Driving backboard and display device

Abstract

The invention discloses a driving backboard and a display device, and the driving backboard comprises a substrate, a plurality of signal lines arranged on the substrate, a plurality of binding electrodes, and a plurality of connecting lines. At least one of the multiple signal lines extends in the first direction, the first end of any one of the multiple connecting lines is electrically connected with at least one of the multiple binding electrodes, and the second end of any one of the multiple connecting lines is electrically connected with one of the multiple signal lines; the line width of at least one connecting line in the plurality of connecting lines at the first end is smaller than the line width at the second end; at least one of the connecting lines comprises a first straight line part extending in the first direction and an oblique line part with a certain included angle between the extending direction and the first direction; one end of the first linear part is electrically connected with the binding electrode; the other end of the first straight line part is electrically connected with the signal line through the oblique line part. According to the driving backboard, the wiring space can be fully utilized, the area of a fan-out area is reduced, and the wiring difficulty of signal lines is reduced.

Description

[0001] Cross-reference related application [0002] The present application requires the provision of China's patent bureau from September 24, 2020, and the application number is 20,201,017476.8, the application name is "a driving backplane and display device" priority, and the entire content is incorporated herein by reference. middle. Technical field [0003] The present invention relates to the field of display, especially in a driving back panel and a display device. Background technique [0004] With the development of Light Emitting Diode, LEDs, microfluonden-emitting diode display technology will become a revolutionary technology, microfluidization diodes are minimally and matrix of traditional LED structures, and use integrated circuits. The process is made to drive the backplane to achieve each pixel point address control and separately driven display technology. [0005] For microfluonden-emitting diode display devices, since the line width of the signal line in the dri...
