Iwo mana makuru maratidziro e LED kuratidza:

P10 yekunze inotungamira kuratidzwa

1. Kupenya kwakanyanya

Hapana chakajeka chinodiwa chinodiwa pakuita kwakakosha kwe "kupenya kwakanyanya". Nekuda kwekuti nharaunda yekushandisa ye LED kuratidza skrini yakasiyana zvakanyanya, iyo mwenje (kureva, ambient kupenya kunodaidzwa nevanhuwo zvavo) kwakasiyana. Naizvozvo, kune zvakawanda zvakaomesesa zvigadzirwa, sekureba nzira dzinoenderana dzekuedza dzakatsanangurwa muyero, mutengesi anozopa data rekuita. Iyo (yechigadzirwa ruzivo) rondedzero iri nani pane chaiyo yekuita zvinodiwa zvinopihwa muyero. Izvi zvose zvinoenderana nemitemo yenyika, asi izvi zvinotungamirirawo kukuenzanisa kusingagoneki mukubhidha, uye vashandisi havanzwisisi izvi, kuitira kuti "kupenya kwakanyanya" kunodiwa mumagwaro akawanda ekubhidha kunowanzova kwakanyanya kudarika kudiwa chaiko. Naizvozvo, zvinokurudzirwa kuti kutungamira vashandisi kuti vanzwisise nenzira kwayo indekisi yekuita kwe "kupenya kwakanyanya" kweiyo LED kuratidzwa, zvinodikanwa kuti indasitiri ipe gwara: mune dzimwe nguva, munzvimbo yekushandiswa kwechiedza chakasiyana, kupenya kwe LED kuratidza kunosvika kune imwe kukosha. inogona kuzadzisa zvinodiwa.

2. Primary color dominant wavelength kukanganisa

Shandura iyo yekutanga color dominant wavelength kukanganisa index kubva ku "primary color wavelength kukanganisa" kuenda ku "primary color dominant wavelength kukanganisa", iyo inogona kutsanangura zvirinani maitiro anoratidzwa nechiratidzo ichi pakuratidzira kwe LED. Iyo yakakura yewavelength yeruvara yakaenzana neruvara rweruvara rwunocherechedzwa neziso remunhu, inova huwandu hwepfungwa uye hunhu hunosiyanisa mavara kubva kune mumwe nemumwe. Izvo zvinodikanwa zvekuita zvinotsanangurwa neiyi indasitiri chiyero, chaizvo, vashandisi havanzwisise kuti chiratidzo chinoratidza kufanana kwemavara kweiyo LED kuratidza. Naizvozvo, isu tinofanirwa kutungamira vashandisi kuti vanzwisise izwi rekutanga, tozonzwisisa chiratidzo ichi? Kana kuti tinofanira kutanga taziva uye kunzwisisa chiratidziro che LED kubva pamaonero emutengi, tobva tapa zviri nyore kunzwisisa maitiro ekuita ayo vashandisi vanogona kunzwisisa?

Imwe yemisimboti mukuumbwa kwezviyero zvechigadzirwa "Performance Principle": "Nesezvinobvira, zvinodiwa zvinofanirwa kuratidzwa nemaitiro ekuita kwete magadzirirwo nematsanangudzo, uye nzira iyi inosiya mukana mukuru webudiriro yetekinoroji." "Wavelength kukanganisa" ndiyo inodikanwa yekugadzira. Kana ikatsiviwa ne "kufanana kwemavara", hapana LED ine wavelength shoma. Kune vashandisi, chero iwe uchinge waona kuti ruvara rwechiratidziro che LED yunifomu, haufanirwe kufunga kuti unoishandisa Ndeipi nzira yehunyanzvi yekuwana, siya nzvimbo yakawanda sezvinobvira yekuvandudza tekinoroji, iyo inobatsira zvikuru kuvandudzwa kweindasitiri.

