● Kho qhov ci ci. Siab ci ntsa iab thiab muag muag zoo nkauj ntxim nyiam nyiam cov neeg lub qhov muag.

FAQ

COB thiab GOB yog dab tsi?

Ans:COB txhais tau tias Chip on Board. Nws yog ib txoj hauv kev encapsulation rau encapsulate coj chips ntawm PCB ncaj qha. Qhov saum npoo yog ntse zoo li cov teeb coj teeb yog gluing hauv PCBs. Tsis muaj ob txhais ceg liab qab. Kev sib sau ua ke ntawm COB boards txawv nrog cov tsoos SMD boards, uas xav tau cov tshuab tshwj xeeb thiab cov cuab yeej hlau nplaum.

GOB yog lub npe luv ntawm Glue on board. Lwm lo lus yog LOB (lamination ntawm lub nkoj). Nws yog ib tug technology ntawm gluing rau saum npoo ntawm SMD modules.

Dab tsi yog LED txee?

Ans:Txee, tseem hu ua LED npo thav duab, yog cov khoom siv ntawm lub vijtsam LED. Raws li cov khoom sib xyaw ua ke, qhov screen tag nrho cov cheeb tsam saum npoo yog npog. Nyob ntawm seb hom LED screen koj xaiv rau nruab, cov khoom no txawv qhov loj, cov khoom siv, thiab kev kho kom haum.

Qhov loj ntawm LED modules yog dab tsi?

Ans:Lub pixelization ntawm cov modules txiav txim qhov loj ntawm LED modules los yog LED boards feem ntau. Piv txwv li, raws li pixel suab, ntau qhov ntau thiab tsawg yog 320x160mm lossis 160x160mm module loj rau ntau pixels 5mm yog siv. Yog li, lub module qhov loj yog 256x128mm lossis 128x128mm rau ntau 4mm pixels.

Xim distortion yog dab tsi?

Ans:Chromatic aberration (CA), tseem hu ua chromatic distortion los yog spherochromatism hauv optics, yog thaum lub lens tsis ua kom pom tseeb txhua xim rau tib lub ntsiab lus. Chromatic aberration tshwm raws li xim "fringes" raws li daim duab ciam teb uas paub qhov tsaus ntuj thiab kaj.
