What is the difference between LED entry and LED array? Which is better?
The difference between LED straight down and side entryAt present, the market has LGD, IPS hard screen as the representative of the direct down LED backlight (dot matrix), Samsung and SONY manufacturers widely used side - entry LED backlight. Simple, direct type LED light source is in dot matrix form, the panel is evenly covered on the back; side backlight is on the panel frame was installed around the LED light source, and the light guide plate to make the light projecting from the side of the form.
Direct type LED light source number in several times higher than the side. So the cost is higher, the direct type partition can realize intelligent dynamic backlight control technology, which can realize the lateral body slim (three cm), direct type usually body thickness is above three cm to five cm or more thick. This is the contradiction between the quality and the ultra-thin, want to slim, you have to sacrifice the quality of the picture, but for average users, about four or five centimeters of thickness is also very thin.
Thanks to the light projection more accurate, IPS hard screen as the representative of the direct type backlight can be adjusted through the dynamic light regional, based on enhancing dark gray scale expression, enhance the overall image layering and details; and edge LED backlight backlight can use compressed space, achieve to effectively reduce the thickness of the screen. But the simple measure of LCD TV consumer's core interests - quality, direct type LED backlight to IPS hard screen represented more advantages, coupled with the thickness of only LGD launched straight type LED backlight system 2.4cm in September 2009. The dilemma between the quality and appearance of the ultra-thin has also been effectively resolved. Therefore, from the current level of technical application, the direct LED backlight screen represented by LGD is more competitive in the market.
