The Ds0(2590)+ resonance observed by LHCb Collaboration is a strong candidate of the Ds(21S0) state according to its spin parity and strong decay mode. However, the measured mass seems relatively lower than the previous theoretical predictions, which interests the coupled channel interpretations in the literature. In this work, we adopt an alternate approach, taking into account the screening effects in the potential model, to describe the Ds0(2590)+ resonance. The mass spectrum and strong decays of the excited charmed-strange mesons are investigated within the modified relativized quark model and 3P0 model. The calculated mass and width of the Ds0(2590)+ are consistent with the experimental observations, which indicate that it can be reasonably interpreted as the Ds(21S0) state.
