Abstract

A flat-panel display apparatus has a display unit with dual-axis adjustment capability. A cable supplying display signals and electrical power to the display unit passes through a vertically-oriented hinge shaft rotatably connecting the display unit to a stand unit, thus preventing an undesired twisting of the cable.

Claims

1. A flat-panel display apparatus, comprising:

a display unit displaying images according to a display signal and being supplied with electrical power;

a stand unit comprised of a body terminated at a first extremity by a bottom surface slidably engaging any underlying surface supporting said stand unit, said body supporting said display unit continuously positioned directly above said bottom surface while said display unit is oriented to extend beyond a second extremity of said body at selected angles within a range of angles of tilt relative to said bottom surface as said bottom surface moves in any direction across an underlying surface supporting said stand unit;

a hinge unit, rotatably connecting said display unit to said stand unit while allowing said display unit to rotate about a first shaft through said range of angles of-tilt, said hinge unit comprised of a hinge shaft radially spaced-apart from said first shaft and providing a hollow passage between said second extremity and said hinge unit;

a cable, supplying the display signal and electrical power to said display unit, passing through said hinge shaft while said hinge unit rotates about said hinge shaft relative to said body;

an interface circuit board located in said stand unit; and

a main circuit board located in said display unit;

said cable connecting said interface circuit board and said main circuit board.

2. The apparatus according to claim 1, wherein said cable connects with said main circuit board within said display unit.

3. A flat-panel display apparatus, comprising:

a display unit displaying images according to a display signal and being supplied with electrical power;

a stand unit supporting said display unit;

a hinge unit, rotatable connecting said display unit to said stand unit, comprised of a hinge shaft; and

a cable, supplying the display signal and electrical power to said display unit, passing through said hinge shaft;

wherein said hinge unit comprises;

a hinge body having a shaft insertion hole; and

a shaft received in said shaft insertion hole, said hinge body being rotatable about the shaft;

said shaft, conducting said cable therethrough, comprising a rib extending therefrom;

said shaft insertion hole having a shape complementary of said rib;

whereby association and disassociation of said shaft and said hinge body is accomplished only when said rib is aligned with said shaft insertion hole.

4. The hinge of claim 3, said hinge body further comprising a rotation guide, configured to be rotated within a rotary guide recess of said stand unit, extending therefrom.

5. The hinge of claim 3, said hinge body further comprising a projection, configured to restrict rotation of said hinge body between a first stop and a second stop, extending therefrom.

6. The hinge of claim 5, said first stop comprising an elastic projection extending from a rotary guide recess of a stand.

7. The hinge of claim 6, said elastic projection being biased relative to the rotary guide recess.

8. The hinge of claim 5, said second stop comprising a retainer extending from a rotary guide recess of a stand.

9. The hinge of claim 3, said shaft being generally vertical in orientation.

10. The hinge of claim 3, said hinge body further comprising a bracket, configured to be mounted on said display housing, rotatably mounted thereon.

11. The hinge of claim 10, said bracket being rotatable about a generally horizontal axis.

12. The hinge of claim 3, further comprising a cover mounted on said hinge body.
