IPS yog cov lus luv rau kev hloov pauv hauv lub dav hlau, uas yog lub vijtsam tshuab siv nrog cov ntxaij vab tshaus LCD. Kev hloov hauv dav hlau tau tsim los daws cov kev txwv hauv cov ntxaij vab tshaus LCD ntawm xyoo 1980s uas tau siv qhov sib tw nematic teb cov nyhuv matrix. Txoj kev TN yog tib lub thev naus laus zis uas muaj nyob rau lub sijhawm rau active matrix TFT (Thin Film Transistor) LCDs. Cov kev txwv tseem ceeb ntawm twisted nematic teb cov nyhuv matrix LCDs yog cov xim tsis zoo thiab lub kaum sab xis pom. IPS-LCDs xa cov xim zoo dua qub thiab pom cov kaum sab xis.
IPS-LCDs feem ntau siv rau hauv nruab nrab thiab qib siab smartphones thiab cov khoom siv nqa tau yooj yim. Txhua Retina Display Apple iPhones muaj IPS-LCDs, zoo li Motorola Droid thiab qee lub TV thiab ntsiav tshuaj.
Cov ntaub ntawv ntawm IPS Displays
IPS-LCDs muaj ob lub transistors rau txhua pixel, thaum TFT-LCDs siv ib qho xwb. Qhov no yuav tsum muaj lub teeb pom kev zoo dua, uas muab cov xim muaj tseeb dua thiab cia lub vijtsam saib los ntawm lub kaum sab xis.
IPS-LCDs tsis pom thaum lub vijtsam tau kov, uas koj tuaj yeem pom hauv qee qhov qub saib. Qhov no yog qhov tshwj xeeb tshaj yog rau cov khoom siv kov-screen zoo li cov hauv smartphones thiab touch-screen laptops.
Qhov kev poob qis yog tias IPS-LCD siv lub zog ntau dua li TFT-LCD, tuaj yeem nce txog 15 feem pua ntau dua. Lawv kuj tseem kim dua los ua thiab muaj sij hawm teb ntev dua.
IPS Advances hauv Technology
IPS tau dhau los ntawm ntau theem kev txhim kho hauv Hitachi thiab LG Display.
- Hitachi nthuav dav lub kaum sab xis saib nrog Super TFT (IPS) hauv xyoo 1996.
- Nws kuj tso tawm Super-IPS (S-IPS) hauv xyoo 1998 kom tshem tawm cov xim hloov.
- Hauv xyoo 2001, Advanced Super-IPS (AS-IPS) txhim kho kev xa tawm los ntawm 100/100 (hauv 1996) txog 130/250.
- Hitachi txhim kho qhov sib piv piv rau xyoo 2004, 2008 thiab 2010 nrog kev tso tawm ntawm IPS-Provectus, IPS Alpha, thiab IPS Alpha tom ntej gen.
LG Display's IPS thev naus laus zis ncua sij hawm zoo li qhov no:
- Qhov sib piv tau txhim kho hauv xyoo 2007 nrog Kab rov tav IPS (H-IPS).
- Txhim kho IPS (E-IPS) txhim kho lub kaum sab xis pom thiab txo lub sijhawm teb rau tsib milliseconds, thaum tseem nthuav dav lub aperture rau lub teeb kis tau tus mob. Nws tau tso tawm xyoo 2009.
- 2010 pom Professional IPS (P-IPS), uas muaj ntau tshaj li ib lab xim thiab ntau qhov kev taw qhia ib pixel. IPS-Pro yog qhov siab heev thiab kim.
- LG zaub tso tawm Advanced High-Performance IPS (AH-IPS) hauv xyoo 2011 los txhim kho xim raug, nce qhov kev daws teeb meem, thiab muab lub teeb ntau dua thaum nyob hauv qis zog hom.
IPS Alternatives
Samsung tau tshaj tawm Super PLS (Plane-to-Line Switching) hauv 2010 ua lwm txoj hauv kev rau IPS. Nws zoo ib yam li IPS tab sis nrog cov txiaj ntsig ntxiv ntawm qhov pom qhov zoo dua, qhov ci nce ntawm 10 feem pua, lub vaj huam sib luag hloov tau, cov duab zoo dua qub, thiab 15 feem pua tus nqi qis dua IPS-LCDs.
Nyob rau xyoo 2012, AHVA (Advanced Hyper-Viewing Angle) tau qhia los ntawm AU Optronics los muab IPS lwm txoj hauv kev uas muaj IPS-zoo li vaj huam sib luag tab sis nrog cov nqi tshiab dua.
