Ungasikhetha kanjani isibonisi sangaphandle se-LED ukuze sivumelane nezidingo zakho?

Isibonisi se- LED sangaphandle singabonakala kuyo yonke indawo okungasasimanga kithina. Ungawukhetha kanjani umkhiqizo ukuze uhambisane nezidingo zakho? Ake sabelane ngolwazi oluthile futhi sigxile kuzinto eziyisisekelo zokukhetha isibonisi se-LED:

Uhlobo 1

Ngokuya ngombala wama-LED asetshenzisiwe, izibonisi zangaphandle ze-LED zingahlukaniswa ngemibala eyinhloko eyodwa, imibala emibili eyinhloko, kanye nokuboniswa kombala okugcwele. Isibonisi se-single-primary se-LED singasetshenziswa njengesibonisi sombhalo. Iphikseli ngayinye isebenzisa i-LED enombala owodwa, ikakhulukazi ebomvu. Isibonisi se-dual-primary LED singasetshenziswa njengesibonisi sokuqhafaza. Iphikseli ngayinye inamashubhu e-LED amabili abomvu naluhlaza. Ingakwazi ukubona imibala emithathu yokubonisa okubomvu, okuluhlaza nokuphuzi; ukubonisa okugcwele kwe-LED kungasetshenziswa njengesibonisi sevidiyo, iphikseli ngayinye yakhiwa ngokubomvu, okuluhlaza okotshani nokuhlaza okwesibhakabhaka. Amaqembu amashubhu e-LED, futhi umbala wokubonisa ulungile.

Isikhala 2.Dot

Lapho ukhetha ukuboniswa kwe-LED yangaphandle, isikhala sephoyinti sesikrini sokubonisa kufanele sikhethwe ngokuya ngebanga lezithameli. I ongaphandle LED ukubonisa kwesikrini ngokuvamile has P5, P6, P8, P10, ikhasi 16 nokunye ngokuvumelana Isikhala ichashaza.

3. Isikali esimpunga

Isikali esimpunga siyinkomba ebalulekile yokukala umphumela wokubonisa wesibonisi sangaphandle se-LED. Isikali esimpunga sinqunywa inani lokuguqulwa kwe-analog-to-digital okusekelwa enye i-hardware esekelayo. Okujwayelekile kunamabhithi ayi-8, izingcezu eziyi-10 nezingu-16. Ukuguqulwa kwenombolo kufana nezinhlobo ezingama-256 zokushintsha kokukhanya, okungukuthi, amazinga angama-256 empunga.

4. Indlela yokushayela

Imodi yokushayela yesibonisi esingaphandle se-LED kufanele inqunywe ngokuya ngomphumela wokubonisa olindelekile nesabelomali. Izikrini zokubonisa ze-LED ngokuvamile ziqhutshwa yimanje engaguquki. Izindlela zokushayela zihlukaniswe ukuskena okungaguquki nokuskena okunamandla. Ngamazwi alula, ukuskena okumile ukulawula i-LED eyodwa ye-chip eyodwa yokushayela, futhi ukuskena okunamandla ukusebenzisa indlela yokuqabula iphini elilodwa le-chip yokushayela ukulawula ama-LED amaningi ukukhanyisa. I-static ukuskena ukubonisa umphumela kuhle, ukulahleka ukukhanya lincane kodwa izindleko kuqhathaniswa eliphezulu, ashukumisayo ukuskena ukubonisa umphumela kuqhathaniswa abampofu, ukulahleka ukukhanya likhulu, kodwa izindleko kungancishiswa. Ukuskena okuvamile okunamandla yi-1/2 sweep, 1/4 sweep, 1/8 sweep, and 1/16 sweep.

5.Screen ukugqama

Isibonisi esingaphandle se-LED siyindawo yokugcina engaphandle engasetshenziselwa ukubonisa konke-isimo sezulu. Ngakho-ke, imfuneko yokukhanya kwesikrini iqinile. Ngokuvamile, lapho isikrini lapho isikrini sihlala soth sibheke ngasenyakatho, ukukhanya kwesikrini akufanele kube ngaphansi kuka-4000 cd / m2; Lapho isikrini sihlala ngasenyakatho sibheke ngaseningizimu, ukukhanya kuyadingeka ukuthi kungabi ngaphansi kuka-8000 cd / m2, umphumela omuhle wokubonisa ungatholakala.
