Supplementary knowledge: How to choose an LCD TV
In addition to the tips introduced above when purchasing an LCD TV, there are other things to consider, such as interfaces, LCD panel size, resolution, etc. In short, as a consumer, you need to learn more professional knowledge, not be superstitious about the parameters in manufacturers' advertisements, focus on your own actual viewing experience, and shop around, so that you can choose a satisfactory LCD TV.
How to distinguish various types of LCD panels
For flat-panel TVs, the display screen is the most important component, accounting for approximately /3 of the cost of the entire machine. LCD screens are divided into ordinary screens, general screens and professional screens due to different technologies and processes. This kind of display screen is a special screen for LCD TVs. It has greatly improved image resolution, color, and layering. It can truly reproduce digital high-definition picture quality, and is especially suitable for receiving digital TV. LCD screens currently on the market are divided into three grades: the best quality ones are Sharp screens, but they are basically not available outside the country, followed by screens from Japanese and Korean manufacturers, such as Samsung Electronics () and. Finally, screens produced by Taiwanese manufacturers, such as Friends Dahe Chimei. At present, only these five major manufacturers have the ability to cut large-size LCD panels above inches. Choosing a panel from a large manufacturer with advanced technology will be beneficial to future use. For example, its service life and color will be better than low-end panels. The following introduces the characteristics and identification methods of several common LCD panels.
Detecting screen tailing
Human eyes have a certain reaction time when viewing dynamic images. If the response time is long, the lag of moving images will occur, which will greatly affect the image effect. If the response time is shorter, in When watching fast-moving pictures, you will not feel any traces of afterimages or delays. Picture tailing was a disadvantage of early LCD TVs. However, with the continuous improvement of technology and technology, the response time of most LCD TVs has been shortened to milliseconds, and some even reached milliseconds. Such a short response time is far faster than the human eye. Fast, the tailing phenomenon that was easily caused by fast moving images in the past almost no longer exists. However, in addition to response time, the optimization of the manufacturer's algorithm will also have a great impact on eliminating tailing and afterimage phenomena.
Nowadays, some LCD TVs have completely eliminated the tailing and afterimage phenomena through innovative technological improvements. For example, Konka Sports TV uses digital motion compensation circuitry and Dynamic 3 noise reduction technology. This technology can quickly detect TV signals in an instant, adopt different processing methods for moving areas and static areas, eliminate snow blur in moving pictures, avoid comb teeth in moving parts, ensure the proper sense of speed, and effectively eliminate smearing.
When we buy a TV, we need to look at the TV screen from multiple angles. For example, choose the angle to face the screen, then offset it by some angles, and stand at the same level as the TV screen to see if it can When inspecting the machine when you see the image, you can also ask the promoter to play some faster pictures to see whether the movements displayed on the picture are coherent and whether there is tailing in the picture.
Easily identify dead pixels and bright spots
When some friends were buying LCD TVs, they saw the picture played by the promoter was perfect, but after buying it home for a while, the bright and dark pixels were broken. Dots appear on the screen one after another, which seriously affects the picture effect. It is not that easy to go to the merchant to argue. So how can you identify whether the LCD TV has dead pixels or bright spots when buying it? There are three methods to choose from:
The easiest way is to make the screen completely black and see if it is in pure black. There are bright spots. Then make the screen completely white and see if there are any black spots. Finally, switch to red, green, and blue to check the integrity of the color points. If during the inspection you find that there are more bad pixels than the national standard, don’t buy it.
Another method is to connect the computer to the LCD TV, and then display the required picture through a solid color picture in software such as , . You can also select the desktop of the corresponding color in the computer desktop properties to detect it. This method is actually the same as the detection method when purchasing an LCD monitor.
The third method is to use disc testing, which is a home theater audio-visual test disc. The original version of this disc has Chinese subtitles, explaining in detail the complex test steps. It enters the test step when watching the disc. During the test, it is clear whether the LCD TV has dead pixels or bright spots.
, Contrast is tricky
Contrast refers to the ratio of the brightness of the brightest pixels and the darkest pixels in the screen display image. It directly affects the transparency of the image, the vividness of the color and the clarity of the image. Spend. In layman's terms, the higher the contrast, the whiter we see and the purer black we see. But when you walk into a home appliance store, you will find that the marked contrast values are all kinds of, which makes people a little headache, such as what is the effective contrast:, dynamic contrast:, the highest contrast, etc. If you think the higher the contrast, the better the product, then you are right. Manufacturer’s digital trap.
In fact, these numbers cannot reflect the contrast performance of flat-panel TVs. They are just numbers. There are indeed differences in contrast effects between different brands, series, and models, but the magnitude of the difference is the same as the one marked. The numbers are not directly related.
For the identification of TV contrast, when purchasing, you can ask the salesperson to put some discs with particularly dark scenes under normal lighting conditions, and adjust the contrast of the TV to the middle to see if the details of the picture can be clearly seen. For example, in the night scene, if you look at a black building, can you see it clearly? If the details cannot be distinguished, the contrast of this TV will not be very good because it is completely dark. Then show some particularly bright pictures, such as surfing pictures under strong direct sunlight, whether the faces of athletes and the waves are clearly layered. If the details of the picture are lost and only white flowers are seen, the contrast is not very good. Generally speaking, if the contrast is not good, the colors will be severely mutated, losing their color and luster, and the texture and details will not be visible clearly. In this regard, international brands may do better than small and medium-sized brands, high-priced LCDs do better than low-priced ones, and small sizes are better than large screens.
, Take precautions before they happen, and keep an eye on service commitments
LCD TVs are a home appliance product with a relatively high technical content, which also means that once quality problems occur, repairs are also very troublesome. When purchasing an LCD TV, consumers must ask the seller or manufacturer for detailed information about the three-guarantee product, including: the three-guarantee period for the complete machine, the three-guarantee period for major components, a specific list of major components, etc. Most manufacturers provide warranty services ranging from 3 years to 3 years, and some manufacturers even provide free door-to-door service and reduction of maintenance costs during the warranty period. These small details must be clarified before purchasing, and the operator must ensure the correct three-guarantee service. The commitment is clearly marked in text on the Three Guarantees voucher or invoice.
