Chii chinonzi liquid crystal display (LCD)? Tsanangudzo yezviratidziro zveLCD uye kuti akasiyana sei neanoratidza LED
Pfupi yeLCD, liquid crystal display itete, flat display device yakatsiva yekare CRT monitor. Iyo LCD skrini inopa zvirinani mufananidzo wemhando uye tsigiro yezvisarudzo zvakakura.
Kazhinji, LCD inoreva rudzi rwe skrini vanoshandisa LCD tekinoroji, asiwo flat-panel inoratidza seaya anowanikwa mumalaptop makomputa, makarukureta, makamera edhijitari, wachi dzemadhijitari, uye zvimwe zvakafanana.
Panewo murairo weFTP unoshandisa mavara "LCD". Kana zviri izvo zvauri kutsvaga, saka unogona Verenga zvakawanda nezvazvo pawebhusaiti yeMicrosoft , asi hazvinei nemakomputa kana zviratidziro zveTV.
LCD skrini inoshanda sei?
Sezvinoratidzwa nekristaro mvura MaLCD skrini anoshandisa makristasi emvura kuvhura uye kudzima pixels kuratidza rumwe ruvara. Makristasi emvura akafanana nemusanganiswa pakati pechinhu chakasimba uye chemvura, umo magetsi emagetsi anogona kushandiswa kushandura mamiriro avo kuitira kuti mamwe maitiro aitike.
Aya makristasi emvura anogona kufungidzirwa sevhavha yehwindo. Kana shutter yakazaruka, chiedza chinogona kupinda mumba nyore nyore. NeLCD zvidzitiro, kana makristasi anoenderana neimwe nzira, haatenderi kuti chiedza chipfuure.
Ndiyo kumashure kweLCD iyo ine basa rekuvhenekera mwenje pahwindo. Pamberi pechiedza pane chidzitiro chakagadzirwa nemapikseli ane ruvara rutsvuku, bhuruu kana girini. Iwo makristasi emvura ane basa rekubatidza kana kudzima sefa kuitira kuti vaone rumwe ruvara kana kuchengetedza iyo dema pixel.
Izvi zvinoreva kuti maLCD monitors anoshanda nekuvhara mwenje unoburitswa kubva kumashure kwechidzitiro pane kugadzira iwo mwenje wega semabatirwo anoita CRT. Izvi zvinobvumira LCD monitors uye maTV kushandisa simba shoma pane CRT.
LCD vs LED: Ndeupi musiyano?
LED inomirira Light emitting diode . Kunyangwe iine zita rakasiyana neRatidza mvura yekristaro , kunze kwekuti hachisi chimwe chinhu chakasiyana zvachose, asi chaizvoizvo chakarurama Type Yakasiyana-siyana yeLCD skrini.
Musiyano mukuru pakati peLCD uye LED skrini ndeyekuti iyo backlight inopiwa sei. Iyo backlight inoratidza nzira yekubatidza kana kudzima skrini, izvo zvakakosha pakupa mufananidzo wakanaka, kunyanya pakati pezvikamu zvitema uye zvine mavara zvechidzitiro.
Yenguva dzose LCD skrini inoshandisa inotonhora cathode fluorescent rambi (CCFL) yezvinangwa zvekudzosera kumashure, nepo ma LED skrini anoshandisa zvinobudirira uye madiki mafotodiode (LED). Musiyano ndewekuti CCFL backlit LCD skrini haigone kugara ichivharira kunze zvese Vatema, mune iyo mamiriro ezvinhu senge dema-pa-chena chiitiko mu-ultra-black firimu inogona kusaoneka zvachose, nepo LED-backlit LCDs inogona kusarudza vatema kune yakadzika mutsauko.
Kana iwe uine nguva yakaoma kunzwisisa izvi, ingofunga nezverima bhaisikopo chiitiko semuenzaniso. Muchiitiko ichi mune kamuri dema chairo rine gonhi rakavharwa richipinza chiedza mukati nepaburi rezasi. Chidzitiro cheLCD-backlit LCD chinogona kuibvisa zviri nani pane kudzoreredza CCFL skrini nekuti yekutanga inogona kungoridza ruvara kune chikamu chakatenderedza gonhi, ichibvumira iyo yese skrini kuti irambe yakasviba zvechokwadi.
Haisi yega yega skrini ye LED inokwanisa kudzima skrini munharaunda, sezvandangoverenga. Kazhinji anongozara-akazara maTV (akatarisana neaya anovhenekera) anotsigira dimming yemuno.
Rumwe ruzivo paLCD
Zvakakosha kungwarira nguva Kuchenesa LCD skrini , ingave maTV, mafoni, mamonitor emakombuta, nezvimwe.
Kusiyana neCRT monitors uye terevhizheni, maLCD monitors haana refresh rate . Ungada kuchinja Refresh rate setting Monitor pane CRT yekutarisa kana kunetsa kweziso iri nyaya, asi hazvifanirwe pane nyowani LCD monitors.
Mazhinji eLCD macomputer monitors ane tambo yekubatanidza HDMI و DVI. Vamwe vachiri kutsigira maCables VGA , asi izvi hazvishamisi. Kana vhidhiyo kadhi kukombiyuta yako chete tsigira yekare VGA yekubatanidza, tarisa kaviri LCD yako yakabatana nayo. Ungangoda kutenga VGA kuenda kuHDMI adapta kana VGA kuenda kuDVI adapta kuitira kuti migumo yese ishandiswe pane yega yega.
Kana pasina chinoonekwa pakombuta yako, unogona kuita matanho ari mugwara redu rekugadzirisa dambudziko Maitiro ekuyedza komputa skrini isingashande kuziva chikonzero.
