By reading the detailed description of the preferred embodiments below, various other advantages and benefits will become apparent to those of ordinary skill in the art. The drawings are only used for the purpose of illustrating the preferred embodiments, and are not considered as a limitation to the present disclosure. Moreover, throughout the drawings, the same reference numerals are used to denote the same components. In the drawings:
The technical solutions in the embodiments of the present disclosure will be described clearly and thoroughly with reference to the accompanying drawings in the embodiments of the present disclosure. Obviously, the described embodiments are part of the embodiments of the present disclosure, not all of the embodiments. Based on the embodiments in the present disclosure, all other embodiments obtained by those of ordinary skill in the art without creative work shall fall within the protective scope of the present disclosure.
As shown in
The disadvantage of the above solution is that: the two rigid support plates 22 form an isolated body, respectively, and are not connected with each other, thus, in an Electro-Static Discharge (ESD) environment, static electricity may accumulate on one of the rigid support plates 22 and cannot be discharged, which may inevitably damage the foldable display screen, resulting in a defective foldable display screen, such as poor lines or abnormal display, etc.
The embodiments of the present invention provide a support structure and a manufacturing method thereof, and a foldable display screen, which are used to solve the problem of a defective foldable display screen caused by the inability of the existing support structure to discharge static electricity.
Referring to
In the embodiment of the present disclosure, the support structure 200 may be bonded and covered onto the flexible display panel by adhesive such as optically clear adhesive (OCA) and the like.
Referring to
a first support plate 201, which is made of flexible conductive material; that is, the first support plate 201 is bendable.
two second support plates 202 provided on the first support plate 201; the second support plates 202 are made of rigid conductive material, that is, the second support plates 202 are not bendable. The two second support plates 202 are spaced apart. A region where the two second support plates 202 are located forms a rigid body region of the foldable display screen, and a region between the two second support plates 202 forms a foldable region of the foldable display screen. According to the embodiment of the present disclosure, at least a part of a surface of each second support plate is in contact with the first support plate, so that these second support plates 202 can be electrically connected with each other through the first support plate 201 and static electricity can be discharged, and thus the foldable display screen is protected from being damaged by ESD.
Optionally, a side surface of the second support plate 202 facing the first support plate 201 has a recess region and a contact region, the recess region is provided with a recess, and the contact region is in contact with the first support plate 201;
the recess region is filled with adhesive 203 for bonding the first support plate 201 and the second support plate 202, and a surface of the adhesive 203 in contact with the second support plate 202 is flush with a surface of the contact region, so that the contact region of the second support plate 202 can contact the first support plate 201, and the first support plate 201 and the second support plate 202 can be bonded fully.
Referring to
In the embodiment of the present disclosure, since the contact regions of the second support plates of the support structure are in direct contact with the first support plate, at least two second support plates can be connected with each other through the first support plate and thus static electricity can be fully discharged, so that the foldable display can be protected from being damaged by ESD.
