Referring to fig. 10, fig. 10 is a schematic structural diagram of a display panel assembly in the conventional technology, and a surround panel structure in the conventional technology is to attach a layer of PI film to a surface layer of a flexible display panel module to form a display panel assembly 001. The whole display screen component 001 is soft and can be bent. The structure realization form of the electronic equipment is that the flexible display screen component 001 is unfolded firstly, the electronic equipment is assembled according to a normal assembly mode, then the display screen component 001 is bent along the appearance of the whole machine, and finally the display screen component 001 is attached to the middle frame 002 of the electronic equipment.

The flexible screen and the PI film are jointed together by OCA (optical clear adhesive) in a planar state. This attachment is the same as conventional screen and cover attachment, i.e., in a flat condition. And wrinkles and air bubbles generated by the bonding between the two materials after the bonding are removed or driven out in a plane pressing and driving mode.

In the surrounding flexible screen structure in the conventional technology, the screen cover plate is made of a PI film. Although the PI film is easily deformed and bent, it is resistant to scratches and poor in impact resistance. In the using process of a user, the problems of scratch and the like can occur quickly, and the user experience and the appearance effect of the mobile phone are influenced. In addition, the PI film material of the screen cover plate structure has obvious difference with a glass cover plate when being viewed from the outside, the glass luster effect of the glass cover plate is not achieved, and the integral appearance expressive force of the electronic equipment is poor.

In comparison, the cover plate structure made of glass material is designed in the embodiment, and the cover plate structure has the characteristics of high strength, good scratch resistance and the like. The assembly method is also completely different from the conventional art. The screen apron that this scheme surrounded the screen is the glass material, consequently can't buckle after the apron shaping is accomplished and warp. After the cover plate is formed, the flexible display screen module is attached to the glass cover plate through OCA glue, and a display screen assembly is formed. It should be noted that all the directional indicators (such as upper, lower, left, right, front and rear … …) in the embodiment of the present invention are only used to explain the relative position relationship between the components, the movement situation, etc. in a specific posture (as shown in the drawing), and if the specific posture is changed, the directional indicator is changed accordingly.

The screen cover plate that encircles the screen among the technical scheme of this application is the glass material, therefore can't buckle after glass cover plate 110 shaping is accomplished and warp. After the glass cover plate 110 is formed, the flexible display screen module 120 is attached to the inner surface of the glass cover plate 110 by OCA glue to form the display screen assembly 100 (see fig. 6 and 7 for details). The difficulty of this process is that after the glass cover plate 110 and the flexible display module 120 are adhered together by OCA glue, because the glass cover plate 110 is not planar and is in a bent state, slight wrinkles and bubbles generated by the adhesion cannot be removed according to the conventional wrinkle and bubble removing process, such as by pressing or driving. And too big power and production too big deformation can not exert to the flexible screen in the laminating process, otherwise the condition that the flexible screen is damaged appears easily, the bad scheduling problem of demonstration appears. The relative position accuracy of screen and glass apron still needs to be guaranteed in the laminating, otherwise the off normal appears, influences the screen and uses and complete machine equipment.

In view of this, the embodiment of the present application provides a method for attaching a display screen assembly, and the scheme mainly solves how to attach a flexible screen in a C-shaped glass cover plate form. This scheme has still designed a laminating tool, laminates flexible display screen and glass apron through this laminating tool. The problem point more than the C type glass apron screen laminating is solved simultaneously.

Step M102, providing a negative pressure to the accommodating space of the attaching jig, so that the flexible display screen (the flexible display screen module 120 in the foregoing embodiment, the same applies below) is adsorbed on the outer surface of the main body portion of the attaching jig.

In this step, this application embodiment still provides a laminating tool, and the main thinking is, does a profile modeling tool, and the tool is middle to be drawn empty, can inhale and blow the action of rising. The outer surface of the jig is provided with holes for the gas to enter and exit. When the air suction action is carried out, the flexible screen is sucked onto the profiling jig, and the flexible screen wraps the profiling jig and is the same as the inner wall of the C-shaped glass cover plate in shape. At the moment, the screen is adsorbed on the jig, and through the positioning structure on the jig, the relative position of the screen and the jig is more accurate. With screen and tool under this state, as an organic whole, fill in C type glass apron in, at this moment, rely on the location structure between tool and the C type glass apron, it is accurate with C type glass apron relative position to adsorb the tool that has the flexible screen. At the moment, the air suction of the jig is changed into air blowing, the air blowing separates the flexible screen from the jig, the OCA of the blown and separated flexible screen is in contact with the inner wall of the C-shaped glass cover plate, and the blown and separated flexible screen and the C-shaped glass cover plate are adhered together after being in contact. Simultaneously, the gas that blows off has an applied power of blowing to the flexible screen back of laminating on glass apron to make the better laminating of flexible screen and C type glass apron inner wall be in the same place, and discharge bubble, and avoid appearing the outward appearance problem that laminating such as fold arouses.
