JUNYOUNG LEE; JUNWOO YOU; SUNG-WOON IM - Web page: https://patentgrep.com/patent/US20250098508A1 ## CPC - H10K 59/88: Dummy elements, i.e. elements having non-functional features - H10K: ORGANIC ELECTRIC SOLID-STATE DEVICES ## Abstract A display panel transfer method includes providing a coating layer onto a rear surface of a display panel and providing an impact preventing layer onto a rear surface of the coating layer, wherein an area of the display panel is smaller than an area of the impact preventing layer and is larger than an area of the coating layer when viewed on a plane. ## Claims ### Claim 1 A display panel transfer method, the method comprising: providing a coating layer onto a rear surface of a display panel; and providing an impact preventing layer onto a rear surface of the coating layer, wherein an area of the display panel is smaller than an area of the impact preventing layer, and wherein the area of the display panel is larger than an area of the coating layer when viewed on a plane. ### Claim 2 (depends on 1) The display panel transfer method of claim 1, wherein the impact preventing layer is defined by a cured protective resin and wherein the providing an impact preventing layer includes: preparing a mold; providing a protective resin into the mold; providing the display panel and the coating layer onto the protective resin; curing the protective resin to create the cured protective resin; and removing the mold from the impact preventing layer. ### Claim 3 (depends on 2) The display panel transfer method of claim 2, wherein the mold is optically transparent. ### Claim 4 (depends on 2) The display panel transfer method of claim 2, wherein the protective resin includes an ultraviolet ray curing material. ### Claim 5 (depends on 4) The display panel transfer method of claim 4, wherein the protective resin includes an acryl-based or urethane-based material. ### Claim 6 (depends on 2) The display panel transfer method of claim 2, wherein the curing of the protective resin includes: a primary curing operation of curing the protective resin by irradiating the protective resin with a first ultraviolet ray; turning the mold and the protective resin over; and curing the protective resin by irradiating a rear surface of the mold with a second ultraviolet ray, wherein an intensity of the second ultraviolet ray is higher than an intensity of the first ultraviolet ray. ### Claim 7 (depends on 1) The display panel transfer method of claim 1, wherein the providing the display panel and the coating layer includes: disposing a metal frame defining an opening, on the rear surface of the display panel; and providing a resin onto the rear surface of the display panel through the opening, wherein the opening and the display panel overlap each other, and wherein an area of the opening is smaller than the area of the display panel when viewed on a plane. ### Claim 8 (depends on 1) The display panel transfer method of claim 1, wherein peripheries of the impact preventing layer are disposed on an outer side of peripheries of the display panel when viewed on a plane. ### Claim 9 (depends on 8) The display panel transfer method of claim 8, further comprising: providing the display panel, the coating layer, and the impact preventing layer into an accommodation groove defined in a tray or a jig. ### Claim 10 (depends on 9) The display panel transfer method of claim 9, wherein the peripheries of the impact preventing layer contact the tray or the jig, and the peripheries of the display panel are spaced apart from an inside of the tray or the jig. ### Claim 11 (depends on 9) The display panel transfer method of claim 9, further comprising: removing the impact preventing layer from the coating layer. ### Claim 12 (depends on 1) The display panel transfer method of claim 1, wherein the coating layer includes: a first base layer; and a plurality of first fillers dispersed within the first base layer. ### Claim 13 A display panel transfer method comprising: preparing a display panel; and providing a coating layer onto a rear surface of the display panel, wherein the providing a coating layer includes: providing a flat part, wherein the flat part extends along a first direction and a second direction crossing the first direction; and providing a plurality of protrusions disposed adjacent to peripheries of the flat part, wherein an area of the flat part is smaller than an area of the display panel when viewed on a plane. ### Claim 14 (depends on 13) The display panel transfer method of claim 13, wherein the flat part and the protrusions are formed at the same time. ### Claim 15 (depends on 14) The display panel transfer method of claim 14, wherein the protrusions are disposed on opposite sides of the flat part to be opposed to each other in the first direction and opposite sides of the flat part to be opposed to each other in the second direction. ### Claim 16 (depends on 13) The display panel transfer method of claim 13, wherein a plurality of removal grooves are defined between the flat part and the protrusions. ### Claim 17 (depends on 16) The display panel transfer method of claim 16, further comprising: separating the flat part and the protrusions along the removal grooves. ### Claim 18 (depends on 15) The display panel transfer method of claim 15, further comprising: separating the flat part and the protrusions by irradiating borders of the flat part and the protrusions with a laser beam. ### Claim 19 (depends on 13) The display panel transfer method of claim 13, wherein portions of the protrusions are disposed on an outer side of peripheries of the display panel when viewed on a plane. ### Claim 20 (depends on 19) The display panel transfer method of claim 19, wherein peripheries of the flat part are disposed on an inner side of the peripheries of the display panel when viewed on a plane.
