The WEH002002A is a state-of-the-art COB (Chip-on-Board) structured OLED (Organic Light-Emitting Diode) display module, designed to deliver exceptional performance and versatility in a compact form factor. This module features a 20x2 character configuration, making it ideal for applications that require clear and concise alphanumeric information display. With a diagonal module size of 3.08 inches and an active display area of 77.30 x 11.85 mm, the WEH002002A offers a balance between size and readability, ensuring that it can be easily integrated into a wide range of devices and systems.
At the heart of the WEH002002A is the WS0010-TX all-in-one font IC, which provides comprehensive support for a variety of character sets, including ASCII, English, Russian, European, and Japanese. This built-in ROM standard font library ensures that the module can be used in diverse linguistic environments without the need for additional hardware or software modifications. The module supports multiple interface options, including the default 6800 interface, with optional 8080 or SPI interfaces, offering flexibility in terms of connectivity and integration with different microcontrollers and systems. The 1/16 duty drive mode further enhances the module's efficiency, ensuring smooth and reliable operation.
One of the standout features of the WEH002002A is its compatibility with the Winstar LCD WH2002A in terms of outline dimensions (116.0 x 37.0 mm) and view area size (85.0 x 18.6 mm). This compatibility extends to the pinout configuration, making the WEH002002A an excellent drop-in replacement for existing STN (Super Twisted Nematic) character displays. This feature is particularly beneficial for manufacturers looking to upgrade their products without the need for extensive redesigns or retooling.
The WEH002002A OLED module is designed with performance and durability in mind. It boasts a faster response time of just 10 microseconds at +25°C, ensuring that information is displayed quickly and accurately. The module's unlimited viewing angle of up to 175 degrees provides excellent visibility from virtually any angle, making it suitable for applications where the display may be viewed from different perspectives. The self-emitting technology of the OLED eliminates the need for a backlight, resulting in a thinner design and lower power consumption. This technology also contributes to the module's high brightness and impressive contrast ratio of up to 10,000:1, ensuring that the display remains clear and legible even in challenging lighting conditions.
The WEH002002A is engineered to operate reliably across a wide temperature range, from -40°C to 80°C, making it suitable for use in both industrial and consumer applications. Its low power consumption not only enhances energy efficiency but also contributes to reduced CO2 emissions, aligning with global sustainability goals. The module's integrated PCB board simplifies the design and manufacturing process, as customers do not need to develop additional PCBs. Furthermore, the inclusion of four screw holes on the PCB board facilitates easy and secure installation, reducing assembly time and costs.
Operating at a logic supply voltage ranging from 4.8V to 5.3V (typically 5.0V), the WEH002002A ensures stable and consistent performance. The module's storage capabilities extend from -40°C to +85°C, providing additional assurance of its durability and reliability in various environmental conditions. Additionally, the WEH002002A offers multiple emitting colors, allowing customers to choose the option that best suits their specific application requirements.
In summary, the WEH002002A OLED display module is a highly versatile and efficient solution for applications requiring a 20x2 character OLED display. Its combination of advanced features, including fast response time, wide viewing angle, high brightness, and low power consumption, makes it an excellent choice for upgrading existing STN character displays or integrating into new designs. The module's compatibility with the Winstar LCD WH2002A, along with its integrated PCB board and easy installation features, further enhances its appeal to manufacturers and designers. Whether for industrial, commercial, or consumer applications, the WEH002002A delivers reliable performance and exceptional functionality, making it a standout choice in the realm of character OLED displays.
