Introduction

The BLC2021-BK-USB-R is a versatile and affordable display module for LCD, OLED character and numeric display applications. It is equipped with a wide range of features that allow it to be used for a variety of applications, from embedded system control to complex data logging.

Technical Specifications

The BLC2021-BK-USB-R comes in two versions: a 5.7" display and a 7.0" display. Both are powered by a microcontroller, which can be configured to run with a wide range of programming languages, such as C and assembly, which allows for higher level of customization. It comes with an RS-232 serial port, a USB port and a 5V power supply.The 5.7" display offers a resolution of 320x240 pixels, while the 7.0" display can reach up to 800x480. The display itself is comprised of two-channel LED backlighting, as well as a contrast adjustment knob.

Application Field

The BLC2021-BK-USB-R is ideal for embedded system control, data logging, data acquisition and factory automation. It is also suitable for a wide range of applications that require an LCD display, from real-time industrial applications to complex data processing.It is also perfect for applications that require detailed graphic display and performance, such as customer service kiosks, POS systems, and industrial control panels. Additionally, it can be used for point-of-sale machines, telecommunication equipment and medical equipment.

Working Principle

The BLC2021-BK-USB-R utilizes a microcontroller to control the LCD and OLED display. The data is first stored in the microcontroller’s memory, and then sent to the LCD/OLED display via the serial port.The LCD/OLED display is connected to the microcontroller via the serial communication protocol (UART, I2C, SPI, etc.), and the microcontroller can communicate with the display through this protocol. The microcontroller can detect the type of display (LCD or OLED) and send the relevant data accordingly.Once the data is successfully sent, the LCD/OLED display will display the data according to the instructions from the microcontroller. This process allows the display to dynamically change the data on the display as it receives new information from the microcontroller.

Conclusion

The BLC2021-BK-USB-R is a versatile display module which is ideal for LCD, OLED character and numeric displays. It is powered by a microcontroller that can be programmed to run with a variety of programming languages. The module is suitable for embedded system control, data logging, data acquisition and factory automation, as well as a range of applications requiring a detailed graphical display. It utilizes a serial communication protocol to control the LCD/OLED display and can thus dynamically change the data the display should show.
