The present disclosure provides a data driver circuit, a liquid crystal display device, and a driving method. The pawl and the spring, which do not require any fixed attachment to any other component of the device, are held in place and pivotable within a plate. Embodiments of the invention relating to the production of a cooling effect and the generation of electrical power, change the thermodynamic state of the system by extracting energy from a pressurized fluid. The final layer of the tape length is circumferentially wound around the penultimate tape layer so that the trailing end of the tape overlays the tab between the first and second ends of the tab.
