How to choose LED flat panel TV

As the LCD market continues to mature, LED TVs are becoming mainstream. Although the current LED LCD TV is only the difference in backlight, the picture quality performance is not small. The "new" category that this flat-panel TV field has spawned has a great potential to replace traditional LCD TVs.

LED is only ultra-thin and color

As is known to all, LEDs have a narrow luminescence spectrum and good color purity. When performing video images, LED LCD TVs are eye-catching, and even in the bright environment of the store, the details can be clearly displayed. According to the author's understanding from many aspects, this has something to do with the LED backlight itself. Due to the backlight characteristics of the LED, the color saturation of the LED TV is very high, and the color range is very wide.
Moreover, the side-lit LED LCD TV can be much thinner. This also makes LED LCD TVs more power efficient than ordinary LCD TVs. At present, Samsung, LG, Konka, Hisense and other manufacturers have introduced side-mounted LED TV products.

How to choose the screen size

Large size is the inevitable development trend of flat-panel TVs, but what size is it reasonable to buy? Buying TV is the most taboo subjective willingness, and the bigger the better. Everyone buys 42 inches, then I also buy 42 inches, otherwise I feel "out of date."

It is most reasonable to choose the size according to the size of your personal housing space. Of course, the size of the space mentioned here mainly refers to the visible distance (the distance between the human eye and the TV screen). TVs need to be watched for a long time, and the momentary make-up or awkwardness will cause visual fatigue for a long time. It will affect the health of the body for a long time.

LCD panel selection

The LCD panel can be divided into a hard screen and a soft screen according to the display technology. The soft screen mainly refers to the VA panel, and the hard screen is the well-known IPS panel.

In all aspects of performance, IPS hard screen response speed, excellent motion picture, stable picture quality, large viewing angle, cost control is better. The biggest feature of the IPS panel is that its two poles are on the same surface, unlike the other liquid crystal mode electrodes are arranged on the upper and lower sides. However, since the electrodes are on the same plane, regardless of the state in which the liquid crystal molecules are always parallel to the screen, the aperture ratio is lowered and the light transmittance is reduced, so IPS applications require more backlights on the LCD TV. To a certain extent, the power consumption is larger.

Is the LCD TV charging?

The LCD TV is different. The LCD TV is passively illuminated, and the brightness of the picture shows the light of the full back light tube. Whether it is a dark or dark scene, the backlight is always on. The power consumption of the LCD TV is a constant value, and the nominal power number is also the power number in actual use. The application of new energy-saving technologies has made LCD TVs have light-controlled devices, so LCD TVs will be more energy-efficient to some extent.

Does the LCD TV have a long service life?

It is said that LCD TVs are longer than plasma in life, which is one-sided. The two should be said separately: although the lifetime of the liquid crystal material can be said to be infinitely long, the lifetime of the liquid crystal material is not equal to the life of the liquid crystal television, and the liquid crystal panel may also appear due to damage of the liquid crystal driving tube during use. Pixel dead pixels are dead pixels and cannot be fixed. The life expectancy of a liquid crystal television, the so-called 60,000 hours, refers to the life of the backlight tube. With the current technology, the backlight tube cannot be replaced separately, and it needs to be replaced together with the replacement.
