Description

Technical Field

[0001] The present invention relates to the technical field of curved screen coating, and in particular to a display screen and a processing device and method thereof. Background Art

[0002] With the development of flexible screens, more and more flexible displays are appearing in display fields, and display panels are also curved, giving birth to a variety of curved display products. This has higher requirements for the manufacturing and bonding of curved cover plates, because for curved displays, conventional structures and processes can no longer meet the requirements, and a new way is needed to bond flexible panels and curved covers. Prior to this bonding, all were flat bonding, and there was no relatively mature curved bonding solution. Directly using a flat method for curved bonding, the bonded products would have relatively large bubbles and wrinkles.

[0003] Therefore, it is urgent to develop a new display screen to solve the above problems. Summary of the invention

[0004] The technical problem to be solved by the present invention is to overcome the deficiencies of the prior art and provide a display screen and a processing device and method thereof.

[0005] In order to achieve the above-mentioned purpose, the technical solution adopted by the present invention is as follows: a display screen includes a face cover and a flexible panel bonded thereto, wherein the flexible panel includes a main panel and at least two strip-shaped side panels integrally connected to the main panel, and the flexible panel is a three-dimensional structure bent into a formed state by the main panel and / or the at least two side panels in an initial state.

[0006] By adopting the above technical solution, the flexible panel is designed as a main panel and two strip-shaped side panels integrally connected to the main panel. When the flexible panel is fitted with the face cover, the main panel and the side panels can respectively fit different areas of the face cover, effectively avoiding the problem of wrinkles and bubbles that are easily generated when the flexible panel is designed as an integral structure and fits with the curved face cover.

[0007] In a further embodiment, the flexible panel is in an initial state before being bent to form the three-dimensional structure, the flexible panel in the initial state is planar, and the at least two side panels extend from the connection portion with the main panel in a direction away from the edge of the main panel.

[0008] By adopting the above technical solution, the flexible panel is initially flat, and can be easily attached to the carrier film and bonded to the cover in batches through the carrier film. At least two side panels extend from the connection part with the main panel in a direction away from the edge of the main panel, which can not only maintain the integral connection between the side panel and the main panel, but also separate the extended part of the side panel from the main panel, so as to reduce the generation of wrinkles during bending.

[0009] In a further solution, the flexible panel is in a formed state after being bent to form the three-dimensional structure, and the formed state is that the main panel and the at least two side panels are surrounded by a truncated cone-like shape.

[0010] By adopting the above technical solution, the main panel and the side panels are enclosed in a truncated cone shape similar to the face cover, so that the flexible panel and the face cover can be fitted more closely and the generation of bubbles and wrinkles can be reduced.

[0011] In a further embodiment, the panel includes a front display area and a side display area, the flexible panel is attached to the inner surface of the face cover, the main panel is in contact with the front display area, and the at least two side panels are in contact with the side display area.

[0012] By adopting the above technical solution, the main panel and the side panel are respectively bonded to the front display area and the side display area, and the flexible panel avoids the large-area curved surface connecting the front display area and the side display area, so that the front display area and the side display area can be bonded to the main panel and the side panel of the flexible panel, which can meet the functional requirements while reducing the generation of wrinkles and bubbles during the bonding process.

[0013] In a further embodiment, a connection portion between the main panel and the at least two side panels abuts against the front display area and / or the side display area.

[0014] By adopting the above technical solution, the main panel and the side panel are connected by the connecting part, and the connecting part is attached to the front display area and / or the side display area. This can not only maintain the connection between the main panel and the side panel, but also drive the side panel to bend to adapt to the curved surface of the side display area through the deformation of the connecting part during the attachment process, thereby ensuring smooth attachment and consistency of position of the side panel and the side display area.

[0015] In a second aspect, a display screen processing device is provided, the processing device comprising:

[0016] A pressing mold, comprising an adsorption platform and a support seat arranged above and below, wherein the adsorption platform is used to fix the face cover, and the support seat is used to combine with the adsorption platform to make the flexible panel change from the initial state to the formed state and adhere to the inner surface of the face cover;

[0017] The clamping assembly is used to fix the carrying film between the adsorption platform and the supporting seat, and the flexible panel is arranged on the carrying film.

