Abstract

The invention discloses a display panel and a display device.The display panel comprises a driving backboard and a plurality of display assemblies, each display assembly comprises a first substrate and a plurality of first binding terminals, and the driving backboard comprises a second substrate, a plurality of second binding terminals and a plurality of driving chips; the driving chips are arranged on the side, away from the display assemblies, of the second substrate, the driving chips and the display assemblies are arranged in a one-to-one correspondence mode, each driving chip comprises a plurality of driving terminals, each driving terminal is electrically connected with the corresponding first binding terminal through the corresponding second binding terminal, seamless splicing between the child board and the mother board is achieved, and meanwhile the driving terminals are electrically connected with the corresponding first binding terminals through the corresponding second binding terminals. The resistance drop risk existing in the large-size spliced display panel can be reduced, and the display effect can be improved.

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] With the continuous development of display technology, the application of ultra-large display screens is becoming more and more extensive. Ultra-large display screens can meet people's needs for long-distance viewing and large-scale information display. Due to cost considerations, current super-sized display screens are usually implemented using a splicing technology, that is, multiple sub-display screens are spliced ​​together to form a super-sized display screen. However, when multiple display screens are spliced ​​together, large black splicing gaps will appear at the splicing area, which seriously affects the display quality of super-sized display screens. In order to solve the black splicing gap at the splicing place, a borderless splicing display technology has emerged. Multiple display sub-boards...
