Eminyakeni yamuva nje, imakethe yokubonisa i-elekthronikhi ye-LED ibithandwa kakhulu, ishayela yonke imboni yokubonisa i-LED esigabeni sokukhula ngokushesha.Ngokungeziwe kuzikrini zokukhangisa, izikrini zobuciko obudlalwayo, nezikrini zokuqondisa kwethrafikhi ezisetshenziswa kakhulu ngaphandle, izibonisi ze-LED zasendlini nazo ziyimakethe enamandla amakhulu, okuhlanganisa izikrini ezinkulu zokugada zasendlini nezindonga zamakhethini zikagesi zasendlini.Kodwa ngokombono wezobuchwepheshe, eqinisweni, eminyakeni eyi-10 edlule noma ngaphezulu, izikrini ze-LED ezethulwa abakhiqizi abaningi azizange zishintshe kakhulu ekwakhiweni kwesistimu eyisisekelo, kodwa ziye zathuthukiswa ngezinga elithile ngokuhambisana nezinkomba ezithile zobuchwepheshe. .Nokulungiswa.

Ngasikhathi sinye, ukuthandwa nokukhuthazwa kwemikhiqizo esebenza kahle kakhulu kubambezeleka, yize eminyakeni embalwa edlule, bekuvele kunemikhiqizo ekhombisayo ye-IC yomshayeli enomsebenzi we-PWM (Pulse Width Modulation) emakethe, futhi abahlanganyeli bemakethe sebenayo. futhi wavumelana nomsebenzi we-PWM.Inezinzuzo zezinga eliphezulu lokuvuselela kanye namandla angashintshi.Kodwa-ke, ngenxa yenani nezinye izici, isabelo semakethe sama-IC driver wokubonisa asebenza kahle alikabi phezulu.Amamodeli ayisisekelo asetshenziswa kakhulu emakethe (njenge-Macroblock 5024/ 26 njll.), imikhiqizo ephezulu isetshenziswa kakhulu kwezinye izimakethe eziqashisayo zesikrini se-LED ezinaka kakhulu ikhwalithi.

Kodwa-ke, ngokuthuthuka okusheshayo kwemakethe yokubonisa i-Shenzhen LED, abasebenzisi abaningi ngokwengeziwe sebeqalile ukubeka phambili uchungechunge lwezidingo eziyinkimbinkimbi zezikrini ze-LED ezivela emiphumeleni yokubuka, izindlela zokudlulisa, izindlela zokubonisa, nezindlela zokudlala.Lokhu futhi kwenza ukuthi imikhiqizo ye-LED Screen ibhekane nethuba elisha lokuqamba izinto ezintsha zobuchwepheshe, futhi njengoba “ubuchopho” bohlelo oluboniswayo lwe-IC driver IC izodlala indima ebalulekile.

Ukudluliswa kwedatha phakathi kwesikrini se-LED kanye ne-motherboard ngokuvamile kusebenzisa i-serial data transmission (SPI), bese idlulisela ngokuhambisana idatha yokubonisa kanye nedatha yokulawula ngobuchwepheshe bokuphindaphinda kwephakethe lesignali, kodwa uma izinga lokuvuselela nokulungiswa kuthuthukiswa, Kulula ukubangela ibhodlela ekudluliselweni kwedatha, okuholela ekungazinzini kwesistimu.Ngaphezu kwalokho, lapho indawo yesikrini yesikrini se-LED inkulu, ulayini wokulawula uvamise ukuba mude kakhulu, okungase kube lula ukuphazanyiswa yi-electromagnetic, okuthinta ikhwalithi yesiginali yokudlulisela.

Nakuba abanye abakhiqizi bethule imidiya emisha yokudlulisela eminyakeni yamuva, indlela yokuhlinzeka abasebenzisi ngokusebenza okuhle kakhulu kanye nezixazululo zomkhiqizo ezingabizi kuyinkinga ebalulekile ekhungethe imboni.Kuze kube manje, abanye abakhiqizi baphakamise ukuthi indlela yokudlulisa idatha yezikrini zokubonisa ze-LED idinga ngokuphuthumayo ukuthi iqale kusukela ezingeni eliphansi kakhulu lobuchwepheshe futhi ithole isisombululo esisha.

Kuyaphawuleka ukuthi ukusungulwa okusha kwezobuchwepheshe kwezikrini ze-LED kuhilele zonke izici zochungechunge lwezimboni, okuhlanganisa ukuthuthukiswa kwenqubo yokukhiqiza i-IC yomshayeli, i-hardware of control system, ukuthuthukiswa okuhlakaniphile kwesofthiwe yokulawula, njll. Lezi zinqubo ezintsha zobuchwepheshe zidinga ukuklama kwe-IC. abakhiqizi, lawula Abathuthukisi besistimu, abakhiqizi bephaneli, ngisho nabasebenzisi bokugcina bahlanganiswe ngokuseduze ukuze baphule "i-deadlock" yezinhlelo zokusebenza zemboni.Ikakhulukazi ekuthuthukisweni kwezinhlelo zokulawula, indlela yokubambisana kangcono nezinkampani zokuklama ze-IC ukuze kuthuthukiswe ukusebenza kwesistimu yezikrini ze-LED kanye nezinga elihlakaniphile lesofthiwe yokulawula yinto ebaluleke kakhulu.