[0018] By adopting the above technical solution, the processing device realizes the processing of the display screen through the pressing mold and the clamping assembly, so that the flexible panel is deformed from the initial state to the formed state and fits the inner surface of the cover, reducing the occurrence of defects such as wrinkles and bubbles.

[0019] In combination with the second aspect, a further solution is that the carrier film includes a first carrier film and a second carrier film that are integrally connected and cross-arranged, the first carrier film is connected to the main panel, the second carrier film is connected to the at least two side panels, and the clamping assembly is used to fix the two ends of the first carrier film.

[0020] By adopting the above technical solution, the clamping assembly clamps the first carrier film to fix the main panel carried by the first carrier film, and the second carrier film carries the side panels. The side panels are arranged on the opposite sides of the main panel, so the second carrier film and the first carrier film are arranged crosswise, which can not only make the structural layout more reasonable, but also facilitate the balance of force during the fixing process and reduce the generation of wrinkles.

[0021] In combination with the second aspect, a further solution is that the support seat is provided with an elastic member, and when the flexible panel is attached to the inner surface of the face cover, the elastic member abuts against the flexible panel and deforms to form a balanced fitting force between the flexible panel and the face cover.

[0022] By adopting the above technical solution, the elastic part can be deformed during the bonding process between the flexible panel and the face cover, so that the elastic part and the flexible panel fit more closely and the thrust applied by the elastic part on the flexible panel is more uniform, which is beneficial to reduce the generation of bubbles during the bonding process between the flexible panel and the face cover.

[0023] In combination with the second aspect, in a further solution, the support seat is further provided with an adsorption mechanism, and the adsorption mechanism is used to fix the second carrier film so that the at least two side panels are in contact with the elastic member through the second carrier film.

[0024] By adopting the above technical solution, the adsorption mechanism abuts the side panel against the outer peripheral surface of the elastic member by fixing the second carrier film, so as to facilitate pre-positioning before the flexible panel and the cover are bonded, thereby reducing the poor consistency caused by extrusion deformation and misalignment during the bonding process.

[0025] In a third aspect, a display screen processing method is provided, which is applicable to the display screen processing device described in the second aspect, and comprises the following steps:

[0026] Fixing the side panels: the adsorption mechanism fixes the at least two side panels against the side surfaces of the elastic member by adsorbing the second carrier film;

[0027] Fixing the main panel: the clamping assembly sets the main panel on the upper end of the elastic member by fixing the first carrier film;

[0028] Fixing the surface cover: installing and fixing the surface cover on the adsorption platform;

[0029] Fitting: the adsorption mechanism and the support seat move relatively close to each other, and when the surface cover abuts against the carrier film and / or the flexible panel, the clamping assembly moves away from the adsorption platform and moves close to the support seat at the same time.

[0030] By adopting the above technical solution, the side panels, main panel and face cover are pre-fixed by a specific method. During the bonding process, the clamping assembly moves synchronously in the direction away from the adsorption platform and closer to the support seat as the adsorption mechanism and the support seat approach, so that the tension of the first carrier film remains unchanged, the deformation of the main panel is reduced, and the generation of wrinkles and bubbles during the bonding process is reduced.

[0031] In summary, due to the adoption of the above technical solution, the present invention has the following beneficial effects:

[0032] 1. In the display screen of the present invention, the flexible panel is designed as a main panel and two strip-shaped side panels integrally connected to the main panel. When the flexible panel is fitted with the face cover, the main panel and the side panels can be fitted with different areas of the face cover respectively, effectively avoiding the problem of wrinkles and bubbles easily generated when the flexible panel is designed as an integral structure and fitted with a curved face cover.

[0033] 2. The display screen of the present invention is a three-dimensional structure in a formed state by deforming a flat flexible panel in an initial state, which not only facilitates the automatic lamination of the carrier film, but also reduces the generation of wrinkles and bubbles during the lamination process.

[0034] 3. The display screen processing device of the present invention can ensure the stability of the flexible panel during the film lamination process, and can also ensure the consistency of batch lamination of the display screen, thereby improving production and processing efficiency and reducing manufacturing costs.

[0035] 4. The display screen processing method of the present invention has good consistency in batch production and high production efficiency. BRIEF DESCRIPTION OF THE DRAWINGS

[0064] Embodiment 3

[0065] This embodiment discloses a display screen processing method, which is applicable to the display screen processing device in the second embodiment. The processing method includes the following steps:
