Samsung Display is reportedly planning to use inkjet printing technology in the upcoming foldable smartphone for bezel development. Using the inkjet printing method in bezel development may save manufacturing costs compared to bezels made using the existing MDD thermal transfer method.

The South Korean tech giant is also considering a reduction in the manufacturing cost of foldable phones. Samsung Display is expected to launch the new foldable smartphone in the second half of this year using inkjet printing.
The bezel on the edge of the smartphone’s organic light emitting diode (OLED) screen is used to cover the internal wiring or metal electrodes of the OLED. The part of the display where information is displayed is called the image display area, and the remaining part is called the non-display area.
In the foldable phone OLED panel process, a thin film encapsulation (TFE) process is performed to protect the OLED from moisture and oxygen, then a bezel film is attached, and then ultrathin glass (UTG), which is the foldable phone panel cover window, is bonded (laminated).
Sekyung Hi-Tech’s MDD (Micro Dry process Decoration) heat transfer process was used to create bezels for Samsung Electronics’ Galaxy Z5 series of foldable phones and regular bar-type smartphones that were released until last year. In this method, a bezel film is made through the MDD heat transfer process, and this film is cut as needed and used as a bezel.
Apart from the above news, Samsung is also working on an “entry-level” variant of its upcoming foldable phone, the Galaxy Z Fold 6.
As per the report, an “entry-level” Galaxy Z Fold 6 will help Samsung to “increase the penetration rate of the foldable phone market,” especially as more foldables come out of China.
