Whereas the display screen of the curved surface display device is curved, pictures can be mapped into the user's brain intuitively at the same angle, thus transformation for pictures need not to be performed by the brain, reducing the pressure of the brain.

DETAILED DESCRIPTION OF THE INVENTION

In the following, technical solutions of the embodiments of the invention will be described clearly and completely with reference to the figures for the embodiments. Apparently, the embodiments described are just part of the possible embodiments of the invention, but not the entire embodiments. Based on current embodiments of the invention, other embodiments obtained by the skilled person in the art without inventive efforts belong to the claimed scope of the invention.

As shown inFIG. 1, a curved surface display device is provided by an embodiment of the invention. The curved surface display device may comprise a liquid crystal display module11and at least one adjustment frame12, each adjustment frame12may comprise a first portion121and a second portion122. Both of the first portion121and the second portion122may comprise a fixed end and a movable end. The fixed end121aof the first portion121and the fixed end122aof the second portion122may be respectively attached to the two edges of the liquid crystal display module11that are perpendicular to the horizontal direction in case of being viewed normally. An adjustment distance d may be present between the movable end121bof the first portion121and the movable122bof the second portion122. The adjustment frame12may also be provided with an adjustment screw123, which may connect the movable end121bof the first portion121and the movable end122bof the second portion122. The adjustment frame12can be used for changing the size of the adjustment distance d by regulating the adjustment screw123, thus varying the curvature of the liquid crystal display module11by changing the size of the adjustment distance d.

It is noted that, the two edges of the liquid crystal display module11hereinafter refer to the two edges of the liquid crystal display11that are perpendicular to the horizontal direction in case of being viewed normally.

The fixed ends121aand122aof the adjustment frame12can be attached to the two edges of the liquid crystal display module11respectively. When the adjustment screw123is adjusted to reduce the adjustment distance d, the force applied on the movable ends121band122bof the adjustment frame12will be transferred to the fixed ends121aand122aof the adjustment frame12, which in turn acts on the two edges of the liquid crystal display module11. Then the liquid crystal display module11may be bent due to the extrusion force from the two edges, thus the curvature of the liquid crystal display module11can be changed. The fixed ends121aand122aof the adjustment frame12can be attached to the two edges of the liquid crystal display module11in various ways, which is not limited by the embodiments of the invention, for example, the fixed ends121aand122aof the adjustment frame12can be embedded into the module backplane at the two edges of the liquid crystal display module11, or the fixed ends121aand122aof the adjustment frame12can be welded to the module backplane at the two edges of the liquid crystal display module11, alternatively, the fixed ends121aand122aof the adjustment frame12can also be fixed to the plastic frame of the liquid crystal display module11. However, since the plastic frame of the liquid crystal display module11is a plastic injection part, which is easy to be deformed when suffered great pressure. While the module backplane of the liquid crystal display module11may be a metal part with strong compression resistance capability, hence it is preferred that the adjustment frame12is attached to the module backplane.

The adjustment frame12may be made from high-strength metal parts, thus it is difficult to be deformed under stress. For example, materials such as high-strength aluminium alloy, high-strength alloy steel or metal plate can be used to form the adjustment frame, which is not limited by the embodiments of the invention.

The liquid crystal display module11may comprise a liquid crystal display screen and a backlight component. It is noted that, the fabrication and assembly of the liquid crystal display screen and the backlight component of the liquid crystal display module11in the embodiments of the invention can be performed in a flat state, the operation difficulty is decreased and the production process is simple and convenient, compared to the case of the prior art in which a curved backlight is needed to be fabricated and assembled.

In this way, compared with the prior art, for the curved surface display devices provided by the embodiments of the invention, by means of the adjustment screw, the size of the adjustment distance between the movable ends of the first portion and the second portion of the adjustment frame can be changed, so that the size of the distance between the two edges of the liquid crystal display module respectively attached to the fixed ends of the first portion and the second portion of the adjustment frame, thereby varying the curvature of the liquid crystal display module. Since the adjustment screw can be adjusted flexibly, the curvature of the liquid crystal display module can be adjusted flexibly. In the prior art, in the manufacture of a curved surface display device, all the components of the backlight are needed to be formed into curved shape, then the components with curved shape are assembled into a curved surface backlight. However, fabricating and assembling the curved surface backlight is difficult, technical cost of such process is very high, and the yield of which is relatively low, moreover, the plane display screen is easy to crumble when assembled onto the curved surface backlight, thus such assembling process faces great challenge. In contrast, the liquid crystal display modules of embodiments of the invention can be fabricated and assembled under a flat state, in the manufacture of the curved surfaced display device, it is needed simply to vary the curvature of the plane liquid crystal display by means of the adjustment frame and the adjustment screw, therefore, such process is easy to operate and may has a relatively higher yield, during which the display screen is not easy to crumble.

