Ukwenzela ukufezekisa ezona ziphumo zibalulekileyo zokubonisa, umgangatho ophakathi we-LEPOST ngokubanzi kufuneka ulawule ukuqaqamba kunye nombala, ukuze ubume kunye nokungqinelana kombala kwesikrini se-LED emva kokufikelela kungcono. Ke kutheni le nto isikrini esikumgangatho ophezulu se-LED esinokulungelelaniswa, kwaye kufuneka njani ukuba silungelelaniswe njani?

Okokuqala, kuyimfuneko ukuqonda iimpawu ezisisiseko zembono yeliso lomntu. Ukuqaqamba okuqinisekileyo okuqondakaliyo kweliso lomntu akuhambelani nokuqaqamba okukhutshwe yiIsikrini se-LED, kodwa ubudlelwane obungapheliyo.
Umzekelo, xa iliso lomntu lijonga isikrini esibonisa i-LED kunye nobuqaqawuli be-1000Nanit, sinciphisa ukuqaqamba ukuya kwi-500NIT, kukhokelela kwi-50% yokukhanya kokukhanya. Nangona kunjalo, ukukhanya okuqondakalayo kweliso lomntu akunciphisi umgca nge-50%, kodwa kuphela kwi-73% kuphela.
Ijika le-non-mgca phakathi kokukhanya kweliso lomntu kunye nobuqaqawuli bokuqaqamba kwe-LED kubizwa ngokuba yi-gamve ye-gamma (njengoko kubonisiwe kumzobo 1). Ukusuka kwijika le-gamma, inokubonwa ukuba umbono wokukhanya otshintsha ngeliso lomntu ubaluleke kakhulu, kwaye olona tshintsho lutshintsho lokukhanya kwimiboniso ye-LED ayingqinelaniyo.

Emva koko, masifunde malunga neempawu zotshintsho lwembono yebala kwiliso lomntu. Umzobo 2 yitshathi yeChie Chietity, apho imibala ingamelwa khona ngokulungelelanisa umbala okanye ukukhanya kwendlela. Umzekelo, i-wavelength yescreen esiqhelekileyo se-LED yi-620 i-nanometers ye-LED ye-LED, i-525 i-nanometers ye-LED ye-LED, kunye ne-470 i-nanometers ye-LED.
Ngokubanzi, kwindawo ye-iyunifomu, ukunyamezelwa kweliso lomntu malunga nomahluko wemibala yi-EUV = 3, kwasaziwa njengomahluko obonakalayo obonakalayo. Xa umbala umahluko phakathi kwe-LEDS ungaphantsi kweli xabiso, kuthathwa ukuba umahluko awubalulekanga. Xa δ EUV> 6, ibonisa ukuba iliso lomntu libona umahluko omkhulu phakathi kwemibala emibini.
Okanye kukholelwa ngokubanzi ukuba xa i-waveleng yabasebenzi ingaphezulu kwe-2-3 i-nanometer, iliso lomntu linokubona umahluko wemibala, kodwa imvakalelo yeliso kwimibala eyahlukileyo isaqondwa.
Ngokwembono yepateni yokukhanya kunye nombala ngeliso lomntu, isikrini esikhokelweyo kufuneka silawule umahluko ekuqaqambekeni kunye neliso lomntu xa sibona isikrini sokubonisa i-LED. Ukukhanya kunye nombala wemibala kwezixhobo zokupakisha ze-LED okanye ii-chips ze-LED ezisetyenziswa kwizikrini zokubonisa ezi-LED zinefuthe elibonakalayo ekubonakalisweni kwesibonisi.

Xa usenza izikrini zokubonisa ezi-LED, izixhobo zokupakisha ezikhoyo ngokukhanya kunye ne-wavelength kuluhlu oluthile zinokukhetha. Umzekelo, izixhobo ze-LED nge-SEFIT SP ngaphakathi kwi-10% -20% kunye ne-Wavelength kunye ne-Eveletth i-3 I-Nanometer inokukhethwa kwimveliso.
Ukukhetha izixhobo ze-LED kunye noluhlu olukhawulezileyo lokuqaqamba kunye ne-wavelength kunokuziqinisekisa ukungqinelana kwesikrini sokubonisa kwaye kufezekise iziphumo ezilungileyo.
Nangona kunjalo, ukuqaqamba kuluhlu kunye nokwaphula uluhlu lwezixhobo zokupakisha ii-LED eziqhele ukusetyenziswa kwizikrini zokubonisa ezi-LED zinokuba zinkulu kunodidi olufanelekileyo olukhankanywe apha ngasentla, olunokubangela i-chips ekhutshelweyo ebonakalayo ebonakalayo.
Enye imeko kukupakisha i-cob, nangona ukukhanya okuzayo kunye nokuqaqamba kokukhanya kwe-LORCIT-PAINT CHINSTE CHIPY I-CHINOS ihlawulwe kuluhlu olufanelekileyo, inokukhokelela ekuqaqambekeni kunye nombala.
Ukusombulula oku kungangqinelani kwizikrini zokubonisa i-LED kunye nokuphucula umgangatho, inqaku leTekhnoloji yokuLungiswa kweNgxelo lingasetyenziswa.
Inqaku ngokulungiswa kwenqaku
Inqaku ngokulungiswa kwenqaku yinkqubo yokuqokelela ukukhanya kunye nedatha ye-chromaticity kwi-pixel nganye engaphantsi kweIsikrini se-LED, ukubonelela ngolungelelwaniso lwe-coerecients kwisiseko se-pixel ye-pixel ye-pixel, kunye nokusondla kwakhona kwinkqubo yokulawula isikrini sokubonisa. Inkqubo yokulawula isebenzisa izixhobo zokulungisa ukuqhuba umahluko kwi-pixel ye-pixel ye-pixel ye-pixel ye-pixel ye-pixel, ngokwenza oko kuphuculwe ukuqaqamba kunye nokunyaniseka kunye nokunyaniseka kwemibala kwiscreen esibonisa isikrini sokubonisa.
Isishwankathelo
Imbono yokutshintsha ukukhanya kweetshipsi ze-LED ngeliso lomntu kubonisa ubudlelwane obungapheliyo kunye notshintsho lokuqaqamba kwe-led. Le jika libizwa ngokuba yijika le-gamma. Imvakalelo yeliso lomntu kwii-wavelengdwe ezahlukeneyo zombala zahlukile, kwaye izikrini eziboniswayo zineziphumo ezingcono zokubonisa. Ukuqaqamba komahluko kunye nomahluko wemibala kwesikrini somboniso kufuneka kulawulwe ngaphakathi kuluhlu olungenakuqonda, ukuze izikrini zokubonisa ezi-LED zibonisa ukungangqinelani okulungileyo.
Ukukhanya kunye nokuqaqamba kwezixhobo ezipakishwe ama-Affan okanye i-cob ekupakishwe i-cob yokukhupha i-Chips ekhutshiwe Ukuqinisekisa ukuguquguquka okuhle kwezikrini zokubonisa i-LED, inqaku malunga netekhnoloji yokulungisa i-PHOS inokusetyenziswa ukuqaqambisa ukukhanya okungaguqukiyo kunye nokuchuma kwezikrini zokubonisa ezi-LED kunye nokuphucula umgangatho.
