Korea’s Segyung Hightech was the sole supplier of the special protective film for the cover windows of Samsung’s Galaxy Z Flip unveiled on Feb. 12, according to industry watchers. This marks the second time for the firm to supply Samsung after providing transparent PI film for the Galaxy Fold launched in 2019.
Segyung Hightech’s special protective film is applied on top of the cover window to protect the smartphone display and also improve the touch sensors.
The Galaxy Z Flip’s cover window uses a 30㎛ Ultra Thin Glass (UTG) that is less flexible than the transparent PI film used for the cover window of the Galaxy Fold, but it boasts improved optic function and is less prone to damage. But UTG is still breakable, and consequently requires a protective film.
Due to Segyung’s widening expertise, Samsung is likely to continue relying on it for protective film for the second generation Galaxy Fold that is due out in the second half of this year. As Samsung is aiming to push out a wide portfolio of foldable phones to build the customer base, market watchers expect Segyung Hightech’s revenues to rise in tandem.
Samsung Electronics is said to be targeting sales of up to 5 million foldable handsets this year. This is about 10 times that of the Galaxy Fold, which sold around 500,000.
In May 2019, Segyung Hightech purchased a plant in Suwon for KRW 3 billion to produce the protective film. Its second plant completed in Vietnam last year also has the film producing capacity.
The company was listed on the Kosdaq market in July 2019. Its sales that year rose 10.5% to KRW 283.6 billion, according to market estimates. A 11.7% decline is forecast for its operating profit. About half of its sales comes from producing decorative film for smartphones.
Smartphone filmmakers may see a further boom in business in the future, as some manufacturers are choosing to go with double-layer cover windows. The Mate X unveiled by Huawei Technologies in 2019 is one such model that uses applied both a transparent PI film and a protective film – mainly to step up protection for the outward-folding display. Motorola’s RAZR folds inwards, but it also used uses to layers for the cover window. Samsung’s Galaxy Fold and the Galaxy Z Flip, however, uses one layer.
