Ngemibala egqamile nokusebenza kahle kwamandla aphezulu, izibonisi ze-LED ezinombala ogcwele zisetshenziswe kabanzi emikhakheni eminingi njengokukhangisa, imidlalo, imicimbi yezemidlalo kanye nokusabalalisa ulwazi lomphakathi. Ngokuthuthuka kobuchwepheshe, izidingo zabasebenzisi zokucaca kwesibonisi ziyakhula.
Ukuze kuhlangatshezwane nalezi zidingo, ukuthuthukisa ukucaca kwesibonisi se-LED esinemibala egcwele sekuyindaba ebalulekile embonini. Kulesi sihloko, sizohlaziya ngokujulile izindlela ezihlukahlukene zokuthuthukisa ukucaca kwezibonisi ze-LED ezinombala ogcwele ukuze sisize abafundi baqonde kangcono lesi sihloko esiyinkimbinkimbi.
I. Ukukhetha ukuphakama kwephikseli efanele
1. Incazelo yokuphakama kwephikseli
Ukuphakama kwe-Pixel yibanga eliphakathi kwezikhungo zobuhlalu be-LED obubili obuseduze, ngokuvamile obukalwa ngamamilimitha (mm). Uma ukuphakama kwephikseli kuncane, amaphuzu amaphikseli amaningi afakwa esibukweni, ngaleyo ndlela kuthuthukiswe ukucaca kwesithombe.
2. Ukuthuthukiswa kwe-Pixel Pitch
Ezimweni ezihlukene zohlelo lokusebenza, kubaluleke kakhulu ukukhetha ukuphakama kwephikseli efanele. Izindawo zasendlini zingakhetha ukuphakama kwephikseli encane (isb. P1.5 noma P2.5), kuyilapho izindawo zangaphandle zidinga ukucabangela ibanga lezithameli zokubuka futhi zikhethe ukuphakama kwephikseli enkulu (isb. P4 noma P8). Ngomklamo ophusile wephikseli, izindleko kanye nokusetshenziswa kwamandla kungalawulwa ngenkathi kuqinisekiswa ukucaca.
3. I-Pixel Density Improvement
Ukuthuthukisa ukuminyana kwephikseli kuyindlela eyodwa esebenzayo yokuthuthukisa umphumela wokubonisa. Ngokuthuthuka kobuchwepheshe, kuvela izibonisi eziningi ze-LED ezincanyana kakhulu, futhi imikhiqizo efana ne-P1.2 ne-P1.5 kancane kancane iba inkambiso emakethe. Ukuminyana kwamaphikseli aphezulu akunikezi nje kuphela izithombe ezinemininingwane eminingi, kodwa futhi kuthuthukisa ngempumelelo umuzwa obonakalayo uma ubhekwa kude.
II. Lungiselela ikhwalithi yobuhlalu besibani se-LED
1. Ukukhethwa kohlobo lobuhlalu besibani
Ukucaca kwesibonisi se-LED kuhlobene eduze nohlobo lobuhlalu be-LED obusetshenziswa. Ukukhethwa kwekhwalithi ephezulu ye-SMD (idivayisi yokukhweza ngaphezulu) ubuhlalu be-LED kungathuthukisa ngempumelelo ukucaca kwesithombe nokugcwala kombala. Ubuhlalu besibani bekhwalithi ephezulu buvamise ukuba nokukhanya okuphezulu, ukufana okukhanyayo okungcono kanye ne-engeli yokubuka ebanzi.
2. Ukulungiswa kokushisa kombala kobuhlalu besibani
Ubuhlalu besibani se-LED obuhlukile bungase bukhiqize amazinga okushisa emibala ehlukene, okuthinta umphumela wokubonisa nokucaca. Ngokulungisa izinga lokushisa lombala ukuze kuqinisekiswe ukufana kombala wesibonisi, kungathuthukisa ubuqiniso nomuzwa wokulandelana kwesithombe.
