Isiboniso se-mini LED ngqo sisebenza kakuhle kakhulu kune-LCD

2024-10-09

I-LED encinci uphuhliso ukuza kuthi ga ngoku, ngenxa yokukhula kobuchwepheshe, ukukhanya kwayo okuphezulu, umahluko ophezulu, umbala ophezulu kunye nezinye iimpawu ziye zaqatshelwa kancinci kancinci ngabathengi. Nangona kunjalo, kube nzima ukuphelisa ingcamango yokubonisa ngokuthe ngqo "kwabathengi bamandla" be-LED.

Ngoko ke, iphi i-stereotype ye I-Mini LED's ukusetyenziswa kwamandla aphezulu kuvela phi?

Kwelinye icala, iitships ze-LED zemveli zinkulu kwaye azisebenzi kakuhle. Isikrini se-LED esiqhelekileyo kubomi bemihla ngemihla sisesiboniso se-SMD LED samaqhekeza amakhulu ee-particle. Olu hlobo lwesiboniso se-SMD lwenziwe ngephakheji elungileyo yee-light beads, i-light chip esetyenziswa kwii-lamp beads inkulu kakhulu kune-Mini LED chip, kwaye ukusebenza kakuhle kokukhanya kunye nokusebenza kakuhle kokusasaza ubushushu kuphantsi kakhulu.

I-Mini LED flip chip inokukhanya okuphezulu nokusebenza kakuhle okukhanyayo kune-chip enkulu esetyenziswa kwi-SMD yendabuko (1010/1212/1515, njl.njl.); Ke ngoko, phantsi kweemeko ezifanayo, I-LED encinci Ukusetyenziswa kwamandla e-flip chip nako kuphantsi.

Kwelinye icala, ii-LED zangaphandle zishiya ingcamango eqhelekileyo. Ukuboniswa ngqo kwe-LED kwintsimi yokuboniswa kwangaphakathi akukadluli xesha lide, kwaye ingqiqo yendabuko yokuboniswa ngqo kwe-LED ixhaphake kakhulu ngaphandle. Ukuboniswa ngokubanzi kwangaphakathi, nokuba yi-LCD okanye yi- I-LED, ukukhanya kwi-200-400nit kwanele, kodwa ngenxa yeemfuno zorhwebo, ukukhanya okufunekayo yi-LED yangaphandle kuphindwe kaninzi kunokwangaphakathi, kufikelela kwi-8000 okanye i-10000nit, ukusetyenziswa kwamandla ngokwemvelo akufani. Kwaye indawo yesikrini sasekhaya ikwaphindwe kalikhulu kunokwesikrini sangaphakathi, ngoko ke i-LED ishiya ingcamango yokuba kungekuphela nje ubushushu obunzima, kodwa nokusetyenziswa kwamandla kwesikrini sonke kuphezulu kakhulu.

Kutheni i-crystal engamanzi idla amandla angaphezu kwe-impression?

Ngenxa yokuba I-LCD Ayikwazi ukucima umaleko we-backlight. Umboniso we-liquid crystal ufezekiswa ziinkqubo ezimbini ezahlukeneyo: i-backlight inoxanduva lokubonelela ngokukhanya, kwaye iimolekyuli ze-liquid crystal zilawula umbala, ukukhanya kunye notshintsho olumnyama ngokujika. Ke ngoko, logama nje i-LCD ivuliwe, nokuba yeyiphi na isikrini eboniswayo, nokuba sisikrini esimnyama, umaleko we-backlight ubusoloko ukhanya kwaye uzinzile, kwaye awunakulungiswa okanye uvalwe ngokukhululekileyo.

Isibonisi se-LED ngqo sizikhanyisa ngokwaso yi-chip ye-LED, ukukhanya nombala ziqhutywa ngqo yi-current kunye ne-voltage. I-LED itshiphu ekufuneka ifezekiswe, iiphikseli ezimnyama ukukhanya okuphantsi, ukusetyenziswa kwamandla okuphantsi, iiphikseli ezimnyama azikhuphi ukukhanya, ukusetyenziswa kwamandla akusebenzi.
