Introduction

BLC2021-BL-FB is a cutting edge display module created by Chen Hua Display Co., Ltd. This module is intended to offer users an economical solution for a wide range of applications that require low power, efficient display performance. The module will offer a combination of both character and numeric display with a pixel resolution of 255x169. It is capable of providing an extended lifespan of 10,000 hours of uninterrupted usage. With the above features, this display module can be used in various applications such as automotive display, industrial or commercial control systems and many more. In this article, we will explore the application field and working principle of the BLC2021-BL-FB display module.

Application Field of BLC2021-BL-FB

BLC2021-BL-FB offers users a range of applications due to its 81x81 pixel resolution and low power consumption. It can be used in automotive and industrial applications for on-screen controls, instrument clusters, data displays and other applications involving LCD and OLED Character and Numeric displays. It is also suitable for commercial and residential applications such as digital signage and advertising. It can also be used in medical sprays and bulk storage devices as part of the medical industry.

Working Principle of BLC2021-BL-FB

The working principle of the BLC2021-BL-FB display module is based on the use of liquid crystal displays (LCDs) and organic light-emitting diodes (OLEDs). These displays work by changing the polarization of light through the use of electric fields. The LCD display consists of a liquid crystal material sandwiched between two electrodes. The OLED, meanwhile, consists of an organic material that generates light when an electric current is applied.When a voltage is applied across the two electrodes, the liquid crystal material in the LCD changes its orientation, which changes the polarization of the light. This change in polarization results in the display displaying different images or characters. For the OLED, this is done by exciting the organic material with an electric current, which in turn generates light. The intensity and color of the light depend on the type of organic material and the amount of current applied.Now let’s look at how the BLC2021-BL-FB module works. The module uses an FSTN (Film-compensated Super Twisted Nematic) display. This type of display has a higher brightness than conventional LCDs and uses less power, allowing for longer life and lower costs. In addition, the display has an external controller that allows the user to interact with it. The controller can also be used to change the color and brightness of the display. The BLC2021-BL-FB module also has a backlight LED for added brightness and better visibility of the characters and numbers. The LED intensity can be adjusted by the controller, allowing for brighter and clearer images. The display module also has a temperature sensor that will return the temperature of the module when it is activated. This will help ensure the display performs optimally in different temperatures.

Conclusion

In conclusion, the BLC2021-BL-FB display module is an excellent choice for applications that require low power, efficient display performance. It is suitable for automotive, industrial, and commercial applications, as well as medical sprays and bulk storage devices. The display uses an FSTN display, an LED backlight, and a controller to allow users to interact with the display and adjust its brightness and temperature. The BLC2021-BL-FB is one of the most reliable and cost-effective displays on the market today, making it the go-to solution for a wide range of applications.
