LCD screen xaiv tsis muaj:
1. LCD npo: daws teeb meem, dot suab, nyob; pom zoo, pom tsis zoo; xim; STN, NWS. 2. Tsav hom: tsav IC, nrog lossis tsis muaj IC tswj.
3. Tsav voltage: built-in, sab nraud; positive, negative, voltage tus nqi. 4. Backlight daim ntawv: CCFL, LED, EL; sab nraub qaum, sab nraub qaum. 5. Module qauv: TAB, COG, COB; installation qauv.
6. Interface hom: parallel port 80, parallel port 68, serial port 232, serial port I2C.
7. Thaum xaiv cov kua siv lead ua kua, thawj qhov kev txiav txim siab yog cov ntsiab lus tso saib, thiab dot matrix yog txiav txim siab raws li cov ntsiab lus tso saib; Thib ob, cov kua siv lead ua kua loj (nrog rau cov duab thiab cov duab zoo) yog txiav txim siab raws li cov qauv; thiab siv ib puag ncig: kub, lub teeb, av noo, mechanical zog Etc. Tsis tas li ntawd, xaiv a) raws li cov teeb pom kev zoo ntawm kev siv ib puag ncig, hom kev cuam tshuam (tsis muaj backlight, teeb pom kev zoo lossis nruab hnub siv), haum Bright sab nraum zoov. b) Transflective hom (nrog backlight, lub teeb lossis tsaus), lub teeb rov qab tuaj yeem qhib thiab tawm raws li lub teeb, haum rau siv sab nraum zoov. c) Transmissive hom (nrog backlight, lub teeb los yog tsaus), lub backlight yuav tsum tau qhib, tsis haum rau sab nraum zoov.
8. Rau cov av noo siab thiab kev siv tshuab ua haujlwm siab: TAB lossis COG cov khoom raug pom zoo, txoj kev sib txuas yog qhov txhim khu kev qha, thiab micro-corrosion tsis yooj yim tshwm sim. dab noj hnub).
Thib ob, raws li CPU cov peev txheej, xaiv txoj kev sib tshuam, seb lub LCD module puas muaj tus tswj hwm hauv: Ntau ARM chips tam sim no muaj cov tswj LCD hauv. Koj tuaj yeem xav txog tus nqi thiab xaiv qhov tsim nyog LCD module. Feem ntau, LCD module tsawg dua 128 kab, thiab nws tsis tas yuav tsum tau. Cov kua siv lead ua kua tshwj xeeb, hom kua siv lead ua kua siv lead ua IC sib xyaw ua ke ntawm kev tsav tsheb thiab kev tswj hwm, xws li S6B0108, SED1520, S6B1713, S6B0741, SED1565, thiab lwm yam, los ntawm 128 kab mus rau 240 kab, kev tsav tsheb IC thiab tswj IC feem ntau yog siv. Cov tsav tsheb ICs xws li S6B0086, NT7701, T6A39, thiab lwm yam, feem ntau siv monochrome (tsis muaj grey scale) tswj ICs yog T6963, SED1335, RA8802, thiab lwm yam.
9. Kev sib piv ntawm STN thiab FSTN: FSTN yog nrawm dua, nrog qhov zoo sib xws thiab pom lub kaum ntse ntse, haum rau cov kab siab suav, thiab tus nqi 10-20% siab dua STN. Xim thiab xim tom qab sib txawv me ntsis; Kev sib piv ntawm TAB thiab COB: TAB kev twb kev txuas yog txhim khu kev qha, cov qauv yog ultra-nyias, lub zog noj tsawg heev, tus qauv lub zog yog tsawg, thiab cov kev cuam tshuam tsis muaj zog; COB qauv yog siab zog, tus qauv yog hnyav, txoj kev sib txuas yog tsis zoo, thiab lub zog noj yog haum rau desktop computers.
10. Kev sib piv ntawm ob peb backlights:
CCFL: Haum rau loj thiab nruab nrab-qhov loj me transmissive kua muaju, xav tau lub teeb qhia daim hlau, siab brightness, ntev lub neej, thiab inverters.
LED: Haum rau me me thiab nruab nrab cov kua siv lead ua kua, xav tau lub teeb qhia phaj, siab brightness, lifespan txog li 50,000 H, feem ntau tsis xav tau lub zog siab. EL: Haum rau me me thiab nruab nrab LCDs, ultra-nyias (tsawg dua 0.4mm), tsis tshua muaj ci, tsis muaj zog noj, lub neej luv (2000H)
