The invention relates to a filter screen. In order to solve the technical problems in the dynamic filter screen in the prior art, the invention provides a dynamic multilayer composite endless filter screen which comprises a surface screen, a bottom screen and at least one fine filter screen positioned between the surface screen and the bottom screen. The dynamic multilayer composite endless filter screen is characterized in that the surface screen, bottom screen and fine filter screen are square-hole endless screens and are respectively woven from a resin material; the hole sizes of the surface screen and bottom screen are respectively greater than the hole size of the fine filter screen; and the surface screen, bottom screen and fine filter screen are compounded into an integral body under the action of the same expansion force. The filter screen can obviously enhance the water passing efficiency, and has longer service life.
