Abstract:
1. A driver IC chip mounted to a liquid crystal display panel included in a liquid crystal display, wherein the liquid crystal display also comprises a power supply and a timing controller, the driver IC chip comprising: first, second, third, and fourth power pad sections placed at respective four corners of upper and lower side edges of the driver IC chip, wherein each of the first, second, third, and fourth power pad sections comprises a first power pad configured to supply first power to the driver IC chip from the power supply, a second power pad configured to supply second power to the driver IC chip from the power supply, a third power pad configured to supply third power to the driver IC chip from the power supply, and a fourth power pad configured to supply fourth power to the driver IC chip from the power supply, wherein each of the first, second, third, and fourth power pads is connected to the power supply via one or more power supply lines; an input pad section comprising one or more input pads, wherein the one or more input pads are connected to the timing controller via one or more signal lines, wherein the one or more input pads are configured to receive one or more control signals from the timing controller via the one or more signal lines, and wherein the input pad section is placed on the upper side edge of the driver IC chip between the first power pad section and the second power pad section; and an output pad section comprising one or more output pads, wherein the one or more output pads are connected to the liquid crystal display panel via one or more connection lines, wherein the one or more output pads are configured to output one or more signals to the liquid crystal display panel via the one or more connection lines, and wherein the output pad section is placed on the lower side edge of the driver IC chip between the third power pad section and the fourth power pad section, wherein an additional power pad section is placed in at least one of left or right end portions of the driver IC chip, and wherein the upper and lower side edges are longer than the left and right end portions, wherein the first corner of the driver IC chip is positioned at the left end portion of the upper side edge, wherein the second corner of the driver IC chip is positioned at the right end portion of the upper side edge, wherein the third corner of the driver IC chip is positioned at the left end portion of the lower side edge, and wherein the fourth corner of the driver IC chip is positioned at the right end portion of the lower side edge.
