Introduction to OK204-25-OY

The OK204-25-OY is a low cost alternative to traditional LCD and OLED display modules. It is a 4 line X 20 character oled display that operates in the same way as other OLED displays. It has 5x7 font size and a contrast ratio of 160. It is a CMOS based device and thus does not require a backlight to provide visibility. This allows low current consumption and a smaller size.

Application field

The OK204-25-OY is highly suitable for applications where display modules need to be designed into limited spaces. It is used commonly in medical instrumentation, home appliances and vending machines. The most preferable features are the low power consumption and space saving. Since it does not require a backlight, the device has a long lasting life-time. The OK204-25-OY is also suitable for surface mounted applications due to its low profile and light weight. The device also offers wide viewing angles making it perfectly suitable for instrument panels and kiosks.

Working principle

Other than low power consumption and wide viewing angle, the OK204-25-OY display offers a range of features. The display supports 5x7 font size and can display up to 4 lines and 20 characters. It is built with a controller for driving the display. It works by direct connection to the system and provides an interface to various digital signals. The incoming data is then converted into an internal code and sent to the display based on signals. When the display is configured as 8-bit parallel, an external controller is needed as an interface between the system and the display.

Depending on the source, the OK204-25-OY display can be driven both by 5V and 3.3V Vcc, while the logic level is TTL compatible. A DC/DC converter can also be used to provide power to the display. It supports read/write and write only mode. This allows easier programming and updating by hardware engineers.

The character size is in-turn decided by the font library and can be configured along many lines. It includes an onboard storage for fonts, patterns, and framing formats which can be used for programs and graphics. In terms of speed, the display can display up to 40.5 characters per second in 8 bit parallel mode.

Conclusion

In short, the OK204-25-OY is a low cost, efficient OLED display module. Its features, wide viewing angles and long-lasting life-time makes it ideally suitable for projects where space is at a premium. With its low power consumption and wide range of features, this display is becoming increasingly popular with hardware engineers.
