Abstract

The present invention provides a drive circuit and a display device. The drive circuit comprises a drive chip used for providing a drive signal; at least two strip-shaped fan-out parts used for transmitting the drive signal to the display region of the display panel, wherein each strip-shaped fan-out part is composed of a first metal layer and a second metal layer and the second metal layer is located on the first metal layer. The width of the second metal layer is smaller than the width of the first metal layer. According to the technical scheme of the drive circuit and the display device, the power consumption can be reduced.

Description

[0001] 【Technical field】 [0002] The invention relates to the technical field of displays, in particular to a driving circuit and a display device. [0003] 【Background technique】 [0004] With the continuous development of the display panel, the driving technology for the display panel is also continuously developed. Existing display panels generally include an array substrate and a color filter substrate. A plurality of data lines, a plurality of scan lines and a plurality of pixel units defined by the data lines and the scan lines are arranged on the array substrate. [0005] In order to drive the display panel, generally a driver chip is disposed on the periphery of the display panel, that is, the driver chip is located in a non-display area. The driving chip is used for providing driving signals, and the driving signals include data signals and scanning signals. The driving chip is connected to the scanning line and the data line through the fan-out line, so as to tran...
