The application discloses a GOA unit, a GOA circuit, a display device and a gate driving method. The GOA unit includes: a first input module, under the action of the first clock signal, aligns the first level signal with the first node voltage, and the first level signal is a low level signal; the second input module, the first Under the action of the clock signal, the voltage of the second node is aligned with the voltage of the input signal; the first output module, under the action of the first node, aligns the second level signal with the gate drive signal, and the second level signal is High-level signal; the second output module, under the action of the second node, aligns the voltage of the second node with the voltage of the second clock signal, further pulls the second node down, and the gate drive signal is a low-level signal; the second An energy storage module, used to maintain the voltage of the first node; a second energy storage module, used to maintain the voltage of the second node; an adjustment module, under the action of the first pulse signal of the second clock signal, level is aligned with the first node voltage.
Description
technical field [0001] The present disclosure generally relates to the field of display technology, and in particular, relates to a GOA unit, a GOA circuit, a display device, and a gate driving method. Background technique [0002] In recent years, the development of displays has shown a trend of high integration and low cost. One of the technologies is the realization of mass production of GOA (Gate Driver on Array, array substrate row drive). The GOA technology is used to integrate the gate switch circuit on the array substrate of the display panel, so that the part of the gate drive integrated circuit can be saved to reduce the cost in terms of materials and manufacturing process. Moreover, the display panel can achieve an aesthetic design with symmetrical sides and a narrow frame. The gate switch circuit integrated on the array substrate using the GOA technology is called a GOA circuit or a shift register circuit. [0003] The gate drive signal of most existing GOA ci...
