Method and apparatus for display screen shield replacement

摘要

A method and apparatus for replacement of damages display shield (typically glass) covering a display screen on a device, typically a mobile phone. Mobile phones have an electronic display protected by a glass shield. Between the glass and the display is often a plastic polarizing or other intermediary sheet. Removal of a damage glass can be accomplished by cutting thru the polarizer with a moving wire or blade. This separates the glass from the sensitive display and allows replacement of the glass without damaging the more expensive display.

1. A method of removing a protective glass top surface from a display unit having a glass top, an electronic display portion, and an intermediate layer including at least one obstruction therebetween, the method comprising the steps of:
fixing the display unit in a carriage with the intermediate layer being exposed on all sides; aligning a cutting device in a coplanar relationship with the intermediate layer; biasing the cutting device in the intermediate layer adjacent the electronic display portion and away from the glass, driving the cutting device into the intermediate layer while moving the cutting device and display unit relative to each other along an axis generally orthogonal to the cutting device; advancing the cutting device into the intermediate layer to separate the glass top from the electronic display portion; and stopping said advancing when a force sensor detects an encounter between said cutting device and said at least one obstruction.
