Kako nastane osvetlitev ozadja

Proizvodni postopek osvetlitve za ozadje vključuje predvsem naslednje korake:

Chip preparation: The core of LED backlight is the LED chip, which includes steps such as crystal growth, cutting, cleaning, and sapphire substrate preparation. Crystal growth is the most critical step, which involves controlling the crystallization process of materials under specific conditions to prepare crystals with specific structures and physical properties. Cutting is to cut the grown crystal into small pieces, Med čiščenjem in safirnim pripravo substrata naj bi zagotovili čistost površine in ravnost čipa

Packaging technology: After the preparation of LED chips is completed, they need to be packaged to protect the chips and facilitate subsequent assembly and application. Packaging technologies include conductive adhesive packaging, adhesive free packaging, and ball grid packaging. Conductive adhesive packaging is the most common method, which involves placing the chip on the packaging base and using conductive adhesive for fixation in električna povezava

Coating of luminescent layer: The luminescent layer is an important component of LED backlight, which determines the luminous effect and color performance of the LED. Luminescent layer coating is the process of coating a luminescent powder solution onto an LED chip, including steps such as solution preparation, coating, and curing. The preparation of the solution requires precise control of the type and Koncentracija luminescentnega prahu in postopek prevleke zahteva nadzor nad enakomernostjo in debelino prevleke

Sklop osvetlitve ozadja: V določeni razporeditvi na bazi sestavite več LED čipov, da izboljšate svetlobno učinkovitost in enakomernost . Med postopkom sestavljanja je treba uporabiti materiale, kot so lahke vodilne plošče, difuzijski filmi in odsevni filmi

Varjenje in testiranje: LED privarite na ploščo PCB in izvajajte testiranje, da se zagotovi dobre fotoelektrične parametre in svetlobno enakomernost . Med postopkom testiranja je treba preveriti svetlost, enakomernost in stabilnost vira ozadja vira

Embalaža: embalaža in shranjevanje končnih izdelkov v skladu z zahtevami, priprava na prodajo
