Thaum yuav cov cuab yeej loj, xws li TV, koj ib txwm xav paub ntau ntxiv txog nws ntau dua li sau rau ntawm lub khw tus nqi. Niaj hnub no peb yuav qhia koj txog ib txoj hauv kev zoo kom tau txais me ntsis ntxiv ntawm cov ntaub ntawv no - koj tsuas yog yuav tsum tau txiav txim siab lub npe ntawm LG TVs. Cia peb txheeb xyuas ob qho piv txwv thiab lub ntsiab lus ntawm txhua qhov kev xaiv uas twb muaj lawm.
LG TV Designations
TV cim feem ntau yog qhia rau ntawm tus nqi, yog li koj tuaj yeem nrhiav thiab txiav txim siab nws txawm tias tsis muaj kev pab los ntawm tus pab muag. Rau cov cuab yeej LG, nws zoo li qhov no:
LG 00 A B 2 3 4 C where:
- 00 - thawj ob tus lej qhia qhov loj ntawm TV zaub (hauv ntiv tes);
- A - cov lej tsiaj ntawv ntawm lub vijtsam matrix ntau yam;
- В - tsab ntawv code ntawm lub xyoo thaum tus qauv no tau tsim;
- 2 - series uas lub cuab yeej belongs;
- 3 - serial tooj ntawm tus qauv hauv koob;
- 4 - tus lej qhia txog kev hloov pauv hauv kev tsim;
- С - tsab ntawv code ntawm matrix hom, nws daws teeb meem, digit altuner.
Thov nco ntsoov tias daim ntawv lo ntawm LG OLED TVs txawv me ntsis ntawm qhov pom:
OLED 00 A 1 B qhov twg:
- OLED - TV zaub hom;
- 00 - npo kab pheeb suab hauv ntiv tes;
- A - tus naj npawb ntawm tus qauv zoo hauv kev tsim;
- 1 - lub xyoo thaum tus qauv no tau qhia los ntawm cov neeg tsim khoom;
- B - tuner hom ntawm lub cuab yeej.
Tam sim no koj tuaj yeem mus rau qhov kev tshuaj xyuas ntxaws ntxiv ntawm txhua yam
Display size
Nws yooj yim ntawm no. TV LG 42 … yog ib qho khoom siv nrog lub vijtsam kab pheeb ces kaum ntawm 42 ntiv tes. Kev siv: 1 nti yog 2.54 cm. Display qhov ntev muaj qhov cuam tshuam ncaj qha rau tus nqi, yog li txawm tias ob peb ntiv tes sib txawv tuaj yeem cuam tshuam rau tus nqi.
Cov qauv muag sai tshaj plaws yog 32-50 nti. Ntau thiab ntau tus neeg yuav khoom nres ntawm 55-nti npo. Yog li ntawd, LG 42 TV …, uas peb tau qhia hauv qhov piv txwv, yog tus qauv nruab nrab ntawm cov yam ntxwv no.
TV npo hom
Qhov thib ob ntawm tus qauv kos npe hais tias cov hauv qab no:
- P - pem hauv ntej ntawm koj yog lub plasma vaj huam sib luag.
- C - LCD (kua siv lead ua TV) nrog fluorescent backlight.
- L - LCD TV nrog LED backlight (LED teeb).
- U - Ultra HD LED-backlit LCD.
- E, EC - OLED zaub (txog 2016, tom qab ntawd cov qauv pib raug xaivcim OLED …, uas peb tau tshuaj xyuas hauv ntu dhau los).
- S - 2017 Innovation Super UHD TV nrog Nano Cell
- (LG) LF - siab zoo Full HD TVs.
- UF yog 4K tiaj tus TV.
- EF yog 4K vaj huam sib luag OLED TV.
- EG - OLED TV, tab sis nrog lub vijtsam concave, nws qhov kev daws teeb meem kuj tsawg kawg yog 4K, thiab matrix yog plaub-xim.
- UB - lub cuab yeej nrog 4K npo daws teeb meem.
- UC - C-kov TV.
- LB - cov khoom siv muaj Full HD npo zoo.
- LY yog ib qho tshwj xeeb rau kev lag luam loj TV siv hauv khw, tsev so, tsev loj, thiab lwm yam.