Further, as shown inFIG. 2, the liquid crystal display module11may comprise a module backplane111, the fixed end121aof the first portion121and the fixed122aof the second portion122may be respectively attached to the two edges of the module backplane111of the liquid crystal display module11that are perpendicular to the horizontal direction in case of being viewed normally.

The module backplane111may be used for supporting the backlight components and protecting the backlight components from being extruded. The module backplane111has relatively high strength, hence, it is not easy to be deformed even if under large extrusion force. Having attached the adjust frame12to the module backplane111, when the adjustment distance d is reduced by regulating the adjustment screw123, large extrusion force would be applied to the two edges of the liquid crystal display module11at the same time by the fixed end121aof the first portion121and the fixed end122aof the second portion122of the adjustment frame12, thus, under the influence of the extrusion force, the curvature of the liquid crystal display module11may be changed, i.e. the liquid crystal display module11can be bent.

In an embodiment, the adjustment frame12may be made from metal plate.

Since the metal plate has advantages of high strength, light weight and low cost, it can be employed to manufacture the adjustment frame12.

Further, at least one adjustment frame12can be axisymmetrically distributed, the symmetry axis may be the horizontal symmetry axis of the liquid crystal display module11in case of being viewed normally.

In practical application, the number of the adjustment frames12can be determined depending on the user's request or design requirement, which is not limited by embodiments of the invention. In an embodiment, the adjustment frames can be axisymmetrically distributed. For example, when only one adjustment frame12is arranged, the adjustment frame12may be arranged at the horizontal symmetry axis of the liquid crystal display module11in case of being viewed normally. When two adjustment frames12are arranged, the two adjustment frames may be symmetrically distributed about the horizontal symmetry axis of the liquid crystal display module11in case of being viewed normally. Similarly, a plurality of adjustment frames12can be symmetrically distributed, such arrangement may cause the two edges of the liquid crystal display module11to be under the same stress, therefore, the two edges of the liquid crystal display module11may have the same curve radian.

A curvature adjustment method for a curved surface display device is also provided by another embodiment of the invention. The method may comprise steps as follows:Step 1: regulating the adjustment screw123to reduce the adjustment distance d.Step 2: when the adjustment distance d is reduced, applying external force to the liquid crystal display module11such that the liquid crystal display module11approaches the adjustment frame12.

As shown inFIG. 1, in this case, the liquid crystal display module11is in a flat state, because the adjustment frame12does not apply force to the liquid crystal display module11. When regulating the adjustment screw123, i.e. further tightening the adjustment screw123, the adjustment distance d will be reduced. At the same time of tightening the adjustment screw123, external force in the Y direction can be applied to the liquid crystal display module11as shown inFIG. 3, then the liquid crystal display module11will be bent towards the direction to the adjustment frame12. The Y direction shown inFIG. 3may be the direction in which the liquid crystal display module11points to the adjustment frame12.

The curved surface display device provided by embodiments of the invention may comprise a liquid crystal display module, and may also comprise at least one adjustment frame. Each adjustment frame may comprise a first portion and a second portion, both of which may comprise a fixed end and a movable end. The fixed end of the first portion and the fixed end of the second portion may respectively be attached to the two edges of the liquid crystal display module that are perpendicular to the horizontal direction in case of being viewed normally. There may be an adjustment distance between the movable end of the first portion and the movable end of the second portion. The adjustment frame may also be provided with an adjustment screw, which may movably connect the movable end of the first portion and the movable end of the second portion. The adjustment frame may be 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. For the curved surface display devices provided by embodiments of the invention, the size of the adjustment distance between the movable ends of the first portion and the second portion of the adjustment frame may be changed by means of the adjustment screw, thus, the size of the distance between the two edges of the liquid crystal display module respectively attached to the fixed ends of the first portion and the second portion of the adjustment frame, thereby varying the curvature of the liquid crystal display module. Compared with the prior, the curvature of the liquid crystal display module can be adjusted flexibly, since the adjustment screw can be adjusted flexibly. In the prior art, in the manufacture of a curved surface display device, all the components of the backlight are needed to be formed into curved shape, then the components with curved shape are assembled into a curved surface backlight. However, fabricating and assembling the curved surface backlight is difficult, technical cost of such process is very high, and the yield of which is relatively low, moreover, the plane display screen is easy to crumble when assembled onto the curved surface backlight, thus such assembling process faces great challenge. In contrast, the liquid crystal display modules of embodiments of the invention can be fabricated and assembled in a flat state, the curved surfaced display device can be obtained just by adjusting the curvature of the plane liquid crystal display by means of the adjustment frame and the adjustment screw, therefore, such process is easy to operate and may has a relatively higher yield, during which the display screen is not easy to crumble.

