Samsung Display will be using Chemtronics as its vendor to handle the back-end etching of OLED panels it plans to supply to Apple for iPads, TheElec has learned.
Chemtronics will be the sole vendor for the process, sources said.
Samsung Display and LG Display are gearing up to start production of OLED panels for iPads that will launch next year.
The pair are planning to use their existing Gen 6 substrate factories to manufacture them.
The panels use glass substrates like rigid OLED panels but also use thin-film encapsulation used in flexible OLED panels, making them the so-called “hybrid OLED” panels.
Cupertino uses plastic substrates and TFE for the OLED panels it uses in iPhones.
Chemtronics will handle the etching of the glass substrate that has finished OLED deposition and encapsulation.
The bottom of the substrate it etched to make them thinner. The glass will be around 0.5mm thick then cut to 0.2mm thick from this process.
The substrate must be uniformly etched, a task that is more difficult for panels for tablets compared to smartphones as they are larger.
Earlier this month, Chemtronics said it plans to spend 24.2 billion won to build a new facility dedicated to Gen 6 OLED etching.
Meanwhile, the latest deal from Samsung Display means Chemtronics will likely also win the etching order for Gen 8 OLED panels later.
As the substrate is even larger, this will be even more difficult.
