春天萬物復(fù)蘇，在藍(lán)天的輝映下，綠草青青;秋天麥浪滾滾;在陽光的普照下，一片金黃。五顏六色的大自然是那么的夸姣，迷惘的是現(xiàn)有的 山東LED顯示屏http://m.vipgo8.com閃現(xiàn)屏無法徹底再現(xiàn)這夸姣的風(fēng)光。LED盡管歸于單色光，可是各色LED依然有30~50nm左右的半波寬，因而其色飽和度是有限的。
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.
在大自然界色彩極為豐厚的黃色和青色區(qū)域LED電子顯示屏的色飽和度是嚴(yán)厲短少的。
In the great nature color for color saturation full color rich yellow and cyan area LED is the severe shortage.
這些年，在平板閃現(xiàn)范疇熱衷于談?wù)?+3多基色閃現(xiàn)(紅、綠、藍(lán)加黃、青、紫)，以拓展色域，再現(xiàn)更為豐厚的自然界色彩。那么，LED閃現(xiàn)屏可否結(jié)束3+3多基色閃現(xiàn)?
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?
咱們曉得在可見光范圍內(nèi)，黃、青為單色光，咱們已具有高飽和度的黃色、青色LED。LED電子顯示屏而紫色為復(fù)色光，單芯片紫色LED則是不存在的。盡管咱們無法結(jié)束紅、綠、藍(lán)加黃、青、紫3+3多基色LED閃現(xiàn)屏�？墒�，研討紅、綠、藍(lán)加黃、青3+2多基色LED閃現(xiàn)屏卻是可行的。因?yàn)樽匀唤绱嬖诤芏喔唢柡投鹊狞S色和青色;因而，該項(xiàng)研討是有必定價(jià)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.
在現(xiàn)行的各種電視規(guī)范中，LED電子顯示屏視頻源只需紅綠藍(lán)三基色，而沒有黃、青二色。那么，閃現(xiàn)終端黃、青二基色怎么驅(qū)動(dòng)?其實(shí)，在斷定黃、青二基色驅(qū)動(dòng)強(qiáng)度時(shí);咱們因遵從以下三點(diǎn)準(zhǔn)則：
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)添加黃、青二基色的意圖是為了拓展色域，然后行進(jìn)色飽和度。而整體亮度值不能改動(dòng);
(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)在行進(jìn)色飽和度的一起，不得改動(dòng)色彩;
(2) in advance of color saturation, shall not change color;
(3)以D65為中間;以RYGCB色域間隔為端點(diǎn)，在色域范圍內(nèi)各點(diǎn)作線性拓展。
(3) with D65 as the middle; RYGCB color gamut interval endpoints, in color gamut range of each point in the linear expansion.
LED顯示屏在上述三準(zhǔn)則的指導(dǎo)下;按重力中間規(guī)矩，咱們能夠找到3+2多基色色度處置辦法�？墒牵胝鎸�(shí)結(jié)束3+2多基色全彩屏，咱們還要打敗黃、青色LED亮度短少;成本上升較大等艱難，其時(shí)僅限于理論談?wù)摗?
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.
