Abstract

The invention discloses a GOA circuit and a driving method thereof as well as a display device, and belongs to the technical field of display. The GOA circuit comprises a plurality of stages of GOA unit groups which are arranged in series, wherein each GOA unit group comprises at least one stage of GOA units which are arranged in series; the GOA circuit further comprises a control unit; the control unit is connected with the first stage of GOA unit in each GOA unit group, and is used for inputting frame initial signals to the first stage of GOA unit in the first stage of GOA unit group in a display area. The GOA circuit can effectively reduce the power consumption of display device products.

Description

technical field [0001] The invention relates to the field of display technology, in particular to a GOA circuit and a driving method thereof, a display panel and a display device. Background technique [0002] With the continuous development of display technology, people not only have strict requirements on the appearance and quality of display products, but also pay more attention to the price and practicality of display products. In order to meet the needs of users, technologies such as integrating scanning drive circuits or bilateral drive circuits on glass substrates have emerged as the times require. Such a technology can not only greatly improve the production yield of display products, but also significantly reduce the price of display products. , so as to meet the user's requirements for product quality and price. One of the very important technologies is the realization of mass production of GOA (Gate Driver on Array, array substrate row drive) technology. Using G...
