Optical Bonding Tiag tiag yog dab tsi
Tus qauv tsim ntawm Standard LCD Screen
Ib qho khoom lag luam raug suav nrog cov iav npog, qhov sib txawv ntawm huab cua, kov txheej, thiab lub vaj huam sib luag LCD. Lub teeb bounces ntawm txhua huab cua - iav interface. Nrog ntau qhov sib cuam tshuam, cov kev xav tau sib sau ua ke txo qis qhov sib txawv thiab ua kom pom kev ci ntsa iab.
Dab tsi hloov thaum koj ntxiv Optical Bonding
Kev sib txuas kho qhov muag ua rau qhov sib txawv ntawm huab cua nrog lub pob tshab optical nplaum (xws li OCR kua resin lossis OCA zaj duab xis). Qhov no tshem tawm sab hauv qhov chaw cuam tshuam los ntawm kev sib piv cov txiaj ntsig refractive ntawm cov khaubncaws sab nraud povtseg.
Qhov tshwm sim yog qhov txo qis hauv kev xav (los ntawm ~ 8% mus rau<1%) and a significant increase in light transmission (often >98%). Hauv ib qhov project logistics davhlau ya nyob twg peb tau tshuaj xyuas, hloov mus rau cov ntawv sib koom ua ke txhim kho sab nraum zoov nyeem tau ntau dua 60% thiab txo cov neeg ua haujlwm tsis txaus siab.
OCR vs OCA
OCR (Optical Clear Resin) yog cov kua nplaum kho nrog UV teeb. Nws ua tau zoo ntawm kev txhaws qhov tsis sib xws thiab feem ntau nyiam rau qhov loj lossis me ntsis nkhaus. OCA (Optical Clear Adhesive) yog ib zaj duab xis, yooj yim dua rau siab - ntim vaj huam sib luag vaj huam sib luag tab sis tsawg dua zam txim rau qhov tsis zoo ntawm qhov chaw.
