Touchscreen ntsiav tshuaj. lus qhia dav dav

Touchscreen ntsiav tshuaj yog ib qhov tseem ceeb Cheebtsam. Peb yuav hais yuav tsum muaj. Yog hais tias tsis nws, ces ua hauj lwm nrog cov gadget yuav nqa tawm los ntawm cov neeg kho tshuab tswj.

Yuav ua li cas yog no

Touchscreen ntsiav tshuaj, los yog lwm yam khoom - nws yog ib tug txhais tau tias nkag mus kawm ntaub ntawv. Qhov no ntaus ntawv yog ib qho screen uas reacts mus ib kov thereto. Nws yog lub luag hauj lwm rau ua ntaub ntawv foob ib qhov system operating los yog daim ntawv thov rau cov gadget Pib ntsais koj teeb. Yog hais tias peb kos ib analogy, qhov kov screen - ib tug nas thiab keyboard rau koj cov ntsiav tshuaj.

Hom:

• Resistive. Qhov no hom ntawm kov screen yog ib tug pob tshab daim nyias nyias yog coated nrog ib tug conductive txheej, uas yog nyob rau hauv lub khob muaj tib txheej. Cov kev khiav hauj lwm hauv paus ntsiab lus ntawm no ntaus ntawv yog heev yooj yim. By nias tus ntiv tes los yog stylus rau qhov kev tshuaj ntsuam no tshwm sim kaw membrane thiab iav hauv ib lub point, uas lub voltage hloov nyob rau ntawd. Lub microprocessor no cov deeg thiab laij coordinates. Qhov no kov screen muaj ib tug uas tsis muaj nqi. Tsis tas li ntawd nyob rau hauv nws haum yog tau lo lus teb rau kov tej khoom. Tab sis nws muaj ib tug uas tsis muaj lub dag lub zog thiab ib tug me me ua hauj lwm lub neej, uas yog hais txog 35 lab keystrokes rau txhua kis. Thiab - cia li raws li cov tseem ceeb - cov tsis muaj kev siv ntawm cov multi-kov tuition. Tsis tas li ntawd, cov ua hauj lwm ntawm no zaub yog nrog los ntawm ib tug loj tus naj npawb ntawm uas tsis nyob rau hauv kev ntawm cov gestures "swb" thiab "flipping". Qhov no technology yog tsis muaj dav siv nyob rau hauv cov ntsiav tshuaj. Niaj hnub no, koj yuav nrhiav tau ib tug neeg ntaus ntawv qauv, txawm peem rau nrog ib tug zoo xws li cov kov screen. Piv txwv li, ib tug kov screen rau ntsiav tshuaj "TEXET TM-7020".
• Capacitive. Qhov no yog tus thib ob cov txheej txheem, los ntawm cov uas tsim kov ntxaij. Ua hauj lwm nrog xws kov ntxaij yuav tsuas yuav ib tug ntiv tes los yog los ntawm kev siv ib tug conductive stylus. Qhov no hom ntawm kev kov cov ntxaij vab tshaus yuav tau muab faib ua ob pawg: cov pa thiab projective-capacitive. Nyob rau hauv thawj hom kev ntaus ntawv yog thov mus rau lub iav neeg xyuas pib txheej. Nyob rau ntawm cov ces kaum hauv cov zaub electrodes yog muab tso rau uas nkag alternating voltage mus rau lub txheej. Thaum koj kov qhov screen nrog koj cov ntiv tes muaj to tam sim no. Lub microprocessor tsom kwm lub point ntawm kev sib cuag. Qhov no yog accomplished los ntawm kev hloov nyob rau hauv lub electrode readings, raws li cov uas nyob ze ntawm lawv yog heev zog amperage thiab kuj tau tsawg. Tag nrho cov multi-kov rau no hom ntawm cov ntxaij vab tshaus kom tau yuav tsis ua hauj lwm.
• Ntau advanced technology yog ib tug projection-capacitive. Lub sab hauv sab ntawm cov zaub nyob rau hauv cov ntaub ntawv no yog them los ntawm ib daim phiaj electrode. Thaum kov, ib tug ntawm lawv tsim los ntawm ib tug capacitor, capacitance uas yog tau ua thiab muab xam los ntawm coordinates. Qhov no technology ua rau nws tau los siv rau ib tug tag nrho cov multitouch. E. Peev xwm ntawm txhawb xws li ib tug zaub 2, 5 los yog txawm 10 simultaneous touches. Ib tug piv txwv ntawm kev siv ntawm no technology yog lub touchscreen ntsiav tshuaj "EXPLAY tub cheev xwm 9,71".

mounting xaiv

Teem qhov kov screen rau lub gadget yog ua los sib nplaum. Touchscreen ntsiav tshuaj mounted yog rau qhov kev tshuaj ntsuam los yog nyob rau hauv lub cev. Nyob rau hauv thawj cov ntaub ntawv, cov nplaum neeg sawv cev yuav tau mus thov tsuas yog nyob rau hauv lub puag ncig los yog nyob rau hauv tag nrho screen. Nyob rau hauv lub thib ob cov ntaub ntawv, nws yog faib nyob rau hauv lub cev qhov chaw uas yog nyob rau hauv kev tiv tauj sensor.

cov ntaub ntawv uas

Touchscreen ntsiav tshuaj tej zaum yuav ua los ntawm iav los yog yas. Nyob rau hauv thawj cov ntaub ntawv, qhov kov screen muaj qis zog lub zog. Ntxiv mus, thaum nws yog puas sai li sai tau pom tej kab nrib pleb. Devices ua los ntawm yas, check ntau. Thiab thaum puas tej kab nrib pleb tsis zoo li.
