1. An organic light-emitting display (OLED) panel, comprising:
a light-emitting substrate,
a wall-shaped elastic conductor including a metal cap on its top, and
a color filter substrate; wherein
the light-emitting substrate comprises:
a first substrate,
a first electrode layer including a matrix of first electrodes,
a pixel definition layer,
a light-emitting layer, and
a second electrode layer, wherein
the pixel definition layer comprises a plurality of opening structures exposing a portion of the first electrodes,
the light-emitting layer is on one side of the first electrode layer facing away from the first substrate, and
the second electrode layer is on one side of the light-emitting layer facing away from the first substrate;
the color filter substrate comprises:
a second substrate,
a color filter layer formed by a plurality of sub-pixel color filters, and
a conductive layer; wherein
a continuous groove structure in a grid shape is configured on the pixel definition layer between adjacent sub-pixels,
the second electrode is partitioned into a plurality of metal pieces by the groove structure,
the wall-shaped elastic conductor completely covers the groove structure in a direction perpendicular to the first substrate, and
the plurality of metal pieces of the second electrode are electrically reconnected by the metal cap disposed on the wall-shaped elastic conductor,
the wall-shaped elastic conductor is sandwiched by the light-emitting substrate and the color filter substrate in a manner that a vertical projection of the wall-shaped elastic conductor on the light-emitting substrate completely covers a vertical projection of the pixel definition layer on the light-emitting substrate, and the metal cap is in contact with either the second electrode layer in the light-emitting substrate or the conductive layer in the color filter substrate.
