Organic light emitting diode display device, method of manufacturing the oled display device, and electronic device

A method of manufacturing the organic light emitting diode (OLED) display device, wherein the manufacturing method comprises the following steps:

• providing a substrate having a hollow region, a display region located at an outside of the hollow region, and a non-display region located between the hollow region and the display region;
• forming at least one isolation portion disposed on the substrate of the non-display region, wherein the at least one isolation portion is used for a first light emitting device layer and from a second light emitting device layer;
• forming a light emitting device layer on the substrate, the light emitting device layer which comprises the first light emitting device layer and the second light emitting device layer, the first light emitting device layer formed on a side of the isolation portion of the substrate close to the display region, the second light emitting device layer formed on a side of the isolation portion of the substrate close to the hollow region;
• forming an encapsulation layer covering the light emitting device layer, the isolation portion, and the substrate;
• and
• forming a through-hole located in the hollow region and extending through the substrate, the second light emitting device layer, and the encapsulation layer.
