Yintoni umGaqo wokuSebenza woMboniso we-LED?

Umboniso we-LED sisixhobo esibalulekileyo sombane esisetyenziswa kakhulu ngamaxesha ahlukeneyo. Ukubunjwa kwayo, iimodyuli ezisebenzayo, kunye nomgaqo wokusebenza zibaluleke kakhulu ekuqondeni ukusebenza kwayo kunye nokusetyenziswa kwayo.

1. Ukuqulunqwa komboniso we-LED

Ukuqulunqwa komboniso we-LED

I-LED (i-Light Emitting Diode) sisixhobo se-semiconductor esiguqula amandla ombane kumandla okukhanya ngokusebenzisa iteknoloji ye-electroluminescence. Umboniso we-LED uqulunqwe ngeepikseli ezininzi, kwaye ipixel nganye iqulethe ukukhanya kwe-LED kunye ne-chip yomqhubi. Iindidi ezahlukeneyo zokubonisa i-LED zinokudityaniswa ngokweemfuno zokwenza izikrini zokubonisa ezinobukhulu obahlukeneyo, izisombululo, ubunzulu bombala, kunye nokukhanya.

2. Iimodyuli ezisebenzayo zomboniso we-LED

Imodyuli yolawulo: Imodyuli yolawulo yenye yezona ndawo zisisiseko zomboniso we-LED. Ifumana isiginali yegalelo evela kwihlabathi langaphandle kwaye iyiguqule ibe yile yangoku kunye nombane ofunekayo ukuqaqamba kwepixel nombala.

Imodyuli yomqhubi: Imodyuli yomqhubi yinxalenye ebalulekileyo yomboniso we-LED, olawula ukukhanya kunye nombala wepikseli nganye. Ngokuqhelekileyo, ipixel nganye iqhagamshelwe kwitshiphu yomqhubi. I-chip yomqhubi ifumana idatha ekhutshwe kwimodyuli yokulawula ukulawula ukukhanya kunye nombala we-LED.

 umgaqo wokusebenza

Imodyuli yokubonisa: Imodyuli yokubonisa ineepikseli ezininzi, kwaye ipikseli nganye iqulethe ukukhanya kwe-LED kunye ne-chip yomqhubi. Umsebenzi ophambili wemodyuli yokubonisa kukuguqula isignali yegalelo ibe ngumfanekiso obonakalayo.

Imodyuli yaMandla: Umboniso we-LED udinga unikezelo lwamandla oluzinzileyo lwe-DC ukuze lusebenze ngokufanelekileyo, ngoko ke imodyuli yamandla iyimfuneko. Inoxanduva lokubonelela ngamandla ombane afunekayo kunye nokuqinisekisa umbane okhuselekileyo nothembekileyo ophumayo kunye nokhoyo.

3. Inkqubo yokulawula

Inkqubo yokulawula

Inkqubo yokulawula i-LED ihlukaniswe ibe yi-synchronous kunye ne-asynchronous ezimbini. Inkqubo yokulawula i-synchronous kunye nomxholo wekhompyutheni yekhompyutheni iboniswa ngokuhambelanayo, ekufuneka ihlaziywe ngexesha langempela kwaye ixhunywe kwikhompyutheni yonke ixesha. Inkqubo yokulawula i-asynchronous igcina idatha yokubonisa kwinkqubo kwangaphambili, ngaphandle kokuchaphazeleka kwikhompyutheni, kwaye inokulawulwa ngeendlela ezahlukeneyo.

4. umgaqo wokusebenza

 umgaqo wokusebenza 2

Umgaqo wokusebenza wokuboniswa kwe-LED usekelwe kwi-teknoloji ye-LED. Xa yangoku idlula kwi-LED, inikwa amandla kwaye ikhuphe ukukhanya. Umbala we-LED uxhomekeke kwizinto zayo ze-semiconductor. Kumboniso we-LED, imodyuli yokulawula ifumana izibonakaliso zokungenisa kwizixhobo zangaphandle kwaye iguqule ibe yangoku kunye ne-voltage efunekayo ekukhanyeni kunye nombala weepikseli. Imodyuli yokuqhuba ifumana idatha edluliselwe kwimodyuli yokulawula ukulawula ukukhanya kunye nombala wepikseli nganye. Imodyuli yokubonisa yenziwe ngeepikseli ezininzi, ezinokubonisa ulwazi oluninzi oluntsonkothileyo olubonakalayo.

Ngamafutshane, ukuqonda ukubunjwa, iimodyuli ezisebenzayo, kunye nemigaqo yokusebenza yezikrini zokubonisa i-LED kubaluleke kakhulu ekuqondeni ukusebenza kwayo kunye nokusetyenziswa kwayo. Ngokuqhubela phambili okuqhubekayo kobuchwepheshe, izikrini zokubonisa i-LED ziba sisixhobo esiqhelekileyo sokubonisa.
