Abstract

A display panel and a display device. The display panel includes at least two controlled modules and a signal wire connected to the at least two controlled modules. The signal wire is configured to receive a drive signal sent by a drive module and transmit the drive signal to the at least two controlled modules. The signal wire includes a first path wire section and a second path wire section. A first end of the first path wire section and a first end of the second path wire section are configured to receive the same drive signal. The first path wire section is configured to sequentially transmit the drive signal to the at least two controlled modules in a first preset sequence. The second path wire section is configured to sequentially transmit the drive signal to the at least two controlled modules in a second preset sequence.
