Abstract
Official abstract text for this publication.
An apparatus includes a substrate; a display panel on the substrate; and a protective film protecting one of the substrate and the display panel, wherein the protective film includes a first protective film and a second protective film, wherein the first protective film is disposed closer to the display panel than the second protective film, and wherein the first protective film includes a polymerizable compound having an adhesive strength that changes with energy irradiated onto the polymerizable compound.
First claim
Opening claim text (preview).
What is claimed is: 1 . A protective film for protecting a display panel, comprising: a first protective film; and a second protective film, wherein the first protective film includes a polymerizable compound having an adhesive strength that changes with energy irradiated onto the polymerizable compound. 2 . The protective film of claim 1 , wherein the first protective film is configured to have an adhesive strength of 3.0 gf/inch to 12.5 gf/inch after the energy is irradiated thereto. 3 . The protective film of claim 1 , wherein the polymerizable compound includes a multi-functional monomer. 4 . The protective film of claim 1 , wherein the adhesive strength of the first protective film changes with ultraviolet light applied thereto. 5 . The protective film of claim 1 , wherein the first protective film is closer to the display panel than the second protective film. 6 . The protective film of claim 1 , wherein the display panel is one of a liquid crystal panel, an organic light emitting display panel, a touch panel, a touch panel on a liquid crystal panel, and a touch panel on an organic light emitting display panel. 7 . The protective film of claim 1 , wherein a functional layer is attached on the display panel after removing the protective film. 8 . The protective film of claim 7 , wherein the functional layer comprises at least one among a backplate, a polarizer, a cover window, and a touch panel. 9 . The protective film of claim 8 , wherein at least one among the substrate, the backplate, the polarizer, the cover window, and the touch panel is flexible. 10 . A display apparatus, comprising: a substrate; a display panel on the substrate; and a protective film protecting one of the substrate and the display panel, wherein the protective film comprises a first protective film and a second protective film, wherein the first protective film is disposed closer to the display panel than the second protective film, and wherein the first protective film includes a polymerizable compound having an adhesive strength that changes with energy irradiated onto the polymerizable compound. 11 . The display apparatus of claim 10 , wherein the adhesive strength of the first protective film changes with ultraviolet light applied thereto. 12 . The display apparatus of claim 10 , wherein the polymerizable compound includes a multi-functional monomer. 13 . The display apparatus of claim 10 , wherein the protective film is configured to have an adhesive strength of 3.0 gf/inch to 12.5 gf/inch after the energy is irradiated thereto. 14 . The display apparatus of claim 10 , wherein a functional layer is attached on the substrate or the display panel after removing the protective film. 15 . The display apparatus of claim 14 , wherein the functional layer comprises at least one among a backplate, a polarizer, a cover window, and a touch panel. 16 . The display apparatus of claim 15 , wherein at least one among the substrate, the backplate, the polarizer, the cover window, and the touch panel is flexible. 17 . The display apparatus of claim 10 , wherein the display panel is one of a liquid crystal panel, an organic light emitting display panel, a touch panel, a touch panel on a liquid crystal panel, and a touch panel on an organic light emitting display panel.
