  For a general maximally symmetric (spherically, plane or hyperbola symmetric)
holographic screen, we rewrite the equations of motion of general Lovelock
gravity into the form of some generalized first law of thermodynamics, under
certain ansatz. With this observation together with other two independent ways,
exactly the same temperature and entropy on the screen are obtained. So it is
argued that the thermodynamic interpretation of gravity is physically
meaningful not only on the horizon, but also on a general maximally symmetric
screen. Moreover, the formula of entropy is further checked in the (maximally
symmetric) general static case and dynamical case. The entropy formula also
holds for those cases. Finally, the method of conical singularity is used to
calculate the entropy on such screen, and the result again confirms the entropy
formula.
