Pansipa tikuwonetsa mawonekedwe osiyanasiyana azithunzi za TFT LCD mwatsatanetsatane:

(1) Yaikulu: m'badwo woyamba wa gawo lapansi lalikulu lagalasi (3000mmx400mm) TFT koyambirira kwa zaka za m'ma 1990, gawo lagawo la galasi lidakulitsidwa mpaka 6800mmx880mm mu theka loyamba la 2000, ndi galasi la 950mmx1200mm layikidwanso gawo lapansi. posachedwapa.

(2) Kuphatikiza kwakukulu: Chisankho cha LCD purojekiti ya 1.3-inch TFT display chip ndi XGA, yomwe ili ndi mamiliyoni a pixels. Chisankho chake ndi . Makulidwe a kanema wa 16.1-inch TFT amorphous silicon ya SXGA (1280x1024) ndi ma nanometer 50 okha. Kuphatikizika kwaukadaulo kwa TABONGLAS ndi SYSTEMONGLASS, zofunikira zaukadaulo pazida ndi zoperekera, komanso zovuta zaukadaulo ndizokwera kuposa za LSI zachikhalidwe.

(3) Ntchito zonse: TFT madzi crystal anasonyeza poyamba ankagwiritsa ntchito masanjidwewo adiresi kusankha dera, amene bwino makhalidwe a madzi galasi valavu kuwala. Pazowonetsera zowoneka bwino, chophimba cha LCD chikhoza kukwaniritsa mawonekedwe apamwamba, okwera kwambiri posintha magetsi mumtundu wa V 0-6 (mtengo wake wamba ndi 0.2 ~ 4V) ndikuwongolera moyenera chinthu chomwe mukufuna.

(4) Mtengo wotsika: Magawo a galasi ndi magawo apulasitiki amathetsa vuto lamtengo wapatali la ma semiconductor ophatikizika akuluakulu ndikutsegula malo ogwiritsira ntchito mabwalo akuluakulu ophatikizika a semiconductor.

(5) Kusinthasintha kwa ndondomeko: Kuwonjezera pa sputtering, laser annealing technology, CVD (chemical vapor deposition) MCVD ingasankhe filimu ya amorphous, filimu yopangidwa ndi zinthu zambiri ndi filimu imodzi yokha kuwonjezera pa mapangidwe amtundu wa filimu monga molecular chemical vapor deposition. Sikuti amatha kuchita filimu ya silicon, komanso kuchita zinthu zina. Mafilimu a I-VI ndi tetra-V semiconductor.

M'magawo ambiri ogwiritsira ntchito, LCD liquid crystal display screen yotengera ukadaulo wa TFT ndiye mzati wa gulu lazidziwitso, ndipo itha kugwiritsidwanso ntchito pakukulitsa mwachangu ma transistors a kanema woonda. (TFT-OLED) mawonekedwe apamwamba.
