What is the difference between TV screen LCD and LED

TV is a necessary appliance for people to watch exciting programs at home, its history process is relatively long, after a series of technical changes. Development so far, the mainstream of the market in the form of television mainly lcd and led two, I think some owners in the purchase, often hear the guide to introduce the two forms, although listening to more, but for the specific difference is not very well understood. Here I will bring you what is the difference between LCD TV and led, to popularize the knowledge.

lcd display manufacturers, specializing in the development and production of LCD monitors. High-quality products, low power consumption, fast delivery, and reasonable price.

led as the backlight can make the display thinner and lighter, and the color rendering will be better. lcd TVs use cold cathode fluorescent tubes, which are also considered more destructive to the environment because they contain mercury. LED LCD TVs, on the other hand, use light-emitting diodes, which do not have mercury problems. However, for the end consumer, even if the use of mercury-containing traditional LCD TV, in the actual use of the process, will not cause very direct damage to the environment.

Second, the difference between the backlight effect, the difference between the two exists not only in terms of display and safety, the difference between the backlight effect is also very obvious. In today's familiar LCD technology, it is not luminous itself, the need to use backlighting to illuminate. This lighting technology is further divided into lcd and led. led technology is more advanced than lcd, so the overall visual effect of led TVs is better, and of course the price will be higher.

Third, the difference between led and lcd TV working principle, the working principle is the fundamental reason to decide the final effect of the appliance, which is the reason why many appliances in the manufacturing process to pay attention to the working principle. Which lcd is liquid crystal display, led is light-emitting diode. The current home TV, labeled led is the use of light-emitting diodes instead of fluorescent tubes as the backlight of the LCD panel, due to the omission of the boost circuit, more power-efficient, but in fact this type of TV still use lcd display. lcd is the unit that can achieve reality, the early years of OLED is the cell phone display, but the current practicalization of this technology there is a gap.
