Embodiment

[0052] as follows figure 1 The curvature detection of the curved backplane shown is taken as an example, and the curvature measurement device of the present application is further described in detail. The two opposite mounting bases 1 are both stepped, and the two first support surfaces 11 have mounting holes, which are fixed to the positioning beam 2 by bolts. The two second support surfaces 12 are provided with pads, and the pads are provided with upward columnar protrusions for inserting into the positioning holes of the test piece 3, and the pads are fixed on the second support surface 12 by hexagonal M6*10 screws. Above, the two pads need to be kept level.

Abstract

The invention provides a curvature detection device, which comprises a positioning beam, a length measuring rod and a mounting base, and is characterized in that the positioning beam is provided witha through hole, and the length measuring rod can be arranged in the through hole in a penetrating manner and can move in the through hole along a first direction; the first end of the length measuringrod is used for contacting with the concave surface of a to-be-measured piece; the mounting base is used for fixing the positioning beam and the to-be-tested piece, so that the positioning beam and the to-be-tested piece are oppositely arranged in the first direction. The length measuring rod which can be arranged on the positioning beam is contacted with the surface of the curved surface to-be-measured piece, and the reading on the length measuring rod is read to obtain the chord height, so that the curvature is calculated.

Description

technical field [0001] The present application relates to the field of display technology, and in particular, to a curvature detection device. Background technique [0002] With the development of display technology and people's pursuit of innovative display effects, it is necessary to consider a variety of module display forms. Curved display is more in line with ergonomics and can present a display effect with a more realistic viewing angle, which has become a growing object. [0003] For surface display, the size of the curvature and the tolerance fluctuation have a crucial impact on the final effect of the display. Therefore, it is very important to accurately measure the curvature of the surface display structure to improve the display effect. However, there is currently no curvature detection device designed for curved surface display. [0004] It should be noted that the information disclosed in the above background technology section is only used to enhance the un...
