Implementations described herein generally relate to the use of display screens. More specifically, implementations generally relate to a large format transmissive and self-emissive display screen where the display screen includes multiple screens coupled together using transparent adhesive tape. Implementations described herein minimize internal reflections visible to screen viewers when an edge of the adhesive layer is scanned by a beam spot produced by a scanning beam in a scanning beam system having multiple screens held together by the adhesive layer to form a seamless viewing screen. In some implementations, the internal reflections are minimized by applying the adhesive layer between horizontal and vertical seams between each screen of the multiple screens wherein the adhesive layer has non-straight edges so as to minimize the total surface area of the edge of the adhesive layer that falls within the beam spot produced by the scanning beam.
