a gate drive method, a gate drive circuit and a display device, which solve the problem of providing an N-type transistor in an LTPO (low temperature polycrystalline oxide) pixel circuit in the prior art. When the polar drive signal i...
