春天万物复苏，在蓝天的辉映下，绿草青青;秋天麦浪滚滚;在阳光的普照下，一片金黄。五颜六色的大自然是那么的夸姣，迷惘的是现有的 山东LED显示屏http://www.ledky.com闪现屏无法彻底再现这夸姣的风光。LED尽管归于单色光，可是各色LED依然有30~50nm左右的半波宽，因而其色饱和度是有限的。
Recovery of all things spring, in the blue sky shine, green grass green; autumn wheat billowing; in the sunshine, golden. Be riotous with colour nature is so beautiful, lost is the LED flash screen can not be completely reproduced this beautiful scenery. Although LED to monochromatic light, but still with LED about 30~50nm half wave width, so the color saturation is limited.
在大自然界色彩极为丰厚的黄色和青色区域LED电子显示屏的色饱和度是严厉短少的。
In the great nature color for color saturation full color rich yellow and cyan area LED is the severe shortage.
这些年，在平板闪现范畴热衷于谈论3+3多基色闪现(红、绿、蓝加黄、青、紫)，以拓展色域，再现更为丰厚的自然界色彩。那么，LED闪现屏可否结束3+3多基色闪现?
These years, in the flash category is keen to talk about 3+3 multi colors (red, green, blue flashes with yellow, green, purple), in order to expand reproduction gamut, more generous nature color. Then, LED flash screen can end the 3+3 multi primary?
咱们晓得在可见光范围内，黄、青为单色光，咱们已具有高饱和度的黄色、青色LED。LED电子显示屏而紫色为复色光，单芯片紫色LED则是不存在的。尽管咱们无法结束红、绿、蓝加黄、青、紫3+3多基色LED闪现屏。可是，研讨红、绿、蓝加黄、青3+2多基色LED闪现屏却是可行的。因为自然界存在很多高饱和度的黄色和青色;因而，该项研讨是有必定价值的。
We know that in the range of visible light, yellow, green for the monochromatic light, we have high saturation of yellow, cyan LED. While purple for polychromatic light purple, single chip LED is not exist. Although we can not be the end of the red, green, blue and yellow, green, violet 3+3 multi primary LED display screen. But the study of red, green, blue, yellow, and green 3+2 multi primary LED flash screen is feasible. Because there are a lot of high saturation of yellow and blue; therefore, this study is a certain value.
在现行的各种电视规范中，LED电子显示屏视频源只需红绿蓝三基色，而没有黄、青二色。那么，闪现终端黄、青二基色怎么驱动?其实，在断定黄、青二基色驱动强度时;咱们因遵从以下三点准则：
In a variety of television in the video source code, only the red green and blue three primary colors, yellow, green two color without. So, yellow, green two color flash terminal how to drive? Actually, in that yellow, green two color driving strength; we have to follow the three principles:
(1)添加黄、青二基色的意图是为了拓展色域，然后行进色饱和度。而整体亮度值不能改动;
(1) intended to add yellow, green two color is to expand the color gamut color saturation, and then go. While the overall brightness value can not be changed;
(2)在行进色饱和度的一起，不得改动色彩;
(2) in advance of color saturation, shall not change color;
(3)以D65为中间;以RYGCB色域间隔为端点，在色域范围内各点作线性拓展。
(3) with D65 as the middle; RYGCB color gamut interval endpoints, in color gamut range of each point in the linear expansion.
LED显示屏在上述三准则的指导下;按重力中间规矩，咱们能够找到3+2多基色色度处置办法。可是，要想真实结束3+2多基色全彩屏，咱们还要打败黄、青色LED亮度短少;成本上升较大等艰难，其时仅限于理论谈论。
In the above three standards under the guidance; according to the gravity center of rules, we can find 3+2 multi primary color solution. But, to the real end 3+2 Gezer full-color, we will defeat the yellow, cyan LED brightness shortage; the difficult rise in the cost, time is limited to theoretical talk.
