Example 1
The embodiment specifically discloses a foldable UTG display screen, and aims to ensure that the display screen can ensure the sense of a user when being folded and also can give consideration to the convenience and easiness of folding through the optimization and improvement of the display screen, so that the defect of crease at the folding position is reduced or even eliminated.
As shown in fig. 1, the display screen is designed as follows:
the ultra-thin glass and the flexible screen are arranged in a parallel mode, the ultra-thin glass and the flexible screen are arranged on the same folding symmetrical plane, optical cement is filled in the space between the ultra-thin glass and the flexible screen, the optical cement is OCA optical cement, and the ultra-thin glass is UTG ultra-thin glass.
And two supporting cover plates are symmetrically arranged on two sides of the folding symmetrical plane and positioned in the OCA optical cement between the ultrathin glass and the flexible screen, so that the electronic display screen is formed by the supporting cover plates, UTG ultrathin glass and the flexible screen. The OCA optical cement filled between the two support cover plates forms a bending area, the support cover plates can be freely folded through the bending area, and the support cover plates, the ultrathin glass and the flexible screen are matched in shape. In practical application, the two supporting cover plates are respectively bonded with the UTG ultrathin glass through optical cement to form a cover plate assembly, and the cover plate assembly is bonded with the flexible screen through the optical cement to form the electronic display screen. The size of the bending region is determined by an R angle of UTG ultrathin glass during bending, and the larger the R angle is, the larger the size of the bending region is, namely, the larger the distance between two supporting cover plates is (for example, when the electronic display screen is in an outward folding design); conversely, the smaller the R angle, the smaller the size of the bending region, i.e. the smaller the distance between the two supporting cover plates (for example, when the electronic display screen is designed to be folded inwards).
In this embodiment, the supporting cover plate, UTG ultra-thin glass and flexible screen in the electronic display screen are all set as straight plate segments, and the supporting cover plate is a glass cover plate, for example: the glass cover plate can be used for vehicle-mounted large-screen display or life large-scale electronic display. When specifically using, support the apron and do the bending motion under the exogenic action, its specific theory of operation as follows:
in use, the supporting cover plate is subjected to external forces, such as: when being applied to folding cell-phone, this support apron then can receive the effort of the hinge mechanism, and support the apron when the motion, its linkage adhesion produces deformation in outside OCA optical cement, and then at folding in-process, OCA optical cement is real-time to be deformed in order to produce good supporting effect to the part of bending of flexible screen, through supporting the apron to both sides tensile give the even tensile force of the flexible screen of benefit position of bending, more can guarantee to level and smooth, can effectively alleviate the crease defect.
In practical application, for ensuring that the supporting force provided by the supporting cover plate linkage OCA optical cement is uniform and stable, when the electronic display screen is in a completely folded state (folded by 180 degrees), the tangent line of UTG ultrathin glass (the intersection line of the bending section of UTG ultrathin glass and the straight line segment), the end face of the supporting cover plate and the tangent line of the flexible screen (the intersection line of the bending section of the flexible screen and the straight line segment) are located on the same straight line.
The display screen suitable for the foldable UTG provided based on the embodiment has the advantages that:
the method is beneficial to reducing or even eliminating the crease defect at the folding position: because the supporting cover plate is a glass cover plate, when acting force (such as a hinge mechanism) is applied to the outside, only about 20% of the area (namely the finger bending area) in the middle is a flexible area when the supporting cover plate is unfolded, the supporting cover plate can be stretched to two sides to provide uniform tensile force for bending the position-compensating screen, the flatness can be ensured, and the crease defect can be effectively reduced.
Example 2
On the basis of embodiment 1, the display screen suitable for foldable UTG provided by this embodiment is optimized as follows:
as shown in fig. 2 and 3, the supporting cover plate, the ultrathin glass and the flexible screen are arranged to be composed of the straight plate section and the 3D curved surface section together, the 3D curved surface section is located on the side portion far away from the folding symmetrical plane, the 3D curved surface section is arranged on the side portion of the supporting cover plate, the ultrathin glass and the flexible screen, the bending height of the 3D curved surface section is set to be 3-6 mm, and the electronic display screen formed by the supporting cover plate, the ultrathin glass and the flexible screen has good 3D visual sense. The glass cover plate can be used for various special-shaped large-curved-surface screens, the whole glass cover plate of the special-shaped large-curved-surface screen cannot be processed, the glass cover plates can be spliced through the single glass cover plate, the curved-surface screen where the single glass cover plate is located can play a supporting role, smooth connection of curved surfaces can be guaranteed, the cost is reduced, and the problem that the glass cover plate cannot be manufactured is solved.
In this embodiment, the lateral part that will support apron, ultra-thin glass and flexible screen all establishes to 3D curved surface section's advantage lies in:
the display screen is a 3D curved surface display screen when being unfolded for use, and can better accord with the current aesthetic trend and generate good visual effect.
Secondly, the curved surface sense is ensured, and the folding convenience and easiness are also considered: when the mobile phone display device is applied to a mobile phone, curved surface display on two sides is expanded, a display area is larger, a flat display space can be achieved, the mobile phone is only large and wide after being folded, the mobile phone display device is convenient to carry, a larger window effect can be ensured during operation, and good entertainment and office experience is brought;
increasing the surface flatness of the curved screen: because the left supporting cover plate and the right supporting cover plate are arranged, the display area is occupied by more than 80%, the supporting cover plates provide supporting acting force, the display smoothness of the curved surface form can be effectively guaranteed, and the defect that display distortion is corrugated due to deformation caused by touch extrusion is avoided.
Example 3
On the basis of embodiment 1, the display screen suitable for foldable UTG provided by this embodiment is optimized as follows:
will support apron, ultra-thin glass and flexible screen and all set up to 3D curved surface section, the bending height of 3D curved surface section can freely be set for according to actual conditions to provide the supporting force by supporting the apron, this design can be applied to bracelet class electronic display, can make two semicircle forms of folding plane of symmetry both sides show seamless connection, but satisfy the demand that the lock was dressed.
The utility model is not limited to the above alternative embodiments, and any other various forms of products can be obtained by anyone in the light of the present invention, but any changes in shape or structure thereof, which fall within the scope of the present invention as defined in the claims, fall within the scope of the present invention.
