Back LCD impact absorbing structure of electronic apparatus and electronic apparatus having the structure
View Patent ↗This invention provides an electronic apparatus having a back display portion and a back LCD impact absorbing structure capable of preventing a front LCD from being broken through a back LCD by a load applied from a rear cover. A rear cover has a back screen attaching portion to which a back screen is attached and a back LCD display window opened by being surrounded by the back screen attaching portion on the surface and a back dustproof cushion on the back of the cover. The longitudinal one side in four sides of a back LCD display window which forms a cutout portion is broadened like a half-moon shape and thereby, a direct influence on this portion of a back LCD due to an external force added to the rear cover is moderated.
1. An LCD dustproof structure of an electronic apparatus including a first case having a front LCD display window and a second case having a back LCD display window and on which a housing is formed in accordance with engagement with the first case, comprising:
an LCD unit which includes a front LCD set to the first case, a back LCD set to the second case, and printed wiring board having an electronic component and a wiring for LCD control and which is built in the housing; wherein
a back screen is attached to a planar portion of a surface of the second case which overlaps the back LCD, and a back dustproof cushion for dustproof between the back screen and the back LCD is attached to the periphery of the back LCD display window on the back, and
a cutout portion formed in the planar portion of the surface of the second case for moderating the direct influence of an external force applied to the second case on the back LCD, the cutout portion being formed as one side of the back LCD display window.
2. The LCD dustproof structure of an electronic apparatus according to claim 1 , wherein
the cutout portion is formed like a half-moon shape.
3. The LCD dustproof structure of an electronic apparatus according to claim 1 , wherein
the front LCD is set to a face opposite to the back LCD.
4. The LCD dustproof structure of an electronic apparatus according to claim 1 , wherein
the cutout portion is formed in a convex shape.
5. An electronic apparatus including a first case having a front LCD display window and a second case on which a housing is formed in accordance with engagement with the first case, comprising:
an LCD unit which includes a front LCD set to the first case, a back LCD set to the second case, and a printed wiring board having an LCD control electronic component and a wiring and which is built in the housing; wherein
a back screen is attached to a planar portion of a surface of the second case which overlaps the back LCD, and a back dustproof cushion for dustproof between the back screen and the back LCD is attached to the periphery of the back LCD display window on the back, and
a cutout portion formed in the planar portion of the surface of the second case for moderating the direct influence of an external force applied to the second case on the back LCD, the cutout portion being formed as one side of the back LCD display window.
6. The electronic apparatus according to claim 5 , wherein
the cutout portion is formed like a half-moon shape.
7. The electronic apparatus according to claim 5 , wherein
the front LCD is set to a face opposite to the back LCD.
8. The electronic apparatus according to claim 5 , wherein
the electronic apparatus is a cellular phone.
9. The electronic apparatus according to claim 8 , wherein
the cellular phone is foldaway.
