TFT-screen - zoo thiab tsis zoo

Kua siv lead ua qhia yuav luag yuam tawm ntawm lub lag luam ua ntej lawm CRT saib. Qhov no yog vim tus tseem ceeb zoo muaj los ntawm lub tshiab TFT-screen.

Qhov zoo ntawm cov TFT-technology

Ib tug ntawm lub ntsiab zoo - cov tsis muaj geometric distortion, uas rau ib ntev lub sij hawm, tab sis yuav luag unsuccessfully tiv thaiv developers CRT cov ntxaij vab tshaus. Tej TFT-screen monitor los yog ib tug ca lub zoo, uas excludes lub xub ntiag ntawm distortions zoo li cov fab thiab nyob rau hauv lub center.

Tsis muaj tsawg tseem ceeb hauv lub qhaj ntawv ntawm flicker, uas yog nyob rau ntawm ib zaus saum toj no 85 Hz tus tib neeg qhov muag yuav tsis paub qhov txawv, tab sis nws yog tam sim no, tsim ib tug tseem ceeb hom rau lub ob lub qhov muag. TFT screen tsis flicker. Thaum hloov cov illumination duab yog ib tug kev hloov (hloov ntawm cov kev taw qhia los ntawm cov refraction ntawm lub teeb).

TFT screen tshuab tau zoo heev txo lub theem ntawm electromagnetic tawg. Tej yam ntawm no hom ntawm hluav taws xob nyob rau hauv tib neeg lub cev yog tseem tsis tau tag nrho to taub, tab sis zaum pom zoo hais tias nws yog kom meej meej tsis yog li ntawd pab tau. Yog li ntawd, lub sab lub electromagnetic tawg, lub zoo dua. Thiab TFT-screen muaj ib feem ntawm nws cov npaum li cov yav tas los siv technology. Qhov no feature tso cai rau lawv mus siv saib thiab TFT cov ntxaij vab tshaus nyob rau hauv cov tsev kho mob, nyob rau hauv factories, nyob qhov twg ntxias suab nrov yuav adversely cuam tshuam rau ib tug ntau yam dab, lub lag luam ntawm lwm yam khoom.

Lwm plus - lub me me luaj li cas thiab lub teeb yuag, uas yog txawv TFT-screen. Qhov no saib yuav tau muab dai rau ntawm phab ntsa, ces nws yeej yuav tsis muab qhov chaw. Qhov no yog tshwj xeeb tshaj yog muaj tseeb nyob rau hauv lub txwv qhov chaw los yog qhov chaw uas xws li noog ntau tshaj ib tug teb. Lub piggy zoo zog yuav tsum tau ntaus nqi kom tsawg zog noj thiab me me thaum tshav kub kub tiam thaum lub sij hawm lub lag luam. Qhov no dua puas tau ho rau loj pawg ntawm saib nyob rau hauv tib chav. Me tshav kub tso cai rau kom txuag tau lub koom haum ntawm cua thiab lub zog tau rau nws ua lag luam, uas tsis muaj zog noj tej yam hluav taws xob nqi (TFT-screen kov 3-4 lub sij hawm tsawg zog dua nws cov thawj CRT).

Cov ntxaij vab tshaus uas siv cov TFT-technology, ntau txhim khu kev qha dua lawv CRT analogs uas yog siv nyob rau hauv high voltage, uas feem ntau ua rau breakages. Kua siv lead ua technology yog siv currents ntawm me me qhov ntau, uas tsub kom lawv muaj kev cia siab.

Tsis zoo ntawm cov TFT-technology

TFT-transistors muaj ib co tsis zoo, thiab thawj ntawm lawv - tus nqi siab. Tab sis lub savings rau hluav taws xob, tsis tshua muaj tshav kub tawg thiab siab ntseeg (raws li ib tug tsim nyog tau - cov tsis muaj tus kho cov nqi) sai sai them ib tug ntxiv nqi uas yog tsim nyog rau kis tau tus purchase.

Tom ntej no rho tawm - ntawm ambient kub cov kev txwv ntawm qhov nruab nrab. Tab sis qhov no siv ntau rau cov muaj kev siv cov ntxaij vab tshaus TFT: lawv yuav siv tsis tau nyob rau hauv kub khw thiab thaum uas tsis muaj kub, uas koj yuav pom zoo, tsis yog qhov tseem ceeb rau lub tsev siv.

Qhov tsis zoo ntawm lub xub ntiag ntawm "tuag" pixels yuav tsum tau ntaus nqi kom tshwm sim ua ntej los yog tom qab ntawd. Qhov no, ntawm chav kawm, tsis kaj siab, tab sis tsis tuag. Yog hais tias ob peb txhiab ntsiab lus ib ob peb daim mus down (nws tag nrho thiab xws li nqi yuav tsum raug xam), ces lawv yuav tau txais nyob rau hauv lub txoj kev los sis tsis nyob rau hauv tag nrho, los sis yuav muaj heev me me.
