Kuti uwane yakanakisa kuratidza maitiro, emhando yepamusoro ma LED ekuratidza masikirini kazhinji anofanirwa kuverengerwa kupenya uye ruvara, kuitira kuti kupenya uye kuenderana kweruvara kweLED kuratidza sikirini mushure mekuvhenekesa kumusoro kunogona kusvika kune yakanyanya kunaka.Saka nei yemhando yepamusoro-soro yekuratidzira ye LED ichida kuverengerwa, uye inoda kuverengerwa sei?

Chekutanga, zvinodikanwa kuti unzwisise hunhu hwekutanga hwekuona kweziso remunhu kupenya.Kupenya chaiko kunoonekwa neziso remunhu hakuna kuenderana nemutsara nekupenya kunoburitswa neChiratidziro che LED, asi pane hukama husiri hwemutsara.
Semuyenzaniso, kana ziso remunhu richitarisa chidzitiro che LED chine kupenya chaiko kwe1000nit, tinodzikisa kupenya kusvika pa500nit, zvichikonzera kudzikira kwe50% mukupenya chaiko.Zvisinei, kupenya kunoonekwa kweziso remunhu hakudzike zvakatevedzana kusvika pa50%, asi kusvika pa73%.
Mutsara usiri wemutsetse pakati pekupenya kunoonekwa kweziso remunhu uye kupenya chaiko kweiyo LED skrini yekuratidzira inonzi gamma curve (sezvinoratidzwa muFigure 1).Kubva pane gamma curve, zvinogona kuoneka kuti maonero ekupenya anochinja neziso remunhu anoenderana, uye iyo chaiyo amplitude yekupenya inoshanduka pazviratidziro zve LED haina kuenderana.

Tevere, ngatidzidzei nezve hunhu hwekuona kweruvara shanduko muziso remunhu.Mufananidzo 2 iCIE chromaticity chati, uko mavara anogona kumiririrwa neruvara makongiresi kana chiedza wavelength.Semuenzaniso, kureba kweyakajairwa LED kuratidza sikirini 620 nanometers kune tsvuku LED, 525 nanometers yegirinhi LED, uye 470 nanometers yeblue LED.
Kazhinji kutaura, munzvimbo yeruvara rwakafanana, kushivirira kweziso remunhu pamusiyano weruvara ndiko Δ Euv = 3, inozivikanwawo sekusiyana kwemavara kunoonekwa.Kana musiyano wemavara pakati pe LEDs uri pasi peukoshi uhwu, zvinoonekwa sekuti musiyano hauna kukosha.Kana Δ Euv> 6, inoratidza kuti ziso remunhu rinoona musiyano wakakura wemavara pakati pemavara maviri.
Kana kuti zvinotendwa kuti kana musiyano wewavelength wakakura kupfuura 2-3 nanometers, ziso remunhu rinokwanisa kuona musiyano weruvara, asi kunzwisiswa kweziso remunhu kune mavara akasiyana kuchiri kusiyana, uye musiyano wewavelength uyo ziso remunhu rinogona kuona. nokuti mavara akasiyana-siyana haana kugadziriswa.
Kubva pakuona kwekusiyana kwemaitiro ekupenya uye ruvara neziso remunhu, ma LED ekuratidzira masikirini anofanirwa kudzora mutsauko wekupenya uye ruvara mukati mechikamu icho ziso remunhu risingaone, kuitira kuti ziso remunhu rinzwe zvakanaka kuenderana mukupenya uye ruvara kana uchiona LED kuratidza skrini.Kupenya uye ruvara rwemhando yemidziyo yekurongedza ye LED kana machipisi e LED anoshandiswa mumaratidziro e LED ane simba rakakura pakuenderana kwechiratidziro.

Paunenge uchigadzira zviratidziro zve LED, midziyo yekurongedza ye LED ine kupenya uye wavelength mukati meimwe renji inogona kusarudzwa.Semuenzaniso, midziyo ye LED ine kupenya span mukati me10% -20% uye wavelength renji mukati me3 nanometers inogona kusarudzwa kugadzirwa.
Kusarudza midziyo ye LED ine hutete hwekupenya uye wavelength inogona kunyatso simbisa kuenderana kweiyo skrini yekuratidzira uye kuwana mhedzisiro yakanaka.
Nekudaro, kupenya kwemhando uye wavelength renji yemidziyo yekurongedza ye LED inowanzoshandiswa mumagetsi ekuratidzira e LED inogona kunge yakakura kupfuura iyo yakatarwa yataurwa pamusoro, izvo zvinogona kuguma nekusiyana kwekupenya uye ruvara rwe LED mwenje-emitting chips ionekwe neziso remunhu. .
Chimwe chiitiko ndeye COB kurongedza, kunyangwe iyo iri kuuya kupenya uye wavelength ye LED mwenje-emitting machipisi inogona kudzorwa mukati meiyo yakanakira renji, inogona zvakare kutungamira mukusaenderana kupenya uye ruvara.
Kuti ugadzirise kusawirirana uku mu LED kuratidza skrini uye kuvandudza kunaka kwekuratidzira, point by point correction technology inogona kushandiswa.
Kururamisa pfungwa neimwe pfungwa
Point by point kururamisa ndiyo maitiro ekuunganidza kupenya uye chromaticity data kune yega pixel sub pixel paneChiratidziro che LED, ichipa gadziriso coefficients yega yega base color sub pixel, uye kuvadyisa kudzosera kune yekudzora sisitimu yechiratidziro.Iyo yekudzora sisitimu inoshandisa ma coefficients ekugadzirisa kutyaira misiyano yega yega yega yemavara sub pixel, nekudaro ichivandudza kufanana kwekupenya uye chromaticity uye kuvimbika kweruvara rwechiratidziro.
Summary
Maonero ekupenya kwekuchinja kwe LED machipi neziso remunhu anoratidza hukama husina mutsara neiyo chaiyo kupenya shanduko ye LED chips.Goko iri rinonzi gamma curve.Kunzwa kweziso remunhu kune akasiyana wavelengths eruvara kwakasiyana, uye ma LED ekuratidzira masikirini ane zvirinani kuratidza maitiro.Kupenya uye kusiyanisa kwemavara kwechidzitiro chekuratidzira kunofanirwa kudzorwa mukati mechikamu icho ziso remunhu risingakwanise kuziva, kuitira kuti ma LED anoratidza masikirini aratidze kuenderana kwakanaka.
Kupenya uye wavelength yeLED yakarongedzwa zvishandiso kana COB yakarongedzerwa LED mwenje-emitting machipisi ane humwe huwandu.Kuti ive nechokwadi chekuenderana kwakanaka kwe LED kuratidza zviratidziro, point by point yekururamisa tekinoroji inogona kushandiswa kuwana kupenya kunoenderana uye chromaticity yemhando yepamusoro yemhando yekuratidzira LED skrini uye kuvandudza kunaka kwekuratidzira.
