First OLED iMac, QD method adopted...LGD considering exhibition of 'Flip' at IMID next week
Apple is reportedly considering launching its first organic light-emitting diode (OLED) iMac display technology between 2029 and 2030, and it has been determined that Samsung Display's large quantum dot (QD)-OLED will be used. LG Display also aimed to supply the first OLED iMac with its large white (W)-OLED technology, but it did not receive approval from Apple.

An industry source A said on the 12th, "(The first) Apple iMac OLED has been decided to use Samsung Display's QD-OLED technology" and "LG Display is not responding for now." Another source B also said, "The technology for the first OLED iMac has been decided as QD-OLED," and "LG Display will aim to respond with the next model."
The reason why only Samsung Display is responding to Apple's first OLED iMac is presumed to be due to mass production capability and luminance, among other factors.
Samsung Display proposed a 5-stack (B-B-G-B-G) product, which has been in mass production since last year, as an OLED for the iMac to Apple. The 5-stack adds a green (G) layer, giving it an advantage in luminance. Samsung Display is expected to send a 220PPI (Pixels Per Inch) level OLED sample from its QD-OLED line to Apple in the latter half of this year.
Samsung Display has been mass-producing 160PPI QD-OLED for monitors, but 220PPI is higher. In March, Semes announced that it had shipped a QD-OLED inkjet printer capable of supporting 220PPI. Samsung Display will send a 220PPI iMac OLED sample to Apple using this equipment and then continue mass production of 160PPI QD-OLED as before.
For monitors like the iMac, which have a shorter viewing distance than TVs, higher pixel density (PPI) and luminance are required for text readability and image quality precision.

Meanwhile, LG Display also has a long-term plan to respond to Apple IT OLEDs, including iMacs, with 'Flip' technology. Flip technology, which patterns RGB OLED subpixels using an exposure process instead of FMM, is commonly referred to as 'eLeap'(eLEAP·JDI technology name) in the industry. Mass production has not yet been verified.

Since Apple's first OLED iMac is expected to be launched between 2029 and 2030, the situation may change. Industry source C said, "There is still a lot of time left until the launch of the iMac OLED, so there could be changes (such as LG Display rejoining the development)."
Before Apple first launched an OLED iPad with a dual tandem (two layers of RGB OLED emissive layer) method in 2024, it had halted the development project for a single stack (one layer of RGB OLED emissive layer) OLED iPad. Product lineup and volume are cited as reasons.