LCD, ntshav, OLED: qhov zoo thiab qhov tsis zoo
Yog li, hnub no lub tuam txhab muab peb hom TVs:
- LCD (kua siv lead ua kua) - xws li lub vijtsam muaj lub LCD matrix (kua muaju nyob nruab nrab ntawm cov polymers), lub teeb ci, cov xov hlau, lub vaj tse uas cuam tshuam rigidity. Txhua "kua siv lead ua kua" yog ob txheej ntawm cov ntxaij lim dej polarizing, nruab nrab ntawm cov electrodes yog kaw, thiab ntawm lawv, tig, yog txheej ntawm molecules.
- Plasma (SED) - lub npe hu ua roj tso tawm saib xyuas. Lawv txoj haujlwm yog nyob ntawm qhov ci ntawm phosphor nyob rau hauv lub zog ntawm UV rays. Qhov kawg tshwm sim nyob rau hauv ib qho roj ionizedthaum muaj hluav taws xob tawm mus.
- OLED - Hom kev tshuaj ntsuam no yog tsim los ntawm cov organic tebchaw uas muaj peev xwm ua kom pom lub teeb thaum muaj hluav taws xob dhau los ntawm lawv.
Cia peb xav txog qhov zoo thiab qhov tsis zoo ntawm cov qauv LG TV qhia hauv lub rooj.
| Variety | Pros | Cons |
| LCD zaub |
Lub teeb yuag thiab qhov loj ntawm lub cuab yeej. Tsis zoo li cov khoom siv hluav taws xob cathode, tsis muaj flickering, duab tsom qhov tsis xws luag, cuam tshuam hauv qhov pom tseeb thiab geometry ntawm cov duab tshaj tawm. Ntau tus qauv yog tus yam ntxwv los ntawm kev siv hluav taws xob tsawg - nws nyob ntawm lub zog ntawm lub teeb ci lossis LED backlights. |
Daim duab meej tsuas yog ua tau nrog ib qho kev daws teeb meem. Sim duab sib piv thiab qhov tob dub. Qee zaum muaj teeb meem ntawm cov duab tsis zoo ib yam li qhov ci ci. Xyaum tsis tiv thaiv kev puas tsuaj. Qhov teeb meem ntawm "tuag pixel" feem ntau tshwm sim. Kev hloov cov matrices uas tsis yooj yim yog kim heev. Me me tso cai ua haujlwm kub ntau. |
| Plasma TVs |
xim qhov tob. High contrast picture. Glow uniformity ntawm dub thiab dawb. Lub neej ua haujlwm ntev (raws li qee lub tuam txhab, mus txog 30 xyoo). |
Kev siv hluav taws xob ntau dua (piv rau LCD saib). Loj-loj pixels txhais tau tias tsim cov ntxaij vab tshaus loj thiab. Kev kub hnyiab tuaj yeem tshwm sim hauv thaj chaw uas cov duab tseem tso tawm rau lub sijhawm ntev. |
| OLED zaub |
Lub yuag thiab loj. Kev siv hluav taws xob tsawg thaum tswj cov duab siab. Muaj peev xwm tsim cov duab hloov tau. Lub peev xwm los tsim lub vijtsam loj heev TVs. No backlight xav tau. Lub kaum sab xis loj - daim duab pom meej ntawm txhua lub kaum ntse ntse. No inertia, instant teb. High contrast picture. Lub vijtsam tuaj yeem ua haujlwm tau ntau yam: -40 … +70 o C. |
Short diode life. Liab thiab ntsuab cov tebchaw ploj mus qeeb qeeb dua li xiav, uas tuaj yeem cuam tshuam qhov xim ntawm cov duab. Tsis tuaj yeem tsim cov duab 24-ntsis ruaj khov. Tus nqi siab, ua ke nrog qee yam thev naus laus zis |
Tom tau txheeb xyuas cov yam ntxwv ntawm cov ntxaij vab tshaus nthuav tawm, peb txav mus rau kev txiav cov cim.
xyoo kev loj hlob
Tsab ntawv code uas sib raug rau qhov cim ntawm LG TVs rau lub xyoo ntawm kev txhim kho ntawm tus qauv tshwj xeeb tuaj yeem ua raws li hauv qab no:
- J - 2017.
- H - 2016.
