The laminating frock includes laminating tool 5, elasticity PAD4, year membrane 2 and year membrane anchor clamps 3, year membrane anchor clamps 3 press from both sides tight year membrane 2 both sides and make its middle part laminate mutually with the top surface of elasticity PAD4, elasticity PAD4 is installed on laminating tool 5.

The curved surface is an arc-shaped curved surface with a high middle part and two low sides, the curved surface is pressed against curved glass in the attaching process to generate deformation matched with the curved glass, and the avoiding grooves 42 are positioned at the upper parts of the two side surfaces of the base part 44 to allow the film-carrying clamp 3 to extend into the avoiding grooves. The escape groove 42 has an arc-shaped cross section, and extends in the longitudinal direction of the base 44 and penetrates the front and rear side surfaces. The width of the base part 44 is not larger than that of the pressing part 41, and the lower end of the base part 44 is installed inside the attaching jig 5 and moves upward and downward together with the attaching jig 5 when the screen assembly 1 is attached.

In addition, it should be noted that the avoidance grooves 42 formed on both sides of the elastic PAD4 can reduce the strength of the elastic PAD4 on both sides, and both sides of the curved surface will be recessed into the avoidance grooves 42 during the fitting process to adapt to the curvature of the curved portion of the curved glass.

As shown in fig. 1 and 2, the left and right sides of the carrier film 2 are respectively provided with an extension portion for clamping by a clamp, the carrier film clamp 3 is a horizontal clamping clamp, and includes an upper clamp plate and a lower clamp plate, a horizontal gap is formed between the upper clamp plate and the lower clamp plate, the carrier film 2 is clamped in the horizontal gap, the horizontal clamping clamp clamps the extension portion of the carrier film 2, and stretches towards the avoiding groove 42 to straighten the carrier film 2 so that the middle portion of the carrier film 2 is in curved surface fit with the top pressing portion 41 of the elastic PAD4, the elastic PAD4 and the carrier film clamp 3 can move upwards and downwards simultaneously during the fitting, so that the carrier film 2 forms a shape adapted to the curved glass, and the carrier film 2 is always fitted with the curved surface of the top pressing portion 41 of the elastic body during the fitting process to provide sufficient supporting force for the curved display module.
