When consumers don't understand the product, they are easily guided by advertisements and shopping guides, and fall into the wrong side of the purchase. Therefore, when purchasing high-tech products such as electronics and home appliances, smart consumers tend to do homework in advance to understand the various parameters of related products. However, does this mean that when consumers understand the product, they can make a correct judgment? In fact, most of the relevant product knowledge we have learned is jointly created by the manufacturers and even the industry for commercial interests. As a non-professional consumer, in the face of many nouns, concepts, and data, it is easy to fall into another misunderstanding of the purchase - the misunderstanding of ideas.
With the increasing popularity of LCD TVs in recent years, as a must-have appliance in traditional homes, whether buying new home appliances or upgrading old ones, consumers' enthusiasm for buying TV has always increased. For the beautiful lies of LCD TV manufacturers, you know how much.
NO1. About LCD and LED
The TVs on the market mainly include CRT TVs, that is, traditional CRT TVs. LCD TVs are now mainstream LCD TVs sold in the market, and PDP TVs are plasma TVs. At present, the so-called "LED TV" on the market only replaces the original CCFL backlight with LED backlight, and still uses LCD panel and passive illumination. In the strict sense, it should be called "LED backlight LCD TV". LCD TVs with LED light sources are superior to LCD TVs with traditional light sources in terms of size and energy consumption. However, the use of passive lighting LCD panels destined to high-priced LED TVs must retain the inherent weakness of LCD TVs: tailing phenomenon, subtle light leakage, insufficient color gamut performance. There are still some manufacturers who use "LED TV" as a concept of hype, which is much higher in price than LCD TVs of the same size. In fact, traditional LCDs in foreign countries are also selling well. The market research organization DisplaySearch2010 global TV market report shows that in 2010 global LCD TV sales, LED sales accounted for only 30%. In terms of domestic sales, the Pangoo LC-42A58, which is the 2010 Taobao annual sales champion, is also a traditional LCD TV product. Perhaps in the near future, LED-backlit TV will gradually become more popular with the upstream supply situation, but consumers should still make rational choices based on individual needs.
NO2. About the ultra-wide color gamut
Following the dynamic contrast ratio, the ultra-wide color gamut has become another hot concept promoted by manufacturers in the LCD TV war. The gamut value represents the range of colors that the display can present. The larger the gamut, the richer the color of a color that can be displayed on the display screen, and the more vivid the color. As for the wide color gamut that manufacturers are sizzling, it actually means a value slightly higher than the value of the normal LCD gamut. For example, the current color gamut of the mainstream LCD is 72% of the NTSC gamut range, so as long as the gamut value is higher than 72%, the manufacturer will call it a wide color gamut. A large color gamut can only represent a wide range of colors, and does not mean that there are many colors. The color gamut LCD color display is more vivid, but some color displays, especially red and green, may appear false or supersaturated, and different brands will make their own choices. For example, LG's main IPS panel has high color reproduction brightness, and the light leakage problem and high brightness are the Achilles heel; Samsung's SPVA panel, the wide color gamut makes it bright and colorful, and the corresponding color distortion and tired eyes. It is inevitable; the MVA panels used by many domestic brands, including Pangoo Pangu, are more compromised in color performance, even being overly light by fans of the ultra-wide color gamut, but in terms of color reproduction, they are even and even. Make MVA the softest and most realistic of the eyes in the three panels. Therefore, consumers should believe their eyes when purchasing TV, instead of blindly referring to laboratory data to pursue ultra-wide color gamut.
NO3. About Japanese original panel
As the most important core component of LCD TVs, LCD panels cost 60%-70% of the total TV cost. Therefore, when consumers purchase LCD TVs, the choice of panels becomes crucial.
