Display panel, method for manufacturing the same, and display device

A method for manufacturing a display panel, comprising:

• forming a packaging layer at a side of a substrate, wherein:
• the packaging layer comprises an organic packaging layer,
• the organic packaging layer comprises a first packaging portion and a second packaging portion which are different in thickness due to a coffee-ring effect, and
• a display region of the display panel comprises a first region, in which the first packaging portion is disposed, and a second region, in which the second packaging portion is disposed, and the second region is closer to a boundary of the display region than the first region;
• and
• forming a touch control electrode at a side of the packaging layer away from the substrate, wherein:
• the touch-control electrode is a mesh electrode comprising a plurality of first metal lines,
• the plurality of first metal lines in the first region is fabricated from a pattern having a first preset width for each first metal line,
• the plurality of first metal lines in the second region is fabricated from another pattern having a second preset width for each first metal line, and
• the second preset width is equal to the first preset width plus a compensation width, wherein the compensation width is determined based on a degree of the coffee-ring effect.

A display device, comprising a display panel, wherein the display panel comprises:

• a substrate;
• a packaging layer disposed at a side of the substrate, wherein:
• the packaging layer comprises an organic packaging layer,
• the organic packaging layer comprises a first packaging portion and a second packaging portion which are different in thickness, and
• the display region comprises a first region, in which the first packaging portion is disposed, and a second region, in which the second packaging portion is disposed;
• and
• a touch-control electrode, disposed at a side of the packaging layer away from the substrate, wherein:
• the touch-control electrode is a mesh electrode comprising a plurality of first metal lines,
• an average width of the plurality of first metal lines in the first region is equal to a first width, an average width of the plurality of first metal lines in the second region is equal to a compensated width, and the plurality of first metal lines is subject to width compensation in the second region;
• an absolute difference between the first width and the compensated width ranges from 0 to 0.32 μm;
• and
• at least one of:
• a first opening region of the display panel is surrounded by the display region, an inner boundary of the display region is adjacent to the first opening region, the second region comprises a first sub-region adjacent to the inner boundary, and the first sub-region comprises a first compensation region surrounding the first opening region and a second compensation region surrounding the first compensation region;
• the second region comprises a second sub-region adjacent to an outer boundary of the display region, the second sub-region comprises a third compensation region and a fourth compensation region surrounding the first region, and the third compensation region surrounds the fourth compensation region;
• or
• a second opening region of the display panel is surrounded by the display region, an inner boundary of the display region is adjacent to the second opening region, an outer boundary of the display region comprises a first edge, the second region comprises a third sub-region adjacent to the first edge, and the third sub-region comprises:
• a fifth compensation region located between the inner boundary and the first edge,
• two sixth compensation regions located at two sides, respectively, of the fifth compensation region along a first direction parallel with the first edge, and
• a seventh compensation region located at a side, of the fifth compensation region and the two sixth compensation regions, away from the first edge.
