Currently only a few companies have genuine software. It is illegal to use piracy now.
As long as the control system supports it, the universal driver chip can also achieve point-by-point correction!
LED electronic display is widely used in our lives. Maybe everyone has a simple understanding of LED electronic display, but is it really more in-depth understanding? Today, Xiao Bian clarifies and discusses the concepts of several common misunderstandings of LED electronic displays.
First, LED electronic display software is not free
Second, point-by-point calibration does not require the use of a dedicated driver chip
Third, the chromaticity correction is not equal to the chromaticity uniformity correction, and the application of the chromaticity correction is more the conversion of the gamut space. Under normal circumstances, after the brightness correction, the brightness uniformity of the display can reach a very high level. With the color gamut space correction, the color fidelity of the display can reach a very high level. Chroma correction and chroma uniformity correction:
1. Chroma Correction: Meets the customer's special requirements for display gamut space: Corrects the display gamut space to the customer-specified color space. Improve the color fidelity of the display to make color reproduction more realistic: correct the display gamut space to standard color spaces such as SRGB, NTSC.
2, chromaticity uniformity correction: due to the accuracy and stability of the color separation of the color separation machine, coupled with the effective process of mixing the mixed crystal, the application of chromaticity uniformity correction is quite limited, when cleaning inventory is certain Mix a very small amount of scattered wavelength light on a single screen. The chromaticity uniformity correction is also the only choice at this time. Due to mistakes in the production process, lamps/chips of different wavelengths are mixed together and used on the same screen. Chromaticity uniformity correction can be used as a last resort.
Fourth, point-by-point correction is not done by the control system manufacturer. The correction technology is not bundled with the control system. The real necessary conditions for point-by-point correction are:
1. A control system that can achieve point-by-point correction.
2. High-precision, high-efficiency lamp point brightness collection equipment. Summary: Point-by-point drive control has already been realized, and this function is already available in the general control system on the market. But for the collection of millions of light point data, some control system vendors have developed tools that are incompatible with other systems. As a result, the point-by-point correction and control system is bundled, and the integrated understanding is misunderstood.
Five, the gray level of the LED electronic display
Grayscale as a dual primary and full color display is an important indicator. The current market is flooded with 16-level and 64-level grayscale displays that pretend to be 256 shades of gray. Its control cost is only 1/5 of the control of 256 levels of gray. The simple way is to play a VCD of a more intense sports scene to see if it can be seen clearly on the led electronic display.
