By taking the particle-triaxial-rotor model with variable moment of inertia, we systematically investigate the energy spectra, deformations, and single-particle configurations of the nuclei {sup 183,185,187}Tl. The calculated energy spectra agree quite well with experimental data. The obtained results indicate that the rotation-aligned bands observed in {sup 183,185,187}Tl originate from one of the [530](1/2){sup -},[532](3/2){sup -},[660](1/2){sup +} proton configurations coupled to a prolate deformed core. Furthermore, the negative parity bands built upon the (9/2){sup -} isomeric states in {sup 183,185,187}Tl are formed by a proton with the [505](9/2){sup -} configuration coupled to a core with triaxial oblate deformation, and the positive parity band on the (13/2){sup +} isomeric state in {sup 187}Tl is generated by a proton with configuration [606](13/2){sup +} coupled to a triaxial oblate core.
