The invention provides a gate driving circuit, a display panel, a display device and a driving method, and the gate driving circuit comprises a plurality of cascaded shift registers which comprise a plurality of cascaded shift registers in even-numbered stages and a plurality of cascaded shift registers in odd-numbered stages; a signal input end of a first-stage shift register in the plurality of cascaded shift registers is configured to be coupled with an odd number frame trigger signal end, and a signal input end of a second-stage shift register in the plurality of cascaded shift registers is configured to be coupled with an even number frame trigger signal end; in every two adjacent shift registers in the odd-level shift registers, the signal input end of the next-level odd-level shift register is configured to be coupled with the cascade signal end of the previous-level odd-level shift register; in every two adjacent shift registers in the even-level shift registers, the signal input end of the next-level even-level shift register is configured to be coupled with the cascade signal end of the previous-level even-level shift register.
Description
Technical field [0001] The present invention relates to the field of display technology, and more particularly to a gate driving circuit, a display panel, a display device, and a driving method. Background technique [0002] With the rapid development of display technology, the display device has become more and more in terms of high integration and low cost. Among them, GOA (GATE DRIVER ON ARRAY, array substrate row driving) technology integrates TFT (Thin Film Transistor, thin film transistor) gate control circuit on the array substrate of the display device to form a scanning drive of the display device. The gate control circuit is typically constituted by a plurality of cascaded shift registers. [0003] Usually, in order to compatibility with low power and high performance, existing display devices are often compatible with high and low frequency drives, and achieve adjustments for display refresh rates 1 Hz to 120 Hz. Among them, at high refresh rate, the pixel charge is la...