3. Ukulawulwa kokwehluleka kokukhanya kobuhlalu besibani
Ubuhlalu besibani se-LED buzoba nokubola kokukhanya ngesikhathi sokusebenzisa, okuholela ekwehleni komphumela wokubonisa. Ukugcina ukugqama nokuzinza kombala kobuhlalu besibani ngokuqapha njalo nokushintsha ubuhlalu besibani esigugayo kungathuthukisa ngempumelelo ukucaca okuphelele kwesibonisi.
III. Ukuthuthukiswa kobuchwepheshe bokushayela
1. Ukukhetha i-chip yomshayeli
I-Driver chip iyingxenye ebalulekile yokulawula isibonisi sesithombe sesibonisi se-LED. I-chip yomshayeli esebenza kahle kakhulu ingalawula ngokunembe kakhudlwana ukukhanya nombala wobuhlalu besibani ngasinye se-LED, ngaleyo ndlela ithuthukise ukucaca okuphelele. Ukukhetha i-chip yomshayeli enezinga eliphezulu lokuvuselela kanye nezinga lokuhluleka eliphansi kungathuthukisa ngempumelelo ukucaca kwesithombe esiguqukayo futhi kunciphise into elokozayo.
2. Ukuthuthukiswa kwezinga elimpunga
Ileveli empunga yinto eyinhloko ethinta izinga lemininingwane yesikrini esibonisiwe. Ileveli ephezulu ye-grayscale yesibonisi se-LED ingethula imibala ecebile nezithombe ezinemininingwane eyengeziwe. Ngokuvamile, i-8-bit grayscale (amazinga angu-256) isingakwazi kakade ukuhlangabezana nezidingo zezinhlelo zokusebenza eziningi, kodwa ezinhlelweni zokusebenza ezisezingeni eliphezulu, ungacabangela isibonisi se-grayscale esingu-16-bit ukuze uthuthukise ukucaca.
3. Vuselela Ukuthuthukiswa Kwezinga
Izinga lokuvuselela lithinta ngokuqondile ukucaca nokushelela kwesithombe esiguqukayo. Izinga lokuvuselela eliphezulu (elifana no-3840Hz nangaphezulu) lesibonisi se-LED lingagcina ukucaca esithombeni esinyakaza ngokushesha, ukugwema isipoki nokufiphaza. Ikakhulukazi emicimbini yezemidlalo namakhonsathi, izinga eliphezulu lokuvuselela libaluleke kakhulu.
IV.Idizayini Yemvelo kanye Nesakhiwo Sokubonisa
1. Ibanga elifanele lokubuka
Ukucaca akuhlobene kuphela nezinkomba zobuchwepheshe zesibonisi ngokwazo, kodwa futhi kuhlobene eduze nebanga lokubuka. Idizayini enengqondo yobude bokufaka nebanga lokubuka lesibonisi lingathola umuzwa ongcono kakhulu wokubuka emaqenjini ahlukene ezithameli.
2. Ukukhanya kwemvelo okufanele
Ukucaca kwesibonisi nakho kuthintwa ukukhanya kwe-ambient. Ukukhanya okuzungezile okunamandla kakhulu noma okubuthakathaka kakhulu kuzothinta umphumela wokubuka. Ngokuklama kwemvelo okunengqondo, ukuqinisekisa ukuthi isibonisi esisesimweni esingcono kakhulu sokukhanya, singathuthukisa kakhulu ukucaca nolwazi lokubuka kwezithameli.
3. Ukugcinwa Nokuhlanza Isibonisi
Ukunakekelwa okuvamile nokuhlanza isibonisi ukuze kukhishwe uthuli namabala kungathuthukisa ngempumelelo izinga laso lokudlulisa ukukhanya nokucaca. Ukunakekela akubandakanyi ukuhlanza ngokomzimba kuphela, kodwa futhi nokuhlola okuvamile kokuxhumeka kukagesi nokusebenza kwesofthiwe ukuze kuqinisekiswe ukusebenza kahle kwesibonisi.
