1. Menene LED, LCD?
LED yana tsaye don Haske-Emitting Diode, na'urar semiconductor da aka yi daga mahadi masu ɗauke da abubuwa kamar Gallium (Ga), Arsenic (As), Phosphorus (P), da Nitrogen (N). Lokacin da electrons suka sake haɗawa da ramuka, suna fitar da hasken da ake iya gani, wanda ke sa LEDs yayi tasiri sosai wajen canza makamashin lantarki zuwa makamashin haske. An yi amfani da LEDs sosai a cikin nuni da haske.
LCD, ko Nuni Crystal Liquid, kalma ce mai faɗi don fasahar nunin dijital. Lu'ulu'u masu ruwa da kansu ba sa fitar da haske kuma suna buƙatar hasken baya don haskaka su, kamar akwatin talla.
A sauƙaƙe, allon LCD da LED suna amfani da fasahar nuni daban-daban guda biyu. Fuskokin LCD sun ƙunshi lu'ulu'u na ruwa, yayin da allon LED ya ƙunshi diodes masu haske.
2. Bambance-bambance tsakanin LED da LCD Nuni
Bambanci 1: Hanyar Aiki
LEDs diodes masu haske ne masu fitar da haske. An rage girman beads na LED zuwa matakin micron, tare da kowane ƙaramin bead ɗin LED yana aiki azaman pixel. Allon allon yana kunshe ne kai tsaye da waɗannan beads na LED masu girma. A gefe guda, allon LCD shine ainihin nunin crystal ruwa. Babban ka'idarsa ta haɗa da haɓaka ƙwayoyin kristal na ruwa tare da wutar lantarki don samar da dige-dige, layi, da saman, tare da hasken baya, don samar da hoto.
Bambanci 2: Haske
Gudun amsawar nau'in nunin LED guda ɗaya yana da sauri sau 1,000 fiye da na LCD. Wannan yana ba da nunin LED mai fa'ida mai mahimmanci a cikin haske, yana sa su bayyane a sarari ko da a cikin haske mai haske. Duk da haka, mafi girma haske ba ko da yaushe wani amfani; yayin da mafi girman haske ya fi kyau don kallo mai nisa, yana iya zama mai haske don kallon kusa. Fuskokin LCD suna fitar da haske ta hanyar karkatar da haske, suna sa haske ya yi laushi da ƙarancin damuwa akan idanu, amma yana da wahala a gani cikin haske mai haske. Saboda haka, don nuni mai nisa, LED fuska sun fi dacewa, yayin da allon LCD ya fi kyau don kallon kusa.
Bambanci 3: Nuni Launi
Dangane da ingancin launi, allon LCD yana da mafi kyawun aikin launi da aukaka, mafi kyawun hoto, musamman a ma'anar launin toka.
Bambanci 4: Amfani da Wuta
Matsakaicin amfani da wutar lantarki na LED zuwa LCD shine kusan 1:10. Wannan saboda LCDs suna kunna ko kashe gabaɗayan layin hasken baya; da bambanci, LEDs na iya haskaka kawai takamaiman pixels akan allon, yana sa su zama mafi ƙarfin kuzari.
Bambanci na 5: Bambanci
Godiya ga yanayin haskaka kai na LEDs, suna ba da mafi kyawun bambanci idan aka kwatanta da LCDs. Kasancewar hasken baya a LCDs yana da wahala a cimma baƙar fata na gaskiya.
Bambanci 6: Wartsake farashin
Yawan wartsakewar allo na LED ya fi girma saboda yana amsa sauri kuma yana kunna bidiyo cikin sauƙi, yayin da allon LCD na iya ja saboda jinkirin amsawa.
Bambanci 7: Duban kusurwa
LED allon yana da faɗin kusurwar kallo, saboda tushen hasken ya fi daidaituwa, komai daga kowane kusurwa, ingancin hoton yana da kyau sosai, allon LCD a cikin babban kusurwa, ingancin hoton zai lalace.
Bambanci 8: Tsawon Rayuwa
Rayuwar allo ta LED ya fi tsayi, saboda diodes masu fitar da haske suna da dorewa kuma ba su da sauƙin tsufa, yayin da tsarin hasken allo na LCD da kayan kristal na ruwa a hankali za su ƙasƙanta kan lokaci.
3. Wanne ya fi kyau, LED ko LCD?
LCDs suna amfani da kayan inorganic, waɗanda suke tsufa sannu a hankali kuma suna da tsawon rayuwa. LEDs, a daya bangaren, suna amfani da kwayoyin halitta, don haka tsawon rayuwarsu ya yi guntu fiye da na LCD.
Sabili da haka, allon LCD, wanda ya ƙunshi lu'ulu'u na ruwa, suna da tsawon rayuwa amma suna cin ƙarin ƙarfi saboda duk-on / kashe baya. Fuskokin LED, waɗanda suka haɗa da diodes masu fitar da haske, suna da ɗan gajeren rayuwa, amma kowane pixel tushen haske ne, yana rage yawan amfani da wutar lantarki yayin amfani.
