LCD photomasks are the master plates used in the manufacture of the LCD
panels found in LCD televisions, computer monitors, and smartphone screens.
They are the essential parts for LCD panel production. In 1985, HOYA
pioneered the development and production of LCD photomasks by applying its
technologies for semiconductor photomasks.
LCD panels have grown significantly in the past ten years, led by growing
demand for LCD televisions, which has been increasing in size every year.
Accordingly, HOYA's LCD photomasks have also grown larger. In addition to
the size, the required level of mask quality has been getting higher. Amid this
trend, HOYA provides panel manufacturers with high-quality, high value-added
products by making use of the technologies it has cultivated through the
development of semiconductor photomasks.
LCD photomasks
In addition to the spread of LCD TVs, recent years have also seen the explosive
growth of smartphones. This has resulted in a significant increase in demand for
medium- and small-size photomasks. Unlike those for LCD TVs, these
photomasks are generally required to be highly precise. This is another area in
which HOYA's technological excellence is utilized.
