Description

Curved support structure and curved display thereof

The present invention provides a support structure and related liquid crystal display, and more particularly to a curved support structure and a curved display thereof.

A conventional curved display uses a curved support and at least one curved frame to form a backplane structure to fix the display panel in a predetermined curved state. The size of the single-piece curved frame used in the backplane structure is equivalent to the size of the curved support. The single-piece curved frame is attached to the curved support by a fixing member, and the curved frame provides the main strength of the back-plate structure. Alternatively, the backsheet structure may use a plurality of small-sized curved frames that are smaller in size than the curved bracket. A plurality of small-sized curved frames are connected in a partially overlapping manner to be fixed to the curved bracket. Most of the traditional backplane structures provide the main structural strength from the curved frame, and the curved bracket provides an auxiliary local reinforcement strength. However, the conventional curved frame is formed by press forming, and the curved frames of different sizes are to be independently opened, which is relatively expensive to manufacture.

The present invention provides a curved support structure having low cost and high versatility and a curved display thereof to solve the above problems.

The patent application scope of the present invention discloses a curved support structure for use in a curved display. The curved support structure comprises a planar back plate, a curved bracket and a plurality of fixing members. The curved bracket has a fixed structural curvature in a long axis direction. The curved bracket includes an opposite one The plate and the lower plate are not equal in length or width. The fixing members are combined with the lower plate and the planar back plate. The planar backplane is structurally deformed by the limitation of the fixing members in combination with the curved bracket, such that the planar backing plate is attached to the curved bracket along the curvature of the structure.

The scope of the invention further discloses a curved display comprising a curved support structure, a plurality of optical films, a frame and a panel unit. The curved support structure comprises a planar back plate, a curved bracket and a plurality of fixing members. The curved bracket has a fixed structural curvature in a long axis direction. The curved bracket includes an upper plate and a lower plate, the upper plate and the lower plate being unequal in length or width. The fixing members are combined with the lower plate and the planar back plate. The planar backplane utilizes the limits of the fasteners to create structural deformation relative to the curved bracket such that the planar backplane is attached to the curved bracket along the curvature of the structure. The plurality of optical films are disposed on the upper plate of the curved bracket, and the frame is disposed on a side of the curved support structure. The panel unit is disposed on the frame and above the optical film.

The invention utilizes a fixing member to apply an external force on the planar back plate to cause structural deformation of the planar back plate to be attached to the curved bracket. The curved bracket is used to provide the main strength of the curved support structure and curved display. The curved bracket made by the bending process can be arbitrarily changed according to the length, the curvature and the radius, so that the mold can be shared with the plane bracket, and the production cost of the curved bracket can be effectively saved. Compared with the prior art, the present invention provides a solution for a curved support structure and a curved display thereof which are easy to manufacture, low in cost, and easy to assemble.
