Molding a display screen into a housing of an electronic device
View Patent ↗Arrangements described herein relate to molding of a display screen into a housing of an electronic device. Ad adhesive can be applied to a side of a plastic film to form an adhesion member. The adhesion member can be connected to the display screen, the adhesive bonding to the plastic film to a peripheral region of the display screen. The display screen with the connected adhesion member can be inserted into a housing mold. Plastic resin can be injected into the housing mold to form a housing of the electronic device, the plastic film bonding with the injected plastic resin to secure the display screen into the housing.
1. A method of molding a display screen into a housing of an electronic device, the method comprising:
applying an adhesive to a first side of a plastic film to form an adhesion member, the plastic film comprising the first side and a second side opposite of the first side;
connecting the adhesion member to the display screen, the adhesive bonding the plastic film to a peripheral region of the display screen;
inserting the display screen with the connected adhesion member into a housing mold; and
injecting plastic resin into the housing mold to form the housing, the plastic film bonding with the injected plastic resin to bond the plastic film to the housing and securing the display screen into the housing.
2. The method of claim 1 , further comprising:
die cutting the adhesion member to a shape that conforms to the peripheral region of the display screen after the adhesive is applied to the first side of the plastic film.
3. The method of claim 1 , further comprising:
die cutting the plastic film to a shape that conforms to the peripheral region of the display screen;
wherein applying an adhesive to the first side of the plastic film to form the adhesion member comprises applying the adhesive to the first side of the die cut plastic film.
4. The method of claim 3 , further comprising:
die cutting the adhesive to the shape that conforms to the peripheral region of the display screen.
5. The method of claim 1 , wherein applying the adhesive to the first side of the plastic film to form the adhesion member comprises spraying the adhesive onto the first side of the plastic film.
6. The method of claim 1 , wherein applying the adhesive to the first side of the plastic film to form the adhesion member comprises dispensing the adhesive onto the first side of the plastic film.
7. The method of claim 1 , wherein the plastic film is a polycarbonate film.
8. The method of claim 1 , wherein:
injecting the plastic resin into the housing mold comprises injecting the plastic resin at a temperature between 150° C. and 350° C.; and
the plastic film at least partially melts at the temperature between 150° C. and 350° C., creating a bond between the plastic film and the housing when the plastic film and plastic resin cool to a temperature where the plastic resin is hardened to form the housing.
9. An electronic device, comprising:
a device housing;
an adhesion member comprising:
a plastic film comprising a first side and a second side opposite of the first side; and
an adhesive applied to the first side of the plastic film;
a display screen molded into an aperture of the device housing during a plastic injection molding process forming the device housing from plastic resin injected into a housing mold, the adhesive applied to the first side of the plastic film bonding the plastic film to a peripheral region of the display screen, and the plastic film bonding with the injected plastic resin to bond the plastic film to the device housing and secure the display screen into the device housing.
10. The electronic device of claim 9 , wherein the adhesion member is die cut to a shape that conforms to the peripheral region of the display screen after the adhesive is applied to the first side of the plastic film.
11. The electronic device of claim 9 , wherein the plastic film is die cut to a shape that conforms to the peripheral region of the display screen, and the adhesive is applied to the first side of the die cut plastic film.
12. The electronic device of claim 11 , wherein the adhesive is die cut to the shape that conforms to the peripheral region of the display screen.
13. The electronic device of claim 9 , wherein the adhesive is sprayed onto the first side of the plastic film.
14. The electronic device of claim 9 , wherein the adhesive is dispensed onto the first side of the plastic film.
15. The electronic device of claim 9 , wherein the plastic film is a polycarbonate film.
16. The electronic device of claim 9 , wherein:
the plastic resin is injected into the housing mold at a temperature between 150° C. and 350° C.; and
the plastic film at least partially melts at the temperature between 150° C. and 350° C., creating a bond between the plastic film and the device housing when the plastic film and plastic resin cool to a temperature where the plastic resin is hardened to form the device housing.
