Abstract

A composition for packaging an electronic device comprises a matrix and an adsorption material having a water vapor adsorption capability, and the adsorption material includes attapulgite and/or zeolite. By adding attapulgite and/or zeolite which have an adsorption effect to modify the formulation of the frit, the compositions for packaging an electronic device can effectively reduce the influence of water vapor on the electronic device, thereby effectively extending the lifetime of the packaged electronic device.
