Abstract

A liquid crystal display including many speakers within a stand and having a display unit, a display angle of which can be adjusted by a cam in order that a user can conveniently see it. The stand supports the display unit through a support and has an inclined part between a front part and a rear part. In addition, a speaker for outputting a high-pitched sound is installed within the front part of the stand and speakers for outputting a middle-low pitched sound are installed within the both sides of the stand. The support is rotatably connected to the display unit and the stand by a driving of the cam and contacted with the cam provided to toe inclined part of the stand and the angle of the support is adjusted by a rotation of the cam and so an angle of the display unit is adjusted.

Claims

a support having first and second ends, the first end of said support rotatably connected to the rear part of said stand;

a display unit for displaying images, said display unit rotatably connected to the second end of said support for adjusting a display angle of the display unit; and

means located in said inclined section for adjusting a second display angle of the display unit.

2. The liquid crystal display of claim 1, said means further comprising:

a cam shaft;

a knob on one end of the cam shaft; and

a cam in the middle of said cam shaft for moving said support;

said means being rotatably installed in said inclination section.

3. The liquid crystal display of claim 2, further comprising:

said support having a concave surface in contact with said cam, for holding the support and the display unit.

4. The display of claim 2, further comprising:

said inclined section of the stand having a concavity;

said cam being oval in cross-section, the axis of said cam penetrated by a key hole, said cam rotatably installed in said concavity;

two shaft holes formed in the inclined section flanking the concavity, said shaft holes aligned with the axis of said cam;

said camshaft comprising;

a first camshaft, said first camshaft comprising;

a key section on the first camshaft; and

a hook along the axis of the first camshaft at the end of the key section; and

a knob on the first camshaft on the opposite end from the hook;

said first camshaft being installed through one shaft hole and the key section being inserted through the key hole of said cam; and

a second camshaft having a key hole and a hook hole formed in one end, said second camshaft being installed through the second shaft hole, said hook of said first camshaft being inserted into said hook hole and a portion of said key section being inserted into the key hole of the second camshaft.

5. The display of claim 2, further comprising:

said inclined section of the stand having a concavity;

said inclined section of the stand having two shaft holes, semicircular in cross-section, flanking the concavity;

a camshaft having a cam and two shaft portions flanking said cam;

said cam being oval in cross-section, said cam rotatably installed in said concavity and said; and

said shaft portions rotatably installed in said shaft holes; and

a cover, semicircular in cross-section, mounted to the inclined section and enclosing said shaft portions in said shaft holes.

6. The liquid crystal display of claim 1, further comprising:

said support being curved from said first to second ends, said curve being concave toward the front of the liquid crystal display.

7. The liquid crystal display of claim 1, further comprising:

said speaker inside the front part of the stand being for outputting high-pitched sound and said speakers in the sides of the stand being for outputting middle to low-pitched sound.

8. The liquid crystal display of claim 1, further comprising:

hinge protrusions on the on the upper and lower ends of the support;

said rear portion of the stand having holes for receiving the hinge protrusions on the lower end of the support; and

said display unit having holes for receiving the hinge protrusions on the upper end of the support.

9. A liquid crystal display, comprising:

a display unit displaying images in accordance with signals for displaying;

a stand supporting said display unit, being provided with a plurality of speakers in a front side as well as both sides, and including a curved front part, a rear part having a lower height than said front part and an inclined part between said front part and said rear part;

a support supporting said display unit to said stand, having one end portion rotatably connected to a rear side of said display unit and the other end portion rotatably connected to the rear part of said stand; and

a means located behind an upper portion of said support connected to the display unit in the inclined part of said stand for supporting said support and adjusting an angle of said display unit.

10. The display as claimed in claim 9, wherein said means is rotatably installed in the inclined part of said stand and includes a cam shaft having a knob in one side and a cam provided in a middle of said cam shaft to actuate said support.

11. The display as claimed in claim 10, wherein said support has a concave surface being contacted with said cam forming a part for indirectly adjusting an angle so as to be transmitted a weight of said display unit to the part for indirectly adjusting an angle.

12. The display as claimed in claim 10, wherein said cam, when rotated, is rotatably received in the concave provided in the inclined part of the stand and is stopped by being contacted with a bottom surface of said concave and said cam shaft is closely combined with a shaft hole formed in said stand.

13. The display as claimed in claim 9, wherein a speaker provided in the front part of said stand is for outputting a high-pitched sound while speakers provided in both parts of said stand are for outputting a middle-low pitched sound.

14. A liquid crystal display, comprising:

a display unit;

a stand for supporting the display unit, said stand having two side walls and a front part;

a support extending upwardly and slopingly from said stand to said display unit, one end thereof being pivotally connected to said stand and the other end being connected to said display unit;

means for adjusting a display angle of said display unit, said means being provided in said stand to contact and to support said support, said means including a cam shaft rotatably mounted on said stand, a knob formed on one end of said cam shaft, and a cam fixed to said cam shaft, said cam contacting a section of said support and rotating by said knob; and
