Today LED-lighting for many of the revolutionary advancement in the production of television sets eventually turned into an additional feature, which is often difficult choice in favor of a device, as you need to think about the benefits of each option to take an informeddecision.
Indeed, buying a television, do not want to make a mistake in the end, buying something that actually represents the technology of yesterday, that does not make sense to use in today's realities.Fortunately, no serious difficulty in this matter is actually not, and its importance is quite exaggerated.
Advantages and disadvantages of LED itself
Each option has its own LED technology advantages, namely:
- a higher degree of efficiency.
- Ability to create televisions with a fairly thin screens.
- Complete absence of mercury in LEDs.
These advantages are considered in relation to the implementation of other technologies lighting, previously used in other types of TVs.
It is worth noting a few downsides, which are characteristic for all types of illumination format LED:
- Initially, this type of lighting does not provide improved viewing angle LCD.
- Thinner models with side illumination, may suffer from non-uniformity of illumination of the screen.
- LED-illumination can ultimately provoke unwanted local dimming pictures on the screen.
course, these shortcomings in the overwhelming majority of cases are eliminated in various models of monitors and TV sets, as the technology is continuously improving.Thus it is necessary to correctly understand that not only one lighting affects the quality of images on the TV.
High quality images that allow you to watch TV today, could appear largely due to the fact that the developers have started to use LED backlight technology.At the time, the emergence of LED-TVs could produce very real revolution in the market, because the new lights provide a significant improvement in color quality, and also significantly increased the brightness of the image.However, many people will have is a legitimate question that is better to choose - Edge LED or Direct LED.For each option has its own advantages and disadvantages that must be considered in the selection process.
What are their main differences?
To date, all existing major TV manufacturers are using only two types of backlights - Edge LED or Direct LED.Between themselves, they differ in the number, as well as the geometric arrangement of the LEDs.Depending on how the last located, may change the characteristics of the matrix, each illumination type has its own characteristics and advantages.For this reason, choosing a TV, in each case, you need to weigh all these things and think about what it is better to choose - Edge LED or Direct LED.Next, we consider the features of each option.
Application of the LED backlight provides distribution on the sides of the screen.Therefore, this technology is often referred to as the side lights.
Plyusov this technology has several:
- Extremely thin matrix, and in this context - and the television itself.
- relatively high brightness.
- acceptable level of contrast.
The main advantage of this technology is that the TV could eventually be hyperfine, which often acts as a decisive factor in favor of the choice of such devices.Today seen a clear trend toward that, choosing between Edge LED or Direct LED, often give their preference to the first embodiment, for the reason that modern manufacturers produce ultra-thin screens with the technology.
Also worth noting is the fact that the lateral distribution of LEDs provides a high degree of energy efficiency.
Also, technology has certain drawbacks:
- lit up the edges of the screen.
- Problems with uniform illumination in certain models.
If you opt Edge LED, it should immediately be prepared for the fact that the cost of the TV will be a few more, since they use a specialized reflective surface required for extremely uniform distribution of illumination, as well as eliminate any noticeablefluctuations in brightness.If we talk about what are the disadvantages of this technology is to provide the presence of certain flashes on the edges of the screen, and when you play, for example, bright snowy landscape snow near the edges of the screen will be much more striking when compared with the image in the center.
in dark scenes and quite often you can pay attention to the effect of a kind of glare, and, in particular, due to the fact that LEDs are located on the perimeter of the screen, and the brightness in this area is quite logical.It is worth noting that various different TV show will light up as a result there is always the possibility that you will be able to find the device with the smallest possible differences pictures.If the TV is present in a function as local dimming, then in that case you can forget altogether that is lighted, and that they can spoil the mood of the view of certain moments.
Type Direct LED backlight provides distribution of LEDs over the entire area behind the matrix.
In this case, a very efficient and convenient enough to be used by local dimming technology when the processor sets the brightness of certain groups of the LEDs, thereby increasing the contrast ratio, while providing very uniform illumination.
Considering the benefits of Direct LED, is to provide the following:
- uniform illumination.
- fairly high level of contrast.
- Lack of edges glow.
- acceptable level of brightness.
lights LED Direct also has some disadvantages compared to analogue:
- higher power consumption.
- Not such a thin thickness of the matrix.
- relatively large Input Lag.
What to choose?
As mentioned above, there is no exact definition of a specific option is more relevant in a given situation.It is possible to pay attention to a number of factors when choosing between a more optimal variant, - Direct LED and Edge LED: where better picture quality, where more energy is consumed in the end what the TV has more attractive design itself.
Thus, if the thickness of the device for you has no role, and even in this case you have no intention to use it as a monitor for a variety of computer games, in this case is quite suitable illumination technology Direct, but if you're a fan of extremely thindevice, then the Edge - is the best choice.It is better to compare the performance of each of their own lighting in the store, so you can decide yourself which specific option is more acceptable.According to the users of televisions, ultimately the choice of illumination in many ways a very matter of taste of each person.
