Introduction

OK162-12-OB is a monochrome LCD display module with a character size of 12.7 mm x 8.3 mm. It is built with FSTN technology, which is a merge of both transflective and transfinitive optics to create a higher contrast display with excellent wide viewing angle. Moreover, this module also adopts a chip on board (COB) encapsulation technique, making it an ideal choice for mobile products, medical and industrial applications.

Application Field and Working Principle

OK162-12-OB display module is mainly used for character and numeric display and segment displays in applications such as mobile products, medical, and industrial applications. Its FSTN technology is beneficial to enhance the visibility from different angles, which is perfect for outdoor usage. Moreover, it is environmentally friendly and has a long product lifetime, making it a reliable choice for customers. The principle of operation lies in the use of a liquid crystal display (LCD). In this display, two glass plates coated with indium-tin-oxide are arranged in parallel and contain liquid crystals between them. An electrical current is used to control the passage of light through the liquid crystals. This can be done by a voltage difference, which is generated across the two plates. When a voltage difference is applied across the liquid crystals, they switch from a non-polarized state to a polarized state, thus allowing light to be passed through. By controlling this feature, we can control what is displayed on the display.

Contrast & Backlight

The contrast of the OK162-12-OB display module is up to 200:1, thanks to the FSTN technology. The display acts in a reflective mode, with an internal backlight available for higher brightness and wider viewing angles. The backlight consists of a white LED, which provides an average brightness of 700 to 900 cd/m2 depending on the viewing angle. To conserves power, the LED backlight has a power-up duration of 30ms, making it well-suited for mobile products, medical and industrial applications.

Characteristics

OK162-12-OB display module has certain characteristics that are beneficial for its applications. It has a 5V power supply range from LCD, driving voltage 4.2V, rising/falling time 4V/µs, response time up to 60ms. In addition, the temperature operating ranges are -20℃～+70℃. The module has a size of 128.64mm x 64.84mm and a module thickness of 6.8mm, making it suitable for compact designs.

Conclusion

OK162-12-OB is a versatile display module with an array of features, making it an ideal choice for character and numeric display, segment displays, and wide viewing angle applications. The FSTN technology and COB encapsulation technique are beneficial to enhance the contrast and reduce the thickness, making it suitable for usage in outdoor and mobile products, medical and industrial applications. The 5V power supply range, driving voltage and rising/falling time characteristics make it a reliable display for these applications.
