Direct LED में उच्च चमक और बेहतर काले और बैकलाइट की एकरूपता प्रदान करता है, लेकिन प्रदर्शित करता है कि इस तकनीक का उपयोग आमतौर पर थोक होता है और अधिक Edge-Lit vs. Direct-Lit. Wie bei Full-Array-Fernsehern verwenden Direct Lit-Fernseher mehrere Reihen von LEDs, die hinter der gesamten Oberfläche des Bildschirms platziert sind. Direct Lit-Fernseher verwenden jedoch kein lokales Dimmen, was ein Schlüsselfaktor dafür ist, wie Full-Array-Fernseher tiefe, gleichmäßige Schwarztöne erzeugen
Direct-lit displays have several rows of LEDs behind the screen that operate as one. Without any local dimming, direct-lit displays produce generally lower quality images with a lot of gray tones instead of true black. Another backlight configuration is edge-lit displays, which do allow different areas to be dimmed.
Если дома есть питомцы, то Edge LED – явно не ваш выбор. Подсветка Direct LED, в отличие от своей соперницы, наоборот, утолщает габариты экрана. В некоторых ситуациях это может также быть негативом
There are two types of backlights: 1. CCFL (cold cathode fluorescent lamps) which was the first type of LCD backlight and it is quickly being replaced by the 2nd type of backlight because it is simply better. 2. LED (light-emitting diodes) is the newer type of LCD backlight which has become predominantly the primary LCD backlight source in LCD
LED vs OLED TVs. LED-type TVs have a liquid crystal panel that forms the picture, but this panel does not create any light itself. That is the job of LEDs placed behind the panel. The first LED TVs used what was called “Edge-Lit” with LED’s surrounding all four sides, just the left and right side or top and bottom, or even just the bottom.
73.524. Οι direct LED έχουν LEDs διασκορπισμένα πίσω απ' όλη την επιφάνεια του panel, οι edge LED μόνο γύρω-γύρω. Υπάρχει διαφορά στην ομοιογένεια φωτεινότητας και στη δυνατότητα local dimming (τοπική μείωση
알려진 바와 같이 LCD 픽셀은 빛을 방출하지 않으며 백라이트가 필요합니다. LED 백라이트는 현대 TV에서 가장 많이 사용됩니다. 다이렉트 LED와 엣지 LED로 나뉩니다. Direct LED는 매트릭스 뒤의 LED를 표면 전체에 사용하고 Edge LED는 측면 둘레를 따라 LED를 사용합니다. ZdwydG6.
