Problems solved by technology

Among them, the tri-state gate is usually composed of two P-type transistors and two N-type transistors, and the working state of the tri-state gate usually includes: high potential, low potential and high-impedance state. When the tri-state gate is in the high-impedance state, The potential of its output signal cannot usually be determined

[0004] In the process of realizing the present invention, the inventors found that the relevant technology has at least the following defects: the number of transistors in the tri-state gate is large, resulting in high power loss of the tri-state gate, which in turn leads to high power loss of the GOA unit, and Since the potential of the output signal of the tri-state gate is usually uncertain when it is in a high-impedance state, the GOA unit is prone to false output
