Di LCD TV atau "transmissive" terpajang, seorang sumber ringan bersinar
Lewat sejuri kristal cair untuk memperlihatkan
Citra. Setelah pantat juri difusi putih LCD mengalihkan dan
Menyebar lampu secara merata untuk memberikan tamsilan yang lebih seragam
Daripada kebanyakan teknologi bersaing.
Muka LCD terdiri atas dua lapisan transparan yang
Mempolarisasikan selapisan kristal cair yang terjepit di antara.
Muka lapisan kaca dietsa dengan pola kisi-kisi di
Di dalam permukaan untuk membentuk kerangka untuk kristal cair.
Kristal cair ialah tangkai membentuk molekul yang menekuk cahaya
Di jawaban ke arus listrik; kristal begitu melurus
Bahwa tak ada lampu bisa lewat lewat. Masing-masing kristal bertindak suka
Kamera 's penutup lensa, baik cahaya menghalangi atau membolehkannya ke
Lewati. Pola kristal transparan atau gelap
Membentuk tamsilan. Teknologi sama ini sudah sekitar untuk
Sebentar, di barang seperti itu yang tak canggih pun sedigital menonton.
LCD TVs menggunakan "aktif matriks" LCD; macam yang paling maju
LCD. The pola matriks aktif berpangkalan di TFT, atau tipis
Transistor film. Yang ini adalah transistor mengganti yang sangat kecil dan
Kapasitor yang diatur di matriks di atas gelas substrate,
Mereka bertukar LCD pixels di dan dari. Di LCD TELEVISI warna,
Masing-masing warna pixel dibuat di samping tiga sub-pixels dengan merah, hijau,
Dan warna biru menyaring.
Salah satu tantangan yang paling besar bagi LCD TV pengusaha pabrik mempunyai
Meluncur ke atas pixel waktu jawaban, (bagaimana cepat
Perseorangan pixel 's warna bisa berganti dengan tidak mengabur) agar
Tamsilan mengharukan yang cepat tidak menunjukkan ketinggalan gerakan atau "ghosting".
Ini teramat kritis untuk layar lebih besar LCD TVs, atau
Bagi LCD TVs di yang banyak melihat akan menjadi HDTV, atau
DVD movies.
An important difference between LCD technology and Plasma is
that an LCD screen doesn't have a coating of phosphor dots;
LCD TVs color is created through the use of filters. This
keeps image burn-in from being a problem--- which is good
news in-particular for people who might use a video gaming
system or PC on their TV. Another benefit of owning an LCD
TV is the energy efficiency of this technology. LCD TVs
typically consume 60% less power than comparably sized
tube-type, direct-view TVs.
In most ways that really matter there isn't much difference
between LCD TVs and Plasma TVs. Both of these highly popular
types of flat panel TVs are thin enough to be placed virtually
anywhere, and both produce images that are startlingly clear,
sharp, and bright. The most notable difference is screen size.
The majority of LCD TVs have a screen size measuring 30 inches
and smaller. Plasma TVs are, for the most part, uninhibited
by measurement restrictions.
Basically, LCD and Plasma TVs are different approaches to the
same result because the both create superior images using
radically different technology.
