Display apparatus and method for binding the same

A display apparatus, comprising:

• a flexible display panel;
• and
• a chip on film bound on a binding region of the flexible display panel;
• wherein the chip on film has at least two rows of output pads separated from each other, the at least two rows of output pads being arranged along a first direction, and virtual elongation lines of all of the output pads intersect at a same intersection point in a first datum line perpendicular to the first direction, and wherein in a same row of output pads, the farther a distance between the virtual elongation line of the output pad and the first datum line is, the larger an angle between said virtual elongation line and the first datum line becomes;
• wherein the flexible display panel has at least two rows of input pads separated from each other, the at least two rows of input pads being arranged along the first direction, and the input pads are in one to one correspondence with the output pads, and wherein virtual elongation lines of all of the input pads intersect at a same intersection point in a second datum line perpendicular to the first direction, and wherein in a same row of input pads, the farther a distance between the virtual elongation line of the input pad and the second datum line is, the larger an angle between said virtual elongation line of said input pad and the second datum line becomes;
• and
• wherein each one of the output pads is electrically connected to each one of the input pads in one to one correspondence, and the input pads and the output pads that are, in one to one correspondence, electrically connected to each other have the virtual elongation lines at a same angle with respect to a common datum line, the common datum line being composed of the first datum line and the second datum line coinciding with each other.
