LED LCD TV features slim
The thickness of traditional LCD TVs is usually about 10cm. LED backlighting is more common on laptops. It is used on TVs to make a thin leap in body thickness.
energy saving
CCFL cold cathode fluorescent lamps used in traditional LCD TVs contain mercury that is harmful to the human body. Although manufacturers are looking for ways to reduce the amount of mercury in fluorescent tubes, completely mercury-free fluorescent tubes introduce new technical problems. The LED backlight does not contain mercury, in line with the green fashion. LED backlights are also very power-efficient. The internal driving voltage of LED is far lower than that of CCFL, and the power consumption and safety are better than that of CCFL.
long life
The rated service life of different CCFLs (semi-bright) is between 8,000 and 100,000 hours. The CCFL backlight with improved design for enhanced performance will also have a lower lifetime. The LED backlight can reach about two times the CCFL. Therefore, LED backlights typically have a longer life than CCFLs.
Wide color gamut
In fact, it is quality of picture quality. According to the different color of light, LED can be divided into white LED backlight source and RGB-LED backlight source. The advantages of white LED technology are mainly low power consumption, while the advantage of RGB-LED backlight source is excellent color performance. The RGB-LED backlight source can achieve a wide color gamut range that can not be achieved by a conventional CCFL light source through LED devices that can emit high-purity red, green, and blue light. At present, the mainstream RGB-LED backlight source can already reach 105% of the NTSC color gamut range. The more powerful LED devices can achieve more than 120% NTSC color gamut.
For LCD TVs, its unique imaging principle of controlling the external light using the alignment changes of the liquid crystal molecules determines that the LCD panel is the key to influencing the display effect. Therefore, when choosing a TV, the key indicator is whether or not this product is a high-quality panel. LED can't afford absolute effect!
Hard screen and soft screen
LCD TVs, which account for more than 70% of the flat-panel TV market, have apparently become the mainstream of the market! To choose a good LCD TV, a good LCD screen is very important! So, how can we buy a cost-effective color TV, it is currently Most consumers are very concerned about the issue. Today, we understand the difference between hard screens and soft screens. Is it really better to use hard screens promoted by shopping guides on the market? Let consumers make their own decisions.
