Uchonga njani uMgangatho weZiboniso ze-LED: Isikhokelo esiBanzi

Kule mihla yedijithali, Umboniso we-LEDibe yinxalenye ebalulekileyo yobomi bethu, ukusuka kwiibhodi zentengiso ukuya kwiinkqubo zokuzonwabisa zasekhaya. Noko ke, asingabo bonkeUmboniso we-LEDzidalwe zilingana. Ukwazi indlela yokuchonga umgangatho wezi zibonisi kubalulekile ukwenza isigqibo sokuthenga unolwazi. Kweli nqaku, siza kuphonononga iimpawu ezisisiseko ezisithoba ezichaza umgangatho weUmboniso we-LEDngokubanzi, ilandelwa ziimpawu ezongezelelweyo ezikhethekileyo kwi-fine-pitch LED displays.

 

1. Ukucaba

 

Inkalo yokuqala ekufuneka iqwalaselwe xa kuvavanywa iUmboniso we-LEDkukucaba kwayo.Isikrini se-LED esikumgangatho ophezulu kufuneka ibe nomphezulu othe tyaba ngokugqibeleleyo. Nakuphi na ukuphazamiseka okanye ukungalingani kuya kubangela umfanekiso ogqwethekileyo kunye namava okujonga kakubi ngokubanzi. Ukuvavanya ukuthambeka, unokujonga ngokubonakalayo isikrini ukusuka kwii-engile ezahlukeneyo kunye nemigama. Isikrini esisicaba siya kubonelela ngomfanekiso ohambelanayo ngaphandle kwamaqhuma abonakalayo okanye idiphu.

2. Ukukhanya kunye ne-angle yokujonga

Ukukhanya yenye into ephambili ekumiseleni umgangatho wesiboniso se-LED. EntleIsikrini se-LEDkufuneka ibe nokukhanya okuphezulu kokujonga okucacileyo kwiimeko ezahlukeneyo zokukhanyisa. Ii-engile zokujonga nazo zibalulekile; Umboniso olungileyo kufuneka ugcine umbala ukuchaneka kunye nokuqaqamba nokuba ujongwe ecaleni. Ukuvavanya oku, yima kwii-engile ezahlukeneyo kwaye ubone ukuba umfanekiso uhlala ucacile kwaye ucacile.

3. Isiphumo esimhlophe sokulinganisela

 

Ibhalansi emhlophe ibalulekile kumelo oluchanekileyo lombala. EntleUmboniso we-LEDkufuneka ibonakale imhlophe qwa, ngaphandle kwe-tint. Ukuvavanya oku, bonisa umfanekiso omhlophe ococekileyo kwaye ujonge ukuba ubonakala umhlophe okanye unombala omthubi, oblowu, okanye oluhlaza. Isikrini esilinganiswe kakuhle siya kubonisa umhlophe ongathathi hlangothi, oqinisekisa ukuba yonke imibala imelwe ngokuchanekileyo.

4. Ukubuyiselwa kombala

 

Ukuveliswa kombala kubhekiselele kwisakhono seUmboniso we-LEDukuvelisa ngokuthembekileyo imibala. Isikrini somgangatho ophezulu kufuneka sibonise imibala ecacileyo, efana nobomi. Ukuvavanya oku, thelekisa imibala ekwisikrini kwizinto zokwenyani okanye itshathi yereferensi yombala. Ukuba imibala ibonakala ibuthuntu okanye igqwethekile, umboniso mhlawumbi awukho kumgangatho ophezulu.

5. Mosaic okanye indawo efileyo

 

Esinye sezibonakaliso ezibalulekileyo zeUmboniso we-LEDumgangatho bubukho be-mosaic okanye ipixels ezifileyo. Ezi ziindawo zesikrini ezingakhanyiyo okanye ezibonisa imibala engachanekanga. Umgangatho olungileyoUmboniso we-LED akufuneki ukuba neepixels ezifileyo okanye iziphumo ze-mosaic. Ukujonga oku, bonisa umfanekiso oqinileyo wombala kwaye ubone ukuba kukho ukungahambelani. Ukuba ufumana naziphi na iipixels ezifileyo, oko kunokubonisa umgangatho ombi wesikrini.

6. Iibhloko zemibala

Ukuvalwa kombala kuxa imibala ibonakala kwiibhloko ezahlukileyo endaweni yokudibanisa kakuhle. Umgangatho ophezulu Umboniso we-LED kufuneka ibe notshintsho olungenamthungo phakathi kwemibala. Ukuvavanya ukubhloka kombala, bonisa umfanekiso wegradient kwaye ujonge ukuba imibala ihlangana kakuhle okanye kukho imigca okanye iibhloko ezibonakalayo. Isiboniso esikumgangatho ophezulu siya kubonisa iigradient ezigudileyo ngaphandle kotshintsho olukhawulezileyo.

