Indlela yokukhetha umboniso we-LED ongaphandle ukuze uhambelane neemfuno zakho?

Umboniso we- LED ongaphandle unokubonakala kuyo yonke indawo engasothusi kuthi. Ungayikhetha njani imveliso ehambelana neemfuno zakho? Masibe ngamava kwaye sijolise kwizinto ezisisiseko zokukhetha umboniso we-LED:

1 Uhlobo

Kuxhomekeke kumbala wee-LEDs ezisetyenzisiweyo, iziboniso zangaphandle ze-LED zinokwahlulwa zibe yimibala yokuqala, imibala emibini ephambili kunye nemibala epheleleyo. Umboniso we-LED oyintloko ungasetyenziselwa ukubonisa isicatshulwa. I-pixel nganye isebenzisa i-LED enemibala enye, ubukhulu becala ibomvu. Umboniso ophambili we-LED unokusetyenziswa njengomboniso wegraphic. I-pixel nganye inezinto ezimbini ezibomvu neziluhlaza iityhubhu ze-LED. Inokuqonda imibala emithathu yomboniso obomvu, oluhlaza kunye notyheli; Umbala opheleleyo we-LED unokusetyenziswa njengomboniso wevidiyo, ipikseli nganye yenziwe ngombala obomvu, oluhlaza kunye noluhlaza okwesibhakabhaka. Amaqela e-tube ye-LED, kwaye umbala wokubonisa ulungile.

Isithuba 2.Dot

Xa ukhetha umboniso we-LED ongaphandle, ukushiyana kwenqaku lescreen sokubonisa kufuneka kukhethwe ngokomgama wabaphulaphuli. I ngaphandle LED isikrini ngokubanzi P5, P6, P8, P10, i16 njalo ngokungqinelana dot izithuba.

3. Isreyini esingwevu

Isilinganisi esingwevu sisalathiso esibalulekileyo sokulinganisa umphumo womboniso we-LED yangaphandle. Isilinganisi esingwevu simiselwa linani lokuguqulwa kwe-analog-to-digital exhaswa yenye i-hardware exhasayo. Eyona ndawo iphambili inee-8 bits, 10 bits kunye ne-16 bits. Ukuguqulwa kwenani kungqinelana neentlobo ezingama-256 zokutshintsha kokuqaqamba, oko kukuthi, amanqanaba angama-256 engwevu.

4. Indlela yokuqhuba

Imowudi yokuqhuba yokubonisa ngaphandle kwe-LED kufuneka igqitywe ngokubhekisele kwisiphumo esilindelweyo sokubonisa kunye nohlahlo-lwabiwo mali. Izikrini zokubonisa ze-LED ziqhutywa ngokubanzi ngoku. Iindlela zokuqhuba zohlulahlulwe zaba sisimo sokuskena esihleliyo kunye nokuskena okunamandla. Ngamagama alula, ukuskena okungashukumiyo kukulawula i-chip enye ye-chip yokuqhuba, kwaye ukuskena okunamandla kukusebenzisa indlela ehlaziyayo yepini enye ye-chip yokuqhuba ukulawula ii-LED ezininzi ukukhanyisa. Isiphumo sokubonisa ukuskena okuhle asinto intle, ilahleko yokukhanya incinci kodwa iindleko ziphezulu kakhulu, isiphumo sokubonisa amandla sokuskena sihlwempuzekile, ilahleko yokukhanya inkulu, kodwa iindleko zinokuncitshiswa. Izikena eziqhelekileyo ezinamandla zi-1/2 ukutshayela, 1/4 ukutshayela, 1/8 ukutshayela, kunye no-1/16 ukutshayela.

Ukuqaqamba 5.Screen

Umboniso we-LED ongaphandle sisiphelo esingaphandle esinokusetyenziselwa umboniso wemozulu yonke. Ke ngoko, imfuno yokukhanya kwesikrini ingqongqo. Ngokubanzi, xa isikrini xa isikrini sihlala soth ukujongana ngasentla, ukukhanya kwesikrini akufuneki kube ngaphantsi kwe-4000 cd / m2; Xa isikrini sihlala emantla sijongise emazantsi, ukukhanya kuyadingeka ukuba kungabikho ngaphantsi kwe-8000 cd / m2, isiphumo esingcono sokubonisa sinokufezekiswa.
