LED-based Backlighted LCD modules, commonly referred to as BLC2021-BL-GW, are widely used for industrial, commercial, and consumer applications where a bright, lighted LCD or LED display is desired. These display modules are used in retail displays, medical equipment, instrumentation, and automotive applications, among others.

The BLC2021-BL-GW display module is a specially designed display module available from several sources. The module is designed with dual-color backlit LCD or LED display and is used for display purposes in a wide range of applications due to its high brightness, slim design, low power consumption, and wide viewing angle. The module is available in various status formats, including characters, digital numbers, various symbols, graphics, animation, and scrolling text.

Working Principle

The BLC2021-BL-GW display module is designed to emit light from two sides of the display, including the LCD side and the rear side of the backlight. The light is emitted only when power is supplied to the unit. The light is then filtered by the LCD panel and beamed to the viewing area. The display uses two different colored LEDs to provide the dual sided backlighting.

The LCD side of the display is the one that interacts directly with the user and displays the images, text, and symbols. It is powered by a dedicated controller board containing the drivers and other circuits necessary for displaying the images, text, and symbols. The rear LED side is connected to its own power supply and is responsible for providing the illumination or backlighting. The backlighting can be fine-tuned by adjusting the power level and color for different applications.

Applications

BLC2021-BL-GW display modules are used in a variety of applications where LCD or LED backlighting is desired. The two sided backlighting helps reduce heat buildup and allows for better visibility of the content on the display, even in challenging environments.

BLC2021-BL-GW display modules are used in a variety of consumer products, including mobile phones, remote controls, and tablets. The slim design and wide viewing angle of the display make it an ideal choice for applications where minimal space and maximum visibility are desired.

The displays are also widely used in automotive applications, industrial instruments, and medical equipment due to their reliable performance and excellent readability in a variety of ambient light conditions.

BLC2021-BL-GW display modules are also widely used in commercial applications, such as retail point-of-sale (POS) systems, kiosks, and digital signage, due to their easy integration and wide feature set.

Conclusion

The BLC2021-BL-GW display module is a versatile, dual-sided LCD or LED backlit display module that is widely used for industrial, commercial, and consumer applications. The module is designed to provide a bright, illuminated display with excellent readability in a wide range of ambient light conditions. The backlight is powered by two different colored LEDs, allowing the user to adjust the backlight level and color to suit different applications. The module is also designed with a slim design and wide viewing angle, making it an excellent choice for applications where minimal space and maximum visibility are desired.
