Abstract

The embodiment of the invention relates to the field of display technology, and provides a curved surface display device whose curvature can be adjusted flexibly after assembly. The curved surface display device may comprise a liquid crystal display module, and may also comprise at least one adjustment frame, each adjustment frame comprises a first portion and a second portion, both of the first portion and the second portion comprise a fixed end and a movable end, the fixed end of the first portion and the fixed end of the second portion are respectively attached to the two edges of the liquid crystal display module that are perpendicular to the horizontal direction in case of being viewed normally; an adjustment distance is present between the movable end of the first portion and the movable end of the second portion, the adjustment frame is provided with an adjustment screw which movably connects the movable end of the first portion and the movable end of the second portion; the adjustment frame is used for changing the size of the adjustment distance by regulating the adjustment screw, so as to vary the curvature of the liquid crystal display module. Embodiments of the invention may be used for manufacturing the curved surface display device.

First claim

The invention claimed is:

1. A curved surface display device comprising:
a liquid crystal display module having a first vertical edge and a second vertical edge;
at least one adjustment frame comprising:
a first portion having a fixed end and a moveable end;
a second portion having a fixed end and a moveable end;
wherein the fixed end of the first portion is attached to the first vertical edge of the liquid crystal display module and the fixed end of the second portion is attached to the second vertical edge of the liquid crystal display module;
an adjustment distance between the movable end of the first portion and the movable end of the second portion; and
an adjustment screw which movably connects the movable end of the first portion and the movable end of the second portion;

wherein adjusting the adjustment screw changes the adjustment distance, causing the adjustment frame to alter a curvature of the liquid crystal display module; and
wherein the curvature of the liquid crystal display module increases with a decrease of the adjustment distance.

2. The curved surface display device of claim 1 , wherein:
the liquid crystal display module comprises a module backplane having a first vertical edge and a second vertical edge; and
the fixed end of the first portion is attached to the first vertical edge and the fixed end of the second portion is attached to the second vertical edge.

3. The curved surface display device of claim 1 , wherein the adjustment frame is made from metal plate.

4. The curved surface display device of claim 2 , wherein the adjustment frame is made from metal plate.

5. The curved surface display device of claim 1 , wherein the at least one adjustment frame are axisymmetrically distributed relative to a horizontal symmetry axis of the liquid crystal display module.

6. The curved surface display device of claim 2 , wherein the at least one adjustment frame are axisymmetrically distributed relative to a horizontal symmetry axis of the liquid crystal display module.

7. A curvature adjustment method for a curved surface display device comprising:
providing a curved surface display device comprising:
a liquid crystal display module having a first vertical edge and a second vertical edge;
at least one adjustment frame comprising:
a first portion having a fixed end and a moveable end;
a second portion having a fixed end and a moveable end;
wherein the fixed end of the first portion is attached to the first vertical edge of the liquid crystal display module and the fixed end of the second portion is attached to the second vertical edge of the liquid crystal display module;

an adjustment distance between the movable end of the first portion and the movable end of the second portion; and
an adjustment screw which movably connects the movable end of the first portion and the movable end of the second portion;
wherein adjusting the adjustment screw changes the adjustment distance, causing the adjustment frame to alter a curvature of the liquid crystal display module; and
wherein the curvature of the liquid crystal display module increases with a decrease of the adjustment distance;

adjusting the adjustment screw to reduce the adjustment distance; and
applying a force to the liquid crystal display module when the adjustment distance is reduced such that the liquid crystal display module approaches the adjustment frame.
