Abstract
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.

A method of removing a protective glass top surface from a display unit having a glass top, an electronic display portion, and a planar intermediate layer 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;
- and
- advancing the cutting device into the intermediate layer to separate the glass top from the electronic display portion.

- fixing the display unit in a carriage with the intermediate layer being exposed on all sides;
- aligning a cutting wire in a coplanar relationship with the intermediate layer;
- biasing the cutting wire in the intermediate layer immediately adjacent the electronic display portion and away from the glass by locating the guide path of the wire below the display;
- driving the cutting wire into the intermediate layer while moving it reciprocally therethrough so that the cutting device and display unit are moved relative to each other along an axis generally orthogonal to the cutting wire;
- and
- advancing the cutting wire into the intermediate layer to separate the glass top from the electronic display portion.
