LED backlight technology Character LCD Modules classification and comparison

LED backlight technology in the field of LCD TV three ways: direct three primary colors RGB-LED light source, the direct type white LED light source and side-in white LED light source. Direct type RGB-LED light source technology in the integrated display advantages absolute first, but the price cost is the highest, does not have the market penetration possible. LED TV on the market in general is the use of the direct type white LED light source and side-in white LED light source products. Samsung, SONY is side-in white LED technology, Sharp, Hisense using the direct type white LED technology.128x32 oled display
Direct type: emphasis on quality performance
Direct type LED technology companies believe that the advantages of direct type LED technology on the screen regulation excellent side LED technology and the side LED TV prices were inflated. Compared in two ways, 'straight down' the performance of the quality more perfect. "55-inch LED TV, for example, the direct type product will be more than 3,000 LED lamps evenly distributed on the back of the panel, so that the backlight can be uniform to convey to the entire screen, more lifelike picture detail. Side-in is at the border of the panel is installed more than 400 LED lights illuminate the light source from the side. Although this can minimize the thickness, but a decrease of nearly 7 times the number of LED lights, so easy to make the screen brightness reduced to the form of an "X" (ie brighter than a central location around).
In addition, the use of a direct type LED TVs also the LED backlight is divided into several cells, when displaying black, directly off the corresponding LED light region, it is possible to exhibit the perfect black. Therefore, the direct type LED technology enterprises believe that the direct type LED backlight can be more accurately render the image, and show excellent color and chiaroscuro effects.
Side-in: emphasis on ultra-thin energy-saving leading
"Compared to the direct type backlight technology, side-backlight technology enterprise overall system design and integration capabilities require higher costs from the manufacturing point of view, the use of side-in white LED technology to consider the whole (host The power supply circuit, screen power and cooling) the need for light and thin, often resulting in a wide range of cost increases, so the whole cost is higher than the direct type white LED products. "Samsung TV technician for artificially high prices given such an explanation.
Slimmer volume to become the biggest bright spot in the side LED TV. According to the report, the market side LED TV thinnest thickness of only 2.99cm, and the direct type LED thinnest to 5.5cm thick.16x2 lcd
"Light" in the end is not important? Appliance industry experts said that consumers care more about the characteristics of electronic products "thin", because it is evident that the improvement of product quality is the ultimate visual expression of a brand and corporate research and development capabilities and manufacturing technology, every inch of the appearance of the product decreases means that the improvement in technology. In addition, the side LED TV is relatively more energy efficient. 52-inch LED TV, for example, the the side LED boot power consumption is only 186.5W direct type LED power-on-power up to 304W.
