Taking the BLK204-7T-1U-BK-YG display module as an example, this article will provide an overview of its application field and its working principle.

Application field

BLK204-7T-1U-BK-YG is an LCD character and numeric display module produced by Futaba, a Japanese electronics manufacturer. It is composed of a 7-segment LED display unit, seven LED\'s and two switches. Generally speaking, due to its ability to display characters and numbers, it is widely used in various applications, including scores and time display, temperature display, instrumentation displays, calculators, etc. In addition, due to its high reliability, energy-saving capability, and wide operating temperature range, it is also suitable for many industrial installations.

Working principle

BLK204-7T-1U-BK-YG operates by using “7-segment display” technology. The display module is divided into 7 segments, each of which can be turned on individually. By controlling the current applied to each segment, it is possible to display any character or number. When a segment is ON, the current will flow through the segment to the LED and turn the LED ON, thereby displaying a specific character or number.

When displaying a character or number, BLK204-7T-1U-BK-YG also uses two switches, one for the common and one for the segment. By activating these switches, the appropriate current can be supplied to the necessary segment, and thus the corresponding character or number can be displayed. In addition, through the two terminals of the power supply, DC power can be supplied and the display can be turned ON or OFF.

Conclusion

BLK204-7T-1U-BK-YG is an LCD character and numeric display module produced by Futaba. Its application fields include scores and time display, temperature display, instrumentation displays, calculators, etc. It operates by using “7-segment display” technology, which is composed of seven segments, each of which can be individually turned on. Two switches are also used, one for the common and one for the segment, in order to activate the segment and display the corresponding character or number.
