In the design and manufacturing process of LED display screens, clarifying the requirements for brightness and point density is crucial to determining the brightness of a single tube. However, the specific method of computer single-tube brightness may vary depending on different application scenarios, display technologies, and characteristics of the LED chips used. The following are general steps that can be used as a reference:
1. Determine the overall brightness requirements: First, determine the overall brightness required for the display based on the usage environment and viewing distance of the LED display. This usually involves factors such as the influence of ambient light, the viewer's visual experience, and the clarity requirements of the display.
2. Calculate dot density and area: According to the dot density requirements and the predetermined size of the display screen, calculate the total number of dots and total area of the display screen. Point density is usually expressed as the number of points per unit area, such as "points/㎡".
3. Determine the coverage area of a single LED tube: Based on the module design and pixel spacing of the display screen, determine the area covered by each LED single tube (or pixel). This depends on the physical structure of the display and how the pixels are arranged.
4. Allocate brightness: Based on the overall brightness requirement and the area covered by each single tube, calculate the brightness that each single tube needs to contribute. This usually involves distributing the overall brightness needs evenly to each pixel or individual tube.
5. Consider light efficiency and loss: When calculating the brightness of a single tube, you also need to consider factors such as the light efficiency of the LED chip, light loss (such as light loss due to reflection, absorption, etc.), and the efficiency of the drive circuit. These factors affect the actual brightness emitted.
6. Adjustment and optimization: Finally, based on the actual display effect and test results, make necessary adjustments and optimizations to the single-tube brightness to ensure that the overall brightness and visual effects of the display meet the requirements.
It should be noted that the above steps only provide a rough framework. The actual calculation process may be more complex and may require the help of professional software or tools. In addition, different LED chips, packaging methods and drive circuits will also affect the brightness of a single tube, so these factors need to be considered when calculating.
If you need more specific calculation methods and data, it is recommended to consult the manufacturer of the LED display or a professional display technology engineer. They can provide more accurate guidance and suggestions based on your specific needs and the technical parameters of the display.
