Cov ntawv thov sab nraum zoov xav tau cov lus pom uas tseem pom tau meej txawm tias nyob rau hauv lub hnub ncaj qha thaum tiv thaiv los nag, plua plav, thiab kub heev. Ib tug zoo-engineered 7-nti Waterproof Touch Screen LCD ua ke nrog lub teeb ci siab, kho qhov muag kho qhov muag, thiab kev sib khi kom zoo kom xa cov kev ua tau zoo.
Teeb meem nyeem hnub ci
Yuav ua li cas rau ib tug qauv LCD npo nyob rau hauv ncaj qha tshav ntuj
Cov ntxaij vab tshaus txheej txheem tau ntxuav tawm, qhov kev xav tau tswj hwm, thiab qhov sib txawv tawg, ua rau cov ntawv nyeem thiab cov duab ze ze pom.
Qhov xwm txheej tiag tiag: cov kws tshaj lij hauv teb tsis tuaj yeem nyeem cov zaub thaum tav su
Ib lub tuam txhab tsim khoom siv tau txais kev tsis txaus siab uas cov neeg ua haujlwm tsis tuaj yeem nyeem cov tshuab ntawm lawv cov 7-nti cov ntxaij vab tshaus thaum nruab hnub, ua rau muaj teeb meem kev nyab xeeb thiab poob qis.
Cov kev tshawb fawb tom qab yog vim li cas lub teeb ambient defeats qis -brightness panels
High ambient teeb overwhelms qhov screen lub luminance, txo qhov zoo sib xws.
Vim li cas kev daws qhov teeb meem no muaj ntau dua li tsuas yog tig lub teeb rov qab
Ntau cov txheej txheem ntxiv - ci ntsa iab, kev sib txuas, txheej, thiab kev sib khi - yog xav tau rau kev ua tau zoo sab nraum zoov.
Tib neeg lub qhov muag thiab cov ntxaij vab tshaus LCD yuav ua li cas rau lub teeb ci
Yuav ua li cas tib neeg lub qhov muag hloov mus rau ambient lub teeb (cov tub ntxhais kawm ntawv cog lus hauv paus)
Nyob rau hauv qhov kaj, cov menyuam kawm ntawv cog lus, ua rau nws nyuaj rau pom qis dua -luminance displays.
Kev sib tw luminance: screen brightness vs ambient lux theem
Lub vijtsam yuav tsum sib tw nrog ib puag ncig lub teeb siv.
Vim li cas 1000 lux sab hauv tsev zoo li ci tab sis 100,000 lux sab nraum zoov tua qhov pom kev
Sab nraum lub teeb theem yog qhov siab dua.
Qhov sib piv piv yog vau nyob rau hauv ncaj qha tshav ntuj
Yog tsis muaj kev kho mob kom zoo, cov zaub qhov sib piv piv tau poob qis hauv qhov kaj.

Txoj kev 2 - Optical Bonding
Optical bonding yog dab tsi thiab nws ua haujlwm li cas
Optical bonding ua rau huab cua sib txawv ntawm LCD thiab kov / npog iav nrog pob tshab nplaum.
Huab cua sib txawv vs tag nrho cov khoom sib koom ua ke - qhov pom qhov sib txawv tau piav qhia
Bonded qhia tshem tawm cov kev xav sab hauv kom muaj qhov sib txawv ntau dua.
Yuav ua li cas kho qhov muag bonding txo qhov kev xav sab hauv los ntawm 75%
Nws dramatically txhim kho kev nyeem ntawv nyob rau hauv lub teeb ci.
Tus nqi cuam tshuam ntawm optical bonding ntawm 7 nti LCD module nqi
Ntxiv 15-40% rau module nqi tab sis zoo heev txhim kho kev ua tau zoo.
Cov ntawv thov twg xav tau kev sib txuas kho qhov muag
Sab nraum zoov kiosks, khoom siv marine, thiab tsheb.
