Sources have stated that the reason behind this decision was Samsung's inability to provide the OLED displays according to Apple quality requirements at a workable price, the report said.

The tech giant wants the OLED panels to have two stack tandem structures, with two emission layers, instead of the conventional single-stack structure.

These panels are brighter than the traditional OLED panels and are much more complex and costly to manufacture.

The report has stated that this requirement has made the project financially unviable for Samsung at Apple's price. However, a next-generation manufacturing process would solve the problem by reducing the cost of production, the report said.
