Specifically, the back plate 1 may be curved along a direction convex to the display surface of the back plate 1, or may be bent along a direction convex to the backlight surface of the back plate 1, and the curvature of the back plate 1 is determined according to a front convex radius of the display surface of the display module required by the user, which is not limited in the embodiment of the present application. The backlight surface and the light receiving surface of the back plate 1 are two opposite surfaces of the back plate 1, and the light receiving surface of the back plate 1 is the surface of the back plate 1 facing the user. The curvature is a numerical value of a degree of curvature of the curve at a certain point, and the larger the curvature is, the larger the degree of curvature of the curve is, and the curvature of the backplate 1 is a numerical value of a degree of curvature of the backplate 1 in a predetermined direction.

specifically, the bending driving assembly 2 includes a first rotating plate 201, a second rotating plate 202, and an elastic balance member 203. The first rotating plate 201 and the second rotating plate 202 are both elongated plates, and the lengths of the first rotating plate 201 and the second rotating plate 202 are equal to ensure that the force components of the elastic balance pieces 203 applied to the first rotating plate 201 and the second rotating plate 202 are equal. In addition, the first rotating plate 201 and the second rotating plate 202 are both frame-shaped plate structures, specifically, the first rotating plate 201 and the second rotating plate 202 may be rectangular frame-shaped structures, and further, a cavity may be formed in the first rotating plate 201 and the second rotating plate 202, and the cavity may reduce the weight of the whole bending driving assembly 2, and may reserve sufficient installation space for other fixing members. Next, the elastic balance member 203 is a member having an elastic force and capable of restoring its own amount of deformation. When the external force is applied, the elastic balance member 203 can be deformed in the direction opposite to the applied force, and when the external force is removed, the elastic balance member can be restored to its original shape.

Specifically, as shown in fig. 6 and 7, the elastic balance member 203 may include a first connecting member, a second connecting member, and an elastic member 2031; a first mounting cavity is formed at one end of the first connecting piece, a second mounting cavity is formed at one end of the second connecting piece, the first mounting cavity and the second mounting cavity are oppositely arranged, the other end of the first connecting piece is hinged with the first end of the first rotating plate 201, and the other end of the second connecting piece is hinged with the first end of the second rotating plate 202; both ends of the elastic member 2031 are respectively embedded in the first and second mounting cavities.

When the installation, can inlay the one end of elastic component 2031 in the first installation cavity that first connecting piece formed, inlay the other end of elastic component 2031 in the second installation cavity that the second connecting piece formed, and then make first connecting piece, second connecting piece and elastic component 2031 can form a whole, and can provide installation space for first rotating plate 201 through first connecting piece, provide installation space for second rotating plate 202 through the second connecting piece, make things convenient for first rotating plate 201, second rotating plate 202 and elastic balance member 203 to be connected more.

It should be noted that both ends of the elastic balance member 203 are respectively hinged to the first end of the first rotating plate 201 and the first end of the second rotating plate 202, so as to equally distribute the applied force to the first end of the first rotating plate 201 and the first end of the second rotating plate 202 through the elastic balance member 203. In this way, since the second ends of the first rotating plate 201 and the second rotating plate 202 are movably connected to the back plate 1, the middle portion of the first rotating plate 201 has a first fulcrum, and the middle portion of the second rotating plate 202 has a second fulcrum, the first rotating plate 201 and the second balance plate form a structure similar to a "balance beam", when the first end of the first rotating plate 201 and the first end of the second rotating plate 202 are acted by a force in a first direction, the first rotating plate 201 can rotate around the first fulcrum, and the second rotating plate 202 can rotate around the second fulcrum, so that the second end of the first rotating plate 201 and the second end of the second rotating plate 202 can be acted by a force in a second direction, wherein the first direction and the second direction are opposite.

In addition, both ends of the elastic balance member 203 may be hinged to the first end of the first rotating plate 201 and the first end of the second rotating plate 202 by a hinge member such as a pin or a rotating shaft, respectively.

