Shaashadaha talefanka gacanta, oo sidoo kale loo yaqaano shaashadaha, ayaa loo isticmaalaa in lagu muujiyo sawirro iyo midabyo.Baaxadda shaashada waxa loo cabbiraa gees ahaan, badiyaa inch, oo waxa loola jeedaa dhererka gees-beelka ee shaashadda.Alaabta shaashadda Iyada oo si tartiib tartiib ah caan u ah shaashadda midabka taleefanka gacanta, shayga shaashadda taleefanka gacanta ayaa noqonaya mid aad iyo aad muhiim u ah.
Shaashado midab leh oo telefoonnada gacanta ah way kala duwan yihiin sababtoo ah tayada LCD ee kala duwan iyo cilmi-baarista iyo farsamada horumarinta.Waxaa jira qiyaas ahaan TFT, TFD, UFB, STN iyo OLED.Guud ahaan, midabada badan ee aad soo bandhigi karto, sawirka aad u adag, iyo lakabyada hodanka ah.
Qalabka shaashadda
Iyada oo si tartiib tartiib ah loo caan baxay shaashadda midabka taleefanka gacanta, walxaha shaashadda taleefanka gacanta ayaa noqonaya mid aad iyo aad muhiim u ah.Shaashado midab leh oo telefoonnada gacanta ah way kala duwan yihiin sababtoo ah tayada LCD ee kala duwan iyo cilmi-baarista iyo farsamada horumarinta.Waxaa jira qiyaas ahaan TFT, TFD, UFB, STN iyo OLED.Guud ahaan, midabada badan ee aad soo bandhigi karto, sawirka aad u adag, iyo lakabyada hodanka ah.
Marka laga soo tago qaybahan, LCDs-yada kale waxaa laga heli karaa taleefannada gacanta qaarkood, sida Jaban's SHARP GF screen iyo CG(continuous crystalline silicon) LCD.GF waa hagaajinta STN, taas oo wanaajin karta dhalaalka LCD, halka CG uu yahay mid sax ah oo sarreeya oo LCD ah, kaas oo gaari kara xallinta QVGA(240×320) pixels.
Laab shaashadda TFT
TFT (Filim khafiif ah oo saameyn ku leh goobta Transistor) waa nooc ka mid ah muraayadda dareeraha dareeraha ah ee firfircoon (LCD).Waxay "si firfircoon" u xakameyn kartaa pixels shakhsi ahaaneed ee shaashadda, taas oo si weyn u wanaajin karta wakhtiga falcelinta.Guud ahaan, wakhtiga falcelinta TFT waa mid aad u degdeg badan, qiyaastii 80 millise seconds, xagasha muuqaalkuna waa weyn tahay, guud ahaan waxay gaari kartaa 130 darajo, inta badan waxaa loo isticmaalaa alaabada ugu sareysa.Waxa loo yaqaan transistor-ka saamaynta filimka khafiifka ah macnaheedu waa in dhibic kasta oo LCD ah oo ku taal LCD-ka uu wado transistor-ka filimka ee dhabarka ku dhex jira.Sidaas ayaa lagu gaari karaa xawaare sare, dhalaal sare, macluumaadka shaashadda kala duwanaanshaha sare.TFT waxaa iska leh muraayadda dareeraha dareeraha ee matrixka firfircoon, kaas oo ay wado "matrixka firfircoon" ee tignoolajiyada.Habka ayaa ah in la isticmaalo koronto-yaqaanka transistor-ka ee ay samaysay tignoolajiyada filimada khafiifka ah, oo isticmaal habka iskaanka si aad “si firfircoon ugu jiiddo” si loo xakameeyo furitaanka iyo furitaanka barta bandhig kasta.Marka isha iftiinku iftiimiso, waxay marka hore kor u iftiimaysaa iyada oo loo marayo polarizer-ka hoose oo uu iftiimiyo iyadoo la kaashanayo molecules crystal dareeraha ah.Ujeedada bandhigga waxaa lagu gaaraa hadh iyo gudbinta iftiinka.
Tft-lcd muraayadda dareeraha ah waa filim khafiif ah oo transistor ah nooca dareeraha dareeraha ah, oo sidoo kale loo yaqaan "midabka dhabta ah" (TFT).crystal dareere TFT waxaa la siiyaa daaran semiconductor ah pixel kasta, pixel kasta waxaa si toos ah loo maamuli karaa by garaaca garaaca wadnaha, sidaa darteed noode kasta waa xad madax banaan, iyo in la xakameeyo karaa si joogto ah, ma aha oo kaliya hagaajinaysaa xawaaraha falcelinta ee shaashadda bandhigay, laakiin sidoo kale awood si sax ah u xakamee heerka midabka bandhigga, markaa midabka TFT dareeraha ah waa run badan.Muujinta dareeraha TFT ee dareeraha ah waxaa lagu gartaa dhalaal wanaagsan, isbarbardhig sare, dareen xoog leh oo lakabka ah, midab dhalaalaya, laakiin sidoo kale waxaa jira cillado isticmaalka koronto oo aad u sarreeya iyo qiimaha.Tignoolajiyada dareeraha ah ee TFT ayaa xoojisay horumarinta shaashadda midabka taleefanka gacanta.Qaar badan oo ka mid ah jiilka cusub ee muraayadda midabka teleefannada gacanta waxay taageeraan muraayadda midabka 65536, qaarna xitaa waxay taageeraan muraayadda midabka 160,000.Waqtigaan, faa'iidada isbarbardhigga sare iyo midabka hodanka ah ee TFT waa mid aad muhiim u ah.
