Flat panel display apparatus
View Patent ↗A flat panel display apparatus including a display unit, a cover covering the display unit, and a film disposed on the cover. The film has one or more protrusions, each having a reflective first surface and a transparent second surface. The first surface can include a coating. The second surface transmits light from the display unit, at a first angle, and the second surface reflects external light at a second angle.
1. A flat panel display apparatus comprising:
a display unit;
a cover to cover the display unit; and
a film disposed on the cover, having protrusions that extend away from the cover,
wherein each of the protrusions has a first surface having a first reflectivity, and a second surface that intersects the first surface and has a second reflectivity that is different from the first reflectivity.
2. The flat panel display apparatus of claim 1 , wherein the first surfaces are coated with coatings.
3. The flat panel display apparatus of claim 1 , wherein:
the first surfaces of the film are coated with first coatings;
the second surfaces are coated with second coatings; and
the thickness of the first coatings is different from the thickness of the second coatings.
4. The flat panel display apparatus of claim 1 , wherein:
the first surfaces are disposed at a first angle, with respect to the cover; and
the second surfaces are disposed at a second angle, with respect to the cover, which is different than the first angle.
5. The flat panel display apparatus of claim 1 , wherein:
the second surfaces are disposed at the same angle, with respect to the cover;
the first reflectivity is greater than the second reflectivity; and
at least two of the first surfaces are disposed at different angles, with respect to the cover.
6. The flat panel display apparatus of claim 1 , wherein the protrusions are parallel lengthwise and have polygonal cross-sections.
7. The flat panel display apparatus of claim 6 , wherein the protrusions have triangular cross-sections.
8. The flat panel display apparatus of claim 1 , wherein the cover and the film are integrally formed as a single body.
9. The flat panel display apparatus of claim 1 , wherein second surfaces have a higher surface roughness than the first surfaces.
