LDM-2124757NI

LDM-2124757NI is a high-performance display module with LED dot matrix and cluster. It adopts SMD LED chips, which has the advantages of high brightness, long life and low power consumption. And it is widely used in industrial, medical and communication fields, such as high speed camera, CCTV, 3C equipment and so on.

The working principle of the LDM-2124757NI is self-luminous. The dot matrix is composed of dot pairs and matrix, and the matrix is composed of two dot pairs from different angles, which are staggered and formed. The two dot pairs are connected in parallel and supplied with current. When a certain voltage is applied forward, the electrons in the PN junction will emit light, and each group of red and green dots will emit red and green light respectively. Different colors can be composed by adjusting the voltage and the ratio of red and green dots.

In addition, the working mode of LDM-2124757NI is digital scan. The controller sends a signal to the dot matrix, and each LED lights up. The circuit is composed of LED dot matrix, LED driver board and LED control board. LED dot matrix faces outward and consists of LED dot pairs, which can be connected in series or in parallel; LED driver board is used to drive LED dot matrix to work; LED controller board is composed of control circuit and memory circuit, which can extract the content that needs to be displayed and output the driving signal. By controlling the driving signal sent to each dot matrix, it can control the brightness of each LED, so as to display various patterns and characters.

In summary, LDM-2124757NI is a high-performance display module with LED dot matrix and cluster. It is widely used in various fields such as industrial, medical and communication, and its working principle is self-luminous and digital scan. The display pattern is composed of dot pairs and matrix, and the voltage and ratio of red and green can be adjusted to form different colors. The circuit is composed of LED dot matrix, LED driver board and LED control board. Owing to the basic principle of self-luminous and the advantage of long life and low power consumption, LDM-2124757NI has been widely applied in various fields.
