a driver circuit board;

a plurality of gate driver chips connected to the driver circuit board;

a connecting line connecting the driver circuit board to the plurality of gate driver chips and configured to transmit signals to the plurality of gate driver chips;

a plurality of fanout cables, each of which being connect the respective gate driver chip to a respective gate line of a display panel, wherein the fanout cables that are connected to each gate driver chip form a fanout region thus resulting in a plurality of fanout regions disposed in one-to-one correspondence with the plurality of gate driver chips, wherein the plurality of fanout regions are arranged along a transmission direction of the signals, wherein the signals are transmitted from a previous gate driver chip to a next gate driver chip; and

a plurality of additional conductive films arranged in one-to-one correspondence in the plurality of fanout regions, wherein the plurality of additional conductive films disposed in different fanout regions have different areas, and wherein a total overlapping area between a respective additional conductive film and all the fanout cables of each of the plurality of fanout regions decreases from one fanout region to next fanout region in a single direction along the transmission direction of the signals and wherein the total overlapping area is covered by a shape the respective additional conductive film.
