Abstract
Abstract Peripheral electrodes formed at the same time as the electrode arrays of a display panel and surrounding each array are cut into at least two segments. Two cut electrodes can thus be repaired together with each peripheral electrode by applying conductive deposits which serve to join the ends of each cut electrode to a peripheral electrode segment.

Claims Analysis
Total Claims: 14
Claim 1
Independent Claim
86 words
A method for repairing cut electrodes of a display panel having two arrays of said electrodes formed on both faces of the panel, said electrodes supplied at one end, wherein said method comprises the following steps: forming at least one peripheral electrode on each face of the panel surrounding each array of electrodes, and cutting said peripheral electrode to obtain peripheral electrode segments; connecting both ends of a cut electrode of one array of electrodes to a peripheral electrode segment by means of a conductive deposit.
Claim 2
Independent Claim
86 words
A method for repairing cut electrodes of a display panel having two arrays of said electrodes formed on both faces of the panel, said electrodes supplied at one end, wherein said method comprises the following steps: forming at least one peripheral electrode on each face of the panel surrounding each array of electrodes, and cutting said peripheral electrode to obtain peripheral electrode segments; connecting both ends of a cut electrode of one array of electrodes to a peripheral electrode segment by means of a conductive deposit.
Claim 3
Dependent Claim
29 words
A method according to claim 1, wherein the peripheral electrode surrounding the array of electrodes is formed at the same time as the two electrode arrays of the panel.
Claim 4
Dependent Claim
18 words
A method according to claim 1, wherein the conductive deposit is formed by a deposited silver containing lacquer.
Claim 5
Dependent Claim
15 words
A method according to claim 3, wherein the silver containing lacquer is deposited by hand.
Claim 6
Independent Claim
113 words
A method for repairing cut electrodes of a display panel having two arrays of said electrodes formed on both faces of the panel, said electrodes supplied at one end, wherein said method comprises the following steps: forming at least one peripheral electrode on each face of the panel surrounding each array of electrodes, and cutting said peripheral electrode to obtain peripheral electrode segments; connecting both ends of a cut electrode of one array of electrodes to a peripheral electrode segment by means of a conductive deposit, wherein each end of the electrodes of the arrays is provided with enlarged ends and non-enlarged ends in alternate sequence on each side of the electrode array.
Claim 7
Independent Claim
113 words
A method for repairing cut electrodes of a display panel having two arrays of said electrodes formed on both faces of the panel, said electrodes supplied at one end, wherein said method comprises the following steps: forming at least one peripheral electrode on each face of the panel surrounding each array of electrodes, and cutting said peripheral electrode to obtain peripheral electrode segments; connecting both ends of a cut electrode of one array of electrodes to a peripheral electrode segment by means of a conductive deposit, wherein each end of the electrodes of the arrays is provided with enlarged ends and non-enlarged ends in alternate sequence on each side of the electrode array.
Claim 8
Dependent Claim
38 words
A method according to claim 11, wherein at least one electrode of the arrays has a cut in proximity to the non-enlarged end of said electrode and wherein said cut is repaired by means of a conductive deposit.
Claim 9
Dependent Claim
52 words
A method according to claim 5, wherein each peripheral electrode which surrounds one array of electrodes, is cut so as to obtain at least two electrode segments and both ends of a cut electrode of one array of electrodes are connected to said peripheral electrode segment by means of a conductive deposit.
Claim 10
Dependent Claim
52 words
A method according to claim 6, wherein each peripheral electrode which surrounds one array of electrodes is cut so as to obtain at least two electrode segments and both ends of a cut electrode of one array of electrodes are connected to a peripheral electrode segment by means of a conductive deposit.
Claim 11
Independent Claim
83 words
A method for repairing cut electrodes of a panel having arrays of electrically connected electrodes, wherein said method comprises: forming at least one peripheral electrode on the face of the panel surrounding each array of electrodes, wherein the peripheral electrode surrounding the array of electrodes is co-planar with the electrode arrays of the panel, and cutting said peripheral electrode to obtain peripheral electrode segments; electrically connecting both ends of a cut electrode via a peripheral electrode segment by means of a conductive deposit.
Claim 12
Independent Claim
83 words
A method for repairing cut electrodes of a panel having arrays of electrically connected electrodes, wherein said method comprises: forming at least one peripheral electrode on the face of the panel surrounding each array of electrodes, wherein the peripheral electrode surrounding the array of electrodes is co-planar with the electrode arrays of the panel, and cutting said peripheral electrode to obtain peripheral electrode segments; electrically connecting both ends of a cut electrode via a peripheral electrode segment by means of a conductive deposit.
Claim 13
Dependent Claim
18 words
A method according to claim 9, wherein the conductive deposit is formed by a deposited silver containing lacquer.
Claim 14
Dependent Claim
15 words
A method according to claim 10, wherein the silver containing lacquer is deposited by hand.
