Possible Lorentz invariance violation (LIV) has been investigated for a long time based on observations of GRBs. These arguments relied on the assumption that photons with different energy are emitted at the same place and time. In this work, we try to take account of the intrinsic time delay Δtint between emissions of low and high energy photons by using the magnetic jet model. The possible LIV effects are discussed in a unified scenario both for long and short Fermi-detected GRBs. This leads to a unique quantum gravity energy scale M1c2 ∼ 1.0 × 1020 GeV respecting the linear dispersion relation.
► For the first time, GRB models are used to consider possible LIV effects in GRBs.
► Both intrinsic time lags and possible LIV induced time lags are considered.
► The constraints of LIV effects can be unified for both long and short bursts.
