The present invention provides an analog memory cell circuit for the LTPS TFT-LCD. At least one, but preferably two springs in the form of two thin strips of metal attach to post at the side edge of the mirror and act as springs which provide a restoring force when the mirror is tilted between an OFF state which occurs when the mirror is flat relative to the substrate with no voltage applied, and in the ON state when the mirror is tilted when a voltage is applied. The torque transmitting devices may include clutches and at least one brake.
