A method improves the respondability of moveable structures in a display medium, such as a gyricon display. The inventive method includes heating the display and exercising the rotatable structures within the display by an application of an electrical field. Applying heat to the display enlarges the cavity surrounding each particle due to thermal expansion of the cavity and the bead rotation cycling jostles the particles loose. The inventive method enables a larger percentage of the particles to rotate to a greater degree thereby improving resolution of an image. Alternatively, heating and exercising can be accomplished by application of ultrasonics. In addition, degassing the fluid contained in the display enhances switching with heat and improves the rotatability of the structures.
