Icyapa cy'urumuri cya acrylic n'icyapa cy'urumuri cya PS ni ubwoko bubiri bw'ibikoresho by'urumuri bikunze gukoreshwa muriAmatara ya LEDHariho itandukaniro n'inyungu zimwe na zimwe hagati yabyo.

Ibikoresho: Isahani y'urumuri rwa acrylic ikozwe muri polymethyl methacrylate (PMMA), naho isahani y'urumuri rwa PS ikozwe muri polystyrene (PS).

Umusaruro urwanya imirasire ya UV: Ikirahure cy'urumuri cya acrylic gifite ubushobozi bwiza bwo kurwanya imirasire ya UV, gishobora kugabanya neza ikibazo cy'umuhondo iyo kimaze igihe kirekire. Ikirahure cy'urumuri cya PS ntabwo kirwanya cyane imirasire ya UV kandi gikunda guhinduka umuhondo.

Imikorere yo kohereza urumuri: Ikirahure cy'urumuri cya acrylic gifite ubushobozi bwo kohereza urumuri rwinshi, gishobora gukwirakwiza urumuri rwa LED ku gipande cyose no kugabanya igihombo cy'urumuri. Imikorere yo kohereza urumuri ya PS light guide plate ni mibi, ibi bikaba bishobora gutera ikwirakwizwa ry'urumuri ritaringaniye no gupfusha ubusa ingufu.

Ubunini: Isahani y'urumuri rwa acrylic ni nini cyane, akenshi iri hejuru ya mm 2-3, kandi ikwiriye amatara ya LED afite urumuri rwinshi. Isahani y'urumuri rwa PS ni nto cyane, akenshi iri hagati ya mm 1-2, kandi ikwiriye amatara mato.

Muri make, ibyiza by'amatara ya acrylic ayobora amatara birimo kurwanya imirasire ya UV neza, ubushobozi bwo kohereza urumuri rwinshi kandi akwiriye amatara manini, mu gihe amatara ya PS ayobora amatara akwiriye amatara mato. Amatara ya PS ayobora amatara agomba guhitamo agomba kugenwa hakurikijwe ibyo akeneye n'ingengo y'imari.
