BLC2021-BL Application Field and Working Principle

Backlighting of Liquid Crystal Displays (LCDs) such as standardized character and numeric panels make up a major portion of the global backlight market. The BLC2021-BL series combines two ultra-slim backlight modules with a single board to deliver a simple, cost-effective backlight solution for LCD display applications. This white paper describes the two BLC2021—BL modules, their application field, and the working principle behind them.

Overview of Application Field

The BLC2021-BL is most commonly used in LCD displays in consumer-level devices such as cell phones, laptops and tablets. By providing the best balance of energy efficiency and brightness, these modules have become standard specifications for most LCD displays. In addition to basic LCD applications, these modules are also designed for use in automotive LCD panels, providing the necessary brightness and high-contrast ratios for improved visibility.

Overview of Working Principle

The key component of the BLC2021-BL series is its dual ultra-slim backlight modules which employ a combination of LED light sources and optical lenses to optimize the backlight\'s performance. These modules utilize an LED array and a Reflector Plate (RP) to increase the brightness and uniformity of the backlight. When the LED power is on and current flows into the LED light sources, the LEDs will generate visible light. The generated light then passes through the lens to the display panel. The reflector plate is used to direct the light that is not directly reflected by the lens to other areas of the display panel, forming a more uniform backlight.

Advantages of BLC2021-BL Series

The BLC2021-BL series has many advantages over other backlights for LCD displays. First, it has a low profile, making it perfect for use in space-constrained applications. Second, it is energy efficient, giving it a longer operating life. Finally, it offers a high level of brightness and contrast, making it ideal for applications that require this level of performance.

Conclusion

The BLC2021-BL series provides a simple, cost-effective backlight solution for LCD display applications. With its combination of ultra-slim backlight modules and single board design, this series provides the best balance of energy efficiency and brightness for consumer and automotive LCD displays. Combining LED light sources, optics lenses and reflector plate helps to optimize the performance of each module, and its low-profile design makes it perfect for space-constrained applications.
