A dual-color LED display is a display made of LED (Light Emitting Diode) technology.
Its main feature is that each pixel is composed of LED tubes or crystals of two primary colors (usually red and green).
The following is a detailed introduction to the dual-color LED display:
Definition and composition
Definition: A dual-color LED display refers to a display that can emit red and green light at each pixel, and display more colors (such as yellow when red and green emit light at the same time) through the combination of these two colors.
Composition: The dual-color LED display consists of LED pixel modules, dedicated display driver circuits, DC regulated power supplies, software, frames, and exterior decorations. These components work together to form a complete LED display.
Display effects and features
Color combination: The dual-color LED display can emit red, yellow, and green through the combination of red and green primary colors.
This color combination makes the display have a certain richness in color performance.
Grayscale: Each primary color usually has 16X16 grayscale in a dual-color LED display, which means that each color can have 256 different brightness levels.
Further, some advanced dual-color LED displays may support 256X256 grayscale, that is, 64K different brightness combinations, which greatly improves the delicacy and layering of the display effect.
Widely used: The dual-color LED display has bright and eye-catching colors, vivid visual effects, and better information display utility.
Therefore, it is widely used in subways, airports, commercial centers, wedding shops, restaurants and other places for information release and communication.
Comparison with other types of displays
Compared with monochrome LED displays: dual-color LED displays are richer in color performance and can display more color combinations.
Compared with full-color LED displays: Although full-color LED displays can display richer colors and more delicate picture effects, dual-color LED displays have more advantages in cost, and in some application scenarios (such as text, data, and simple graphics display) are sufficient to meet the needs.
Notes
* When choosing a dual-color LED display, it is necessary to determine the appropriate pixel density, brightness, viewing angle and other parameters according to the specific application scenario and needs.
* During use, it is necessary to pay attention to the maintenance and care of the display to extend its service life and maintain a good display effect.
In summary, the dual-color LED display is a cost-effective display type, which has significant advantages in color performance, cost-effectiveness and wide application.
