Abstract

The present invention provides a curved liquid crystal display device, which includes a backlight module ( 1 ), a mold frame ( 3 ) mounted on the backlight module ( 1 ), a liquid crystal panel ( 5 ) arranged on the mold frame ( 3 ), and a bezel ( 7 ) that retains the liquid crystal panel ( 5 ) on the mold frame ( 3 ). The backlight module ( 1 ) includes a curved backplane ( 11 ) and optical components ( 13 ) arranged in the curved backplane ( 11 ). The curved backplane ( 11 ) includes a bottom board ( 111 ) and a bracing ( 9 ) mounted to the bottom board ( 111 ). The bracing ( 9 ) includes a base ( 91 ), a pair of guide rails ( 93 ) mounted to the base ( 91 ), a screw ( 95 ) rotatably mounted to the base ( 91 ), and a pair of slide blocks ( 97 ) that are in engagement with the screw ( 95 ) and slidable along the guide rails ( 93 ). The bottom board ( 111 ) includes a pair of protrusions ( 113 ) formed a surface thereof that is in contact engagement with the slide blocks ( 97 ) to correspond to the slide blocks ( 97 ). The pair of slide blocks ( 97 ) are arranged to respectively press against the pair of protrusions ( 113 ) so as to cause deformation of the bottom board ( 111 ) to form the curved backplane ( 11 ).

First claim

What is claimed is:

1. A curved liquid crystal display device, comprising a backlight module, a mold frame mounted on the backlight module, a liquid crystal panel arranged on the mold frame, and a bezel that retains the liquid crystal panel on the mold frame, the backlight module comprising a curved backplane and optical components arranged in the curved backplane, the curved backplane comprising a bottom board and a bracing mounted to the bottom board, the bracing comprising a base, a pair of guide rails mounted to the base, a screw rotatably mounted to the base, and a pair of slide blocks that are in engagement with the screw and slidable along the guide rails, the bottom board comprising a pair of protrusions formed a surface thereof that is in contact engagement with the slide blocks to correspond to the slide blocks, the pair of slide blocks being arranged to respectively press against the pair of protrusions so as to cause deformation of the bottom board to form the curved backplane.

2. The curved liquid crystal display device as claimed in claim 1 , wherein the curved backplane is made of a material having an excellent property of elasticity.

3. The curved liquid crystal display device as claimed in claim 2 , wherein the curved backplane is made of spring steel or plastics.

4. The curved liquid crystal display device as claimed in claim 1 , wherein the guide rails are made of a material of high stiffness and having strength greater than strength of the curved backplane.

5. The curved liquid crystal display device as claimed in claim 1 , wherein the bracing comprises a pair of mounting pieces arranged at a middle portion, the pair of mounting piece being fixedly mounted to the bottom board.

6. The curved liquid crystal display device as claimed in claim 5 , wherein the mounting pieces each comprise a mounting section and a connection section connected to the mounting section, the mounting section being planar and fixedly attached by a bolt to a central portion of the bottom board, the connection section being fixedly connected to the base or the guide rails.

7. The curved liquid crystal display device as claimed in claim 5 , wherein the pair of slide blocks is respectively set at opposite sides of the mounting pieces, the pair of slide blocks being arranged in opposite directions.

8. The curved liquid crystal display device as claimed in claim 7 , wherein the pair of slide blocks is arranged to be symmetric with respect to the mounting pieces, each of the slide blocks comprising a guide face that gradually presses against the corresponding protrusion of the bottom board.

9. The curved liquid crystal display device as claimed in claim 8 , wherein the pair of slide blocks gradually and respectively presses against the pair of protrusions from inner sides of the protrusions, the guide faces being curved surfaces or slope surfaces that are arranged to face the protrusions.

10. The curved liquid crystal display device as claimed in claim 1 , wherein each of the guide rails has a cross section that is in the form of an inverted L-shape and comprises a planar guide section, the guide sections of the pair of guide rails opposing each other, the slide blocks comprising a pair of slide channels formed therein to be respectively in sliding engagement with the guide sections of the guide rails, each of the slide blocks comprising a threaded hole formed therein to mate the screw, whereby rotation of the screw causes the pair of slide blocks to slide in opposite directions.

11. A curved liquid crystal display device, comprising a backlight module, a mold frame mounted on the backlight module, a liquid crystal panel arranged on the mold frame, and a bezel that retains the liquid crystal panel on the mold frame, the backlight module comprising a curved backplane and optical components arranged in the curved backplane, the curved backplane comprising a bottom board and a bracing mounted to the bottom board, the bracing comprising a base, a pair of guide rails mounted to the base, a screw rotatably mounted to the base, and a pair of slide blocks that are in engagement with the screw and slidable along the guide rails, the bottom board comprising a pair of protrusions formed a surface thereof that is in contact engagement with the slide blocks to correspond to the slide blocks, the pair of slide blocks being arranged to respectively press against the pair of protrusions so as to cause deformation of the bottom board to form the curved backplane;
wherein the curved backplane is made of spring steel or plastics;
wherein the guide rails are made of a material of high stiffness and having strength greater than strength of the curved backplane;
wherein the bracing comprises a pair of mounting pieces arranged at a middle portion, the pair of mounting piece being fixedly mounted to the bottom board;
wherein the mounting pieces each comprise a mounting section and a connection section connected to the mounting section, the mounting section being planar and fixedly attached by a bolt to a central portion of the bottom board, the connection section being fixedly connected to the base or the guide rails;
wherein the pair of slide blocks is respectively set at opposite sides of the mounting pieces, the pair of slide blocks being arranged in opposite directions;
wherein the pair of slide blocks is arranged to be symmetric with respect to the mounting pieces, each of the slide blocks comprising a guide face that gradually presses against the corresponding protrusion of the bottom board;
wherein the pair of slide blocks gradually and respectively presses against the pair of protrusions from inner sides of the protrusions, the guide faces being curved surfaces or slope surfaces that are arranged to face the protrusions; and
wherein each of the guide rails has a cross section that is in the form of an inverted L-shape and comprises a planar guide section, the guide sections of the pair of guide rails opposing each other, the slide blocks comprising a pair of slide channels formed therein to be respectively in sliding engagement with the guide sections of the guide rails, each of the slide blocks comprising a threaded hole formed therein to mate the screw, whereby rotation of the screw causes the pair of slide blocks to slide in opposite directions.
