Abstract
Abstract An impact-resistant display apparatus is constituted by a display panel, a drive circuit for driving the display panel, a face plate disposed in front of the display panel, and a support member for supporting the display panel and the drive circuit. The display apparatus further includes a first elastic member between a rear side of the display panel and the support member, and a second elastic member between a front side of the display panel and the face plate. The first and second elastic members may preferably respectively define and almost closed space together with adjacent associate members so as to provide an air damper-effect.

Claims Analysis
Total Claims: 14
Claim 1
Independent Claim
131 words
A display apparatus, comprising: a display panel, a housing member disposed behind and with a spacing from the display panel, and a face plate having a transparent region disposed in front of the display panel; said display apparatus further including: a first elastic member disposed at a position surrounding a display region of the display panel between the display panel and the housing member so as to define a first almost closed space by the first elastic member, the display panel and the housing member, and a second elastic member disposed at a position surrounding a display area of the display panel between the display panel and the face plate so as to define a second almost closed space by the second elastic member, the display panel and the face plate.
Claim 2
Dependent Claim
131 words
A display apparatus, comprising: a display panel, a housing member disposed behind and with a spacing from the display panel, and a face plate having a transparent region disposed in front of the display panel; said display apparatus further including: a first elastic member disposed at a position surrounding a display region of the display panel between the display panel and the housing member so as to define a first almost closed space by the first elastic member, the display panel and the housing member, and a second elastic member disposed at a position surrounding a display area of the display panel between the display panel and the face plate so as to define a second almost closed space by the second elastic member, the display panel and the face plate.
Claim 3
Dependent Claim
22 words
A display apparatus according to claim 1, further comprising a drive circuit including a flexible film circuit connected to the display panel.
Claim 4
Dependent Claim
48 words
A display apparatus according to claim 1, further comprising a drive circuit including a rigid circuit board and a flexible film circuit carrying a drive IC chip thereon, said rigid circuit board being connected to the flexible film circuit which in turn is connected to the display panel.
Claim 5
Dependent Claim
47 words
A display apparatus according to claim 1, wherein said first elastic member has a sectional shape having a thickness in a direction perpendicular to the display panel and a width in a direction parallel to the display panel so that the width is smaller than the thickness.
Claim 6
Dependent Claim
21 words
A display apparatus according to claim 1, wherein the face plate has a transparent portion comprising a chemically reinforced glass sheet.
Claim 7
Dependent Claim
33 words
A display apparatus according to claim 1, wherein said face plate comprises a transparent substrate and a pair of optical films subjected to a non-glare treatment applied onto both surfaces of the substrate.
Claim 8
Dependent Claim
20 words
A display apparatus according to claim 1, wherein said housing member comprises a backlight device for illuminating the display panel.
Claim 9
Dependent Claim
28 words
A display apparatus according to claim 1, wherein said second elastic member has a hardness which is smaller than or equal to that of the first elastic member.
Claim 10
Dependent Claim
22 words
A display apparatus according to claim 1, wherein said second elastic member is compressed in a direction perpendicular to the display panel.
Claim 11
Dependent Claim
38 words
A display apparatus according to claim 1, further including a circuit board for driving the display panel disposed on the panel-fixing member, and a regulating member for regulating a movement in a direction perpendicular to the panel-fixing member.
Claim 12
Dependent Claim
26 words
A display apparatus according to claim 1, wherein said display panel comprises a liquid crystal panel containing a smectic liquid crystal as an optical modulation material.
Claim 13
Dependent Claim
119 words
A display apparatus according to claim 1, wherein there is defined an inner unit which includes the face plate as a first member and a second member as a portion of said housing member disposed with a prescribed spacing from the first member, the display panel disposed between the first and second members, the second elastic member disposed between the first member and the display panel, and the first elastic member disposed between the second member and the display panel, so as to define the first almost closed space by the display panel, the second member and the first elastic member, and the second almost closed space by the display panel, the first member and the second elastic member.
Claim 14
Dependent Claim
21 words
