ABSTRACT:
A liquid crystal display (LCD) panel includes a substrate, a plurality of parallel control lines on the substrate, and a bonding pad area on the substrate having a plurality of bonding pads therein. A respective one of a plurality of interconnecting conductors connect a respective bonding pad of the bonding pad area to a respective one of the plurality of parallel control lines, each of the plurality of interconnecting conductors having a uniform resistance. According to embodiments of the invention, an interconnecting conductor of the plurality of interconnecting conductors may include a material selected to provide the uniform resistance. The interconnecting conductor may include a first portion including a first material having a first resistivity and a second portion including a second material having a second resistivity different from the first resistivity. The first and second portions may have respective first and second lengths selected to provide the uniform resistance. According to other embodiments, an interconnecting conductor of the plurality of interconnecting conductors may have a width selected to provide the uniform resistance. In one embodiment, the plurality of interconnecting conductors have a resistivity per unit length associated therewith and extend from the bonding pad area in a fanned configuration, with the resistivity of the interconnecting conductors increasing toward a medial portion of the fanned configuration. The width of the interconnecting conductors may decrease towards the medial portion of the fanned configuration to produce the desired resistivity. According to other embodiments, an interconnecting conductor of the plurality of interconnecting conductors has a length selected to provide the uniform resistance. In one embodiment, the interconnecting conductor has a serpentine portion to provide the desired length.
