Samsung Display and its competitor LG Display are about to launch the production of a new display technology – micro-Oled. These new high-resolution miniature screens are made for AR and VR.
Aiming for pixel density (expressed in pixels per inch) by taking advantage of very high definitions on particularly small diagonals, this is one of the reasons for micro-Oled display technology, an alternative to micro-LEDs that Samsung and LG are at point of launch in their respective production lines. The two Korean giants would bet first on a small-scale production of micro-Oled screens, with limited volumes manufactured from the second half of 2023 according to information fromETNews.
According the electLG Display would have already positioned itself with Meta and SK Hynix to develop and produce, this time on a large scale, micro-Oled panels by 2025 or 2026. For its part, Samsung Display would target its micro-Oled screens at Samsung Electronics (for internal use , therefore), but also Qualcomm and Google.
micro-Oled: a core technology for AR/VR
Note that it’s also not impossible for Apple to look to supply LG or Samsung with micro-Oled displays for their future AR/VR devices, but for its first headset, the brand would first turn to Sony’s micro-Oled production, note FlatPanelsHD.
In any case, the micro-Oled is central to the projects of the different manufacturers of AR/VR helmets and glasses. Developed especially for this use from the beginning, this technology could also be used later in other products such as cameras (for the viewfinder of SLR or hybrid cameras, for example) or binoculars.
The world of semiconductors put to work
As far as micro-Oled tile manufacturing goes, it’s a bit special. The process consists of depositing organic LEDs (Oled) on a thin sheet of silicon, and not on glass or plastic substrates. Therefore, this method requires knowledge related to semiconductor manufacturing… which theoretically benefits Samsung.
In fact, the company can count on the Samsung Foundry facilities to create its micro-Oled screens completely in-house, while LG must, for its part, partner with a third party: SK Hynix. The latter would have offered to use its 28 nm or 45 nm lines, already available in South Korea. Engraving fineness sufficient in both cases for the intended use.