In another embodiment of the invention, as shown inFIG. 4, a curved surface display device may comprise a liquid crystal display module41. The curved surface display device may also comprise at least one adjustment frame42. The body423of each adjustment frame42may comprise at least one via hole421. A module backplane411of the liquid crystal display module41comprises at least one screwed hole4111having female screw threads therein. Also the body423of the adjustment frame42may be provided with at least one adjustment screw422, which can connect the body423of the adjustment frame42with the module backplane411through the via hole421and the screwed hole4111. An adjustment distance dd may be present between the bottom of the body423of the adjustment frame42and module backplane411. The adjustment screw422is provided with male screw threads that matches the female screw threads inside the screwed hole4111. The adjustment frame42may be used to change the size of the distance dd by rotating the adjustment screw422, by which the curvature of the liquid crystal display module41can be varied.

The adjustment frame42may be provided with an adjustment screw422, the liquid crystal display module41may comprise a liquid crystal display screen and a backlight412as well as the module backplane411. The liquid crystal display screen, the backlight412and the module backplane411may be regarded as an integral part fixed together. As shown inFIG. 4, since the adjustment screw422in the adjustment frame42can be attached to the screwed hole4111of the module backplane411through the via hole421, when the adjustment screw422is rotated to reduce the distance dd, the module backplane411attached to the adjustment frame42will be bent towards the direction to the adjustment frame42, such that the liquid crystal display screen and the backlight412fixed to the module backplane411are also be bent towards the direction to the adjustment frame42, in this way, the curvature of the liquid crystal display module can be changed.

In practical application, a plurality of adjustment frames42can be arranged, each of which may comprise multiple via holes421. Specific number of the adjustment frame or via hole can be determined depending on actual situation, which is not limited by embodiments of the invention. Likewise, the module backplane411may have multiple screwed holes4111, the adjustment frame42may comprise a plurality of adjustment screws422, still, the specific number of the screwed holes or adjustment screws can be determined depending on actual situation, which is not limited by embodiments of the invention. The via hole421, the screwed hose4111and the adjustment screw422can be arranged as a complete set, for which the numbers and positions thereof can correspond to each other.

The adjustment frame42may be made from high-strength metal parts, thus it is difficult to be deformed even if under stress. For example, materials such as high-strength aluminum alloy, high-strength alloy steel or metal plate can be used to form the adjustment frame, which is not limited by the embodiments of the invention.

The liquid crystal display screen and the backlight components of the liquid crystal display module41provided by the embodiment of the invention can be fabricated and assembled in a flat state, compared to the prior art in which a curved surface backlight and a curved surface liquid crystal display screen are needed to be fabricated and assembled, such simple and convenient process is easy to operate and may has a relatively higher yield.

Thus, for the curved surface display device provided by the embodiment of the invention, by means of the adjustment screw, the size of the adjustment distance between the bottom of the body of the adjustment frame and the module backplane can be changed, so that the curvature of the liquid crystal display module can be varied. Compared with the prior art, the curvature of the liquid crystal display module can be adjusted flexibly, since the adjustment screw can be adjusted flexibly. In the prior art, in the manufacture of a curved surface display device, all the components of the backlight are needed to be formed into curved shape, then the components with curved shape are assembled into a curved surface backlight. However, fabricating and assembling the curved surface backlight is difficult, technical cost of such process is very high, and the yield of which is relatively low, moreover, the plane display screen is easy to crumble when assembled onto the curved surface backlight, thus such assembling process faces great challenge. In contrast, the liquid crystal display modules of embodiments of the invention can be fabricated and assembled under a flat state, the curved surfaced display device can be obtained just by adjusting the curvature of the plane liquid crystal display by means of the adjustment frame and the adjustment screw, therefore, such process is easy to operate and may has a relatively higher yield, during which the display screen is not easy to crumble.

Further, as shown inFIG. 4orFIG. 5, the two ends of the body423of the adjustment frame42may respectively cling to the two edges of the liquid crystal display module41that are perpendicular to the horizontal direction in case of being viewed normally.

