GMC7975CA, also known as side-look type dot matrix display module, is a popular display module featured by its small size and low power consumption. Basically, it is a combination of LED clusters and dot matrix, which enables its multiple functions. This module can be applied to a large selection of fields, such as vehicle telematics, home appliances, small kiosk displays and LED sign boards. It can also be used as alarm indicators, operational panels, numeric display and so on.

GMC7975CA is composed of two parts: matrix and LED clusters. The matrix is responsible for displaying contents, while the LED clusters are mainly used to show symbols. The matrix has 7 rows, each one is composed of 6 LEDs. It can show characters or symbols in the form of a dot matrix. The LED cluster has 4 rows and 3 columns. With 4 colors, such as red, green, yellow and orange, each LED cluster can show independent symbols. In addition, the module supports common English as well as Japanese and Chinese characters.

The working principle of GMC7975CA is quite simple and efficient. It is composed of a microcomputer, a driving logic circuit and a display. When the microcomputer receives signals, it will generate the corresponding controller signal, which will be transmitted to the logic circuit. The logic circuit will then control the display based on the controller signal. The display is composed of a matrix, LED clusters and so on. The control signals from the logic circuit will control the light up and off of the LEDs in the matrix, enabling it to show the selected characters or symbols. The LED clusters can be independently switched on or off via the logic circuit, resulting in the characters or symbols displayed.

GMC7975CA is a great display module featured by its small size, low power consumption and multiple applications. It consists of two parts, the matrix and LED clusters, so it can show characters and symbols as well. Furthermore, its working principle is quite simple and efficient, which ensures a perfect and consistent display effect. Therefore, GMC7975CA is a great choice for a large selection of fields, such as vehicle telematics, home appliances, small kiosk displays and LED sign boards.
