Abstract
The invention discloses a display panel and a display device, the display panel comprises a normal display area and a fan-out display area, and the fan-out display area comprises a first area and a second area; pixel driving circuit units of the display panel are located in a normal display area and a first area, fan-out wires are located in a second area, and the density of the pixel driving circuit units located in the first area is larger than that of the pixel driving circuit units located in the normal display area. The pixel driving circuit units are electrically connected with the corresponding anodes through connecting wires in the connecting wire layer; the shielding layer is arranged on the side, away from the substrate, of the pixel definition layer, the multiple second openings of the shielding layer correspond to the multiple first openings of the pixel definition layer, light reflected by the metal wires can be shielded, and the visible mura phenomenon in the screen-off and screen-on states can be improved.
Description
technical field [0001] The present invention relates to the field of display technology, and in particular, to a display panel and a display device. Background technique [0002] With the development of OLED panel technology, narrow bezel technology has become a differentiated technology that attracts user groups. As a new layout method, FIAA (FanoutinAA, the fan-out trace is located in the display area) technology can effectively reduce the lower frame of the panel. In FIAA technology, multi-layer connection wiring design is introduced to squeeze out wiring space for fan-out wiring, but in the process of connecting wiring and wiring, due to the limitation of wiring space, it is easy to cause the metal wiring density in the fan-out display area to be different from the normal display area. There are differences in the density of metal traces, which can easily lead to uneven light reflected from the metal traces, resulting in uneven visibility (mura) in the fan-out display a...
