Abstract
Official abstract text for this publication.
A display apparatus includes light-emitting elements configured to emit light in a screen, a louver fixed on the screen with a fastener, and a member disposed on a surface of the louver around the fastener and configured to reflect, in multiple directions, external light incident to a portion around the fastener or absorb the external light.
First claim
Opening claim text (preview).
What is claimed is: 1 . A display apparatus comprising: light-emitting elements configured to emit light in a screen; a louver fixed on the screen with a fastener; and a member disposed on a surface of the louver around the fastener and configured to reflect external light in multiple directions or absorb the external light, the external light being incident to a portion around the fastener. 2 . The display apparatus according to claim 1 , wherein the member is an annular protrusion surrounding the fastener. 3 . The display apparatus according to claim 1 , wherein the member is a plurality of the protrusions surrounding the fastener. 4 . The display apparatus according to claim 3 , wherein the protrusions include at least one of a linear protrusion, an arc-shaped protrusion, or a pyramid-shaped protrusion. 5 . The display apparatus according to claim 1 , wherein the member is an uneven area disposed on the surface of the louver around the fastener. 6 . The display apparatus according to claim 1 , wherein the member is an anti-reflection member disposed on the surface of the louver around the fastener.
