View Patent ↗A driving circuit of a liquid crystal display panel includes a substrate, a plurality of driver IC chips located on the substrate, a current supplier, and a first conductive wire set. The first conductive wire set has a plurality of conductive wire segments for connecting the driver IC chips in parallel to the current supplier. Furthermore, the conductive wire segments each have a form, such that paths formed of the conductive wire segments from the current supplier to the respective driver IC chips have an equal resistance, and, accordingly, each of the driver IC chips obtain the same input voltage. Hence, a problem of band mura is avoided.
