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:
- securing the display unit to a carrier 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 adjacent the electronic display portion and away from the glass;
- driving the cutting wire into the intermediate layer while moving the cutting wire and display unit 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.
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:
- securing the display unit in a carrier 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 adjacent the electronic display portion and away from the glass wherein said biasing is accomplished by locating the guide path of the wire towards the electronic display portion and away from the glass;
- driving the cutting wire into the intermediate layer while moving the cutting wire and display unit relative to each other along an axis generally orthogonal to the cutting wire;
- moving the cutting wire reciprocally relative to the display unit while the cutting wire is driven into the intermediate layer;
- and
- advancing the cutting wire into the intermediate layer to separate the glass top from the electronic display portion wherein said advancing is performed during said biasing.
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:
- securing the display unit in a carrier with the intermediate layer being exposed on all sides;
- aligning a cutting device in a coplanar relationship with the intermediate layer;
- 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;
- biasing the cutting device in the intermediate layer adjacent the electronic display portion and away from the glass;
- and
- advancing the cutting device through the intermediate layer to separate the glass top from the electronic display portion.
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:
- securing 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;
- 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;
- biasing the cutting device in the intermediate layer adjacent the electronic display portion and away from the glass wherein said biasing is accomplished by locating the guide path of the cutting device towards the electronic display portion and away from the glass;
- moving the cutting device reciprocally relative to the display unit while the cutting device is driven into the intermediate layer;
- and
- advancing the cutting device into the intermediate layer to separate the glass top from the electronic display portion wherein said advancing is performed during said biasing.
