Problems solved by technology

[0004] In the display device provided by the prior art, the pads 021 have the same size and the same resistance; the lengths of the multiple signal lines 022 are not completely the same, so the resistances of the multiple signal lines 022 are not completely the same, so the electrical output from the chip 03 The voltage drop of the signal after passing through different signal lines 022 and pads 021 is different, and after being transmitted to the display panel 01, it causes uneven display on the display panel 01 and reduces the display quality

Abstract

The invention discloses a display device, and belongs to the technical field of display. The display device comprises a display panel, chips and a flexible printed circuit board; the flexible printed circuit board comprises multiple first signal lines and multiple conductive pads which are arranged in one-to-one correspondence; the conductive pads are electrically connected with the display panel; one end of each first signal line is electrically connected with the corresponding conductive pad, and the other end of each first signal line is electrically connected with the corresponding chip; the lengths of the multiple first signal lines are not exactly the same; resistances of the multiple conductive pads are not exactly the same; the resistance of the conductive pad arranged corresponding to the long first signal line is smaller than that of the conductive pad arranged corresponding to the short first signal line. Compared with the prior art, non-uniform display is relieved, and the display quality is improved.

Description

technical field [0001] The present invention relates to the field of display technology, and more specifically, to a display device. Background technique [0002] With the development of display technology, consumers have more and more diverse demands on display devices. The display device with a narrow frame has the advantages of portability and aesthetics, and is favored by consumers. In the display device provided by the prior art, COF (Chip On FPC) technology is used to reduce the width of the frame. [0003] Please refer to figure 1 , figure 1 It is a schematic plan view of a display device provided in the prior art. figure 1 The shown display device includes a display panel 01 and a flexible circuit board 02 . The display device further includes a chip 03 for processing electrical signals in the display panel 01 . In order to reduce the area occupied by the chip 03 on the display panel 01 , the chip 03 is arranged on the flexible circuit board 02 . The flexible ...
