Abstract
The present invention discloses a display panel, a chip and a flexible circuit board. The display panel includes a panel body and at least two signal transmission circuits. The signal transmission circuit includes a line input terminal used for binding to a flexible circuit board, which is disposed at the peripheral area, a signal transmission line, and a line output terminal used for binding to a chip, which is disposed at the peripheral area. At least two of the line output terminals are arranged in a two-dimensional array. The present invention can reduce the impedance of a part of the signal transmission line.
Claims20
A display panel, comprising:
- a panel body, the panel body comprising a display area and a peripheral area disposed on at least one side of the display area;
- a flexible circuit board comprising a horizontal portion and a vertical portion protruding from an end of the horizontal portion in a direction crossing the horizontal portion, wherein the horizontal portion and the peripheral area are spaced apart from each other, and the vertical portion extends toward the peripheral area and to overlap the peripheral area;
- a chip disposed at the peripheral area and between the horizontal portion and the display area, wherein the chip comprises a first side facing the horizontal portion and a second side crossing the first side and facing the vertical portion;
- and
- at least two signal transmission wiring portions disposed at the peripheral area and connecting the flexible circuit board and the chip, wherein each of the at least two signal transmission wiring portions comprises a line input terminal, a line output terminal, and a signal transmission line between the line input terminal and the line output terminal, the line input terminal is bonded to the vertical portion, and the line output terminal is bonded to the second side of the chip, wherein two ends of the signal transmission line are electrically connected to the line input terminal and the line output terminal respectively;
- wherein at least two line output terminals of the at least two signal transmission portions are arranged in a two-dimensional array, and at least two line input terminals of the at least two signal transmission portions are arranged in a one-dimensional array.
