        Performance analysis of the four LED display

        Maximum brightness

        For the "maximum brightness" did not give this important performance characteristics of specific requirements. Because the use of the environment vary widely LED display, illumination (that is, most people said ambient light) is not the same, so, for the most complex products, as long as the standards specified in the corresponding test method, a performance by the supplier to provide data (Product Information) than the standard given in the list of the specific performance requirements better. These are in line with international standards, but it also resulted in unrealistic bids in competition with each other comparisons, users have not understood, resulting in a number of tenders called for "maximum brightness" is often far higher than the actual need. It is therefore recommended in order to guide users to the correct understanding of LED display of the "maximum brightness" this performance, the industry is necessary to give a guide: In some cases, the use of different illumination conditions, LED display's brightness to what value meet the requirements.

         

        Primary color wavelength error

        Wavelength error indicator will be the main color, from the "color wavelength error" changed to "primary-color wavelength error" better able to explain this indicator reflect what features an LED display. The main color of the human eye is equivalent to the observed wavelength of the color hue, is a mental capacity, is an attribute to distinguish between colors. And the industry standard performance requirements, literally, the user is unable to understand that it reflects the color uniformity of LED display an indicator. Therefore, is to guide users to first figure out the term, and then understand this indicator? First, from the customer's point of view or to know and understand LED display, and then give the user easy to understand to understand the performance characteristics?

        Product standards developed by one of the principle that the "performance principle": "as long as possible, by the performance characteristics required to express, rather than to express the design and characterization, this approach to technology development leaves room for the largest." "Primary color wavelength error" is a design requirement, if the "color uniformity" instead, there is no limit what the wavelength of LED. For users, as long as you ensure the LED display color is uniform, regardless of what techniques you use to achieve, as large as possible to the technical development left room for the development of such great benefit to the industry.

        Duty cycle

        As mentioned above, the "performance principle" "as long as possible, by the performance characteristics required to express, rather than to express the design and characterization, this approach to technology development leaves room for the largest." We believe that the "duty cycle" is purely a design requirement, should not be used as a standard LED display product performance; we understand, with which the user will care about the display driver duty, they care about the display of results, rather than our technology; why we have created barriers to this technology, limiting the industry's technology development?
