Protective window and display device including the same
View Patent ↗In one aspect, a protective window comprising a first transparent member comprising a polymer; and a protective layer on a first surface of the first transparent member and comprising silsequioxane is provided.
1. A protective window comprising:
a first transparent member comprising a polymer;
a protective layer which is formed directly on a first surface of the first transparent member and comprises silsequioxane; and
a second transparent member comprising a plurality of layers formed directly on a second surface of the first transparent member, wherein the second transparent member contains at least one of polycarbonate (PC), PMMA, and PET, and a lowest layer of the second transparent member is a PC layer;
wherein the protective layer has a thickness of 100 to 150 μm,
wherein a thickness of the protective layer is greater than a thickness of the first transparent member, and
wherein a thickness of the second transparent member is greater than the thickness of the protective layer.
2. The protective window of claim 1 , wherein the polymer is polymethylmethacrylate (PMMA) or polyethylene terephthalate (PET).
3. The protective window of claim 1 , wherein the polymer is PET, the second transparent member contains PMMA, the first transparent member has a thickness of approximately 50 μm, and the second transparent member has a thickness of approximately 0.5 mm or more.
4. The protective window of claim 1 , wherein the polymer is PMMA, the second transparent member contains PMMA, the first transparent member has a thickness of approximately 50 μm, and the second transparent member has a thickness of approximately 0.8 mm or more.
5. The protective window of claim 1 , further comprising an adhesive member under the second transparent member.
6. The protective window of claim 1 , wherein the first surface of the first transparent member comprises a first region and a second region, wherein the protective layer is disposed on the first region.
7. The protective window of claim 6 , further comprising a third transparent member which is disposed on the second region and contains a polymer, wherein the protective layer has the same thickness as the third transparent member.
8. The protective window of claim 6 , wherein the first transparent member comprises a protruding portion on the second region, wherein a height of the protruding portion on the first surface of the first transparent member is equal to the thickness of the protective layer.
9. A protective window comprising:
a first transparent member comprising a polymer, and comprising a plurality of layers;
a protective layer which is formed directly on a first surface of the first transparent member and comprises silsequioxane; and
a rear layer which is formed directly on a second surface of the first transparent member and contains silsequioxane;
wherein the protective layer has a thickness of 100 to 150 μm,
wherein a layer of the first transparent member which contacts the rear layer is a PC layer,
wherein a thickness of the protective layer is greater than a thickness of the first transparent member, and
wherein a thickness of the rear layer is greater than the thickness of the protective layer.
10. The protective window of claim 9 , wherein the rear layer has a thickness of approximately 100 to 150 μm.
11. The protective window of claim 9 , wherein the polymer is PMMA or PET.
12. The protective window of claim 9 , further comprising an adhesive member under the rear layer.
13. A display device comprising:
a display unit; and
a protective window which is disposed over the display unit,
wherein the protective window comprises:
a first transparent member which contains a polymer;
a protective layer which is formed directly on a first surface of the first transparent member and contains silsequioxane; and
a second transparent member comprising a plurality of layers, and is formed directly on a second surface of the first transparent member, wherein the second transparent member comprises at least one of polycarbonate (PC), PMMA, and PET, and a lowest layer of the second transparent member is a PC layer;
wherein the protective layer has a thickness of 100 to 150 μm,
wherein a thickness of the protective layer is greater than a thickness of the first transparent member, and
wherein a thickness of the second transparent member is greater than the thickness of the protective layer.
14. The display device of claim 13 , wherein a surface of the display unit which faces the protective window comprises a first display unit region and a second display unit region, wherein the protective layer is disposed above the first display unit region.
15. The display device of claim 14 , wherein the protective window comprises a third transparent member comprising a polymer, situated above the second display unit region, and is disposed on the first surface of the first transparent member.
16. The display device of claim 15 , wherein the first display unit region is a display region, and the second display unit region is a non-display region.
17. The display device of claim 13 , wherein the polymer is PMMA or PET.
18. The display device of claim 13 , wherein the protective window comprises a rear layer which is formed on the second surface of the first transparent member and comprising silsequioxane.