In addition, in the case where the back plate 1 is bent in a predetermined direction, the elastic balance pieces 203 are deformed in the predetermined direction, and then the first rotating plate 201 is driven to rotate around the first fulcrum, the second rotating plate 202 is driven to rotate around the second fulcrum, until the curvature of a first arc line formed by connecting lines between the fixed point of the first rotating plate 201 and the back plate 1, the fixed point of the second rotating plate 202 and the back plate 1, the hinged point of the first rotating plate 201 and the elastic balancing piece 203, and the hinged point of the second rotating plate and the elastic balancing piece 203 is consistent with the curvature of the bent back plate 1, the bending driving component 2 is arranged close to the back plate 1, i.e., the bending driving assembly 2 can provide a supporting force to the back plate 1, so that the back plate 1 is always maintained at a fixed curvature, in this case, the bending driving assembly 2 may be locked by the locking assembly 3 such that the backboard 1 is always supported by the bending driving assembly 2. It should be noted that the locking assembly 3 may include a locking screw, a clamping member, or the like, which can keep the first rotating plate 201, the second rotating plate 202, and the elastic balance member 203 relatively stationary, which is not limited in this embodiment of the application.

It should be further noted that the preset direction may be a direction along the light receiving surface of the back plate 1 as shown in fig. 2, or a direction along the backlight surface of the back plate 1 as shown in fig. 3, and the specific direction and the bending degree are determined according to the bending curvature requirement of the display module and the packaging and transportation requirement, which is not limited in the embodiment of the present application.

Specifically, in a possible implementation manner, as shown in fig. 2, in a case where the backplate 1 is bent in a direction protruding toward the light receiving surface of the backplate 1, the elastic balance member 203 receives a force shown as F in fig. 2, so that the elastic balance member 203 is deformed in a direction protruding toward the light receiving surface of the backplate 1, the elastic balance member 203 generates an elastic force after being deformed, and further drives the first end of the first rotating plate 201 and the first end of the second rotating plate 202 to move in a direction close to the backplate 1, under the action of the first fulcrum and the second fulcrum, the second end of the first rotating plate 201 and the second end of the second rotating plate 202 move in a direction away from the backplate 1, so that an included angle is formed between the first rotating plate 201 and the elastic balance member 203, so that an included angle is formed between the second rotating plate 202 and the elastic balance member 203, under the action of the elastic balance member 203, so that the moments received by the first rotating plate 201 and the second rotating plate 202 are equal, and the curvature of a first arc line formed by connecting lines between the fixing points of the first rotating plate 201 and the back plate 1, the fixing points of the second rotating plate 202 and the back plate 1, the hinge point of the first rotating plate 201 and the elastic balance piece 203 and the hinge point of the second rotating plate and the elastic balance piece 203 is always consistent with the curvature of the bent back plate 1, so that the back plate 1 is always supported by the bending driving assembly.

In another possible implementation manner, as shown in fig. 3, in the case that the backboard 1 is bent in the direction convex to the backlight surface of the backboard 1, the elastic balance member 203 is subjected to a force shown as N in fig. 2, so that the elastic balance member 203 is deformed in the direction convex to the backlight surface of the backboard 1, the elastic balance member 203 is deformed to generate an elastic force, and further the first end of the first rotating plate 201 and the first end of the second rotating plate 202 are driven to move in the direction away from the backboard 1, under the action of the first fulcrum and the second fulcrum, the second end of the first rotating plate 201 and the second end of the second rotating plate 202 are driven to move in the direction close to the backboard 1, so that an included angle is formed between the first rotating plate 201 and the elastic balance member 203, so that an included angle is formed between the second rotating plate 202 and the elastic balance member 203, under the action of the elastic balance member 203, the moments received by the first rotating plate 201 and the second rotating plate 202 are equal, and the curvature of a first arc line formed by connecting lines between the fixing points of the first rotating plate 201 and the back plate 1, the fixing points of the second rotating plate 202 and the back plate 1, the hinge point of the first rotating plate 201 and the elastic balance piece 203 and the hinge point of the second rotating plate 202 and the elastic balance piece 203 is always consistent with the curvature of the back plate 1, so that the back plate 1 is always supported by the bending driving assembly.

After the curvature of the backboard 1 reaches the preset value, the bending driving assembly 2 is locked through the locking assembly 3, and then the curvature of the bending of the display module is kept at a fixed value. Afterwards, when needs adjustment display module curved camber such as packing or transport, if the curved camber of display module when making is great, is unfavorable for packing and transport, then can fall locking Assembly 3 through dismantling for backplate 1 reaches and predetermines behind the camber, again through locking Assembly 3 locking crooked drive assembly 2, and then makes display module's curved camber can carry out nimble adjustment according to the demand of reality.
