Patent ID: 8493377

Claim:
A display device, comprising: a digital board upon which is formed a video signal processing circuit that generates one screen of image data on the basis of a video signal that is inputted from an input source, and generates a drive signal on the basis of the image data; a source driver board that is connected to the digital board by a signal cable, and upon which is formed a source driver circuit that drives each pixel of a display on the basis of the drive signal inputted from the digital board via the signal cable, thus displaying upon the display an image based upon the image data; a gate driver board that is connected to the source driver board, and upon which is formed a gate driver circuit that drives each pixel of a display on the basis of the drive signal inputted from the digital board via the signal cable and the source driver board; and a power supply board upon which is formed a power supply circuit that produces a power supply voltage from a commercial power supply, wherein the source driver board comprises a first source driver board and a second source driver board, wherein the first source driver board is connected to the second source driver board via a cable, wherein the digital board is connected to the power supply board via a first power supply cable, wherein the first source driver board is connected to the power supply board via a second power supply cable, and wherein the power supply board: supplies the power supply voltage to the digital board via the first power supply cable; supplies the power supply voltage to the first source driver board via the second power supply cable; supplies the power supply voltage to the second source driver board via the first source driver board and the cable; and supplies the power supply voltage to the gate driver board via the second source driver board.
