Abstract: The present application provides a gate driving circuit and a display panel. The gate driving circuit includes a plurality of cascaded gate driving units, where each of the plurality of cascaded gate driving units includes a pull-up control module, an inversion module and a feedback module. The potential of the pull-up node is stepwise increased by the pull-up control module, so that the feedback module can be controlled to be turned off by the inversion module when the potential of the pull-up node is lower, thereby improving a phenomenon of leakage of the pull-up node through the feedback module.

Abstract: Embodiments of the present application disclose an encapsulation material, a display panel, and an encapsulation method. By mass percentage, the encapsulation material includes a main resin, 20%-50%; a dilute monomer, 20%-50%; a stabilizer, 0.01%-2%; a microgel, 1%-10%; a chain transfer agent, 0.01%-5%; and an initiator in a remaining percentage balance. The encapsulation material can be cured under action of UV light to form an encapsulation layer, anti-aging performance of the encapsulation layer can be improved, and toughness can be enhanced to reduce warpage. The microgel structure can enhance the toughness of the encapsulation layer and make it have excellent corrosion resistance. Ester activated vinyl sulfonate is used as the chain transfer agent to make an average chain length in a polymer network shorter, reduce a risk of shrinkage cracks appearing during curing, and enhance the toughness of the encapsulation layer after the curing.
