The utility model provides a transformer coil winding structure and a transformer, and relates to the technical field of transformer coils, the transformer coil winding structure comprises a winding structure, a coil lead and an air passage layer, the coil lead penetrates and is wound above the outer side surface of the winding structure to form a plurality of layers of inner coil structures; the coil leads of the aligned rows of coils in the adjacent layers of inner coil structures are integrally connected and are opposite in winding direction, the air channel layer is combined to the outer side face of the outermost layer of inner coil structure, and the coil leads of the last row of coils in the outermost layer of inner coil structure penetrate through the air channel layer and are wound on the outer side face of the air channel to form a plurality of layers of outer coil structures. Each row of coils in each layer of outer coil structure are aligned in the vertical direction, and coil leads of each row of aligned coils in adjacent layers of outer coil structures are integrally connected and are opposite in winding direction. According to the utility model, interlayer voltage and segment voltage of the coil are reduced, lead length and lead resistance loss are reduced, and the leads do not need to be welded.

The present disclosure relates to the technical field of display, and discloses a display panel and a display device. The display panel comprises a display area and a first area surrounding the bottom of the display area, and comprises a substrate and a multilayer film layer structure. The multilayer film layer structure comprises a first metal layer, a first flat layer, a first electrode layer, a pixel definition layer and a second electrode layer arranged in sequence. A first sub part of the first flat layer is provided with a first channel penetrating in a first direction. A first sub part of the first electrode layer is electrically connected with a part of the first sub part of the first metal layer serving as a negative power voltage trace through the first channel. A first sub part of the pixel definition layer is provided with a second channel penetrating in the first direction. The second electrode layer is opposite in polarity to the first electrode layer, and a first sub part of the second electrode layer is electrically connected with the first sub part of the first electrode layer through the second channel. The display panel can effectively reduce the VSS line impedance without increasing the width of the frame, and solve the problem of high-brightness burn.
