Description of brightness discrimination levels
- 1.Definition of brightness discrimination level: The brightness discrimination level of transparent LED display refers to the brightness level from darkest to brightest that the human eye can distinguish. Although the grayscale level of transparent screen can be as high as 256 or 1024, due to the limited sensitivity of human eye to brightness, it is actually impossible to fully distinguish all grayscale levels. Even if the screen supports many grayscale levels, the human eye may not be able to distinguish some subtle changes.
- 2.Human eye discrimination ability : The human eye’s ability to discern brightness varies from person to person, so not all grayscale levels can be clearly discerned by everyone. In fact, many adjacent grayscale levels may not look very different. This means that although the display may support high grayscale levels, the actual brightness discrimination level depends on the sensitivity of the human eye.
- 3.Test standards and applications: The brightness discrimination level can be tested through special software or equipment. Generally speaking, transparent displays that reach level 20 or above are considered to have good brightness discrimination capabilities. Higher brightness discrimination levels can provide richer brightness changes and expand the color space of the display, thereby improving the delicacy of the display effect and visual experience.
Description of Grayscale Recognition Levels
- 1. Basic definition of grayscale : The grayscale of LED transparent display is determined by the number of A/D conversion bits of the system, which directly affects the color performance of the display. Specifically, the grayscale represents the number of different brightness levels that the screen can display. The system’s video processing chip, memory and transmission system must support the corresponding number of bits to achieve these grayscale levels.
- 2.Domestic and international grayscale standards: In the domestic market, LED displays usually use an 8-bit processing system that supports 256 grayscale levels. In this way, there are 256 brightness changes from black to white, and the combination of RGB primary colors can generate about 16.77 million colors, or 16.7 million colors. In contrast, international brands mostly use a 10-bit processing system that can display 1024 grayscale levels. The combination of RGB primary colors can produce 1.07 billion colors, providing higher color accuracy and fineness.
- 3. The impact of grayscale on display effects : A high grayscale level means that the display can present more delicate color transitions and richer image details. An 8-bit system is sufficient to meet most application requirements, but for professional fields that require higher color accuracy, a 10-bit system can provide more accurate color performance. Choosing the right grayscale level can improve the display effect and meet the needs of different application scenarios.
in conclusion
In practical applications, the brightness discrimination level is crucial to the image quality and user experience of the display. A higher brightness discrimination level can make the image more vivid and realistic, and enhance the visual experience. Therefore, when choosing a transparent LED display, it is necessary to pay attention to two key technical parameters: brightness and grayscale. Brightness affects the brightness of the screen, while grayscale determines the richness and delicateness of the color. Taking these two factors into consideration can help meet the needs of different application scenarios.
