Abstract
The present application provides an organic light emitting diode (OLED) display panel and an OLED device. The OLED display panel includes dummy traces disposed on a side of the anode adjacent to the signal traces. At least one of the fanout traces and at least one of the dummy traces are disposed corresponding to a position where the anode is disposed. Each of the fanout traces passing through each of the subpixels and each of the dummy traces passing through each of the subpixels are both symmetrical about a center of the anode of each of the subpixels, so as to improve uniformity of traces in the display area and improve flatness and symmetry of the anode, thereby improving display defect of the display panel.
