1. Ukucaba

Umphezulu othe tyaba wesikrini sokubonisa kufuneka ube ngaphakathi ±1m ukuqinisekisa ukuba umfanekiso obonisiweyo awugqwethwanga. Amaqhuma asekuhlaleni okanye iindawo ezisemva ziya kubangela amabala angaboniyo kwi-engile yokujonga kwesikrini sokubonisa. Umgangatho we-flatness umiselwa ikakhulu yinkqubo yemveliso.

2.Ukukhanya kunye ne-angle yokujonga

Ukukhanya kwesikrini sangaphakathi esinombala ogcweleyo kufuneka sibe ngaphezulu kwe-800cd/m2, kwaye ukuqaqamba kwesikrini esingaphandle esinombala ogcweleyo kufuneka sibe ngaphezulu kwe-1500cd/m2 ukuqinisekisa ukusebenza okuqhelekileyo kwesiboniso. Ngaphandle koko, umfanekiso obonisiweyo awuyi kucaca kuba ukukhanya kuphantsi kakhulu.

Ukukhanya kunqunywe ngokukodwa kumgangatho we-tube ye-LED. Ubungakanani be-engile yokujonga bumisela ngokuthe ngqo ubungakanani babaphulaphuli besikrini sokubonisa, ngoko ke inkulu ingcono. Ubungakanani be-angle yokujonga ubukhulu becala bunqunywe yindlela yokupakisha yokufa.

3. Isiphumo esimhlophe sokulinganisela

Isiphumo esimhlophe sokulinganisela sisona silathisi esibalulekileyo sesikrini sokubonisa. Ngokubhekiselele kwithiyori yombala, umhlophe ococekileyo uya kuboniswa xa umlinganiselo wemibala emithathu ephambili ebomvu, eluhlaza kunye nohlaza okwesibhakabhaka ngu-3: 6: 1. Ukuba umlinganiselo wangempela uphambukiswa kancinci, kuya kwenzeka ukuphambuka kwebhalansi emhlophe.

Ngokubanzi, Nika ingqalelo ukuba umbala omhlophe bluish okanye tyheli-luhlaza. Umgangatho webhalansi emhlophe unqunywe ngokukodwa yinkqubo yokulawula isikrini sokubonisa. I-tube core nayo ichaphazela ukuveliswa kombala.

4. Ukubuyiselwa kombala

Ukubuyiselwa kombala kubhekisa kumandla omboniso wokubuyisela imibala. Oko kukuthi, umbala oboniswe kwisiboniso kufuneka uhambelane kakhulu nombala womthombo wokudlala, ukuze uqinisekise ubunyani bomfanekiso.

5. Ingaba ikhona imosaic okanye indawo efileyo?

I-Mosaic ibhekisa kwizikwere ezincinci ezivela kwiscreen sokubonisa ezihlala ziqaqambile okanye zimnyama. Yinto eyenzeka kwimodyuli necrosis. Isizathu esona sizathu kukuba umgangatho wesidibaniso esisetyenziswe kwisikrini sokubonisa awulungile ngokwaneleyo. Inani lamanqaku aqaqambileyo okanye aqhelekileyo amnyama kunye namanqaku afileyo anqunywe ngokukodwa ngumgangatho we-tube core.

6. Ingaba ikhona ibhloko yombala?

Ibhloko yombala ibhekiselele kumahluko ombala ocacileyo phakathi kweemodyuli ezikufutshane, kwaye utshintsho lombala lusekwe kwimodyuli. Isiganeko sebhlokhi yombala sibangelwa ikakhulu yinkqubo yokulawula engalunganga, inqanaba eliphantsi legrey kunye ne-low scanning frequency.
