ما الفرق بين تلفزيون LCD vs LED؟

ما الفرق بين تلفزيون LCD vs LED؟

تلفزيون LED هو بالأصل تلفزيون LCD لكنه نسخة محدثة منه ، أي أنهما يشتركان بنفس مبدأ العمل القائم على الاستفادة من تقنية عرض الكريستال السائل Liquid Crystal Display والتي يتم اختصارها بـ LCD .

حيث يكون هناك في التلفازين طبقتان من الزجاج تحوي إحداهما الكريستال السائل ، وهذا الكريستال يتحكم بمرور الضوء من عدمه لخلق الصورة المطلوبة على الشاشة.

والفرق المهم بينهما هو نظام الإضاءة الخلفي في داخل كل منهما ، بحيث أن تلفزيون LED يستخدم ديودات لانتاج الضوء في حين أن تلفزيون LCD يستخدم لمبات الفلوروسنت وهو ما يعطي تلفزيون LED انطباعاً لدى الناس بأن الصورة أوضح.
