Abstract
A back cover integrated with a light guide plate and a method of manufacturing the same, and a back light unit and a liquid crystal display device including the same are disclosed. The back cover integrated with a light guide plate comprises a reflective sheet attached onto a cover glass; a light guide plate attached onto the cover glass to cover the reflective sheet; and a light guide plate coupling member between the light guide plate and the cover glass.
Claims18
A back cover for a display device integrated with a light guide plate, comprising:
- a cover glass having a chamfer type corner portion;
- a reflective sheet attached onto the cover glass;
- the light guide plate attached onto the cover glass covering the reflective sheet;
- and
- a light guide plate coupling member between the light guide plate and the cover glass,
- wherein the light guide plate coupling member is arranged at an edge of the light guide plate.
A back cover for a display device integrated with a light guide plate, comprising:
- a cover glass having a rounded shape apex;
- a reflective sheet attached onto the cover glass;
- the light guide plate attached onto the cover glass covering the reflective sheet;
- and
- a light guide plate coupling member between the light guide plate and the cover glass,
- wherein the light guide plate coupling member is arranged at an edge of the light guide plate.
A liquid crystal display device comprising:
- a cover glass having a chamfer type corner portion;
- a reflective sheet attached onto the cover glass;
- a light guide plate attached onto the cover glass covering the reflective sheet;
- and
- a light guide plate coupling member between the light guide plate and the cover glass, wherein the light guide plate coupling member is arranged at an edge of the light guide plate;
- a liquid crystal panel on the light guide plate;
- a panel guide supporting the liquid crystal panel;
- a light source housing supporting the panel guide;
- and
- a light source module adjoining the light source housing, arranged to face the light incident surface.
A method of manufacturing a back cover integrated with a light guide plate, the method comprising:
- processing a corner of a cover glass to form a chamber type corner portion;
- strengthening the cover glass;
- printing a pattern on a surface where the cover glass is not exposed to the outside;
- bonding a reflective sheet to the cover glass;
- and
- bonding the light guide plate to the cover glass covering the reflective sheet.
