In the test and measurement field, BLC2021-BK-IY can be used to display the parameters of various measuring instruments, such as oscilloscopes, digital multimeters, and so on. In the security field, it can be used to display the status of various security systems, such as the number of visitors in a certain area, the location of security personnel and the security level of the area. In the transportation field, it can be used to display traffic information, such as the speed, position, route and all kinds of road conditions.

Working Principle

BLC2021-BK-IY is a type of LCD (liquid crystal display) module and it works with a simple principle. Basically it has two layers of glass plates with a liquid crystal layer between them. When the drive voltage is applied to the liquid crystal molecules, they align and block the light from the backlight source. Therefore, the different alignment of molecules produce different shades of gray and different colors.

It also has a controller board which will control the supply of drive voltage and the display of data. The controller board contains a memory chip and a timing controller, in which various data and signal such as the display data and timing signals are stored. The controller board also has a signal interface (VCO) which will read the signal from external devices and convert it into a signal that can be used by the display module. To summarize, the controller board will read the data from the external device, store it in the memory and then convert it into a signal which will be sent to the display module to produce the desired image.

Conclusion

BLC2021-BK-IY is a series of LCD display modules with a wide range of application fields and simple working principle. It has two layers of glass plates with a liquid crystal layer in between. When the drive voltage is applied to the module, it will block light from the backlight source and produce different shades of gray and colors to display data. Finally, the controller board will read data from external devices and convert it into a signal that can be used by the display module. These characteristics make BLC2021-BK-IY an ideal solution for applications in industrial automation, instrumentation, test and measurement, medical and healthcare, security, and transportation fields.
