Problems solved by technology

[0003] However, due to the dense setting of the lower frame circuit, the line width of the non-display area will be compressed to a small size, which will increase the resistance of the line, resulting in an increase in the load and parasitic capacitance caused by the line itself, which is not conducive to signal control.

Abstract

The invention discloses a display panel and a display device, comprising: a multiplexing circuit, a plurality of signal connection lines, and a plurality of data signal lines; each switch unit in the multiplexing circuit includes at least one thin film transistor; Each pixel unit in the first pixel unit column has the same color, and at least two pixel units in the second pixel unit column have different colors; the first switch unit corresponds to the first pixel unit column, and the second switch unit corresponds to the second pixel unit Column correspondence; the equivalent channel width-to-length ratio of the thin film transistor in the first switch unit is smaller than the equivalent channel width-to-length ratio of the thin film transistor in the second switch unit; so that the first switch unit does not affect the normal operation of the first pixel unit column Under the premise of image display, the response speed to signal switching is appropriately reduced, thereby saving the space occupied by the first switch unit, and the saved space is used for the wiring of adjacent signal lines, thereby increasing the area of ​​the signal line. Reduce the resistance of the signal line itself.

Description

technical field [0001] The present invention relates to the field of display technology, in particular to a display panel and a display device. Background technique [0002] As users have higher and higher requirements for the display effect of display screens, display screens with narrow borders and high screen-to-body ratio are becoming more and more popular. In order to reduce the width of the lower frame of the display screen, a multiplexing circuit is arranged in the non-display area of ​​the lower frame of the display screen. The multiplexing circuit can control the charging of different data signal lines, while reducing the number of fan-out lines, thereby reducing the step space occupied by the fan-out lines, so as to reduce the lower frame of the display screen and achieve a higher screen. possession ratio. [0003] However, due to the dense arrangement of the lower frame circuit, the line width of the traces in the non-display area will be compressed to a very sm...
