Embodiment Construction
[0028] As stated in the background, there are technical problems in the prior art. The inventor found that the reason for this problem is that the 3D bonding process is carried out by laminating upwards with a soft substance (silica gel) in a vacuum environment, and the bonding process is designed by means of computer-aided design (CAE). However, due to the selection of design parameters, fluctuations in silica gel material, inconsistent product characteristics of the screen body, and inconsistent characteristics of the bonding materials (polarizers, optical glue), there are deviations between CAE and reality. CAE fits perfectly, and the four corners of reality will appear. Different degrees of bubbles, pitting, etc., but due to the curvature of the 3D bonded cover (CG) and the inability of the vacuum chamber to connect to the pressure test instrument, there is no effective means to perfectly test the pressure generated after the entire bond, and the bond The inspection of the...

The embodiment of the invention provides a pressure detection system, which solves the technical problem that the lamination effect cannot be determined and a laminating process cannot be improved in a targeted manner due to the fact that a pressure change cannot be detected in a curved surface laminating technology in the prior art. According to the pressure detection system provided by the embodiment of the invention, image data of different to-be-detected parts are obtained by adopting multiple groups of images; the image data of different parts of different to-be-detected articles are subjected to 3D synthesis and converted into two-dimensional images; and then the two-dimensional images are subjected to feature extraction to obtain pressure profiles of whole articles of the to-be-detected articles, thereby clearly detecting the pressure profiles of various parts of the to-be-detected articles. When pressure changes before and after a cover plate is laminated with a flexible display screen in the curved surface laminating process need to be detected, pressure change distribution in the curved surface laminating process can be known just through separately detecting and comparing pressure distribution before and after lamination, thereby improving the laminating process in a targeted manner.
Description
technical field [0001] The invention relates to the field of display technology, in particular to a pressure detection system, a pressure detection method and a pressure change detection method. Background technique [0002] Flexible display panel technology is now the mainstream display panel technology. The flexible display panel on the market is mainly used in terminals with curved edges, but it is necessary to bond the flexible display panel The method used for lamination is mainly 3D curved surface lamination technology. However, since the pressure change cannot be detected during the lamination process, there are problems that the lamination effect is uncertain and the lamination process cannot be improved in a targeted manner. Contents of the invention [0003] In view of this, the embodiment of the present invention provides a pressure detection system, which solves the technical problems in the prior art that the pressure change cannot be detected in the curved su...
