Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of display screens, and particularly relates to an adjustable calibration curved surface display screen. BACKGROUND

[0002] In the prior art, most conventional curved screens adopt fixed curvature, and the curvature adjustment function of the curved display screen is missing, so that dynamic adjustment is difficult to achieve, the display effect is affected, and different scene requirements cannot be flexibly adapted. Moreover, the support structure of the curved display screen has significant defects. The traditional design adopts a rigid frame, which cannot adapt to the bending requirements of the flexible curved screen. Some display screens adopt multiple fixed support plates. Since the flexible curved screen needs to be adapted to bending, a large bending gap needs to be reserved between the plates, which will cause the following problems: first, the support surface is discontinuous, stress concentration is easy to occur at the bending part, and long-term use may cause screen deformation or damage; second, the plates are fixedly connected and cannot move adaptively along the bending direction, which is easy to cause the display surface to be locally prominent, uneven or the display screen to be prominent and the curve to be not smooth at the splicing part of the two display screens, affecting the visual experience. Therefore, an adjustable calibration curved surface display screen is needed to solve the above problems. SUMMARY

[0003] Therefore, an adjustable calibration curved surface display screen with adjustable curvature, which can adaptively bend and provide a continuous support surface, is provided.

[0008] Further, the curved surface support module further comprises a fixing member comprising a left end fixing member, a right end fixing member and a middle fixing member. The curved surface support module is fixedly connected with the left and right box frames and the middle box frame through the left end fixing member, the right end fixing member and the middle fixing member respectively.

[0013] Further, a plurality of positioning grooves are equidistantly arranged along a bending direction of the curved rack, an arc-shaped bending direction of the arc-shaped limiting hole is consistent with the bending direction of the curved rack, and the limiting pin and the arc-shaped limiting hole are matched to limit a moving range of the transmission gear, thereby avoiding disengagement of the transmission gear and the curved rack.

[0014] Further, the rotation adjusting assembly further comprises a locking gear, a locking bracket, a rotating disc and a locking button, the locking button being connected with the rotating disc, the locking bracket being connected with the first mounting frame, the locking gear being coaxially fixed with the transmission gear and located between the transmission gear and the driving member, the locking bracket being provided with an insertion hole, a glass bead limiting groove, a limiting tooth member and a torsion spring connected with the limiting tooth member, the locking button being internally provided with an elastic glass bead, the rotating disc being provided with a pushing block penetrating into the locking bracket from the insertion hole, when the locking button is pressed, the rotating disc is rotated, the elastic glass bead is clamped into the glass bead limiting groove, the pushing block is synchronously pressed against the limiting tooth member, the limiting tooth member is clamped with the locking gear, the locking gear is locked, and the transmission gear is locked.

[0016] Compared with the prior art, the display screen has at least the following beneficial effects:

[0017] First, the curvature is adjustable. By rotating the driving member to drive the transmission gear to engage with the curved rack, the left and right frames can be rotated relative to the middle frame, the display screen is bent, and the curvature can be dynamically adjusted in real time to be an inner arc, an outer arc, an S-shaped spline curve and the like. The elastic positioning member is engaged with the positioning groove, so that the curvature adjustment is stable and can be repeatedly adjusted.

[0018] Second, the plurality of supporting members are self-adaptively moved in the waist-shaped hole of the spring steel sheet through the connecting column, so as to form a continuous supporting surface which can be self-adaptively curved, thereby solving the stress concentration problem of the traditional flat plate support at the curved part and the problem of local protrusion and unevenness of the display screen.
