Abstract
An active matrix of a display panel having a plurality of array elements and at least two data busses, each array element including a primary switch initially connected to the data busses and at least one connectable secondary switch, wherein, when the primary switch is disconnected from the busses, one of the at least one secondary switches is connected to the busses.
Claims10
An active matrix of a display panel having a plurality of array elements and at least two data busses, each array element comprising:
- a primary switch initially connected to said data busses;
- at least one connectable secondary switch, wherein, when said primary switch is disconnected from said busses, one of said at least one secondary switches is connected to said busses;
- and
- a fuse between said primary switch and each of said data busses;
- and
- wherein said at least one secondary switch is connected to said data busses by normally open links;
- and
- wherein said links comprise an insulator located between two, partially overlapping, metal branches, and
- wherein said two metal branches comprise an upper and a lower branch and wherein said upper branch has an opening exposing said insulator.
An active matrix of a display panel having a plurality of array elements and at least two data busses, each array element comprising:
- a primary switch initially connected to said data busses;
- a fuse between said primary switch and each of said data busses;
- and
- at least one connectable secondary switch, wherein, when said primary switch is disconnected from said busses, one of said at least one secondary switches is connected to said busses,
- wherein said at least one secondary switch is connected to said data busses by normally open links,
- and wherein said links comprise a thin film connecting two metal strips, and
- wherein said thin film comprises first and second sections of a first polarity between which is a third section of a second polarity, wherein, upon irradiation by a laser, said second polarity of a portion of said third section is changed to said first polarity.
