Specifically, the surface of the light-transmitting back plate 105 facing the flat panel display 101 is the back surface of the light-transmitting back plate 105, and the black material layer is located on the back surface of the light-transmitting back plate 105.
In this embodiment, a vacuum bonding technique is adopted to bond the light-transmitting back plate 105 and the curved screen 110, so as to form a curved screen structure. In other embodiments, a roller-type bonding technique may be used to bond the light-transmissive back surface to the curved screen.
Because the problem of wrinkles between the first bending part 102 and the second bending part 103 is avoided in this embodiment, adverse effects caused by the wrinkles on the attachment between the curved screen 110 and the light-transmitting back plate 105 are correspondingly avoided, so that the curved screen 110 and the light-transmitting back plate 105 have high attachment degree.
In the manufacturing method of the curved screen structure provided by the embodiment, the problem of wrinkles encountered when four sides are bent is solved by using a planar flexible screen cutting technology and a laminating technology, and the curved screen structure capable of realizing four-curved-surface display is obtained, and not only can the planar display be realized, but also the display can be realized on four side surfaces. In addition, the manufacturing method of the curved screen structure provided by the embodiment is simple and low in process cost.
It should be noted that, in other embodiments, when the number of the first bending regions is one, and the number of the second bending regions is one, the planar flexible screen correspondingly has a corner gap region, and accordingly, both adjacent two side edges of the planar display portion in the manufactured curved screen can realize curved display, and the problem of wrinkles is solved; when the number of the first bending areas is two and the number of the second bending areas is one, the planar flexible screen is correspondingly provided with two corner gap areas, correspondingly, the three adjacent side edges of the planar display part in the manufactured curved screen can realize curved surface display, and the problem of wrinkles is solved; when the number of the first bending areas is one and the number of the second bending areas is two, the planar flexible screen correspondingly has two corner gap areas, correspondingly, the three adjacent side edges of the planar display part in the manufactured curved screen can realize curved surface display, and the problem of folds is solved.
That is to say, the embodiment of the present invention can solve the problem of wrinkles encountered in curved surface display of adjacent sides of the flat display portion, so that the curved surface screen structure is no longer limited to curved surface display of opposite sides only of the flat display portion.
Correspondingly, the embodiment of the invention also provides a curved screen structure, and the curved screen structure can be manufactured by adopting the manufacturing method.
