Abstract: The present disclosure provides a backlight module assembly, structural adjustment method thereof and display device. The backlight module assembly includes a plastic frame, a film and an adjustment sheet. The plastic frame is presented in a box shape with an opening on the top, and has side walls and a bottom wall, and a space enclosed by the side walls and the bottom wall being a mounting groove. The film is arranged on the bottom wall and received within the mounting groove. The adjustment sheet is arranged on an inner side of the side wall of the mounting groove.

Abstract: The present disclosure provides an LED light strip and a backlight module having the same. The LED light strip includes a circuit board; the circuit board has a board body and a support structure disposed on a surface of the board body; a plurality of LED light emitting elements are disposed on the support structure, the plurality of the LED light emitting elements are arranged in a plurality of rows and face to a first direction parallel to the board body; the arrangement direction of each row of the LED light emitting elements is a second direction that is parallel to the board body and perpendicular to the first direction; and the orthographic projections of the LED light emitting elements on a plane that is parallel to the second direction and perpendicular to the first direction are staggered from each other.
