Functional membrane, mobile terminal, hot pressing molding method of functional membrane and tool for hot pressing molding

Abstract

The invention relates to a functional membrane, a mobile terminal, a hot pressing molding method of the functional membrane and a tool for hot pressing molding. The functional membrane is applied to a curved surface cover plate and is provided with a shading region and a light transmitting region, one surface of the cover plate back to a user is the back surface of the cover plate, when the functional membrane is attached to the back surface of the cover plate, the region, corresponding to the shading region, on the cover plate forms a non-display region, the region, corresponding to the light transmitting region, on the cover plate forms a display region, and the shape of the functional membrane is matched with the shape of the back surface of the cover plate. The mobile terminal applies the functional membrane above. The hot pressing molding method of the functional membrane is used to manufacture the functional membrane. The tool for hot pressing molding is used to implement the hot pressing molding method of the functional membrane. The functional membrane is prefabricated into a curved surface model suitable for the curved surface cover plate before attaching, which is favorable for solving the defect problem occurring when a flat functional membrane is attached, such that the attaching yield and finished product quality are improved.

Description

technical field [0001] The invention relates to a functional diaphragm, a mobile terminal, a hot pressing forming method of the functional diaphragm and a tool for hot pressing forming. Background technique [0002] With the application of flexible display screens on mobile terminals, the design of the glass cover plate of the display screen is gradually changing from flat to non-curved. For the curved glass cover, in addition to the complex molding process compared with the flat glass cover, the subsequent coloring (to form the display area and the non-display area) process is also very difficult. At present, the commonly used solution is to stick a functional film (i.e. color film) on the back of the glass cover (and the side facing away from the user). The light-shielding ink layer is then cut into appropriate size specifications, and then the planar functional film is pasted on the back of the cover plate using laminating technology. [0003] Since the functional diaph...

Problems solved by technology

[0004] In order to overcome the problem of affecting the quality of finished products in the prior art, the embodiment of the present invention provides a functional diaphragm on the one hand, which is applied to a curved cover plate. The functional diaphragm is provided with a light-shielding area and a light-transmitting area. The cover plate The side facing away from the user is the back of the cover. When the functional film is attached to the back of the cover, the area on the cover corresponding to the light-shielding area forms a non-display area, and the area on the cover corresponding to the light-transmitting area forms a non-display area. Form a display area, characterized in that the shape of the functional membrane matches the shape of the back of the cover plate