It is noted that, the two edges of the liquid crystal display module41hereinafter refer to the two edges of the liquid crystal display41that are perpendicular to the horizontal direction in case of being viewed normally.

The “cling to” mentioned above means that the two ends of the body423of the adjustment frame42may be fixed to the two edges of the liquid crystal display module41, or the two ends of the body423of the adjustment frame42may abut against the two edges of the liquid crystal display module41, which is not limited by embodiments of the invention.

Due to the fact that the two ends of the body423of the adjustment frame42may respectively cling to the two edges of the liquid crystal display module41, the adjustment screw422can be fixed better between the adjustment frame42and the module backplane411. Also, when the adjustment screw422is adjusted, the two ends of the body423of the adjustment frame42may support the two edges of the liquid crystal display module41, such that the middle portion of the liquid crystal display module41may be bent towards the adjustment frame42, that is, the curvature of the liquid crystal display module41is varied.

In an embodiment, the adjustment frame42may be made from metal plate. Since the metal plate has advantages of high strength, light weight and low cost, it can be employed to manufacture the adjustment frame12.

Further, as shown inFIG. 4, the via holes421in each adjustment frame42can be distributed symmetrically about the center of adjustment frame.

The number of the via holes421in the adjustment frame42can be determined depending on user's request or design requirement, which is not limited by embodiments of the invention. The distribution of the via holes421in the adjustment frame42can be symmetrical about the center, for example, in case that only one via hole421is arranged, the via hole421may be arranged in the middle of the adjustment frame42; in case that tow via holes421are arranged, the two via holes421can be distributed symmetrically about the center line of the adjustment frame42as a symmetry axis. Similarly, multiple via holes421can be arranged symmetrically, such arrangement may cause the two edges of the liquid crystal display module41to be under the same stress, therefore, the two edges of the liquid crystal display module41may have the same curve radian.

In another embodiment, at least one adjustment frame42may be distributed axisymmetrically, the symmetry axis may be the horizontal symmetry axis of the liquid crystal display module in case of being viewed normally.

In practical application, the number of the adjustment frames42can be determined depending on specific request, which is not limited by embodiments of the invention. The distribution of the adjustment frames42can be axisymmetrical. For example, when only one adjustment frame42is arranged, the adjustment frame42may be arranged at the symmetry axis of the liquid crystal display module41in case of being viewed normally. When two adjustment frames42are arranged, distribution of the two adjustment frames may be symmetrical about the horizontal symmetry axis of the liquid crystal display module41in case of being viewed normally. Similarly, a plurality of adjustment frames42can be symmetrically distributed, such arrangement may cause the two edges of the liquid crystal display module41to be under the same stress, therefore, the two edges of the liquid crystal display module41may have the same curve radian.

The curved surface display device provided by the embodiment of the invention may comprise a liquid crystal display module, and also may comprise at least one adjustment frame, each adjustment frame may comprise at least one via hole. The module backplane of the liquid crystal display module may comprise at least one screwed hole having female screw threads therein. The adjustment frame may also comprise at least one adjustment screw, which can connect the body of the adjustment frame with the module backplane through the via hole and the screwed hole. There may be an adjustment distance between the bottom of the body of the adjustment frame and the module backplane. The adjustment screw is provided with male screw threads that match the female screw threads inside the screwed hole. The adjustment frame may be used to change the size of the adjustment distance by rotating the adjustment screw, by which the curvature of the liquid crystal display module can be varied. For the curved surface display device provided by the embodiment of the invention, the size of the adjustment distance between the bottom of the body of the adjustment frame and the module backplane can be changed by means of the adjustment screw, so that the curvature of the liquid crystal display module can be varied. Compared with the prior art, the curvature of the liquid crystal display module can be adjusted flexibly, since the adjustment screw can be adjusted flexibly. Moreover, in the prior art, in the manufacture of the curved surface display device, all the components of the backlight are needed to be formed into curved shape, then the components with curved shape are assembled into a curved surface backlight. However, fabricating and assembling the curved surface backlight is difficult, technical cost of such process is very high, and the yield is relatively low, moreover, the plane display screen is easy to crumble when assembled onto the curved surface backlight, thus such assembling process faces great challenge. In contrast, the liquid crystal display modules of embodiments of the invention can be fabricated and assembled under a flat state, a curved surfaced display device can be obtained just by adjusting the curvature of the plane liquid crystal display module by means of the adjustment frame and the adjustment screw, therefore, such process is easy to operate and may has a relatively higher yield, during which the display screen is not easy to crumble.
