6 cabirrada farsamada ee laxiriira ee ka mid ah guddiga LCD

1. Aagga waxqabadka (aA)

Meelaha kala duwan ee ah LCD Gudiga soo bandhigi karaa.

2. DOT garoonka

Waxaan inta badan weydiisannaa sida ay u weyn tahay qoysaska DOT ee ka mid ah LCD-ga ee LCD, laakiin dadka intooda badani aysan aqoon sida qiimahan loo helo. Hadda aan aragno sida loo heysto. Tusaale ahaan, caadi ahaan 14 - Inch LCD waxay leedahay aagag daawashada oo ah 285.7 mm × 214.3.3 mm, sidaa darteed pixels-ka muuqaalka ah / 1024 mm / 0.249 mm (ama 214.3 mm / 768. 0.279 mm).

3. Shahaadada midabka

Qaybta muhiimka ah ee guddiga LCD waa, dabcan, muujinta midabka. Waxaan ognahay in midab kasta oo dabiiciga ah uu ka kooban yahay saddex midab oo aasaasi ah: casaan, casaan, cagaar iyo buluug. Tusaale ahaan, golaha LCD wuxuu ka kooban yahay 1024 × 768 pixels, oo midab kasta oo pixel ah oo shaqsi ah ayaa lagu xakameeyaa saddex midab oo aasaasi ah oo casaan ah, cagaar iyo buluug (r, g, b). Inta badan guddiyada LCD ee ay soo saareen soosaarayaasha LCD waxay leeyihiin 6 midab (r, g, t) midab kasta oo aasaasi ah (R), b), waa 644 × 64 = 262,144 midabbo. Waxa kale oo jira soosaarayaal badan oo LCD ah oo adeegsanaya FRC (xakamaynta heerka) tikniyoolajiyad si loo barbardhigo si buuxda Markaa, pixel kasta oo shaqsiyeed kasta wuxuu leeyahay ilaa 256 × 256 × 2566 = 16,777,216 midabbo.

4.Constrampe

Qiimaha isbarbardhiga ayaa ah saamiga qeexaya qiimaha ugu badan ee iftiinka (dhammaan caddaan) oo loo qaybiyay qiimaha ugu hooseeya ee iftiinka (oo dhan madow). Alaabada sida kontaroolada ICS, SED ee waxsoosaarka LCD ayaa laxiriira kansarka guddiga. Iskucelceliska adeegsadaha, saamiga isbarbar dhigga ah ee 350: 1 ayaa ku filan, laakiin ku jirta garoonka ganacsiga ganacsiga ama warshadaha, isbarbardhigga noocan ah kuma filna. Kaliya Sare - Dhamaadka LCD guddiga LCD wuxuu gaari karaa shahaadadaas oo kale. Tan iyo markii la taaban karo uu adag yahay in si sax ah loo cabbiro aaladda, wali waa lagama maarmaan in la eego naftaada.

5. Iftiin

Iftiiminta ugu badan ee gudiga LCD waxaa badanaa lagu go'aamiyaa iftiinka dambe. Qiimaha iftiinka ee macaamilka LCD Gudiga guud ahaan inta u dhaxaysa 200 iyo 250 cd / m2. Iftiiminta ee loo yaqaan 'LCD' ee ku yaal meelaha ganacsiga iyo warshadaha waxay u dhexeeyaan 450 illaa 5000 cd / m2. LCD waa walax u dhexeeya cunsur iyo dareere, taas oo lafteedu aysan soo saari karin, oo ay u baahan tahay ilo dheeri ah oo dheeri ah. Sidaa darteed, tirada laambadaha ama guluusku waxay la xiriiraan iftiinka guddiga LCD.

6. xagal daawanaya

Guud ahaan, xagasha aragtida LCD Gudiga waa summad iyo midig, halka dusha sare iyo hoose aysan ahayn daruuri. Tusaale ahaan, markii shilka iftiinka iftiinka uu ka gudbayo saxanka 'plarizing plate', dareeraha dareeraha ah, iyo filimka isku-dhafka ah, nalka wax soo saarka, taasi waa, in inta badan iftiinka shaashadda ka soo baxa ayaa leh jihada toosan.

Guud ahaan, xaglaha sare iyo hooseba waxay ka yar yihiin ama u dhigma xaglaha bidix iyo midig. Haddii xagasha aragtida ay tahay 80 digrii bidix bidix iyo midig, waxay la micno tahay in sawirka shaashadda si cad loo arki karo markii laga bilaabayo booska 80 digrii oo ka mid ah shaashadda. Si kastaba ha noqotee, sababtuna tahay kala duwanaanshaha kala duwan ee aadanaha, haddii aadan ku dhex istaagin xagasha aragtida ugu wanaagsan, waxaa jiri doona khaladaad midabka iyo iftiinka la arko. Soo-saareyaasha qaar ayaa soo saaray kala duwan oo tikniyoolajiyad ballaaran oo xagal ah si loo wanaajiyo astaamaha xagal xagal eeQulqulka dareeraha dareeraha ah, sida IPS (oo ku jirta diyaarinta diyaaradda), MVA (MVA), isku-dhafan toosan), iyo filim TN +. Teknolojiyadan waxay kordhin karaan xagasha aragtida LCD Gudiga ilaa 160 digrii ama ka badan.
