The invention discloses a display panel, a
display device and a display terminal, and the display panel comprises an array substrate which comprises a light-emitting side and a backlight side which is oppositely arranged; the wiring layer is located on the backlight side of the array substrate, and the wiring layer comprises at least one
signal line; the at least one pixel circuit is located on the side, away from the wiring layer, of the array substrate, and the
signal line at least penetrates through part of the array substrate and is connected with the pixel circuit
signal line. According to the array substrate, the wiring layer is arranged on the backlight side of the array substrate, the
signal lines located on the wiring layer and the pixel circuit
signal lines are arranged along the two sides of the array substrate respectively,
direct coupling between the
signal lines is avoided, and therefore
coupling capacitance or mutual
inductance is reduced. According to the technical scheme provided by the invention, the problem of non-uniform display caused by signal attenuation and
signal delay during signal transmission of a large-size
OLED display screen in related technologies is solved, the quality of a display picture is improved, and further, the application of an
OLED display product in the field of large-size display is facilitated.