3. Duty kutenderera

Sezvakangoita "Performance Principle" yataurwa pamusoro, "Sezvinobvira, zvinodiwa zvinofanirwa kuratidzwa nemaitiro ekuita kwete magadzirirwo nematsanangudzo, uye nzira iyi inosiya nzira huru yekuvandudza tekinoroji". Isu tinotenda kuti "kugara "Ratio" inongova chinodiwa chekugadzira tekinoroji uye haifanirwe kushandiswa sechiratidzo chekuita kwe LED kuratidza zvigadzirwa zviyero; isu tese tinoziva kuti chero mushandisi ane hanya nezve kutyaira basa kutenderera kwechiratidziro chekuratidzira, vane hanya nezve mhedzisiro yechiratidziro, pane kuita kwedu kwehunyanzvi hwekuita; sei isu tichigadzira zvipingamupinyi zvakadaro zvehunyanzvi isu pachedu kudzikamisa kusimukira kwehunyanzvi hweindasitiri?

4. Refresh rate

Kubva pakuona kwemaitiro ekuyera, zvinoita sekunge isingatarisi zvinonetsa zvevashandisi, uye zvakare haifungi nezve dzakasiyana siyana dzekutyaira IC, kutyaira matunhu uye nzira dzinoshandiswa nevagadziri vakasiyana, zvichikonzera kuomerwa mukuyedzwa. Semuenzaniso, iyo yakazara-ruvara skrini yekubhidha yeShenzhen Stadium, mune yekuenzanisira bvunzo yenyanzvi, kuyedzwa kwechiratidzo ichi kunounza matambudziko mazhinji. "Refresh frequency" ndiyo inodzokororwa yenguva inodiwa kuratidza furemu yechidzitiro, uye skrini yekuratidzira inoonekwa semwenje sosi, ndiko kuti, kupenya kwenzvimbo yechiedza. Isu tinokwanisa kuyedza zvakananga kubhururuka kwakawanda kweiyo mwenje sosi yechiratidziro nechiridzwa chakafanana ne "photosensitive frequency mita" kuratidza chiratidzo ichi. Isu takaita bvunzo iyi tichishandisa oscilloscope kuyera iyo LED drive ikozvino waveform yechero ruvara kuona iyo "refresh frequency", iri 200Hz pasi pemunda chena; pasi peyakaderera grey mazinga akadai se 3-level grey, iyo yakayerwa frequency yakakwira se200Hz. Zvinopfuura gumi k Hz, uye kuyerwa nePR-650 spectrometer; hazvina mhosva mundima chena kana grey level ye200, 100, 50, zvichingodaro, flicker frequency yeyakayerwa sosi yemwenje i200 Hz.

Waini yakaita sedhiramu rekugadzira led kuratidza muZhongshan, China

Aya mapoinzi ari pamusoro angori tsananguro pfupi yehunhu hweakawanda ma LED anoratidza. Kunewo akawanda "hupenyu hwekushanda", "nguva inoreva pakati pekukundikana", nezvimwewo zvakasangana mukubhidha. Iko hakuna nzira yekuyedza inogona kushandiswa munguva pfupi. Nguva yekuona kana iyo LED inoratidzira inosangana nezvinodiwa zvekugadzikana, kuvimbika kana hupenyu; izvi zvinodiwa hazvifanirwe kutaurwa. Mugadziri anogona kuita vimbiso, asi haigone kutsiva chinodiwa. Iyo ipfungwa yebhizinesi, chibvumirano chechibvumirano, kwete tekinoroji pfungwa. Iyo indasitiri inofanirwa kuve nekutaura kwakajeka pane izvi, izvo zvichave zvakanyanya kubatsira kune vashandisi, vagadziri uye indasitiri yese.

Kana iri nzira yekutungamira vashandisi kuti vanzwisise nenzira kwayo chigadzirwa cheiyo yakaoma sisitimu sekuratidzira kwe LED, zvichiri kudikanwa kuti masangano emaindasitiri abate mamwe maforamu ekuratidzira tekinoroji ye LED, uye kuongorora chigadzirwa ichi kubva mumaonero evashandisi uye kutungamira vashandisi kuita nemazvo. kunzwisisa kuratidzwa kwe LED. .
