Direct type and side-in type refer to the two main methods of applying LED light source technology in the field of LCD TVs. At present, most of the LCD TVs on the market use these two backlight sources. Why LCD TVs adopt LED light source technology, but they have chosen different backlighting methods. What are their common characteristics and personality? The following small series to make a simple answer for everyone. CCFL backlight TV LED backlight refers to the use of LED light-emitting diodes to generate light as a backlight for LCD TV screens. Compared with traditional CCFL backlights, the advantages are obvious. First, it offers a wide range of brightness control and strong applicability. Second, the LED's light is planar and has a good balance of brightness. Third, the LED consumes less energy and has a long service life. Low cost; Fourth, it has a wider color gamut and can produce high-quality color effects. Therefore, the LED backlight technology has rapidly replaced the traditional CCFL technology. With the deepening of the application of LED backlight technology, people name the two main methods as direct-down and side-in, depending on the difference in the position of the LED backlight source. Direct type RGB panel Direct-type LED backlight technology pays attention to the effect of the screen. It evenly distributes the LED lights on the back of the panel, so that the screen can evenly receive light. Even the edges of the screen can be clearly displayed. The screen is more delicate and natural. At the same time support the dynamic control of backlight, regional control can be maintained to maintain the high quality of the screen. However, it means that it will have to install more LED lights, and it will cause troubles in the arrangement of routes and installation of other components, and it will require huge cost investment, which will make the retail price high and consumers are not easy to accept. Therefore, people who are positioned to enjoy high image quality are the road to success for such products. At present, Samsung and LG are the representatives of companies that use direct backlight technology. Direct backlight LCD TV The advantage of the edge-in LED backlight technology is that the body of the LCD TV will be thinner. Compared with the direct type, the side-entry type only needs to install a few LED lights on the side, which greatly reduces the need to configure the object, the screen thickness is greatly reduced, to create a very thin body, in line with the current fashion life Style, and consume relatively less energy, the price is more civilian. Sharp and Sony are using a side-by-side company representative. Side-entry backlight LCD TV According to the test of the relevant testing department, LCD TVs with direct type and side-in type are adopted. By the naked eye, people cannot judge whether there is a big difference in the picture quality between the two. Therefore, Xiaobian believes that LED technology will have a longer period of time. The development, in the purchase of LCD TVs, to do what it takes, do not have to deliberately choose a certain kind of LED backlight LCD TV, feel right on the line.
