Izibonisi ze-IPS-LCD ziphakeme kunezibonisi ze-TFT-LCD
I-IPS isichazamazwi sokushintsha kwe-plane, okuyinto ubuchwepheshe beskrini esetshenziselwa izikrini ze-LCD . Ukushintshwa kwezindiza kwaklanyelwe ukubhekana nokulinganiselwa ezikrinini ze-LCD ngasekupheleni kweminyaka engama-1980 ezazisetshenziselwa umthamo we-nematic field osontekile. Indlela ye-TN yayiwukuphela kobuchwepheshe obukhona ngesikhathi se-LCDs esebenzayo yamatriy TFT ( Thin Film Transistor ). Ukulinganiselwa okuyinhloko kwe-nematic yomsindo we-matrix yamatrikhi ama-LCD afaka umbala ophansi kanye ne-angle encane yokubuka. I-IPS-LCDs inikeza ukukhiqizwa kombala ongcono kanye nama-angles wokubuka okubanzi.
I-IPS-LCDs isetshenziswa kakhulu kuma-smartphones ephakathi ne-high-end namadivayisi aphathekayo. Zonke i-Retina Display Apple iPhones zifaka i-IPS-LCD, njenge-Motorola Droid namanye ama-TV namaphilisi.
Ukwaziswa ngezikhangiso ze-IPS
Ama-IPS-LCD afaka ama-transistors amabili kumaphikseli ngayinye, kuyilapho i-TFT-LCD isebenzisa eyodwa kuphela. Lokhu kudinga i-backlight enamandla kakhulu, ehlinzeka ngemibala enembile futhi ivumela isibuko ukuthi sibukwe kusukela ku-angle ekulu.
Ama-IPS-LCD awabonisi lapho isikrini sithintekile, ongase ubone kwabanye abaqaphi abadala. Lokhu kunenzuzo ikakhulukazi ekubukeni kwesikrini sokuthinta njengalabo abakwi-Smartphones kanye ne-laptops yokuthinta isikrini.
Ukukhathazeka ukuthi i-IPS-LCD idla amandla angaphezu kwe-TFT-LCD, mhlawumbe kuze kube ngu-15% ngaphezulu. Bayazibiza kakhulu futhi benze izikhathi eziningi zokuphendula.
I-IPS Intuthuko Yezobuchwepheshe
I-IPS iye yahamba ngezinombolo zezigaba zentuthuko ngaphakathi kwe-Hitachi ne-LG Display.
- I-Hitachi yandisa i-angle yokubuka ne-Super TFT (IPS) ngo-1996.
- Iphinde ikhishwe i-Super-IPS (S-IPS) ngo-1998 ukuze isuse ukushintsha kombala.
- Ngonyaka we-2001, i-Advanced Super-IPS (AS-IPS) ithuthukise ukuthunyelwa kwe-100/100 (ngo-1996) kuya ku-130/250.
- I-Hitachi yenza ngcono ukuhluka okuhlukile phakathi kuka-2004, 2008 no-2010 ngokukhishwa kwe-IPS-Provectus, i-IPS Alpha, ne-IPS Alpha engokwesini esilandelayo.
Umzila wesikhathi we-IPS wobuchwepheshe be-LG Display ubukeka kanje:
- Isilinganiso sokungafani sathuthukiswa ngo-2007 nge-Horizontal IPS (H-IPS).
- I-IPS eyithuthukisiwe (E-IPS) ithuthukise i-angle yokubukela futhi yanciphisa isikhathi sokuphendula ema-millisecond amahlanu, kanti futhi ikhulisa ukuvula ukuhanjiswa kokukhanya. Yakhishwa ngo-2009.
- Ngo-2010 wabona i-IPS yeProfesa (P-IPS), eyanikeza imibala engaphezu kwezigidi eziyizinkulungwane kanye nama-orientation amaningi nge-pixel ngayinye. I-IPS-Pro ihamba phambili kakhulu futhi iyabiza.
- Ukubonisa kwe-LG kukhishwe i-Advanced High-Performance IPS (AH-IPS) ngo-2011 ukuthuthukisa ukunemba kombala, ukwandisa isinqumo, futhi unikeze ukukhanya okwengeziwe lapho kumodi yamandla aphansi.
IPS Alternatives
I-Samsung iqalise i-Super PLS (Ukushintshwa kwe-Plane-to-Line) ngo-2010 njengenye indlela eya ku-IPS. Kufana ne-IPS kodwa ngezinzuzo ezengeziwe ze-angle yokubukela okungcono, ukunyuka kokukhanya kwezingxenye ezingu-10, iphaneli eguquguqukayo, ikhwalithi yesithombe engcono, kanye nezindleko eziphansi ezingamaphesenti angu-15 kune-IPS-LCDs.
Ngonyaka ka-2012, i-AHVA (i-Advanced Hyper-Viewing Angle) yaqaliswa yi-AU Optronics ukuhlinzeka nge-IPS ehlukile efaka amaphaneli e-IPS kodwa ngezinga eliphezulu lokuvuselela .
