View Patent ↗An information processing apparatus including a display portion; a backlight unit configured to irradiate light from a rear face side of the display portion; a rear frame having height equivalent to at least a thickness of the backlight unit, and configured to protect the backlight unit; and an outer circumference casing attached to the rear frame, or formed integrally with the rear frame, and provided along an outer circumference of the display portion.
1. An information processing apparatus comprising:
a display portion including an edge portion having two intersecting surfaces;
a backlight unit configured to irradiate light from a rear face side of the display portion;
a rear frame having height equivalent to at least a thickness of the backlight unit, and configured to protect the backlight unit; and
an outer circumference casing attached to the rear frame, or formed integrally with the rear frame, and provided along an outer circumference of the display portion, the outer circumference casing defining a thickness dimension, a transverse dimension, and a longitudinal dimension and being longer in the longitudinal dimension than in the thickness dimension and longer in the longitudinal dimension than in the transverse dimension,
wherein the outer circumference casing is formed of a rigid member and includes an intersection of two surfaces forming an edge parallel to the longitudinal dimension, one of the two surfaces of the outer circumference casing has at least one groove portion formed therein, and the edge portion of the display portion is adhered to the outer circumference casing by an adhesive agent which is formed on both of the two surfaces of the outer circumference casing to contact both of the two surfaces of the edge portion of the display portion,
wherein the at least one groove portion has a first end portion, a center portion, and a second end portion that are separated in a direction parallel to the edge and to the longitudinal dimension, the at least one groove portion having a depth that gradually increases from the first end portion to the center portion and gradually decreases from the center portion to the second end portion, and wherein the at least one groove portion is an adhesive agent holding unit for fixing the adhesive agent between the outer circumference casing and the display portion.
2. The information processing apparatus of claim 1 , wherein the outer circumference casing is attached to the rear frame with an additional adhesive.
3. The information processing apparatus of claim 1 , wherein
the outer circumference casing is formed integrally with the rear frame by outsert molding or casting.
4. The information processing apparatus of claim 1 , wherein
the backlight unit includes a light emitting unit configured to emit light, and a light guide configured to guide light emitted from the light emitting unit into a predetermined portion.
5. The information processing apparatus of claim 4 , wherein
the rear frame includes an opening into which a portion of the light guide is inserted.
6. The information processing apparatus of claim 5 , wherein
the rear frame includes a notch portion in which a light emitting element of the backlight unit is disposed, and
a flexible substrate of the backlight unit is disposed above the notch portion of the rear frame and in contact with the light emitting element.
7. The information processing apparatus of claim 6 , wherein
the backlight unit includes the light emitting element, a light guide, an optical plate and the flexible substrate, and
a reflector and the light guide are disposed in the opening of the rear frame.
8. The information processing apparatus of claim 7 , wherein
the light guide and light emitting element are disposed so as to be in contact with the flexible substrate.
9. The information processing apparatus of claim 1 , wherein
the rear frame includes a groove portion configured to fix the adhesive agent.
10. The information processing apparatus of claim 1 , wherein
the outer circumference casing includes an adhesive agent holding portion configured to hold the adhesive agent in a predetermined location.
11. The information processing apparatus of claim 1 , wherein
the outer circumference casing has a substantially rectangular shape surrounding the outer circumference of the display portion, and a cross section of each side portion of the outer circumference casing is substantially L-shaped.
12. The information processing apparatus of claim 1 , wherein
the rear frame includes a notch portion on at least one transverse side on which a flexible substrate of the backlight unit is disposed.
13. The information processing apparatus of claim 12 , wherein
the backlight unit includes a light emitting element, a light guide, an optical plate and the flexible substrate, and
a cushion sheet, a reflector, the light guide, the light emitting element and the optical plate are sequentially disposed on a surface of the rear frame.
14. The information processing apparatus of claim 13 , wherein
the light guide and light emitting element are disposed so as to be in contact with the flexible substrate.
