LCD waa magaca buuxa ee Liquid Crystal Display, badiyaa TFT, UFB, TFD, STN iyo noocyada kale ee bandhig LCD ma heli karaan dhibcaha barnaamijka ee maktabadda Dynamic-link.
Shaashada LCD ee inta badan la isticmaalo waa TFT.TFT (Thin Film Transistor) waxaa loola jeedaa transistor aflaanta khafiifka ah, halkaas oo pixel kasta oo LCD ah uu wado transistor filim khafiif ah oo lagu dhex daray pixel-ka gadaashiisa, awoodna u siinaya xawaaraha sare, dhalaalka sare, iyo muujinta isbarbardhiga sare ee macluumaadka shaashadda.Hadda waa mid ka mid ah aaladaha bandhiga midabka LCD ugu fiican iyo aaladda guud ee soo bandhigta laptops iyo miisaska.Marka la barbar dhigo STN, TFT waxay leedahay dherjin midab aad u fiican, awoodda soo celinta, iyo isbarbardhigga sare.Weli si cad ayaa loogu arki karaa qorraxda, laakiin khasaaraha ayaa ah in ay isticmaasho awood badan oo ay leedahay kharash badan.
Waa maxay LED
LED waa soo gaabinta iftiinka Emitting Diode.Codsiyada LED-ka waxaa loo qaybin karaa laba qaybood: marka hore, muraayadaha LED-yada;Midda labaad waa codsiga ee tube hal LED, oo ay ku jiraan LED backlight, LED infrared, iwm sida formuraayadaha bandhiga LED , Naqshadaynta iyo heerka tignoolajiyada wax soo saarka ee Shiinaha ayaa asal ahaan la mid ah heerarka caalamiga ah.Shaashadda LED-ka waa xaashi qaabeynta kumbuyuutarka oo leh unug bandhigeed 5000 yuan, oo ka kooban arrays LED.Waxay qabataa wadista iskaanka danab yar waxayna leedahay sifooyinka isticmaalka tamarta hoose, nolosha adeeg dheer, kharash yar, dhalaal sare, cillado yar, xagal daawasho oo weyn, iyo masaafo muuqaal dheer.
Farqiga u dhexeeya shaashadda LCD-ga iyo shaashadda LED-ka
bandhigyada LEDwaxay ku leeyihiin faa'iidooyin marka loo eego bandhigyada LCD xagga dhalaalka, isticmaalka awoodda, xagasha daawashada, iyo heerka soo kicinta.Isticmaalka tignoolajiyada LED-ka, waxa suurtogal ah in la sameeyo bandhigyo ka khafiifsan, ka iftiimaya, kana cad cad LCD-yada.
1. Saamiga isticmaalka korantada ee LED ilaa LCD waa qiyaastii 1:10, taasoo ka dhigaysa LED tamar badan.
2. LED-ku wuxuu leeyahay heer cusub oo dib-u-cusbooneysiin ah iyo waxqabad wanaagsan oo muuqaal ah.
3. LED waxay bixisaa xagal daawasho ballaaran oo ilaa 160 ° ah, kaas oo soo bandhigi kara qoraallo kala duwan, lambaro, sawirro midab, iyo macluumaadka animation.Waxay ciyaari kartaa calaamadaha muuqaalka midabka ah sida TV-ga, muqaalka, VCD, DVD, iwm.
4. Xawaaraha falcelinta curiyaha shaqsiga ah ee shaashadaha soo bandhiga LED waa 1000 jeer ka badan shaashadaha LCD LCD, waxaana lagu eegi karaa qalad la'aan hoostooda iftiin xoog leh, waxayna la qabsan karaan heerkulka hoose ee -40 darajo Celsius.
Si fudud loo dhigo, LCD iyo LED waa laba teknoolajiyada bandhig oo kala duwan.LCD waa shaashad muuqaal ah oo ka kooban kiristaalo dareere ah, halka LED-ku yahay shaashad muuqaal ah oo ka kooban daaydhyo iftiin leh.
Iftiinka dambe ee LED: Badbaadinta awoodda (30% ~ 50% ka yar CCFL), qiimo sare, dhalaal sare iyo saturation.
Iftiinka dambe ee CCFL: Marka loo eego iftiinka dambe ee LED, wuxuu cunaa awood badan (wali aad uga yar CRT) waana ka jaban yahay.
Farqiga shaashadda: iftiinka dambe ee LED wuxuu leeyahay midab dhalaalaya iyo dhereg sare (CCFL iyo LED waxay leeyihiin ilo iftiin dabiici ah oo kala duwan).
