All standard Winstar OLED displays have built-in 4 sets of fonts: English, European, Japanese and Cyrillic. Thanks to usage of many languages, this solution extends the range of applications on various markets. Selected characters from the extended set of fonts can also be used by application developers as icons. Additionally, embedded fonts significantly speed up applications development in graphic displays. There is no need to design and program own fonts as user can just choose and apply a suitable one.
