Display panel and method for manufacturing same, and display device

A method for manufacturing a display panel, comprising:

• providing a base substrate, wherein the base substrate comprises a display region and a periphery region at least partially surrounding the display region, wherein the display region comprises a first display region and a second display region disposed at least on one side of the first display region, a light transmittance of the first display region being greater than a light transmittance of the second display region;
• and
• forming a plurality of first pixel units and a plurality of signal lines on the base substrate, wherein the plurality of first pixel units are disposed in the first display region, the plurality of signal lines are disposed at least in the first display region and electrically connected to the plurality of first pixel units, and the plurality of signal lines comprise a plurality of first signal lines and a plurality of second signal lines, wherein a first portion of each of the plurality of first signal lines is a metal signal line and is disposed at least in the first display region, and a first portion of each of the plurality of second signal lines is a metal oxide signal line and is disposed at least in the first display region;
• wherein in a case that a ratio of a first size of the first display region to a second size of the first display region is greater than 2, the plurality of first signal lines comprise at least one of gate signal lines;
• and in a case that the ratio of the first size of the first display region to the second size of the first display region is less than 0.5, the plurality of first signal lines comprise at least one of data signal lines;
• wherein the first size of the first display region is a size of the first display region in an extension direction of the gate signal lines, and the second size of the first display region is a size in an extension direction of the data signal lines.

A display device, comprising:

• a power supply assembly and a display panel, wherein
• the display panel comprises:
• a base substrate, comprising a display region and a periphery region at least partially surrounding the display region, wherein the display region comprises a first display region and a second display region disposed at least on one side of the first display region, a light transmittance of the first display region being greater than a light transmittance of the second display region;
• a plurality of first pixel units disposed on the base substrate and in the first display region;
• and
• a plurality of signal lines disposed at least in the first display region and electrically connected to the plurality of first pixel units, wherein the plurality of signal lines comprise a plurality of first signal lines and a plurality of second signal lines, wherein a first portion of each of the plurality of first signal lines is a metal signal line and is disposed at least in the first display region, and a first portion of each of the plurality of second signal lines is a metal oxide signal line and is disposed at least in the first display region;
• wherein in a case that a ratio of a first size of the first display region to a second size of the first display region is greater than 2, the plurality of first signal lines comprise at least one of gate signal lines;
• and in a case that the ratio of the first size of the first display region to the second size of the first display region is less than 0.5, the plurality of first signal lines comprise at least one of data signal lines;
• wherein the first size of the first display region is a size of the first display region in an extension direction of the gate signal lines, and the second size of the first display region is a size in an extension direction of the data signal lines;
• and the power supply assembly is configured to supply power to the display panel.
