Model No.: 154021S0-LCM
Jenis bayaran: T/T
TFT bermaksud "transistor filem nipis." LCD bermaksud "paparan kristal cecair." Kedua-dua istilah tersebut merujuk kepada paparan panel rata, atau layar, monitor komputer atau televisyen. Paparan TFT dibuat menggunakan kepingan transistor yang besar, masing-masing dikendalikan secara bebas. Skrin TFT adalah skrin "matriks aktif" di mana setiap piksel paparan diterangi secara individu. Paparan TFT lebih tajam dan lebih terang daripada paparan LCD biasa. Ia menyegarkan lebih cepat daripada paparan LCD biasa dan menunjukkan pergerakan dengan lebih lancar. Paparan TFT menggunakan lebih banyak tenaga elektrik daripada skrin LCD biasa, jadi ia bukan sahaja lebih mahal harganya, tetapi juga lebih mahal untuk dikendalikan.

Catatan 1: Definisi Nisbah Kontras (CR):
Nisbah kontras dapat dikira dengan ungkapan berikut.
Nisbah Kontras (CR) = L63 / L0
L63: Pencahayaan tahap kelabu 63
L0: Pencahayaan tahap kelabu 0
CR = CR (10)
CR (X) sesuai dengan Nisbah Kontras pada titik X pada Gambar dalam Catatan 5.
Catatan 2: Definisi Masa Respons (TR, TF):
"Sudut Pandang" di atas adalah kedudukan pengukuran dengan Nisbah Kontras Terbesar; bukan untuk kebaikan
kualiti gambar. Lihat Arah untuk kualiti gambar yang baik adalah 6 Jam. Pembuat modul boleh meningkat
“Viewing Angle” dengan menerapkan Wide View Film.
Catatan 4: Penyediaan Pengukuran:
Modul LCD harus distabilkan pada suhu tertentu selama 20 minit untuk mengelakkan tiba-tiba
perubahan suhu semasa mengukur. Untuk menstabilkan pencahayaan, pengukuran
hendaklah dilaksanakan setelah menyalakan Lampu Latar selama 20 minit di bilik tanpa angin.
