  The $D_{s0}(2590)^{+}$ resonance observed by LHCb Collaboration is a strong
candidate of the $D_{s}(2^1S_0)$ 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
$D_{s0}(2590)^{+}$ resonance. The mass spectrum and strong decays of the
excited charmed-strange mesons are investigated within the modified relativized
quark model and $^3P_0$ model. The calculated mass and width of the
$D_{s0}(2590)^{+}$ are consistent with the experimental observations, which
indicate that it can be reasonably interpreted as the $D_{s}(2^{1}S_{0})$
state.
