The LED era is coming. The fierce technical competition among enterprises, especially panel makers, has quietly begun. Recently, the industry is paying attention to the direct-type ultra-thin LED backlight module introduced by LGDisplay. It is understood that the thickness of this product is controlled at 2.4cm, which is even thinner than the thinnest LED TV!
LED TVs are LCD TVs that use LEDs as backlights. In terms of design methods, display manufacturers generally use two methods: direct down and side light. The edge-light type LED module mounts an LED at the frame of the panel to illuminate the light source from the side. The advantage of this method is that the thickness is minimized, but the brightness of the screen is reduced in the form of "X" because the light source cannot be uniformly transmitted.
The direct way is to evenly distribute the LEDs behind the panel, and the light diverging from the source can be evenly transmitted to the entire screen. It uses Lo-calDimming (regional control) technology. When displaying black, it directly turns off the light in its corresponding LED area and can display a perfect black. Therefore, experts generally believe that the direct backlight can more accurately present the image and show excellent color and contrast between light and dark. However, the emission of LED light requires a certain amount of space. In order to reduce the thickness of the direct-lit backlight technology, it is necessary to install more LEDs more closely, to minimize the light diffusion space or separate the substrate portions such as the tuner and the power supply unit separately. Because of this, LGDisplay's direct-lit LED backlight module with thickness control up to 2.4cm is very amazing.
The industry believes that under the LGDisplay push, the direct-lit backlight technology that combines ultra-thin appearance with better image quality will be more likely to become a trend.
