OLED substrate and OLED display apparatus

An organic light-emitting diode (OLED) substrate comprising:

• a base substrate, comprising a display region, the display region being divided into a plurality of luminous regions and a non-luminous region separating one or more adjacent luminous regions, the non-luminous region comprising a plurality of first connection regions;
• a first electrode layer provided over the base substrate, wherein the first electrode layer comprises a plurality of first electrodes, the projection of the plurality of the first electrodes on the base substrate covers the plurality of luminous regions;
• a pixel defining layer provided on the first electrode layer, wherein the pixel defining layer is located at the non-luminous region and defines the plurality of luminous regions, the pixel defining layer is hollowed out at the first connection regions;
• an electroluminescent functional layer provided on the pixel defining layer;
• a second electrode layer provided on the electroluminescent functional layer;
• and
• a plurality of conductive structures located at the plurality of first connection regions respectively, wherein the plurality of conductive structures are electrically coupled to the second electrode layer;
• wherein
• the electroluminescent functional layer is disconnected from the first connection regions at an edge portion of the first connection regions;
• surfaces of the conductive structures that are opposite from the base substrate are higher than a surface of the pixel defining layer that is opposite from the base substrate both with respect to an upper surface the base substrate;
• the conductive structures are located at a side of the second electrode layer that is opposite from the electroluminescent functional layer;
• and
• the non-luminous region further comprises a plurality of second connection regions, wherein at least one second connection region is adjacent to at least one first connection region;
• wherein the OLED substrate further comprises:
• a plurality of elevating cushions provided at the second connection regions;
