The invention discloses a flip transparent reelable flexible film LED display screen and a production process thereof. The display screen comprises a transparent film, circuit layers, driving ICs, flip LED chips and a transparent adhesive; the display screen totally comprises multiple layers of structures, which are a first flexible film, a first circuit layer, a second flexible film, a second circuit layer, a third flexible film, a third circuit layer and the like sequentially from bottom to top; circuits and the high-temperature-resistant flexible films are superposed to present a multilayerFPC flexible circuit board; the LED chips are welded on the FPC flexible circuit board in a flip mode; and the driving ICs are arranged on the FPC flexible circuit board. The flip LED chips are directly welded on the FPC flexible circuit board, so that the costs of traditional lamp bead supports, gold wires, patches and the like are reduced; and connecting boards are provided with bonding pads, and through mutual connection of the bonding pads, a user can carry out free splicing according to actual requirements, so that the size of the LED flexible screen is determined.
