Samsung Display ‚Hall Design‘ OLED mass production Galaxy S10

Samsung Display announced today that they start the OLED Display mass production with Hall Design for the Galaxy S10 for 2019.
First application to ‚Galaxy S10‘ early next year Unique design will benefit from differentiation
Samsung Display has begun mass production of ‚Hall-shaped organic light emitting diode (OLED)‘ which realizes full screen of smartphone . Hall design full screen will be applied to Samsung Galaxy S10, which will be launched next year.

Samsung Display is producing flexible OLEDs with a Hole In Active Area (HIAA) structure that maximizes the full screen by drilling holes in the panel. This design is produced in the 6th generation line ‚A3‘. This structure was applied to two lines that produce panels for Samsung Electronics in A3. 

Samsung Display ended its project last month with a project to renovate equipment in existing lines with laser related equipment companies such as SFA and Phil Optics to apply HIAA structure.

Samsung Display began mass production of hall design panels as a remodeling equipment without investing additional facilities. Notch Design Smartphones have been in the market for less than a year, so they have reduced their investment costs by replacing their equipment with new ones.

The addition of new equipment to existing lines designed inline also burdensome. There is a possibility that sufficient space is needed in the factory and the existing production flow is disturbed. As a result, it is believed that HIAA structure has been adapted to the existing laser equipment, instead of investing in new equipment.

The hall display, which is named Infiniti-O by Samsung Electronics, should be separately deposited with organic material and thin-film encapsulated according to laser drilling. Because the bezel is thinner, optimizing the spacing between the holes and the bezel does not affect overall performance. Samsung Display is said to have spent a considerable amount of time optimizing the gap between the hall and the bezel.

Samsung Electronics and Samsung Display expect Infiniti-O display to benefit from design differentiation in the market with Samsung’s unique design for the time being. Infinity-O will also highlight the Samsung Galaxy series as a differentiator, as the „edge display“, which is bent on one side of the display, has been a unique design differentiation factor for the Galaxy smartphone for some time.

This is because the HIAA structure technology is more difficult than the notch design. Chinese panel makers with low 6G OLED yields are unlikely to catch up. As Samsung Display applies this structure only to flexible OLEDs rather than rigid OLEDs, it is difficult for China to implement this design in smartphones equipped with rigid OLEDs. The liquid crystal display (LCD) is considered to be more difficult to apply the HIAA structure because of the backlight unit (BLU).

An official familiar with the Samsung HIAA development project said, „If China adopts this design for rigid OLED, the final product can be completed, and if it is implemented as a new investment in flexible OLED, the mass production period will be delayed. The panel will be a good weapon to enhance Samsung’s profitability and secure design differentiation for 2 ~ 3 years. “
