There are significant differences between full-color LED display and dual-color LED display in many aspects, mainly including composition color, display effect, application field and technical characteristics.
The following is a detailed introduction to the difference between the two:
1. Composition color
Full-color LED display: It uses three primary color light-emitting tubes of red, green and blue (RGB).
Each color has 256 grayscale levels and can combine 16,777,216 colors.
This rich color combination enables the full-color LED display to present very realistic images and video effects.
Dual-color LED display: It usually contains only two primary color light-emitting tubes of red and green.
Each color also has 256 grayscale levels. When the red and green light-emitting diodes emit light at the same time, yellow light can be generated.
Therefore, the dual-color LED display can mainly display the three colors of red, yellow and green and their different grayscale combinations.
2. Display effect
Full-color LED display: Because it uses three primary colors of RGB, it can restore almost all the colors of visible light, so the display effect is very realistic, rich in color and natural transition. When displaying complex images and videos, it can present a delicate and clear picture.
Dual-color LED display: Although it can display multiple colors, it is limited by the number of primary colors, and its color richness and transition effect are relatively weak. When displaying complex images and videos, color distortion or unnatural transition may occur.
3. Application field
Full-color LED display: Due to its excellent display effect and rich color expression ability, it is widely used in various occasions that require high-quality visual display, such as outdoor advertising, stadiums, large commercial plazas, concerts, cinemas, etc.
Dual-color LED display: Although it can also meet basic visual display needs in some occasions, due to its relatively weak color expression ability, it is more used in some occasions where color requirements are not particularly high, such as simple information release, traffic instructions, etc.
4. Technical characteristics
Full-color LED display: It adopts advanced LED technology and control technology to achieve high brightness, high clarity, high reliability and low power consumption display effects.
At the same time, its electronic components are relatively small, the failure rate is low, and the maintenance cost is relatively low.
Dual-color LED display: It is relatively simple in technical characteristics, and mainly relies on the combination of red and green primary colors to achieve color display.
Although its cost may be relatively low, it cannot compare with full-color LED display in terms of display effect and color expression.
In summary, there are significant differences between full-color LED display and dual-color LED display in terms of color composition, display effect, application field and technical characteristics.
When choosing, it is necessary to consider comprehensively according to specific application requirements and budget.
