BLC2021-BL-WB Optoelectronics

The BLC2021-BL-WB module is a type of display module used in a wide variety of applications. It is a combination of LCD, OLED character and Numeric display technologies. This combination provides a high resolution graphical and text display with low power consumption. This type of module is suitable for industrial, automotive and consumer applications.

LCD Display Technology

LCD or Liquid Crystal Display is the most common display technology used for devices such as computers, phones, etc. It is used for a variety of applications from digital clocks to monitors. LCDs are cheaper and easier to produce than OLEDs, but their main disadvantage is the need for a backlight which drains the battery of mobile devices.

OLED Character and Numeric Displays

OLED or Organic Light Emitting Diode is a display technology that has been gaining popularity in recent years. Its main advantages compared to LCD are the ability to generate its own light, making it ideal for display in mobile devices, and the fact that they are thinner and more power-efficient. OLED character and numeric displays have the same resolution and brightness as an LCD display and even higher contrast ratio.

Working Principle of BLC2021-BL-WB Module

The BLC2021-BL-WB module consists of three layers: an LCD, an OLED display and an embedded controller. The LCD layer functions as the background/front-end interface of the device, and contains the physical display of the device. The OLED layer, on the other hand, contains the characters, numbers and graphics and is used to display information on the LCD layer. The embedded controller controls the flow of data between the LCD and the OLED layer, allowing for a high level of synchronization between them. The module also contains a wide variety of features such as SPI, UART, I2C interface and several GPIOs, making it ideal for large-scale display applications.

Advantages of BLC2021-BL-WB Module

The BLC2021-BL-WB module offers several advantages over traditional LCD and OLED displays. The first is the fact that it is a combination of LCD and OLED displays, which provides a higher resolution and brighter display than either technology alone. Additionally, the embedded controller allows for easy integration with existing systems and quick customization of the display. The second advantage of this module is its low power consumption, as the combination of LCD and OLED technologies means that less power is used to generate the same image. This makes it ideal for applications such as electric vehicles, where power is at a premium. Finally, the combination of technologies also allows for a wider range of colors and higher contrast ratio, giving it the ability to display more detailed images.

Conclusion

The BLC2021-BL-WB module is a great choice for those who need high resolution and low power consumption displays. Its combination of LCD and OLED technologies allow for a brighter, more efficient display, while the embedded controller makes it easy to integrate into existing systems. Its low power consumption makes it ideal for power-hungry applications, while its wider range of colors and higher contrast ratio give it the ability to display more detailed images.
