摘要： An overdrive topology structure for transmission of a RGB signal includes a signal sending terminal, a signal receiving terminal, and a transmission line to transmit the RGB signal from the signal sending terminal to the signal receiving terminal. The transmission line is divided into a number of section transmission lines. A node is formed between every two section transmission lines. An impedance of a first section transmission line approaching to the signal sending terminal is less than an impedance of a second section transmission line approaching to the first section transmission line to overdrive the RGB signal at a first node between the first and second section transmission lines. At least one node except the first node is grounded via a resistor. An equivalent resistance of the resistor is equal to a resistance of the first resistor.

摘要： A printed circuit board includes a plurality of differential pairs arranged thereon side-by-side. Each differential pair includes two transmission lines. Each transmission line includes a plurality of sections of equal length. Every two adjacent sections in each transmission line meet at an angle, and all angles are equal. The length of each section is determined by dividing the distance between two corresponding angles of the two transmission lines of each differential pair by the cosine of half of the angle.
