GMA21R75 Application Field and Working Principle

The GMA21R75 series by GreenOptECMA Technology (GOET) is a series of multi-channel full-color dot matrix displays aimed at providing a large viewing area with a very small footprint and low power consumption. The GMA21R75 series features high-density display, which makes it an ideal choice for digital signage applications.

This series consists of single-row display modules, that support a wide range of colors up to 24-bits for each pixel. The modules also offer an eye-catching viewing angle of up to 180°. Moreover, these modules are designed for uniform brightness and contrast, which ensures a vivid, true-to-life presentation of the images.

The GMA21R75 displays are based on the latest LED dot matrix technology, which offers high-speed waveform switching capabilities, which ensures a smooth and life-like presentation. This technology also offers excellent image uniformity and reduced unevenness, which makes it an effective solution for various industrial applications.

Apart from being used in digital signage applications, GMA21R75 displays are suitable for a wide range of applications, including outdoor advertising, control systems, automotive displays, video walls, and emergency lights etc.

The working principle behind the GMA21R75 series displays is based on its LED dot matrix architecture. Each LED dot matrix is connected to a single electronic driver, which drives the LED dot matrix at a high-speed waveform frequency. This waveform frequency is independently adjustable for each LED dot matrix, which enables users to customize the brightness and color of the displayed images. Each LED dot can also be individually controlled to form different shapes and sizes of images.

Ultimately, the GMA21R75 series is a powerful and versatile display solution which provides a bright and vivid display resolution at a very small footprint. It is therefore suitable for a wide range of industrial and commercial applications.
