Abstract:
A repairable and scalable filter, a tape line substrate with the filter and a display panel assembly with the tape line substrate are provided to effectively reduce the EMI(Electromagnetic Interference) and to maintain the driving property of a driving driver IC(Integrated Circuit) by mounting the repairable and scalable filter within wiring lines and repairing the filter to have a predetermined inductance corresponding to the generation of the EMI. A base film(161) has a chip mounting member for mounting a semiconductor chip. A wiring pattern(180) is arrayed on the base film. A filter is arrayed on the base film adjacent to the wiring pattern. The filter includes a filter wiring line(210) with the first line width and having the first and second ends. Repair members(220) are arrayed between the first and second ends of the filter wiring line. A filter bank member(230) is connected between the first and second ends of the filter wiring lines and controls the inductance of the filter according to the repair of the repairing member. The repair members have one or more repair patterns with the second line width. The filter bank member includes one or more unit bank filters connected in parallel to the repair patterns of the repair members. The unit filter banks have one of meander, spiral or solenoid shapes.
