Dab tsi yog 7 Nti TFT LCD Screen?
TFT stands rau Thin Film Transistor. Nws yog ib qho khoom siv siab heev ntawm LCD (Liquid Crystal Display) technology. Txhua pixel muaj nws tus kheej me me transistor uas tswj cov kua muaju kom meej meej. Qhov no ua rau lub sijhawm teb sai dua, qhov tseeb xim zoo dua, thiab cov duab zoo dua piv rau cov laus dua qub -matrix LCDs.
Hauv cov ntsiab lus yooj yim: TFT LCDs xa cov xim vibrant thiab ua haujlwm du, ua rau lawv zoo tagnrho rau txhua yam xav tau lub vijtsam meej, teb.
Vim li cas 7 nti?
Qhov loj 7-inch hits qhov sib npaug zoo meej. Nws yog qhov loj txaus rau kev nyeem tau yooj yim thiab cov duab ntxaws tab sis compact rau cov khoom siv txav tau yooj yim lossis qhov chaw txwv. Qhov loj me no ua haujlwm zoo rau cov cuab yeej tuav, tsheb dashboards, ntse vaj huam sib luag, thiab DIY tej yaam num. Nws muab cov vaj tse txaus tsis muaj lub zog kos lossis tus nqi ntawm cov ntxaij vab tshaus loj.
Yuav ua li cas ib7 TFT LCD Xim Zaubua tau
Lub 7-inch TFT LCD siv lub teeb nraub qaum (feem ntau LED) ci ntsa iab los ntawm cov kua siv lead ua kua. TFT transistors tswj txhua pixel lub teeb pom kev thiab xim lim (RGB) tsim cov duab puv xim. Niaj hnub nimno versions feem ntau suav nrog cov khaubncaws sab nraud povtseg rau kev sib tham sib siv.

Kev daws teeb meem - tus lej twg tseem ceeb?
Cov kev daws teeb meem rau 7-nti TFT LCDs suav nrog
800x480 (WVGA): Zoo rau qhov yooj yim interfaces thiab nqi -sensitive tej yaam num.
1024x600 (WSVGA): Nrov qab qhov chaw rau cov ntawv nyeem thiab cov duab.
1280x800 lossis siab dua (txog 1200x1920 hauv qee cov qauv): Zoo tagnrho rau cov ncauj lus kom ntxaws los yog daim ntawv thov hwm.
Kev daws teeb meem siab dua txhim kho qhov pom tseeb tab sis nce kev xav tau thiab tus nqi.
Brightness (nits) thiab qhov sib piv piv
Kev siv sab hauv tsev: 300-500 nits.
Sab nraum zoov lossis siab -ambient light: 800–{2}} nits rau hnub ci nyeem tau.
Qhov sib piv piv feem ntau yog li ntawm 500: 1 txog 1500: 1 lossis zoo dua hauv IPS variants.
Saib lub kaum sab xis, kov xaiv, thiab hom interface
Saib cov ces kaum: TN vaj huam sib luag muab cov kaum nqaim; IPS versions muab qhov dav (txog 178 degree) saib.
Kov: Resistive (stylus/pressure) los yog capacitive (ntau-kov, ntiv tes- phooj ywg).
Interfaces: RGB, LVDS, MIPI, HDMI (nrog adapter boards), SPI.
Kev khiav hauj lwm qhov kub thiab txias (tshwj xeeb tshaj yog siv rau kev lag luam)
Industrial-qib cov ntxaij vab tshaus feem ntau ua haujlwm -20℃rau +70℃(los yog dav dua). Xyuas qhov no rau qhov chaw hnyav.

7 Nti TFT LCD vs Lwm Hom Zaub Qhov txawv tiag tiag yog dab tsi?
TFT LCD vs IPS LCD
IPS yog ib qho subtype ntawm TFT LCD. Tus qauv TFT (feem ntau TN-raws li) yog pheej yig dua nrog cov lus teb sai dua tab sis pom cov kaum sab xis. IPS muab cov xim zoo dua thiab pom dav ntawm tus nqi siab dua me ntsis.
TFT LCD vs OLED
TFT LCDs yog ci dua nyob rau hauv tshav ntuj ncaj qha, tus nqi ntau dua - zoo, thiab muaj lub neej ntev dua nyob rau hauv siab - qhov ci ci. OLED muab cov xim dub zoo meej, qhov sib txawv siab dua, thiab cov ntaub nyias nyias tab sis raug nqi ntau dua, muaj kev pheej hmoo hlawv -hauv, thiab ua haujlwm tsis zoo nyob rau sab nraum zoov.
TFT LCD vs HDMI saib (rau embedded siv)
Dedicated 7-nti TFT modules yog optimized rau tsawg zog, ncaj qha kev koom ua ke, thiab embedded interfaces. Tag nrho HDMI saib yog yooj yim rau kev txuas tab sis bulkier thiab tsis tshua muaj txiaj ntsig rau cov haujlwm kev cai.
