1. Maximum brightness
No explicit feature requirement for the important performance of maximum brightness
2. Primary wavelength error of base color
The main wavelength error index of primary color is changed from "base wavelength error" to "primary wavelength error", which can explain what is a characteristic of LED display.
3. Duty-free ratio
As described above, "performance principle" as long as possible, requirements should be expressed by performance characteristics rather than by design and description, and this method leaves the greatest scope for technological development. We believe that the "duty ratio" is a purely design technology requirements, should not be used as an indicator of LED display product standards of a performance index
4. Refresh Frequency
From the measurement method, it seems to ignore the user really concerned about the problem, it also did not take into account the various manufacturers used in the driver IC, drive circuit and different methods, causing the difficulty of testing
