Abstract

A liquid crystal display TV includes a TV housing, and a reflective type liquid crystal display panel installed in the housing. A magnifying lens is disposed for magnifying an image on the display area and a support assembly is provided for supporting the magnifying lens to allow a space where the ambient light enters from above a display area of said liquid crystal display panel when the magnifying lens lens is in use. This arrangement allows full utilization of the ambient light for the optical performance of the liquid crystal display panel.

Claims

1. A liquid crystal display device comprising:

a housing;

a liquid crystal display panel mounted in said housing and producing a display image;

an optical lens magnifying said display image;

a support arm having said lens pivotially mounted on one end thereof and being pivitally mounted on said housing at the other end thereof, said support arm supporting said lens spaced apart from said display panel in a display mode and folding to place said lens in juxtaposition with said housing in a retracted mode.

2. The device of claim 1 wherein said lens is juxtaposed between said housing and said support arm when in the retracted mode to thereby protect said lens.

3. The device of claim 1 wherein said liquid crystl display panel is of the reflective type.

4. The device of claim 3 wherein said support arm has substantially the same width as said optical lens.

5. The device of claim 1 wherein said support arm is transparent.

6. The device of claim 5 wherein said support arm has substantially the same width as said optical lens.

7. The device of claim 1 wherein said support arm has an inner surface closest said display panel when in said display mode, said inner surface being reflective.

8. The device of claim 1 further comprising:

telescopic antenna means for receiving a television signal and controlling the angle of inclination of said housing with respect to a support surface,

said antenna being pivotally mounted to said housing and telescopically shortened to fold into juxtaposition with said housing when said device is in a retracted mode.

9. The device of claim 1 wherein said support arm has substantially the same width as said optical lens.

10. A liquid crystal display device comprising:

a housing;

a liquid crystal display panel mounted in said housing and producing a display image;

an optical lens magnifying said display image to produce an image directly viewable by the user;

means for supporting said optical lens at a distance from said display panel to enable magnification of said image, said support means retracting to move said lens into juxtaposition with said housing to facilitate compact storage of said device.
