Chiratidziro che LED chigadziro chinoshandisa chiedza-emitting diodes (LEDs) sezvinhu zvinobudisa chiedza kuratidza mifananidzo, mavhidhiyo, mifananidzo uye mamwe mashoko kuburikidza nemagetsi emagetsi. Chiratidziro che LED chine zvakanakira kupenya kwakanyanya, kuderera kwesimba rekushandisa, hupenyu hurefu, kureba yekuona kona, nezvimwewo, uye inoshandiswa zvakanyanya mukati nekunze kushambadzira, chekufambisa, mitambo, varaidzo yetsika nemimwe minda. Kuti uve nechokwadi chekuratidzira uye simba rekuchengetedza simba reiyo LED skrini yekuratidzira, zvinodikanwa kuverenga iyo skrini nzvimbo uye kupenya zvine musoro.
1. Nzira yekuverenga iyo skrini nzvimbo ye LED kuratidza skrini
Iyo skrini yenzvimbo yekuratidzira kwe LED inoreva saizi yenzvimbo yayo inobudirira yekuratidzira, kazhinji mumamita emamita. Kuti uverenge iyo skrini yenzvimbo yekuratidzira kwe LED, zvinotevera paramita dzinoda kuzivikanwa:
1. Dot spacing: nhambwe yepakati pakati pepikisi imwe neimwe nemapikisi akatarisana, kazhinji mumamirimita. Iyo idiki iyo dot pitch, iyo yakakwira pixel density, iyo yakakwirira resolution, inojekesa mhedzisiro yekuratidzira, asi kukwira kwemutengo. Iyo dot pitch inowanzotemerwa zvinoenderana neiyo chaiyo application mamiriro uye yekuona kureba.
2. Module size: yega yega module ine akati wandei mapixels, inova ndiyo yakakosha unit ye LED kuratidza. Saizi yemodule inotarwa nenhamba yemapixels akatwasuka uye akatwasuka, kazhinji mumasendimita. Semuenzaniso, P10 module inoreva kuti module yega yega ine 10 pixels yakatwasuka uye yakatwasuka, kureva, 32×16=512 pixels, uye saizi yemodule i32×16×0.1=51.2 square centimeters.
3. Kukura kweScreen: Iyo yose ye LED inoratidzira inoparadzaniswa nemamodule akawanda, uye ukuru hwayo hunotaridzirwa nehuwandu hwemamodule akatwasuka uye akatwasuka, kazhinji mumamita. Semuenzaniso, P10 yakazara-ruvara sikirini ine hurefu hwemamita mashanu uye kureba kwemamita matatu zvinoreva kuti kune 50/0.32=156 mamodule mugwara rakachinjika uye 30/0.16=187 mamodule munzira yakatwasuka.
2. Nzira yekuverenga kupenya kwe LED kuratidza
Kupenya kwechiratidziro che LED kunoreva kusimba kwechiedza chainoburitsa mune mamwe mamiriro, kazhinji mu candela pa square mita (cd/m2). Iyo yakakwirira kupenya, kusimba kwechiedza, kunowedzera kusiyanisa, uye kusimba kwekusakwanisa kupindira. Kupenya kunowanzo kutsanangurwa zvinoenderana nechaiyo application nharaunda uye yekuona kona.
1. Kupenya kwemwenje we LED imwe chete: chiedza chechiedza chinobudiswa nemuvara wega wega we LED mwenje, kazhinji mu millicandela (mcd). Kupenya kwechiedza chimwe chete che LED kunotarirwa nezvinhu zvayo, maitiro, ikozvino uye zvimwe zvinhu, uye kupenya kwemarambi e LED emarudzi akasiyana kwakasiyanawo. Semuenzaniso, kupenya kwemarambi matsvuku e LED anowanzo 800-1000mcd, kupenya kwegirinhi mwenje we LED kunowanzo 2000-3000mcd, uye kupenya kwebhuruu LED mwenje kazhinji 300-500mcd.
2. Kupenya kwepikseli yega yega: Pixel yega yega inoumbwa nemwenje we LED akati wandei emavara akasiyana, uye kusimba kwechiedza kunoburitswa naro ndiko kuwanda kwekupenya kwemavara ega ega mwenje we LED, kazhinji mu candela (cd) sechikamu. Kupenya kwepixel yega yega kunotariswa nekuumbwa kwayo uye chiyero, uye kupenya kwepixel yega yega yemhando dzakasiyana dze LED kuratidza kwakasiyanawo. Semuenzaniso, pixel yega yega yeP16 yakazara-ruvara skrini ine 2 tsvuku, 1 yegirini, uye 1 bhuruu LED mwenje. Kana 800mcd tsvuku, 2300mcd yegirini, uye 350mcd bhuruu LED mwenje yakashandiswa, kupenya kwepikisi imwe neimwe ndeye (800×2 +2300+350)=4250mcd=4.25cd.
3. Kubwinya kwese kwechidzitiro: chiedza chechiedza chinobudiswa ne LED yose inoratidzirwa ihuwandu hwekupenya kwemapikseli ose akakamurwa nenzvimbo yekrini, kazhinji mu candela pa square mita (cd / m2) sechikwata. Kupenya kwese kwechidzitiro kunotarwa nekugadziriswa kwayo, scanning mode, kutyaira ikozvino uye zvimwe zvinhu. Mhando dzakasiyana dze LED kuratidza skrini dzine kwakasiyana kupenya kwese. Semuyenzaniso, resolution pa square yeP16 yakazara-ruvara skrini ndeye 3906 DOT, uye nzira yekuongorora ndeye 1/4 scanning, saka kupenya kwayo kwakanyanya ndeye (4.25×3906/4)=4138.625 cd/m2.
3. Pfupiso
Ichi chinyorwa chinosuma nzira yekuverenga nharaunda uye kupenya kweiyo LED kuratidza skrini, uye inopa inoenderana mafomula nemienzaniso. Kuburikidza nenzira idzi, yakakodzera LED kuratidza paramita inogona kusarudzwa zvinoenderana nezvinodiwa chaizvo uye mamiriro, uye mhedzisiro yekuratidzira uye simba rekuchengetedza simba rinogona kugadziridzwa. Ehe, mukushandisa zvinoshanda, zvimwe zvinhu zvinoda kutariswa, sekukanganisa kwechiedza chemukati, tembiricha uye humidity, kupisa kupisa, nezvimwewo pakuita uye hupenyu hweiyo LED kuratidza.
Kuratidzwa kwe LED ibhizinesi rakanaka kadhi munharaunda yanhasi. Haikwanise kuratidza ruzivo chete, asiwo kuendesa tsika, kugadzira mamiriro uye kuwedzera mufananidzo. Nekudaro, kuti uwane iyo yakanyanya mhedzisiro yeratidziro ye LED, zvinodikanwa kubata dzimwe nzira dzekuverenga, zvine musoro dhizaini uye sarudza iyo skrini nzvimbo uye kupenya. Nenzira iyi chete tinogona kuona kuratidzwa kwakajeka, kuchengetedza simba, kuchengetedza kwezvakatipoteredza, kusimba uye hupfumi.
