如今无论是在大街的 山东LED显示屏，第一、在保证光频朴实的前提下，央求红、绿、蓝光强之比有必要靠近3：6：1;第二、因为咱们视觉对赤色的敏感性，央求赤色发光源在空间上要松散分布;第三、因为咱们视觉对红、绿、蓝三种色彩光强的异常的非线性曲线照应，央求异常光强的白光对红、绿、蓝要进行类似电视机里的γ校正;第四、人的视觉对色差的分辩才干有限。因此有必要找出图像色彩再现实在性的客观方针。如今的 山东LED显示屏的使用量是适当的广泛，一定要学会其正确的复原办法。 Now, whether in the street, first, in order to ensure the optical frequency plain, begged red, green, Lan Guangqiang is necessary to close to 3:6:1; second, because of the sensitivity of our vision to red, red light source in the space requirements to loose distribution; third, because our vision to red, green, blue three color intensity anomaly of non-linear curve coordinate, begged the anomaly intensity of white light similar TV gamma correction on the red, green, and blue to; fourth, human vision of color resolution to co.. Therefore, it is necessary to find out the image color reproduction is the objective principle. Use Shandong LED display now is suitable widely, must learn the correct restoration measures.
1. 红、绿、蓝三色的波长应分别为：660nm、525nm、470nm左右;
1 red, green, and blue wavelengths are: 660nm, 525nm, 470nm;
2. 选用4管单德配白光为佳(多管单元也能够，取决于光强);
In 2 selected 4 single tube in Germany with white light is better (multi unit can also be determined, Yu Guangqiang);
3. 红、绿、蓝三色的灰度级为256级;
In the 3 gray level in red, green, blue 256;
4. 有必要选用对准LED像素管的非线性校正。
In 4 it is necessary to use the nonlinear alignment in LED pixel tube correction.
