In the early Universe, dark energy may have a non-negligible contribution. If this dark energy corresponds to an early cosmological constant, it leads to a late-time huge dark energy density which is much larger than what is expected for the current expansion of the Universe. Using a conformal coupling of the quintessence to the dark matter, and based on the screening models, we propose a process to reduce the early dark energy to its ultimate value in the late time. Early and late-time dark energies can be unified in a single component, in this way.
