เจ๊ๆ จริงๆ แล้ว LCD / LED จอคอมพิวเตอร์ หรือจะเป็น LCD / LED ทีวี มันใช้ Techonologies ไม่ได้ต่างกันมากหรอก!
ส่วน Panel ก็เป็น LCD เหมือนเดิม แต่จะต่างกันเฉพาะ Backlighting เท่านั้น LCD Monitor ที่เรียกกันทั่วไป จะใช้ Backlighting แบบ Fluorescent LED Monitor ที่เรียกกันทั่วไป จะใช้ Backlighting แบบ LED
LED-backlit LCD television or LED TV (term used by Samsung Electronics, Toshiba, Philips, LG Electronics and Vizio) is an LCD TV that uses LED backlighting.[1] LED's are used for backlighting, instead of fluorescent lights. Light-emitting diode televisions (LED TVs) are LCD television sets that use LED as back light unit (BLU). LEDs in their current form are much too large to be individual pixels on a conventional television. The use of a true LED display is therefore reserved for much larger screens in sports grounds and other commercial locations. The LEDs can come in two forms, Dynamic RGB LEDs which are positioned behind the panel, or white Edge-LEDs positioned around the rim of the screen which use a special diffusion panel to spread the light evenly behind the screen. [2] RGB Dynamic LEDs This method of backlighting allows dimming to occur locally creating specific areas of darkness on the screen. This means you see truer blacks and much higher dynamic contrast ratios. Edge-LEDs This method of backlighting allows for LED TVs to become extremely thin. The light is diffused across the screen by a special panel which produces a uniform color range across the screen.
