Detailed Description
Reference will now be made in detail to the exemplary embodiments, examples of which are illustrated in the accompanying drawings. When the following description refers to the accompanying drawings, like numbers in different drawings represent the same or similar elements unless otherwise indicated. The embodiments described in the following exemplary embodiments do not represent all embodiments consistent with the present invention. Rather, they are merely examples of apparatus and methods consistent with certain aspects of the invention, as detailed in the appended claims.
As display technology advances, terminal screens are evolving from LCDs to OLEDs. Meanwhile, the screen is also ultrathin. The ultra-thin screen design inevitably weakens the strength of the screen, and causes easy stress and fracture.
In view of this, the present disclosure provides a display screen manufacturing method for forming a display screen having a buffer layer.

When the display panel is a panel with two display surfaces, the transparent cover plate is attached to one of the display surfaces, and the buffer layer is attached to the opposite surface of the display surface. The display panel includes, but is not limited to, an OLED display panel. The transparent cover plate may be, but is not limited to, a glass cover plate.
According to the display screen manufacturing method provided by the embodiment of the disclosure, the transparent cover plate is firstly attached to the display panel, and then the buffer layer is attached to the opposite surface of the display panel, which is attached to the transparent cover plate, so that when the transparent cover plate is pressed in the whole process, the buffer layer and the display panel do not need to be pressed together with the transparent cover plate in the vacuum chamber, and only the display panel and the transparent cover plate need to be pressed together in the vacuum chamber, so that the problem that marks are left on the display panel due to stress when the buffer layer is pressed together is avoided.
Meanwhile, the display screen is formed to have a buffer layer. The buffer layer can be a buffer structure with certain elasticity and certain strength, and can be used for buffering the stress on the opposite surface of the display panel to play a role in protecting the display panel. Particularly, the buffer layer has obvious buffer protection effect on the ultrathin and fragile OLED display screen with a large display surface. Especially, the device installation space in the terminal is limited, and when the opposite surface of the display panel is in direct contact with other devices in the terminal, the device installation space is beneficial to relieving the force action of the other devices on the display panel, and the phenomenon of fragmentation caused by the fact that the force action directly acts on the display panel is reduced.
In some embodiments, the attaching the transparent cover plate on the display panel includes:
arranging colloid in the peripheral area of the display panel surrounding the display area;

The anisotropic conductive adhesive is characterized in that the Z-axis electrical conduction direction and the resistance characteristics of the XY insulation plane have obvious difference. When the difference between the Z-axis conduction resistance value and the XY-plane insulation resistance value exceeds a certain ratio, it is called as good conduction anisotropy.

When the display panel and the transparent cover plate are pressed, the conductive particles of the conductive film are broken and deformed under the action of specific time, temperature and pressure, so that the positions pressed by the conductive films are conductive, and the positions not pressed by the conductive films are insulating, thereby forming the combination of the IC and the two-side circuit of the glass and the conduction of the circuit.
In some embodiments, the method further comprises:
and bending the part of the circuit extending out of the display panel to the opposite surface of the display panel surface where the circuit is located.