7. Ukuhambelana kweWavelength

Ubude bokukhanya obukhutshwa yi-Umboniso we-LEDimisela ubunyulu kunye nokuhambelana kombala. Umgangatho olungileyo Umboniso we-LEDkufuneka ikhuphe ukukhanya kobude obuthile obuhambelana nombala osulungekileyo. Ukuvavanya oku, ungasebenzisa i-colorimeter okanye i-spectrometer ukulinganisa i-wavelengths ekhutshwe sisiboniso. Ubude obungaguqukiyo bubonisa isikrini somgangatho ophezulu.

8. Ukusetyenziswa kwamandla kwi-square meter nganye

Ukusetyenziswa kwamandla yinto ebalulekileyo ekufuneka iqwalaselwe, ngakumbi kwiziboniso ezinkulu. Umboniso we-LED osemgangathweni kufuneka ube nokusetyenziswa kwamandla aphantsi kwimitha yesikwere ngelixa ubonelela ngokukhanya okuphezulu kunye nokusebenza. Oku akunciphisi iindleko zokusebenza kuphela kodwa kunciphisa impembelelo yokusingqongileyo. Jonga imilinganiselo yomboniso ukuthelekisa amazinga okusetyenziswa kwamandla.

9. Ireyithi yokuhlaziya

 

Umyinge wohlaziyo lweUmboniso we-LED ibalulekile kwintshukumo egudileyo kunye nokuncitshiswa kokuqhwanyaza. Izinga eliphezulu lokuhlaziya likhokelela kumfanekiso ogudileyo, ngakumbi ngomxholo ohamba ngokukhawuleza. UmgangathoUmboniso we-LED kufuneka ibenereyithi yokuhlaziya ubuncinci i-60Hz. Ukuvavanya oku, jonga ividiyo ehamba ngokukhawuleza okanye oopopayi kwisikrini kwaye ujonge nakuphi na ukufiphala okanye ukuqhwanyaza.

10. Ukuthelekisa

 

Umlinganiselo wothelekiso ulinganisa umahluko phakathi kweendawo ezimnyama nezikhaphukhaphu zomfanekiso. Umgangatho ophezuluUmboniso we-LED kufuneka ibenomlinganiselo ophezulu wokuchasana ukufikelela kwabamnyama nzulu kunye nabamhlophe abaqaqambileyo. Ukuvavanya oku, bonisa umboniso oqulethe zombini izinto ezimnyama nezikhanyayo kwaye ujonge ubunzulu bomnyama kunye nokuqaqamba kwabamhlophe. Umlinganiselo omhle wokuchasana uphucula amava okubukela ngokubanzi.

11. Ubushushu boMbala

Ubushushu bombala bubhekisa kubushushu okanye ukubanda kokukhanya okukhutshwa ngumboniso. UmgangathoUmboniso we-LEDkufuneka ibenobushushu obunokulungiswa kombala onokuthi ulungelelaniswe iimeko zokujonga ezahlukeneyo. Ukuvavanya oku, hlengahlengisa isethingi yobushushu bombala kwaye ujonge ukuba umfanekiso utshintsha njani. Umboniso womgangatho uya kuvumela uluhlu lwamaqondo okushisa ngaphandle kokunciphisa umgangatho womfanekiso.

12.Umboniso wangaphakathi wesandi esincinci: ukukhanya okuphantsi, i-grayscale ephezulu

 

Kubaimiboniso ye-LED yangaphakathi, kukho izinto ezimbini ezingakumbi ekufuneka ziqwalaselwe: ukukhanya okuphantsi kunye negreyscale ephezulu. Ezi ziboniso ziyilelwe ukujongwa ngokusondeleyo, ngoko ke ukukhanya kufuneka kube phantsi ukuthintela ukudinwa kwamehlo. Nangona kunjalo, kufuneka bagcine i-grayscale ephezulu ukuqinisekisa i-gradients ezigudileyo kunye nokutshintsha kombala. Ukuvavanya oku, jonga umboniso kufutshane kwaye ujonge naziphi na iimpawu zebhendi okanye ukungafani kombala.

Ukumisela umgangatho weUmboniso we-LEDifuna uphononongo olucokisekileyo lweempawu ezahlukeneyo, ukusuka ekukhanyeni kunye nokuqaqamba ukuya kwimveliso yombala kunye nokusetyenziswa kwamandla. Ngokuqonda le miba iphambili, unokwenza isigqibo esinolwazi xa uthenga iUmboniso we-LEDkusetyenziso lomntu okanye lobungcali. Nokuba ujonge umboniso wentengiso, ukuzonwabisa, okanye nayiphi na enye injongo, ukugcina ezi zinto engqondweni kuya kukunceda ukhethe isikrini se-LED esikumgangatho ophezulu esihlangabezana neemfuno zakho.
